Hello, I have been browsing these forums for a while and finally took the plunge and got a new 13 inch MacBook Pro last monday. Now I have a question about battery health. Six days after purchase my health went from 100% to 95% after 6 cycles. Today, it now has 92% health after 6 cycles. ( I properly calibrated the battery.) I am using coconut battery and istat pro to confirm these readings. I would like to know if this is normal or out of the ordinary. Thank you very much for your responses. I have apple care and an apple store 20 minutes away! Stats: 13inch MBP 2.26, 4GB RAM, 160 HD.
