doyougnu was previously running NixOS on a Macbook so their bar for "working" is probably much lower than a normal person's. I'm on Windows, but if a Linux could give me reliable power management I would switch in a heartbeat. I don't know what it would take to have sensible power management on Linux without major issues.

battery life with that laptop was always better on the mac, but I regularly got 4-6 hours on that machine for years, first with Arch linux, and then with NixOS.

  powertop --auto-tune is kind of annoying to use, it usually winds up tuning something that shouldn't be and there's no convenient way to filter what it does, and then suddenly your mouse stops being responsive if you leave it alone for more than 2 seconds. Also on a laptop you might have stuff being plugged and unplugged all the time. Tbh it's kind of surprising systemd hasn't grown a "powertop that remembers things" arm.

I get six to eight hours on my Thinkpad, running Arch Linux. This did not happen out of the box. I think I got like two hours of battery life before I began tuning parameters. As usual, the Arch wiki is an excellent resource even if you're running a different distro: https://wiki.archlinux.org/title/Power_management https://wiki.archlinux.org/title/Power_management

  That's impressive. I've done the equivalent of tuning everything and still wound up with battery lifetime half of what it should be on Windows. There's also specific programs that are really bad. Edge used to add 2-4 hours extra battery life when using my Surface to read PDFs. If I used Firefox, it was shorter by a very noticeable amount.

    Does straight chrome have similar battery performance?
    - R0b0t1 4y ago
      Chrome was worse compared to MS's Edge, but Chrome based Edge seems worse than previous Edge. My testing isn't as exhaustive on the new Edge.

        Huh. Wonder what the secret sauce is that apparently they can't release upstream. Open source FTW?

Try Pop OS.

    Pop OS on a Dell XPS is giving me good battery life. If you already have your machine and files are backed up, worth a shot.

      I didn't have the same experience with pop on a newer XPS. I wasn't able to get more than 4 hours on a full charge.

        I’m on a 2020 XPS17. At the time I was having a hell of a time and it took almost a year for everything to be supported out of the box.

        Why do people keep doing this to themselves?! I really don't get it. Just buy a laptop from a vendor that actually supports linux, like System76.

        Because there are countries out side of America. You may have heard of them.

Have a look at thinkpads. I used x280 and x1 over the past 5 years with more than a week’s worth in folded lid sleep state.

  I own/have owned multiple Thinkpads, a couple of which run Linux. The power management on Linux is bad.

Framework boards has its own compilation of battery tweaks for linux, though I'd also recommend the Arch wiki another user posted in this thread. https://community.frame.work/t/linux-battery-life-tuning/6665 https://community.frame.work/t/linux-battery-life-tuning/666...

What counts as sensible for you? Experience differs depending on hardware. My Dell XPS 13 got 7hrs out of the box on Manjaro, which I tweaked to get to 8.5-9. On ubuntu I didn't have to bother with the tweaks. That's comparable to Windows on this device...
