Xbox Series X Quick Resume Works Even After A Console Reboot
A loss of power will not wipe your fast resume instances on either the Xbox Series X and Series S.
Quick Resume won’t just work while your Series X/S is in or on standby. Instead, game conditions will also be kept during a complete console cold boot, which contains a full reduction of power to the console. You may still presumably lose progress if the console loses power unexpectedly, like a power outage such as. But if you’re planning to close down your Series X/S for an upgrade or if you would like to move your console, you can be certain that your matches will be prepared when you boot up again.
It is a feature that will let you zip between paused matches in a sense only the new internal SSD can afford, but it can save your progress after a console reboot.
