    Just purchased my 2012 Air and after my bad experiences going through batteries on the old 2006 MacBook Pro I worry about battery health.

    The Air came on Thursday about 80% charged and I drained it till it wouldn't turn on anymore. Now I plugged it in this morning at it is fully charged. I plan to drain it 100% every month at least but is it OK to leave the Air plugged in when in use? I am interested to know how much experienced Air owners use the computer plugged in versus on the battery?

    Thanks in advance

    There is no need to drain it. I keep mine plugged in most of the time, but have never had an issue with the battery except on my very first MacBook Air, which needed a replacement for a defective battery cell after about 6 months. Every one since then has been fine.

    FWIW, these are Apple's recommendations for notebook batteries:

    Having said that, mine's plugged in 99.9% of the time, and I'm pretty bad about remembering to drain it once a month. My Air is coming up on a year old, and iStat reports the battery health at 95%, with 18 cycles.
