Android phones are getting faster thanks to new kernel optimization

Google has announced a new optimization technique designed to improve the performance of Android devices. The change focuses on the Android kernel, the central part of the operating system that manages the hardware and system processes.

The new technology, called Automatic Feedback-Directed Optimization (AutoFDO), will help Android devices run faster and more efficiently by analyzing how apps behave in real-world scenarios.

Android will use real-world data to optimize performance

Traditionally, Android system components have been optimized using static code analysis, which applies general performance improvements regardless of how people actually use their devices. AutoFDO changes this approach by allowing the system to be optimized using real usage data.

Google’s Android LLVM toolchain team collects this data by testing the top 100 Android apps and analyzing how they interact with the system. The information is then used to guide the compiler so it can make smarter decisions about how Android should run. This allows the system to better optimize tasks such as app launches, background processes, and system responsiveness.

Expected Android performance improvements

Google says users should see a snappier interface, faster app switching, longer battery life, and an overall more responsive device. The profiles that power AutoFDO require continuous updates to remain effective, and Google says it will continue to monitor and retrain the data to maintain performance.

AutoFDO update already used in recent Android versions

Google says the new optimization profiles are already being used in Android 15, Android 16 and Android 17 development builds. The company continues to update these performance profiles to ensure devices remain optimized as Android evolves.

While Android devices are already known for being fast on modern hardware, these changes aim to make the experience even smoother on a wide range of devices, including older smartphones.

With Android 17 expected later this year, Google appears to be focusing heavily on performance and efficiency improvements along with new features.
