How to Factory Reset My iPhone

Performing a factory reset on an iPhone can solve technical errors you may encounter during the device's lifespan, such as having the phone unexpectedly power off or lock up. Executing a factory reset restores the iPhone's data to a mirror image of the first day you removed it from its package and turned it on.
