iOS 15.4 beta adds ProMotion support for all apps

Apple has officially released the beta build for iOS 15.4 and along with a slew of new features, they have also added in support for ProMotion 120 Hz refresh rate for all apps across the board.

Apple shook up their iPhone lineup with the introduction of a 120 Hz refresh rate for their iPhone 13 Pro Lineup. However, a bit of a deal-breaker was that only system apps were able to leverage this refresh rate to enhance the experience of the users. With iOS 15.4, it looks like all developers will now be able to leverage this refresh rate and make their apps a lot more fluid and enjoyable.

It looks like Apple was able to squash the Core Animation bug that wouldn’t allow animations to go beyond 60 fps. However, we can’t confirm whether all apps will run at 120 fps automatically or some developers would need to tinker with the code of their apps as well.

If you are an Apple Developer, you can download the iOS 15.4 beta build by heading to the General settings and checking for software updates.
