[Q] Android OS Battery Drain

In the last few days, I have noticed that the process "Android OS" has been using maximum battery life (about 16-35%) and has also been consuming large amounts of data.
The only thing I have done recently is allow the facebook app to upload all pics from my mobile.
Any connection? FYI, I have not added a Samsung account.
Apologies if this has been answered earlier by I did search for it.

what version of android are you running?
what ROM? what kernel?
how long ago did you start to notice this?
is it a constant issue, or does it fix itself after a reboot or something, or with data connection turned off?
do you use google now?
if you are on the jelly bean 4.1.1 version, did you update OTA or odin? just curious, probably not related anyways...
what recovery are you using?
just trying to get some info before i help. many things in the android OS can be directly or indirectly related to each other but still have a side effect on battery life.

16-30% in general has been relatively normal on JB. (Usually between 14-18% is where it settles to)
Keep in mind that unless you are at least halfway through your batt cycle its going to be higher. If you're at 90-95% batt it can be much higher, just due to percentages and battstats being reset.
Not sure why you didn't find anything though, this has been covered a great many times in the past 6 weeks! Did you look at what the top processes are under Android System?

I had installed root66 prerooted JB rom. When I noticed the problem, I installed stock ICS through odin, updated to stock JB then rooted again but the problem continues.
I have been noticing this for about a couple of weeks. Restarting doesnt help but I havent yet tried turning off data. Will try that and let you know.
Yes I use google now.

Is this something peculiar to JB? I didnt see this in ICS. The top processes currently showing in the battery stats are Android OS: 28%, Voice calls: 17%, Screen: 11%, android system: 8%...
Is there anyway to check exactly which app is using the battery and data which is showing as Android OS?

Odd... mine is usually only around 10%

Mine generally sits between 11-14% depending on use. But it can show 30+ if you check it at certain times.
For example, if you've fully charged the battstats will have reset. If you reboot the phone it will kick off the media scanner which can run for a while (this can also be the cause of it heating up for a short time). So once its complete it will have used a rather sizable chunk of the overall battery use. Since it usually doesn't run again, the percentage will steadily drop as other processes use the battery.
I know we aren't really discussing the media scanner, but I use it as an example that is pretty easy to see if you watch it.
Android system has a lot of processes which are listed under its category so depending on how each person uses their device it can vary a bit. Most screenshots of 'normal' reports that I've seen usually are around 14-18%. For me its lower, but I'm pretty sure I don't use mine the same way others do. There are times though where it can go higher for me, depending on what kinds of stuff I'm messing with or testing out.
I believe transferring large amounts of data over mtp is one thing that can cause it to go up...
Hope that makes sense.

my phone just started this last night. i took it off the charger around 11 last night (100% charged) and it woke me up at 3:30 with a low battery indicator, i checked task manager and nothing was open battery stats showed that android os was at i think 38%. i put it on the charger this morning at around 9 am because it had died fully. it's now 1 pm and it's at 95% charged, typically it takes only a couple hours to charge. my phone is fully stock running jb.

What kernel/ROM and version of recovery are you using?

You can track data consumption of Android system apps via Droidstats
You'll be able to know wether it's Google Maps or any other service that uses data

I am fairly confident I've tracked it down to the touch sounds. Sounds dumb I know, but I believe they are wake locking excessively. I have much better results with ANDROID OS drain with them turned off. Interested to see if others do too.

Hey there,
im having a similar issue with my Google Nexus 10 running stock Android 4.2.2 (fresh install of factory image and then manual update with ota update.zip).
Here are two screenshots (didnt want to include here because they are HUGE and I dont know how to resize them in forum "code"):
One
Two
I havent been using it much the last days and im a little spoiled by an iPad 2 standby time so this is not very acceptable
I'll try Droidstats and see what I can make out of it.

Looks like you haven't used the tab (screen time) that much over the two days, making Android OS seem overtly guilty.
Try disabling touch sounds -- settings-sounds- touch sounds
Then let us know. I am convinced that is the culprit of the wake locks, keeping the Android OS (kernel & drivers) high and eating battery.

Sorry, forgot to mention it. I have them disabled since i own this tablet (and I checked it again).
I wanted to try DroidStats, but it seems to be an app for calls, sms and data
Can you post a link to this app (if its allowed )
EDIT:
Yesterday a friend of mine showed me the battery stats on his Galaxy S2 and had almost 40% "Android OS".... but he has never had better battery life. I start to think that (because of the percentage system) the built in battery tools are almost useless
Is 4 days a normal standby time for the Nexus 10? That would be very bad in my opinion.

I've just started seeing the same thing with my Galaxy S3 (Samsung issued ICS, rooted). Normally the battery will last around 24 hours with light use, but currently it's draining from full to warning level in about 4 hours with the screen mostly off (wi-fi, bluetooth and GPS are off at the moment). Touch sounds have been set to off from day one.
Yesterday, the culprit looked to be Beautiful Widgets (around 38%) so I turned some of that off (weather update animations, etc) but I'm still getting the same drain speed - now showing Android OS 26%, Cell standby 22%, Android System 15%, Screen 11%. Not sure if I trust the results though, the BW issue from yesterday could have been a red-herring.

[SOLVED!!]
i have this problem with my galaxy grand phone ,the battery discharges in 20hr , default OS was 4.1.2 official samsung , i changed my rom into a slim custom rom based 4.2.2 , but the battery has same problem again , Android OS battery Usage Was 80% !!!! and screen usage just was 9% !
my installed software :
Viber
WeChat
MyKet {Like Android Market}
Weather Widget
i used wifi 1-2 hour in a day ,
=================================
[SOLVE]
first go to Settings -> Developer Options -> Apps Tab -> checked Don't keep activities
set brightness to auto
then go to location services -> off access my location
then go to wifi -> advanced Wi-Fi -> keep wi-fi on during sleep -> change to Never
now go to application manager -> Running Tab -> Force stop some apps with extra ram usage like settings
my phone just uses 5% battery in 13hr sleep mode ; ENJOY!

I have tried doing partition wipe cache and disabled most apps under auto start manager, unable to figure out what is causing this issue
I have no other issues on Asus Zenfone 2 and it is probably the best Android phone I have ever used, just this battery drain issues is irritating.
Lot of Zenfone 2 users have logged this issue on Zentalk forum but Asus support seems to be clueless about it, recent firmware update also failed to address this problem.

I think it depends on wi fi...
When I'm at work ZenFone connect to various AP and the battery drain is heavy....
But when I'm at home the battery seems to be normal, I can finish the day with 20% of battery from 17 to 21.
I see the battery is longer on 3g/4g than when i'm at work on wi fi

I think Zen Motion in settings specially touch gesture is one of the causes for battery drain issue...
Sent from my ASUS_Z00AD using XDA Free mobile app

Probably...but when I'm on 2.17 I don't see this battery drain....and I always have gesture, double tap to wake/sleep and zenmotion all gesture.
I see the battery drain increased when Asus have changed power profile

'Wifi Scanning always available' may cause battery drain. Recommend to turn off in not needed. To do this go to Apps/Settings/WiFi Settings/Advance Settings(menu in upper right corner)/Scanning always available/ turn Off. If battery still draining, recommend updating firmware to latest version and then performing a factory data reset. Please ensure to back up all important data as this will erase all data.

Hi Frank,
Regarding the Wi-Fi always on thing... Whenever I turn it off of always turns back on automatically.... Any advice.. I already am on 2.19 BTW..

Apologize for the delayed response. Strange, it shouldn't turn back on automatically. After latest firmware is applied, recommend doing a hardware reset including wipe cache partition. For hardware reset/wipe cache partition instructions please see the following: http://www.asus.com/us/support/FAQ/1011956/

Frank have you heard any rumors on if asus is working on the 5.1.1 update. The issue of Android us chewing up battery is a widely known issue for lollipop 5.0 and it impacts many different devices. Every thread I have read regarding this specific issue states that lollipop 5.1.1 resolves this issue.

Pathetic battery back up on ZenFone 2, hardly getting 3 hours screen time these days
Sent from my ASUS_Z00AD using Tapatalk

My battery stats still reporting WiFi use when I have turned WiFi off and disabled always scanning. I don't get it!?
Edit: just figured this mystery out. It's because I had location set to high accuracy. If you set it to high accuracy or battery saving it scans WiFi even when WiFi is off. Put location to GPS only for the last ten minutes and voilà - no WiFi use in the battery stats

Spoke to soon, WiFi came back again on battery stats!???

Do you see any major results with that application?

I read a lot about awful battery and screen on time before buying the zenfone 2. Surprisingly though with a bit of tweaking this has been one of the best phones I've owned in terms of battery life. I could have easily gotten 10 hours of screen on time i believe if I stayed in an area with stronger reception and turned off some background services like GPS. Here's some screenshots for anyone interested

I'm using the 551 with the latest .22 update. I'm not sure *exactly* what I did to fix the idle Android OS battery drain but I have underclocked to 2.0ghz, zen motion stuff is turned off, GPS is set to battery saving mode, all the stuff under Google settings >security is turned off, Asus cover off, detect battery draining apps in battery settings is off (its not very efficient as it just checks what is running in background, regardless of battery usage) and some more stuff that I can list later on when I have access to my computer

hmm, Well for screen on time Underclocking should help the most. If you don't do any heavy gaming you can set it down to 1.8 without noticing a performance hit ( you could probably take it down to 1.5ghz but I haven't tested that thoroughly so there could be an impact). I use noop as the I/O scheduler but that probably doesn't make a difference. I don't use greenify but I do use servicely. I also stay far away from facebook and the messenger app as that has always caused me crazy battery drain but I know those are apps alot of people would rather not delete so its up to you. I use balance mode in power saver and also use Asus' built in auto start manager to disable most things at boot I don't need. Another thing that helps with wakelocks is to make sure you open the google settings app after you boot ( you dont have to do anything, just open and close. I don't get it either) it works for many people including myself.
Other then that I can't think of much else I do. If anything else comes to me ill be sure to let you guys know

Terrible battery life (H815, 6.0 Marshmellow)

Hi all,
I've had my LG G4 since September, and it's been a good phone. However, more so recently, the battery life has been terrible. When Doze decides to work on my phone the battery life is average, but it rarely seems to work. I use over 60% battery in 5 or 6 hours, and that's with most of the time the phone screen being off.
For example, tonight I went to see the new Star Wars film. Using that as a guide, my phone screen was off for about ~3 hours during that time. However, see attached, the battery is just being drained. There aren't any particular apps that I see using 90% battery or whatever - in fact, using a battery app, it looks like phone radio is using an incredible amount.
i.imgur.com/MCQ6Yz0.png
i.imgur.com/ziZEoEz.png
i.imgur.com/a8J9ufZ.png
Any tips for increasing the battery life? I don't see myself as an over user, but I often come out of an 8 hour work shift with just 20% left, and that's with mild web browsing every now and then, and maybe 20 minutes of YouTube video.
I'm thinking about doing a full restore on weekend after backing up my texts, or even ordering a new battery, but I don't feel this should be necessary.
My screen brightness is always 30% or lower. I don't know if this would have damaged the battery, but I use an Aukey quick charger.

-since how many days are using marshmallow ??
-What version ?? V20B or V20A ?
-Did you do a full factory reset after upgrading to MM?

Thanks for replying.
I've been using it for 16 days now.
I updated though LG Bridge, and software info says V20a-EUR-XX
I've not done a factory reset, no. Will that help? All my photos, music and contacts are on Google's servers so I would just need to back up SMS and a list of apps.

Thanks. It looks like my SMS are already saved to my SD card, so hopefully they will work straight away.
I really hope a reset fixes it, as I heard such great things about the LG G4 battery (with people posting it can last 24 hours or more!), and this is very disappointing. I'm off this weekend, so I will do it then.
If anybody else has any fixes as well, I would love to hear them if this doesn't work! The phone is great so far... aside from this.

Sent from my LG-H815 using Tapatalk

you have a rogue app or something, there is nothing wrong with Marshmallow 20B (or 20A for that matter) and battery life. I get insane battery life on this phone, often 22 - 30 hours of fairly heavy use.
Now granted, my phone is rooted, bootloader unlocked, running stock 20B and I have installed a couple of apps to optimize it such as AdAway, LBE security, and KinScreen, but still, you have a misbehaving app most likely that needs to be kicked off your phone!

Is there a way of finding which app? Nothing stands out. I've just taken another screenshot (disabling uploads Google Photos didn't fix it)-should screen off be using this much battery?

A reset is definitly in order tomorrow

sure, start with turning on Developer mode by hitting Build Number in rapid succession a bunch of times in Settings ---> About Phone ---->Software Info
then look in the new Developers Options section of Settings and look at Running Services & processes - you can also download an app for this such as Elixir 2
another good diagnostic tool is heat - heat and battery life are proportional, if your phone runs cool, it will get long battery life, if you pick it up and it is warm around the power/volume buttons, then something is amiss - you have a runaway app or process
download a tool like CPU Temp from the Play store and see what the CPU temp is when the phone is idle or you are doing something light like reading an article - it should be in the 78 - 89° F. range (25 - 32° C.) If the phone is not in this temp range, then something is amiss! - Also keep in mind that the main battery drain on the phone in normal operation is the display - keep auto-brightness on, and keep the display off when it is not needed! - also turn off stuff you are not using, such as Bluetooth, NFC, etc.

I did a factory reset as suggested above, and I think it fixed it. I didn't restore my LG backup as I figured that that'd restore the problem, so went through and downloaded apps again. I then left it on overnight.
After 6 hours it was still at 100% on Wifi, which is great! I then used the phone for ~2 hours (apparently pretty heavily) which actually dropped it to 58% - whoops. I then stopped using it again but this time without wifi, and it didn't keep at the same % - it seemed to drop 10% in about 2 hours. The only things I'd changed since then was install Skype (which I might delete if that's the issue), and had it on mobile data.
imgur.com/n58dP1D
Could mobile data REALLY make that much of a difference? I think I'll leave it unplugged again tonight and not on wifi, and see what it does. This is an issue though if it is mobile, as I'm often not connected to a network.

Seems like mobile radio active bug, I have the same problem. While mobile data is active, my battery drains with the screen off. I have this issue since v20a and no - factory reset doesnt help at all...

High battery drain for a fresh reinstall 7.0 in idle for no apparent reason

Hello, people!

about 5% lost per night
WiFi always on, whatsup, maildroid checking one imap mailbox for every 120 mins (set to wake up the phone), ok google OFF, now cards OFF, backup-ing OFF. Steady about 5% (4-6%) per night.
Now, I flashed factory image 7.0.0. everything stock. Then I flashed boot.img with disabled encryption and formated data and cache. Everything is as it is described above expect for the maildroid has NOT been even installed yet.
And that's what I get second night in a row (rebooted, cache wiped from recovery mode before leaving the phone):
23% eaten for doing ABSOLUTELY NOTHING!
What even worse, even android itself does not know what it was doing that it ate so much battery because the percentages does not add up for the whole drain.
After so many time invested into this phone for getting pure stock 7.0 unencrypted I just feel exhausted and want to throw this phone out of the window.
I'd appreciate a right direction for figuring out what drains the battery.

Yeah battery blows with nougat. Significant Google play services drain mainly bet scheduler. Had somewhat similar with MM but was able to really calm it down with Power Nap, bit since Xposed is not out yet for N....I'm nandroiding back to MM too.

I downgraded to MM, and it became normal. The next day I missed the quick switching between the last two opened apps and I flashed N again))
Actually, this night it drained 8% what is kinda OK. What I additionally did was that I disabled under google account sync everything except for the contacts and calendar. Also I activated data saver and added only whatsup there. Wifi was on all night, but he phone did not seem to be waking up during the night at all, what is good because I didn't need it to be doing anything except for idling in case someone calls for emergency. So, I guess after some hard tweaking and disabling things I can cope with N, but mostly for the sake of awesome interface features.

Wifi was on all night, but he phone did not seem to be waking up during the night at all, what is good because I didn't need it to be doing anything except for idling in case someone calls for emergency. So, I guess after some hard tweaking and disabling things I can cope with N, but mostly for the sake of awesome interface features.

Just give it sometime...things are settling in...so a lot of time play services and stuff also go crazy...also apps are getting updated as well...give it a week or so...things will be better

I had this sort of issue on DP5 after a while but clean flashing MM stock and then re-OTAing to N seemed to fix it for me and I'm back at 5-6% overnight.
I honestly think there is a bug in there somewhere, whether its Google services or what i've no idea as my battery stats didn't seem to add up to the drain I was seeing. I had a similar weird drain before on MM too which a wipe sorted out.

give the system some time to settle in. i upgraded to N the day it came out and after giving android a few days i recognize no major difference in performance or battery life, even though things like Force Doze are incompatible now.

Sorry for off topic
How did you get that icon to the left of alarm icon in status bar (circular arc with + sign in the center)?
Thanks in advanced

That's a new data saver feature being turned on. Setting -> Data usage -> Data Saver option there

I went back to MM not because of the idle drain, infact, I had no drain but the SOT sucks... Like 2-3 hours instead of 4-5 on MM. Maybe I'll wakt until Xposed it compatible again...

Hi, I don't mean to hijack the thread, but I posted about an issue with the screen, which is battery related as well. Actually when idle I have almost no battery drain (up to 2% per night). Could you take a look at this thread regarding the issue: http://forum.xda-developers.com/nexus-5x/help/nexus-5x-android-7-screen-battery-usage-t3463591
I have screenshots prepared (even worse than what I've already described), but as already mentioned I don't have enough posts in order to be able to post them here.
Is this an issue with the screen, battery or OS? The device is new with the OTA Nougat update.

How exactly did you downgrade to Marshmallow? I'd like to know because my 5X drains battery like crazy without doing anything on 7.0

Lenovo VibeShot z90-7 battery drain

Hi guys,
I had this phone for maybe 2 months now, and battery really sucks, even though it's 2900 mah.
Problem is following, i cant really identify any issues, i dont see any abnormal wakelocks, or anything that's actually draining the battery.
But still, drain is around 2.5% per hour, on standby, in deep sleep.
If i kill bunch of apps from android system, like lenovo checker, location, etc, it gets down to 1.3%, but comes back up after 10 hours or so.
Phone has stock, international rom, not rooted.. Any ideas?
Here are some shots for reference, after it was left to idle overnight, and even in airplane mode.
Would someone be so kind to attach these screenshots for me? (I can't, as a new user)

On Lollipop roms battery is sucks. On Marshmallow roms are 30-40% better. Flash new rom if you are on LP rom.

So i presume you already have marshmallow?
Can you share your battery usage specs, and how much % it's draining per hour?

But i'm using phone almost all day.
I have 30+ third part apps installed.
If you enable Sync all day battery drain faster than disabled.
When i use phone only when i need, not for YouTube, read news or similar, i dont charge phone before night.
About 15-20% i have 22-23h.
On LP in idle drain about 15% - to much.
On MM almost nothing max 5% for me.
I tested this 4,5 times.

On night, day, or even in airplane mode, i always had 2.5% drain, per hour. I disabled everything possible, but the problem was the "double tap" to wakeup feature. I found it using gsam battery monitor, it showed me sensors logs, and it was always awake. After disabling this, phone finally works normal, i reseted the counter, i'm now on 3rd hour, and still shows 0% per hour.
I'm still thinking about upgrading, i will get it to 100% charged and see how it works then.

Wha rom you use? I also disabled double tap. This feature drain battery, but i have rooted rom and i have much more options in Xposed, SecurityIt for better battery.
If you have rooted rom i suggest you to download PowerToggles app. In app you have feature for enable/disable sync mod.

I newer hear for that rom
Mabey some new chinese ROW rom.
Послато са Lenovo Z90-7

It's stock rom, international version (ROW), no root, has google play, no bloatware, it did come with some malware (teleyphone, and android.v5 sommething) which i managed to disable via ADB.
With phone mostly idling, and a longer phone call, around 1 hour, i used 13% of battery in 20 hours, so i'm pretty satisfied with how it works now.

It's possible, i bough it from tinydeal, chinese website.
I also got previous phone from china, from etotalk, it was p770, with 3500mah battery, it had their customized rom, battery was unrealistic, i got 9.5 days average use.
Here's my battery usage now, on Z90-7
Here's on my old phone, P770, also chinese custom rom, made by the seller.

I had the same issue with android 6.0.1.
The problem is that the location service also uses Wi-Fi and when it is enabled it keeps the cpu in a loop awake and drains power. What you need to do is to go to Wi-Fi settings and disable the scanning for known networks. Then go to location settings and more and disable Wi-Fi and Bluetooth, then go back and choose the option for location as device only (no Bluetooth /Wi-Fi). Restart the device.
If you need to use the location you have to refuse the prompt to improve accuracy. If the battery drain occurs again you just have to disable the settings again and restart the phone. To check for the issue type battery in the search bar and open the 1st result and click on the graph or open it from and app like sensor multitool and open the usage summary. After I did the fix I lose about 1% every 3h with the screen off and receiving notifications. And about 4h of screen on time. The other thing that keeps the phone awake is the function knock to wake, double tap the display to wake up. Disable that too.
