Hi guys I've got the 15" MBP with a Core i5 and I've nearly finished calibrating the battery. After the MBP became fully charged, I left it for 2 hours, used it a bit, then shut it down. I've been using the MBP as much as possible (to discharge the battery) for a few days now. But I have been shutting the machine down when not in use. Currently the machine is resting with 0% charge for a minimum of 5 hours (like Apple suggests). I'm wondering if by shutting it down those few times, will it affect the battery calibration?
