Hey all! I have my MBA mirrored to my television in my dorm room for use as a desktop when not out and about. I've noticed that it drains battery quite faster than it normally would. I also use a bluetooth mouse and keyboard. I am sure that all of that would drain the battery quicker than normal and is normal. Although, in sleep mode I still feel that the battery depletes quicker than it should. I leave the HDMi-Thunderbolt cord plugged in when I shut the lid. Could that be it? Any ideas?

Mirroring does use more gas, but since I assume one is not lugging their big screen TV around so yer doing this at home... what's the prob?

Why not leave it plugged in when you have external devices connected?

I was just curious. I let my devices run down before charging them. I'm one of those guys that still believes you should run a device down before charging it again.

That's not necessary with Apple notebook batteries, and you shouldn't fully drain them. Run on battery whenever you need to and plug it in whenever you can. You can plug or unplug any time you need to, regardless of the charged percentage, and you never need to completely drain your battery. Just make sure you don't run on AC power exclusively, as your battery needs to be used regularly to stay healthy. The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.
