Which drains battery faster? Tmobile 4g or wifi?

4G for sure. My other phone had 3G and that battery was drained pretty quick (it also got very hot).
 
4g but I don't believe this has been tested yet. Of course, wifi isn't exactly a battery saver either haha.

I doubt there's much testing data out there. However, 3G does eat battery faster than WiFi. It's fairly safe to assume that 4G doesn't use less power.
 
wifi will always be more efficient than any tower broadcast. Less power needed to send/receive. In general, your range of connectivity will correlate to the power needed to communicate.

Bluetooth uses less power than wifi, for example (short range). GPS uses the most power (outer space range).

I agree with that mostly, however, as far as the phone is concerned, its just receiving "space data" not sending. Ya the satellites take a lot of power, but I'm pretty sure the 4g antenna takes a lot more than having GPS on.
 
Wifi even uses less power than 3G because 3G has to send out a much stronger signal to reach the tower.
