I'd also be interested in it. I got a work laptop that has a good battery, but it's an i7 and I mainly need to SSH and use FF, so I think I could undervolt/underclock quite a bit.
Ubuntu has some pretty sensible presets for that, I use them by default when I'm on battery. It's called power profile and there is performance, balanced, and power saver. The only application where responsiveness really suffers is gmail 🤡
Pretty sure those are present in other distros, too. My understanding is that they really just limit per draw.
Too bad I use Arch (btw) ^^
You can use it on Arch too. It's probably worth checking out the whole Power Management page on the wiki, but in short, the major desktop environments all have hooks for these options, and there are a lot of options for supplementary packages to power-profiles-daemon that you might find helpful.

Thank you, I'll check it!
