flag Google’s AutoFDO boosts Android performance by optimizing code usage, improving speed and battery life on Pixel devices starting with Android 15.

flag Google is rolling out AutoFDO, a new performance optimization in the Android kernel, to make devices faster and more responsive without hardware changes. flag By analyzing real-world usage of the top 100 apps, AutoFDO helps the compiler prioritize frequently used code paths, improving app launches, scrolling, and switching. flag The update, starting with Android 15 and 16, enhances the kernel—which handles core system functions and uses about 40% of CPU time—leading to smoother performance and better battery life. flag The changes are applied automatically in the background across Pixel devices and will expand to other manufacturers over time.
