Hi guys, I just got my first Mac. My first reaction (for the first week anyway) was how amazing the battery life was. It could last 8+ hours. Now suddenly (it kinda happened overnight), I cannot get more than 4 hours! I have no idea what happened. I have not installed/deleted any new apps! All the brightness settings etc are the same. Searching on the internet, it seems that Mountain Lion is at fault..? My Air came with Lion and updated to Mountain Lion on the same day. The only thing that has changed is, I am getting more notifications (I added some Email accounts) than before. Could this be the reason?
