Hi, I just got a nexus 7 (its been a month now) when the device is on standby it drains all the battery, in fact it only lasts 6h. In the battery usage, all there is is 'tablet idle' and 'WiFi'.
Till now I have tried clearing the cache partition, restoring factory defaults (more than once) and even signing in with a different user after factory defaults, nothing helps!
I managed to get proper battery usage maybe once or twice.
When this happens the top right part of the tablet gets really hot!
Any clues? Should I return it back to the US?

you need to provide information if you want help, have you installed betterbatterystats?
are you rooted?
No its not rooted. Betterbattreystats not installed as it needs root access.

man it could be anything....more than likely though you have a rogue app that likes to kill your battery. The best thing to do is go through your apps, and delete them one by one to see if you can pinpoint the app that is hogging the battery.
Just an update on this. I found out which app was draining my tab, believe it or not, it was the official google now launcher!

After some 2 months the issue is back!! I installed no new apps since the time I said it was sorted. I have also tried to boot in safe mode but even in safe mode the battery drains in a matter of hours

My Galaxy S III had a really big battery drop. Why is Gallery, Chrome, and Polaris Viewer taking up a combined 10-20% of the battery? How do I fix it?
Thanks!
P.S. I am completely stock and unrooted.

Do you leave them on (don't close them after use)?
Try closing them in running apps if you already exit them properly.

I always close all the apps I've finished using it (by holding down the home button), and it seems now that those three are always open.

Like I mentioned, go in settings -> manage application -> running applications and manually stop them.
If they restart on their own, then something is triggering them (most likely a app or setting).
I went into the Settings, and Android is showing that while they are using up battery, they are not running. And also, over the past hour, Android OS is using up 18% and Android system is using up 16%. Aren't they supposed to use up like 4% each?

Do you have bad signal?
Do you use Google Now?
Nope. I have full signal on AT&T and I haven't used Google Now in at least a few days.

Simply being connected to Google Now can be a big battery drain. Definatly something to look into.
Do you have auto sync on? the more things you sync, the more battery drain you get.
OK. And the only app I have enabled to sync is the email client, which only syncs once an hour.

I have a 2013 Nexus 7 and had no problems during the first week. One night i left it at 100% charge, and woke up to 70% i checked cpu spy and the device did not go into deep sleep. I literally tried EVERYTHING: factory reseted, rooted, installed custom roms and kernels and NOTHING fixed the deep sleep issue. Not even the JSS15Q update. I downloaded BetterBatteryStats and the process "pil-gss" and "powermanagementservice" are wakelocking the device. I did buy the nexus on Best Buy but i dont live on the us so its impossible for me to return it. I googled about "pil-gss" and didnt fint anything relevant. Please someone help me, the nexus is an amazing device but with the battery draining i think i will not be able to use it anymore :crying:
After a factory reset... Do you install apps or you have the issue without any app installed?

i even left the tablet on the welcome screen. Tried with no apps installed, even tried cyanogenmod with no gapps installed. Im frustrated at this point and i havent found any information about pil-gss
How are you charging it? There was a recent article on power management causing wakelocks with certain wireless chargers.

This seemed to start for me after the OTA updates were released, because my first week of owning it I had no problems. I even took it out of my new case with the magnetic lid just to be sure it wasn't caused by that to no avail.
Has anyone seen a way to remedy this? Obviously it's going to need a patch from Google, but is there a hack that might stop this?
PaulW from Google is apparently being made aware of the issues, I'm also having it, keep an eye on this thread:

I have noticed lately that the battery of my Galaxy Note 8 WiFi have become worse day by day. Today I started using it after charging to 100%, after 12 minutes and 27 second I am at 27% battery. Here something have to be very wrong. I am using original firmware 4.1.2.
Anyone have experienced the same using the Note 8.0?
I installed the Nexus 5 launcher and the supporting files, then I started noticing by battery usage went way up with Google Services hitting the top of the list. Had the same issue on the Note 3.
The sad thing is that the only was to clean this up was a reset, now my battery is back to normal on both devices.

Location reporting in google now kills the battery very fast.
disabling that in google's settings app fixes it, however if you are a google now user then that my not be an ideal solution.
I'm seen a lot of battery usage from Android System, even more than the screen usage (44%). I can't figure out what is is, does anyone have any suggestions?
same here, my phone drops 20% overnight/7 hours or so.
searched for a lot of solutions online, nothing works.
android os/google play services/ etc seems to be the reason.
im using gsam 60% over 12 h with 2.30 h SOT. LTE + wifi mixed usage.
im thinking of converting to GPE lollipop. If anyone has a solution please help.
Are you using custom ROM? Perhaps, the problem is in a custom ROM.
1st step, please post some screenshots of your battery life in your settings > power
2nd step, go to play store and download gsam and use your phone for a day or two after which post some screenshots of gsam.
3rd step, please indicate what ROM and kernel you're running (assuming you've)
4th step, I believe someone here will be more than willing to help you if you ask nicely

Have you tried a factory reset? Or maybe post screenshots from your battery app thats in settings?
Your wakelocks seems to be quite high as well as your wakelocks are what I would have gotten after 30hrs or so standby with 5~6hrs of SOT
I also did a full reset. Cache clear and battery calibration....im always on lte at work and on wifi at home...sometimes overnight i only drop 2%. Last night droped 20%.

Have you turned off location services and stuff? They could be the cause of your battery drain...
Everything is off. Rooted last night...uninstalled facebook zoe and polaris.
Only 2% drain overnight 6hours...seems ok...im gonna keep and eye on it...with wakelock detector.
Thx

Facebook and its apps are huge battery drainer. Guess that explains why your battery had such a big drop

I don't think root helped you
The factory reset when you unlocked your bootloader must have helped you! There's a root companion app for gsam, download it and enable root access, will help with the stats.
Flashed gpe 5.0.1.

Seems to me that you have something eating up your battery overnight... I'm not very sure whether its a rogue app or maybe mediascanner (if you have too much stuff on your internal storage)
I have VERY similar drain to what you had on the Sense ROM.
I am on GPE 5.0.1 atm. And it is what I put the phone on since I got it (got it used btw, but in good condition).
I unplugged around 9am, checked back at 12pm and it was 96% or so. Not very happy with that, shouldn't it be less?
I had 35% with 2.5Hrs SOT and that was around 8 hours later, NOT impressed at all!
Anyhow, I'm gonna wipe dalvik and regular cache and post a full (or close to) drain in gsam, will use it normally (like I would!)
I hope this thread isn't dead yet
P.S.: I had location on, it is now off (made no difference at ALL!).
I have BT On (but I've seen other ppl's drain, it's almost negligible because it's 4.0 LE and sync'd to Moto 360).
I have FB Messenger installed, WeChat, Hangouts and that's it for chat apps.
EDIT:
M8 wouldn't boot after updating SuperSU binary through the app and into recovery mode automatically (never again, I should ALWAYS just do it myself *sigh*).
Anyway, factory reset, wipe cache, wipe dalvik and loading GPE again through RUU.
Flashed Hypernova kernel as well.
Was struggling with battery life on my moto360 went into my battery stats on andriod wear app and saw motoconnect using 5% of battery. I know it's not much but I have deleted the motoconnect app but do not understand why it is still being shown with battery usage.

it access the watch for location, so that we can track till where the watch was connected with the phone (in case we miss it)
Makes since thanks for the response thought it was something within the motoconnect app that I earlier download from app store that didn't fully uninstall correctly.
