With four iPhone 12 models expected to arrive later this year, Apple will be breaking down the lineup in two affordable variants, followed by two ultra-premium versions. Naturally, the two ultra-premium versions are the iPhone 12 Pro and the iPhone 12 Pro Max, and apart from the upgraded specs, the increased number of cameras, and a more luxurious build, there’s something else Apple could incorporate in order to differentiate these pricier handsets. That happens to be a 120Hz ProMotion display, followed by another change.

Yet again, there’s something else setting apart the iPhone 12 family. The upcoming models have been rumored to feature a 120Hz refresh rate, along with variable refresh rate technology support. This would allow the upcoming iPhones to quickly switch between the refresh rate depending on what was being viewed on the display to conserve battery life. Unfortunately, Bloomberg reporter Mark Gurman believes that this 120Hz ProMotion technology will only arrive for the more expensive iPhone 12 Pro and iPhone 12 Pro Max, meaning that less expensive versions will stick to 60Hz.
