    I'm at 89% macbook pro retina 2015 13" bought March last year 117 cycles. I started with 6500 mAH I'm at about 5800 ... I haven't treat battery wrong, I just used it normally, why I'm so unlucky??

    I wouldn't worry too much about it yet... it is normal for the "health" indicator to fluctuate a bit during normal use. I wouldn't be surprised if you saw that number jump back up into the 90's after a few more cycles. Also, Apple will replace the battery if it will no longer hold 80% of design capacity within 1000 charge cycles (provided you are covered under original or extended Apple Care).

    Try draining the battery below 10% once in a while followed by a full charge. Usually it recovers.
