I use Ubuntu on a tricked out yoga 900 and I plug it in about once every two days or so when I'm using it somewhat actively. At full charge it reports having 9-11h of charge, but I've never verified that that's accurate. I haven't really felt much need to because that's pretty much a "don't worry about it" amount of time between charges for me. Mind you it doesn't have a dedicated GPU, but I would avoid that like a plague on a laptop running Linux for various reasons. Intel graphics tend to just work.
