iOS 4.1 & 4.0 on the 4s
My battery drains to 0 in a day even when not used sitting in standby. I have tried resetting to factory settings & resetting to new phone. I have replaced the battery 2X. To trouble;e shoot the issue I tried to see if the battery drains when the phone is turned off. I cannot turn the phone off & keep it off. When I turn it off it turns
back on in a few minutes automatically.
My phone has become useless!!!
iPhone 4S, iOS 8.4.1
