How Much Energy Does an Apple iPhone Use?

The iPhone has been a success worldwide, with the recent launch of the iPhone 3G, but, just how much energy does it use.

iPhone 3G - 4 to 6W
iPhone 2G - 4 to 6W

This was from an Apple charger, whilst charging the battery, notably when we tested the Apple iBook G4, we connected the iPhone via USB, and this drew for a short term, extra power around 12W, but after applications which launched due to connection, this fell to approximately 4 to 6W.
