I bought a 13' MacBook Pro three weeks ago and it`s battery capacity is already 93%. I just saw a six-month MacBook, with 36 loadcycles, whose capacity is at 96%

I'm worried because I bought this model just thinking in Battery life...

I already read this guide and done a calibration some days ago, but the battery capacity kept decreasing.
 
My 1st generation macbook with nearly 700 cycles is reporting 94%. I'm still using the battery that originally came with it.

Did you read the section "CHECKING STATUS AND HEALTH" that talks about the fact that it's normal for your battery health to fluctuate over time?
 
I'd say not to worry about it too much.
I have had 58 battery load cycles and already at 91%
Also had done calibration once to notice it went down even more,ever since that i have stopped worrying about it.
 
My 15" Hi Res Glossy 2.66Ghz i7 did the exact same thing but it was at 93% for nearly 4 months and then it went to 94%, weird. :confused:

The battery status is Normal.

I'm going to wait some weeks. If the capacity keeps decreasing I'll call the local support (I live in Brazil).

If you're worried get that fawker replaced. My 08 aluminun unibody has over 500 cycles and it's at 95+ % depending on how my wife cycles it. Do I feel lucky? YES! My 2010 and 2011 MBP is always at 99-100% :D
