Mine charges all the way up to full from below 10% in an hour and a half.
This is when I'm completely shutting down the OS X, and charging it.
I was very surprised.
Yeah, mine is actually way faster on the chargeup (haven't timed it "officially"). The estimation gave me 3:04, but it was about half that when it got to 100%.
From 3% - 100%, an astounding 1hr 48 min. Absolutely incredible, considering I was running VMWare half the time, and had music playing in the background.
