Video – Apps Security: Google insists that Gmail access is thoroughly verified.
A new study found that a desktop iPhone sends data 50 times less often to Google servers than a desktop Android phone.
According to a 55-page report titled "Google Data Collection", conducted by Professor of Computer Science at Vanderbilt University, Professor Douglas C Schmidt.
The study comes as Google faces criticism and reaches a lawsuit of revelation that turns off Location History, stops tracking iPhone and Android users' location.
It is worth noting that the paper was published by Digital Content Next, a trade association supported by major news networks, including the Associated Press, Bloomberg, Financial Times, The Guardian, ESPN and ZDNets parent CBS Interactive.
The study is divided into Google advertising and roll data collection plays. However, from a user perspective, it focuses on Google's collection of passive data, such as location data, as opposed to data that a person deliberately shares with Google using Search or Map.

To compare Google's passive data collection, Schmidt creates an Android phone with Chrome active in the background, and an iPhone with Safari, but not Chrome. Both phones were standing and untouched for 24 hours.
Over this period, Schmidt found that the Android device sent 900 data samples to Google servers, 35 percent of which were location-related, while the rest was for Google Play and device data.
In total, the Android device sent about 4.4 MB per day to Google while iPhone sent 0.76 MB per day, or about six times less data than the Android phone.
Google servers sent over 40 requests per hour to the Android device compared to 0.73 requests per hour to iPhone.
The comparison also found that iPhone sends data 1
"Our experiments show that a sleeping, desktop Android phone (with Chrome active in the background) communicated placement information to Google 340 times over a 24-hour period, or an average of 14 data communications per hour," the author notes.
"In fact, placement information represented 35 percent of all data samples sent to Google. In contrast, a similar experiment showed that Google could not collect an iOS Apple device with Safari (where neither of Android or Chrome was used). some noticeable data (location or other) in the absence of user interaction with the device.
