Users of high-end iPhone models, such as the iPhone 13 Pro and iPhone 14 Pro, experience the exceptional smoothness and responsiveness of their screens. These performances are made possible by ProMotion technology, which revolutionizes the visual and tactile experience. In this article, we will explore how ProMotion works, a key feature that enhances the display of high-end iPhones by offering an adaptable refresh rate.
ProMotion: What exactly is it?
ProMotion is a display technology developed by Apple that allows the screen’s refresh rate to be dynamically adjusted. But what does that mean precisely? The refresh rate refers to the number of frames per second the screen can display, measured in Hertz (Hz). Generally, standard screens have a refresh rate of 60 Hz, meaning the screen displays 60 frames per second. ProMotion takes this technology further, allowing a refresh rate of up to 120 Hz on compatible iPhones.
The Refresh Rate
The refresh rate is one of the most important aspects of the display. A higher rate offers better visual smoothness, especially when scrolling through pages or interacting with animations. On a 60 Hz screen, transitions may appear slightly choppy, particularly when navigating quickly. At 120 Hz, every movement is smoother, and motion blur is reduced, thus improving the visual experience.
Adaptability: The Heart of ProMotion
One of ProMotion’s strengths is its ability to automatically adjust the refresh rate based on the content on the screen. So, when you are viewing static text or an image, the rate can drop to 10 Hz to save battery. Conversely, when scrolling through a page or playing a video game, the rate can increase up to 120 Hz, ensuring exceptional responsiveness and smoothness. This adaptability is what sets ProMotion apart from classic screens and allows for a more personalized and optimized experience.

How does ProMotion work technically?
The LTPO Screen (Low-Temperature Polycrystalline Oxide): ProMotion uses LTPO screen technology, which allows for reduced energy consumption by adjusting the refresh rate more dynamically. Thanks to LTPO, iPhones can lower their refresh rate to as low as 10 Hz when displaying static content, which is less energy-consuming. This precise control of energy consumption helps balance performance and battery life.
The Display Controller: This component plays a central role in ProMotion’s adaptability. It analyzes in real-time the content displayed on the screen and the user’s interaction, adjusting the refresh rate as needed. For example, if you are playing a game with fast animations, the controller automatically increases the refresh rate to offer optimal smoothness.
Sensors and Algorithms: Apple uses motion sensors and sophisticated algorithms that predict refresh rate needs. These technologies detect user gestures and adjust the rate accordingly, providing a responsive and smooth visual experience.
The Adaptation Process in Detail
Activity Detection: ProMotion uses intelligent algorithms to detect the types of activities you are performing on your device. For example, if you are scrolling through text or a web page, the system detects that it is static content and reduces the refresh rate to 10 Hz or less. Conversely, for more dynamic activities like games or fast animations, it increases the refresh rate up to 120 Hz to ensure a more responsive experience.
Dynamic Rate Adjustment: ProMotion does not just instantly switch to 120 Hz for all activities. The rate is continuously adjusted and can fluctuate based on the speed of movements or changes on the screen. This dynamic adjustment allows the iPhone to optimize its resources based on usage.
Synchronization with Touch: ProMotion also allows synchronization with the user’s touch interaction. If you perform a quick action like a swipe or touch, the refresh rate is instantly increased to respond to gestures with increased responsiveness.
The Benefits of ProMotion for an iPhone User
The main advantage of ProMotion is the improvement in display smoothness. The higher refresh rate makes scrolling, page transitions, and animations much more pleasant to watch. This reduces stuttering and offers a much more natural visual experience.
Better Responsiveness
ProMotion also allows for a significant reduction in latency. During touch interactions, the higher refresh rate improves the screen’s responsiveness, which is particularly advantageous for video games and applications requiring instant responsiveness.
Energy Saving
An important feature of ProMotion is its energy adaptability. By lowering the refresh rate when it is not necessary (for example, when reading static text), ProMotion helps save battery. This intelligent energy management helps extend the iPhone’s battery life while maintaining optimal performance when needed.
Overall Improved User Experience
By combining visual smoothness, increased responsiveness, and energy efficiency, ProMotion offers a high-quality overall user experience. Navigation is more enjoyable, applications more responsive, and interaction more intuitive. ProMotion not only transforms the appearance of the screen but also the way you interact with your iPhone.
