    Seems slightly better on ML. But I haven't had any major issues on Lion either.

    I'm currently at 77% and its showing 7 hours and 25 minutes remaining.

    Seems worse on 2010 Macbook Air. My battery is at 91% health (6100 mAh out of 6700 mAh design capacity). On full charge iStat Menus are showing 6hrs remaining.
