Apple added a feature called "inactivity reboot" in iOS 18.1. This is implemented in keybagd and the AppleSEPKeyStore kernel extension. It seems to have nothing to do with phone/wireless network state. Keystore is used when unlocking the device. So if you don't unlock your iPhone for a while... it will reboot!

In the news: "Police Freak Out at iPhones Mysteriously Rebooting Themselves, Locking Cops Out"

iOS version diffs to see yourself:

@jiska@chaos.social hmm I saw another article dismissing the 404 media one, citing an iPhone reboot bug in iOS 18.0 fixed in ios 18.1 …

Based on these I suspect that it already got implemented in ios 18, though with a bug (random reboots) that was fixed in ios 18.1
Edit: it might also be something unrelated…

@jiska one wonders whether this is an intentional security feature or just a workaround for some hard to fix bug.

@jiska Hell yeah! This is not only great for security, but for the general user who rarely/never intentionally shuts down or reboots their phone. Helps prevent resource usage creep (which I don't often experience on iOS anyway)

@jiska @cstross Is this also in iPadOS? I have mine on a stand next to my Mac’s monitor (which it is also connected to via a USB hub), but it is my least-used device, and it mysteriously rebooted itself last night.

@jiska Locking pigs out is a happy side effect that is good for everyone.

@jiska at least police have effectively confirmed for us that they keep seized phones powered up in a Faraday cage

@jiska interesting. My Android just got a new update with this similar feature:

"Offline Device Lock automatically locks your screen if a thief tries to keep your phone disconnected from the Internet for an extended period of time."

It's not a reboot, but also inactivity triggered.
