Apple’s iPhone 5s and iPhone 5c were most popular with previous iPhone owners updating from older iPhones, according to brand-new information collected by Customer Knowledge Research Partners.

Approximately 65 percent of overall iPhone 5s/5c buyers in the United States formerly possessed an iPhone, compared with 55 percent of iPhone 5 buyers a year back. While 12 percent of customers who bought an iPhone 5 in 2012 were updating from an iPhone 4s, simply 6 percent of iPhone 5s/5c buyers upgraded from an iPhone 5, with the remainder of the previous iPhone purchasers coming from older models like the iPhone 4 and 4s or non-iPhone devices.

The absence of interest from iPhone 5 owners is likely due to the fact that the iPhone 5s and the iPhone 5c are somewhat small updates that have actually not resulted in a modification in form element. The iPhone 5c in specific utilizes the same elements found in the iPhone 5, and it’s possible that ongoinged iPhone Fives scarcities have actually discouraged some iPhone 5 owners from updating to the current model.

‘We see a noticeable reduction in the number of iPhone buyers that appear to desire the most up to date, most advanced phone,’ said Josh Lowitz, Partner and Co-Founder of CiRP. ‘For the iPhone 5S/5C, 6 % of buyers upgraded from the year- old iPhone 5. In contrast, at the launch of the iPhone 5 in September 2012, 12 % of clients upgraded from the year-old iPhone 4S.’ Within the two-thirds of iPhone buyers that updated from an existing iPhone in September and October 2013, many fewer upgraded from the year-old iPhone 5, relative to the 55 % of iPhone 5 purchasers in September and October 2012 that updated from the year-old iPhone 4S.

The iPhone Fives and 5c also saw higher adoption numbers from former Android users, though adoption by former basic phone individuals and BlackBerry individuals decreased, most likely due to a loss of general market share in those groups.

CIRP’s information is based on a study of 400 UNITED STATE iPhone buyers that activated a phone after the September 20 launch of the iPhone Fives and 5c.
