I have found out that if I go into the back of my office building for any length of time my Treo 700P becomes warm! I have very poor cell phone reception in this part of the building. It is a block building with a metal roof.
One of the features of a cell phone is the power conservation. If there is a strong signal the output power is reduced to save battery power. Of course if the signal is weak the transmitter is turned up to full power. If the phone is in a weak signal area for a long time period of course you will see a shorter battery life. I had noticed this with another phone but had not given it much thought until I found my Treo warm! Leland Cox
