How to Downgrade from iOS 16 to iOS 15

This is how you bring your iPhone back to iOS 15 from iOS 16.

If you run into iOS 16 problems on your iPhone and you think moving your iPhone back to the previous version of iOS could help, this guide will help you downgrade.

You can only go back to iOS 15.7.1 or iOS 15.7. You can’t go back any further than that. The path back to older versions of iOS 15 is closed and it won’t re-open.

Once you downgrade, you can only restore a backup that you made on iOS 15.7.1 or iOS 15.7 so keep that in mind in case you need to restore a backup.

Most users will have a recent backup, but you may lose some items if you aren’t regularly backing up your photos and messages to iCloud.

While this isn’t officially supported, it is easy to do and you won’t lose any customer support or mess with your iPhone’s warranty.

How to Downgrade from iOS 16 to iOS 15

Here’s what you need to do to go back to iOS 15 on your iPhone. While you are downgrading you cannot use your phone so you will need to open this on your computer or another device.
