Hey everyone...I've been looking around and can't really find anything, so I'm bringing it here. After noticing some depleted battery life and missing a calibration or two, I decided to run Coconut Battery. I was told my battery capacity was at 77%, so I did a fresh calibration. Now I'm at 75% capacity with a 13 month old Macbook. Is this about what I should expect at this point? Thanks for any info.
