Cerberus @Mr.ShinyandNew安宇 I believe 3G uses significantly more power to stay connected than Wifi, perhaps twice as much even? But I think it is still very little under normal cirumstances, so the difference won't make that much of a difference compared to what other things there are that drain your battery. It's just an optimization thing. However, when you have bad 3G reception, that's a different story.
