Chrome may soon let websites go into a battery-saving mode

Chrome may have the majority of the web browser market, but it’s definitely not because it’s the most energy-efficient option on the market. In fact, Google’s browser has become known, both justified and exaggerated, for quickly depleting a laptop’s battery. Google has tried to fight this stigma, both in marketing and at the technical level, and a new feature can be added to its growing list of battery saving features that, hopefully, will prevent some sites from running out of battery.

To be fair, part of the blame for battery consumption can be attributed to the websites themselves, especially those with rebellious use of Javascript and system resources. Google can’t exactly force all of these sites to behave properly, at least not yet, and it’s Chrome’s responsibility to mitigate the effects of energy-consuming websites and web applications.

A Chrome experiment unveiled last month involved practically putting some web pages to sleep when they are in the background, limiting Javascript timers that unnecessarily consume CPU processes and, therefore, battery consumption. This time, Google is giving sites the option to “suggest” an energy-saving mode that Chrome will use.

How exactly this will work is still unclear, but sites can use special codes and tags to indicate that they want Chrome to optimize for battery or CPU. This can, for example, allow web video conferencing applications to run for as long as necessary, but only using battery power. Chrome can reduce a page’s frame rate or slow down the execution of your script to save energy and CPU cycles.

Most importantly, however, this new system will also allow web pages to adjust their performance, depending on whether the user has switched the operating system to a power saving mode. This will help to make web applications, particularly Progressive Web Apps or PWAs, more aware of the operating system’s battery modes and behave more like native applications.
