Sorry yes, that was average power for the whole phone, a phone can transmit 
at higher powers (if you are in a very weak signal area) but only for a very 
short time period (I guess just 1 packet every minute or so to let the base 
stations in range know you are still there incase of an incoming call).  Of 
course if you are in a call average power use will be much higher, which is 
why "talk-time" is something like 8 hours and "standby time" is usually a 
week or so.
