I'm also not sure that lots of the stuff in the optimization part is actually needed or useful. A lot of it seems like micro-optimization. The author probably cares a lot about tweaking his laptop. If you want to do those steps just in case they might gain you a bit of battery life, you can do them. If you don't care about compiling your own kernel for potentially getting a 1% longer battery life, the vast majority of that stuff shouldn't be needed.

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.)

I'm not an Arch user, but I have noticed pretty poor battery life and sound volume on my Lenovo Legion laptop with every linux flavor I have tried so far.

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.

Yeah, there could be some useful tweaks. I started getting much better battery life on light to moderate load on my ThinkPad when I switched the AMD pstate driver to passive mode. I don't know if that has performance implications but responsivity seems fine to me.

If your Legion has a discrete GPU, that might be outside of the tweaks in the post, though.
