I cannt comment on the battery life issue, but the problem is with IP fragmentation.
tcp's better battery life may be related to the fact that if the phone is behind nat, the phone itself will keepthe nat binding open by sending every 20 MINUTES or so a keepalive message to the proxy.
Does NAT devices keep TCP bindings open for 20 minutes if there is no traffic?
regards klaus
if you use udp, proxy must nat ping the phone from the proxy once at about 20 SECONDS.
