I think using a more lightweight WM would certainly help. I don't have any problems with battery life using XMonad and debian.

Interesting. I switched a laptop from Windows to Linux, and I would expect the battery life to be roughly similar even with a heavyweight desktop. It wasn't, battery life cut in half.

Of course, that's a statistical sample of one and it was four years ago. Maybe a newer kernel or different hardware or both would make a substantial difference.

Yeah, there's no real reason it should be but KDE was always a hog like that IME. Could definitely be worth trying again and maybe seeing if you like any of the more minimal desktop envs/WMs (XFce, iceWM, XMonad etc). I love how blazingly fast a minimal linux setup can be even on old kit, and battery life is correlated to that.
