My battery was lasting no longer than 10 hours on Standby after upgrading to v3.0. This is how I fixed it:
Settings > Mail, Contacts, Calendars > Fetch New Data
Changed Push to Off
Changed Fetch to Manually
Settings > Mail, Contacts, Calendars > Fetch New Data > Advanced
Changed all to Manual
Like magic. When I was on the phone with the Applehead, he asked me if it was possible that my battery was simply degrading, but the difference with Push on vs off was 10h vs 36h on standby. Insane. You have to *really* want push to put up with that.
