The latest version of iOS introduces a notable security feature designed to enhance device safety. When a device is unlocked and remains in use for 72 consecutive hours, the system will automatically initiate a reboot. This means that even after unlocking the phone, it will eventually restart and lock itself again after the specified time period. This feature aims to protect user data and prevent unauthorized access, contributing to overall device security. Users are encouraged to be aware of this functionality as it may affect their device usage and accessibility, particularly during prolonged periods of activity.
