    Obviously, heat will hurt the battery life and the cases, plastic, rubber, silicon etc, will trap the heat, especially when charging.

    Is this the case?

    No! :) The 'phone shouldn't get warm whilst charging.

    why would heat PER SE hurt the battery life?

    the heat is energy lost due to the CPU running really hot during complex processing tasks, due to the LED backlight running at high intensity and for a long duration

    i would think heat is merely a symptom of increased consumption and whether you 'trap' it, doesn't matter for the battery life, really
    That the phone could overheat and be damaged, that's a different story

    Heat is the enemy of all things electronic. While individual components are all designed to withstand varying degrees of heat, the cooler a device can be kept, the longer it's life will be. In the case of the captive battery, heat is it's worst enemy.*

    I take my iPhone 3G out of it's case (either a Griffin Wave or an iPod Sock) when charging and I plan to do the same with the iPhone 4. Why risk it?
