[Q] Battery drain of nexus 10 android 5.1 - Nexus 10 Q&A, Help & Troubleshooting

I upgraded my nexus 10 to 5.1 and recently I have been exprencing some battery drain
In the morning I leave the tablet on 90% and by evening it is 53% and in the battery menu it shows 23% consumed by android OS. I didn't even used my tablet even once

I have the same issue. Is Android OS always keeping your device awake? I tried a factory reset and no change. Anyone have an idea? Could it be an app doing this when Android OS shows as the culprit?
I assume moat people does not have the issue...

You may use any wake lock detector to see which application wakes up your device. Then you may disable them or use greenify if younare rooted.
Most likry the culprits are google plus and few others gapps that comes with.

Will try that. Thanks!

Note 3 | 4.4.2 version|battery drain of 22% overnight.

Hello All,
I'm using note 3 France version. I notice that overnight my phone is getting, yesterday night my phone was charged till 93%and i closed all the running apps & when i see this morning, am left with 71% of juice.
Stock Android + no root.
When i look at the battery graph, it just says "android os" for 100%.
Is it actually hiding any of the background process?
Is this normal?

In my case, the sd card is the culprit. Every thing back to normal when i remove the sd card.

SD card shouldn't be a problem, many people use them without any issues, you may have experienced indexing bug, some program residing partially on a card got shot down, when card was removed, or something of this nature.
As far as OP goes, even battery display itself is weird, never seen anything like that. On mine Android OS, Android System, cell standby, device idle, something from Google and screen will show up at the minimum. In your case it seems every other battery usage had to be very small, way less than 1%, If you press on Android System, you will get more details, but no matter what I would do full factory reset to start with, since neither 22% idle discharge nor battery display is normal. Just make sure you have full backups, since you'll loose all settings and need to reinstall all programs.

Note 3 battery drain problem Solved...
Hi all..
I am using a note 3 LTE N9005. I was facing the battery drain problem with my phone it used to drain at a rate of 10% an hour even when the phone was locked and kept idle. Like some one mentioned above if I kept it aside after full charging in the night it would be around 50% in the morning.
Then i installed wake lock to check what was causing the issue but couldn't find anything unusual.
Later i noticed that my android system and android OS were consuming more than 35 % charge everyday. Even wake lock and other similar apps couldn't find it.
Finally....finally i decided to uninstall few apps one by one and check if anything changes..... and yessss..... i found it.... Facebook app and Facebook messenger were the culprits. ... particularly Facebook app.
Now without them... i am getting a full 6 hours screen time and 24 hours on normal usage. Just try it.... its worth a try.
Please note : My phone : N9005
Android version : 4.4.2 KitKat
Hope this help you.

Android OS Wakelock killing the battery!

Hey guys,
I've been having an S6 Edge+ for a couple of days already but there seems to be an issue with the ROM. I'm getting a lot of battery drain from the "Android OS" and I'm losing up to 5% - 7% per hour in standby.... I have even re-flashed the entire ROM and factory reset two times... still the same.
I've disabled Google's Location History and Google Now but this did not help...
My previous Galaxy S6 was also running the latest ROM but there were no such problems...
Has anybody else experienced such an issue and do you have any ideas?

Check if any sync is stuck in loop, sometimes this kills battery very easily. If all else fails check with some app like GSam.

Unfortunately GSam does not produce too detailed information without Root access and it only says Android System and lists all the services that are under it...
The interesting part is that after several re-flashes with the same firmware, the wakelock disappeared...
Now I get 76% to 80% deep sleep...
Go figure... Probably some stuck sync as you mentioned...

Android OS Wakelock killing the battery! ...... solved
OK, im not too savvy with settings and systems, just sharing what i have been through. I too had a major battery drain problem on my S6 Edge+ , giving me abt 8-10hrs of use after a full charge. Even during the nights with everything off and power saving enabled i would lose abt 50-60% battery over 8 hours. ..... caused by Android OS ....... it would keep the screen awake for hours even with the screen off .... ( dont know how that worked) ..... tried a factory reset but didnt help. Then rooted the phone and downloaded wakelock detector and installed it as a system app. Installed greenify and doze ..... last night lost 4% over 11hours with wifi and 4g off and power saving enabled which is a drastic improvement. Facing one little problem that images do not get downloaded (automatically or manually) in whatsapp with wifi in use. Will use the cell for a few days and post again abt how the battery is holding up and if there is any other performance issues.
If you want to save battery, try this app:
https://play.google.com/store/apps/details?id=com.kunkunsoft.packagedisabler
It show all RAM usage of each app, you can disable any app in Bloatware (samsung default app) list to save power
This app run WITHOUT ROOT

Massive wake lock and battery drain

Hi guys,
I have been having an issue with my Motorola X Play (UK Single Sim) I have only owned it for a few months from new.... The battery is draining fast and I can see in the battery stats that it's not sleeping, otherwise the battery usage page shows nothing of interest, apart from perhaps Mobile Standby which is quite high, above the screen but the signal bar is all green...
I rooted my phone to better find out what was causing these issues, otherwise stock Marshmallow. Unfortunately Motorola now are not interested as they say my phone is rooted and now has no warranty - useless idiots!
Using GS Sam battery monitor (rooted) I can see that the following is keeping the phone awake, no other app is.
48.3% of battery consumed by Kernel (Android OS)
Keep awake over 2 hours
CPU usage 59m 53s
Number of Wake Locks: 1
Byes sent: 246.21KB
Bytes Received: 5.70MB
App UID: 0
Wakelock Detail:
Google_C2DM 0.0s (1)
I have tried safe mode but it appears to be the same, I have hardly any apps installed apart from Facebook and Facebook messenger and I have even tried it without them...
I have tried turning off/on WiFi / Location / GPS is now disabled. WiFi Scanning is off. Restarts make no difference... I have even done a factory reset about a month ago.
Any ideas, this phone is having the same battery life or less than my Nexus 5 which had a much smaller battery...
Many thanks
here's a way to avoid it http://forum.xda-developers.com/galaxy-s2/help/google-c2dm-checkin-services-t1321520
i'll update if i find anything else.
don't tell them your device is rooted. if you go to service center just re-lock the bootloader and its back to normal.[it won't get your warranty back but they don't check that much]
can you post a screenshot of gs sam.
1 - Install BetterBatteryStats (BBS) - this will give you detailed information on what is draining your battery. Get it from XDA v2.2.0.0B6 - this gives you the detailed breakdown in the UI that you are after, the google play version doesn't do it in the UI (older version).
Get baseline results (charge it full, don't touch it for 5-6 hours) I like to do this while sleeping.
2 - Install Greenify (you don't need the Xposed module if you don't want to fiddle with that yet, alto I highly recommend it) set the working mode to root. If applications are still not sleeping, add the widget and force sleep everything before you turn off your screen
Get BBS results (do the 5-6 hours while sleeping) - improved?
3 - Install Naptime from the google play store (by Fransico Franco)
Get BBS results - improved?
Getting anal about battery usage?
4- Read up on Amplify - this yielded even more results for me. But this can take a bit of work to get right. There's a lot of great threads on XDA for setting this up.
5 -Smart network - allows you to control data, networks, wifi, bluetooh, nfc, gps on/off with a ton of great features for auto. management.
I have all the above and yield a 0.4%/hr drain on stand by (see signature for phone build).
Amplify is a god sent app. It has been 4 hours now, and I have been using whatsapp on and off (about 20 seconds each time) and I still have 97% left in the tank.

Facebook app has been known to cause serious battery drain in the past. Uninstall it and test again.
In 99% of the cases it is caused by an app. Try to find out which one is causing the drain.
Hi all,
Sorry for the delay and thanks for the replies. I performed a factory reset again, after clearing the cache etc, the same as I did last time. The only difference is I then installed Android 6.0.1
The battery drain has now gone. I didn't perform a restore of apps etc, and the only apps I have installed so far in addition have been Facebook and Facebook messenger but I have found these have had no effect at all on the battery drain. I haven't even updated the stock apps (apart from the security ones).
I now get two days of use easy. It also seems to be running slightly faster. I will update apps one by one, over the course of a few days to make sure nothing causes it again...
http://forum.xda-developers.com/android/general/guide-extreme-battery-life-t3095884
I use this guide, works really great to limit wake locks.
And I don't use Fb app but use the browser instead, battery lasts easily two days of "heavy" usage !
I found the problem, or at least a major bug. Whenever you cast to Google Chromecast Audio and then stop casting completely there is a massive wakelock until you next restart the phone. My phone was awake all night and down to 20% battery life. Android OS takes a massive portion of the battery life and under keep awake stats it's 9 hours +. It seems that when it says disconnected it is not. A major bug! I'll try and report it using Google's bug reporter...

not even Doze could kill it? perhaps you could try Servicely and see if it could stop the thing from running.

Nope, Doze had no affect at all but it should be as it was sitting stationary overnight - normally the drain overnight is a few percent at the most, last night it was around 65% and I was left with 20% in the morning and this was I think the first time I had used Google Chromecast Audio since the factory reset with great battery life up to last night... I could try Servicely but I am not sure on the service to kill and I'd like to keep it 100% stock for now so I can help out Google to fix the bug (or Motorola if they bother)... What a pain as I just bought 4x Google Chromecast Audios!!
I have reported it here in the Android bug tracker, feel free to comment / star the issue to bring it to Google's attention.
https://code.google.com/p/android/issues/detail?id=208324
However I am not sure if this is a Motorola Issue or a Google Marshmallow / Chromecast issue?? Motorola support have been very unhelpful so no luck if that is the case...
If anyone else with Chromecast Audio could confirm the bug that would be great.
Thanks
Laurence
There's a post on reddit about battery drain with chromecast audio about a year ago, not sure if it's the same issue though.

Note 4 stays awake and drain battery while idle

I am using Note 4 (N910C) bought new 4 months ago but some times device behave weird. Sometimes device stays awake (cpu stays active) while screen is off and the device is not being used. When this state happen in the battery stats it can be seen that the awake line becomes strong and permanent and only solution is to restart the device.
After restart, device behaves normal for about 2 to 3 days and after that same problem persist. During this situation 4% per hour battery is consumed when device is idle.
In battery stats Android System and Android OS consume most of the battery when this problem happens. Otherwise device consume normal battery and I get about 6 hrs of screen on time.
I have tried several solutions like
Cleared cache.
Disabled some pre installed apps which i don't use like svoice etc
Disable sync services
Installed Gsam battery monitor but no-special process found other than android aystem which consume battery in problem state.
But nothing mentioned above really helped. The only known solution is restarting the device which help for like 2 days and problem comes again.
Device is not rooted and I am using original Samsung OS. Lollipop 5.1.1 and Marshmallow 6.0.1 both have same problem the later was updated via OTA. But nothing addressed the problem.
Please guide with the possible soultion?
I have the exact same problem, would be great if somebody can help
Sent from my SM-N910F using Tapatalk
I also have the same problem, i'm going to search deeper in the forums if someone solved this months ago
So far it ends up wasting the battery of a generally idle device and stays up long enough for my screen and body to heat up when left unattended.
Have you already fiddled with the screen settings itself? Particularly Settings>Device>Display and Wallpaper > Smart Stay? I turned mine off and it did reduce some of the battery drain issues.
WiFi and mobile data (even just the plain mobile signal) seems to drain the battery too a little quickly.

S4-i337 battery drain via Android OS

Hi there, for the last week or so, with no new apps being downloaded prior to issue, I have noticed a significant battery drain by Android OS (39%) and inside it showed incredible Keep awake time of 16h 50m (though the phone screen is off). For reference, the screen time (25% battery usage) so far is 1h 31m. I have installed and given root access to GSam Battery Monitor (its root companion is activated too). The program indicates that Kernal (Android OS) is taking up my space but I was hoping instead it would be able to give the direct app that is eating up my battery. I have tried restarting it twice and after letting the battery run off completely and fully charging it before turning it back on.... no dice.
S4 - SGH-i337M (jfltecan/jflte)... verified root... Android 4.4.2
SlimROM-4.4.2.build.4-OFFICIAL-3650
Build number: slim_jfltecan-userdebug 4.4.2 KVT49L 3650 test-keys
Kernal: 3.4.82-KT-SGS4-gb0a91ad
Recovery is via TWRP
I know there may be suggestions to turn off GPS, WiFi, etc, etc... but I'd rather not do that due to the fact the phone life was absolutely fine w/ them on... I'd like to fix the root of the problem instead of working around it. I haven't made any changes to phone settings for a month. Reformat is a last resort but want to exhaust options prior to.
Any help appreciated, thanks.
It seems that the only way to have figured it out is by disabling individual apps and see if there is any improvement in battery life and drop in Android OS wake time and battery use.... After checking the 4th app of possibility, it seems like KiK was the culprit. Just going to remove the app as I haven't used it much. Maybe an update for the app occurred causing this to happen. One work around for those who want to keep the app that's causing the issue and minimize the battery drain, you could just go to the app's system settings and do a Force Stop and the program will be off and then turn the app back on whenever you need it and then turn it off again via Force Stop. It's a app issue, not anything you can really do about it except downgrade or uninstall the app.
