    Hi, I am new the Macbook Pro and have questions regarding battery needs your help.

    1) If my MacBook Pro is fully changed and I plan to put it to sleep mode, do I still need to let AC adapter plug in?

    2) Let the computer to sleep or turn off is better when I don't use it?

    3) What's the normal "Fully Changed Capacity"? Because I saw it changed from time to time when I check in "Apple system profiler"?

    Appreciate your views and answers to the above questions. Thank you very much in advance!!! :)

    1) If you put it in sleep mode, using the AC adapter isn't necessary but know that in sleep mode, your battery will drain x percent per hour.

    2) Up to you, neither choice hurts your computer in anyway.

    3) For the new MacBook Pro, IIRC, the Full Charge Capacity should be somewhere in the 7000 mAh range.

    You can leave it plugged in, it won't hurt, but it does use a little power while sleeping.

    I usually just sleep mine, unless I know I won't be using for a few days.

    Nah, no need for that. It will go down to about 95% or thereabouts of original capacity pretty quickly, but it stays around there for quite a long time. I got my computer about 16 months ago and it still is at 96% battery health.

    Sorry, didn't know which model you had.

    The 13-inch MacBook Pro will be in the 5700 mAh range, the 15-inch is in the 7000 mAh and the 17-inch is likely bigger than the 15-inch.

    As for the fluctuated reading of your battery, calibrating will help give a more accurate reading. Also, different readings is completely normal.
