    I've experienced, in the past, chargeable tech that would somehow impact battery life if it were left plugged in ALL the time. I'm the kind of macbook user who will likely use it, plugged in, about 85% of the time. Does the macbook automatically bypass the battery once it's fully charged? I don't want to impact my battery life by leaving it plugged in all the time.

    A note: When I DO start running it off battery, I'll usually run the entire battery out before plugging it back in... just because I know that full cycles are healthy for batteries rather than skimming, say, 20% off it, then plugging it back in.

    It is no longer necessary to do full cycles. Just use the batteries as you need, while making sure you use them at least occasionally. And it's probably helpful to calibrate once a month.

    Just be sure to full charge, full deplete until force sleep, and full charge at least once a month.
