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.
Things You'll Need
- USB cable
Connect the phone to your computer using the iPhone's USB cable. iTunes loads automatically.
Click your iPhone in iTunes' "Source" list on the left.
Click "Summary," positioned among the tabs.
Click "Restore" to begin setting up the factory reset. iTunes prompts you to back up your iPhone's data.
Choose "Back up" if you want to allow iTunes to record a copy of all your iTunes data, or choose "Don't back up." A new prompt appears asking for final confirmation on the restoration.
Tips & Warnings
- If you choose to back up the iPhone, you can restore it back after you reset it to factory settings.
- Every time you plug your iPhone into iTunes and sync the device, iTunes backs up your iPhone's data.
