All of the phones listed above the Apple iPhone 4 on the "3G Talk Time Battery Life" don't actually do 3G calling. Those phones revert to 1X technology for phone calls, conserving battery life and disabling 3G data services while in a phone call.

Funny how they didn't put even one real phone on the list.

It would have been nice to see some more statistics based on the amount of screen real estate, at least for the web surfing data. The data itself isn't really fair to show without some indication of this.

I was bored, so I just crunched up some numbers using the aspect ratio and the diagonal screen widths. Comparing the EVO to the Iphone, the EVO has about 34% more screen real estate to light up. This actually shows pretty nicely with the wifi testing, the Iphone does ~30% better because it has 30% less screen to light up. But looking at its use of 3g, the Iphone still performs better, even after having accounted for the smaller screen battery benefit.

The true winner by farrrrr? The streak. The battery life on that thing's a freak.

I plan on getting the Focus and using BLACK as much as possible : ) As long as I can get through the day I would be happy. You would think a new OS would at least match the Iphone for battery life though.Can always buy spare batteries for trips.

They should also list the performance of the browser too. If the browser runs twice as fast, then you're probably going to view considerably more websites even if the battery life lasts twice as long.

The (now) one year old Nexus One HALVES the rendering time of Javascript benchmark (Sunspider). Imagine newer Android phones with better GPUs and / or more efficient GPUs.

Granted, even if it reaches 1/2 the time in a benchmark, you're not going to get twice the browsing done -- BUT it does decrease the time spent waiting, and IMHO better, as I want things render as fast as it can so I get get what I want to get and move on (especially if I'm with people).

If I need more juice, I'm just going to bring:
1) a tablet with a USB port (ADAM FTW!) or an emergency charger
2) a spare battery
