>The reality is these Intel processors are just a big inefficient hot mess. Well that may or may not be the thruth but Linux and the cpu itself has sweepdstep, which can and should clock down to like 800Mhz when idle saving a lot of power. What I found the biggest drain was the display. Dell XPS 15 is a nice (linux) machine, almost everthying works out of the box, BUT the battery life is a joke. The 4k display is the biggest betteryt hog here (check with powertop). Also I do not understand why the manufactures build muxless machines for dedicated GPUs.I want to disbale nvidia complelty, unseen on the PCI bus via bios setting....
