Yes. By default, WiFi is enabled on cell phones, so unless you turn this capability off, your WiFi processor will continue to send out wireless radio frequency (RF) signals in search of a WiFi router. This means even if you are not connected, your phone is emitting radiation in its search to connect to a router. When you are connected, your phone is still emitting radiation to maintain the signal, by sending constant pings to the router and back. We advise turning off your WiFi processor in settings when you are not actively searching for a WiFi signal.
