A more exciting evolution is ProMotion, which is Apple's name for an adaptive refresh rate. On the iPhone 13 Pro/Max through iPhone 16 Pro/Max, and everything in the iPhone 17 lineup, the screen goes up to 120Hz for high-movement activities like scrolling or gaming. After the iPhone X introduced the notch in 2017, every subsequent iPhone carried it over without changes until the iPhone 13 line slimmed it down. The following year, the iPhone 14 Pro/Pro Max replaced the notch with the Dynamic Island, and it's been on every iPhone since (except the "e" devices). An always-on display is present on the Pro and Pro Max phones starting with the iPhone 14 Pro, and all iPhone 17 models (including the iPhone Air).
