Long story short, is anyone experiencing battery drain even when their MBA is turned off (as in completely shut down, not in sleep)?

I ask because the other day, knowing I wouldn't by using my Air (2011 13" base model) for the next few days, I shut it down with about 50% battery life. Two days later, I go to turn it on, and it won't power on. I plug in the charger, and it finally turns on, but is displaying 0% battery life.

To experiment, I charged it back to 52%, and fully shut down again (this time making sure it was completely off). The next day, I powered it on, so it didn't drain completely, but the battery life was at 49%.

I'm going to continue experimenting, but I'm wondering, is the battery supposed to drain at all when the Air is completely shut off? And if so, is 3% drain normal?

If I have a faulty or failing battery, I'd like to know ASAP. Please chime in, or try shutting down yourselves for a day or so and report back?

I believe what you're seeing is normal, however, since the machine is still under warranty, you might want to run this by Apple and see what they say. I have an older MacBook (2008 model) which displays the same battery behavior but there are probably many more cycles on it than on yours.
