AutoFDO Update Boosts Speed and Battery Life on Newer Android Devices
On March 12, Google announced a significant behind-the-scenes update to the Android kernel designed to increase device speed while extending battery life. The new feature utilizes Automatic Feedback-Directed Optimization (AutoFDO), developed by the team at LLVM's toolchain division in San Francisco and tested on devices running newer versions of Linux kernels starting with version 5.x or later, such as Pixel phones from Google.
Key Points
-
1Google announced a new technology called AutoFD to update its underlying Linux kernels for faster performance.
-
2The project aims specifically at improving battery life alongside speed by optimizing the Android kernel.
