This has been going on for about a week or so.
At first I kept finding it off in the morning after charging, and then it became more common. Mostly happens when the screen is off but not always, I've had it turn off twice whilst I'm using it for example. A couple of times it has needed a long press to restart it before it will turn back on. Right now it has turned itself off and will not turn back on.
Battery has never fallen below about 50% throughout so it cant be that. It doesn't get heavy use so I'm not convinced its overheating. I had a look through the app list and none of them seem to be obvious candidates for the problem, and if i cant get the thing to turn back on I cant even test that.
I think this one is going back to HMV asap but I was wondering if anyone has any ideas for me to avoid the problem with its replacement, or if anyone is having the same problem. Its a shame as I've been really enjoying my Nexus.

Hi, I had the exact same problem and ordered a replacement from the play store. I never found a way to fix it, I would recommend you just get a new one from HMV. I hope this helps
This actually just started happening to me yesterday on my 3 day old 16GB Nexus 7. I kept mine plugged into the AC all weekend, and yesterday watched it shut down itself once. Thought it was a fluke and just turned it back on...left it running overnight...pick it up this morning and it's turned itself off yet again. I guess I'll have to return this one before it completely doesn't turn on anymore!
Bah. Thought that might be the case.
2 days off charge (and some time on charge) and mine still wont turn on.
Definitely going back for replacement.
Elsydeon, it sounds like you should do the same. Took about 4 or 5 days to go from irregular to brick.
I seem to be getting the same thing... Once every day or two I pick up my Nexus and the screen won't turn on, I hold the power button and it starts booting up. I haven't had this while charging (maybe because the screen is on while charging??)
For those of you who traded in for a replacement, did this solve the issue for you?
I was getting this, but was using one of those magnetic cover/cases. If I wrap the cover round the back of the N7 whilst using it, the magnet in the case/cover is sometimes strong enough to turn the device off from the back!
Mine has powered off twice now

Just wondering as well like the last guy if swapping for a new one helped this issue.
I actually have looked at the battery data and think somewhere the nexus has gotten a power spike that turns it off but not sure if that definitely is the issue.
If it is, perhaps it's where we are plugging in or a failure with the AC plug?
Ideas? I've attached a photo. I hope it uploaded.
Thanks.

Me too
unless i hear different from anyone here, going to exchange it for a new one today ... only been 2 weeks from Staples.
Actually going through the data, it's happend the last 3 days now.
I wake up to the white battery symbol.
By the way, for future ref, is bootloading warranty killing? I am in the process or restoring now just in case.
Thinking of getting their replacement plan now too because of this episode.
Thank goodness for titanium backup
Nexus 7 32GB Display Keep Turning Off
My Nexus 7 32GB tablet's display continues to turn off at random times also. It happens while I'm watching a video in landscape. But then I stop the video, go to the home screen, and it still turns off. I already replaced one last week and now its happening to my new one. Anyone got answers? I'm going to call google device support today. Maybe if enough people call, they'll do something about it. Their # is 888-836-3987.
Still happens

My NEW 32 tab worked out fine for a night and woke up today to the full battery indicator and tablet off again.
I have a new insight though, somehow the battery temp is rocketing to 100 and I'm guessing that is when it shuts off.
It may be because I am using SetCPU to limit my CPU speed to 300mhz when the screen is off. Maybe the tablet is trying to update all my apps while I am sleeping? It shouldn't use so much power though.
I'm going to try to create a new command to let it use it's whole CPU as long as it's on AC and screen off and see what happens tonight.
Happened overnight again. No insights? Does anyone think my nexus will finally brick sometime?
I don't know anyway of testing what is up with this thing? Thanks.
Nexus 7 Screen Keeps shutting off - Fixed
To those experiencing issues with their Nexus 7 screen randomly shutting off.
I just received one for Christmas, and thought this dang thing sucks. The screen would stay off and only show for half a second when I click the lock button to turn it back on.
The issue what the case. The the case, when folding back, contains a small piece of metal on the click. This little connection, thought not direct, causes the screen to shut off. I've tested it out multiple times just to make sure.
Again the FIX is, keep metal away from the back of the nexus, it doesn't like anything that can cause a magnetic field. Even if the metal is enclosed by something.
nexus 7 screen turns off
For those of you who are experiencing intermittent screen display going to sleep mode or turning off you can fix it by removing your tablet cover. Some third party tablets come with different strength magnets stitched inside the cover. The magnet is used to activate the nexus tablet smart cover functionality. If you flip the cover to the back of the tablet the magnetic field may cause the tablet to think it should turn off while in use. Get rid of your cover reboot your tablet and notice that the screen will stop turning off. Hope this helps.
Hi, I also had similar problems with my Nexus 7. After removing the back of the unit, I saw that the battery was nearly unplugged. I simply popped the connector in and voila! no more SOD, turning off, nothing.
So, the Nexus was probably turning itself off because there was randomly no more power comming from the battery.
Here's a link on how to remove the back shell : http://www.ifixit.com/Teardown/Nexus+7+Teardown/9623/1
Look at Step 4.
That Fixed It!

I was researching before going to get my Nexus 7 replaced today as it also started having this issue. After reading your post, I took your advice and removed the back to find that my battery connection was also barely intact! Thus it would lose power any time it was bumped slightly to that side. Now that the connection is securely in place, I've had no more problems!! Thanks to you StefGou!!!
Hey guys. A few hours ago I encountered the same said problem. I woke up to find the battery was depleted so I charged it. It turned on by itself and stated that I have 6% battery left. As I wait, suddenly the screen was like distorted and give me static sound then shut off. Numerous trials later end up the same. So I just put on the charger thinking to let the battery full. To my surprise, there was no indicator that my N7 is charging. I just leave it charging and left. About an hour I got back it still nit charging. I boot the N7 and it still on 6% battery. So I followed you guys handsomely instructions to remove the 3rd party cover and now my N7 is back. Thanks guys. But I wonder why it is happening now? I've been using the cover since forever.
hi all, today when my nexus 7 left around 15% battery, it showed the warning sign to ask me charge it, so i thought of finish download 1 small apps before charging it. just before i hit the install button, the screen suddenly turn off and whole device was power off.
i tried to on it back (press for 30sec) but no use. so i go and charge it, after trying many times, i finally managed to on it back, but just after few minutes, the screen appear many lines ( just like those old tvs) and it turn off again...then, i tried many times only i managed to on it back.
after that, i continue to leave it there to charge. but after almost 4 hrs( and still counting), the battery only 45%.
wat had happen to my nexus 7? previously i had no such issues, and normally i can fully charge it within 3 hrs. i just got it for 1 week, can anyone tell me what happened? will it damaged my device?
thanks.
no people facing same issue as me?
hey there, im facing the exact same issue and symptoms as you!
the sudden off, the old screen tv effect and shuts down again.
a battery logo appeared though and im leaving it to charge now. strangely it was showing 18%
im running cm10, what about you?
I've had the same issue for first 2 times I charged the Nexus, then it went away. Seems to be battery related, faulty battery?
Same thing happens to me as well. Happened on stock 4.1.2 and happens on stock 4.2 as well. I never try to let it reach below 20%, just to be on the safe side.
Me too!

It happens to me too
Not sure if it's battery related but it happened twice and this is what my battery graph looks like.
Anybody with more info?
I am also on CM10 using setCPU app to control CPU speed when the power is low.
There is one other thread talking about this:
http://forum.xda-developers.com/showthread.php?p=34878700#post34878700
I placed my info there too.
Edit: It's actually happened the last 3 days now ... I'm going to exchange it today.
I get a message "shutting down, low battery" I used to get message telling me to connect to charger. Before I could finish what I was doing now I have no choice. Seems to happen after update 4.3
fix
somehow the battery calibration is out. only fox is to leave it charging for about 20 mins before trying to turn it on. as by then only will the 'x' logo appear. OR if you cant wait popout the back cover, remove/unplug the battery it works. another longer fix is to. turn in back on after it is able to, go to battery settings refresh it, plgg and unplug your charger. the shutdown logo should appear again and when you look to the top, the battery % will revert to its correct amount of 0% try to do this as soon as it is able to be turned on.
I was at work today, and i pulled my phone out and it was off. I tried to turn it back on, but it wouldnt. I hooked it to the charger and the light never came on. I had to pull the battery to get it started again. It booted fine, and all seems well. The only thing i see weird is that all the preloaded bookmarks i had deleted long ago, somehow all came back. I was just wondering if anyone else has ever had this happen to them, or what would cause it. My first thought was the battery died, but it was fine.
I would imagine i just went thru that right now. I dont kno what xauses it but it caused me to panic lol you dont have to do a battery pull it wastes time and can break yur back cover(i did ) anyways i think its a phone thing maybe deep sleep? Idk but hasnt happend before
Sent from my rooted GameBoy Color!!! ^¬^
every now and then when i pull my Verizon S4 out of my front pocket (screen off), it seems locked up when i try to wake it. sometimes the bottom buttons are lit up (menu, back) but the phone is unresponsive. i hit the power button a few times, or hold it for a while, press home, or whatever, and it generally reboots eventually. any idea what could be going on?
could this be a samsung sensor that it is in my pocket? i don't think it has ever happened outside of my pocket, but is has happened 3-4 times now.
it never feels warm, so i don't think it is overheating. i have a TPU case, so i don't think the power button is getting hit (although maybe it is).
i'm on Beans 6 with the KT kernel, but i think (i'm not positive) that it happened even when on stock.
Iv had very similar problems, and have been doing some reading, and it looks like it could be battery related... some one on another forum (could be this one cant remember) said that they had the same issue with there stock battery... I have just replaced my battery yesterday, ill post back later 2day\2moro.
For me when it was in this locked up mode and i connected the charger, the state of the phone was like it was fully off, the green battery charging icon would be shown on the screen, and then i could use the power button to turn the phone back on.

interesting. let me know what you find.
since this is happening when m phone is asleep (unlike many complaints about it happening when using specific apps) I am curious if it may be related to my KT kernel tweaks, which i copied from an expert, and which set certain CPU parameters to save battery when the phone is asleep. i'm going to try reverting those to default, or maybe try a different kernel.
Hey Mate, so far the phone has been real solid, iv had no lockup or anything with this new battery... still could be coincidence.. but its working great!
Hey everyone!
I recently left Samsung and decided to try out Nexus 4. I actually planned to test it out so I kept the plastics on the charger and everything, and left everything in the box because I want to sell it for the Nexus 5. Anyways, I've used it for exactly a week now and it's been working just fine, but last night was the second time I left it charging overnight. Since I kept all of its stuff in the box, I use the charger from my Nexus 7 to charge it. It's been working fine so far, but today I woke up from my alarm, took my phone off charge and it worked perfectly. I went back to sleep with the phone beside me and when I woke up, it wouldn't turn on. Anyways, I got really worried and eventually it safe booted when I pressed power + vol. down. I pressed "Start" and now it's up and running but when it powered back on, it showed 85% battery instead of 100% considering it was on charge for about 8 hours. I know this isn't because of battery hibernation because I put it on charge while it was at about 4% I believe. I've looked around everywhere online and I can find people with similar problems but all of them have something like the phone going into hibernation or such. But Mine did not do anything like that. Can anyone please explain why this happened? The phone still has warranty but I really can't afford to go without a phone for 3 weeks if I send it in. Thanks so much!!!
P.S. It's running the latest KitKat, I've never rooted it, flashed it or anything like that. I am running the Google Experience Launcher.
Edit: I read that Nexus 7 chargers use 0.8 more current that the Nexus 4 chargers. Can that be the case? Thanks again guys!

Charger could be one problem. It's better to use the stock one.
What you had there was a BSOD ( black screen of death). Basically, the cpu gets stuck when trying to sleep. Software issue. Battery consumption is higher. Plus a reboot may have taken some more battery.

Phew! Thanks!! I was so worried that this was a hardware issue! I am a developer so I was testing out a tetris app yesterday, that can be probably cause I guess. Or maybe that just happens to the CPU sometimes. I've never done anything to overload it or anything but maybe it was working too hard to control all that extra power it was getting from that Nexus 7 charger. But that makes alot more sense! I was really worried because I baby all of my electronics and I would hate to have to send my phone into Google or for anything to be wrong with it. Software issues can all be fixed with a factory reset right? Thank you so much! I was extremely paranoid! Thanks!
