Hello.
Sometimes my phone works normally about 25hours, sometimes it works twice shorter ~10 hours. I've analyzed battery usage and found out that only difference in Android OS process.
25 hours battery usage
Display - 60%
...
Android OS - 4%
10 hours battery usage
Android OS - 60%
Display - 15%
This definitely looks like a bug. OS should not use more than a display.
Is there any way to found out what is Android OS in details?
Why it takes to many power?
P.S. I guess that bug is triggered by programs like Google maps,
but can't definitely confirm it.
Is there a way to shut off maps till needed?
Get spare parts and you can check what is using what. It could also be useful to get watchdog or similar app to check if you have any apps gone crazy. It isn't unusual though that the screen usage is lower if you just haven't actually used the phone that much as the percentage is always 100% and is divided among the things that used the battery, thus the usage percent doesn't imply mA usage.

I have still pretty high "Android OS".
Display 31%
Android OS 21%
I've tryed Spare parts (Battery history), but it doesn't help.
It just doesn't display such name.
Is there any other way to find out whois is lurking
behind this mysterious title?
I'm betting you have a "suspend process" issue.
What does Battery history from spare parts say? Choose CPU usage, Since last unplugged. Is "suspend" close to the top? What CPU usage details does it have (if you select it)? Obviously look at this data at the end of your phone's battery life, before you plug in.
Also what rom are you using? With cm7 it seems that the battery stats are quite crazy and don't seem to add up to the actual usage, it's been discussed a bit in the nightly thread. The inaccurate stats don't explain the changes in actual battery drain though...
just to be sure, you have usb debugging enabled right?
I'm on official ROM (no root) with USB debugging enabled (I confirm init issue).
My last guess that "Android os" caused by "Location -> Wireless networks".
Now have ~2 days uptime without ever running "Google Maps" and with "Location -> Wireless networks" constantly unchecked.
P.S. Spare parts constantly eats about ~3% CPU at top. Too many for battery monitor. Removed it.

Hey, since you're worried about slight additional CPU-usage and overall performance, you really should consider S-OFFing and getting a different Radio and a custom ROM like ARHD. Or at the very least flash a new kernel, Buzz' kernel did wonders for me.
Hi everyone. On Tuesday I recived a brand-new One X. I applied all the updates (it was until .11). It seemed that the battery didn't last a lot, and on the stats it showed a high usage coming from Android OS.
Yesterday I applied the Sense 4.1 update from the RUU, as on some forums I've read some suggestions to do a factory reset. – I've all the default settings.
Today, it happened the same. (I attach some screenshots).
The problem isn't the usage of the screen (14% –*18minutes), instead, it shows the biggest drain as "Android OS" which had a keep-awake time of 5h 16m out of a total 6h 11m of usage.
It has drained almost 4% every minute.
I don't think that the problem is caused by any app, as I have the stock ones and WhatsApp, Flipboard, FB, Twitter, Instagram, Pocket, Evernote and Chrome, yet, I haven't really used them...
Could you suggest me anything to try to solve this battery drain problem? I checked the battery stats thread and Android OS usage is 5–6% on average.
Some app is preventing your phone to sleep, there are 2 ways to find out, start uninstalling apps untill you find the app causing the problem or better reset and install one by one
Hi,
I've further researched and I found a question on Stackoverflow – I can't post links yet – which says that by using the following command
Code:
adb shell dumpsys power
you could see what wakelocks are on the phone.
I've tried it, but it seems that there's not any wakelock:
Code:
mPartialCount=0
mWakeLockState=
mLocks.gather=
mBroadcastQueue={-1,-1,-1}
mBroadcastWakeLock=UnsynchronizedWakeLock(mFlags=0x1 mCount=0 mHeld=false)
mStayOnWhilePluggedInScreenDimLock=UnsynchronizedWakeLock(mFlags=0x6 mCount=0 mHeld=false)
mStayOnWhilePluggedInPartialLock=UnsynchronizedWakeLock(mFlags=0x1 mCount=0 mHeld=false)
mPreventScreenOnPartialLock=UnsynchronizedWakeLock(mFlags=0x1 mCount=0 mHeld=false)
mProximityPartialLock=UnsynchronizedWakeLock(mFlags=0x1 mCount=0 mHeld=false)
mProximityWakeLockCount=0
mLocks.size=0:
mPokeLocks.size=0:
Should the app that created the wakelock be running, or it can also be stopped? Would work disabling an app instead of uninstalling it?
I'm not a Pro in this matter but I had that problem with every ROM I was using ARHD, IC u name it!
I found a temporary solution to that problem. Turn ur phone off for a good 10 minutes. Then u will see it go away completely to 2% or 3%.
Doing this on a 80+ charge does the trick!
I'm using the stock ROM. I will start by using BetterBatteryStats to find any deadlock.
Before using BetterBatteryStats I disabled automatic uploading to Dropbox, and I think that's what caused the big battery drain. Now, it's a very good battery life.
disable auto-sync if possible...
Android OS battery drain on unrooted HTC
I have the HTC one X and unfortunately ive been plagued by issues from day one. initially the issue was with the screen. I raised a ticket and the HTC singapore guys took like 10 days to get it replaced for me. after the 'repair', The WiFi reception wasnt great and there were tool marks all over the body..!.. i raised a ticket again, and this time they changed the stuff pretty quick. I got a new body and they claimed to change the internal boards and stuff.. Well i got my fon back the day before and the WiFi was great. But then came the next issue. The battery drain. and it was the Android OS process which was eating up by battery. I have attached some screen shots.
I read through a couple of posts in Xda and installed BBS. BBS showed a kernal wakelock which was keeping my phone awake 100%..!..
Could anybody help me resolve this issue please?. i have flagged the issue again to HTC, but im just plain tired of the cat and mouse game that i play with the service centre guys..
Also, Could this be a hardware issue or is this just a software issue?.
PS : i have tried factory Reset once and it did not help me.

Could you solve your battery issue?
Same problem here, no solution yet !!
I currently have a problem that "Google services -> event log service" is draining my battery a lot,
I was asking this in another thread about this problem but got told I should ask here in the specific forum for my phone.
I fully charged it during night and at 2:30am I rebooted the phone and unplugged the charger.
Now in the afternoon at 5pm I checked again (haven't used the phone since then) and battery was at 62 %
Wakelock detector is showing an activity of Google-services/Event log service with 1 hour 43 minutes.
Wlan off, 3G on, GPS off, bluetooth etc off.
I disabled all unessesary syncs including google backup/restore, not helping at all.
I checked developer settings for log recording etc.. but everything is off.
It's the international E975 model btw,
I have the same issue. I think i tweaked it too much lol.
Partial wakelocks in BBS indicates EventLogService has been on for 5h.. -_-
Have you done any tweaks to it? I.e: freeze anything from titanium, greenify, etc
This is a result of frozen apps.

hi there
so if i check what apps are frozen and uninstall them, this will get rid of the problem basically, that simple??
It may just cause more problems. The reason the wakelock is even appearing as event log service is because the app is frozen, but causing wakelocks. But wait, didn't we freeze it?.. how can it still be causing wakelocks? Some other system level app is still capable of waking it, so it may or may not be something important.

cheers, actually i have LOTS of wakelock time taken from these 2:
1) Alarm Manager - Android System. this one grows by 5 units every time i unlock the phone and check, NORMAL??
2) Event Log Service - Google Services, this one is a bit more quiet but still growing silently.
Things i have on:
usually sync, but those 2 above grow regardless of sync being on or off, then i have 2 alarms in the calendar, one active and one not and some calendar notifications.
are those responsible? right now my phone is doing around 2% battery use but i notice that it grows very easily, just now i lost 1% in only 25 minutes.
the "awake" graph under battery looks strange.. sometimes it matches screen off (so good), sometimes, it seems to be on, with screen OFF for no reason whatsoever.
any idea?
thanks
First of all I apologize in advance if this is a common problem and I just couldn't locate it, but I have tried searching for this quite a bit now and can't seem to find anything that addresses the problem I have.
I am running my S3 rooted but otherwise pretty stock (4.1.1 - I just never got around to the updates and I am very much a novice at rooting). I have disabled a number of services, apps, etc (with TB) and never really noticed an issue until recently. My android system and kernel usage as shown in GSAM and the built-in stats are top of the list for app battery consumption (screen comes in at #1 overall). I am getting pretty decent battery life I think but I am in the process of breaking in a new battery so it is a little hard to tell. The thing that concerns me is the sheer amount of 'loop' and 'flush' processes showing up in my kernel stats. I am attaching a log with this post. Is this normal? I just have never seen anyone with stats showing that many loop and flush processes listed. For reference that 1 hr 44mins usage in the attached log is with about 61 hours of up time on the phone with moderate usage (hi-capacity battery). I get the same sort of level of activity whether I have Wifi and data on or off, screen on or off, syncing off, bluetooth, gps, rotation off, etc. I may try a factory reset but was hoping someone might know a culprit causing this before I had to take that step. Many thanks!
Hello! I've been lurking around trying to solve my battery drain issue for two days without success. I have a d2att with severe battery drain, where battery would last for around 2 hrs MAX before shutting down at 40%. This was apparently an issue before (my brother was using it) when it was on stock unrooted 4.3. I installed Carbon 4.4.4 to look for improvements.
Symptoms:
Rapid battery decrease during use
Shutoff at 40% (when rebooting it would show 0%, when charging it will start at 40%)
Constant wake (I believe from the systemupdate wakelock that is unstoppable)
Feels warm during short times of use, cool when standby
Attempts to fix:
Using GSAM to monitor battery drain (just installed Betterbatterystats, will update with that info later)
Installed MyAndroid Tools and Disable service to stop systemupdate and checkin services
Autoruns to stop all systemupdateservice receivers
Dalvik cache wipe to try to fix the 40% shutoff
Privacy guard to turn off keep awake for Google play services and Android system
Privacy guard to turn off location for GNow
Have not done:
Replace battery (just ordered one that's coming in two days)
Clearing batt stats, as apparently that doesn't help
Factory reset, as it's a pain to setup again (Should this be next?)
Greenify
Xposed
I am just generally confused at this point at whether systemupdate service is turned on or off, or how to solve that, or if that is even the main problem, and what my next steps should be. I'm not an expert and can only understand half of what's going on, so any advice is greatly appreciated!
*Update: It seems that the phone is able to go to deep sleep (~50% of the time). When I use it just 5 minutes for texting, the battery can drop 5%. After reading from another thread, I re-enabled systemupdate services from Disable Services/My Android tools to see if that would solve the problem, and it looks like it is not hogging wakelock anymore; however it does revert on boot, similar to this: forum.cyanogenmod(.)org/topic/96459-systemupdateservice-wakelock-on-cm11-m7-massive-battery-drain/
Update 2: I flashed Liquidsmooth 3.1 stable instead. This time I used autoruns manager and wakelock blocker (included in liquidsmooth settings) to disable the services, but systemupdate service still manages to run, so I have to disable the block to somehow make it stop with every boot. Once that is fixed, deep sleep functions normally, but now the new problem is that Chrome browser app seems to be stuck in an AudioMix wakelock. I uninstalled Chrome updates and this seems to have fixed that issue, however battery drain is still severe (5%/2min) during active phone use. No application stands out in constant wakelock anymore, so I'm suspecting it may be the battery itself? I will switch to a new battery tomorrow to verify.
Update 3: Well since no one bothered to help, I will just post this for future reference as a log, since I solved the last part by the battery switch to an Anker battery. The phone still gets hot, and I still have to manually deactivate systemupdate service on every reboot, but now it runs for "normal" times 5-6hrs (heavy use).
To be honest, it sounds like you had a failing battery. It happens.

theres an xposed app called amplify that helps to block some wakelocks , startups and alarms. it might help.
