Android 15 Introduces True Adaptive Refresh Rate Support for Smartphones and More Devices

While support for adaptive refresh rates has been available since Android 11, Android 15 takes the concept a step further with a more refined method. Previously, adaptive refresh rate (ARR) was implemented through refresh rate switching, where the device would switch between predefined display modes—such as 60Hz, 90Hz, 120Hz, or 144Hz—depending on the content being displayed. However, Android 15 introduces true ARR, which enables the system to adjust the refresh rate within a single mode, making the experience far more fluid and seamless.

This update allows displays with ARR support to decouple the VSync (vertical synchronization) rate from the refresh rate, meaning the system can sync the frame rate with the content’s cadence more precisely. By dynamically adjusting the refresh rate based on the specific content being viewed, the device can offer smoother visuals without sacrificing performance or battery life. This is a significant leap forward compared to older methods of refresh rate switching that often involved larger jumps between fixed modes.

The introduction of true ARR in Android 15 offers two key benefits for users: improved battery efficiency and reduced stuttering, or “jank,” during transitions. With ARR, the device can lower its refresh rate during less demanding tasks, like reading static text or browsing, thereby conserving power. Simultaneously, when viewing fast-moving content, such as videos or games, the refresh rate can ramp up for a smoother experience. This results in a more responsive and energy-efficient display that adapts intelligently to the user’s activity.
