The iPhone 5S is more than three times as popular as the 5C, at least according to data published Monday by Localytics.
Following their launch on Friday, the two new iPhones combined now account for 1.36 percent of all activated iPhones in the U.S., according to Localytics. The 5S scored 1.05 percent of those activations, leaving the 5C with just 0.31 percent. The means the 5S is already surpassing its lower-cost counterpart by a factor of 3.4.
Among the major U.S. carriers, AT&T's activation rates for the two new phones have been the highest at 0.67 percent of all iPhones. Verizon Wireless came in second with 0.51 percent, followed by Sprint with 0.12 percent and T-Mobile with just 0.07 percent.
The 5S is also the top dog in all launch countries combined, according to Localytics, outshining the 5C by a factor of 3.7. In Japan alone, the 5S is outshining the 5C by a factor of 5. The US has accounted for most of the activations so far, more than twice as many as those in all other markets combined.
Sales of the 5S and 5C kicked off on Friday in Australia, Canada, China, France, Germany, Hong Kong, Japan, Puerto Rico, Singapore, the UK, and the US.
To compile its data, Localytics analyzed more than 20 million iPhone activations in the US and abroad from Friday through Sunday.
