Doesn't seem like the sleep/quick resume option on Xbox Series X serves much purpose - it boots from full shutdown faster than I remember a PS1 booting.
@waded if I’m not mistaken it allows you to remotely wake it up from a different device to do remote play.
@gpowerf Yeah, the bullet in the settings making the case for it is "Needed for remote wake and fast boot" - "fast boot" is certainly quite fast, but not as notable as it used to be. Remote wake/install is good stuff but it's rare for me. (It doesn't mention updates at all, which is kind of odd.)
