Apple hasn’t revealed how many iPhone X units it sold in the fourth quarter, but a new study from researcher Canalys has put a number on it.
The tech giant sold 29 million iPhone units in the fourth quarter, including 7 million in the U.S., Canalys said in a statement on Tuesday. That was enough to make the iPhone X the most popular iPhone Apple sold during the period, topping the iPhone 8 and iPhone 8 Plus.
Apple unveiled the iPhone X in September and released the handset in November. The iPhone X is the most expensive smartphone Apple has ever released with a starting price of $999. For that, users get a dramatically redesigned iPhone that ditches the physical home button in favor of a 5.8-inch screen that nearly entirely covers the handset’s face. It also comes with support for a new Apple biometric technology called Face ID that scans a person’s face to unlock the smartphone and verify mobile purchases via Apple Pay.
