    So I just bought a MBP 13 inch, and I love it. The only thing I just noticed was the battery health. It already says 98% on iStat pro, whereas my previous mac was 100% 150 cycles in. Anyone know what's up, or is this an iStat thing? Thanks.

    Not trying to alarm anyone, but maybe getting the first new batch is defective or something.

    No it is not defective. The old MacBooks had an original capacity that were 500+ more mAh than the original. The new MBPs have a capacity that is closer to the original battery capacity which is 5450 mAh*

    My current battery cycle is only 1 with 5617 mAh Current Capacity.

    Edit: Also try calibrating your battery the first time you use it.
