It does drain the battery.  On the Android there is a nice utility
that reads your phone logs and prints out a nice shiny pie chart of
what used your battery today.

Mine is:
55% display light
17% cellular network
22% wifi network
6% cpu

Numbers are approximate as I interpreted the readout liberally.  I was
doing a lot of WiFi web browsing in a bad cellular area.
