before this, about 1 mo ago I got a problem.
it takes restart whent main speakers volume gets at 80% with any sound. so I had to keep silent the phone or set below 80%.
But today I discovered that it gets turned off whenever the charging stops. after that, I tried to turn on but again turns off after boot logo. there was no low battery signal. I checked several times and it happened every time.
I never had any battery issue.
please help me where is the actual problem and how to solve that!
A bad c port PCB can cause weird behavior in Samsungs beyond charging.
If you did any major firmware upgrades it's time for a factory reset.
Otherwise clear the system cache.
If the boot loop garbage continues, factory reset.
The original flash may be corrupted if that doesn't work... or it's a hardware issue, a definit possibility.
If under warranty it's time to send it in.

Hi everybody..
I discovered the problem few months ago, when my HD2 shut down spontaneously ! I thought for a while that the battery is empty, even though i was charging it in the same morning, when I turned it on, it worked but with a reduced battery reserve and a previous date and time..
that problem repeated infrequently, until last week, i discovered my HD2 stuck at the boot screen (the white screen with htc written in the middle) and it was unresponsive until I removed the battery, then i rebooted the phone and it was installing windows for new, as if I did hard reset.
when the phone was connected to pc for backing up my data, it became stuck for new, and i had to remove the battery , but it made an auto - hard reset when rebooting.
I thought it might be due to charging from USB , so I repeated the backup process while disabling that choice, eventually the process completed without problems, but when i rebooted the phone after installing an application, it became stuck again and the tragedy happened for a second time..
I tried to install another ROM but the problem persists to happen, it was not related to installing new application .. the last time that happened was three days ago when i was emptying the battery, so i charged it while the phone is off and when i turned it on it made a self- hard reset ! after that it never happened again. but now the problem is when i turn the phone off and remove the battery for few seconds the time is going back and the battery reserve is reduced/increased to the last time i removed the battery ..
Is that problem related to the end of life for the battery ? or it is due to the charging circuit ??
control the 3 pins at the battery
try a new battery (not expensive)
if that didnt solve the problem, go to a repair-shop and explain the problem again, may they can help u
Hello guys, this is my first time posting up in XDA and I am encountering a very weird problem with my N4
Disclaimer, the following is a long write but please bear with me and give a read.
Here's my problem after flashing the simple asop 29/5 build for mako. I come from same rom build 21/5 but i did a clean flash for the latest build. As soon as success flashing the latest build with gapps, then as usual will proceed reboot the system. Just right before the boot animation, the phone immediately went dead. I am sure that the phone is still left with 50%+ of battery at the moment.
Anyhow, I decided to plug it into charger. And voila, the phone now able to go through the boot animation and everything just fine. After setting up and restoring backups, I unplugged the charger, its 75%+ on the battery. Within 10-15 seconds, the phone immediately go dead again. I hit the power button and tried to boot up. Again, right after the Google logo screen, the phone went dead.
Commonly this indicate a problem with the battery. Yeah, but I went into recovery twrp and disabled the screen timeout & max the brightness. Guess what, surprisingly it lasted more than an hour which proves that this wasn't battery fault.
What had I tried so far, is just switched off the phone and plugged into charge for 2 hours. And obviously it doesnt solve the problem. I am backing up all the data at the moment and plans to drain the battery all the way down just leaving it screen on at recovery.
Anyone who know what happening with my n4 or encounter similar experience, please feel free to share the solution. Many thanks

Have you tried making a clean wipe and trying either stock or another ROM, to see if it works then?
Your test doesn't prove it's not the battery's fault. Flash back to stock, see if the problem persists and if it does then you know you have a hardware problem. Could be the battery.

Hello, much appreciate your reply. I flashed back to stock 5.1.1 now and yet this problem is still persisting. Thus pretty obvious thats an hardware faulty.
In another forum, a guy with Nexus 7 had similar situation as me, and he suggests that its the battery or the circuit board at the charging port went kaput.
Guess nothing else I could do right now, gonna send in the phone for repair and hope the bill wont cost as much as a used nexus 4
happened on two different roms (RR and LOS)
battery < 10%
plug phone in to charge overnight (wall outlet)
find the phone bootlooping in the morning (probably after 4-6 hour charge) maybe not bootlooping, but stuck on boot animation
unplug, hold power to turn off and turn on
phone boots, but all app data has been wiped
really annoying problem that i hadnt had in over a month with RR as daily driver. switched to LOS and just happened again
I have a feeling this is hardware related now... and not necessarily related to the low battery state when plugged in... seems like battery charges up and then this occurs, but im unsure how to diagnose the issue... google has failed me on this one :crying:
Finally figured this out, hopefully helps someone else
After phone has rebooted on its own and is stuck on the boot animation, unplug the USB adapter. It will eventually boot and then reboot again on its own. Once it does boot the second time, it will be fine
The wiping was happening because I was holding down power to force the reboot. Should not do this
Very surprised that I am the only one reporting this on this device and that no one else has even heard of this. But ok
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 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.
