So I’m looking for a distro that I can put on my laptop in addition to kde neon and boot into when I want to save battery. The thing is I’m not even sure if I can expect a noticeable difference or if the display and applications I want to use (mostly just basic office stuff and maybe a browser but I want to use this in the forest so I won’t have wifi anyway) already draw so much power that background processes don’t really matter. If you think they do then I’d like to hear about especially efficient distros. I’m not a poweruser though so anything that requires extensive setup or maintainance won’t work for me sadly. I was thinking maybe something like kanotix that loads to RAM but like I said I’m not sure if that actually saves power.
This isn’t really a distro thing. You’ll get the best results by turning off radios, ensuring the CPU frequency is controlled (or just locked to the lowest), and not using any 3D stuff or the discrete GPU.
To add to this, I’d recommend to go through the BIOS/UEFI settings and turn off things you don’t need, e.g. certain card slots, ports, fingerprint scanner, maybe the webcam.
