Battery problem or Kernel problem? - ZTE Axon 7 Questions & Answers

I have a problem with the battery, it only points 1% and it does not load, I left the Oreo stock, for this ROM[Aroma SL!M DF!NR 7.1.1 MF5.0 - by raystef66] and it persists, the problem started after I put it to load and it automatically turns on and stops the boot on the screen. password (the one required to turn on the phone completely) charged there, I took the charger (which is original along with the cable) I used a few minutes, I locked the screen when at 88% charge, it turned off and when I called again it was just boot screen claiming low battery.
I turned on in the TWRP EXCLUSIVE by NFound and kept the screen on for hours and did not turn off, the battery reading was not shown, what do you think it could be?

Normal Defy Battery Behaviour?

I recently acquired a Defy and immediately installed CM11 on it. My main phone is a Nexus 4 and one of its best features is that even if the battery is completely drained, if plugged into the wall charger it will immediately boot up. The iPhone I had before would show a low battery screen until it reached around 10%, at which point it would finally boot.
It seems that when the Defy battery drops below 15-20%, it will not boot at all - pressing the power button does nothing. I plug it into the mains and the usual white light does not show. It still seems to charge and I can eventually boot into recovery to see that power has reached around 20%. At this point if I disconnect from the charger the phone usually boots up. I haven't had it long enough to troubleshoot extensively but I think that while plugged into the wall it is less likely to boot successfully. An unsuccessful boot starts with the Motorola logo, then the screen goes black and the buttons flash once, at which point the boot fails.
Is this at all similar to the experiences of anyone else, or could it be a battery / firmware problem?
Thanks
Have you tried to remove battery, insert it again and then try to boot?
I had the same problem once, I'm on cm10.2. Maybe we should replace the battery, I always charge it before reaches 30%

Sudden shutdown,Power on only when plugged to Charger(80% battery). Powr button Stuck

Suddenly one day,When I switched on Mobile data, My display went and not responding even after trying all the key combination(Power button+volume Key,etc). But when I plugged to charger, suddenly the battery display came and later booted normally. Charge was showing 80%. After that frequently it showed this issue. I thought it was battery calibration issue and drained battery and make it 100% 4-5 times. Then I formatted/factory reset it once. But still the problem is there. If I connected turbo charger,To become 2% it was taking more than 30 minute, That too when I unplugged and plugged again only it was increasing to 3%.
Also some times when we press power button, display will not go off. We need to click 2-3 times to make display off. Also when press to unlock the phone,it will not come other than we press suddenly with some pressure.
Recently I Changed display of my mobile due to a issue like display was flickering with we move and only one fourth of display was visible on screen. Please help me in this.
seems like a water/fog or mechanical damage

Help! Phone doesn't turn on

So I've had my Moto X Pure (XT1575) for almost two years now, and it's been through hell and back with me. A few months ago, I replaced the screen because of the hot spots the screen had since I've bought it, at the same time, I replaced the battery, the frame and installed a wooden back cover. Yesterday, while I was using it, the phone died and started trying to boot itself back up. I thought it was a sudden turn off, like when you have 30% and it dies because the battery is old. So I let it in the charger for a few minutes just so I could turn it on; but it didn't, it turned on for a split second, showing the bootloader unlocked screen and dying instantly. Luckily I managed to boot it once, and what was weird is that the battery showed 50%+ charge and was charging normally. I went to sleep and let it charge overnight, now it flashes the white led as if the battery level was too low to turn on. I suspect it's a bad battery, but maybe it could be something else. Any help is appreciated.
UPDATE: I've tried to boot the phone again but it doesn't want to do it, it just flashes the bootloader unlocked screen then dies, it's like a bootloop but weirder. Tried to get to the fastboot menu and it lets me, it says "battery is low" in the battery status, which is weird, since it said "battery OK" yesterday.
NVM, I opened the phone and disconnected the battery and put it back on and the problems fixed itself

Droid Turbo 2 Strange Boot Loop

Alright,
I replaced my battery today (the battery I replaced drained very quickly) and that is when all of my problems started.
Droid Turbo 2 | Verizon | Completely Stock | Latest Software
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?

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...
