pls help: battery problem

[AC Question]

I got a new samsung galaxy tab e. It worked fine, but then ithe percentage went up during charging like 10 percent right away. After, it looked fine, just a little faster draining. Then in a few days, it went down about 10 percent. Now it is draining, but is charging very quick but draining also. What do i do?

It may be a bad battery.
