If you're polling, then that alone will chew through far more battery 
life than living with the presence updates. Well, not strictly true, 
but each HTTP poll would have to cost less than the octets sent in 
TCP ACKs, which would imply a vast number of presence updates between 
each poll.

If that's the problem, then the user has too many friends. ;-)
