Chrome is one of the major web browsers we use today. Google knows this and wants the experience we receive from Chrome to be as optimum as possible, not only accelerating page load but also reducing energy consumption, as energy efficiency is one of the key pillars in Chrome according to Google.
In this sense, the company has indicated that Chrome 57, the version of Chrome released last week for Windows, Linux and Mac computers, has a new mechanism of regulation that consumes 25% less energy compared to previous versions.
This mechanism has been fixed in the tabs in the background that, according to Google, reduces the consumption of a third of power of Chrome in desktop computers. What has basically been done is to delay the action of the timers to limit the average CPU load to 1% of a kernel if an application uses too much CPU in the background. This mechanism will not affect those background tabs that are playing audio or maintain real-time connections, such as WebSockets or WebRTC, as detailed.
From Google they notice that in the long term it is ideal to totally suspend these tabs and use new APIs to develop the work in the background. Obviously, the company promises that they will continue to take steps to reduce the energy impact of using Chrome in the use of batteries of equipment and devices, as in this case.
