Supporting the latest iPhone’s adaptive refresh rate displays will require a bit of work.
Apple finally brought its ProMotion adaptive refresh rate technology to the iPhone with the release of the iPhone 13 Pro. The latest model’s Super Retina XDR display will allow developers to make their animations seem as smooth as possible thanks to its peak 120Hz refresh rate—at least in theory. It turns out supporting the new ProMotion display requires a bit of finagling. A new guide called « Optimizing ProMotion Refresh Rates for iPhone 13 Pro and iPad Pro » explains how app developers can adapt their apps to the new-to-the-iPhone display technology. (ProMotion has been part of the iPad Pro lineup since 2017.) But at least part of that process will require those developers to accept that Apple doesn’t offer much control over ProMotion. « You can’t force a ProMotion display to show your content at any specific rate, » Apple said. « The refresh rate of a ProMotion display behaves differently than a traditional display.
