How long has your nexus 7 been up?
Mine is currently at 70 hours.

Well, mine went for about a day and twenty hours with about five hours and forty-five minutes screen on time. I haven't tried letting it drain without turning on the screen. I'm just too glued to it.

uptime != runtime
Anywho. I had to reboot mine because the wifi kept flipping on and off for no reason, since then it's been fine... 2.5 days..
Unless the kernel crashes, uptime can be rather high.. My Nexus 1's highest uptime was around 160 days.
Hi, there,
My note battery, or maybe system is a bit wired, normally when charging, CPU only use 200mhz, even in screen off mode, but today it was charging on screen off with CPU jumping 1400mhz, so it makes my note like no charge at all, but when screen on and do nothing the note CPU will drop till 200 MHz, any solution?

Do you have better battery stats and cpuspy installed? Have you tried a factory rs? Maybe something is running in background forcing such to occur?
Yup, I have them installed, I have this situation once, but it went well after a couple of battery taking out and cooling down, factory rs was my last touch, if using 3g, with 10mins of online game, the better battery show 13% used for an hour, is it normal?

13% per hour may be normal when 3G on & u r playing games..it may b even more if u r playing some heavy games..about the charging, AFAIK phone won't go to deepsleep during charging even if screen is off..so, processor will be running @ 200MHz..
Yeah I know, but this time it when to 200 on screen on, but 1400 when screen off.
Anyway, I already fact reset the kiddo, and everything seems to when back to normal, maybe is something I installed.
Thank you all for replying the questions.

Recently, twice in the same week, my Nexus 7 has been over heating to almost a burning heat. Now, every night I plug my nexus in and its usually around 30%. Then I put it under my pillow while I listen to a podcast and fall asleep. Then I wake up and usually it fine but today I got my temp gun and it read 138° F on the front glass. I looked at my battery status and it showed that it charged to about 80% and then the screen turned on and the battery was draining very fast while on the charger. I think that is when it overheated and the nexus couldn't vent air cause it was under a pillow. Would this screen turning on be a result of a bug in JB or could it be a rouge app? Or could it be that daydreamer thing that is like a screensaver.

What kernel do you use? Do you OC your CPU and GPU?
Oh, I'm sorry I didn't post those details. I am stock with android 4.2.1 with kernel 3.1.10-g22b4fcd. I am unlocked though

I looked at my battery usage history and my screen turned on around 3 in the morning and its draining the battery while its charging. So something is going rouge.

Download trinity kernel toolbox. This app will show you the cpu`s temp. The normal temp for the CPU on 1.3Ghz is about 60-75 °C...
dont keep your seven under a pillow while its charging,. thats the only way that you will get the battery temperature that hot. for a cpu temperature, 138F isnt hot. but for a battery temperature, 138F is very hot.

NEVER put these devices under a pillow while charging! You are asking for it to get fried. I did this with my phone once, and it was too hot to touch once I took it out in the morning.

OK, that solves the heat issue but how can I find what's drain the battery so fast.
Sent from my Nexus 7 using xda app-developers app
Had around 67% when I went to sleep. Forgot my charger at home as I was at my girlfriends, so I turned off the phone. I woke up this morning to see my battery at 23%! And while writing this post, I accidently turned it off again and now my battery is at 8%
Whats going on!?

Umh, you have the fastboot active?
And, the phone was hot?
Possibly android was reporting the wrong battery status when you turned it off. Charge your device to 100 percent then turn it off and on again without the charger plugged in. If it reads below 100 charge it again until it's full.

Yes, I had fast boot on. Searching around I turned it off. Didn't think that would cause such a drain...

Alright, I'll try that out when I get home. I was afraid my battery was defective or something.

Your battery could be defective but doing the steps I mentioned above will help rule it out.

Is possible that is this the cause
However, try with the other member mentioned
Thanks for the help guys. I guess it was fast boot... I tried it the other night and only lost 3%. At least it wasn't my battery
Sent from my HTC One using xda app-developers app
Because the fastboot is like the "sospension" of windows.
The OS is running in background with all the app open and all the service...
My phone has not always been this way. Its started in the past week. The battery seems to dive at the end of the day when I quit using it.

Anyone? Am I the only lucky person to get the bug?

Something... Looks like "phone" in your screen shot, is keeping your phone awake for a crazy amount of time. Solve that and you're good again. Google it.

it's the NSA!!!!!!!!!
I'm not sure the cause or a permanent solution. But if you see the battery dropping fast... Whether it's from "phone" or anything else.... A reboot should clear it up and you won't lose so much battery life.
That is, if you notice it dropping too fast. Sometimes you might not catch it till it's too late and you're running for a charger. Lol

It's pretty obvious some app is keeping your phone awake once you have solid mobile network signal. Time for you to find out what it is.
I have Gravity box installed. That's it. last night I charged it all the way up before I went to bed. I woke up with a 50℅ loss! This time it was the media server. Whatever that is......if I look on the wakelock detector there are 1000 little things but nothing stands out. Tonight I'll do the same thing but do a reboot before I lay it to rest.
What's weird is I only get this problem when the phone is not being used. If its of any relevance I leave the WiFi on all night. And have it set to turn off when the phone sleeps.

you should know the drill. start getting rid of apps to see if it improves. or, go reverse and start over, installing one app at a time. other posters above are right. you've got something else polling, that's causing the wake lock.

Seems like you could also just have some faulty hardware? e.g. a bad battery or charge sensor?

This is something fairly new. Unless it went belly up.....I still have more testing to do, which can take a while......since it only seems to be happening when I don't use my phone.

There is a bunch of apps to help you out
Usually i use this two
Wakelock detector
battery widget
Use those and paste a print here
Last night I left the WiFi on. Cleared all tabs in the recent and I lost only 28% .
Making progress. It was some app left running that kept it awake. Not sure what though.
Tonight I'll leave the WiFi off.
