Apple sold more than 13 million iPhone 6s and iPhone 6s Plus units three days after their launch, the company said Monday.
"Sales for iPhone 6s and iPhone 6s Plus have been phenomenal, blowing past any previous first weekend sales results in Apple's history," CEO Tim Cook said in a release. "Customers' feedback is incredible and they are loving 3D Touch and Live Photos, and we can't wait to bring iPhone 6s and iPhone 6s Plus to customers in even more countries on October 9."
The company also said the new models will be available in more than 40 additional countries starting Oct. 9, including Italy, Mexico, and Spain.
Apple shares were slightly higher in the premarket.
The new smartphones were unveiled at a Sept. 9 event in San Francisco.
