Strange battery usage behaviour

I have a strange issue with my 32G WiFi FLO that I was hoping the knowledgeable members of XDA could help me diagnose.
Since I got it at launch, it's been sucking the battery dry. But not consistently. I have no idea what or why, but here's what I know so far:
All details are with auto sync OFF. WiFi OFF on sleep, location services ON (but cannot use WiFi)
Not unlocked or rooted (stock)
- From boot, and for the first 20-40 hours after that, battery usage on standby averages out to around 0.13% per hour.
- After that, and for no reason I can discern, battery usage jumps to an average of 0.84% per hour, and keeps draining like this usually until I reboot or need to charge
- Stock battery app shows no apps draining, BBS shows no apps draining stuff or excessive wakelocks and indicates the tablet is spending most of its time in deep sleep.
- Life with screen usage seems to be around 7+ hours either way, so this is as expected.
- Sent to ASUS to diagnose & repair, received with note that front camera unit replaced and OS reloaded.
- Issue is still occurring after "repair"
- apps running at the time are usually Android Keyboard, Android Services, Settings. Sometimes Play Store, Currents (even though I don't use it and have never launched it), Google Play Services as well. These are the only apps that run regardless of state of battery drain.
Can anyone think of any reason this is occurring, or where else I can go to check for more info? I'd prefer to stay stock/unrooted.
I'm looking to send it back for RMA *again*, but I'd rather tell them where to look than try and trust that they'll know where to look to fix it this time.

Guess no-one else has this issue or any ideas on where to look for this, since there are no replies

[Q] Htc desire 601 battery drain

I need help!!!
I am running on android kit kat 4.4.2 (not rooted) Since last update Google play services keeps my phone awake even when phone is in sleep AND in safe mode. Like I said, I was using my phone in safe mode for twelve hours just to be sure that none of installed applications is not draining my battery. When I went to sleep last night battery was at 76% and after 6 hours battery was at 11%, when I checked battery history, wi-fi was off while phone is at sleep, "network signal" line was solid (as it suppose to be) and "keep awake" was solid blue also and it was running for 7 hours 16 minutes, straight (which is NOT suppose to be). And imagine my surprise when I saw GOOGLE PLAY SERVICES among running apps exact period of time!
It is obvious that Google play services drains battery. What can I do to prevent mentioned app to suck out life out of my battery and still to be able to use application that needs Google play services.
Thank you in advance.
I forgot to mention that I am dealing with this problem 15-20 days already and that I tried almost everything. Location is on gps only, wipe cash in recovery, remove battery, battery calibration, right now running in safe mode.........etc, etc, etc

Hi
have you disabled google play services ?
or you can try the following Google settings >location >location mode >choose battery saving mode or device only
battery saving and device only should reduce battery drain if you have to have gps on, otherwise shut gps ,Google play services can still function without gps .i think high accuracy while more accurate it is not yet optimized for day to day use yet
The Google play services affects most devices which have kitakt

Several of my coworkers have this phone on Rogers. They have had this problem for years. The phone stays "Awake" all the time, even when the screen is off.
I have the same one but on Bell. It worked fine for about 2 years. All of a sudden this week I have the same problem as them. Phone stays awake all the time and battery now goes dead in ~4-6 hours instead of 2-3 days when not used.
Very frustrating. Any known fix is appreciated.

[Q] Battery drains very fast

Hi,
During the past week I have a very strange problem in my Galaxy Nexus.
Battery suddenly started to drain very very quickly.
After 8 hours while I am sleeping in which 3G \ Wireless \ location services\ sync etc. are closed I lose 25-30% battery. (Before this happened I would have lost only 10% in this situation).
Of course while using the device the battery drains even faster.
Luckily I have 2 batteries and use both actively, second battery started act like the first, so the battery is not the problem.
In the battery usage screen there is nothing suspicious.
I installed Wakelock Detector and Better Battery Stats, everything is fine there too.
I have Greenify and I hibernate all the unnecessary applications.
I had a PA rom when it happened, then I switched to SlimKat, same problem. Then again I returned to the PA and the problem isn't vanished.
Between changing ROMs I've erased the phone.
I've also tried to put custom kernels but nothing helped me!
I have no more ideas, can someone please help?
Thank you very much!

I noticed this too, under battery info in settings I found the only culprit to be the latest/updated Google Play Services that kept preventing my GN to enter into deep sleep mode and the only way to fix it was to force close this service.
But then every once in a while it would start running again, so now I've just put a shortcut icon on the home screen to help quickly force close it from app info.

Huge battery drain

First let me give you my phones state
Full stock
Was on Feb update, yesterday (after 2 days of the issue) manually flashed through android recovery to march update and bug fixes.
Not rooted.
The past 3 days my nexus 5x battery has been draining very rapidly (97% down to 32% last night), nothing has changed in the system that i've done and no apps updated aside from google docs and amazon I think. I had installed a few new apps (All4 and iPlayer)) but have since removed these to remove them from a list of culprits. Prior to this battery life was brilliant.
Currently in the process of resetting to factory to see if the issue is more deeprooted. If this fails however im not sure what else it could be besides my battery dying.

Check what drains your battery. I had simillar problem.
When I opened the battery screen i saw quite large drain from some service 10112
I was able to open the service and notice it had something to do with GPS and it basically turned the GPS on without my permision (i had gps turned off)
Then i noticed it even set the GPS to high accuracy and that caused the drain. I switched the gps setting to battery saving and the problem was fixed.
However, I still havent fixed it fully because last night it turned itself on again, and my battery dropped from 79% to 65% within hour.
I did the same thing and it stopped the drain again.

Ok thanks will see if it happens tonight after full reset, I did check battery screen but the highest on there was Google play services and even that wasn't that high (4% and some small mah figure).
I permanently leave my location on battery save and previously have had no issues.

Did you restore from a previous backup? Do you have Snapchat?

No backup as not rooted etc. No snapchat.
Just reset device and reinstalled. All seems fine over the weekend no unusual battery drain.

Suddenly Bluetooth Wakelock?

Hey Guys,
for about a week now I am experiencing a huge battery drain which seems to be caused by Bluetooth (bluedroid_timer).
I got my OP3 since release and never turned off Bluetooth, was activated all day long without any issue and no battery drain. Then suddenly last week I noticed that my battery life went down way faster than before (it was almost 2 days before, then suddenly only about 20hrs if at all).
I checked recently installed apps but none caused that drain. Checking gsam + wakelock detector both say bluedroid_timer keeps the phone awake and is draining battery. As soon as I turn off bluetooth the battery life returns to normal, so for now I just keep it off which is of course not a real solution as I need bluetooth while driving or at home for music...
Was reading through a lot of threads and it seems to be a well known issue, but couldnt find a solution yet.
What I tried so far:
- uninstall all recent apps
- delete system + dalvic cache in recovery
- delete bluetooth data / removed all existing bluetooth connections
- some other stuff that didnt work...
Anyone knows a fix for this? I would love to prevent doing a fresh flash (or factory reset) and starting from scratch...
Thanks a lot!!
