Margin even higher in some other countries
The iPhone 5s appears to be outselling the iPhone 5c by a ratio of 3.4 to 1 in the US, according to marketing and analytics firm Localytics. About 1.05 percent of all American iPhones are said to be the 5s, while the 5c represents just 0.31 percent. "This makes sense since those who feel the need to buy a new device the very weekend it launches are most likely the power users who want the highest-end phone experience," writes Localytics marketing VP Bernd Leger.
AT&T continues to control the most iPhone activations in the country; 5s and 5c models on the carrier represent 0.67 of all US iPhones. Verizon's equivalent share is 0.51 percent, while Sprint and T-Mobile are at just 0.12 and 0.07 percent, respectively. Typically the 5s' popularity is reflected at each carrier, although Sprint is closer to maintaining an even balance.
Internationally, the US continues to be the heart of iPhone sales, vastly outdoing regions like Japan, western Europe, and China. The 5s' dominance is even more pronounced on a global scale, where the ratio is 3.7 to 1. In some individual countries the difference is even higher, an extreme example being Japan's 5:1 gap.
The 5s and 5c launched just last Friday, and the Localytics data is based on tracking of over 20 million iPhones between then and Sunday at 8PM Eastern. Apple says it has already sold over 9 million units of the new models, though it hasn't shared any deeper details.
