HELP,
yesterday, I was using my nexus 7 for normal use, wasn't playing game, just browsing with chrome. the battery was 8 percent when I last saw it. I then proceed to charge it, but the thing suddenly just shut down itself. I thought I misread the battery percentage, so I charge it anyway. about an hour later, i checked on my nexus 7, turn it on, got to the boot screen, got to the home screen, use it for about 15 minutes, and suddenly, the screen black out, it was flickering like crazy, and making some white noise ish sound. I panicked so I hold down the power button and turn it off. I turn it on again, and after about 30 seconds, the same thing happened again. I was using motley's kernel with 520 GPU, and I thought, maybe my nexus 7 cant handle the GPU OC. So I went to recovery, tried playing with recovery for about a minute or so, but the screen didn't flicker at all on the recovery. So I flashed the 484 GPU version of motley's kernel. When I reboot to system, the same thing happened again. So I thought, maybe if I restore to my old backup, it would not be like this any more. so I wipe the data, dalvik, and cache, and I restore my old backup. But the same thing happened again, only this time, after I turn it off, it make a high pitched sound.
I waited for about 6 hours, and now when I turn my nexus 7 on again, it works normally.
So, what has happened to my nexus 7?

I'd say it is the overclock. Graphic cards do some weird stuff when overclocked. You can burn up your GPU doing that and cause it to forever freak out. I always shied away from GPU overclocks.

would that cause any permanent damage?

It should be ok if you reflash back to stock rom to make all the hardware back to reset mode. A warning always given when we try to flash rom with oc created.
i also experienced this one, also received a battery warning and then suddenly screen went blank. then same weird thing happened as the one above. I'm on paranoid android rom and i'm quite sure it's not overclocked or something. Was only able to get back to normal by holding the power button for around 15-20 seconds...
Happens to me
This will happen to me a lot when my nexus 7s battery dies, I plug the tablet in and then immediately try to start it up. It will work for around 30 seconds then look like an old TV without a signal. I am on stock everything, no rooting or custom Roms (yet). I always thought it had something to do with battery calibration being off and the tablet not having enough power to run, because it always works fine when I charge it before attempting to boot.
I have also noticed that every once in a while the screen will have a vertical line of pixels flicker.
Same thing happened to me yesterday...
I got the "low battery" warning and after some time the screen started flickering in many colors and there was a weird static noise.
I pushed the on/off button, but it wouldn't turn on again. After a few minutes of charging, I could turn it on again.
This isn't normal behaviour, is it? Shouldn't the N7 perform a regular shut-down when the battery has no juice left?
I'm on the rooted stock rom btw.

I faced the same problem. I dont know when the battery might have drained out, but on starting the tab on low battery, it suddenly started showing black screen with little grains and suddenly stopped with a noise. I charged, started the tab again while charging, and the battery reading stuck at 21% even after charging for 20 mins. Within 5 mins, it happened again. Now after 35 mins of charging, I start it again, it boots normal, and now its reading the battery percentage in an incremental value (started with 22%) and now its again stuck at 23%
Is this a HW related issue? Or do you think it is more of SW related issue? If it is more towards the HW side, we better have it replaced. Mine is C70 model.

just happened to me... it may have run out of juice... didn't turn on when I tried, so I guess it did... then I put it on the charger, tried booting it, went away for a sec and when I came back I also got this black screen with some flicker and a static noise...
will now try to charge it over night before trying again...
Nexus 7/Google problems
I received my Nexus 7 on Aug 21 after hearing the rave reviews. It didn't come with app for a camera, so I downloaded one.
The camera didn't work. I re-booted it & it worked this time. Downloaded Skype - whole reason for getting the tablet - to stay in touch with family that is far away. Tried to Skype - camera wouldn't work. Rebooted - worked this time again (getting tired of having to reboot for something I want to use to work). On Sept 2, sent message to Google inquiring about camera & app I downloaded. Only response - "thank you for contacting...blah, blah, blah - check out Q&A." All along, the tablet would shut itself down & reboot randomly (battery fully charged sometimes). On Sept 13, I shut it down & charged it. After a full charge, I tried to power it back on. Tried again several times that night & then the next morning. Called Google (who I bought it from). Told them I didn't want a piece of junk that wouldn't work. He told me it was past my remorse period. (The only remorse I have is buying their piece of crap instead of a reputable one.) I finally did get it to come back on, but camera hasn’t work since even after a complete factory reset. Any way – in order to get this one fixed, I have to “buy” a new one, then send back the old one & be reimbursed. Is this a legitimate business practice?
hi,
since today i have the same issue. did nothing special, just swichting from g currents to chrome. stock rom, no modifications, not rooted, everything original
n7 suddenly had a black screen(battery was at 28%). nothing worked, no powerswitch(10-30 secs). when connected to original power supply and cable, it boots up.. google logo .. glowing X.. lockscreen. then, approx. 30 sec later it turns off again(screen black). usb cable still connected. after some time it comes up again.. and repeats the procedure. after some cycles it stops, and when i reconnect the usb calbe it starts over again. sometimes, before it turns black, it shows a flickering screen and sometimes fizzling sound.
any suggestions?
I had this same issue right after the 4.2 ota update, after leaving it on charge overnight it seems fine now after a couple of discharge / charge cycles
Its like after the update it was over estimating the battery level

Same thing!
I have a completely stock Nexus 7, and the EXACT same problems are happening to me too! The first couple of times it happened my tablet would reboot normaly. But now, my tablet won't boot up at all. Any suggestions on what I should do? Also, remember, I have no mods installed.
Happening to me too.My N7 shut itself down because of low battery a couple hours ago and I haven't been able to get it to boot since. When I plug it into the charger it shows a flickering screen like a tv with no signal but with less white flickers. I've tried multiple chargers and cables but I could only get it to boot up a couple times and both times it did not show that it was charging even though it was plugged in and the battery was at 0% so as soon as it boots up it shuts itself down again because of low battery.
So now I've got it on the charger, screen all a'flicker, waiting for it to get a charge but I've got a feeling its not even charging because, like I said, the few times it has booted it showed the battery at 0% and not charging.
I guess I'll try to leave it alone for a while and see if it will start up after being plugged in for a bit.
EDIT: I let it sit there and charge for about an hour or so (with the screen flickering) and I was finally able to get it booted. It said it only had 3% battery but now it seems to be charging as fast as usual.

Yup... I've let mine sit there turned off and charging over night... helped!
Just had a problem with the Nexus 7 not charging when battery was likely fully depleted. Putting a charge cable in was automatically booting the Nexus 7 up and wouldn't charge shutting down right after. Loops going on and off. What I did was plug a charge cable in and hold power+both volumes and now I believe I am charging at the bootloader screen. It stays on so I will leave it like this and if it doesn't resolve the issue I will try recovery once it is charged.
I've just started having the same issue. Has happened twice when battery gets to 8%, suddenly jumps to 0, shuts down, then after a few seconds restarts itself. Gets to home screen for a few seconds, battery showing 8, then jumps to zero, switches off and has flickering blocks on screen with static noise. This keeps repeating, only way I have found to solve it is to load into bootloader, then select power off. Device charges normally then and once charged works fine. I am unlocked and rooted but running stock 4.2.1, think I'll just have to return it for a warranty claim.
Based on what you experienced, the lesson here is your device can't handle the GPU over clock of more than 446mhz or it will do some crazy stuff.

Twice yesterday my GT screen went blank. The tablet isn't dead because I can see the backlight on at about 10% brightness. Gives off an eerie gray tone to the screen.
The screen and volume controls do nothing to revive it. However, holding down the power button for about 20 seconds turns the unit off. From there I can reboot.
One of the times happened during the night while I was recharging the unit. It locks the unit up so tight that the charger stops charging. When I unplugged it from the charger and rebooted it in the morning it only had a 42% charge.
Any idea why this is happening? Since it affects charging it appears to be hardware related. Can a software hiccup cause the charger to stop charging?
If it keeps up I may do a factory reset to see if that solves it.
Anyone else having this issue?
Sorry but I haven't had anything like that happen...but I wouldn't tolerate it for more than a couple days.
out of juice ?
Are you using USB charging or the wall charging plug ?
There's a BIG difference in charge .. USB trickles and once the screen is on or you're downloading .. it discharges ..
This has happened to me a few times too. I figured it was just some odd bug.
I haven't experienced this on either of our tabs (both are 16GB (retail) a white and a gray both rooted nothing custom as of yet/ both have locked bootloaders)
Probably not relevant, but I see 2 people have posted this experience. So I ask are either of you rooted or using custom kernel/rom, 16GB/32GB?
This happended to me a couple of times:/ actually happened 2 hours ago. I realized within an hour so only lost 30 percent. I hope there will be a fix with touchwiz ux, even though i don't want to update it to touchwiz, I might have to
This has happened to me, and I am not rooted.

Not rooted and I only charge with wall charger.
Someone asked if I was rooted, I am. Was running stock kernel and rom the first few times this happened though. Only charge with oem charger, although I've only seen it happen once while on charger.
Sounds like it's shutting down but not completing the power-off.
When you power off the tablet - you'll see it do the same thing - it's the backlight that's still on.
If you have access to the android dev tools/adb - use: adb logcat and see if there's any useful output about what's happening.
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!

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.
So I woke up this morning and went to charge my nexus 4, which had around a week of life, only to be greeted with a flashing red light on its LED. It was working perfectly fine up until now, but now it doesn't turn on, it doesn't do anything if I try a hard reset (power + volume down) and charging it with via USB or AC only shows the red flashing LED, with no charging icon at all.
I have absolutely no idea why did it decide to spontaneously die, it didn't even leave the house yet because I was too paranoid I would drop it Is there anything I can do? Any ideas? It looks like getting a replacement is my only option but I wanted to ask you guys if by any chance there's anything else I could try.
have you rooted it or flash anything into it? Overclocking it or something? what have you done to it in the period of a "week"?
Nevermind, I managed to boot into recovery mode after pressing vol.down+power for about 40 secs while plugged to AC. It looks like the battery depleted completely and that was causing the red led — why did the battery go down to 0 while the phone was off is completely beyond me though. (FWIW I did not root the device, didn't flash anything, and didn't overclock it)
I had the same thing happen to be just now. Yesterday my battery died at 2% so I shut it off. I didn't charge it that night. Today I went to plug it in and I got a red flashing led. However after about 3-5 minutes of the charger the regular white charging battery symbol came up on the screen. I think the battery was just really dead.
i got my n4 today, had an gnex before
so i unlocked my phone, rooted and installed cwm
i flashed xylon rom and trinity kernel any 10, and everything was fine, like it was on my gnexus
after a couple of hours i pressed the power button to unlock the screen but nothing happend.
phone seems to be dead, pressing power button for 10 seconds do nothing
when i plug it into charger, the led is blinking red all the time, but phone wont turn on
do you think the device is broken?
i am really ****ed up, now wtf is the quality of that?
used it for 3 hours and its broken?
any idea is welcome..(
Nexus 4 DEAD... possibly not charging.
I have this exact same issue... but trying the volume down+power key or trying the power key by itself does not do a thing. The phone will only turn on for a couple of seconds and then die. I have been trying to charge it for a couple of days now with no luch.
I am overseas and just got my phone, which was thoroughly tested by my brother in the US, but it has been off the charger for a couple of weeks until it got to my hands... Is there any reset button or anything else that I can do if I open it???
Please, sending it back will be a major hassle, thank you.
As long as you are properly charging from a source that can provide at least 1.2A, you should be able to charge the phone back up.
Make sure you're not using an Apple charger, charging from a computer, or charging with a wall adapter that is rated below 1.2A.

Perhaps a kernel related problem? Phone is still very new, devs might have to sort out some shady stuff going on. There will and can always be a certain danger when flashing custom kernels, especially with a device that new.
This just happened to me right when I was demo'ing the 8GB to a buyer since I'm selling it back as I was able to order a 16GB on the last re-offering from Google, (so I don't need two Nexus phones). Hands were sweating when it wouldn't power on, so I grabbed my charger, plugged it in, and then it started flashing a red light. Eventually it turned on after about 5 mins, finally. Battery graph showed 90% charge before it turned off, then 0%, then started back now at 10% charge. This was after powering it off and leaving it in the box since only Tuesday.
Really strange issue... I actually remember something similar happening to my Mom's HP Touchpad a few months back as well. Had to plug it in for about 40 mins after she apparently turned it off and let it sit for a couple weeks during which time it discharged completely. Guess this is the bad part about non-removable batteries lol. Though my iPod touch 2G does sit here with next to no charge and it always powers on without fail.
Happened to me just a few minutes ago, luckily got it turning on again. Weird.
Im using franco kernel and now im scared thanks to this thread...
Which version you have? 8Gb or 16Gb? 14 nov or 14 dec?

Same issue here.
I didn't fina a solution. I've kept the phone connected to the charger for a wole night but it's not booting anymore. I'b only able to enter in fastboot mode pressing vol down + power and connecting it to PC.

This happened to me about 3 days ago while running Antutu with franco kernel r19
My phone completely depleted its battery all the way from 98%. I was able to recover it by connecting my charger for 3 mins and powering on the device with the charger connected. I let it charge for about 10 mins(It refused to charge above 3%).
So i disconnected the charger and restarted the phone. Lo and behold, my battery was back to 98%..
I have been reading lots of threads and i don't seem to be the only one that experienced this issue while running Antutu. Although i have run Antutu multiple times after restart and the problem has not replicated itself..
At first i thought Franco kernel was the culprit but this also happened to people who were completely stock..Leads me to believe that this could be a hardware issue...Lg and Google better figure out what is going on because this could lead to bad publicity and furthermore push people who are currently on the fence regarding a purchase of this device further away.
I have the same issue since this Monday. I still cannot power it on or access fastboot mode.
It happened after I updated to Franco R20 from R19. I still run stock and never OC'ed.
How can I unroot and lock the phone without being able to access fastboot or bootloader?

Here is my problem. I have a Nexus 4 that constantly powers off. And by power off, I mean as soon as the Nexus 4 boots up into the OS, the phone starts the power off sequence.
What I've tried so far was:
- in recovery did a factory reset, wiped both the data and cache partition.
- tried reloading the official nexus 4 firmware. Tried the 4.4.4 and 4.4.3 image
- used fastboot to load up a custom recover only to realize there is no rom on the phone itself to install from so that's out of the question pretty much.
- I tried the adb sideload but the computer doesn't see the nexus 4. the computer however sees the phone when it boots into the OS but the phone starts the shutdown operation as soon as it loads the start screen.
If it's hardware issue, then I guess there's no point in trying to fix it. But if it's only software related I want to at least try to see if it can be saved. lol
Any suggestions?
Well I know this happens when you have 0% battery
maybe your battery isn't charging?
Try booting with your N4 plugged and leave it plugged so 5 minutes, check your battery status and if it's ok unplug it and cross your fingers.

I thought about that at first. but according to twrp the battery life was above 70% and can run on battery perfectly fine. The phone doesn't actually belong to me. She gave up trying to fix her problem and got a new phone. I just got curious and want to find out what is causing the issue.

I left the battery charging all of last night just to try it regardless of what the status said. It was hovering at around 70-80% according to TWRP before I plugged it in. It actually made progress today. The phone booted up. So I put in LPV just for the fun of it. The first time it booted up into LPV, it was doing the shut down process as well. Plugged it back into the wall for 5 mins, unplugged it and turned on like normal. Went through the set up process.
Left it sitting there for about an hour. Then decided to shut down the phone and restart it to see if that issue would return. Didn't return until Play Store started doing updates. The phone shut down. Powered it back up and it was fine. lol. Battery life right now is sitting at 78% and battery widget reborn is saying the temperature is 39C. So it coule very well be the battery. But my friend said the guy she brought the phone for repairs supposedly changed the battery. lol. So I don't know.

Yeah, sounds like a possible bad repair. Try another thing, flash a kernel not based on stock, like hell's doctor or hell's core. After 4.4.4 there are several issues like boot loops and shutdowns with kernels based on stock.

Well it's running Android L Preview port so it's not running 4.4.4 based rom. At least to my knowledge. I'm going to see how long this last. I suspect they didn't really replace the battery or it could be an issue on the motherboard side not detecting the proper charge level on the battery? But battery life so far on the phone seems pretty crappy. 13% in the last 45 minutes on airplane mode with wifi on.
Hi guys,
My Nexus 7 (2012) turned off(not properly) when the battery level was low and won't power on. I tried a battery from a working tablet and tested my battery in another tablet. It seems like the issue is somewhere else.
These are the things I tried:
- leave it for a couple of hours charging (no battery sign at all)
- hold the power button with/without the volume levels while it being both connected and disconnected.
- tested my battery in another tabled and put a fully charged battery from another tablet
- made sure that the battery is connected
There was one more thing I tried - to press the Power button with no battery inside but the tablet being connected to a laptop via the USB cable. One could hear something like a boot noise coming from the tablet (doesn't happen when the battery is inside)
In December, 2015 I installed a Custom ROM with android 5.1.1 which I found here http://forum.xda-developers.com/nexus-7/development/android-6-aosp-grouper-t3268172/ (the thread was renamed and is now about the Android 6 update) The tablet worked fine for these 3 months but one day when I was checking my email it went off and won't respond to any actions.
Could you please help me to fix it? I'm just not ready to give up on this tablet. Thanks!
Both you and i, same model, essentially, the same circumstances. I also tried every method you mentioned as well. Even down to the flashing of a rom. Same results. I even tried "jump starting" the battery. Not wanting to give up on it. It sits in my closet like that boy in A.I at the bottom of the ocean, waiting... I know that is not the reply or help you were looking for. Just so you know, you are not alone..

Well, that's a good start, at least I am not the only one!
Have you tried to connect your device via USB? My laptop can see a connected device but it can't recognize it and I hear some sounds coming from the tablet when I try to hold the `power` button. This made me think that it can be a display/screen related, so the device works but we can't see it due to the broken screen/display. Don't know how to check that though.
Same here, stock Nexus 7, won't turn on, just switched off one day and won't come back on, have tried everything as suggested above, can't get it to flicker, doesn't even register the power connection with a green light or anything

Well, that's a good start, at least I am not the only one!

Try replacing the screen, just to check. If that doesn't fix it, at least you have a brand new screen!
I'm currently having the same issue, haven't used it in 6 months and when I tried to turn it on, nothing happens

I fix mine,
let it sit on the charger for a hour, then hold down the button for 20 sec
same issue here as well ive had it for about a year and im not able to access anything via my pc google help forums had no answer either, looks like we may be screwed..........
Hi, I just had same issue with my tablet only thing is that I was using it with ~20% of battery, nothing special - browsing the web using chrome, then the screen lit gray and shut off. After that no response either from charger, holding power button for 60+ seconds didn't work either, tried re-connecting the battery, still with no signs.
And then, I tried to plug in the charger and then pressing VolumeDown+Power immediately after connecting the charger. Suddenly got some response, that battery charging icon appeared, and it shows my battery charging, but from 0%. Still waiting to charge a bit until I can try to boot it.
I'll update this post with any news.
EDIT: When I connected my tablet to the charger it had that hissing sound, but after few minutes it stopped.
After 15 minutes of charging I managed to boot my Nexus7 with 7% of charge in it a that moment, It seems to work for now.
Summarry of what I did to solve my problem:
1. Opened the back of the N7 (I used a guitar pick for this) and re-connect the battery.
2. Then plugged in the charger and at the same time pressed VolumeDown+Power, battery icon lit up but went out, repeated step 1, and then step 2 again gave me animated battery charging animation which showed up for like 10 seconds
3. Waited for 10-15 minutes and tried to boot normally. And it works now

Hi guys,
My Nexus 7 (2012) turned off(not properly) when the battery level was low and won't power on. I tried a battery from a working tablet and tested my battery in another tablet. It seems like the issue is somewhere else.
These are the things I tried:
- leave it for a couple of hours charging (no battery sign at all)
- hold the power button with/without the volume levels while it being both connected and disconnected.
- tested my battery in another tabled and put a fully charged battery from another tablet
- made sure that the battery is connected
There was one more thing I tried - to press the Power button with no battery inside but the tablet being connected to a laptop via the USB cable. One could hear something like a boot noise coming from the tablet (doesn't happen when the battery is inside)
In December, 2015 I installed a Custom ROM with android 5.1.1 which I found here http://forum.xda-developers.com/nexus-7/development/android-6-aosp-grouper-t3268172/ (the thread was renamed and is now about the Android 6 update) The tablet worked fine for these 3 months but one day when I was checking my email it went off and won't respond to any actions.
Could you please help me to fix it? I'm just not ready to give up on this tablet. Thanks!

Honestly, I do not think it is the battery, I can see the Charge signal, and the Battery is showing 1,784 VDC tested unplugged and disconnected, my smart young co-worker seems to think POST is failing, I still never see a "Charging" indication.
Does anyone know , Is there a fail safe, say the battery is disconnected, and usb charger is plugged in, will i just see all 5VDC at the sub port, ?
I never see a screen flicker, DEAD battery sign, nothing.
co-worker, tried some things that made sense when he explained what he did, I would have to agree with him.
Now it is rooted, 4.x something I forget, Never went to 5.x did once early and did not like it, Back stock, ran 2 days no issues, Rooted again, 4.x still do not remember, worked great 3-4 months, Sons ran it to DEaD and that was it, put it up for 90 days or so, wife got new tablet, kids have Fire each, and here i am tabletless, CRAP, did not want to throw to much $$$$ at this thing, nor did I want to buy a new one.
Samsung Tablet here we come.
any body want this Nexus 7, it is a 2012 model.
