> windows is idling at less than half the power! Idle power matters since most laptops spend most of their time idle waiting for the comparatively-slow humans to press keys The min use under Windows is slightly lower, the average is higher, and most importantly of all, the battery life (the metric we actually care about) appears about the same. As the article says "Overall, the power use between Windows 10 and the four tested Linux distributions was basically on-par with each other." and "Beyond this data, the battery life of this Dell XPS laptop has been about the same as seen under Windows 10 with the testing thus far. So overall it's a pleasant surprise with not having tested any other Kabylake-R laptops and wasn't quite sure if the Linux power efficiency would be able to run on-par with Windows 10 at this point." So it would appear that your new claim (that Windows gets twice the battery life) is without merit. I wish laptops were like a phones, where race to idle is key, but they're not. The upper levels of the software stacks both on Windows and Linux aren't there yet.
