    If I leave my MacBook Air plugged in all the time even when battery life is 100 percent it will kill the battery quickly? (meaning like in 1 year I won't be able to get as much battery life as now) or is it true that once the battery life is fully charged, its just outlet power running the laptop and the battery is being preserved? Is it better to disconnect it after it is fully charged, then use up the battery and then charge it to 100 percent.

    I've heard for years that you're supposed to remove the battery or periodically let it run down, but on my MacBook Pro it has never been an issue and I unplug it MAYBE once a week.

    The laptop always uses the battery as it's source, even when plugged in. While the battery is in use, the charger will refill the battery. So, the battery is technically always being drained even while plugged in. But, if you remove the battery then it's life will increase as then the laptop will draw straight from the wall. The problem for you is that the MBA doesn't have a user-accessible battery.

    As far as i know, Apple's notebooks aren't affected with this issue. And also if you remove the battery, your macbook will run at a reduced speed.

    Its a good idea to run the battery once a month at a minimum. Just unplug once, do some work and let the battery discharge some, then plug it back in.

    I don't know, but look at it this way: a battery IS a wearing part and when inserted it works as an UPS, which is a good thing for the case of a power failure.
