Anyone seen this? I was REALLY surprised, and slightly confused (how is Arch with LXDE better on battery than straight Openbox? LXDE uses Openbox...).

Why would Arch kill a battery that fast?

It's all very confusing, especially the conclusion.

Yeah I'm wondering that, too. It's very strange.

The biggist improvement to battery life that I have managed to acheve was by locking the CPU in its lowist clock speed, which added around 2 hours to the bettery life.

Seing as Arch is configured manually, bad battey life == bad configuration.

Funny thing: up to now I was getting about 90 seconds per % of battery life (done by the incredibly unscientific method of having a flash-page stopwatch counting until my conky showed a drop). A simple installation of powertop/laptop-mode and suddenly, gasp, I'm getting 150 seconds per %. Went from 2.5 hours estimated to 4.1 hours estimated. And this battery's not exactly fresh.
