Interesting.. I have a new MBP and I only see 5643 mAh on mine

That's good advice. I have exactly the same MBA as you do and my battery life seems fine, too. I haven't run it all the way down yet, simply because it is too easy to plug it into the AC adapter when I don't need it. Also, I try to remember to close the lid whenever I am not going to be using the computer for a few minutes.They can hook up one of their diagnostic tools at the Genius Bar and isolate whether or not its a bad battery in like 30 seconds. I wouldn't waste a bunch of time trying to troubleshoot it yourself if you just bought it. Set up an appointment...you could walk out the door with a new one unless it was a CTO.
I played Left For Dead 2 on my 13" MBA yesterday for 3 hours on a full battery charge. My fans were whirring the whole time and even then, after that whole time, I still had over an hour left on the battery when I was done. With normal daily use, I'm averaging right around 7 hours.
Which MBP do you have? If it is the 13" or 15", that sounds about right, the 17" has around 12759mAh.
Addendum: The batter in the 13" and 15" MBP is not as big as the battery in the current 13" MBA, as far as I have gathered via tear downs.
I get 5-6 hours. But the remaining life indicator jumps wildly. One minute it says 3:50; the next it might say 10:05, then a few minutes later it could be at 2:44. Kind of reminds me of those Microsoft things when you're installing a program and they pretend to show you time remaining. they can hang at "time remaining--1 second" for 30 minutes.
The conventional wisdom seems to be that the 13 inch MBP's 10 hours of battery life, compared to the MBA's 7 hours, and the MBP's weight of 4.5 pounds, compared to the MBA's 2.9, is attributable to the 13 inch MBP's battery being larger and heavier. Is this not right?Addendum: The batter in the 13" and 15" MBP is not as big as the battery in the current 13" MBA, as far as I have gathered via tear downs.

After calibrating the battery I'm pleased to report that I'm getting 9-14 hours of battery life out of light-moderate use, and 6-7 hours with heavy use. I must say I'm pretty pleased by this little machine. Thanks for all the tips and help everyone.
