I upgraded to Fedora 40 workstation a couple of days ago. I never turn off or suspend my laptop (a Thinkbook 14s Yoga) and it was guranteed to be dead if i left it unplugged for a couple of hours before the update.

With Fedora 40 it's been unplugged for almost 5 hours and still has 52% battey left (down from 59% when i unplugged the charger).

I noticed both TLP and auto-cpufreq have been disabled after the update so this looks like default power settings are being used.

I'm not sure if it means I'll be getting consistently better battery life but i thought maybe it's a good idea to share this first impression anyway.

Has anyone had a similar experience?

    It's power-profiles-daemon. The new version came out a couple of weeks back (and reached stable bascially in the same day as F40 released) with much better performance, as it now detects if your system is running on battery and adapts both the balanced and power saver modes accordingly to save on power, it's pretty great!

      Still I am finding it difficult to believe that just being battery aware has taken battery usage from 50℅ per hour to 1.4℅ per hour

        It's a lot of other big improvements. The improvements were mainly made for Framework laptops but they apply to other laptops too.

    Running Fedora as a secondary OS from a Thunderbolt SSD. What I can tell you is that my Bios still seems to be in charge (pun intended) of the charging cycles since it wouldn't charge past 80% and I never set this in Fedora.

    Otherwise runtime seems about average under use and the estimated time left on the charge seems correct.

          battery health != battery life

          just a small fix, battery life is usually referred for the amount of time you can get out of a single charge, battery health for how long your battery will last over the years maintaining its capacity

          Thanks. I've been able lenovo's charging threshold feature and it won't charge past 60%.

    That's interesting. I usually skip each other fedora version, and will probably go from 39 to 41, but if there are improvements to battery life, maybe I will try it now.
