Recently after upgrading to ML 10.8, I noticed that the battery is significantly decreasing... When I had Lion, it used to have 4 hours of battery life and sometimes 5! I am only using VLC to watch a movie and have Safari running in the background. Other than the battery problem, my laptop fans are so loud and they do not quite down. I really doubt it is any hardware problems because I had it checked a week ago for any problems. This is so weird, any help is appreciated. Thanks.
