I just calibrated it Saturday night even. And now coconut battery says it only has 92% (istat agrees with coconut battery). It's never had 100% since I had it (at best it said 97%). It's 5 months old at this point (I bought it soon after they introduced the new MBP). Coconut battery and istat say 13 battery load cycles (oh, and the battery can never keep 100% charge even when plugged in). Should I bother talking to the apple "genius's" about this?
