Which Android phones offer the longest battery life?

Simple answer = None.

If you want battery you'll need to get a Blackberry, battery life
on
Android phones ranges between totally unacceptable and even worse.

You can survive with a spare battery and a charging dock.

It might be useful to specify the number of hours or minutes of
talk
time, and the same for idle time. What is "totally unacceptable"
is
likely to vary from person to person.

Sweet Lord, Richard, we're discussing smartphones. The impact of voice
calls on smartphone battery life is inconsequential next to the display,
data connection, and background progress ( fetching email, etc.)

Smartphones these days pretty much come in two flavors: those that can
make it through a day without needing a recharge, and those that can't.

I was going to say the same thing, but in a nicer way. :)

My understanding is that the cellular radio uses less juice than, for
example, the screen (a primary consumer of power) and the data radio(s).
"Talk-time" might be a good indicator of how long the battery would last IF
YOU WERE DOING NOTHING ELSE WITH THE PHONE, but that's not how people use
smartphones these days. Most talk-time ratings are in the hundreds of
minutes (hours and hours), and that would last most people through an entire
day. Browse/email/Internet times are far less, and often chew up the
battery in short order.

Here's an example off the Apple website for the iPhone 4S. These numbers
don't reflect reality, given the current Batterygate problem, but it gives
you a relative sense of what consumes battery life:

* Talk time: Up to 8 hours on 3G, up to 14 hours on 2G (GSM)
* Standby time: Up to 200 hours
* Internet use: Up to 6 hours on 3G, up to 9 hours on Wi-Fi

So, that particular phone lasts more than twice as long just talking using
the GSM voice radio than it does surfing using the 3G data radio (and I
wonder if the 6 hours even considers screen and processor use. Doubtful.
So, talk-time is probably more like 4X real-world browse time...)
