The iPhone X continues to be Apple’s top-selling smartphone according to the company’s latest quarterly financial results.

In its second-quarter 2018 results, Apple reported revenue from its phone business was up by 14%, even with just a 3% increase in unit sales. Although Apple doesn’t break down how many of each of its phone models it sells, it’s clear that the company is seeing this increase in revenue by selling more expensive handsets.
