Prepare your data for a new iPhone
Use iCloud via iOS 15 to create a temporary back up of your iPhone’s apps and data
You may be moving to a new iPhone but there’s a very good chance that you’ll want to make use of your apps, data and settings from your old device. With iOS 15, it is now even easier to make the transfer using a new feature called Prepare for New iPhone, which gives you 21 days to make the switch.
