This is a most excellent place for technology news and articles.
Its an aosp feature i believe, but its disabled on many phones. Graphene and calyx have it. With calyx its default off, but you can set it between 1 and 72 hours. Very handy feature.
Graphene is set to reboot after six hours of inactivity, ensuring that it reboots every night after I've gone to bed.
