When considering buying a smartphone, we not only resort to base our decision on iOS or Android OS but consider that the bigger the phone, the better it is. Thus, one of the major factors we drool upon is the screen size. But there turns out to be a correlation between the square inches of your screen and the amount of data you end up using on your smartphone.
American multinational software company Citrix reports a finding that users of the 5.5-inch iPhone 6 Plus consume twice as much data as those with the smaller 4.7-inch iPhone 6.
Another study was conducted by Open Signal for Android smartphone users where data usage statistics were collected for usage over a cellular connection and Wi-Fi on the same day.

The above graph suggests a weak correlation (with a Pearson coefficient of 0.21) between screen size and data use over a cellular connection. What this suggests it that people broadly use their cell phones in the same way when on the move, as there is only a weak relationship between screen size and increased data use.
Whereas a similar graph was plotted for data usage over Wi-Fi for different android smartphones.

As evident from the above graph, in case of data usage via Wi-Fi, a significant correlation (with a Pearson coefficient of 0.55) between screen size and data use over Wi-Fi. As screen sizes get bigger, people consume considerably more data.
Hence, while additional square inch of screen area leads to 75MB of extra data downloaded per month over a cellular connection, each additional square inch of screen area leads to 288MB of extra data downloaded per month over Wi-Fi
With increase in smartphone usage and availability of even faster networks (4G), live video streaming is on the rise. A larger screen leads to experiencing videos even better, more streaming and thus increased data usage. For example, “iPhone 6 Plus subscribers generate the most data volume, double that of an iPhone 6. This increase impacts subscribers when choosing a new device — be careful to select a data plan that matches your supersized screen,” the report read.
