Hello! I've had my new macbook for 1 month and I am really enjoying it! It's been perfect for all my uses! (even gaming, lol! CS, AA, DOD) Well, now comes a weird question..... How come some people are experiencing problems with battery health while mine (knocks wood) stays at a healthy 100% and my mAH went from 5200 to 5431? Thank you for your comments!
