According to the latest information from expert Ross Young of Display Supply Chain Consultants , the iPhone 17 and iPhone 17 Air models launched next year will be equipped with screens with 120Hz ProMotion technology.

iPhone 17 and iPhone 17 Air may be equipped with 120Hz ProMotion technology display.

This means that the displays on the iPhone 17 and iPhone 17 Air (the thin iPhone model expected to replace the iPhone 17 Plus) will be able to increase the refresh rate up to 120Hz to provide smoother scrolling and better video viewing when needed.

ProMotion will also allow the display on the iPhone 17 and iPhone 17 Air to drop to a more power-efficient refresh rate.

iPhone 13 Pro models can drop to 10Hz, while iPhone 14 Pro through iPhone 16 Pro models can drop to 1Hz, allowing for an Always-On Display with information on the lock screen even when the device is locked.

However, it's unclear whether the iPhone 17 and iPhone 17 Air will drop to 10Hz or 1Hz.

For comparison, the newly launched iPhone 16 and iPhone 16 Plus duo still use screens with a 60Hz refresh rate. Meanwhile, the ProMotion screen is only for the "Pro" models.

Ross Young is known as a source with a fairly high level of accuracy when providing information about the screens on new Apple products.

Before the iPhone 16 series was released, Young was also the first to reveal that the iPhone 16 Pro and iPhone 16 Pro Max duo would have larger screens, 6.3 inches and 6.9 inches respectively.

The iPhone 17 generation is expected to be launched by Apple in September 2025.
