Wi-Fi vs. 4G

[jrmarinojr]

When you turn on the Wi-Fi it seems to turn off the 4G. Is this true??? If so, it could save a ton of battery!

Yes it does on both questions.

for some reason when my wifi is on i still see the 4g or 3g up on the top banner there with the up and down arrows. isnt that supposed to be gone once i enable wifi?

You still need the 3/4g for voice calls.

So then from a battery sparing standpoint would it make sense to just leave Wi-Fi on all the time regardless of if you are able to obtain a signal?

Doesn't voice go over the 1X protocol?

Yes and 4g should shut off on wifi. If not shut it off manually with the network widget.

My understanding is yes. When WiFi sleeps then the 3G/4G will come on to do work(non-voice work) but when you're on WiFi then those radios shut off and you save battery. WiFi is much more battery efficient than 3G/4G.

You might have your wifi on but your not connected if your still seeing 3g/4g in the notification bar. Go in settings and wireless connections and in wifi settings you can choose what network to connect too.
