Improving Linux Laptop Battery Life

Reducing Linux Power Consumption


Modern laptops can use a lot less energy then laptops from a decade ago. But in order to actually get this low energy usage the operating system needs to make efficient use of the hardware. Linux supports a lot of hardware power-saving features, but many of them are disabled by default because they cause problems on certain devices or in certain, often corner-case, circumstances. This talk will describe and look into recent efforts to enable more power-saving features by default in such a way that this will not cause regressions. The end goal of these efforts is to shave of at least 2 watt of the typical idle power-consumption of 6-9 watt for recent (Hasswell or newer) laptops. The goal is to achieve this saving on an OOTB Fedora Workstation install without the user needing to do any manual tweaks.
