The iOS 13.4 beta 3 released tonight highlights a new recovery feature called "OS Recovery". Its particularity is to allow a user to restore his iPhone / iPad from another iPhone / iPad, without going through the Mac.
9to5Mac, our colleagues behind this discovery in iOS 13.4 beta 3, explains that this restoration could be done as well over Wi-Fi as using a cable. In addition, it would also be possible to restore from Apple's servers, in the same way as with a Mac.
The advantage of the OS Recovery function would be to be able to function even if the iPhone / iPad is no longer able to function, unlike iCloud backups.
This new restore option is a great idea, although at the moment we can't test it. It’s likely to be officially released by iOS 14. The first beta is expected in June for developers and this fall for the public version.
If Apple really comes to offer this function then we can imagine that one day the iPhone will be devoid of connector. Several rumors have indeed spoken of this hypothesis: an iPhone without Lightning port, or USB-C.
