Google wants to improve the performance and power consumption of their Chrome browser. Similar goals had already been set over the years by the developers of Mountain View, and even until a few weeks ago when a feature was identified within the Chrome 86 code that can drastically reduce battery consumption for users with many open tabs.
In an effort to improve web browser performance and reduce its impact on battery life, Google is now testing new features, some of which have been identified on the Chromium bug tracker:
- Battery saving: Google explains that it will optimize the energy consumption of websites on Chrome through the appropriate meta-tags. Ideally, Google explains, websites should be able to respect a smartphone's battery saving settings, thus improving power consumption when needed.
Battery or CPU saving is important for devices that are not connected to an electrical source, or to better share common CPU and GPU resources between running processes … Websites that are known to have high levels CPU or battery consumption may require the UA to optimize the CPU or battery, even if users have not requested it … Most modern operating systems also have power saving features that activate when the battery is low or the user wants to save battery. Ideally, websites should be able to respect these settings.
- Framerate Reduction: An additional new meta tag will allow websites to reduce framerate, thus allowing for a general slowdown in script execution and a change in behavior based on battery saving settings.
- Improved performance on Android: Google is testing a special new flag cpu-affinity-restrict-to-little-cores which according to the description should improve browser performance "limiting Chrome threads to LITTLE cores on devices with big.LITTLE or similar CPU architectures"The feature is currently in an experimental stage and therefore we do not expect it to debut in any short period.
- Back Forward Cache Feature: New feature being tested on Android that will allow users to go back and forth in the browser much faster.
