Before I owned the Note, I owned a S2.
I was impressed by the fact that it is the smoothest Android phone on the planet at that time.
But one day, I was using my computer to do some stuff.
The phone was just beside me.
I noticed the phone's battery is going to kapoot.
I even seen it going to sleep.
Too busy, I didn't notice the phone actually died.
When I was about to use my phone, it wouldn't wake up.
I tried every single method to turn on the device, but it wouldn't work.
I even put my friend's S2 battery, but it wouldn't turn on at all.
Left it for a week in the charger but to no avail.
So in the end, I sold my DEAD S2, and bought a Note.
And yesterday, I left my Note to charge.
This morning, I tried to wake it up, it wouldn't turn on.
But miraculously after removing the battery for five minutes
then putting it back, it turned on.
So yeah I almost swore I wouldn't buy another Samsung.
I'm still in Samsung camp and in love with my Note.
PLEASE DON'T FAIL ME AGAIN.
That's my story, thank you.
Cool story bro

I experienced the same thing with your S2 but on my Note. I ended up with having a DEAD Note. I sent it back to the service center for repair and hopefully for replacement since it still has warranty. I had to admit, I haven't tried to remove the battery on my Note for five minutes before putting it back in.

Check out this thread: My phone suddenly shut down I think your phone may not have died, but the screen just wouldn't turn on. A kind of coma-like thing, rather than a sleep of death. It's been happening to a few of us and seems to be benign, so far. It's happened to me just 4 times in 2 months. One of the times I was able to get the screen to turn back on when pushing the home, power, and volume buttons randomly. A battery pull always works, but rebooting by holding the power button for 10 seconds also works.

As I mentioned in the other thread, I did every button combination even after a battery pull. I even tried to use a different battery altogether but to no avail. I'm just curious, how long did you have to wait before you put the battery back into the phone after pulling it out?

I'm very sure it's not a coma. It's permanently dead. Used a JIG, it wouldn't turn on either. Left it charging for a week without removing, wouldn't turn on. But if my S2 didn't die, I wouldn't be owning a Note now.

Well you know what they say, either they have the same disease or the same doctor!! .
On a more serious note though, I'm happy everything ended well.
Maybe there is some power spikes at your end? Having both phones the same problem seems too much against the odds.

No one has the same problem with me? Power spike seems too much to be the cause.
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.

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.

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.
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?
bump
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.

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.
bump
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
Sent from my Nexus 7 using xda premium
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.

Pretty self explanatory. It was dead for a couple of days, I put it on the charger for almost the whole day, now I get no picture, but the backlight is on when I hold the power down a minute. I bought it at walmart, doubt I have the receipt, and didn't get any extended warranty. Is there a way to fix this issue?
I've got the same issue. I was playing Tupsu, when suddenly my n7 rebooted and there was no picture, just semi-strong backlight. When the tablet died, the battery was about 45-50% and I was charging it through notebook's usb port (original n7 cable). I tried to turn it off, but pressing and holding the power button only made it reboot once again (i assume it was rebooting, since the backlight was turning off and on in a second). I've tried it many times, with tablet plugged into wall/usb charger, and even with the power+volume up/down combination, it would still behave the same way. However sometimes after rebooting there was not only backlight, but also thin, mostly white, horizontal lines, appearing in random places of the screen (appearing and disappearing after like 50-100 ms). It would stop only after a reboot, and happened every 5-10 reboots.
I've decided to let the battery die to see if it changes something, and as you may guess - it didn't. It died estimately after 2 or 3 hours. Now it's all the same, except for when I plug it to the charger, there's only a very low backlight (still no picture) and it's blinking... It also makes this continuous "electricity-related" (sorry, I don't know what's the word to call it ) sound. After I press the power on, or let it charge for 1-2 minutes it boots up, and there's just a semi-strong backlight, like earlier.
It's a refurbished 8gb n7, which I got 5 days ago from the polish Asus online store. Oh, and the speakers weren't 100% fine, if it changes something. They were fine at first, but after i plugged headphones in and out, they were making cracking sounds when the volume was over 50% or something like that. Is there any hope I can fix it myself?
edit: the android ver. is 4.2.2, not rooted
the device is getting warm on the left side when being charged, or just turned on...
Have you tried pulling the battery for a couple of minutes?

Nope, i don't want to mess with the hardware since i've bought it only few days ago... I'm afraid it may leave some traces of being opened, i'm not willing to take the risk.
You won't leave a trace pulling the battery. Just use a guitar pick or credit card and run it round, the back comes off very easily.

Yeah that is definitely worth a shot. Just pull the battery.
Ok, I did it.
Didn't change a thing >:[
btw. I didn't actually pulled off the battery, i've just disconnected it - it doesn't make a difference, does it? and another thing - the backlight was turning on immediately after connecting the battery... with these randomly popping horizontal lines.
I've got this too!

I've got this too! Pulling the battery does nothing. Last time it just fixed itself, now nothing.
Worried I'll have to take mine back.
How did that 'fixing itself' happened to you if i may ask? And how long did it last?
Your tablet has gone into sleep mode to protect the battery from further damage due to its low level of charge. What you're seeing is by design, as complete discharge of a lithium based battery is bad for it. You should never, ever, let it sit dead for a couple days. If you do discharge it to the point of shutdown again, immediately put some sort of charge on it, as waiting to long will cause the battery's protection circuit to fail completely. Best practice is to not let your device go to the point of shutdown, but rather to plug it in when not in use. Your battery will have a longer lifespan.
Plug your N7 into the charger and immediately press power and volume down to get into the bootloader. Once there, use the volume key to scroll to Power Off Device and then press the power button. After it powers off, unplug it and then plug it back in. It should then charge normally.
You seem not to have read my posts at all. When it happened, the battery was about 45-50% and it was plugged into the laptop's usb port. It suddenly rebooted and there was no more picture, just the backlight - and it lasted for like 2-3 hours (maybe even longer)! Can a completely discharged battery power the backlight for this long? After it turned off at last, i put it on charge and i've tried the power+volume method and it didn't do anything (btw. i already wrote about it)... then i let it charge for like 5-6 hours and it didn't change anything except for the fact, that the battery was evidently charged, because the backlight again lasted for few hours.

Actually, I was addressing the OP without realizing that this was a zombie thread.
To answer your question though... yes, when in sleep mode the battery can still turn on the backlight and keep it powered for some time due to the low power requirement of a black screen. Many users that have found themselves in sleep mode actually have their tablets enter into a prolonged cycle of bootloops. From the sounds of it, your device seems to have, for reasons unknown, put itself to sleep.
Anyway, I digress... I know you've stated you've tried various combinations of the power and volume keys. Have you attempted holding all three buttons for approximately 30-40 seconds while the tablet is plugged in? If it that will force it into the bootloader, you can follow the steps that I posted to get it up and running again. If not, then it seems your best available option is to seek an RMA from ASUS. Given your speaker issue, I'd send it back regardless- you shouldn't be expected to deal with battery and speaker issues after only five days.

Yep. Many times. And even longer than a minute.
Anyway, I'm going to contact their crappy support. Thanks everyone for trying to help.
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!
