New statistics were published today by Consumer Intelligence Research Partners (CIRP) covering Apple's fiscal quarter that ended September28,2019. CIRP found that the new iPhone 11 and 11 Pro/Pro Max models accounted for 20% of US iPhone sales with only two weeks of availability at the end of Apple’s fourth fiscal quarter.

Apple's iPhone XR accounted for 36% of US iPhone sales during the quarter as the chart below proves out.

Josh Lowitz, CIRP Partner and Co-Founder: "iPhone 11 represented half of the sales of the three newly launched iPhone models. Combined with iPhone XR, which was similarly positioned in the line-up and shares many of the same features, these two models account for almost half of US iPhone sales in the quarter.

The premium priced iPhone 11 Pro and Pro Max models together only represented 10% of sales, and 21% when combined with similarly positioned and recently discontinued iPhone XS and XS Max."  

It seems that iPhone customers have a greater appetite for the historic flagship priced phone, with fewer paying up for the new top-of-the-line models.”
