I'm a first time Mac owner and got the 13" base MBA. I plugged in the machine and let it charge to full capacity, the first time I used it. Am I supposed to fully discharge the battery to calibrate it? Apple says on its website that there is no need to calibrate newer batteries. So, I shouldn't have to fully discharge the battery after the first full-charge? I just want to make sure that I take all the necessary steps with a new battery in order to maximize the battery life. Thanks in advance!
