On Thursday 404 Media reported that police were freaking out about mysteriously rebooting iPhones. Now multiple experts have found that Apple introduced code that reboots locked phones after a period of time.

Apple quietly introduced code into iOS 18.1 which reboots the device if it has not been unlocked for a period of time, reverting it to a state which improves the security of iPhones overall and is making it harder for police to break into the devices, according to multiple iPhone security experts.

On Thursday, 404 Media reported that law enforcement officials were freaking out that iPhones which had been stored for examination were mysteriously rebooting themselves. At the time the cause was unclear, with the officials only able to speculate why they were being locked out of the devices. Now a day later, the potential reason why is coming into view.

“Apple indeed added a feature called ‘inactivity reboot’ in iOS 18.1.,” Dr.-Ing. Jiska Classen, a research group leader at the Hasso Plattner Institute, tweeted after 404 Media published on Thursday along with screenshots that they presented as the relevant pieces of code.

        This is good but it isn’t quite the same thing. I want my phone to auto restart if I haven’t unlocked in for 12 hours.

      Looks like the big difference is that this is on by default, it appears to get enabled when cops turn off internet access to prevent access to FindMy and remote lockdowns.

        There’s also a feature to disable the biometrics for unlocking in general but to stay active to unlock apps (like bank apps or password managers). I like this because no matter what you can’t unlock my phone without the pin but I still get the convenience of using it for my app security
