Apple launched the iPhone 13 series earlier this month. The new iPhone models come with a bunch of incremental upgrades over the outgoing models, especially in the camera and battery departments. The Pro models got an exclusive feature this year, which is the introduction of a ProMotion display. Apple finally introduced the iPhone 13 Pro and Pro Max models with a dynamic 120Hz OLED display. The premium variants of the iPhone 13 series switch between 10Hz and 120Hz depending on the on-screen content. While the feature is supposed to make the user experience better, it looks like not all apps can take advantage of the butter-smooth refresh rate tech.
The iPhone 13 Pro and Pro Max (the two more expensive handsets) have a refresh rate of 120Hz, which is double the 60Hz seen on the iPhone 12 smartphones. That means every second, the screen can refresh (or ‘redraw’) what’s displaying 120 times, as opposed to 60 times for a 60Hz screen. Hence fast-moving content like games, action movies and sports will have less blur, ghosting and artefacting on the 120Hz display than the 60Hz.
