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 can’t speak on which is the best. I haven’t compared them on modern systems.
But what I will say is make sure you’re not artificially limiting your power levels or clock speed too much. Big fat Intel CPUs like that are power hogs when active. They need to reach an idle state. I have a laptop with an i9 11950h which is the same thing. But with the power plan on the lowest I get worse battery life and performance than if I just left it on balanced. But it depends on the workload. If there is no idle then power save might be best. But if you’re browsing the web and not constantly scrolling then balanced might just be better.
