"Although Microsoft reduced the power drain from its 'instant-on' mode from 18 watts to 12.5 watts, the mode is still the default when it comes out of the box and the user is not even given the option to disable it during the initial setup," the NRDC wrote. The new prompt directly addresses this criticism (Side note: Microsoft says instant-on mode uses 15 watts).

Existing Xbox One owners can make the power switch themselves by going to "Power & startup" under Settings. Change your power mode because you want to save some cash, because you're thinking about the environment, or if you want to hear your significant other scream "XBOX, ON" tonight in increasingly frustrated tones before they figure out it's just not going to happen.
