In summary:
- Tech Advisor reports that Google is implementing Automatic Feedback-Directed Optimisation (AutoFDO) to enhance Android’s core operating system performance across smartphones.
- Initial Pixel phone tests show promising results with 4% faster cold app launches, 1% quicker boot times, and improved battery life through optimized code prioritization.
- Google plans to expand AutoFDO beyond kernels to other OS aspects, potentially benefiting all Android device manufacturers with snappier interfaces and better responsiveness.
Google has confirmed that it’s working to optimise its mobile OS, potentially bringing about a performance upgrade for all Android smartphone users.
Over on the official Android Developers blog, a fresh post from Software Engineer Yabin Cui has shed light on a new optimisation technique that’s being applied to the Android kernel – essentially the foundation of the operating system.
The Android LLVM toolchain team is working to bring Automatic Feedback-Directed Optimisation (AutoFDO) to Android’s code, which promises “significant performance wins for users”.
It’s all very technical, but it seems that AutoFDO uses real-world usage patterns to guide Android’s core operation. Google basically ran a bunch of tests using Pixel phones, simulating the launch of the 100 most popular apps. The elements of code that are more frequently used are then able to be prioritised in subsequent builds.
Given that the Android kernel accounts for about 40% of CPU time, any such improvement is likely to be meaningful. The poster anticipates a 4% cold app launch improvement and a 1% boot time reduction, which sounds pretty minor, but should provide a tangible upgrade.
“These aren’t just theoretical numbers,” says Cui. “They translate to a snappier interface, faster app switching, extended battery life, and an overall more responsive device for the end user.”
Google is initially rolling out this new AutoFDO technique to the android16-6.12 and android15-6.6 branches, which feed the most recent Android releases. It plans to expand its use to other aspects of the OS, which could help smartphone manufacturers to optimise the running of various hardware drivers.
In other words, Google’s Android kernel improvements could be used in future to speed up the running of your Samsung or Xiaomi phone’s camera.
