Wifi- and turning off recording and motion?

I recently got another ring Doorbell. its an older one. If I disable recording and motion does that still eat up my wifi? I want to use my extra as a back up battery. So when my main one goes dead in about a month , i can just re enable the recording and motion on my back up and clip it in the bracket on the door. any Idea about this. I think it nuts there is no power button on ring or a toggle to turn off the wifi.
