Screen refresh rate is 120hz but like 60hz

I have an iPhone 15 pro. The screen is 120hz but feels like 60hz. Settings are normal. I also did the last software update, maybe it will be fixed, but it didn't fix, it's like I'm using the phone at 60hz, what could be the reason?

Where are you seeing that?


I assume the Settings you are referring to also includes Settings > Accessibility > Motion > Limit Frame Rate, which should be off. And that you do not have Low Power Mode turned on where you battery indicator would be yellow.


Beyond that, third party apps must support ProMotion for you to see the full 120hz screen updates and if viewing videos, those recorded with a frame rate of 24fps would obviously not be using the 120hz screen updates either.

iPhones with ProMotion displays do not run at a refresh rate of 120 Hz all of the time.


Optimizing iPhone and iPad apps to support ProMotion displays | Apple Developer Documentation


"ProMotion displays are capable of dynamically switching between frame rates ranging from 24Hz to 120Hz on iPad Pro, and from 10Hz to 120Hz on supported iPhone devices."


"Core Animation arbitrates the animations it presents onscreen and determines the refresh rate at any particular time. Your app can provide hints to Core Animation about what refresh rates the app prefers for its animations. Take advantage of power-saving opportunities by using lower refresh rates whenever possible. Higher refresh rates can result in significant power consumption."

If you’re specifically referring to Safari, please follow this path,


iPhone > Settings > Apps > Safari > scroll down > Advanced > Feature Flags > Prefer Page Rendering Updates Near 60fps > off/disabled > restart Safari or iPhone


In accessibility turn off Reduce Motion, Limit Frame Rate, Display Pulse Smoothing and restart iphone
