Gezixuan News on November 9th, the technology media Android Authority released a blog post today (November 9th), Google in the Android 15 system, to achieve a real sense of adaptive refresh rate (ARR) function, can make the screen refresh rate dynamically adjust according to the screen content, thereby effectively reducing power consumption and jamming.

Note: Most Android phones support refresh rates over 60Hz, but in most scenarios, for phones that do not support Variable Refresh Rate (VRR) technology, in most cases, you can only switch between a few fixed refresh rates such as 60Hz, 90Hz, or 120Hz.

Android 15
Android 15 is the first version of Android to support Adaptive Refresh Rate (ARR), which not only adapts to the content frame rate, but also changes the refresh rate within a display mode.

Google says that the adaptive refresh rate feature in Android 15 has two main benefits:

First, the feature lets the device run at a rate lower than its maximum refresh rate, transitioning to a higher rate only when it's critical to the user experience, reducing power consumption and minimizing unnecessary power consumption.

Second, the adaptive refresh rate improves performance by eliminating the need to change the display mode, which Google says is a known cause of stuttering. This feature will help improve the user experience when watching videos or playing games on their phones.

Although many phone manufacturers have long advertised Variable Refresh Rate (VRR), Android didn't really support this technology until then. Previous devices were equipped with LTPO displays, but their refresh rates still relied on discrete mode switching.

Android 15's ARR feature provides a unified way to adjust the refresh rate in the same display mode, improving energy efficiency.
