check the Wifi advanced setting.
Turn off the always scanning. This always do the tricks.
Everytime you flash 4.3 rom, this checkbox will always default to "checked", try to manually unchecked it.

Try do several restart your phone and observe if problem still occur. I experienced this problem too and you also notice after the update RAM usage is higher. Mine normalize after several restart. Hope this solve your problem but don't worry there are plenty ideas to be share to you..
Wifi scanning was already unchecked......hope the restarting trick works....thanks......

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

with the new KK update , most of them are including me seeing the usual battery drain via google play services or the Android OS system,
not too sure if we have a fix for now , but can you guys share your battery stats after the KK updates ?
I have got no problem in battery drain in KK as well. I don't know what is happening with your device.

Yes ..The battery is draining fast...!
I also noticed the battery drain after the KitKat update of my device... Previously my device used to last for 1 1/2 day after full charge with a moderate usage. But now with the same usage, Its draining fast and lasting up to evening only...! Is there any way to revert back to Jelly Bean...? My primary concern for buying this phone is 6" display and battery stamina... The kitkat update is eating up my battery...! :crying:
Yes.. The battery drains out quickly
few days after upgrading to kitkat... the battery is draining out quickly.. now i have to charge the battery twice a day... tried to force stop many applications... but no use... please anyone help me....

Well maybe i installed to many app then...thanks for sharing mate
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.
Ever since I rooted this thing, whenever the battery completely drains and I plug it in, the screen stays on the battery symbol and doesn't charge until I get it to power on. Any ideas why this is happening? It is annoying when I forget and expect it to be charged.

7, 8, or 10 inch? WiFi only or with a data plan? Stock based or aosp based Rom? Which Android version? Which recovery?
