Signs of Battery failure?

[Thasaltinecracka]

Hey there. So I have an issue with Keeping the phone on. I guess I should break it down into charging vs pure Battery as I can sometimes do a poor job of explaining things properly. Note: the screen glue is worn off so I can easily remove the screen with my fingers, and most of the time w/case on one of the bottom corners will be sticking up.

Turning on when charging: Turns on like normal, but 8/10x phone will instantly turn off as soon as it reaches the lock screen. But since it's plugged in, instantly shows battery life screen w/no indication (supposedly) of battery charge loss.

After unplugging when turned on: Will shut off w/o warning at various battery levels. Started off only below 20%, now could have as high as 85% when it shuts off. When you plug it in to charge it shows no signs of a low battery

Turning on when using Pure Battery: Only gets to Galaxy logo then turns off.

Bring the phone to a good repair shop and pay them to fix what you broke by lifting the screen off. You may have pulled a wire out or a wire that got tightened may have broken something else.

It's no use guessing what the problem is, when you could have broken anything by just pulling the screen off the frame.
