    Laptop: Mid-2012 MBA, 5 weeks old
    Battery capacity: 6362/6700 mAh (95%)
    Battery cycles: 54

    I did use ML for a while, but currently using Lion (after reading that ML was slowly degrading batteries).

    Please post a screenshot of your battery capacity (if you want).

    It is perfectly normal if your battery health (maximum capacity) is more or less than 100%, even when brand new, or if it fluctuates up or down over time. For further details, read the CHECKING STATUS AND HEALTH section of the following link.

    This should answer most, if not all, of your battery/charging questions:

    Two suggestions.

    - Go to Apple.com/support
    There you will find battery guides with every last detail you need.

    - Once you've read that, just use it, enjoy it, and don't worry about the battery. They're very long lasting.

    I've had my MBA for about one month and have 10 cycles used. From what I understand, the MBA battery is good for ~1000 cycles.

    Macbook Air 13' i5 processor.

    Battery Age: 7.1 months. (Bought it in March? 2012).
    Battery Cycles: 26
    Battery Max Capacity: 6493 mAh
    Battery Original Max Capacity: 6700 mAh

    Battery Health %: 96.9%

    Spends most of its life plugged in - making sure to drain to 50% at least once every few weeks. I've only been watching the battery health for the last few months and it fluctuates between 96.5% and 96.9% and hasn't changed at ALL no matter what I do.

    Like the poster ixodes said - just forget it, use it and enjoy it because by the time it gets anywhere near used, you'll be looking to buy your next laptop.

    Yes, you're correct - we should get 1000 cycles before getting to 80% capacity. 26 cycles in 7.1 months ... my laptop battery will last longer than I'll keep it.

    Exactly. I removed the Battery Stats on my iStat Pro widget. I even disabled Battery Percentage. LOL

    The application is called CoconutBattery - it's in the title bar of the screenshot. Google away.

    No need to Google. The link to that and other apps are in the Battery FAQ.

    Mine was at 98 and I let it die down and recharged and it was up to 99. I think it fluctuates a bit. Week old MBA if it means anything.

    There's no need to let it die down and recharge intentionally. Read the 2nd post of this thread.

    I wasn't necessarily trying to calibrate it.

    From the 2nd post:
    I usually use mine plugged in, so I ran it down a bit to get the electrons moving ;P

    I didn't think you were, since that's not calibration. I was referring to intentionally cycling the battery in an attempt to affect its health.
    The 2nd post confirms it.

    There is also a clone of Coconut Battery in the MAS.

    78% capacity on my 2007 MacBook. Not so bad for a 5 year old machine.

    I stopped worrying about battery and hard drive space a long time ago. I was one of those guys who, throughout high school, plugged his laptop into every outlet in every class, including my cellphone to keep everything 100% just in case I needed it. It wasn't an easy life.

    Just using your laptop, turning off the battery % on the iPhone and on my Macbook has provided a much more enjoyable user experience, and because of my past, I never fall below 50% even with my usage. I don't feel like I'm murdering baby kittens every time I sit on the couch with my Macbook Air unplugged... Really a new experience. lol.

    That said, when I found out about Battery Health - I cycled my battery to try to get a higher % only to see it drop a %. lol. Just enjoy the dang laptop. -- Very cool to see what the life is like after many months/years of usage tho. Awesome thread!

    Thanks guys

    My current battery health is at 97.4%, and I only have it for two days and 4 cycles. Is this normal?
