Network derived location does not represent a meaningful extra power draw. GPS involves a separate radio system (rx only, admittedly) and is only active when so

  Interesting re: the GPS usage, thank you. I would have thought that the process of repeatedly acquiring the satellites and establishing the fix on demand would have been quite an overhead, though. /me goes to read more Network location does require wifi to be permanently active, which for some reason seems to be a magnitude more power-hungry than 3G. So most folk I know turn-off wifi when not interactively using it.
