Second Hand “Brand new battery fitted in store, 100% Battery Health. The screen, rear glass and housing are all in very good condition with very little signs of use and with 64gb of storage.”
** As apple pair certain components to the phone motherboard (screen, battery, camera) replacing these components will display a message on screen to show that the phone cannot verify the parts are original. This is completely normal and does not affect the phone performance in any way. Replacing the battery with a non genuine one will disable the battery health reading feature of the iPhone but the battery will work as normal.
