Hi everyone! I have been using Fedora since the first beta of 34 on my previous laptop. I recently switched to a Dell XPS 15 (9500) and I’m having battery life issues and high power consumption (which are oc linked).
I ran F34 for a few weeks and saw that, even on idle, my temps were around 40/44°C with an estimated battery life of 6 hours (I was on the desktop), and higher on load of course. I then decided to try F35, same issues. On all my tries, I’m using Nvidia’s proprietary drivers with hybrid graphics.
I tried installing powertop (running auo-tune), TLP and preload : didn’t change much.
I am currently on Ubuntu 21.10 (running GNOME 40.4). On this setup (with the same softwares installed, basically the same setup as on Fedora) my temps are around 24-29°C and on idle (just the desktop) Ubuntu estimates 37 hours of battery life.
On my usual use, Ubuntu offers a much higher battery life than Fedora.
Any idea on what to do to get as much battery life on Fedora as on Ubuntu ?
