    i have a macbook pro, and according to coconut battery, my battery health is 95% at 15cycles, it's partly my fault because i haven't calibrated it for 2-3 months, so last night, i calibrated it, i followed the instructions at apple website, and after, my battery health is dropped to 94% at 16cycles, why is that?

    Calibrating the battery merely gives your computer a more accurate idea of what capacity your battery can hold. Perhaps it was just a little too optimistic pre-calibration...
