Google has not stopped exploring in this area. According to TheWindowsClub , Chrome recently launched an experimental feature called Battery-Savings (Meta Tag). This feature is designed to allow the site to recommend appropriate power saving measures to Chrome by following the user’s computer battery settings.
In terms of specific implementation, user agents (User Agents) can reduce the frame rate by reducing the animation frame rate (allow-reduced-framerate), or if the video is playing, the animation frame rate can be compared with the observed video The playback rate is matched. It achieves a reduction in script speed (allow-reduced-script-speed) by placing execution threads or processes on a small core instead of a large core.
The complete function will include the following aspects:
metatags that allow sites to indicate the preferred mode
- Media queries, allowing websites to adjust style sheets based on battery settings
- The site should follow the power saving mode of the user or operating system
- User Agents will follow the meta tags on the website unless it conflicts with user or operating system settings
This feature is expected to be launched with Chrome v86 or v87. By then, Chrome's consumption of CPU and power may be greatly improved.
