As a long time apple user, I finally made it back to getting an MBP after several years of being forced into windows. I bought a brand new MBP when i turned it on the Battery would only hold 80% of the charge, and kept flashing "Service Battery" i tried everything - a Calibration, an SMC Reset, EVERYTHING. I took it back, and Apple Swapped it out. No questions asked So I got the new one home. The Battery held at 100% for a couple days, and then dropped to 95%. Now with 30 Cycles even, I am down at 90. So, with that in mind, should I do an SMC Reset and a Cycle? I have some friends who have MacBook Air's who's batteries hold 99% and 103% of their charge after 42, and 50 Cycles respectively. Do the MacBook Air's use a different higher capacity battery? I use the MBP at school, I leave it on for days at a time, and just suspend it I do lots of partial cycle charges, and leave it plugged in every night until i go to school the next morning Any ideas on how to fix this? or should I swap... again? Thanks in Advance.
