Forget the X — iPhone 6 still hot

Apple’s new iPhone models — the

8, 8 Plus and X — are dominating tech headlines. However, a recent report from Newzoo, which tracked global smartphone usage through the end of

July, revealed that of the 730 million active iPhones worldwide, the iPhone 6 and 6s were the most popular devices.

Newzoo’s prior report, which tracked device usage through April, found the iPhone 6 and 6s controlled 21% and 18%, respectively, of the market.

The iPhone 6 and 6s remain popular for a few reasons. They were the last models with headphone jacks, and their chassis designs and larger screens represented a big leap forward from the iPhone 5s — unlike the incremental improvements in the iPhone 7 and 8.

Meanwhile, customers who were eyeing the iPhone but waiting for lower prices — particularly in overseas markets — bought the older models. These trends could be troubling for Apple, since analysts focus on the company growing its iPhone shipments every year.
