At the beginning of the classic version of Edge, Microsoft did an experiment to show the excellence of its browser in terms of battery life. After switching from EdgeHTML to Chromium, Microsoft also gradually ported the functionality of the classic Edge to the new Edge and contributed the technology to the Chromium community.
Chrome Cunningham, an engineer at Google Chrome, recently confirmed that Google plans to deploy the improvements in Chrome to further improve its performance in practice. This includes eliminating unnecessary disk caches while watching videos and instead caching to RAM, keeping the disk idle for longer and saving battery life.
Another improvement is checking whether your computer is plugged in or equipped with a battery, which allows browsers to use more sophisticated power-saving technologies only when needed. There is also an o-comparison of http response content sizes, which is not cached when the dimensions are larger than the maximum file capacity.
We’ll see these improvements in the Chrome Canary channel version soon.
