Hi jltung, I do understand that powering up GPS, WiFi, and Bluetooth hardware, that battery life will decrease. And even more so if the Bluetooth "connects" to something. But GPS is looking to satellites, and WiFi for WiFi networks, and Bluetooth for other Bluetooth devices. None of those come over the 3G network, so I still don't understand how a good 3G signal helps. But that's OK. By the way, I now have 70% battery left after today, after a full charge last night! I think I can live with that. Eric Edit 12/4: After thinking about the impact of 3G reception, I think what happens is that if the coverage is bad, the phone keeps transmitting to search for towers, and that would certainly impact batter life. Even a "dumb" phone would chew up batteries if in a poor (or no) reception area. It just keeps trying.
