Apple is preparing for its biggest iPhone sales on record next year, which will mark the 10th anniversary of the smartphones, Apple Insider reported on Tuesday.

Next year’s sale is set to outperform the iPhone 6 series, the most popular models to date.

Apple could sell up to 150 million iPhones, analyst Ming-Chi Kuo of KGI Securities revealed in a note to investors obtained by Apple Insider. Suppliers are bracing for the demand for the new phones, which could have a new design and technology like wireless charging.

Apple is expected to release three new iPhones, KGI securities says. Suppliers are gearing up to make 120 million to 150 million iPhones in the second half of 2017. The number this time around is higher than when suppliers prepared for the release of the iPhone 6, which was 110 million to 120 million.

Apples 2017 upgrades will lead to "unprecedented replacement demand," Kuo says. The iPhone 8 rumors and improvements include the new high-end OLED model, which will encourage consumers to upgrade their iPhone devices, while the other two new models with LCD screens will have "notably superior specifications," Kuo says.

Other iPhone 8 features that could be included in the new models are a glass back and a bright, flexible screen. Those upgrades could bring in even more sales, Kuo predicts. Outside its normal September unveiling, no hints at the official iPhone 8 release date have been reported.
