Apple's latest iPhone models are attracting more Android users to the brand than in previous years, a new report by Consumer Intelligence Research Partners (CIRP) found. Signs have pointed to relatively weak demand overall for the iPhone X, XS and XR, like lowered guidance by some of its key suppliers and Apple's announcement that it will no longer disclose unit sales for the iPhone.

The report found that 16 percent of iPhone buyers upgraded from an Android phone in the 30 day period after the launch of the iPhone XR. After the iPhone 8 and 8s were released in Sept. 2017, 12 percent of iPhone buyers upgraded from an Android phone, and when the iPhone X was released in Nov. 2017, that number was 11 percent.
