WiFi usage/ blocking devices

Certain devices like iPhones have a privacy setting in WiFi that literally randomized MAC address.  This is not needed on a personally owned home network and I turn it off in this case.  Furthermore these mobile devices do a lot of background work in default mode, so that could be a source of data usage.  Just throwing it out there, but something I would investigate. 

Is it a BGW210? Where is this notice showing?
