Most of the UMTS devices I've looked at have better battery life when transmitting vs GSM (talk time), but shorter standby time.

The way I understand it is that you get better talk time, not sure about standby time, but data transfers eat battery a lot heavier than EDGE does (by a factor of about 100-115% by my estimates with my Kaiser).

I leave mine on EDGE 90% of the time because I like to have online email and IM, and with 3G enabled my battery life is less than 16 hours. It's 36 hours on EDGE. However, on EDGE the data connections get dropped during a voice call, so that and the obvious speed difference makes it difficult to decide to force the phone to EDGE or just to charge more often.
