The “Quick Start” feature on iPhones allows you to move to the new device smoothly without the need for a computer. The transferred data includes: photos, messages, applications, and settings. There are many transportation options according to need:
Fast wireless transfer: Place the two phones close together, scan the mobile code with the old camera, then choose direct transfer or restore the iCloud copy.
Wired transfer: To solve problems of a weak Wi-Fi network or large files, using a suitable cable (with modern models supporting high speeds of up to 10 Gigabit).
Backup: via iCloud, Mac, or Windows computer if the old phone is delivered within the exchange program.
It is recommended to update the iOS system on both devices and check the storage space before starting to ensure that the process is successful without obstacles.
