Apple never discloses sales of individual iPhone models, but both industry and Wall Street analysts expect to see clues about the Plus's sales in the ASP, or "average selling price," of iPhones overall when the Cupertino, Calif. company releases its September quarter earnings report next month, and more importantly, its December quarter financials in January 2015.
Chitika compared the share data for the iPhone 6 and 6 Plus, and found both wanting in relation to the faster share increase by 2012's iPhone 5, which within three days accounted for 2.7% of all iPhones.
The company used the iPhone 5 rather than last year's 5S because the former was the last screen size change in Apple's line. (Chitika parses screen resolution to segment the iPhone 6 from the iPhone 6 Plus; the iPhone 5S and 5C, which share display resolution with the iPhone 5, are thus all categorized as "iPhone 5.")
"While we did track the growth of all iPhone 5-type models following the release of the 5S and 5C, the observed growth may be muddled by some original iPhone 5 users jumping to the 2013 devices," said Andrew Waber of Chitika in an email reply to questions. "That being said, directly following the launch of the 5S and 5C, the share of iPhone traffic coming from iPhone 5-type models went up by roughly 0.3% over the same post-launch time frame, before growing more substantially about one week after."
Together, the iPhone 6's and 6 Plus's share amounted to 1.8% of all iPhones by Sunday, or 33% lower than the 2012 iPhone 5 at the same point in its post-sale trajectory.
