I have a treo 700wx. I have it configured to automatically check for and download messages from my Groupwise work email account every 15 minutes. Frequently when it checks for messges (not all the time, though) the device spends up to 5 minutes checking a few hundred "headers". This happens even when there are no new messages to download. Is there a way for the treo to check for email messages without also checking all these headers which, throughout the course of a day kills my battery?
