There have been quite a lot of suggestions regarding this on mailing list, try searching the Archives. My advice would be: 1. Disable Push and use Fetch as email retrieval method (every 15 min). This should improve your battery life dramatically 2. There has been someone on mailing list mentioning that if there is another device behind the same NAT taking to your IMAP server (e.g. Thunderbird) at the the same time as your EAS client it’ll fool the server into the endless loop (some can confirm this?) 3. Don’t use EAS on iOS. Since iOS has built in IMAP, CalDAV and CardDAV support I see no reason to use EAS at all (other then ease of initial configuration). You can achieve the same results with separate mail, calendar and contacts account, EAS on iOS does not bring any advantage over that (quite the opposite).
