According to ad impression data provided by Chitika, the adoption rate for the iPhone 6 is more than 7x higher than the iPhone 6 Plus. On the Monday following launch, the smaller iPhone accounted for 1.5 percent of North American web traffic, compared to 0.2 percent for the iPhone 6 Plus.
Mixpanel, which measures mobile app usage, reports similar results with the iPhone 6 reaching 2.72 percent of measured traffic and the iPhone 6 Plus trailing with 0.54 percent. Mobile analytics firm Fiksu provides a third set of mobile metrics that also suggest the iPhone 6 is more popular among launch day iPhone purchasers.
Chitika explains these results by suggesting that the iPhone 6 Plus may be less popular among consumers because it is niche product due to its larger screen size. Supply constraints also may be a factor, with the iPhone 6 Plus selling out quickly online and reportedly being available only in limited amounts this weekend in stores.
