Started last night. Phone would just shut down all by itself. Thought the battery was dead so I tried to charge it. No LED showing charging. Took the battery in and out several times till I finally got it to boot. Battery showed about 70% or so. Used it for a while, then BAM, shut off again. Placed on the charge got an LED this time, red. Wake up this morning and try to boot the phone. LED is green and looking good.
Worked most of the morning, then it was dead when I took it out of my pocket. So I go and get a new battery for it. Does the same damn thing. I am running CM 5.0 or so on it. Tried charging both USB cable way and direct to the wall.
Now I have used recovery screen, right when I go to wipe it dies out.
Will only boot if I take the battery in and out several times and finally will get G1 screen. Sometimes it will reboot itself, other times the screen just fades away.
And Ideas?
BTW, nothing happened to it recently. But it did get wet about 8-9 months ago. I stuck in a ceiling fan to dry it out for 2 days. Has worked perfect since that day until last night.
Update:
I was able to flash Zdonut 2.5, get to the sign in screen, goes black and reboot
New battery fully charged.
I even tried an old back up with same symptoms.

I have got the same symptoms, my screen fades out and the only thing I can do to power it up again is to remove the power plug and the battery.
Nothing brutal has happened to it, it started after I installed CM5-test1 on it but I have no idea if it's related or not.
Now it's living less and less time, I'm able to boot to recovery but usually not to boot into my OS (tried to reflash superD).
I think I need to get it to warranty, but for that I would like to restore my Orange Rom, but I'm afraid to do so as I have the newest radio, the haykuro SPL and a phone that may power off at any moment...
So last night at kickball, I sent a text to my wife. The next game, I wanted to see if she texted back, and my phone was off. I didn't remember the battery being low, but thought that perhaps it might have been. When I got home I plugged it in and got nothing. I tried to do the Power/Camera/Reset to see if it would go into bootloader; again nothing. I left the battery out all night, put it back in this morning, still nothing. I've tried usb charging and wall charging as well, with and without the battery. Nothing turns it on... is it done for?
Same thing happened to mine recently. I know the battery was low, and it turned off because of that. Never got it to turn on again.
The only sign of life mine shows is that the red led will turn on if you have it plugged into a charge with the battery out. Other than that, it's a paperweight.
Never got mine working again.
I took mine apart, and somehow got it to turn on again... it was a messy process.. something must be shorted out. Going to have to get something new soon.
i have just the same issue with moto milestone ... i am sure that the battery is fully charged, cause ive charged it with another milestone ... but that one simply won't turn on ... tried different combinations of sd/simcard/battery on and off .. still the same ... Any help would be highly appreciated.
same issue here, mine just stopped working yesterday, battery was fine, i did a soft reset randomly, and then it wouldn't turn back on. Both the talk and end lights are on, that's it..
Mine does the same thing since it was dropped in water. It had'nt been turned on for 2 years since I decided it would work! It still does the red light thing sometimes, but all I got to do is remove battery, try power button and repeat the process until it works. Try it out!
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.
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.

So I've had my Moto X Pure (XT1575) for almost two years now, and it's been through hell and back with me. A few months ago, I replaced the screen because of the hot spots the screen had since I've bought it, at the same time, I replaced the battery, the frame and installed a wooden back cover. Yesterday, while I was using it, the phone died and started trying to boot itself back up. I thought it was a sudden turn off, like when you have 30% and it dies because the battery is old. So I let it in the charger for a few minutes just so I could turn it on; but it didn't, it turned on for a split second, showing the bootloader unlocked screen and dying instantly. Luckily I managed to boot it once, and what was weird is that the battery showed 50%+ charge and was charging normally. I went to sleep and let it charge overnight, now it flashes the white led as if the battery level was too low to turn on. I suspect it's a bad battery, but maybe it could be something else. Any help is appreciated.
UPDATE: I've tried to boot the phone again but it doesn't want to do it, it just flashes the bootloader unlocked screen then dies, it's like a bootloop but weirder. Tried to get to the fastboot menu and it lets me, it says "battery is low" in the battery status, which is weird, since it said "battery OK" yesterday.
NVM, I opened the phone and disconnected the battery and put it back on and the problems fixed itself
