WiFi battery.

[NastyNeil]

I just checked my usage and the thing that seemed to be using the most battery is my wifi at 20% Is that right? I thought wifi was supposed to help save battery.

Yeah, that sounds normal. It is basically telling you that the phone is doing exactly what you expect the phone to do... use wifi for data whenever possible, rather than the cell network. Remember, the amount of power being used by the display is not being reported there, which is the big power user on your phone.
