    I have a brand new Unibody Macbook Pro and at 87% I am seeing only 1:19 available... in osX I am seeing approx 3:58

    Is this just Windows being a powerhog?

    I am running High Performance in OSX (the GT card)... so it's not that...any ideas?

    You are using the 9600GT video card in XP also. That can cause a drain

    Edit: Never mind, didn't read the entire post.

    XP/Vista has a poor power management over OSX on these notebooks. Its proven in Windows, the battery life is slightly -> drastically less then OSX. I get about 2.5 hours in Vista x64 while in OSX I can get closer to 4-5 hours with doing the same thing + same brightness.

    Maybe it's just me, but when I try to dim the screen in XP it doesnt stay dimmed. So yeah, I get less battery life..
