> The end result is more accurate output, at the expense of battery life. Do you have sources? GPS is passive, yes, but the signal is very weak and several orders of magnitude below the noise threshold. Keeping receiver circuits enabled for a long time costs battery power as well. WiFi information can be obtained entirely passively as well, as AP's transmit their info regularly. I think the difference rather comes from lots of bloaty background services on Android.
