Over at whenwillapple.com I found this graph showing how long it will take to charge an empty iPhone 4 to 100%. Via the USB port it took roughly 160 minutes and through the standard outlet charger it took only 120 minutes. Quite a big difference, so if you’re in a hurry be sure to use the outlet instead of the USB.
