Note Keeps Switching Off, Running Out of Ideas

Hi - a few days ago my SGN turned off when I was playing GTA so I plugged it in and kept playing it. I noticed that battery levels were reported as ~50% before the first switch offs then 14% when I switched it on again. Then it happened again a few times then it turned off when I switched on WiFI just after booting. Basically over the last day or so it started turning off during the boot animation and wouldn't even boot most of the time.
So after reading a few threads here I tried flashing to stock GB then stock JB - it pretty reliably boots to the language choice screen then switches off on the next screen which turns on WiFi as it happens, not sure if this is relevant but wierdly when it was switching off in GTA it seemed to be at the same spot each time in the game. The thread which I got method from said to use Kies but I could only use Odin to flash JB since it turned off before it finished:\
Also discovered that whilst it will switch off on the CWM screen even it appears to be fine when it's in download mode.
So looking at another method to fix this here I put Note into download mode and ran down the battery, left it for 10 minutes, turned it on again until it died again, left it for an hour and fully charged it off wall outlet. Basically this appeared to do nothing for the situation.
So I don't know what to do next - any suggestions? I'm pretty sure it's some issue with the battery but I don't know what: it can sit for hours and hours in download mode to run flat without switching off but will switch off during CWM recovery and just after booting stock JB ATM.
I'm thinking I'll grab a cheapo battery off Ebay and see what happens to start with. Can anyone suggest anything else?

I'm sure You can use the phone while keeping it on constant charge. How old is your battery? This is surely a battery problem and i suggest you to buy the original samsung battery. And once you change your battery, do not overcharge the battery by keeping it for charging overnight and such ways.

It was restarting when it's plugged in to charger but I just switched it on and got past all the OS setup steps so fingers crossed. Turned off as soon as I uplugged the charger though.
Battery is original and quite old, got the device late 2011. Thanks for the advice.

Replace the battery asap with original one as if the battery is overused, it may swell up and damage the back cover. Do hit thanks if i helped

Phone goes into reboot loop when unplugged from AC

Hey guys I am new to this forum.
My S3 mini been running stock android 4.1.2 for over a year now with no issues. Yesterday the phone just reboots by itself and the battery went from 60% to 14% in a second. Then the phone got stuck in a reboot loop, I had to take out the battery to make it stop rebooting every second. I tried charging the phone all night, for 8 hours, got 10 minutes of usage out of it before it started rebooting again and the battery inexplicably jumped from 90% to 14% ! The phone is only usable when plugged to the AC, basically not a mobile phone anymore.
Did a factory reset, Thought it might help, it didn't. The phone works fine when plugged to the AC, it only starts rebooting a few minutes after I unplug it.
Help please, should I get a new battery?

Update:
After replacing the original battery with a new one the phone went back to normal function. Also , when removing the old battery I noticed it's a little swollen.
Thanks everyone for the help.

0% battery after crashes

So I've had this phone for about a year now, the moment I got it I unlocked the bootloader, rooted it and flashed cyanfox (cm11 fork) onto it.
It's been serving me great ever since, no problems whatsoever with it.
But as of a few days back I found it with a black screen, unresponsive. I connected the charger and it light up the green led solid, tries to boot but can't get past the boot loader message
This continues in an almost endless loop until getting to a 'battery 1%' screen with it showing the battery. After that I'm able to boot it up without problem
I first thought that was the end of it.. I finally got it too boot all seemed fine, battery showed 3% at start up bit voltage was suggesting it was 100%. It flashed to 100% later.
Good, no problem until then. But when leaving it over night to charge and disconnecting it from the charger this morning it turned off again. And now it's back in the bootloop when on charger :crying:
also important to mention is that when it crashes and gets into the bootloop on charger(0% battery and all) it was at 50-100% before the crash.
If anyone has any ideas what might be the cause I'd be very thankful
Main problem(s):
-random crashes instantly rendering battery % as 0 while there is still charge
-getting atrix hd to turn on at <1% battery
Some maybe useful information:
-it does say 'battery OK' in fastboot while connected to the wallcharger
-after I get it to boot it will run just fine on battery and charge as normal, but will crash/brick again after some time
-I can get into boot selection screen and fastboot, but only on wallcharger
-I cannot get to fastboot when connected to use, pc doesn't see the phone
-It won't boot past the bootloader('Motorola logo' for you on not unlocked bootloaders) no matter the boot selection(recovery, bp tools etc)
-This is a second hand model already in use by me (the second owner) for over a year now
-no custom kernel, only rom, cyanfox 4.4.2 (cm11 based)
-the few times it got past the bootloop and I was able to boot was on my aftermarket charger (stock charger will make the green led light up but no proof of being able to get past bootloop over time on it)

I've had dead batteries before.. and since It looked good last time I got it on (it won't go on at all now) I was skeptic about the battery being dead. But a quick test of the multimeter gives me <1v :crying:
I know batteries can be drained pretty bad.. but this just seems a bit extreme.. I'll try to get it to boot for a while.
Thanks in advance for any helpful solutions or ideas on the matter
EDIT: Got it on again last night, turned off this morning when pulling out the charger, was at 100%. Checked battery and again read around 1V.
blaming the battery, ordered a new one just in case, should be here in a month or so. Still open for suggestions on the matter

Did you fix it somehow in the end?
My Atrix HD freezes after several minutes(sometimes even on wall charger). Bought new battery, tried to reset everything: usb storage, cash, system, factory reset. Went back to ROM I was using before(stable) but didn't help.

It ended up being the battery, all problems were gone after I changed the battery.
Which in the end wasn't so bad because I'd been wanting to upgrade my eb20 to an eb40
No Idea to what it could be in your case.
Everything working appart from that? no battery hickups or things not working properly?

"0% battery after crashes" that is what was happening in the begging, so I thought it is the battery. I changed it to UB40
but everything's got worse. With the new battery I have crashes even when the battery is almost full.(but not always, for example I can play movie from youtube normally, but when I try to send sms or something else it crashes ).
Hard to believe that there is something with the new battery(I have it just one week+It took a month to ship from ebay).
I tried to flash another ROM, but still have freezes.
Last thing sometimes battery charges normally but then suddenly jumps to ~100%. Now I try to flash Stock ROM, but eventually soft bricked the phone. (+had "battery low" in fastboot, while charging animation was saying 100%)
Where did you buy EB40?

It turned out that EB40 battery was bad, after replacing it with another one everything work

Xperia Z battery problem

Hi guys my Xperia Z1 was charged to 100% after some use normally went down to 93% next second i pulled the phone out of the pocket it was turned off tried to turn it on got it to vibrate once but nothing showed up on display tried once again few minutzes later it booted up but just went off on bootloader. I came hame and put it on charger phone turned on showing like 50% battery drained it to zero started charging to 100 on 60-70% on charging suddenly went up to 100%
i used phone for 2 days with random reboots and after switching it on showing different percent of battery remaining, today it wont work without charger after i disconect charger phone shuts down. Could anyone tell me if this is problem with battery or its faulty motherboard maybe? thanks
ps. i need fast answer because im about to buy a battery

Tried to boot phone into safe mode and see how it reacts? Also do you use Stamina mode or any other service that changes or reads system properties?

whats the point of booting in safe mode if battery percent is going crazy even when phone is charging wile its shutdown

You have classic symptoms of a dying battery. Replace it and the problems will go away... If you did a search, you would find exactly the same symptoms described by others and the same solution. Your battery can't hold power due to a deterioration of cells.

No as the phone is rooted it will be of no use

Try to make your phones battery empty as much as possible....my note 8 was doing the same thing...i waited for its battery to go to 0%..but even after it turns off itself... whenever i press the power button it turns on again and then turn off after the boot up..which means that it's battery is still not fully 0%...to make the phone complete dead..i went to boot locker and Waited for some time...after some time it was automatically ded(because in bootlocker the phone screen is on constantly)....then i recharged it to full 100% and now it's good as new.

Calibrating the battery like that sometimes does the trick. What you should keep in mind is that deep discharges wear down lithium-ion batteries, which can prove troublesome in phones with a non-swappable battery.
