The iPhone 14 Pro and 14 Pro Max have LTPO screens with dynamic refresh rates ranging from 1Hz to 120Hz. This allows Apple to add ProMotion compatibility to the iPhone without affecting battery life. The phone understands when to increase the refresh rate, reducing energy use. iPhone owners may increase the maximum refresh rate to 60Hz for even longer battery life.
The Always-on display capability is also made possible by the dynamic refresh rate. Using the functionality, the screen will refresh at 1Hz while remaining on to display Lock Screen widgets and notifications. While the function still wastes energy, turning it off will improve battery life even further.
