How to Replace iPhone battery?
To start, you need to determine if you need a new battery or if you just need to charge it more. To do this, turn off your phone and look at the battery icon in the top right corner of the screen. If the battery is yellow or red, it needs to be charged. If it’s white, your phone probably only needs a new battery.
Once you know whether or not you need a new battery, remove the old one by gently pressing on one end and then pulling outwards. Make sure to keep the plastic cover that was attached to the battery when you bought your phone.
