In a year of using ActiveSync for an actual Exchange server connection, I can say with certainty that if you don't have a connection to an Exchange server, ActiveSync doesn't do jack squat until you connect to the PC for a sync. Not to mention, disabling it can potentially break your ability to sync with the PC.

While I'm not discouraging you from disabling it if you see fit to do so, there is really not much point in doing so, and you'd have to really provide some solid evidence to prove that it's misbehaving so badly that it's draining a battery with no connection configured.

If you want to look at things draining the battery through a data connection, look at the Weather tab, and the actual email account sync settings you have setup. Turn off beams. And adjust your power settings so your display isn't at full brightness all the time... etc.
