Dear, there are two cases. If you are using WiFi as well as 3G, then WiFi will consume less battery as compared to the latter one. But this is totally opposite int eh case of standby. When your mobile is on standby and both of your connectivity options are turned on, then WiFi will consume more battery as compared to 3G. So, its always suggested that turn your connectivity options Off when not in use.

WIFI consume less battery bcoz 3g,2g are the constant up and down draw with signal strength and have always heard that this will pull more from the battery over a consistent WIFI connection.

Traditionally, WiFi consumes more battery than 3G but things have moved on in 3G as well as in WiFi algorithms and implementation. In later versions of 3G, discontinuous transmission/reception and HSPA/HSPA+ helps save power. Similarly in WiFi, a lot of implementations use something like a sleep mode (cant remember the actual technical term) to help save battery. So the best way to find out how things work for your phone is by trial and error. A simple logic generally used by people is that WiFi is an additional radio that means it uses more power but that may not always be true. When WiFi is being used for data, the 3G data part is switched off and what it means is that it reduces the signalling overhead that is used to establish connection. It also helps the mobile network avoid overloading, so if you can, use WiFi and it always helps. Finally, in case you are relying on your 3G connection, it uses your data allowance (unless you are on a true 'unlimited' package), depending on the network usage your speeds may not be great and if your reception is not great then there may be retransmissions of packets that can affect your battery life seriously. So in summary, there is no easy answer but trial and error works best.

As per my view WiFi consumes less battery than 3g in working condition but when in standby 3g consumes less battery than WiFi
