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

Need some help.
My phone stopped function. The battery died and now when i'm charging not charge.
I'm using KK Stock VDT-V20 on E975.
¿Does anyone got this problem?
Thanks to all!
Is the notification light blinking/shining red?
Finally I can charge man. But... I think the problem is with the bootloader. I reinstalled ROM and don't unlock the boot after that. Now I can charge the phone when is off.

Just noticed this. Mobile data still shows while on WiFi or turned off. I've rebooted a couple of times (even turned off mobile data, then restart, still shows) but it won't go away. No a huge deal... Just not right and bothers me.

Yeah mine is doing the same thing, wasn't doing that before the update.
I've always had it shown. And I don't know why.

That's strange, mine would only show Wi-Fi when it was on the 4g would only show while using data.
same here, if I believe the Verizon GS5 forums, same happened to them when Volte was pushed on their phones...

Are you running stock rom? Viper gives you the option to turn this on/off in their tweaks.

Yes, running full stock. This particular phone has made me nervous about rooting...

I could help you out rooting and whatnot if you want.. but with a stock rom you're pretty much stuck where u are. I dont see any toggle option to switch that.

Has anyone else's signal gotten worse with the new update? I use to have 4 bars at home, now only 1-2 although the speeds are still about the same.

Ever since the update my Spotify and Tunein keep telling me I am offline when I am not on Wifi, yet my browser works perfectly fine when using data...
Do you think having both is causing apps to have this issue?

I don't use either of those so I couldn't tell ya. I did notice that my 4g icon changed to 4g lte while I was on WiFi, makes me think it's still reading towers? Idk...

I have the same issue and a buddy of mine has the same issue also. I went to the TMO store to check their display phone which was already updated to 4.4.4 and that also has the same issue. So it's definitely a software bug since it was not doing this on 4.4.3. Basically when turning on wifi your mobile data should automatically turn off, it's not doing this on 4.4.4 and thus your battery drains faster since both are on, you have to manually turn off data. And when you do turn off data, the icon still remains even though it's not active. Only airplane mode would get rid of the data icon.
Seems like they're issues relating to calling and the camera also, though I haven't been able to test these myself. But overall I'd say 4.4.4 is a buggy release, battery drains a little quicker too.

I have the same problem, fully stock, never rooted. I did wipe the cache partition but that didn't make any difference. I would be curious to see if it persists after a full wipe but I don't really want to do that to mine at the moment.

Yeah don't waste your time with a factory reset, I did this 2 times before I called a buddy of mine and also checked the display phone at the store. Its a software bug and everything I tried has had no effect, problem still present. Hopefully HTC releases a patch soon to fix this because data is constantly on, it does not sleep. The battery definitely drains a little quicker.
Weird, I don't seem to have this issue. Running latest OTA, stock with root.

The icon is on... But its not active... U can tell its active when the arrows under it flashing. I also didn't notice its effect the battery.

I too have been having a lot of trouble with this update. Four or five of my programs that would work over 4G now only work when I'm connected to WiFi. I'm still able to watch Youtube and surf the web, but it's extremely aggravating not being able to play my games while I'm on the train to work. I wonder if it has to do with the radio update they pushed with the 4.4.4 release.
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...

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
Dont know. I never used it..dont have an account

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.
i have rooted by mobile now i got a problem i am not able to charge my mobile each and every time its has showing the same 50%
even after changing the multiple roms the problem is similar
so please help me
Then the problem is with battery....try a new one
