Apple says it sold more than 10 million iPhones in the first weekend after its new models went on sale on Friday.
Chief Executive Tim Cook said the company could have sold even more iPhone 6 and iPhone 6 Plus models if it weren’t for the supply constraints the company tends to face in years that involve a re-design, with screen production a major concern this year.
Analysts had estimated first-weekend sales of up to 10 million iPhones, after Apple booked record pre-orders of 4 million on September 12, the day pre-orders opened.
"Despite the supply chain constraints around the iPhone 6 Plus and tightness around certain models of the iPhone 6, we believe (Monday's) strong print demonstrates that Apple executed extremely well in the face of severe supply constraints," Cantor Fitzgerald analyst Brian White wrote in a note.
First-day pre-orders of the new phones, which went on sale in 10 countries, far surpassed the two million first-day pre-orders for the iPhone 5 model two years ago.
"While our team managed the manufacturing ramp better than ever before, we could have sold many more iPhones with greater supply and we are working hard to fill orders as quickly as possible," Cook said in a statement.
Last year, Apple sold 9 million iPhone 5S and 5C models in 11 countries, including China, in the first weekend they were available. Sales of the latest models in China, the world's largest smartphone market, have been delayed by regulatory issues.
Apple sold 5 million iPhone 5 handsets, 4 million iPhone 4S models and 1.7 million iPhone 4 units during the first weekend.
The company said last week that many US customers would have to wait until next month for their new iPhones due to strong demand. The new iPhones will be available in 20 more countries on September 26.
