Apple says iOS app developers need to add a plist entry for their apps to work with the 120Hz refresh rate feature
Some iPhone 13 Pro users have noticed the lack of a 120Hz refresh rate on third-party animations
A plist is a file used by iOS apps that allows the app to determine the language to be displayed, the icon used, and other important configuration data. Apple plans on handing over documents to developers to explain what they need to do in order to give their apps full access to the ProMotion 120Hz display.
Apple also discovered a bug affecting animations built with the Core Animation graphics framework. While it isn’t certain whether the issue has to do with the faster refresh rates until Apple issues a fix for the problem, some animations created using Core Animation will be forced to refresh at 60Hz.
Apple has denied the rumor that its ProMotion screen won’t work with third-party apps
This dynamic switching means your app can present smooth, seamless animations and take advantage of power-saving opportunities. Your app may already be capable of taking advantage of these new refresh rates without any changes.”
While Apple did hike the battery capacities on all of its new 2021 handsets, the 120Hz refresh rate and 5G connectivity can drain batteries pretty quickly which made the use of LTPO
a no-brainer. By the way, for those who like to accuse the company of using other’s technologies and then crowing about it as though it came from Apple itself, the firm did develop LTPO. It has been used on phones produced by other manufacturers such as Samsung and OnePlus.
