How Often Do Smartphones ‘Phone Home’?

The results are pretty clear: even when not used, Android phones send information to Google around 40 times per hour, compared to just 4 times iPhones send info to Apple’s servers. During normal use, that total rises to 90 information requests per hour for Android phones compared to 18 for iPhones. Interestingly Google even collects more data from iPhone users than Apple itself does. This however, only works when the phone is used. In idle mode iPhones very rarely communicate with Google’s servers.
