My phone was acting normal until now. Today after completely draining the battery I went to plug it in at home. The usual battery charging picture appeared and I thought nothing of it. Then when I tried loading the phone, it loaded as normal till it got to the lock screen, where it showed the battery at 0%. If you leave the phone for a while, it goes back to booting and does the Android Animation for a long time before going back to that lock screen, showing 0% and repeating itself. If you try and login, by the time you get in, it will go back to the booting Android Animation.
I can't seam to get beyond this point. I tried turning off the phone completely, then turning it back on. I tried clearing the cache. Nothing. I am stock standard, not unlocked bootloader. I am on Android 8.1.0 Security Patch January 2018.
Any help would be appreciated.
Update:
Just letting you know it is.. 'fixed'. After unplugging the phone and letting it bootloop few times, it finally registered a battery level that wasn't 0%. It was 96% and as such ran like normal again. That being said, I am worried about this happening again, so I hardly think this is fixed, but just leaving this here for anyone else that comes across this problem. Also would love to hear any suggestions to possible fixes. Incase this was related to the other bootloop issues that cropped up last year, I have set my phone for OEM unlocking.
Save yourself the trouble and just unlock your bootloader now.

I think my wing is beyond saving at this point but I wanted to check here and see if anyone had any suggestions. 100% of the time that I send a text and slide the face closed right after I do that the phone will shut itself off. If I recieve a text or a phone call about 15-20% of the time the phone will just lock up but not reboot. It is totally hit or miss when I reboot it, some times it'll boot back up then freeze, some times it'll boot up and work for a while til it reboots again, some times it'll get stuck in a boot loop. Every once in a while when I boot, the screen will go all fuzzy, almost like a computer with a bad video card. Now I have flashed the rom back to factory, I have done a hard reset, and none of this has fixed it yet. Does anyone have any suggestions?
Before you give up. Try something first. Does the Wing have this behavior if it is plugged in to its charger. If it behaves well when plugged in, then most likely you have a bad battery.
cant believe i didn't think of that already. plugged it in and everything has been fine for a couple hours now. I just ordered a new batter for like 12$, good lookin out, thanks.
This is the second time this has happened. The first time I thought maybe I forgot to turn it off, which still would have been weird since I usually get fantastic battery life. But this time I am certain that this is what happened.
Last night I turned on my Nexus 7 briefly - I had about a 90% charge. About 10 minutes later, I turned the tablet off. Completely off. When I woke up this morning, it wouldn't start at all, which I thought was weird but not too uncommon from other reports I have seen. So I held the power button for about a minute and a half, still nothing.
I plugged in the charger, and sure enough the battery had completely drained. It started charging without any problems, however I am wondering.. How in the hell does the battery go from 90% to completely drained while the tablet is OFF??
Never had this happen before with ANY mobile device.
Just posted this same thing in another thread and what I had to do to fix it. Don't know if its a guaranteed fix until some more people try it. But I'm back in business.
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?
From here http://forum.xda-developers.com/showthread.php?t=2029034
Thanks for the reply.
I'm completely stock 4.2.1, I've never changed anything other than official OTA updates with one exception.
I did flash back to stock 4.1.2 at one point, but then I allowed the OTA again to 4.2
Later OTA'd to 4.2.1
I don't have the tablet with me so I can't check the bootloader but it should be whatever stock bootloader is with 4.2.1
I appreciate the reponse - will advise when I get home after work and can take a look.
Also, I have never had any of the other problems you mentioned. Only this issue (battery drain while tablet is off)
So someone called me about 3 hours ago, and my phone just outright died. Couldn't turn it on - no signs of life, even though I had received a call just fine this morning, 2-3 hours before the random crash. Now I couldn't turn it on, and my first guess was that the battery was the culprit, though it was on charge through out the whole night.
So I pugged it into my powerbank, the phone turned on, but kept kinda bootlooping - where the "relock your bootloader pls" message would come up for half a second, followed by the phone restarting again to continue the cycle. This was without the battery charging animation - straight into booting.
After 20 or so tries to turn on it actually did, and I was able to discharge it past the point at which it crashed - most likely excluding the battery as the issue for now.
What could this be? Could it be a chip that's on its way out (as in about to brick my phone)? Anyone have any ideas as to why this is happening? Or maybe an app to check system stability / hardware test?
Edit: thanks to firefox, for saving the progress of this write up as my phone did the exact same thing after I locked it. My pebble watch vibrated to indicate that the connection is lost and I wasnt able to turn the screen on.
Had to plug the my 6P into my power bank again for it to turn on. Though it didn't do the glitchy bootloop this time.
TLDR: are there any diagnostics I can do to verify that my battery needs to be replaced?
A few days ago, I turned on my phone to check the time and a half-second later it suddenly and instantly shutdown. I was not able to restart it at all. When I got home and plugged it in, it began a continuous boot loop, with only the motorola splash screen displaying, then nothing for a few seconds, then back to the splash screen over and over.
Fortunately, I was able to get to the"AP Fastboot Flash Mode" menu. I couldn't do anything from there on the phone itself though; every option just went into the boot loop again. I was able to get a fastboot connection with my PC and so reflashed the phone successfully.
After reflashing, it went into the boot loop again. I began looking for more solutions online and wasn't paying attention, but sometime in the next 5-10 minutes it made it to the login screen! I re-set up my phone and all seemed to be working fine!
Until the next day. I tapped an app and instead of opening, the phone immediately shutdown and went dead again. Took it home, plugged in, and it went into the boot loop again.
Anyway, I've read a few threads on here and elsewhere that the culprit may be the battery. I would like to have more than just a hunch before I shell out the money and time to replace the battery -- is there any way I can verify that the battery is indeed the problem? I didn't seem to be having any battery problems before - charging and usage seemed fine. I did drop the phone rather hard a few weeks ago, but didn't seem to effect anything (short term at least).
Also, could using a non-Droid Turbo 2 charger affect battery life? I actually got the phone used and didn't get the official charger with it, so I've been using just a random leftover one for ~6 months.
TIA!

Try the apps such as Ampere which shows battery info.
I don't think so Non-Turbo charger can lead to affect the battery life but using a cheap charger does.
my S7edge, with Stock ROM, never flashed or hacked it.
was working perfectly fine.
Last software update package was a week or 2 ago.
Today, the phone suddenly froze while I'm using it, then restarted and kept rebooting automatically in an endless loop.
I tried to force it to go to recovery mood... it would go to a blue screen saying : "Installing updates" and nothing happens.
kept rebooting into safe mode or recovery/download mode until it suddenly just went totally off.
The charger wires were a bit cut lately, so it would give a broken charging lately, not sure if that caused any kind of problems to the battery or mother board.
Since then, I am not able to turn it on again in any mode.
It also doesn't show any indications when a charger is connected.
So right now it is just dead with no signs at all. non responsive to any force power ON nor to charging.
I left it for more than 5 hours now without charging, nothing changed.
Update:
So I left it overnight. In the morning, I connected the charger and indeed it drained to 0% and started being responsive to charging again.
As soon as it charged to 20% I powered it on. It loaded into recovery, giving the no command screen. Then I went on and selected system reboot.
Then it rebooted and Android started, as soon as I tried unlocking it, it froze and started again into an endless rebooting loop until it blacked out again. Now again not responsive.
I will leave it to drain again. Does anyone know what I shall do when it gets to that endless rebooting sequence. It is obvious that Android had a malfunction... not sure what as I didn't do anything new last week..
Is there a way to get it through without factory reset?
Thanks

Bro flash latest stock rom
Solved !
It was already on stock ROM.
After lots of troubleshooting, rebooting in safe mode without the SD card worked fine. I then rebooted in Recovery mode, wiped the cashe, rebooted again normally with no SD card. Then inserted the SD card after.... got a message that SD card is not supported (seems it got corrupted somehow).
Anyways, now it's fine... let's see for how long...
