Max Battery life. Push or fetch?

[mybluesky]

In an effort to maximize battery life I'm trying to decide whether to use push or fetch.
Does push constantly check for new mail every second? or is it simply just when a new email arrives in your inbox it is pushed to your iphone (using imap gmail)? if that is the case it may be more battery efficient than fetch.
if you have any more extensive knowledge on these two features please share because my knowledge is limited to what gizmodo posted about maximizing battery life.

My gut instinct is that it probably depends on how much email you get!

If you don't get many messages, use Push and they'll trickle in one by one.

If you get loads, use Fetch and set it to download every hour or so.

And, whether you can wait for it to come in, or if you just have to check every 5 minutes!

Fetch will realistically only save you if you don't check (fetch) very often. If you're the type (and we all are, at some time or another) that just has to check every 5 mins instead of just waiting, then you're not saving anything...

If you get lots of e-mails, then maybe an hourly automatic fetch is better, but if you get few, then the push might be best.

I was under the impression that it also depends on your email provider and if they support Push. I don't think that either of mine do, so I set it to Fetch. Otherwise I'd be waiting all day and not get any email.
