First, happy new year 2016 to everybody ! Globally, the desktop computers with Linux don't save the battery so long than those with Windows, (and maybe than those with Mac Apple) : about 3 hours with Linux and more than 6 hours on Windows. (no test with Apple). This is a (rare) serious inconvenience for Linux. The kernel doesn't manage correctly the energy usage of the battery, compared to Windows. Hope it will better in a few months, this is important for the travellers. André
battery life was definitly better in squeeze with 2.6 kernel, got ~ 5 hours from my x61, now on devuan I get ~ 2 hours out of the same battery capacity. Nik
My kernel version (Jessie) is 3.2.0-4-686-pae, and I don't observe a good energy usage of the battery, always very lower compared to Windows and my desktop is recent (april 2015).
