This is a most excellent place for technology news and articles.
I think graphene does this by default now? Like if you don't unlock it for 24 hours it'll reboot.
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.
18 hours by default.
