Google is working on some behind-the-scenes changes that should make Android phones feel faster while also improving battery life.
Announced by the Android LLVM toolchain team this week, Google is updating the Android kernel with “AutoFDO” – Automatic Feedback-Directed Optimization.
What is that?
In short, your phone has to make “thousands of small decisions” behind the scenes, which end up taking up a considerable portion of CPU usage. AutoFDO changes this by guiding the compiler along the “most common” execution paths, thereby reducing the load. That, in turn, leaves more horsepower for other tasks while also improving battery life by consuming less power.
Google explains:
During a standard software build, the compiler makes thousands of small decisions, such as whether to inline a function and which branch of a conditional is likely to be taken, based on static code hints. While these…
