Downgrade iOS 16 to iOS 15

If you recently updated your iPhone to iOS 16 and have decided it’s not for you, perhaps due to some incompatibility or battery issue or otherwise, you’ll be excited to know you can downgrade from iOS 16 and revert back to iOS 15.

This article will cover an easy approach to downgrading, and you’ll be removing iOS 16 from your iPhone in no time at all.

Prerequisites to downgrading iOS 16

  • Download iOS 15.7 IPSW here that matches your iPhone model
  • A Mac or Windows PC with Finder or iTunes
  • A USB Lightning cable to connect iPhone to the computer
  • An internet connection
  • A full backup of your iPhone to iCloud or a computer, in the event something goes wrong so you can get your data back

Assuming you meet those requirements, you are ready to remove iOS 16 from your iPhone and revert back to iOS 15.

How to Downgrade iOS 16 on iPhone Back to iOS 15

Be sure to backup your iPhone before beginning this process. If you fail to backup, you could have permanent data loss and lose everything on your device.

  1. Open Finder on the Mac, or iTunes on a Windows PC, and select your iPhone from the sidebar menu
  2. Go to the “Summary” section, then hold the OPTION key on a Mac, or SHIFT key on a PC, and click on the “Restore” button
  3. Navigate to the iOS 15 IPSW file that matches your iPhone model that you already downloaded
  4. Choose “Restore”

After the downgrade has complete, your iPhone will boot back into iOS 15.7, assuming the whole process went well anyway.

This approach attempts to downgrade without erasing the iPhone, but it’s critical to have a backup made beforehand in the event that something goes wrong, or that you choose the wrong option, you can still restore your data.

Remember, downgrading is only possible for as long as iOS 15.7 firmware (or other iOS 15 releases) are being digitally signed by Apple, so don’t expect to be able to do this forever.

Did you decide to downgrade iOS 16 and revert back to iOS 15? If so, why? How did the process work out for you? Let us know your experiences in the comments.

    I have fond memories of my first iPhone, the 3GS. The first generation of this model did not have a locked bootloader so could be upgraded and downgraded at will. Today, if you are not satisfied with an upgrade and you’re not quick, downgrading is not possible. iOS 15.7 and 16 being available at the same time is an exception. When Apple have released 16.1 and 15.7 is no longer available, you can not upgrade to this level ‘just to test it’ if you want to be able to downgrade again to a level known to work well for you and your apps.
