If I have 3G enabled, but am getting no 3G signal, does it still eat up my battery life?
 
I would think so. I imagine the phone is constantly searching for the 3G signal even if it can only find EDGE.
 
mmm. batter life.

This is my thought. I always turn it off when I'm at work as I have no 3G signal there. I'm certain it wastes power looking for it all day, so tell it not to look.

Same thing with Wi-Fi. I only turn it on when I know there's a network there to use.

Turning 3G off and using Wifi.
 
What would save more battery life: using 3G and turning WiFi off, or turning 3G off and using WiFi?

Technically I think Wi-Fi uses the most power.

But I use whatever's faster. I didn't spend money on this phone to sit around and wait. I'll use the fastest connection available and enjoy life.

I only worry about this kind of thing if I'm going to be out side all day. And in that case, there's probably no wi-fi to choose from anyway.

If there's wi-fi, there's probably a plug somewhere. The phone charges halfway in about 30 minutes. I get through most of the day and then charge the hour before I go out.
 
Well Wifi is easiest on the battery when surfing the web. So it doesn't appear that it's using the most power.
