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.

    could be a simple hot spot cell backup, like for reporting network outage, remoting in to certain devices, etc. essentially a secondary ISP to report on main isp and troubleshoot. especially if you have smart devices you could reboot remotely.

      An iPhone is not going to be that. This isn’t phones in general doing this, just iPhones.

      There are also far more efficient devices for that. More cost effective and more energy efficient.

      I understand wanting to reuse old devices for something, but there’s a limit to what is power efficient as well.

          When it comes to iPhones, it’s not a shouldn’t, it’s a can’t.

          The way iOS limits background process means you can’t. I develop for iOS apps for a living.

          There’s still you should never under any circumstances allow unsupported devices to be exposed to the internet or any way. Because that’s how we get bot nets causing DDOS attacks.
