Why does my tablet shut down suddenly after 10 minutes of use?

[AC Question]

2 weeks ago my tablet got a bad hit in a car accident , after the car accident the battery life time decreased from 4 hours to 1 then after a couple of days the battery only was able to survive for 30 minutes from a full charge because the battery was draining so fast , then the tablet started to shut down suddenly after 10 minutes of using it , i start using it at 100% and when it reaches 70% to 85% it shuts down it self and when i turn it on the battery goes down to 21% , i changed the battery but the problem is still there , so what causes that and what should i do?

That may need diagnosis by a repairer.

Hardware damage. Plug in your tablet and back up the data, then replace it.
