iPhone added this feature very recently (just a few months ago, it basically just randomly restarts the phone if it is unused and not connected to a network for over 24-48 hours - phones connected to a network can be erased via iCloud). Android doesn’t have it at all.
There is a shortcut, however, on iOS to secretly put an iPhone into BFU mode - quick tapping the power button 5 times will lock the phone and erase the aforementioned in-memory keys so that it needs a password to unlock.
(EDIT: it does not actually put the iPhone into BFU mode. It just disables biometrics.)
