The iPhone 6s and 6s Plus were among the most popular smartphones in the U.S. on Thursday, with shipments of the phones topping 10 million in a single day, Apple said.
Sales were “stronger than expected” on the same day of the release of the iPhone 5s, the company said in a tweet.
Sales of the new iPhones were “the most popular iPhone model in the world” on Thursday at $849.88 per unit, the most of any model in a two-week period, according to Apple’s revenue report.
Sales of the 6s were up 5 percent compared with the previous week.
Sales growth for the iPhone 6 and 6 Plus was even stronger than expected, with sales up 9 percent and 7 percent, respectively, on the last week of September.
Apple is still selling about 9 million iPhone 6 units per day, and its sales are expected to continue growing through the holiday season.
The iPhone 6 was Apple’s most popular smartphone model on Thursday.
The company said the iPhone’s performance was aided by the “significant” impact the iPhone X is having on the iPhone.
Apple’s market share in the smartphone market dropped from 29 percent to 22 percent between September 20 and October 3, according in a report from IDC.
The report said iPhone X sales fell by 14 percent from the same period last year.”iPhone X continues to lead the market in terms of selling and usage,” IDC wrote.
“Apple’s continued strength in the iPhone business is also a reflection of the tremendous impact the Apple X product is having.”
The iPhone X will cost $1,000 more than the iPhone 8, and is the first phone in Apple’s lineup to feature a metal frame, the report said.
The report said the Apple 6s also had a bigger lead over the iPhone 7 Plus, which was released last week, in terms the overall market share.
The Apple iPhone 6 Plus has a larger screen and features a faster processor.
It has a better camera and an improved camera app.
