Hi it maybe a little early to ask this but how is battery life in OS X 10.8.3 compared to 10.8.2 and 10.8.1 for be I noticed a 1 hour increase In battery life on my 2011 Macbook air 11" I just was just browsing the web with a couple youtube videos in HTML5 do flash I had 50% brightness. Also I was listening to music when I was browsing with iTunes. And with some multitasking with Mail, Notes, Reminders, Messages and battery mini logger to log the time. When I was finished I got 4:45 mins of battery life when it died. Thats up from around 3:30 mins That I would get before. Can y'all post your stats so we can compare?
