iPhone 13 Pro and 13 Pro Max have a unique function of changing the frame rate of the screen based on user activity

As you know, the older models of the iPhone 13 line support variable display frame rates. Depending on the conditions, the frequency can vary from 10 to 120 Hz. 

However, another curious detail has now come to light. It turns out that the frequency can change not only depending on the application or the load on the smartphone. The iPhone 13 Pro and 13 Pro Max have a feature that changes the display frame rate depending on how quickly the user's finger slides across the screen.  

For example, if a user opens the Twitter app and reads a message, the frame rate will drop to 10 Hz. If the user starts to scroll slowly through the information, the frequency will increase up to a certain limit. For example, up to 60 Hz. If you start flipping more actively, the frequency rises to 90 or 120 Hz.  

With this feature, Apple smartphones can save energy more efficiently. And we have already seen that numerous tests demonstrate the excellent autonomy of the new products. True, he will not forget about the significantly increased batteries.
