Apple says an issue is preventing some animations from using high refresh rates on the iPhone 13 Pros
Apple’s iPhone 13 lineup launched Friday, and one of the key features of the 13 Pro and 13 Pro Max is their ProMotion displays with variable refresh rates that can top out at 120Hz. But as noted by 9to5Mac, some app animations in third-party apps currently only run at 60 Hz. That could be frustrating if you expected buttery smooth animations in all your apps with the new phones, but when we asked Apple what’s going on, the company shared two reasons why this could be happening.
One reason is that developers need to update their apps to indicate that they are using the higher refresh rate. This can be done by adding an item to the app’s plist, says Apple The edge, and the company says it plans to share documentation about the item you need to add soon. But in some cases, animations created with the company’s Core Animation technology are also affected by an issue that will be fixed in an upcoming software update, Apple says.
Variable refresh rate screens offer many benefits, including smoother animations and scrolling when you use the device and battery saver, the screen operates at lower refresh rates. We were impressed with the screens on the 13 Pro and 13 Pro Max in our review, and it’s good to hear that third-party apps can take full advantage of what they have to offer, although some may have to wait until after that software. update.
