IPhone 13 Pro, iPhone 13 Pro Max does not fully use 120Hz

The iPhone 13 Pro and iPhone 13 Pro Max reportedly reduced some animation to less than 120Hz.

The brightest feature on the new models of the iPhone 13 Pro and iPhone 13 Pro Max is Apple’s highly influenced ProMotion. The feature has been available on the iPad Pro since 2018, offering a smooth experience with a refreshing rate of 120Hz. On newer iPhones, a higher level of refinement makes for a smoother scrolling and a better gaming experience. However, there is a problem with this feature in the beginning.

According to a report from 9To5Mac, the ProMotion feature on the iPhone 13 Pro and iPhone 13 Pro Max does not work consistently. While all scrolling is done at full 120Hz, animation and conversion does not occur consistently in all applications. Third-party applications reportedly keep the update rate up to 60Hz only.

The iPhone 13 Pro 120Hz series is not compatible
The report states that all Apple apps can take advantage of the 120Hz refresh rate in all cases. However, most animations in third-party applications are limited to 60Hz. This may violate the compatibility of iPhone 13 Pro and iPhone 13 Pro Max users.

When the issue was raised with Apple, the company said developers needed to work on their operating systems to support high frames. The problem is most evident with apps and games using a custom rendering engine. Developers will need to add the info.plist key to allow their applications to support the 120Hz update rate. Procedure documents will be available to developers shortly.

At the same time, Apple will also release a bug fix update that prevents Core Animations from driving the refresh rate above 60Hz.

Is the inconsistency very apparent? In our iPhone 13 Pro Max unit, this problem is not visible to the average user. In fact, a high level of refinement makes the iOS experience smoother than ever. Next to the 60Hz display of the iPhone 13 Mini and iPhone 13, the 120Hz display on the Pro Max makes animation look good.

Rumor has it that the upcoming iPhone 14 will have a 120Hz update rate as normal throughout the range. The only difference is expected to have a variety of four iPhone models. Apple is rumored to be releasing the Mini iPhone next year and has a Max version of the non-Pro model. So, you can expect an iPhone 14 and an iPhone 14 Max.
