    I recently got a great deal on a MacBook Air Mid 2013 model 11 inch Base model for 680. The machine is simply amazing but I'm still confused on the whole charging process. I've had the laptop for a month and my rundown on charging is keeping it plugged as much as possible, and every week I would use the macbook for as long (1-2 days, only use it for about 2-3 hours a day) as I can off the charger until it hits 50-55 percent then redo the process. Is that an okay process? if not please tell me what you can recommend to keep a healthy battery, I need this macbook to last 4 years until I get my BSN. Please be nice to me as well, I'm a new user. Have a good one guys and thanks for reading.

    Go ahead and run it down to single digits then plug the charger in. I do this once per month with our mac laptops and it seems to keep the batteries happy.

    I find doing whatever I want with my computer is the best way.

    I had an old Mac that I tried to "maintenance" the battery; battery had less than 50% health in less than a year.

    Now none of my Macs have issues once I started using them like and giving a hoot.

    I just looked this up the other day because I just purchased a 2014 MacBook Air and I wanted to see if I needed to to anything special for the first charge and I came across this... http://support.apple.com/kb/HT1490

    The MacBook Air falls into the category of "Portables with built in batteries".

    The batteries in MBA, iPads and iPhones work optimally when between 40% and 80%. My typical use, then, is to use the MBA until it reaches in the 40% range and charge it to full overnight. In the morning, I unplug the charger and just let the thing sit until I use it again. It is best to let the battery sit off the charger than on when considering longevity.

    I don't worry about dipping below 40%, but I never work the computer so long as to let it die because of the battery, this too can degrade the life span.

    I've had a 2013 MBA since July (so 11 months) and this is what I've found.


    I use it during the day at work off the battery and it gets as low as 20%.

    I go home and charge it for a 1 to 2 hours and then take it off charge.

    My cycles are 146 and battery health fluctuates (this is normal) around 96/98%

    On the occasionas where it's been left on charge overnight the battery health has dropped significantly, most recently it dropped from 98 down to 90%.

    This has steadily increased again over the last week back up to 96/98%.

    I'm fully aware that most people say it doesn't hurt it to be left on charge overnight etc but I'm going to continue to take it off after a few hours.

    It helps the MBA charges so quickly too :)

    What do you mean 'work optimally'? How is the battery going to work better at 60% than at 95% or at 30%? Either it is supplying power to the device or not.

    Also, where did you get this information from?

    Thanks.

    This. This seems to work the best.

    I used to be very concerned about this too. Back when I had a laptop with a removable battery I used to take the battery out when the computer was charging to preserve battery life.

    I've had the 2013 MBA since august. Here is how I use it:
    plugged in most of the time at work.
    Unplugged often at night.
    sometimes left on the charger overnight
    sometimes I forget to take it out of my bag when at home so it is off the charger but then it gets plugged back in at work
    Frequently I need to work away from my desk and then I use it for 1-5hrs off the charger (because I can't eat in the same space where my desk is :()

    I usually don't make it to 50% discharge before charging back up. But occasionally I get down to 35%. Sometimes I accidentally forget and plug back in at 80+%

    None of it seems to matter. Battery health as of right now:
