Apple introduced ProMotion technology with the release of the iPhone 13 Pro and iPhone 13 Pro Max, allowing both flagships to run their displays at 120Hz, delivering a buttery smooth experience when performing tasks such as swiping, scrolling, or browsing through a multitude of applications.
With iOS 18, which was publicly released last week, Apple has introduced a few changes, but some of them were implemented without informing those who updated their devices to the latest software update.
One of them was noticed by a tipster, and he has posted video evidence showing that iOS 18 has limited an iPhone’s refresh rate to 80Hz instead of letting it run at the default 120Hz.

Instead, he reports that there is a limitation set in place that prevents an iPhone’s refresh rate from going above 80Hz. He has posted video evidence below on X, showing that during a brief rapid scrolling session, a device that appears to be one of Apple’s latest iPhone 16 models does not go beyond 80Hz, and there are only minor faints showing that the screen touches 120Hz.
The refresh rate counter is visible, which may have appeared thanks to the installation of a 3rd-party application, showing the limitation introduced in iOS 18.
