    Hello,

    I am about to purchase a new rMBP.

    I am wondering if the battery has to be somehow conditioned and how.

    Could you please advise your suggestions?

    Thanks a lot,
    Daniele

    No, just use it and charge it as and when you want/need to. I wouldn't leave mine continually connected to the charger for days/weeks on end but then mine never gets that chance :)

    As mentioned, use it and don't worry about it. Unplug from the A/C from time to time as well.

    If you click through all the info at Apple's recently updated battery information page, it no longer says to do that. Maybe they determined this was causing unnecessary battery cycles.

    Thanks everybody for the kind replies.

    Shall I in your opinion keep the rMBP plugged in or shall I use it with just the battery and change it when it is flat?

    What do you recommend? Please advise.

    Thanks, daniele

    According to Apple's latest info at that link, just use however you need to. If you need to be portable, run on battery. Otherwise, just leave it plugged in.

    You don't want to intentionally run it all the way down to zero though if that is what you meant.

    Thanks for the answer.

    Yes, I meant that.

    So it will not hurt if I leave it plugged in when I do not need it portable. Great!

    "No, just use it and charge it as and when you want/need to" Apple don't give any specific advice regarding a usage pattern. <I> would periodically unplug it and use the battery capacity but that is me, as I have said, mine doesn't get the chance to stay connected to mains for extended periods.

    Nope. Won't hurt a thing.

    I've had my 2012 cMBP for two years, and it's been plugged in a vast majority of the time. The result is that I only have 18 cycles on it, with 96% of the battery's full capacity remaining.

    Point is, you can do whatever you want with MacBooks these days; the batteries don't need a certain ratio of plugged in/off the grid.

    Thanks for the replies.

    One more silly question. Anyway, when I am not using it, shall I unplug it or not necessarily?

    Mine sits on charge all night (11pm-7am) and most of the day at the office (9am-4pm), it gets about 25% drain/charge during the day and another 50-75% drain in the evenings before charging again overnight. This pattern does it no harm at all.

    Leave it plugged in whenever possible.
    Battery good for 500 to 1,000 cycles - lookup Apple battery info for your model.
    Cycling the battery every day will just use up the cycles.
    I run the battery down to 0% a few times a year - full recharge and recalibrate battery.
    I have 44 cycles after 9 months use.
    If you sell it, a wise buyer will check the battery cycle usage.

    And yet Apple says NOT to calibrate batteries that cannot be removed. Perhaps they need to update their battery FAQ's.

    Not necessary. Just leave it plugged in. It won't hurt anything.
