Got my MBP almost two weeks ago. Calibrated battery same day and since then I've noticed the battery health keeps going down. Coconut Battery said 100% health, Full Charge Cap. 6530 mAh on the first day. Now it says Full Charge Cap. 6200 mAh. Right now there is only 9 cycles. I had a 1.5Ghz PB before this and after 5 Years, the battery is at 84% health. At the rate this MBP is going, I'm a bit worried. Should I give Apple a visit?
