On August 28, 2009 I installed Snow Leopard on my MacBook Pro (15” Unibody) and something horrible happened. My battery life dropped from somewhere around 4-5 hours to somewhere like 2-2.5 hours. It was annoying, but I’m never more than a few feet from an outlet, so it didn’t really matter.

Well, the other night I finally got annoyed to look into this a little bit, and the solution was super simple.

I just had to reset the PRAM. I wasn’t actually getting less battery life, my battery was just reporting that I was getting less battery life.
