Why does my newly bought Macbook pro 13'' 2012 battery has a hard time reaching 100%. It reaches to 100% with a longer charging but then falls down to 99% in a few seconds time. I have heard and read about calibration. But I think that the computer is young (only 4 weeks old) to be calibirated. What might be the issue here? This problem started just recently.

MacBook Pro (13-inch, Mid 2012), OS X Mountain Lion (10.8.3)
