WiFi can be a big battery drain, but so is the screen, and (perhaps most
importantly) the mobile aerial. The second of these is perhaps obvious,
the first and third depend on distance to the receiver since the output
signal of the phone is variable, the mobile signal much more than the
WiFi. If a phone is continually searching for a mobile base station
battery power will plummet.
I used to work for a certain Finnish mobile company. There is no if.
The mobiles need to continuously talk with their cells to handle antenna
transitions, network notifications, sms/mms protocol handling among many
many other things.
