|Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Matthieu N||12/13/13 12:19 PM|
Yesterday I received the 4.4.2 update for my Nexus 5 (directly from 4.4) and today I saw that my battery decreased much faster! (At least twice as fast.)
In the battery usage menu, I can see that it is the "Android OS" which used between half and three quarters of my battery, without even using my phone.
(At the moment I can read 53% for "Android Platform" and 13% for the screen, this never happened before.)
The use I made of it is strictly identical to previous days, it remained in wi-fi at home, with brief uses, so I think that this "Android OS" battery drain is due to the update.
What can I do ?
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Ted Turner83||12/13/13 1:16 PM|
I also have noticed that AndroidOS will have a huge "Keep Awake(Settings->Battery->AndroidOS)" amount while on Wi-Fi at home, but if I turn Wi-Fi off, it stops staying active. (Using Nexus 5 Android 4.4.1/4.4.2; I did not have 4.4 long enough to test).
I changed my beacon interval on my router from 100 to 50 and DTIM from 1 to 20. This fixed it last night at least, though it also ended up rebooting the router so I will need to evaluate more. This was not a problem on my Nexus 4 using Android 4.3-4.4 or my Galaxy Nexus using Android 4.0-4.3
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Matthieu N||12/13/13 2:28 PM|
I think that I just can't do this with my router...
However I found a thread on xda with other people complaining about the same issue :
Is there any way to contact a Google tech support or something ? Those "Help sites" keep bringing me here when I look for a tech support.
I hope they are aware of this issue.

This has been happening to me for about 3 weeks now. I'm in Australia and not sure if OS updates are pushed to all regions simultaneously.
I bought my Nexus 5 on the day it was released. For the first 2-3 weeks battery life was normal, then *I think* around the time the first update was pushed to my phone, my battery stared dying very quickly overnight when my phone was idle (I charge during the day, not night).
A fully charged battery lasts less than 8 hours now, when the phone is sitting (unused) on my bedside table.
* Bluetooth is OFF
* NFC is OFF
* and location history are OFF
* Phone is connected to home WiFi network when I sleep
* I have tried factory resetting the phone twice (via Settings) - this had no effect
* Screen turns off after 1 minute of inactivity
* Brightness set to auto (should not matter as screen is off)
* Notification pulse light set to OFF
* I have tried using an app killer (AVG) to shut off unnecessary processes - again no effect
I know another person that is having the exact same issue. Battery life is reasonable during the day, but the phone just does not 'sleep' at night like it should.
I've been dealing with Google support but getting nowhere, they are now sending me a replacement phone despite CLEAR evidence that this is an OS issue. If someone from Google is reading this I'll be interested in hearing what you have to say.
See attachments for a typical example of what happens when I lay my phone down fully charged and go to bed.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Ted Turner83||12/14/13 5:17 AM|
I entered Safe Mode and did not see the issue after ~2 hours. Just normal drain. I'll test it again overnight tonight for longer to verify. Though I also noticed Google+ Photo Sync finally stopped showing the White Circle with Arrows. If that means anything.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||neiander||12/14/13 7:22 AM|
My battery has gotten worse since the update too. Says that the Android OS is taking at 16% AND Android System is at 7%. Why are there two? I have had the phone off the charger for nearly 3 hours and down 25% with only about 45 minutes of screen time.
Completly stock New nexus 5. 4.4.2. has created some new battery issues with me.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Man44||12/14/13 12:44 PM|
Same problem here. I understand it doesn't help to just reply saying 'same problem' without offering a solution, but I hope Google takes note of all these complaints and begins a level of being proactive to solve this otherwise very big issue. It is literally a make or break deal for me - if I cannot get a phone to work properly for which I paid $400+ for then I need money money back in order to get a Galaxy or HTC with bigger battery.
Google: Please fix battery issue that's caused from latest system update last week...
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Ahmad Naif||12/14/13 6:39 PM|
Same here. Plus my device is getting hotter even though i was just browsing the web.. It is not like this before the update.

|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Anthony Hurd||12/15/13 7:13 AM|
I called Google and told them my battery was dying everynight. They refused under any circumstance to issue a refund. When I told them I could not use my phone as an alarm because it died everynight their only suggestion was to find a way to plug it in.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||bobpower||12/15/13 2:31 PM|
I have fixed my issue.
By changing two settings, I went from 100% battery depletion overnight (when phone was idle) to only 4% last night.
1. Settings > WiFi> Advanced > Keep WiFi on during sleep: change from 'Always' to 'Only when plugged in'
2. Settings > Location > Mode: change from 'High accuracy' to 'Battery saving'
To be honest I suspect the first setting is the culprit. When I woke up this morning and saw only 4% battery had been lost, I then changed Setting 1 back to 'Always', then went and had a shower, got dressed and ate, which took about 40 minutes. When I checked my phone after that, it had already dropped from 96% to 88%, in only 40 minutes when I had not touched the phone except to change that setting back.
Read that again. It used double the amount of battery in 40 minutes, versus what it used in 8 hours with 'Only when plugged in' set.
My theory is this: when we first got our phones, out of the box that setting was set to 'Only when plugged in'. Then either updates 4.4.1 or 4.4.2 changed this setting to 'Always'. I have no way of verifying this, but I know during the first two weeks I had my phone (before 4.4.1 was released), the battery behaved exactly like it did last night after changing the setting.
There is another WiFi setting in the Advanced menu 'Scanning always available', I think un-ticking that will further improve battery life during the day.
YOU'RE WELCOME BITCHES.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Ahmad Naif||12/15/13 4:07 PM|
Thanks bobpower... I'll try and change the settings first... And just have a day with my device...
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||preahchan||12/15/13 6:57 PM|
Hi bobpower, I'm having the same issue after updating to 4.4.2. My phone becomes very hot when left idle over night and drain the battery like crazy, when checked it's the "android system" that drained most of the battery. I'll try your suggestion and see if it fixed this issue. Thanks.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||alamarco||12/15/13 7:07 PM|
Unfortunately bobpower's solution is only a workaround.
It's a workaround that will only work for some. As someone who is without data for 8+ hrs at work I rely on WiFi so I can't turn WiFi off during sleep. My battery was fine before the update, so something is amiss.
Hoping Google can take a look into it, but seeing as no Google rep has responded, not very hopeful.
Anyways, hopefully the solution posted works for people, but hoping Google takes a further look as some people need a solution.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Javier V||12/15/13 9:50 PM|
I'm also having this issue. I'm glad I'm not the only one though and hope that Google can fix this very promptly with an OTA update. My battery is depleting super fast and I'm not even using it that much! Also, it is taking forever to charge the phone. I leave it charging the whole night and it only makes it to 70%. Please fix this Google!
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||wanderingtim||12/16/13 12:50 AM|
updated to 4.4.2 earlier last week
drained 10% from home to work just doing normal browsing + listening to music during 20 minutes!!!!
that's just not possible!!!
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||preahchan||12/16/13 1:19 AM|
I've tried bobpower solution and it doesnt seem to help and the my phone still drain battery like crazy and it's always that "android system" is the culprit.
I hope someone could come up with fix.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||ecMan||12/16/13 1:21 AM|
Android OS doesn't necessarily mean the OS is actually draining the battery. 3rd party apps can be calling certain APIs that delegate certain tasks to the OS, like perhaps location services, such that the battery app actually reports Android OS rather than the app that was calling the app.
I have WiFi set to always, and 4.4.2 doesn't give me any significant drain at all. It actually drains less than 4.4 did. I did have a drain issue reporting Android OS a while back, but when I uninstalled a Vegas slot machine game, the drain on Android OS disappeared.
And fwiw, on my Nexus 7 2013 the Google experience launcher sucked batteries, and it too was listed as Android OS. When I switched back to the stock launcher my drain returned to normal.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||simonbaptist||12/16/13 5:25 AM|
+1 on this issue. A bit embarrassing as just the day before the update I was lording it over the iOS users in the office.
Anyway, trying bobpower's workaround ahead of Google fixing this.
FWIW - I am seeing
Android System: 18%
Android OS 9%
|Battery drained by "Android OS" since 4.4.2 update on Nexus 5||John Whittle79||12/16/13 7:50 AM|
Just want to say that I am experiencing the same issue. Battery draining much faster on 4.4.2
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Adrian Bordoy||12/16/13 9:21 AM|
Same for me people,
losing 30% overnight since 4.4.2 with android OS being at the top of the battery stats.
on 4.4 it would drop 4% overnight..
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Michael Schlechtinger||12/17/13 12:24 AM|
I am experiencing the same issue since I got my Nexus 5. I never had this problem on another device before. However I found a workaround. If I restart my device after charging the battery it's working for at least 2 days. If I do not restart the device I do not get through one day. It's really annoying!
|Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Mo Jiwa||12/17/13 3:11 AM|
Exactly the same. I had the same power settings before 4.4.2 as I do after the update and now it's shockingly bad. Even with screen off and wifi off.
Just adding to the complaint list.Google, please fix ASAP. This is the reason I got rid of my iPhone.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Stéphane Cochard||12/17/13 4:43 AM|
Same here with my Nexus 5 with Android 4.4.2.
Yesterday night, my Nexus 5 has charged in the living room, so at midnight its battery was 100% charged. Then I came to bed, Nexus 5 unplugged to use it as an alarm clock. This morning, at 7:30, the battery was at 24%. 76% consumed while sleeping?! Please Google, fix it!
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Chung Lau||12/17/13 9:15 AM|
Same here over night my android OS and wifi consumes the most battery.
Some suggest to turn on option to "keep wifi on during sleep" to only when plugged in, see if that helps for you.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||hedwigdaowl||12/17/13 11:15 AM|
Same here. Android OS is the top consumer with the keep awake time being almost 75% of the time since charge. Insane. On 4.4.2 , moto x. Even if its some app delegating work to the OS, why can't we get a little more info as to what part of the OS task is killing the battery? Duh.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Paul||12/17/13 2:12 PM|
Android OS is one of those background processes that manages a lot of things in the Android system, so it sounds like something is keeping it awake and running overnight for some of you. As Ted Turner83 mentioned earlier in this discussion, try starting your device in safe mode (instructions and info here) and not running any apps you've installed to test if one of them is causing calling on the system overnight and draining battery. If you don't experience the problem while in safe mode that's a good indication that an app you've installed is the source of your issue.
|Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Mo Jiwa||12/17/13 3:37 PM|
I'd have to disagree with that last one... Unless of course the most recent update has caused an app to behave differently.
Literally the only change on my phone between the battery being awesome to the battery bring terrible, is 4.4.2.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Eyal M.||12/18/13 12:56 AM|
I know that this is a Nexus 5 thread, buy i have updated my SG4 GE to 4.4.2 2 days ago, and i'm facing the same battery drain issue.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Dmitry A||12/18/13 2:29 AM|
My nexus 5 in safe mode drain battery when wifi is on (wifi point is D'link). When i try run in safe mode at work, battery is ok. Wifi at work isn't D'link.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Anirudh Sampath||12/18/13 3:47 AM|
My phone is even worse...it lasts only 3 hrs and 45 minutes on ful charge with only pre-installed apps, and nothing on.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Константин Селеронов||12/18/13 12:33 PM|
The same problem on my Nexus 5 (4.4.2). The battery charge barely lasts for 10 hours with WiFi on, average devise usage and almost no phone calls. 3h. 30m. of the screen usage. Something is deffinitely wrong
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Mo Jiwa||12/18/13 12:36 PM|
Okay... experiencing new really weird behaviour... changed NOTHING and battery is back to normal again?!?!
Will keep monitoring to see if it's consistent.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||hedwigdaowl||12/18/13 12:44 PM|
I am experiencing a better battery life today. I did make the two settings (location and wifi sleep as suggested) last afternoon and it did not help until last night. It drained at the same rate. This morning I did wake up to a bunch of google apps being updated and my battery has lasted well so far. Too early to say, but could be the google apps update?
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Hamid Bhurgari||12/19/13 1:39 AM|
If it helps, HTC One on 4.4.2 has the same issue. Battery lasting half the time it used to. Google OS is taking up 80% of the battery usage. I have all the usual suspects turned off too.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||CK0000||12/20/13 4:52 AM|
Same here. The update process for the Nexus 5 has been a train wreck. Disappointing.
|Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Dmitry A||12/20/13 9:17 AM|
Last 2h 30min ok. Wifi,geolocation, sync are on! Battery lost 1%. All what i'm change is setting wifi access point. I change DTIM interval from 255 to 20.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Y.Gong||12/20/13 7:10 PM|
Me too! Fully charged phone can only standby 9 hours without any use!
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Ted Turner83||12/20/13 7:28 PM|
Factory Reset, did not use ART and stayed with Dalvik. 2-3 days with no unusual battery drain. Feels like ART messed something up and even reverting to Dalvik wasn't enough, had to do a reset.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||jplehmann||12/21/13 9:55 AM|
I've had my phone for a week or two and because of all the problems I've read about I'm sticking with 4.4 even though it has downloaded 4.4.2. I'm holding out for 4.4.3 which I hope Google is sending soon!!
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Peter Szczerba||12/23/13 3:57 PM|
Same for me, Android OS and Android system are consuming over 50% of my battery, with a complete discharge happening in 7 hours of average use. I am using a nexus 5 with android 4.4.2, all my battery issues started after the update. My device is showing 4 hours of awake time in 7 hrs of use, and my WiFi is showing 8 percent of battery use even though its turned off.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Elias_Grodin||12/24/13 8:01 PM|
Same for me as well. My Android system and OS are draining a lot of battery after the 4.2.2 update. This is extremely disappointing to say the least. The battery dropped more than 30% over night with my phone on the bed side with even the data and Wi-Fi off. To mage things worse, kit kat no longer works with wake lock detector so I have no idea what caused the problem.Google please fix asap!
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Raphaël Cazenave||12/26/13 4:13 AM|
I had the same issue, i disabled "Google Play Services", cleared the cache of all Google Related Apps, Uninstalled All Updates of Google Related Apps, and it seems to solve the issue on my N4. A Factory Reset works too.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Michael Cassidy||12/26/13 7:37 AM|
Same here. My phone will often deplete its battery up to 75% (from a full charge) while sitting idle overnight. -But other times it will only use ~6%. Very frustrating.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||judtoff||12/28/13 5:17 AM|
I am seeing this problem too. Setting the wifi to stay on only when plugged in is not a solution. It's still draining 20% per night. For some reason the wifi is staying on, even when it should be off.
Something is preventing the phone from going into deep sleep.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Murray Rush||12/28/13 10:23 AM|
Just had N5 go from 100% to 0 in 6 hours overnight due to the Android OS With 5 hours of CPU time. Something's not right here.

|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Scott Qc||12/29/13 5:24 PM|
I have the exact same issue with my nexus 7 since I installed 4.4.2. When I turn wi-fi off the tablet loose 3-4% overnight. When it's on I need to recharge the next morning, it was never like that with Jelly Bean. Come on Google, do something it make no sense.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Naveen Menon||12/30/13 9:46 AM|
My nexus 5 has been perfectly good.. i even got a screen-on time of 6 hours and 11 minutes.. and my friend got a bit more than 7 hours after the update.. and battery easily lasts a day.. i swear i am not lying.. will post screenshots once my dad gets my phone back from wherever he has gone.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Scott Qc||12/30/13 11:20 AM|
I must add that I'm also connected with a dlink Wi-fi at home. I don't know if it is relevant or not but it was mentioned in previous posts. But I never was an issue with 4.3. Moreover I tried to change MTU values but it did not help.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Dmitry A||12/30/13 11:23 AM|
Try to change DTIM to 20 -it's help to me.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Scott Qc||12/30/13 11:29 AM|
Oh, sorry I wrote MTU but I meant DTIM. I tried changing this value from default 1 to 20 without any improvement. I will try it again just to be sure.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Dmitry A||12/30/13 11:32 AM|
Try to reboot all: access point and nexus.

I changed DTIM for 20 and rebooted router and nexus. I saw a small improvement, its was at 21% this morning after a full charge in the evening. Yesterday it was 13%, but this is still not acceptable. Waiting for 4.4.3!!!
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||AlfMaster||1/3/14 4:29 PM|
Exactly the same here. f I restart my NX5 after charging the battery it's working for at least 2 days with about 1.5 hrs of screen time. If I do not restart the device I do not get through one day with the same screen time.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Anton Rothwell||1/6/14 6:54 AM|
Also seeing this on Nexus 10 with 4.4.2 update. E-Mail client consumes all battery. I have 1 hotmail account and two gmail accounts setup. Hotmail is set to sync e-mail only but with no auto sync options ie: frequency is set to never. Gmail accounts update every 5 mins. Can stop it consuming battery by force stopping the e-mail app after use.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Hamid Bhurgari||1/6/14 7:20 AM|
This is the correct fix. Worked for me. Battery is back to lasting almost 39 hours.

I'm seeing reduced battery life with my Nexus 10 since the update. It's not extreme like overnight, but I used to charge my tablet every other or every third day and now I'm having to charge it daily. The Android OS is draining >50% of the battery and reporting 15 out of 22 hours as keep awake even though the device doesn't show significant keep awake in the battery % vs time chart. Not sure what's going on but I'm almost positive it's related to Google Apps.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||KennyG944||1/9/14 7:31 AM|
That new update is probably sucking up every photo and video you have saved on your phone regardless of your settings. You can bet your ass that Google is in bed with those bastards over at the NSA. Every update they push out puts more of your private life in their hands.

Ironically, I had never enabled Google+ Photo Backup, but I enabled it yesterday to try it out and hit sync and it said it was syncing 2270/2300.........so it had already synced 2270 of my photos even though I've never enabled it.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||KennyG944||1/9/14 7:49 AM|
My point exactly! They're backing up your photos and videos, even if you have the feature turned OFF! They can hide the fact that they're backing up your photos and videos without your permission. But they can't hide the battery drain it takes to do so!

Been reading this thread as I am (was?) interested in buying a Nexus 5. However, the reports of poor battery life are making me hold fire on pressing the 'Buy' button. I think this is an OS problem as the upgrade to 4.4 has buggered the 'idle' battery life on my Nexus 7. In addition, but not entirely sure if it's relevant, since the update 3rd party battery monitor apps do not work on my Nexus 7 when they did before. I have to manually refresh them. Something is not right
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Brianexus5||1/10/14 4:52 AM|
Been having this problem lately as well. Currently drains like 80% while idle for 8 hrs. Checked hours phone on and it was 190 hours. Restarting and reporting how it goes!

Dissable all to make nothing of nothing (Wifi,Bluetooth,Syncro,notification,widget,localisation, no apps) 100%to 49% battery in standby this one night compare to 100% to 99% with Xperia SP 4G at same place and same time.
Put 4G to 3G parameters this morning , only 99% to 95 % with fews mails and 30 minutes roadway to working place !!!!!!

I cleared data/cache for G+ and Google Services, restarted the device, and things have improved dramatically. I'm now losing <10% over night on standby.

I wonder whether 4G is the issue. If the handset is having to work harder to find/hold a 4G signal when coverage is still not 100% then it will suck power from the battery. FWIW, on my commute to work in NW London there is a chunk of the train journey where the 3G signal leaves a lot to be desired. Similarly, if wi-fi is always on and apps are doing/able to do their thang.
So, is it KK that is the issue or 4G/LTE in those areas with weak and/or incomplete coverage?
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Murray Rush||1/16/14 12:39 PM|
I've only had 100% battery drain overnight once and I had my phone set to 3G only. This is just my experience with the random battery drain though.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Gooner1986||1/16/14 1:22 PM|
Were you at home or somewhere else that you know whether there would usually be a good (or at least predictable) 3G signal from your network provider? If you were at a friend's place or something then maybe 3G or 4G would be irrelevant. My signal is good at my home but total pants (British for not very good) at my mother-in-law's in Kent.
I appreciate there is an underlying 4.4 OS bug that is thirsty on power but there could be any number of other issues that will make the experience different from one person/phone to another and then again from day to another. ??????

Solve default deep sleep in stand by and battery rain with 4G LTE & syncro on , wifi & loca off : battery 100% to 99% in one night
Remove all Widgets
Make 2 manuals setting :one APN web (default,supl) & one APN mms (mms) with IPV4/IPV6 & LTE
Reset to 0 cache of appli G+ & service google play
OFF /ON phone
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||MC Wong||1/17/14 7:13 AM|
The new google play services 4.1.32 recently rolled out should have resolved the battery drain. It will be updated automatically very soon if not received yet.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Ted Turner83||1/17/14 7:23 AM|
Prior to Google Play Services 4.1.32, I would randomly find a high Android OS wakelock on Wi-Fi. Since 4.1.32, I have never seen this issue and also experienced a deep sleep over Wi-Fi increase from ~93% to ~98%. 5% improvement in deep sleep overnight, while on Wi-Fi.
Hopefully others will see this improvement with the new Google Play Services update.

are they really serious to want us to plug the phone ever night. they don't know, doing that will lower the life of the battery, and then if you told them my battery is dead they will answer, you shouldn't kept it plugged in.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||ecMan||1/20/14 10:26 AM|
That's actually not true with a Lithium Ion battery. It's actually the exact opposite. Deep cycling the battery will lower it's life of the cells.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||shiverma||1/22/14 5:32 PM|
I did not try what you have suggested. I do have an observation. I generally turn leave 3G(LTE is turned off as I am in India)/WIFI/GPS off (I have turned off all background scanning that Google services need). I still did not understand as to why my battery would last not for more than 1 day and 9 hours before going down 20 pc. I also have a Nexus 7. I saw that it lasts 5 days without losing much charge. Of course, it's a different device, but just to see if the phone could behave the same way, I put it in Airplane mode and noticed that battery drain had stopped happening. Is the phone being too aggressive in looking for a GSM network or is it something that I am reading wrong here? I used a Galaxy S2 before this, and using it the same way used to get me a good 2+ days of battery life.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Hai Vu||1/24/14 8:31 AM|
I have the same problem of draining battery when use 4.4.2, but when I switch to Dalvik (instead of ART), the battery is much more ok now.
SO PLEASE SWITCH TO DALVIK WHEN BATTERY IS DRANING.
AND GOOGLE PLEASE FIX IT ASAP.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||shiverma||1/24/14 10:22 AM|
I was actually running Dalvik till now. I have changed it to ART, I'll keep an eye on things to see if things change for me.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Memo Ak||1/24/14 11:42 AM|
I got my Nexus 5 last Friday and the 3 days after using it, battery was really good, Android 4.4.2. Actually I charged my phone Sunday night (Disconnected it Monday 8:00 am) and it was able to make it to Tuesday night (10p.m.) Wifi on, normal twitter, whatsapp, facebook, youtube, etc use. I activated Google Now and that's when I noticed battery being drained pretty quickly. I deactivated Google Now yesterday and everything looks good now, I'm assuming that some widgets, google now, and some other apps are requesting location really often, and that is tracked as Android OS usage. Also now I've been running with my battery for 5:40hrs and screen is 25% and Android OS 7%, which makes more sense to me.
Anyways, I don't like this workaround of deactivating some apps or features to get more battery time.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Amedeo Russo||1/25/14 4:11 AM|
I got my Nexus 5 last Wednesday, and this is the environment I'm running on, since then:
- Android 4.4.2 (already on the phone when I got it)
- Dalvik compiler on (never tried ART)
- Google Play Services 4.1.32
- Location Settings: WiFi only
- Wifi scanning options: "always scan" disabled
- 20 apps installed
- No widgets apart from Keep
It was all fine since this morning. Last night I put my phone in airplane mode with 70% battery life left, and woke up to find the phone had switched itself off during the night, due to a MASSIVE battery drain by Google Search (checked it up on the battery details).
How is this possible, given that I have everything updated to the very last version?
Apparently, last Google Play Services didn't fix the battery drain issues.
Google Support, please give feedback on this matter and work to fix it ASAP.

97% drain via Android os overnight whilst plugged in. Woke up to a dead phone. I've had this phone 2 months with no problems beforehand and no new apps. My phone is a posh paperweight at the moment.
|Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Scott Qc||1/26/14 6:01 PM|
Ok, I have a Nexus 7 and I tried all the suggestions that were here. I tried with a full reset of the device and it was better but not perfect.
I finally found that it might be the wifi security protocol that is causing trouble with android 4.4.2. At home my wifi is secured with WPA2 and I have an extreme battery drain cause by "Android OS". This issue disappear when I change to WEP. This is not something I want to do because it weaken my network security. But I hope this can help Google fix this issue.
Can somebody else try this and tell us if it helped.
|Battery drained by "Android OS" since 4.4.2 update on Nexus 5||MC Wong||1/26/14 8:55 PM|
Could it be the router needs to be rebooted? Maybe it's not transmitting or transmitting intermittently causing the device battery drain.
|Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Scott Qc||1/27/14 4:38 AM|
I don't think so. I also have a galaxy s4 (android 4.3) and I don't have any issues with it. Moreover, the router was rebooted a few time when I was changing my router settings and security protocols.
|Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Carlos Mendoza||1/27/14 5:01 AM|
I just started experiencing the same issue, my battery lasts for 4 or 5 hours tops. In the battery usage it says mm-Qcamera-daemon is the responsible of 37% batt usage.
|Battery drained by "Android OS" since 4.4.2 update on Nexus 5||_jason_24||1/27/14 11:24 AM|
Try turning wifi optimization off. I did a bunch of things like change my dtim as well, the drain is not as bad now.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Wilson Ko||1/28/14 7:20 PM|
There seems to be a bug in the radio driver of the nexus 5 not powering down the LTE radio when there is no data transmission. This problem occurs randomly. I had this occurred to my Nexus 5 several times. When this occurs, nothing is reported to be consuming the battery in the battery usage log. Yet, the battery goes down by a few percentage every few minutes.
Some workarounds that I found are:
1) reboot the phone
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||_Matt Allen||1/30/14 11:05 AM|
I have a Nexus 7 (Wifi only) that has the same problem. My device was in standby overnight and drained from 100% to 1% in 16 hours, without ever being touched. 67% Android OS, 13% Android System. I used to be able to leave it on standby (idle, w/e it's called when it's doing nothing) for days before it would drain completely like that. To my knowledge, the only change that could have done it was the most recent android update.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Schnarff||1/30/14 11:52 AM|
In the interests of fairness, I should now say that the problem seems to have rmiraculously resolved itself. I'm still on 4.4.2. Seems like a temporary, albeit bizarre, blip.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||tiltshiftfocus||1/31/14 4:04 AM|
My understanding of these random Keep Awake or battery drain when idle is Google love to play around with their 'services', drawing unnecessary data from our phones.
And for battery drain in airplane mode, my guess is that there are 'unfinished' processes from the services that causes it.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Fred T.||2/1/14 12:59 PM|
I've tried Art and Dalvik and no difference. It is disappointing that Google can put out out a device with a smaller battery than this device should have. That would be fine if Android could manage it better. Every release they say is better and better but users still have the same nagging issues. The Android OS using 40-70% battery is ridiculous. They need to address this in the next update. I'd pay another $100 for this device for a few more tweaks if that's what it took, however we are even seeing more expensive non Nexus devices with similar issues. My Nexus 7 is phenomenal with its battery life. Battery saver apps don't seem to work. Putting WiFi off at night doesn't work. The strange thing is the erratic behavior. Some nights you'll only lose 5% battery and others 50%.

|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||_Matt Allen||2/5/14 5:40 AM|
I found and addressed the fast-draining battery issues i was having on both my nexus 7 (wifi only) and my moto X.
When I paid more attention to the battery drain graph/curve, I noticed that (at least in my situation), my phone battery was draining normally while I was at work, but at home the decline in remaining battery was nearly doubled.
There were only two differences that I could think of between home and work (I don't have any location-based profile apps that i'm aware of, except whatever google now does). One is my cell phone signal, which is far greater at home than at work. The other is my wifi, which is decent at work, but at home my router has been frequently dropping signal to wifi devices in my home. Maybe it was a fluke, but when i fixed the wifi router at home so that it stopped dropping wifi signal so frequently, both my moto X and nexus 7 went back to normal (great) battery life.
So, maybe it was a fluke, or maybe 4.4.2 introduced something that doesn't like poor wifi signal. Either way, my battery life is back. Hopefully that can help someone!
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Gustavo Pinto||2/8/14 4:36 AM|
Definitely a problem related to wifi reception, though I wouldn't blame the router. Since the update, I notice Android OS ballooning out of control and showing wifi signal to be poor. However, control devices nearby (3, including a Galaxy Tab and a TV stick stuck on 4.1) show no variance in wifi signal strength. If I reboot the phone, wifi signal promptly reestabilishes itself and the battery stops draining wildly. If it happens at night, the phone will completely discharge. Very annoying, but not as annoying as the complete silence from Google on the matter.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Thomas Matt||2/10/14 2:44 AM|
My router is literally 1 meter away from my phone, reception is perfect (well, should be). And yet the battery drain is back.

I think I may be on to something! I've also had this problem with only the WiFi router at my work. The other day, I noticed G+ auto picture uploading was sort of stuck and not uploading photos why I was at work either. So I cleared the data/cache on the G+ app and then changed to auto picture uploading to only happen on WiFi while plugging into a power source. Now, it's been two days on the office WiFi without the crazy battery drain! Hope this helps.

|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Steven||2/20/14 7:38 AM|
I get the same battery issue every now and then as well. One thing I noticed is that when the AndroidOS drains like crazy, another process called Sensors.qcom is draining some of the battery as well. When the battery drain acts normally, Sensors.qcom doesn't show at all. Thomas Matt, I noticed the same thing in your screenshots.
Does anyone know what the Sensors.qcom process is? I feel like that may be causing the AndroidOS to act all crazy.

I have the same issue. Nexus 5. First two weeks I had the phone I was blown away by how good the battery life was. It was amazing. Then I got 4.4.2 and now if I leave it running overnight it goes from 100% to 55% just sitting on my dresser. The primary culprits are wifi and system idle.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||daholby||2/21/14 11:36 AM|
Straight Linear battery drain. Phone has been idol most of the day barley used, and in 4 hours I'm at 20%. Same contestant drain even when phone is one and playing a game.
That little sliver is when I restarted in Safe Mode and still getting the batter drain. OS issue.
Unacceptable. I can NOT use this phone for daily use now. Both me and my wife are experiencing the EXACT same issues at about the same time (both have the Nexus 5). Something is going on here. Google needs to fix this.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||MikeWelch||2/21/14 12:02 PM|
Definitely an OS issue, but you can work around it by turning off WiFi. Not sure how much cellular data you get but turning off WiFi definitely stops the bleeding, although it is not an acceptable solution.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Fred T.||2/21/14 12:17 PM|
I've been rebooting the phone every two days or so. I installed Greenify app that shuts certain apps down. I also turn off Bluetooth and for location I put it at the lowest setting before bedtime. If you have any LED light notifications I'd put those to sleep overnight. They drain the battery. So far so good.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Yue Liao||2/21/14 7:23 PM|

Thought I would let everyone know that my old router that I was connecting to was causing the issue when wifi was turned on. I switched it out for a newer, (but not as powerful) router and the issue is completely gone. Still have wifi enabled, connecting to a different router and no battery drain. Good luck!
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||MikeWelch||2/22/14 6:17 PM|
Yes, it is definitely something to do with certain routers. Unfortunately, I cannot change the router at my office, so I just have to disable WiFi at work until Google fixes the issue.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Gustavo Pinto||2/23/14 2:43 AM|
I have downgraded to 4.3 and, to my surprise, the problem isn't totally gone. Android OS is still keeping my device awake for 9 hours at a time, though the device doesn't get hot, battery drain isn't as severe and wifi signal doesn't get poor in the process. Which means it's not exactly KitKat that's causing the issue, it's merely aggravating it. I have installed Wakelock Detector and the main culprits seem to be Exchange and a Google process called 1013, which has something to do with audio though since the wipe and 4.3 flash I don't even have any media on the device. Will keep looking.
|Battery drained by "Android OS" since 4.4.2 update on Nexus 5||RedDr&Dr||2/23/14 5:54 AM|
After reading this entire thread and trying most of the os setting tweaks, I noticed almost immediate battery performance improvement by turning off Google Now. (~10% battery charge lost overnight, which I consider fantastic now. Low standards?)
|Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Fred T.||2/23/14 6:05 AM|
Not sure how the router can be blamed. The radio for WiFi is the same in every Nexus 5. If your living space is 2k feet or less, which is the majority of most homes then your modern day router is capable of working well within that range. Again, I've found changing location settings to low battery use and turning Bluetooth off at night to help well. Also the app called Greenify allows you to put asleep any app that is running in the background. I've also rebooted the phone in between doing these things every two-three days. When you reboot it is like a refresh of system processes running at their lowest levels. I can go a day and a half on a newly charged battery now. Try it and stop messing with routers and turning Google now off. Sure it could be any app you installed that is draining the battery and that is where Greenify comes in. You don't have to be rooted to use it. Good luck!
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||gpeng05||2/23/14 12:49 PM|
Count me in - new Nexus 5 as of last week, and overnight battery drain under certain circumstances (home) is ridiculous - dead battery within 5 hours.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Steven||2/23/14 12:54 PM|
I get the same AndroidOS drain even with wifi and mobile data turned off. It just happens randomly with the phone sitting and the screen turned off. It would be nice if Google would at least confirm there's an issue with the OS.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Gustavo Pinto||2/23/14 12:59 PM|
Well, "Android OS won't let my device sleep" isn't exactly a productive bug report. From what I've read so far, our problems might not even be the same. So running BetterBatteryStats or a similar app and finding out exactly what process is sending those keep awake signals is a must, for starters. Everything seems to point to a new version of a Google app, at least in my case, since I have reverted to 4.3, installed no third-party apps and still spotted similar behaviour. Since the last reboot this morning, my phone is idling again. We'll see how long that lasts.

That's not a solution more like a band aid. You are also giving up any improvements such a security updates. Go up several posts and see my solution. Its working great. Reverting back to an older version is not the answer.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||MikeWelch||2/24/14 7:31 AM|
I saw your solution, but it is not feasible for me. Google Now is an important part of my phone -- I use it all the time. My workaround was to just "forget" my office's WiFi network. As soon as I connect to the office router, my phone remains warm and battery drains about 10-15% per hour. As soon as I disconnect, the phone cools off and battery usage drains at the normal rate. I have no idea what it is about the office's WiFi router and I do not have this issue at my house, but I do not have access to mess with the company's router settings and the network guy has no idea why this would happen. It is an older, corporate strength Cisco router, so perhaps there is something about it that causes the "Android OS" process to continually chew up battery. Maybe there's some weird security on it or something. I know it seems unlikely that a router would cause this since WiFi is so common, but I can reproduce the battery drain reliably and consistently EVERY TIME by simply connecting to that router. Then as soon as I disconnect, the drain stops.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Fred T.||2/24/14 7:42 AM|
It is possible the phones battery has an issue if it drains that bad. Do you notice any difference after restarting the phone? How about plugging it up to a USB cable for charging instead of the charging plug that came with the phone? I've noticed slower draining after using USB to PC when charging it at any number of percentage the battery is showing.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||MikeWelch||2/24/14 8:40 AM|
No, I'm pretty technically savvy and understand Android very well. I'm actually going to be doing some Android development at work here soon. I don't have a bunch of unnecessary apps installed on my phone and use Greenify to hibernate any unnecessary background services. My battery has been fine now for the past 3 weeks since I pinpointed the issue. After a 15 hour day, my battery is usually around 60% with moderate use throughout the work day. I still try connecting to the office WiFi once a week or so and like clockwork, after a few minutes on the office WiFi, the phone will get a little warm and battery drain will noticeably increase. In the process of figuring out it was the office WiFi, I wiped my phone and re-flashed the factory 4.4.2 image Google provides and the drain was still there. I was always on stock, so it's not that I could even blame it on a custom ROM. So by wiping the phone, I eliminated any possible apps and I was getting ready to request a replacement when I noticed over a weekend, battery life was great. I was dumbfounded that then on Monday when the drain started again. Trust me, I am 100% sure that (at least in my case), the drain is related to being on the office's WiFi. I have no idea what it is doing while on the office router that is causing the drain, but it definitely happens. I've tried some root apps that will show battery usage in better detail and it's the kernel process that spikes when I'm on the office WiFi. I'm baffled, but just glad I was able to find a workaround. I'm on an unlimited data plan, so I don't mind being off WiFi at work.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||gpeng05||2/24/14 2:03 PM|
I switched to ART the other day, and oddly it seems to have helped a ton - back to 1%/hour idle usage. I know somebody else got it to work using the opposite - going back to Dalvik, but this seems to have worked, at least for the last 24 hours.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Gustavo Pinto||2/24/14 2:12 PM|
As it's an intermittent problem, everything we do seems to work until the problem reappears. I flashed stock 4.3 and got the weird battery drain. Now I'm on 4.4 using Dalvik and things seem fine, but I'm sure I'll be complaining soon enough. Since I did not experience the problem for the whole of 2013 on 4.3 and now I see it on that exact version, I think I can rule out core Android. I'm thinking the issue has to be a recent update to bundled Google app, but haven't got a lock on it so far.

I'm guessing its the Google Search app, which seemed to be the culprit when I was having problems over the weekend - just got the phone on Friday - certain wifi environments kill it. It also doesn't seem to like being inside a pocket - gets very hot and discharges quickly.

Have a Nexus 5 and experiencing the same problems. Did a factory reset, but it got stuck at the "Erasing" screen, so I had to reset the device manually and flash the stock 4.4.2 ROM back on. Still experiencing the same battery drain as soon as I turned the phone on before installing apps. I'm suspecting it might be a specific Google app, which would align with what most are saying here. I considered flashing 4.4 or 4.3 to see if the problem persists, but from what people have said, it doesn't matter which Android version you're using, this problem can pop up randomly on them all. So, I went into safe mode and disabled every application (including Google apps) on my phone, and my battery life improved immediately, however, the (when looking at GSam Battery Monitor) Kernel (Android OS) continued to abnormally suck out around 27%-30% power under the applications when it would usually hover around 10% before I started having problems. So, my suspicion is that what is draining the battery is simply one of the "Google Services," which would be hard to disable without seriously handicapping the smartphone experience. Hopefully someone can figure it out, unless Google fixes it first. I have a feeling that when Kit Kat 4.4.2 came out, Google "updated" some process within their Google Services on each device, rolling it out at different times, and that's why people are experiencing such weird results with no clear answer.
But that's just me...

As I said - switching to ART seems to have made all the difference - things seem back to normal now.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||MikeWelch||2/28/14 8:00 AM|
I did the same thing -- factory reset, disabling apps, etc. It turns out that it's a problem with the OS not being able to work right with certain routers. Turn off WiFi and you'll see the problem goes away. I know it's not a solution, but a temporary workaround until Google (hopefully) fixes the issue.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Micah Robertson||2/28/14 7:10 PM|
The only issue with that, is that I'm seeing the same issue when I'm not connected to wifi and only connected to my mobile data. However, I haven't tried turning off wifi entirely, so I will give that a shot and post my results.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Micah Robertson||3/1/14 5:00 PM|
I tried turning off WiFi entirely and it seemed to not make a difference. My Android OS Kernal battery usage is still around 44% and sucking my battery down like a mother. Anybody have any other ideas?
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Horatio He||3/1/14 5:54 PM|
This mostly happened to the last or some app u installed recently, for me I uninstalled es file explorer then drain is gone. Its quite normal that the apps are not fully tested w the new version of os. Try to reset to factory, install minimum apps then c what will happen, good luck

I'm also having problems with my battery life since the last Android update. Now I cant even rely on the alarm when I go to bed, everything is off, wifi/bluetooth etc but the phone justs die in the middle of the night.
Before the last Android update I hade perfect battery life.
If I reset my phone, do I lose all my pics, contacts etc!? Never done that before.
If someone knows another solution please let me know.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Horatio He||3/2/14 3:26 AM|
Set Google auto back up on ur phone, if u r not comfortable, export all contacts and back it up manually to Google account, copy ur pics out. Then u have choice to flash back to 4.4 or reset to 4.4.2, and install minimum apps then test
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||ksobier||3/3/14 6:44 AM|

|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Aref Azmi||3/3/14 6:54 AM|
This will be my last solution. I've done the ART thing since yesterday, and that maybe helped me with 5-10%, bit its still pretty bad battery time, compared to what I had one month ago. I had 99% battery this morning at 8'o clock. I've only used the phone during my lunch break which is 1hour.. Now I'm down to 10% battery left.. And this is with the ART-mode.
Just one question.. If I reset the phone back to the earlier version..will that affect my phone? Considering the previous update which improved the camera?
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Micah Robertson||3/3/14 10:07 AM|
Yes. You are fundamentally installing a completely different OS, which would mean that the camera would back to it's usual quirkiness and any other issues you may have had before could show back up. You will have to completely wipe out all the phone's data to install the 4.4 OS as well, so be sure to backup your apps, settings, etc.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Ed Chavez||3/3/14 10:13 PM|
I just installed the KitfKat 4.4.2 update on my HTC One Tmobile the frustration has been endless it drains my battery so fast and my OS is at 97 percent what the heck!
I have done Factory Reset, Safe Mode, Uninstalled Apps, Clear Cache through System Reboot, Calibrated the Battery Via Holding Power and Volume Down Button (that feat actually helped a little but the OS still drains it fast) what is left to do I am at lost. Is there a bug that google hasn't attempted to fix what the heck this is horrible.
Have you had any success fixing the issue at hand?
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Micah Robertson||3/4/14 9:36 AM|
Well, it looks like I'm having a little bit of an interesting experience today...
Yesterday I tried booting into safe mode twice. One of the times I booted into safe mode the issue was fixed, but immediately returned as soon as I reverted back to (normal?) mode. I tried booting into safe mode again, and the issue did not go away. Strange.
So let me take you through this chronologically: The time I was in safe mode WITHOUT the Android OS draining issue (miraculously), I looked at the apps that were running. The only apps that were running were Google services. I restarted my phone back to normal, and BOOM, the issue was back. So, I restarted BACK into safe mode, and what do you know, the Android OS was sucking the battery up like a mother again. I looked at the apps that were running and this time, they were still ONLY Google Services. I even looked and compared how much RAM each Google service was using compared to before (when the problem had resolved itself) and there was absolutely no difference.
So, feeling hopeless, I figured I would put my phone into Airplane mode last night while it was still running (I left it plugged into the charger, putting it into Airplane mode during the night is something I never tried). The next morning I wake up and head out the door listening to Google Play Music. An hour later I look at my phone to check out the battery life and what do you know? It has ONLY drained about 4%-5% within an hour (usually it would drain down to AT LEAST 75%-87% within an hour's listening to music, this time it was chugging through at 95%!). So I check out the battery stats, and within the Kit Kat settings, my Android OS is only draining 6% of my battery in an hour's time. I check out GSam Battery Monitor, and the Android OS is back down to around 20% (usually it would hover around 30%-40% when listening to music).
Right now I have absolutely no clue what is going on. The only thing that seems to have made any difference is me putting my phone into Airplane mode over night. What I'm thinking, possibly, is that there was a process getting started while the phone was attempting to go into deep sleep during the night, and for some reason, this process was bugged, causing the phone to drain like crazy. Considering I had already factory reset my phone and the issue persisted before I even updated any Google apps or installed ANYTHING, I have a feeling it is not an issue with any particular application, but an issue, specifically, with some Google Service (like I had been thinking before in one of my earlier posts).
I think we can rule out factory resetting the device, uninstalling apps, clearing cache, rebooting, and maybe even flashing back to STOCK Kit Kat 4.4 to solve this problem indefinitely. I also don't think this is an issue that is only happening with the Nexus 5, but an issue with a lot of phones that have updated to Kit Kat. I have taken screenshots of every application that is currently running now (the cached ones as well), and also monitored the last time Google had updated its applications automatically on my phone (it had not updated any applications since I had unplugged the device). I have a feeling the problem lies SOMEWHERE within there. I even took screenshots of each and every process within the android kernel (looking at GSam), just in case.
I'll update everyone with my results tonight. If the problem pops up again, I'll be sure to record any differences anywhere to see if I can narrow it down. Let's hope and pray we can figure this crap out! Of course, unless Google fixes it first. ;D

|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||MikeWelch||3/4/14 5:39 PM|
I don't think so because from those screen shots, you can clearly see the camera app at the top of the battery list. The issue we are having is with the "Android OS" (kernel) process.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Micah Robertson||3/4/14 9:13 PM|
Okay, I'm back.
So, the Android OS drainage popped back up around 1:00pm-ish and continued on for the rest of the day. I compared the list of apps that had been running before the problem came back to the list of running apps after the problem arose, and noticed that the only other app that had started itself and continued to run was Google+ even though I had never touched it. I looked, and it seems that it had automatically backed up all of my photos over wi-fi around 1:00pm-ish on battery, even when I set it to only back up my photos when plugged in (which it never was plugged in when it backed up the photos). I uninstalled and disabled Google+ entirely, but the problem still seemed to continue for the next twenty or so minutes. So, I enabled Google+ and updated the app back to normal. I screwed around with a ton of different sync settings, disabling apps, etc. and found nothing that would lead me to believe it is any other specific application causing the issues. The only possible culprit seems to be Google+, possibly running in the background, causing a bug in the Android OS that continues even after you uninstall and disable Google+ entirely. That's the closest I can get to anything that makes sense. So, I'm going to try to disable all Google+ sync settings tomorrow, and completely disable the app entirely (and also keep my phone in airplane mode tonight) and get back with you all tomorrow with my results.
And about that qcamera process bug, I had started experiencing that the past few weeks as well, when these issues with the Android OS began, so who knows, maybe they're somehow related. At least Google is acknowledging it.

|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||MikeWelch||3/5/14 10:57 AM|
Not sure if it's related, but your "mobile network signal" dropped at the same time you opened Chrome.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Steven||3/5/14 11:12 AM|
Does anyone know what the sensors.qcom setting is in Vincent's screenshots? Whenever I get the Android OS battery drain, that sensors.qcom process shows up to. When the battery drains normally, the sensors.qcom does not show up. I've googled it, but couldn't find an answer as to what it is.
I have a feeling that Android OS and sensors.qcom are related somehow and if the sensors.qcom process can be averted, the Android OS battery drain will stop.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Vincent Guillou||3/5/14 11:24 AM|
I don't think it is related to the network signal. As you can see on my screenshot, the drain stopped after I closed Chrome while the signal was still similar. I switched to Opera since that day, and I didn't notice any abnormal drain while idle.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Micah Robertson||3/5/14 3:31 PM|
I just deleted and disabled Chrome on my Nexus 5 to see if it makes a difference. Tried it with Google+ but didn't do a thing.
I haven't seen the process "sensors.qcom" pop up when I had the Android OS issue.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||xstrm1||3/6/14 7:04 AM|
Me too. I've always praised Nexus 5 for it's outstanding ability not to drain battery when it's idle.
Just few days ago, I started noticing this behaviour. Android OS eats all the power and I can't stop it.
Yesterday I did a Factory reset, but there's no change.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Daniel Heise||3/6/14 11:45 AM|
My Nexus 4 is also suffering from this Android OS drain. I've contacted Google last week an they send me a brand new device for exchange. But the new phone also suffers from the enormous drain.
I've contacted Google again and ask them if this is a software problem in 4.2.2.
I've got no answer to my question. The Google support only offers another exchange due to the 'defective battery' in the new device.
I've decided to keep my current device and wait for some fix in Android.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Vincent Guillou||3/6/14 1:06 PM|
Indeed, now I always see "sensors.qcom" in my battery stats whenever "Android OS" is draining my battery...
I wouldn't be surprised if our issue was closely linked to the "mm-qcamera-daemon" one that some users are experiencing.
A global problem with the usage of Qualcomm's drivers ?
I sort of hope so, that could mean a fix with the next update for us too...

|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Micah Robertson||3/6/14 7:10 PM|
So here are my before and after results of removing Chrome from my phone (the 14hr day is the day where I was using Dolphin instead of Chrome). It seems to have made a slight difference, but still kind of hard to tell, considering the usage between today and yesterday was a bit different (I used it less today).
It seems like the battery keeps acting like it's supposed to early in the day, and then in the early afternoon, it begins to drain like crazy again during "sleep." Battery stats in Kit Kat settings says Android OS is 17% and Android System is 11%... Gsam says my Android OS is draining at around 28% of my total battery, and out of all my apps, is draining 50%. Gonna install Chrome again tomorrow and see if it makes any difference for me. If it does I'll report back, if not, then I won't.
I'm kind of losing all hope here, I'm really just starting to think that there may just be nothing we can do about it to fix this problem indefinitely... sigh...
Google, hurry up with 4.4.3! Please!
In the meantime, I'll be waiting on my 3500mAh Extended Battery Case to come in. :P
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||e_lizzle||3/7/14 3:42 PM|
I want to thank you! My Nexus 7 has been burning battery while not in use, so bad that I don't even use it anymore. I've been following all these threads about poor battery life, mine went to crap sometime last year. I used to be able to leave the device idle for weeks and now it's dead after a few days. Well, turning off Google Now is exactly what fixed it for me. Battery consumption went from 17% per day to 3% per day. Also, the Android OS process is no longer the highest consumer of power, the Idle process is. Thanks, man!

I'm having the same issue now. Yesterday, the battery went from 97% to 66% in 4 1/2 hours with 22 mins. of screen time. 50/60% of the battery use was from Android OS. This makes the phone almost unusable. I see it´s happening to a lot of people... Google should get this fixed. I have been uninstalling apps to see if maybe one of them is the problem but is too soon to tell.

I have the same issue... "android os" going crazy without reason.... and I noticed that sensors.qcom is always in my list when it is happening. I'm on stock and I made a clean reinstallation of the OS, and I installed only half of my apps... and the bug is already back ! It can happen on WIFI or HPSA/LTE, so I'm trying to find what app is starting this issue (Don't get me wrong, the bug is probably on the google side , however, I'm sure there is an app starting it). Yesterday I uninstalled Greenify (I only had 2 apps greenified) and so far so good ... not sure if it is linked yet.

|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Steven||3/11/14 9:33 AM|
I forget if I had read it here, or another forum, but I may have found a solution. At least for me that is. Someone had mentioned that the Android OS battery drain only occurred when they were connected to the 3G network (whether wifi was on or not). When that person switched to 4G, the issue went away. I usually kept my phone on 3G (ironically because i thought it would save battery power), so I decided to switch to 4G permanently and see what happens. Well it's been 7 days and I've only had the battery drain once. And that once was because there was no 4G signal where I was and the phone automatically switched to 3G. I've been using my phone like I always do, kept my wifi on most of the time, no disabled apps, and used the camera occasionally. The only thing I did differently was I always tried to make sure all my recent apps were swiped away.
I don't know if this is the solution for everyone, but if you keep your phone on 3G a lot, make the switch and see what happens. Although I'm pretty sure I've jinxed myself, give it a shot with your phone.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Aref Azmi||3/11/14 9:38 AM|
That doesn't seem to be the solution for me since I havet used 4G all the time besides when I'm at home, then I use my wifi ofcourse. I really hope Google comes with a solution soon because it's pretty annoying to recharge the phone 2-3 times Evert day since the 4.4.2 update. It feels like I'm having a iphone, and that sucks even more, because even the iphone has vetter battery time than what de are experiencing right now.

I think its safe to say Android 4.4.2 and Stock Image. Rooted vs Not Rooted doesn't seem to matter.
Honestly though, try switching to 4G if your phone is always on 3G
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||MikeWelch||3/11/14 12:25 PM|
So it seems that being rooted isn't necessarily the issue. I'm pretty sure it isn't any particular 3rd party app because I've flashed back to stock and have even tried safe mode and the issue still exists. So it's either a built in Google app or service, or an OS component.

How do you set that? Under Settings > More... > Mobile networks > Preferred network type, I have LTE, 3G, and 2G. I have mine set on LTE, but T-Mobile does not have LTE in my area.
|Re: Battery drained by "Android OS" since 4.4.2 update on Nexus 5||Steven||3/11/14 12:38 PM|
You are correct. That is how you switch. But if you don't have any LTE coverage and are stuck on 3G, then you're unfortunately SOL. However, at least your situation doesn't disprove my theory.
