How to Factory Reset an iPhone

Are you planning to sell or give away your iPhone?

If you're selling your iPhone or sending it in for repairs, you don't want to leave your personal data and photos where prying eyes can see them. You can safeguard your data by factory resetting your iPhone.

When you factory reset an iPhone, the phone returns to the condition it was in when it left the factory. There will be no music, apps, or other data on it; just the iOS and the pre-loaded apps. You can also factory reset an iPhone to fix problems with jailbreaks and other tricky problems. Here's everything you need to know about performing a factory rest on your iPhone.

The instructions in this article apply to iOS 12 and up, but also work with older versions of iOS.

Back Up Your Data Before Starting Factory Resetting iPhone

The first step any time you factory reset your iPhone is to back up the data on the iPhone. Keeping a copy of your most data lets you can restore it on the phone later so you don't lose anything important.

There are three options to back up data: using iTunes, the Finder, and iCloud.

  • To back up to iTunes, sync the phone to your computer, then click the Back up button on the main iPhone page.
  • To back up on a Mac running macOS Catalina (10.15) or newer, plug the iPhone into the computer, open a Finder window, select the iPhone in the left-hand Devices menu, and back Back Up.
  • To back up to iCloud, go to Settings > [your name] (skip this step on earlier versions of the iOS) > iCloud > iCloud Backup, then start a backup.

Disable iCloud & Find My iPhone

The next step in factory resetting your iPhone is to disable iCloud and Find My iPhone. In iOS 7 and up, a security feature called Activation Lock requires you to enter the Apple ID used to set up the phone if you want to reset it. This feature has reduced iPhone thefts since it makes a stolen iPhone hard to use. But if you don't disable Activation Lock, the next person who gets your iPhone—either a buyer or repair person—won't be able to use it.

Activation Lock is disabled when you turn off iCloud/Find My iPhone. Here's what to do:

  1. Go to Settings.

  2. Tap your name (skip this step on earlier versions of the iOS).

  3. Tap iCloud, then tap Find My iPhone. (In iOS 13 and up, skip iCloud and just tap Find My.)
