WiFi more of a battery drain than OTA Network?

[stimulatedboredom]

Probably a dumb question, however I wonder if it is less of a battery drain to use my WiFi at home / work than to simply use the Sprint network / Ev-Do Rev A?

I figured that since it can read my WiFi easier, it might use less power, then again it is a function on the phone that needs to be launched and therefore might be draining more.

Curious if anyone knew for sure, thanks.

There are threads covering this already. The consensus seems to be that wifi is indeed better on battery life.

Edit: turn wifi off when not near a known network, like while driving. Searching for networks probably takes a good amount of juice.
