Currently I have only one laptop, I use it for everything and it has an nvidia gpu and a 11th Gen Intel® Core™ i7-11800H. I have a mode which disables the GPU which i use when i am out and about. However I want to minimize battery use to a significant degree, so which out of the three should I have on? power-profiles-daemon or autocpu-freq or tlp, which is better for battery performance? I know ppd is configurable via desktop, so i have kde set to power saving mode, but I still want better if possible, is there something more i can be doing with ppd or would autocpu-freq or tlp work better?
I would also like to know, I heard from somewhere that power profiles deamon is the modern solution and the other 2 are older, but all 3 are still supported so I think its personal preference. Tlp has more finegrained contol, and ppd has better defaults and “just works” for me, no idea about autocpu-freq.
