In general, higher temp=higher resistance=more power needed to drive the circuit. This is why superconductors need to operate at very low temps. Unless there is something I'm not seeing, I can live with the heat and would choose to go without the shield.

Thank you again.
The heat shield he is describing is not one to protect YOU from the heat, it is meant to isolate the radio chipset from the battery compartment.

A cooler battery will discharge slower. ALSO, the battery has a protection circuit - once it hits a threshold temp it will not allow charging until it cools. 41*C or so I think.

*edit*

Reading back now, I am a little backwards with my logic. Yes, the heat shield is designed to absorb heat that generally passes through the button pad - but as a result should also have an effect on the overall operating temperature of the device. Anything installed that will potentially wick heat away from the battery will impact the charge lifetime.
