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.

I think you are grossly uninformed/misinformed
First of all, the benefits of Exchange are that it can sync contacts & calendar as well. This solution only syncs up e-mail... kind of useless.
There is only one provider out there that can do true Push and that is RIM through Blackberry. They have the patents at the carrier level where the tower will physically notify the device when there is stuff to receive. The device doesn't "check in" for new data.
Since nobody else can do this, the other players came up with various ways to try and do the same, but with big drawbacks.
IMAP IDLE basically keeps a connection open all the time in IDLE mode until the server notifies the client that new mail has arrived. Although the client doesn't check every X minutes, the connection is still open and it drains the battery.
Exchange Account / Google Sync ( Activesync ) does the same exact thing. It keeps a connection open at all times thus also draining the battery.
Conclusion: Get a Blackberry if you are serious about e-mail. I hear version 10 will rock.
Otherwise, just use IMAP IDLE. Makes no sense to configure z-push only for e-mails, without contacts & calendars.
