Hey, I just got a 13'' black macbook, finally made the switch, and I'm trying to figure out if my battery is normal. I did the whole calibration thing yesterday and today on a full charge my battery lasted around 2:45. I was doing some intensive stuff though (importing a full ipod, things like that), the battery drained to 0 and it took just over 4 hours to fully charge. It was sleeping for pretty much the entire time. So basically how long should it take to charge the macbook from 0 to 100%? and on average use (medium brightness, browsing the net type deal) how long should that charge last?
