I'd be interested to hear and read about examples of this being tested in the market. Have consumers been presented with a choice between phone thinness and battery life on the otherwise same phone hardware?
http://www.wired.com/2012/04/why-is-htc-choosing-phone-thinn... > According to Kilburn, HTC’s consumer research shows people prefer thin smartphones — between 8 mm and 10 mm thick — as opposed to thicker devices with longer battery life. One data point, but that's what HTC's claiming their customer research shows, and Apple's trends suggest their internal data points the same way.
There's clearly more than the one option going into the choice here.
