Apple’s recent update, iOS 18, has caused frustration among users of the iPhone Pro series. The ProMotion display, known for its smooth performance, now seems to be limited to 80 Hz. Users are noticing a drop in display quality, sparking criticism. The ProMotion is a key feature on iPhone Pro models, first introduced with the iPhone 13 Pro. It allows refresh rates of up to 120 Hz, offering a smooth experience when scrolling or using apps. This technology was a major advantage for these models, making them stand out from iPhones without ProMotion. However, with iOS 18, users have noticed a change in the iPhone ProMotion display. According to a popular and authoritative tech blogger, Ice Universe, the refresh rate is now capped at 80 Hz, leading to a less fluid display.
