    Hi All,
    Is this common with my 13" MBA battery 2010?
    145 cycles; health 90%; 6024 mAh full charge capacity?
    I often calibrate battery once per two months.

    How it will remain 80% after 700 cycles like Apple commit? :eek:

    My guess is that the health might drop quicker at first, and level out. So it will drop slower and slower as you approach 80%. But that's simply my guess.

    Obviously you'll want to make sure you try to do these things to keep the health as high as possible for as long as possible:
    - operate your Air plugged into the wall whenever you can, to avoid having to use the battery all the time
    - store the air at approximately 50% battery charge (or close to that) if you're leaving it off for a long period of time (ex. a week or so)
    - avoid draining your battery fully; turn off your Air somewhere between 7 and 10% battery charge if at all possible... if not even slightly sooner (10-15%)
    - calibrate your Air every month or two if you like (but not often)
    - store your Air in cool areas (never hot areas) if at all possible
    - if gaming or doing high-heat (highly demanding) work on the Air, try to be plugged into the wall to avoid using the battery... draining the battery quickly through one charge is likely a little harsher on it... also when your Air is hotter, your battery will get hotter... if your battery is hotter, it's just slightly worse for it

    Lol. By "often", I think he means "on average".

    :p

    Really? I should use direct power source for battery? It is easy! :confused: Currently, after fully charge I unplug then use until 25% and I replug. According to someone comment.

    I often charge before battery reach 23%.

    Thanks

    Read the CALIBRATION section in the link below.

    It's normal for your battery health to fluctuate up and down over time. And it's 1000 cycles, not 700. This should answer most, if not all, of your battery questions:

    Thanks, it's clear.
    So from now on, I will leave my MBA plugged more often.
    And only drain the battery around 50% each 3 days.
