I've used Gmail via Exchange on my iOS 5 iPhone 4 for a while now.
Recently, I upgraded to an iPhone 4S.

However, I noticed that now, after I setup Exchange battery drain increases significantly (from 0.5% drain for 1 hour idle to 2-3% per hour).

Setting up Gmail via the imap (default Gmail access) works better for battery. However, I can't live without push email, and I don't see any reason I should do without a feature I've come to enjoy for a number of years.

I think you answered your own question, you said you can't live without it.

I have 4 push email services set up and i did try and live with fetch for a day, i couldn't and honestly the difference in battery life was quite minor. If you just keep it plugged in whenever you can then you will always have a decent charge left.

On the occasion i let it run dry i do seem to get about 5hr's 30mins of 3G usage and nearly 2 days of standby. 1 Day if i don't use airplane mode overnight.

If i use the music player i get in excess of 6 hours.

All things being fair, that is very close to the official figures and i'm combining standby with usage too.

Then decide what's more important to you and take that route. Doesn't seem particularly difficult to me.
It's a compromise I'd rather not take. I'm just not used to the idea of a new product being inferior to its replacement

It's not inferior. It just works differently. You get real-time access to mail at the expense of slightly more battery use (because it has to be ready to accept the new mail). It's like saying a sports car is inferior to a regular car because it uses more gas, if you want efficiency go the efficient route and live without the speed.

You can set exchange to be fetch and not push if you want.

I'm not complaining about push email draining battery. I'm completely fine with that. I'm just trying to make battery life with push email on iPhone 4S the same as my old iPhone 4. enabling exchange seems to have significantly decreased battery life in iPhone 4S compared to iPhone 4 (also with exchanged enabled).

Hopefully apple will fix this issue in the next update. Probably the phone is powering on both cores when checking mail and thus using a lot more power. It could be as simple as the cores in the A5 powering on at full speed before throttling back, although that would mean a hardware issue and Apple don't usually update that firmware.

I found that turning off calendar in the notification menu increased my battery life. I think a bug exists for exchange calendar.

A battery drain of 2-3% per hour?

At that rate your battery will run dead in...50 hours or so? How long do you want your phone battery to last for?!

People need to quit worrying about their battery life so much, checking your phone every 10mins to see how much the battery has drained probably isn't helping either.

No hate, I just don't really see 2-3% being that big of an issue.

Unfortunately, I do see 17 hrs STANDBY time as a problem.
