I had this problem with my Gmail account after I installed 1.2. My notifications were coming in immediately, and it was saying "last updated 1 minute ago" and all, but the constant syncing drained my battery within 3 hours. I deleted and re-added and the syncing arrow wasn't around anymore, so that stopped the battery drain. Unfortunately, after I did that, my emails aren't updating at all. I have to manually update, no more push notification. That's the problem with both my gmail and MFE (which is my work email). I tried deleting the accounts a few times and even rebooting after deleting and re-adding. Nothing seems to be working. Getting very frustrated.
