There’s nothing listed on the Apple Support site about an automatic restart feature when there are no cellular networks nearby. I’m guessing they left the phone connected to a charger long enough to install a previously downloaded update.

When automatic updates are enabled, iPhone will coalesce the software update download with other download activity. The package will remain downloaded and install once the iPhone is connected to power, and remains powered on and locked for an extended period of time. The install initiates a reboot.

This is a better article with a link to the code. It has nothing to do with a software update (beyond being an unlisted feature of 18.1) and is based on an inactivity timer.

That’s great! I couldn’t find any mention of it on support.apple.com or on the iOS 18.1 details page.
