Which email setting consumes less power, push or poll?

During my experience as a Blackberry administrator and programmer I learned that any phone that used HTTP extensively (where the TCP socket is left open waiting for a response) drains the battery unnecessarily.

Somehow Blackberry was able to work around this limitation and offer devices that last several days on a charge and still be up to date on email.

After reading this information on Direct Push it seems that MSFT phones are leaving a socket open, therefore leaving the cellular radio always on in the Transmit & Receive mode.

Do Windows Mobile phones have any "magic" that makes the battery last longer when doing a TCP "long poll"... perhaps turning the radio on or off as needed for Activesync or other long-poll applications?
