"The idea is to minimize the window of opportunity for attackers and disrupt existing compromises by resetting all protection systems on the device more frequently than a user would. GrapheneOS' auto-reboot system resets the device every 72 hours but as the OS maker comments, this is too long a period and they plan to reduce it. ... The auto-reboot timer since the last unlock (not since last boot) has now been shortened to 18 hours (from 72 hours)." Another reminder of the depth of the mess that is modern consumer device security.
