I got my rMBP with Lion, then put on ML. Will a reformat help my battery life?

    So my rMBP gets ****** battery life. Even with it on half brightness and doing basic web browsing and word processing, I can barely get 4 hours out of it. I mentioned this when I was at Apple having them replace the screen -- they tested the battery, said it was normal, but replaced it anyways (don't ask me why).

    I don't have any background processes running or anything like that, but I'm wondering if putting a clean ML install on it and re-loading all my programs might help. I'm really out of ideas, and all the reviews of the rMBP say they could get 7+ hours out of it doing things like video playback. That's nearly 2x what I'm getting.

    A reformat may or may not help. What you can do however is read through and apply the steps in this battery guide.
