Yet, it makes me feel like the situation is not changing that much on Linux for laptops: most of this should be more automated IMO.
An apple silicon MacBook Pro is quite a bit more expensive, but all of that has mostly been done for you and mostly “just work”, and there is value in that.
This is an archlinux user. You cannot automate and generalize personal opinions and settings. For 1 user that wants his screen to go down to 60Hz on battery you might have 5 who will say they can't use a computer with such a low refresh rate.
A user who wants something that "just work" would have installed his computer with the latest Fedora, Mint or Ubuntu and would be using the default desktop with default sane defaults and terminal and would have been perfectly happy with it.
Having said that, my guide does use some advanced or very recent tricks that are not done by most distros. To which extent all of that help? Hard to say, but we are clearly in the premature, but fun, optimizations territory.
Installing something like Fedora is super easy.
I'm mostly using it on my desktop, but have setup laptops for friends. Of course System76 that makes Pop sells hardware, so I'd expect them to do better than most in that space.
I don't need to do any of these things with Fedora or Suse.
Of course some tweaks might actually have an effect. There are probably actual differences between different pstate driver modes or governors. (But even then it might be dubious whether you need to or should tweak them with TLP since power-profiles-daemon should supersede it in terms of energy/perf policy.)
Pop! OS, Ubuntu, Fedora, & Mint have each been tested and had similar flaws, although Fedora was the only one that automatically reconnected my bluetooth speakers on wake.
I'm going to use this post to more thoroughly examine what information I can learn about my laptop and see if I can uncover where the weaknesses are and how to resolve them.
If your Legion has a discrete GPU, that might be outside of the tweaks in the post, though.
