Hi all - First, this brand new Ultimate MBA 13" is my first Mac since 1996 or so. What an amazing machine and OS. I'm kicking myself for waiting this long to get back after years of 'getting by' with Windows and Linux. Now - my issue - I am absolutely amazed at how poor my battery life is. My best runtime at this point is 4 hours, doing exclusively web browsing via WiFi. Far cry from the 7 hours I was hoping to at least "get close" to. I've been troubleshooting to the best of my ability and can't find anything close to a smoking gun. 1) Activity Monitor is almost ALWAYS > 90-95% idle process. I've never seen a situation when my MBA is heavily CPU utilized. 2) The battery looks fine in System Info - 6750 mAh at full charge. At this point I'm at 5 cycles so it's obviously a brand new battery as I would expect. Any suggestions in further troubleshooting this? I really don't want to deal with any Apple Geniuses on this one and don't like the idea of returning what is an otherwise amazing machine.
