Apple Inc.’s iPhone 8 posted the weakest sales of any of the company’s new smartphones in recent years, according to estimates by two market research firms, raising the stakes for the higher-priced iPhone X as advance orders start on Friday.
In the U.S., Apple’s largest market, the iPhone 8 and its larger 8 Plus version accounted for 16% of all iPhone sales in the September quarter, according to Consumer Intelligence Research Partners LLC.
