If true, it will not be the first time Apple has launched mobile devices to market with 120Hz shows - all of its 10.5-inch and 12.9-inch iPads launched since 2017 have boasted ultra-fast refresh rates, albeit without the advantages of OLED technology, such as individually-lit pixels, flawless blacks, and low power consumption.
Unlike the iPad Pro, which uses an LED-backlit Retina screen, the current iPhones sport an OLED panel, with Samsung manufacturing the displays. According to a rumor via Ice Universe on Twitter, the Cupertino tech giant is considering giving next year's iPhone lineup 120Hz displays. So far, analysts and leaks have pointed to the 2020 iPhone featuring 5G connectivity, three new different display size, and more.
ProMotion makes scrolling pages and using Apple Pencil buttery smooth. Currently, the iPhone Xs (as with the iPhone X) are stuck with standard 60Hz panels even though they enjoy the other key benefits of OLED displays including inky blacks and HDR.

Democrats have signaled they intend to focus much of their questioning on the episodes that Mueller outlined in his report in which Trump sought to impede the investigation.
The ProMotion display are now used in Apple's iPad Pro and they could also be coming to the iPhone next year. In order to achieve that, the iPhone-maker is allegedly already discussing the topic with Samsung and LG, its main display panel suppliers.
The tweet by Ice Universe identified the new iPhone display as a "switchable 60Hz/120Hz refresh rate screen" suggesting that it would implement a similar variable refresh rate technology.
