A couple of weeks ago my Nexus 10 started shutting down after being on sleep for a while. Really annoying having to boot it up every morning.
Is anyone else seeing this problem? Is there a fix? I don't think it's a setting that's causing this.

That is probably a sleep of death. Which if that is the case then it isnt exactly shutting down, just getting locked up and requiring a reboot to get it working again. The causes of his can be:
Too low CPU voltage
Too low GPU voltage
hotplugging is turned on for your CPU governor (some tablets dont like this feature)
severe bug in your ROM or kernel
Mine did this and I tried to troubleshoot it for 2 months before I gave up and RMAd it. New unit does not do this. View my profile posts if you want all the gory details.
I think you should RMA.
I have the tablet since December, this only started happening now

But have you installed a custom kernel? Or ROM? Did you change anything in the last week? Did an app update in the past week?
Stock here, No root or custom rom. I did the 4.2.2 upgrade recently.

i just noticed this morning after unplugging my note that even though my note is going into deep sleep the battery drain is still way too much as compared to the previous day...
i checked cpuspy and at first didn't register anything odd except that it goes into deep sleep.. after a second glance only then i realized that instead of running at 200mhz my note was running at 1000mhz during charge..
has anyone here experienced this before?? although i noticed that it seems to be a lot snappier now
i just can't help but worry what lasting damage it may be doing to the processor... and the fact that even though it goes into deep sleep i'm losing about 5% of juice for every 15-20 mins.
see screenshots below. the first was when i unplugged it from the charger and the second... after going to deep sleep
see screenshots
sorry forgot to attach screenshots

ANy new apps that u installed recently ?
Normally , rogue process is going to call an abnormal battery drain ,,,download some sort of process,app moniter and see which process is running and taking most of the CPU time......My guess is that it has to be one of the apps that you have installed or started which is causing this
That was what I thought initially but I don't remember installing anything these past few days as I just froze a few bloatware and was monitoring the device for any issues.
The last thing I remember changing was some setting under the development concerning background process.
Hmmmn. Maybe I'll put it back and see.
Really appreciate the help guys. I'll keep you updated.

this may be the reason - afair this setting kills each process after you leave it, so in readily you might have ended with a constant loop of processes being closed and then restarted by system

i unchecked the limiting of background process but still the same... cpu is still running at 1000mhz most of the time
i did a hard reset by turning off and pulling the battery for a few minutes... still the same although the note still goes into deep sleep but hardly uses other cpu speeds except for 1000mhz...
i tried freezing some of my apps and games, those which i suspect might have required 1000mhz to run but still the same...
i guess i'll just have to wait and see for a little while if this changes...
i'm now thinking of reverting back to GB... since the battery drain for ICS is such a let down and with this problem... i'll give it a couple more days
what ROM are you running?
anyway something in the governor seems to have changed ,your case seems to be a performance governor.
try installing set cpu and set minimum to 200 ,max to 1400 ,and the governor to "on demand"
should fix things for you
IM on stock Ics lp9. I haven't root yet after I upgraded ota.
Set CPU requires root ain't it?

yes it does ,but if you're not rooted then the governor couldn't possibly have changed by you !!
could it be a bug in lp9? I heard that ICS have some battery issues
how long were you running LP9 before noticing this issue?
Well, havent heard it from that rom. Bring it back

I was using lp9 for about 2 Weeks after I started noticing the CPU usage
Couldn't find a fix so I reverted back to rooted lc2 GB
With all the issues with Ics - battery drain, fc's and mmc bug and now this CPU overclocking felt it wasn't worth it.
Now the note is sleeping like a baby. Battery is back to its efficient self. I'm getting 3 days on one full charge.
Will just wait for an update on official Ics.
Appreciate all the help guys.

I used his app from the play store since it was in script form on the T989 forums. Having experienced the battery saving it provided on that device is curious if anyone had already installed it on the nexus? I emailed him concerning compatibility but have yet to receive any word. Any ideas?

I've been using it, prior to installing it my phone would never deep sleep and after im getting deep sleep fairly quickly after the screen shuts off.

#WhereismyNexus4
Just wondering if anyone knows what these spikes might signify?
I had a Nexus for 2 weeks and the last few days it was turning itself off like the issue here every night:
http://forum.xda-developers.com/showthread.php?t=1830546
My post is there too. Previously, I only saw one spike with the old Nexus, now I see more.
I exchanged my Nexus 7 for a new one yesterday but does the battery still have issues? It doesn't turn off at night so far but my Battery Info graph shows even more spikes now.
Any engineer know if this is normal or safe?
Thanks!
Still happens
I exchanged the Nexus for a new one.
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.
Some ppl reported that after official 4.2 update their battery drains while screen off. Issue was resolved with factory reset. I have same issue. Didn't had the time to do factory reset yet.
Sent from my Nexus 7 using XDA Premium HD app
For me, I'm not running 4.2 or have i upgraded on this Nexus. On the first one i had, I did update, and it seemed to slow down the tablet.
This one was stock and then I rooted, put CM10 on it and then Franco Kernel.
This problem worries me because it makes me think something is traumatizing my tab enough to shut it down at night and I can't figure out what it is.
I don't know if I want to keep it if it is going to keep doing this. But I do love this tablet.
I wonder if this could be a cyanogen mod problem? I've read about some people having a power problem with cyanogen,nobody has said anything about their tablet getting bricked yet though. That's what I'm afraid of.
So I've had this problem for some time maybe a couple of weeks.
The problem is that I sometimes cannot wake up my device after setting it down for sometime. For example if I go to sleep get up the next morning and then screen will not turn on. I have to hold power button down for multiple seconds and press it multiple times. Also one recent occurrence of this there was massive battery use. See attached photo.
If anyone knows why this is occurring or knows any remedies that would be appreciated.
Using PA 2.54
Franco Kernel
I can provide more information if needed. Just ask.
Thanks

I was having serious issues with my 16gb. Very hard to turn on, sometimes hold power for 10 seconds, sometimes 30, sometimes 5.. all over the place. And it only started after I believe the 4.2 update.
Also, it was draining battery while off. Charge it overnight, leave it off the entire time, come back 8 hours later. Turn it on and only have 50% battery.
Sometimes the charging animation would lock up while off as well. And if the device was turned off, and you plug it in to charge, it turns on. It shouldn't.
I think I've narrowed it down to the bootloader. My bootloader was at 4.13, and Flashing the 4.2.1 and 4.1.2 factory images didn't help.
Last night I finally fixed it. I ran the 4.1.1 factory image. Which put the 3.34 bootloader back in place. This wipes the device. So I flashed the recovery back and then reflashed Paranoid Android 2.99B6. All is good now, it turns on like it should, doesnt come on when plugged in, etc.
Meanwhile a new 32gb I have I can flash the 4.2.1 factory image, and I have no issues with that one.
Which bootloader are you on?
Hmm. That seems to be the exact same issue I have!
I just checked my bootloader and I have 3.41. But I never went up to 4.2. I stayed at 4.1.2 with PA 2.54.
Hmm. Maybe I'll try what you tried!

You can flash the 4.1.3 bootloader from JB 4.2 and use it with 4.1.2. I am, and it works perfectly and I never have a problem booting or bringing it out of sleep mode.
I think it was just your Franco kernel. Kernels are typically the cause.
I'm running PAb6 and no problems.

Hi, which kernel are you using? I just changed my bootloader back to 3.34 and my kernel to motley. See if that helps.
Thanks for the tips.

Sometimes you have to set you're minimum cpu frequency above 200 using one of the various cpu or kernel tuners

Just had this similar problem. I drained the battery to about 11% on wednesday night, so i shut it off and charged it to 100% on that very same night. Turned it on on friday night (It should have been turned OFF all this while) and it wont start. After the help of the AC charger, it came back on and found out the batt was at 0%. Which should not be the case even if the tablet was accidentally switched on because theres no way it can drain from 100% to 0% in just 2 days. And everytime i leave it plugged into AC it suddenly turns on and shuts down due to low power. Am using TWN ROM V1 (Android 4.2.1) with M-Kernel A17 kernel if that has anything to do with it.
So I think I have it figured out that if I set my wife policy to keep awake always no problems, but if it is set to keep awake only during charging, I will have problems
I will try it out on a higher cpu setting with semi awake

Just wiped the device and flashed CleanROM 3.0 on it and NOTHING else (No extra scripts, custom kernels, radios..etc) and it seems to have been stabilized. Although the battery drained pretty quick while i was using it last night, but I was installing apps and setting up stuff on the nexus so its not a very accurate benchmark. Will continue to monitor.
Hmm, I see. Well that's great that you solved it
It seems after switching my minimum cpu to 200. It still froze when I was trying to wake it up this morning
Maybe a full wipe is needed...
Sent from my Nexus 7 using xda app-developers app
Yes you should have done a full wipe like I did. All still seems to be good on my side. Looks like for my case it was M-Kernel a17 causing the problem. I doubt such a thing would happen due to a faulty bootloader.
So I did a full wipe of my tablet and instead installed PA 2.99 b6, flashed correct gapps, then flashed the beats audio v3b2 and the same thing occurs.
im using franco kernel v30 no OC just gpu oc to 446.
my tab if i leave it unplugged and set wifi policy to keep wifi on during sleep only when plugged in I get this problem that I cannot fix... which is the tablet freezes or something and i cannot turn the screen back on until i hold the power button, Then turn it back on. Also on a side note for the first time this morning, the back of my tab was hot, which never occurred when i was on PA 2.54
Any insights on this issue anyone?
full wipe and flash a ROM that comes with the stock kernel. I did that with CleanROM 3.0 and its still working fine to this day. Will probably try flashing franco or M-kernel again when I have the time. But for now it seems that a custom kernel might be the issue here.

Thanks for all your replies. It seems to have fixed it after updating my ROM im really not sure what happened with PA 2.54 but with PA 2.99b6/8 it has not freezed at all, but then again the min cpu freq i have is at 340 heh...
Anyone got an issue where after some time (can be one week plus), you pick up your tab and the touchscreen is completely unresponsive on the lockscreen, can't even press powermenu? Reboot fixes. I had it on JSS1J and persists into JSS1Q. Hard to isolate as it may not happen for say a week of uptime, seems to be no pattern or consistent trigger

I been getting the same thing. Charging over night the tablet wakes but touch is unresponsive. I'm on Clean rom and Elementalx kernel. Yesterday morning after 8 hours on battery and unused it woke and touch was fine. This morning after 6 hours on charger, over night, it woke and touch is fine. Need more testing.
Note: yesterday afternoon I update Elementalx kernal to 1.3
Yeah elemental or stock it happens

I see this from time to time on mine. What sucks the most is when the damn alarm is going off and I can't do anything but hold the power down to reboot. Wife loves this "feature" in the early AM.
I have an unlocked bootloader but I'm running stock kernel (3.4.0-g6537a16) and stock JSS15Q. I do see random reboots as well, seems to be related to the screen going to sleep by itself but I can't reliably reproduce it.
Happens to me as well. Annoying.
I had this on stock locked so its nothing to do with bootloader or custom kernel/ROM.
Curious if a CM based ROM will affect this i.e. not stock JSS1Q based.
Is everybody facing this touchscreen issue? I am planning to get the new nexus 7 2nd Gen from canada. Is it something you can discover in the first week itself because the person who is bringing it will get the tab a week before her return.
If you're lucky it'll show up in that time period.
Others have gone 10 days.
Have them put off buying until the last second....
Same thing happening to me. The screen becomes unresponsive. Happens in the morning when the alarm is going off and have to reboot. I just updated to ElementalX 1.4 and hoping it'll fix it. I'm hoping Google comes out with an update soon because my screen sensitivity sucks sometimes. It's not registering my taps.
It doesn't lol it's either hardware or something in 4.3base

My one, after 10 days, dead, the touch screen has no response at all
sent back to repair for over 1 week, still no news on when can return..
really bad feeling with this Nexus 7 (2013),
only Nexus 4/7/10 has no problem and still working well till now.
I faced this as well. But it solves itself.

I experienced the same issue here. However, I am not able to reboot as I am still running on stock and don't have the debug option enabled. Pushing the power bottun for some time only brings up a menu where i may chosse to shut down. As the touchscreen is not working, I cannot do anything. Unfortunately, my battery is almost completely charged. Any ideas how to reboot?
Coincidence: The touchscren went unresponsive after the alarm clock went off. Maybe there is a connection?
Here's hoping JSS15R fixes this (fat chance hah)

Hold down the power button until it reboots.
I had this issue exactly once since I got mine, and it's been fine since. I suspect it's a hardware or driver issue.
