Battery Problem in A30

[SanRay2001]

I found a prob in my battery that like one day when the charge went to 19% suddenly it started rapidly reducing to 10% then 5% then 0% within a minute.

And also one other thing I charged my phone till 80% then the auto restart took place as scheduled in night and after that I see is it is charged 100% 

Is this a serious problem?? @interchupipi please respond to this. I need a solution from you people🙏🏼🙏🏼🙏🏼
