Why does my tablet charge and turn on but then off immediately?

By the way I’m sorry if there’s a place already asking this, I’m new to this sote and didn’t see one with this problem.

So this has been going on for a while and I’ve got it to work a few times in the past by getting it to stay off somehow, but I don’t remember how I had done that. Plus for some reason it’s been losing power pretty fast.

The problem is that when I plug my tablet up to charge it will charge but tries to immediately turn on at just enough power to turn on, it goes through it’s whole turning on thing with logos, but once it gets to the password screen it immediately pops up a message saying it’s powerting off because the battery is too low. Considering all that time I have it charging I would assume that would help but no.

I’m pretty sure it has somethings to do with the screen using extra something like a lot of places say but I’m stilll not sure what to do.

Even when I turned it off with power it sometimes turned on like that with none.
