There are a lot of variables involved in everyday usage. Is not really an objective method for measuring battery life.
When tests are conducted. Each phone is given similar settings that would effect battery life (bluetooth, WiFi, screen brightness) and are given the same repetitive action until the battery drains out. This is the most unbiased way to accurately determine battery life.

E71 - End of the working day and beyond
N95-8GB - between 1-2pm
iPhone 3G - 11:30-12:30pm.
I've been using the iPhone for 2 months now, and it consistently lasts for less time than the 2 Nokia devices I have/had before it.
When you squeeze more functionality into the phone. You either have to make a chunkier phone or reduce the size of the battery. As I said compromise has to be made somewhere.

I'm just giving you a general flavour of the iPhone battery life in comparison to theses other phones. Personally I feel the iPhone would do a lot better if the backlight would dim and thengo out completely after a period of inactivity as opposed to staying permanently illuminated even when you're not using it.

It might be a good point. And I'm personally with those who vote for chunkier but longer-lasting phone...
Yet, battery dimensions appear to be not critical argument...
Dare I speculate a bit? The words "underclocked to ..." suggest me conclusion Apple were lamed by their battery supplier. They designed a bright product never seen before having been promised the monster battery in it. At the end, they found themselves with only regrets of that guy. There came rescue measures like undercloking the main processor, delaying 3g, etc...
All things considered, I think it wise to assume that as the mobile market becomes saturated with more powerful devices (iPhone, etc.), we will see the dependance on the home desktop wane. Most of the folks I network with rarely have the time to sit at a desk at home to "surf" or chat, when they can already do these things on their iPhone on the move. More memory, better battery life, faster processors will always become reality making the unimaginable possible. Just think 5 years ahead....the mobile phone or tablet WILL be what most people use for most of their social, computing needs.
I predict that Apple will realize this and adjust their desktop/laptop offerings accordingly.
If push email is supported in the 2009 iPhone, will the OS software be available to download on the iPhone 3G?
Or, to put the question more generally, when Apple issue software updates, (e.g. OS 2.2) are they download-able on all iPhone models or only the most recently released?

N95-8GB and E71 easily outlast the Iphone 3G
Can you post a review that supports your opinion, I haven't found any review anywhere that supports this claim.
It's not a review, it's my everyday usage.

You give up some battery life for a faster processor, faster data connection, larger brighter screen.

Look, this is E61's battery (Lithium ion 3.7V 1500mAh rechargeable battery; Size: 65x43x5mm), close-up:
This is iphone's one (1150/1400mAH):
iPhone's battery is bigger.
