    I'm running Battery health app and cocunut battery for macbook retina to measure my battery but my Battery charge ( current charge ) doesn't charge up to 100 %..

    So my readings in Battery health app after a full over night charge are like this -

    Battery charge
    Current charge- 97.9 percent ( 8360 mAh ) for the current charge

    Battery health
    Current max: 8545 mah
    Original max: 8460 mah

    I know that Battery health capacity.. the current max decreases over time.. but shouldn't the Battery charge ( current charge ) still be able to reach 100% ?

    That is normal for it to fluctuate around the 90%+ range, particularly if you have not discharged the battery very much during the last round of use.

    Run it on battery down to 60& or so and often you will see the next recharge come up closer to 100%.

    Nah, that is common in the readings even when at full charge

    Most devices dont get to 100%... Its a common thing.

    No need to worry, just enjoy!

    It's normal that your battery may stop charging between 93-99%. For details, read the CHARGING section of the following link. This should answer most, if not all, of your battery/charging questions:
