honestly, push email has nothing to do with imap. Once the server receives it, you receive it (+/- 5 seconds). With imap, you are restricted to fetch, which I had configured for every 30 mins. This way, the battery life is far better, since the phone doesn't have to fire up a 3G connection to fetch email.

Been running it for about 5 days now and the phone life during the day before would run from 100% to ~50ish% with no other activity. Now it rests around 85-90% if I don't do any other activity.
