power-profiles-daemon is used by GNOME and KDE yet the article reads as if this was ubuntu only.
- It's omgUBUNTU, you know.
  
  As a non unbuntonion it did make me go "omg, wtf?"
  I thought the whole point of these debian variants was to add useful stuff like that - faster then debian.
- It's an article about Ubuntu 24.04 on an Ubuntu-centric blog. It's looking at that particular OS and whatever the OS uses. It doesn't use KDE and it doesn't use vanilla GNOME. As an Ubuntu 22.04 user who's considering upgrading to 24.04 and is curious what's in it, the fact that PPD is used elsewhere is a mere coincidence. 😊
- Yeah Fedora uses that since forever and will even switch away from it in half a year or so, to tuned.
  But a users reported way better batterylife on Ubuntu than on Fedora. So maybe they do something better?
  
  what are they switching to?
- Yeah I'm pretty sure this has been in debian for a while now

Good change. Balanced mode being battery-unaware prior to this isn't ideal.

Still far from ideal, though. My 2017 MacBook Air with a severely degraded battery lasts 4 hours on macOS, but only 2.5h on Ubuntu 24.04 using the power saving profile - and that's with less intensive usage, as macOS keeps rendering gaussian blurs everywhere and launchpad and spotlight and all those annoying services.
- Well this change can't improve anything about Power Saver. It only affects Balanced which now should be a bit less of a gas guzzler.
  And yes, even the most aggressive power saving we have at the moment isn't anything to write home about. If we paid 10 developers to hunt down power drain issues and submit fixes for a few years we may get closer to macOS. 😂
- The great irony is, when I ran Windows native on those Intel Macbooks, I was getting better battery and performance than with macOS.
  
  Not sure why your comment was downvoted, you're actually correct, Windows is got better battery life. The only reason I'm not running it on this MacBook is an unpatched bug in the Intel HD Graphics driver that prevents it from working with newer Windows versions on MacBooks with this specific display adapter.
