The thing with arch is it’s mostly not more tweaks that give you better battery, it’s not having all the crap that Ubuntu preloads running that makes that happen.
Using Arch often gives me advance warning that my apps will break on users machines due to changes in libraries. I see the changes first and can add compatibility for the new library version such that it's fixed before affecting my users.
I love it as a daily driver.
Totally agree that it's a great daily driver. It has EVERYTHING!
