To this, we'd add our own recommendations: it seems clear that Microsoft's own Quiet Hours feature on Windows Phone 8.1 could be adapted to the Xbox One. Simply set a time during which the console drops down into a low-power state. And if an insomniac wanders into the room at 3 a.m., let it take a minute or two to warm up. Or use the person's Windows Phone to sense when he's at work, and do the same.
In any event, only the Wii U comes off favorably in the report, earning praise for improving graphics while cutting power. Unfortunately for Microsoft, the One has been criticized for taking its focus away from playing games, including charging for free entertainment apps. Apparently that will hit One users in the pocket with higher energy bills, too.
