Ok I'm asking this in regards to my battery life. There is a 3G icon at the top. Next to it has an up and down arrow. Next to that is the bars. I'm new to all this because I've never had a smartphone so no flaming, lol. Sometimes the 3G icon will go from lit up to dark. Does that mean it is connected, gets disconnected and tries to find a signal again? And sometimes one the arrows are lit up and the other isn't, sometimes they both are lit and sometimes neither. Is this something to do with data being downloaded and uploaded by the phone through the network? Thanks.
