110 Million iPhones In Use In U.S.

A new study reveals that there are at least 110 million iPhones operating [n the U.S., with almost three quarters of them iPhone 6 or later models.

Of the installed base of 110 million, 62 million are iPhone 6 and 6 Plus models and 19 million are iPhone 6s and 6s Plus models, as of the end of the December 2015 quarter, according to Consumer Intelligence Research Partners (CIRP).

“The analysis reveals the strength of the strategy to offer two sizes of phones, including the larger Plus model,” said Mike Levin, partner and co-founder of CIRP. “We estimate a combined 81 million of these two format flagship phones sold in the U.S. from the September 2014 launch through December 2015. For comparison, the iPhone 5S sold about 40 million in the same period in 2013-2014. Not surprisingly, the 6s and 6s Plus did not sell quite as well as the original 6 and 6 Plus, as the first new size models accelerated upgrades last year, leaving fewer potential buyers for the second generation.”

By analyzing data on iPhone buyers, their new model selection, and their prior phones, and overlaying Apple iPhone sales data adjusted to the U.S. market, CIRP estimates the installed base grew on average 9 percent per quarter for the past eight quarters. In the December 2015 quarter, the installed base grew 11 percent, compared to 23 percent in the December 2014 quarter.

“The data again shows that growth in the installed base of iPhones in the U.S. has slowed,” said Josh Lowitz, partner and co-founder of CIRP. “Previously, we saw the installed base grow by as much as 23 percent in a single quarter, in the December 2014 quarter after the launch of the iPhone 6 and 6 Plus. Despite this, the U.S. installed base of iPhone users roughly doubled from December 2013 to December 2015, a testament to the overall power of iPhone.”
