Hey!
What consumes more power on iPad/iPhone - 3G or Wi-Fi? Ceteris paribus ...
More interested in practical observations, but the theory does not hurt. :)

With a fairly good coverage of your city with a 3G network (4-5 bars constantly), it is preferable to use it instead of EDGE, since EDGE consumes an average of 30% more than 3G (300 mA vs. 210 mA) and is comparable to Wi-Fi consumption (up to 330 mA) (data are given for reliable reception of both networks at full load - downloading a file for example). In addition, lower total energy consumption is obtained due to the shorter time of using the 3G network due to the higher data transfer rate. If the 3G coverage is not stable, and in some places is completely absent (the situation in Moscow at the moment), it would be better to disable the use of the 3G network, since when you are in the 2G zone, your device will constantly scan the extra frequency range for 3G, spending additional precious energy .
