iPhone running iOS 18.1 has a new feature called 'inactivity reboot' which restarts the device after four days of inactivity to make it harder to hack.
An iPhone that hasn't been unlocked since the last reboot is difficult to hack, while one that has been unlocked is easier to crack.
This new feature affects police and repressive regimes trying to access seized iPhone units or target activists and journalists.
Apple's commitment to privacy and security is evident in its continuous efforts to protect user data and embed privacy protections in their products.
