Q1. Should I skip iOS 15.7 and update to iOS 16?

It is generally not recommended to skip over an incremental update like iOS 15.7 when a major new iOS version is available. iOS 15.7 contains critical bug fixes, security patches, and refinements that help optimize performance. Updating to iOS 16 right away can introduce new bugs and issues that are still being addressed.

Installing iOS 15.7 first allows you to benefit from the fixes and stability improvements in the incremental update. This then provides the best foundation before moving on to iOS 16.

Q2. Can I go back to iOS 15.7 from iOS 16?

Yes, you can downgrade and revert to iOS 15.7 after updating to iOS 16 if needed. To do this, you will need a valid device backup from before you installed iOS 16. Connect your iPhone to a computer and open iTunes (Windows) or Finder (Mac). Then enter recovery mode and restore from your earlier iOS 15 backup file.

This will wipe your device and revert it back to the saved state on iOS 15.7. Make sure your backup is complete before updating to iOS 16 in case you need to restore back to 15.7.
