Hi Sony team

[Chetra]

I've used Sony Experia for around 2 years without any problem, I recently got some problem with battery dropped down without used it. And when it goes to 45% of battery I note that just every second it drop down fast to 0% just only 3 minutes without used it. Please help me out.

If PCC doesn't solve the issue then you must contact your local Xperia Care

Keep us updated. 

[Chetra]

Ok, but PCC is just for repair and update, right? I think I should update my phone and will my battery is back to normal?

@Chetra

If its a software issue it might, but it seems to be a hardware issue. 

[Chetra]

If hardware issue, so what should I do?

[Chetra]

I haven't found that issue on google or youtube either. Only mine I think
