    My 2011 MBA 11" MC969LL/A is still pretty new and has only 8 charge cycles. But my battery capacity in both CoconutBattery and iStat both show it as being at 95%! Is something wrong? Maybe I should take it to the local Genius Bar to have them take a look at it? Just seems like too much of a drop in such a short period of time. Thanks.

    It is perfectly normal if your battery health (maximum capacity) is less than 100% when new or if it fluctuates up or down over time. For further details, read the CHECKING STATUS AND HEALTH section of the following link.

    This should answer most, if not all, of your battery questions:

    It will fluctuate a little bit up and down, I'd give it a bit longer and a few more cycles and see if it comes back up or stops dropping.
