Noticably lower standby battery drain with Fedora 40
Noticably lower standby battery drain with Fedora 40
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?
You're viewing a single thread.
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.
There is a threshold parameter you can tweak
Please keep in mind that staying between 20-80% greatly improves battery life.
Thanks. I've been able lenovo's charging threshold feature and it won't charge past 60%.
