Taken from Apple website. Do some of you guys exprience otherwise? For me battery drains at least 20% if I put it to sleep for 6+ hours. I'm running OSX 10.8.2 and my MBA is not even a week old. Now I've searched online and the general consensus is that its the power nap feature, but I've set that up only if its plugged in... Anyone have a clue? It's annoying when this is one of the main features that make up the Air and it doesn't even work.
