On OSX there are a ton on Apple services phoning home for all sorts of reasons, all the time. Try installing Little Snitch some time and be amazed. And I wouldn't be surprised to see the same on the iOS devices. Any Apple device is super noisy on the network with just mDNSResponder alone. Most of them are also for useful features, it's just that they are all talking over the wire and potentially exfiltrating user information. I don't think that people realize how much data is sent around all of the time. Here is a non-exchaustive list just to give an idea: * locationd -> gs-loc.apple.com:443 * apsd -> .push.apple.com:80,443,5223 * mapspushd -> .ls.apple.com:80 * UserEventAgent -> :80 * ntpd -> time.apple.com * ocspd -> :80,443 * ... I didn't put all services. Notice that some data is not even encrypted.
