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 rebooting for a different reason. That auto reboot just kind assumes that the software on your phone sucks and it needs to reboot to stay running fast.
Graphene and now iOS auto reboot for security/privacy reasons.
The end result is the same though. First phone unlock is the one a bad actor can’t get through.
It’s not the same.
On an iPhone it’ll reboot after X hours of no use. That means it could go months without rebooting and the day after it’s in police hands it reboots.
The feature you’re talking about would need to be set to reboot every day at a specific time. Now you personally have to deal with that. Also until you unlock the phone as well there could be reduced functionality making it annoying.
Very different.
Not that hard to deal with honestly. Rebooting at night which I’m sleeping does not reduces any functionality, cuz I’m not using it. If someone needs to find me during the night he better call me cuz I won’t wake up by notification which is also suppressed by DND. Yeah it is not design for security but a solution better than none.
Furthermore, rebooting the device periodically is good for security, especially for non-persistent fileless malware.
