Question: Iphone 6s Battery suddenly draining
Why is my 2 year old iphone 6s battery suddenly draining? Just recently my phone battery has started draining. I kept it on standby overnight starting at 100% and in the morning it was at 1%. The usage was only at 30 min and the standby at 7+ hours so what is draining my battery?
iPhone 6s, iOS 11.4
