If so, then how could the battery problem be a software issue? The vast majority of the complaints regarding poor battery life are on the 4s, particularly when compared to the 4. Doesn't this immediately rule out software? Sorry I'm just trying to figure this out and I don't have long to exchange my 4s for a 4. I don't really care about Siri or the camera nearly as much as the battery, I'm not sure why anyone does. The only thing I can think would cause it is the dual core processor.
