Ordered new i5 MBP on launch day, got it week later and did a battery check. Coconutbattery showed age at 3 weeks, battery health was 100% and 1 cycle. now its showing age 5 weeks, 8 cycles and already down to 96% health. G/fs 13" MBP that I got her in mid feb has had about 50 cycles and 97% battery health. anyone else notice this, or is it normal for it quickly to drop around 96-97% health then slow its decline?
