This has everything to do with the unresolved problems of Linux power management. I use Ubuntu on Thinkpads too, and battery life is decent after a bit of configuration. Windows meanwhile gives all day battery life on Thinkpads.
- nextos 7y agoI have managed to achieve the same battery life, down minute differences in the single digit either side, between macOS and Linux on a MacBook Air (which is a simple all Intel machine). I think the problem is that most distributions ship with no Powertop or udev rules, plus lots of unnecessary services and devices on by default. One really nice thing Apple does is optimizing Safari for battery life. My comparison was Firefox on macOS vs Linux. With Safari, I'd get 20-30 min more. I bet Firefox and other programs would benefit from some black-box GCC/LVM flag optimization to improve battery usage.
- nicoburns 7y agoFirefox on Mac's big battery life problem is apparently lack of integration with the system compositor. There's a fix in the works for this. Although I expect safari will still be better in this regard. Safari is pretty impressive.
- rocky1138 7y agoThere is definitely an opportunity for a distro directly aimed at laptops and/or providing the maximum battery life.
- tachyonbeam 7y agoIt's really surprising/annoying that this isn't setup correctly by default. Linux on laptops is nothing new.
