I removed and re-added my Google calender account and my battery life just about doubled!

Stange but trueo. I'm starting to wonder if using the Data Transfer Assistant really screws up the data on the Pre or Synergy and makes battery life way worse for some reason. Now I am going through all the account DTA touched and re-setting them up.

Maybe a poll - who has poor battery life and used DTA? Who didn't use DTA and is having great battery life?
