    I just bought my macbook last week.
    And now I left it on the power adapter during this weekend..
    But I just notice it is only 99% charged after leaving 2days on power adapter..
    Health: 98%
    Cycle: 3
    Charge: 99%

    Is that normal??

    I hope it's normal. I have never seen the battery percentage go to 100%.

    Yup, I installed the battery update right before I first charge and calibrate my battery..
    I hope it will fix after I discharged it down to 50% later next week...

    Btw, if Im going to leave the power adapter on for like 3 days, show I take out the battery or leave it in?

    I could be wrong, but I think your supposed to take the battery out if your going to leave your laptop plugged in for an extended period of time.

    Look here:

    This is normal for all laptops with Lithium ion style batteries.

    You also do not need to remove the battery if it is going to be plugged in for a extended period of time. This was true for older batteries but not Lithium ion.
