From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Noticably lower standby battery drain with Fedora 40 (lemdro.id)

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.
