Re: The iPhone thread
Iphone 4 has a 1,420 maH battery
4s has a 1,432 one

Neither are terribly big, although the thing only has a smallish 3.5 inch screen to drive

WiFi usage at home is much preferred over 3G as it will use a lot less power (if you are using WiFi why not turn off 3G at that point)

Simply because the transmitting power of WiFi is usually smaller than that of a 3G radio since the access point is much closer and the signal will be much stronger than the usual 3G tower. They tend to be less dense than 2G towers and the phone will need to transmit with more power in order to keep reasonable signal strength with 3G.
