There are lots of little tweaks that can make a huge difference in battery life. Since there's a lot more that was posted on the Framework community I use that as an example (but it can apply to any laptop model). OOTB, reports for idling was anywhere from 7-11W. With the Framework's 55Wh battery, that would mean that it would run down in 5-8h at complete idle (oof): https://community.frame.work/t/issues-with-power-usage/12261 https://community.frame.work/t/issues-with-power-usage/12261 https://community.frame.work/t/nixos-power-consumption/6339 https://community.frame.work/t/nixos-power-consumption/6339 However, with some tuning, that can get down to as low as 2.5-3W: https://community.frame.work/t/linux-battery-life-tuning/6665 https://community.frame.work/t/linux-battery-life-tuning/666... https://community.frame.work/t/battery-life-impact-of-ram-memory-configuration-extra-data/6426 https://community.frame.work/t/battery-life-impact-of-ram-me... To summarize on the configuration options, the biggest gains are probably from powertop/tlp tunings, PSR, settings to get to C9/C10 on idle (PSR is a prereq for this), replacing PulseAudio w/ Pipewire, modifying the EPP values, and fstab options (noatime, relatime). Of course, some of System76's gains could be spending some extra effort on their EC/BIOS tunings, or on the hardware itself (lots of ways to mess up or to get gains from the motherboard layout/components). It's also worth noting that some SSDs like the Hynix P31 consume much less power than others, so hardware selection can play a part as well.
