No, not really, but the idea is keeping ur phone docked/charged can generate extra heat. Whether or not that heat will lower the long term life of the battery is still controversial in my opinion, so for me just set the thermostat to a lower tempertature. It's good for getting to sleep quicker too.

On a different note, I also think that extended batteries are good in 2 things:

1. Increased mAH
2. Less charging frequency. So charging an extended battery once every two days is better than charging a standard battery multiple times a day or even just once a day.

That's why as soon as HTC/Sprint release an extended battery for the Touch Pro. I'm getting it!
