There are now more than 100 million iPhones in use in the United States, according to a new report. Apple surpassed the 100 million mark at the end of September, with its most popular models being the iPhone 6 and iPhone 6s.
Consumer Intelligence Research Partners (CIRP) put together the report by analyzing data on iPhone buyers — including the model they chose — then overlaying Apple’s sales data, the company explains. It estimates that the iPhone user base grew on average 8% per quarter over the past eight quarters.
As a result, around 101 million iPhones are now in use, and the latest crop of devices are the most popular.
“The analysis shows the continued strength of the iPhone 6 and 6 Plus, now one year old,” said Mike Levin, Partner and Co-Founder of CIRP. “We estimate a combined 60 million of these flagship phones sold in the US from the September 2014 launch through September 30, 2015.”
In comparison, the iPhone 5s sold just 28 million units during the same period in 2013-2014, CIRP says, while the new iPhone 6s and iPhone 6s Plus reached 4 million in sales during launch weekend along in the United States.
However, despite reaching over 100 million active users, the growth of the iPhone user base has slowed, according to CIRP co-founder Josh Lowitz.
“In previous quarters, we saw the installed base grow by as much as 17%, in the December 2013 quarter after the launch of the iPhone 5S and 5C. As the US market matures, Apple has fewer first- time smartphone buyers to add to their base, and faces the challenge of attracting loyal Android users.”
After the iPhone 6 and iPhone 6s series, the iPhone 5s is the most popular device, following by the iPhone 5c. The iPhone 5’s user base is quickly diminishing now, but it’s still large enough not to be lumped into CIRP’s “other” category, which includes earlier models.
