Increasing power to stay connected: Within IS-95 this is not, in general, allowed. The whole purpose of the much talked about power control is to prevent this very scenario. No user is allowed to be transmitting such that the receiver is getting more power from them than from the other users. Having said that, excess power transmission capability could be useful under some of the conditions given by Maurice. For instance, if there is only one cell and a fixed amount of background noise then the users who could transmit more power would be able to stay in contact further out than the lesser powered users. And in the area of speculation - real knowledge requires models which I do not have access to - it is possible that it makes a difference if there is a failure mode for a CDMAOne cell system where the cells shrink away from one another due to too many users in neighboring cells causing noise (just as the conversations that you are not listening to at a party are noise), then the overpowered phones will be able to communicate further into the dead zones between cells. In the process they (these overpowered phones in aggragate)further increase the noise floor for users in other cells and enlarge the dead zones. But this cannot happen unless the system is first overloaded to such a degree that the cells develop dead zones - i.e. disparity in power transmission cannot cause a capacity problem but it may aggravate one. Clark PS Putting bigger batteries (e.g. D instead of AAA) in a phone will extend it's battery life, but not it's power output. First, all the batteries you mentioned have the same voltage (like water pressure). For this you should be grateful since a battery with a significantly higher voltage would just fry your phone. Second, in any case it is the electronics that determine the maximum power output. A good analogy is a car engine. Putting in significantly more energetic fuel will not make you car more powerful - in all likelihood your engine will self-destruct or just not function. To get more power you need to redesign the engine.
