iPhone 5s phone - Battery die fast and power off auto and ask for to connect charger
I have iPhone 5s phone, had battery issue. Initially I thought it was with battery but it's not. i replaced with new one but still the same issue. I charged to 100% but when I leave it for night the phone would be dead in the morning and asked to connect charger. The battery is dead without even using it. Sometime I feels phone is really hot when it's being charged. Another noticeable thing is; when we left shutting down the phone battery won't go down, it's good but that doesn't make sense right, we can left switching off the phone. Please suggest, anybody?
iPhone 5s, iOS 9.0.1
