Sorry if this has been posted before but I just got the 13" Macbook Air and my battery life calculation is always at around 3-4 hours after being fully charged then other times its at 6 and half hours. I have an iMac and this is my first foray into Apples laptops since the PPC powerbooks. How can I minimize battery drainage the best? I have bluetooth turned off Im surprised it was turned on automatically. Also here are some spy mouse codes from Starbucks! Thanks again in advanced!
