I know battery life is a consideration in what to add or not add to iPhone 5. Given that both 4G and dual core eat battery, which would you think is more important to have in the iphone 5?

Given the new tethering options, I'm committed to getting a 4G phone for my iPad and laptop. Wanted to know what other users are thinking.

Dual core is supposed to save battery..?

I'd bet on dual-core over "4G" easily.

4G isn't widely available yet, plus I'm sure AT&T will screw the hell outta iPhone users on 4G plans. Dual-core improves battery life, not hurts it.

Pay attention to the last 2 paragraphs.

It's going to be dual core and there will not be any 4G. It might have HSPA+ which some are calling 4G (AT&T and Tmobile) but that is still 3G. The chances of it having LTE are slim to none.

Well for one it's a smaller manufacturing process, making it draw less power. It is able to turn off a core and throttle speed based upon usage. They also optimize battery manufacturing processes.

Think about it. Laptops today are smaller, faster and even quad core at times. And yet battery life has improved....
