how can I optimize performance and battery life on fedora? battery life is way worse that what i would get in windows and the laptop is almost constantly at 98+ c its a yoga 9i with a 11th gen evo i7
Is there a dedicated gpu on this one?
First thing you could start with is undervolting the cpu and tlp. Those two actions usually get me within a stone’s throw of windows battery life and perf.
nope its the 14 inch model so no dedicated gpu just xe graphics I trie using tlp don’t know if I configured it right though tlp · GitHub
Ah, I’m not familiar with that GPU.
Okay, so that configuration looks fairly solid.
Next step would be to play around with the undervolt settings:
On my 8350h xps 15, I can get -120mv. I’d start with -50 and see how far you can go. I use stress-ng to test.

cool thx
that’s intel’s new integrated gpu its supposed to be pretty big upgrade from older intel graphics
what mainly concerns me though is that the laptop is frequently going to 98 c ish and sometimes all the way to 100c (although only when charging so maybe normal i think this also happens but less frequently on windows)
That’s just laptop CPUs. the intel-undervolt tool I linked you allows you to set an alternate max temp, so if you want it to just go HAM until you hit X temp, you can. For example, I’ve got mine set to 80c. It’ll boost to 4.3 until it hits 80c package then it starts backing off until it hits equilibrium.
But I also detuned the CPU from 45w to 30, since I don’t use my laptop for super-intensive stuff.

TLP and it’s auto-calibration is by far the best thing you can do to reduce idle power consumption.
