So I was using my flyer in bed and fell asleep, I use a cover for it so I don't think it overheated. However, in the morning I noticed it was turn off and it wouldn't turn back on.
Things I've tried:
1. Holding power button 5, 10, 20, 50+ seconds. Flash red light at 10 seconds, nothing more.
2. Holding Vol- and Power button, 5, 10, 20, 50+ seconds, same thing.
3. Charge with HTC Flyer's wall charger overnight. (repeat step 1, 2, same thing)
4. Charge with Samsung Captivate charger overnight. (repeat step 1, 2, same thing)
5. Unplug battery 5 minutes, replug and repeated step 1, 2, 3, 4. same thing.
at one point in between my power light started flashing red/green after holding the power button for longer than 10 seconds. However it doesn't do that anymore.
I've also tried plugging it into the computer to see if adb would detect it, but nothing (Although I'm not sure if I set it up correctly).
The only sign of life is the single red flash when holding the power button. There is no sign of life from the screen. Is it time to give up?
edit: forgot to mention:
rom = Leedroid 4.3.0, been using for probably around 5 months with no problems nor had any signs of issues.
If there's any other information I'm missing please don't hesitate to ask, I'll answer as best as I can. I really hope it didn't just randomly die on me.
I've tried following http://forum.xda-developers.com/showpost.php?p=20923118&postcount=11
However, of the 2 phones I've tried (an LG flip phone and a pantech flip phone) one tells me to use genuine LG battery and the other tells me to check the battery.
How likely is it that my battery actually died? I used a volt meter and the battery itself would give me 3.48v which I'm not sure if it would mean a faulty battery or just one that has no charge.
Manually charge up flyer battery. ppl had this problem befoure with completlly discharging battery thats why its always recomended recharge it at 10%. There is a guid in this forum about how to do it.

I havent used the tablet for about a week or so and initially thought the battery was dead. Left it on the charger for about 3 hours and tried booting it but nothing.
Held the power button for 30 seconds and again nothing. Tried factory reset menu (power button + vol down key) and again nothing.
Tried the power button + touching screen: hxxp://mojocode.com/content/samsung-galaxy-tablet-101s-wont-boot and again nothing.
I also took the back plastic out and "pulled out" the battery and waited about 30 minutes to put it back on and still nothing.
I was on official release of ICS and now im all out of ideas,
Is it "Officially Dead"? any help would be appreciated.

If you open the tablet, it's easy to check your battery with a multimeter.
if your battery is discharged bellow 3.3 v(for Li-Po)/cell then you can't recover anymore, it's dead.(as you say you don't use it for a week)
Check your battery voltage, and if you can try to boot your tablet with another battery.

How do I test it? I dont know which is negative which is positive.

If you have digital multimeter, doesn't matter because you'll read negative value of voltage if connect multimeter in revese way.
i dont know how many cells you have packed in your battery, but if you can read from battery 3.7v means 1 cell, 7.2v means 2 cell...etc
You will see (if you have 2 cell for example) 3 wires because is 2 cell in series, and your tablet charge them cell by cell, not charge your cells in series!
Measure voltage betwen 1-2 wire and 2-3 wire.
You must see a value between 3.3-3.6v on both cells.
I hope it helps
What happens if you connect it to your PC then hold down the power button? What kind of device shows up if anything?
Just curious if anyone out there has taken the back of their DNA and unhooked the battery as a form of resetting the phone.
Here the backstory. I was testing out the VRtheme system and had a bad flash....like a fool I attempted to reboot the phone instead of flashing back to where I was. It should have only messed up the systemui.apk, but as of now my phone is completely dead. I've left it on the charger overnight, held down all button combos I could think of (there are only 3, so its not a lot of combos)...and I get nothing. Capacitive buttons don't flash. Charge light doesn't come on when plugged in.
So what I was thinking is that a battery pull for 20 minutes or so normally "resets" phones (with removeable batteries of course)....so maybe I could remove the back cover and unhook the battery for a while. Thoughts?
Not sure about the battery pull but I've always just plugged it into the charger then pressed and held power+volume down for as long as it takes (about 20 seconds maybe a little longer). Should reboot in to the bootloader.
I'm hoping that will be the case when I get home from work today. But up until now I haven't got it to respond to anything.
When I first got mine it seemed like I couldn't get it to come back to life unless it was plugged into the charger. Later it seemed that I just needed to hold down the buttons like I said above. YMMV.
As many of us are aware, there is a issue that can occur with a Nook Tablet going crazy with phantom touches. Essentially it looks as if you are tapping on the screen when you are not. It usually happens very quickly, one minute ok, the next everything is getting tapped all over the screen. This can cause data loss as the device thinks you are touching the screen. For example a file you were working on may abort before saving as it thought you hit "close".
I have been bugged by this issue on and off. Some people replace batteries to fix the issue, and while that will fix it 99% of the time, there is an easier (and cheaper way).
The problem appears to be the newton loses battery calibration. There has been talk in the past of deleting the battery file via CWM or other Android app that deletes this file (or even doing it manually with a file browser app, which may need root access). This battery file is only data since the LAST time you charged the device. Not the calibration data. And this file is deleted automatically everytime you plug it in to charge.
How I fixed it
After a lot of research I found that many Android devices there often a way of recalibrating the battery charge system. The steps are:
1. If you get phantom touches hit the power button as fast as you can to put it to sleep ande prevent anything occurring you might not want (aka a file deleted you wanted to keep etc).
2. Charge the battery to full, until the green light is lit on the charge indicator located on the Nook Tablet charge cable
3. Unplug the device from the charger
4. Use the Nook Tablet for 20 minutes with a high drain app (aka watch a video)
5. Plug the Nook tablet back into the charger and wait until the light turns green again.
6. Repeat steps 2-5 several times. I would suggest 3 or 4.
7. See if you get phantom touches again when the Nook Tablet power gets low. If you do try steps 2-5 again several more times.
In my experience after a few times of this, I no longer had the phantom touches issue.
Why it happens
I am not sure all the details as to why, but one time I do know for a fact that one time it happened after I had the tablet on the charger with a full charge (I had not got around to unplugging it yet) when the power to my home failed. It came back on a few minutes later but that night when I was using the device I got phantom touches at about 50% power left. Which I never had before. After doing the above method it is working fine again even down below 15% power (which I never let it get that low normally).
I suspect that the power failure caused the charger system to recalibrate and since the battery was already at full, messed up the whole system. I also would NOT leave the Nook Tablet on a charger for long periods. If it sits at 100% for a long enough period it is possible for the battery to drop down a little and start charging again. This could start a recalibration again, bringing back the phantom touches issue.
I have not posted until now as I was not certain what fixed it before. If it was the charge to full, use for 20 minutes, then charge again method or turn it off then charge method worked. I tried several before and wasn't sure which one worked. Now I can say the put to sleep, charge, use, charge again method does work. But don't turn off the device then charge if you can help it. If the Nook tablet is powered all the way off (not sleep) doesn't seem to do a battery recalibrate. Or at least my best experience is to plug it in while in sleep mode, charge to full (green light), use for 20 minutes, and then charge again.
Sorry if this has been posted before. But a quick search didn't reveal any hits.
UPDATE:
Upon further tests, often powering off the device fully (holding power for 30 seconds or pressing for 5 and saying yes to the popup to power off), then plugging it in, letting it turn on and charge to full will fix the problem as well.
Long story short. Another Z compact down. This time it's my Z5C.
Unrooted Z5C E5823. I flashed some marshmallow from xperifirm (build 32.2.A.5.11) some 8 months ago...
Description of events:
Just finished texting. Turned screen off. I go to turn it on again but the phone turned off, because pressing the power button doesn't do jack. Long press it and doesn't turn on.
... great.
Volume down + power button and it turns on after 3 vibrates. Battery level plummeted from ~70% to 20%. So I just put it on a wall charger and wait.
Some 20 minutes later, I'm surprised to see that the phone is still at 20%. So at this point I'm sure something is very wrong and I start browsing for solutions. Nothing worked.
The only thing I didn't do is a factory reset. But I seriously doubt it's a software problem.
So I say "screw it" and I unplug it from the charger and start using it normally. At some point the phone turns off on itself so I have to do the volume down + power button combo again. But this time, alas, it doesn't work either. So I try the little yellow "off" button on the SD bay + holding power button. This time the phone vibrates 3 times. Then I turn he phone on again. But this time it turns off after some 40 seconds. Then it began a short power on/off cycle and then remained off. Won't turn on. Like if it was hard bricked. I fiddled with the yellow off button while plugged in on the charger and it turned on again but still won't go past or below 20%. Ever.
I remove it from the charger and go home from work. Phone is unresponsive. PC doesn't recognize it. No key combination works. Charger and key combinations don't do jack. But THEN out of the blue, I sense 3 very faint vibrations (i just kept trying to power it on, I wasn't giving up ) and now the phone is on again. Battery at 20%, obviously. Service menu doesn't have a battery test anymore. How convenient... Battery usage menu is always the same when I turn it on. PAst history is gone, app % use are all the same ratios.
I'm trying to backup my data now. But at the meantime. Phone is on and still stuck at 20%.
So, is the battery dead? Wth is going on?
i have smailer problem
my phone wont pass the 90% . also after factory rest (stock rom\kernel\no root\lockedBT)
still, im not sure 100% is my batt i think is started from android 6 (now im at 7)
also my phone wont pass some voltage also (4.300) was 4.350 when the phone was new with 5.1.1
but in QC2 quick charger its 4.308volt max with 92% so i dont know whats goin on:|
hi,
I had same problem somes weeks ago.
try flash new rom, phone stuck at 20% but seems to have same battery's autonomy .
after a week I changed the battery, now all works fine
I think this is the lithium controller that is dead not the battery itself .
Battery and turn off problem
My Device have charge (50,60,70 or more), unnexpected it show 0% and turn off.
Hardware problem maybe ???
Hello,
I was playing a game on my Black Shark 3 Pro and it just shutoff. Now, if I press and hold the power button, nothing happens. If I plug the charger in, it doesn't charge. The phone seems to be completely dead.
Has anyone else experienced anything like this before and what ended up happening? Is this something that can even be diagnosed if I take it to a repair place? I'm assuming they'll have to take it apart and if they can't fix it, I'll get charged anyway for the work of taking it apart. Is there any hope?
Thanks,
Ben
While this is not normal behavior, here are some things you can try. First, power-cycle the device by holding the power button for 20 seconds, 5 times. Attempt to start the phone by holding down the power button and the volume-down button at the same time. This will start recovery mode where you can perform a factory reset. If this does not solve your problem, please follow these steps:
1) Let your phone rest for 12 hours (do not charge);
2) Charge with the official charger and cable for 6 hours;
3) After 6 hours, disconnect then reconnect your phone to the charger. A low battery screen should appear;
4) Do not attempt to boot. Allow it charge for 1 more hour;
5) After 1 hour, your device should be ready to boot and power-on.
if those methods don't work,give your phone to phone repair place
