Droid Turbo 2 Strange Boot Loop - Droid Turbo 2 Q&A, Help & Troubleshooting

Alright,
I replaced my battery today (the battery I replaced drained very quickly) and that is when all of my problems started.

Most people have the issue that their phone is stuck in a boot loop and it just goes to the booting screen and dies - mine is different. My phone was stuck in that phase, however it stopped after a factory reset. It boots all the way to the home screen. Then within five minutes the power-off overlay appears (without me selecting it) and immediately turns off. Then it reboots. My phone is at 4% and is stuck there as I charge it. As soon as the phone has enough power to turn on it does,
I have already wiped my data cache and performed a factory reset.
I have two other working batteries, but they have no effect on this.
I am trying to troubleshoot whether this a hardware or software problem - does anyone have any ideas?
Update #1: So last night I swapped out one of the batteries and it was at 21% when the phone turned on the first time. However, it too started doing the interval shutdown within 5min of being powered on. When I woke up in the morning the phone was drained and would not power on whatsoever - even while charging. So it charges until it has enough to turn itself on and then gets stuck in a boot loop until it dies.
Update #2: Somehow it started holding a charge. After wiping it started booting to the boot loader screen - so I have this to thank. Now it turns on fine, however some dead pixels have started showing up. Also, the current problem is that it randomly turns off - any fixes?

Samsung tab not charging even after factory reset.

Yestarday my Samsung Galaxy Tab 4 stopped charging and when the battery was drained i was not able to switch it on.
while trying to charge, first it would vibrate in very short intervals (twice in a sec) and later it started showing logo but would again shut down.
Somehow on reaching recovery mode i formatted my tab and rebooted it.
Now while opening for the first time after rebooting it shows that it is being charged but as soon as complete all the startup process it would again stop charging.
(plus i also sometimes get a faint line on display running horizontally at the center of my display. It faints further on use.)
Any solution please. Thank You

Random instability??

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.

Droid Turbo 2 Sudden Shutdown + Boot loop

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.

Boot Loop/charging problem

I have a stock G4, which I replaced the screen on a few months ago.
Every few days, it randomly powers off and then wont turn back on. When I connect a charger, I get a bootloop with the splash screen appearing/reboot cycling.
Fastboot works (although I only tried this with a charger, not a PC attached).
Eventually the phone will seem to reboot correctly (after charging for a while, rebooting into fastboot)
One thing that does seem to work is 5 minutes in the freezer... After a restart this shows that the last crash occurred with 92% battery. - but then it keeps powering off with no warning, and fastboot indicates low battery...
I'm guessing either hardware/power management issues, or battery problems - the phone is 2-3 years old...
Edit : Further messing about suggests the battery is completely hosed...

S7 Edge gets into rebooting loop then just went off with no signs of live

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...
