Restore all content to iPhone from a backup
You can restore content, settings, and apps from a backup to a new or newly erased iPhone.
Important: To restore your iPhone, you must have a backup to restore from. See Back up iPhone.
Restore iPhone from an iCloud backup
Turn on your iPhone.
The Hello screen should appear. If you already set up your device, you need to erase all of its content before you can use these steps to restore from your backup.
Do one of the following:
Tap Set Up Manually, tap Restore from iCloud Backup, then follow the onscreen instructions.
If you have another iPhone, iPad, or iPod touch with iOS 11, iPadOS 13, or later, you can use Quick Start to automatically set up your new device. Bring the two devices close together, then follow the onscreen instructions to securely copy many of your settings, preferences, and iCloud Keychain. You can then restore the rest of your data and content to your new device from your iCloud backup.
Or, if both devices have iOS 12.4, iPadOS 13, or later, you can transfer all your data wirelessly from your previous device to your new one. Keep your devices near each other and plugged into power until the migration process is complete.
You’re asked for your Apple Account. If you’ve forgotten your Apple Account, go to iforgot.apple.com.
