> law enforcement officers and forensic experts were concerned that some iPhones were rebooting themselves under mysterious circumstances, which made it harder for them to get access to the devices and extract data.

> iOS 18 comes with improved anti-theft measures. Three days w/o unlock, the iPhone will reboot, preventing thieves from getting your data.

It's poetic, isn't it?

I'd like to be able to specify much shorter times than 3 days, I could have my phone reboot every night while sleeping if possible

On iPhone, you can use the Shortcuts app to do this. Create a new shortcut with the Restart action and save it. Then go to the Automations tab, set the schedule, and select your new shortcut. Make sure it's set to Run immediately.

Woah, I never cease to be surprised by the unexpected kinds of things that Shortcuts allows (given all the obvious ones it does not). Thank you!

Out of curiosity (and because I'm not going to try that for tomorrow morning) – does that kill my alarms, or does iOS schedule/store these somewhere accessible before first unlock?

iOS alarms continue to work after overnight upgrades which involve a reboot, and also work when you plug in a dead phone before bed, so they’ve apparently figured this out.

It’s actually pretty powerful and you can have automation tigger based on all sorts of things.

I travel a lot so have it turn on specific data SIMs when GPS detects I’m in that country.

AFAIK there's (private?) API surface to request a container that isn't encrypted to your PIN specifically for the lock screen to work.
