Turn on Sleep for Faster Wakeup (Though regular settings are already good)

If you’ve ever been annoyed at how long it takes your Xbox to start up, that’s because, by default, the Series X supports its “Shutdown (energy saving)” compared to what most people assume is a default sleep mode. This default console shutoff still supports automatic updates, unlike the PlayStation 5 or Nintendo Switch. However, it’s also slightly slower to start up, and if that’s really a concern, you can change it under settings, then General, then Power options.
The Xbox makes it clear that changing this setting increases power usage when powered down by 10 to 15W, so there’s not much reason to change it unless you want to start the Xbox remotely.
