I purchased my MBP about a week ago now. Ive fully calibrated the battery, but I cannot achieve a 100% charge. It stops and says the battery is fully charged at 98 or 99%. Battery has had 2 cycles. iStat Pro shows battery health at 94% CoconutBattery shows the Battery Charge at 98% (even though its plugged in and fully charged), and the battery capacity is 93%!! Do I have a battery issue??
