H guys

I just bought my new macbook air 2013, Do I need to calibrate my new macbook air's battery after unboxing it?

MacBook Air, iOS 7.0.3

    Welcome to Apple Support Communities


    All new MacBooks come with a precalibrated battery, so you don't need to calibrate the battery. This is only required for 2008 and older MacBooks

    No, as per Apple, current Lipo batteries in the Air do NOT need calibration



    How to TREAT your new Air batteries:


    Keep it plugged in when near a socket so you keep the charging cycles DOWN on your LiPo (lithium polymer) cells / battery.


    *Contrary to some myths out there, there is protection circuitry in your macbook and therefore you cannot 'overcharge' it when plugged in and already fully charged


    If you leave your macbook plugged in all the time, take it off charge and drain the battery down to 15 or 20% every couple of weeks or so.




    LiPo (lithium polymer, same as in your macbook) batteries do not need conditioning. However...


    LiPo batteries do NOT like to be dropped down to 15% or so often,....key word being "often"


    A lot of battery experts call the use of LiPo cells the "80% Rule" ....meaning use 80% of the charge or so,.. then recharge them for longer overall life.


    Never let your Macbook die from power, you can corrupt files that way, and the batteries do not like it.




    The only quantified abuse seen to LiPo cells is instances when  often the cells are repeatedly drained very low.


    Contrary to what some might say, LIPo batteries have an "ideal" break in period. First ten cycles or so, don't discharge down past 40% of the battery's capacity.


    Same way you dont take a new car out and speed and rev the engine hard first 100 or so miles.




    *Also, if youre going to store your macbook away for a few weeks or more,... make sure it has at least a 50% or so charge.


    *Cycle count / use/ lifespan is one thing that cant be countered.




    Proper treatment is another thing. Just because LiPo batteries dont need conditioning in general,.. does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesnt need conditioning.


    Just use and enjoy your new macbook, 


    From Apple on batteries:







    but really all you would keep in mind is --"consider 20% is the same as 0% and recharge it"


    and best "tip" is if its near a socket, .....plug it in as long as you can (especially at home) since cycle count on the battery are the "miles that wear out the tires (battery)"

    calibrating does not give life back to the battery it just syncs the chip reporting the battery life with the current capacity of the battery. calibrating is ok 1 once every 3-4 months just to sync the chip. it just doesnt revive the battery health.

  • Whizkid56222 Level 1 (55 points)

    So all in all, its not neccesary to calibrate your battery.

    No such position is to be taken, nor does Apple indicate same.



    Portables with built-in batteries

    Current Apple portable computer batteries are pre-calibrated and do not require the calibration procedure

    If you think im refering to your post, I am not. I do apologize because I replied to your post. Sometimes Im just too lazy to go all the way back up and hit the reply back to original question .Secondly, Im just informing the person who opened a discussion and asked the question my thoughts about his/her question. From my experience, a lot of people generalize that calibrating somehow revives their battery health, but it doesn't. That was the whole point of my post. The point of these discussions is to discuss, so you have no need to get upset. Posts are just everybody's opinion.

    I never mentioned battery calibration whatsoever


    I never mentioned reviving a battery,  only proper treatment of a LiPo battery

    Yes, many people think battery calibration revives or prolongs life.


    nobody here is upset, least of all myself.


    Posts are sometimes doxa (opinion), mostly however they should approach episteme/ ἐπιστήμη, or empirical fact.


    Computers and their likewise components are all quantified  = facts only.


    The opinions should come in when someone asks "what computer X or Y you think is best for me?"
