I read in the batter guide thread the statement that heavy browsing using 3g is better on battery life than edge. The theory was that you can view more pages with 3g than with edge and therefore it is more economical to use that mode. I wanted to open this up to debate in it's own thread because I think there is more at play than just how fast the pages load. This is especially important to a person such as myself seeing as most of the time all I do is surf while at work and have excellent edge and 3g coverage. Wouldn't the 3g antenna alone being switched on and searching for a signal combined with the brwsing would drain the battery faster than edge surfing, wouldn't it?
