If you lose your iPhone or buy an upgrade, you could reasonably expect to be up and running after an hour, presuming you backed up your prior model. Your Apple stuff all comes over, sure, but most of your third-party apps will still be signed in.

Interesting, I didn’t know Iphones did this. Will reduce the friction even more when switching phones.

One thing to note. They still exist on your phone. But, are uninstalled for the primary user.

Not buying a carrier locked device would be a start.
