when I using Windows 7 on my mini9, battery life around 3.5 hours, now install Snow Leopard, it just around 2 hours and when it sleep, the battery still lost the power 5% per hour. any idea for this issue? Thanks

were you doing comparable tasks in each test? Also make sure you lower brightness, turn off BT if not using it, etc. 2 hours does seem rather short.

Have no ideas about your settings or config as you offer no information. But my mini 9 runs ~3.5 on a stock battery in the config described in my sig. My battery sittings in the Energy Saver pref for Battery are: Comp Sleep 15m, Disp Sleep 1m, Auto Reduce Brightness.
