A few days ago both Phoronix and OMGUbuntu ran articles saying Fedora has done a ton of optimization for power saving, plus some bullshit claiming you have to use Fedora to get the battery life improvements. Fedora’s Power Tweaks Dropped The Power Use On A ThinkPad By ~30% https://www.phoronix.com/scan.php?page=news_item&px=Fedora-Battery-Numbers-2018 For Better Battery Life on Linux Try Fedora http://www.omgubuntu.co.uk/2018/02/better-battery-life-on-fedora-linux Which is total bullshit, honestly. Because Ubuntu can do it too.
