The survey found that the iPhone 8 made up 23 percent of iPhone sales this quarter, while the iPhone 8 Plus made up 21 percent. The iPhone X trailed at 16 percent, down from 20 percent the previous quarter.  >The CIRP survey states that iPhone X sales have declined since last quarter, while iPhone 8 and iPhone 8 Plus sales have gone up. 500 people is a fairly small sample size, so take the findings with a grain of salt.
