There is an experimental feature being developed by Google called Chrome that saves the CPU and extends laptop battery life. Starting with version 105, a feature update will be released.

Currently, Google is testing a function called 'Quick Intensive Throttling' (fast intensive throttling). It is intended to enormously expand the functionality of a feature that was introduced with version 87 of Chrome.

Intensive Wake Up Throttling' was introduced in Chrome 87. When a tab is suspended and hidden for more than five minutes, JavaScript will not call it more than once per minute.

By making this change, Google was able to reduce Chrome's CPU usage by a factor of five, resulting in an increase in the laptop's battery life to up to 1.25 hours. After that, Google has not touched on this function again - now it is being enhanced.

Google is now testing reducing this grace period from 5 minutes to 10 seconds, so that paused tabs can reduce CPU load more quickly and extend battery life more effectively.

A new feature is available in the JS Timer Intensive Wake Up Throttling that adjusts the timer wake-up intervals to 1-minute intervals after a 5-minute grace period.

In order to introduce intensive wake throttling with a minimum risk of regression, we chose a time span of five minutes to be very conservative.

In view of this, we are currently considering reducing the timeout to 10 seconds, but only with regard to pages that are considered loaded when they are hidden.'

Chrome Canary and Dev versions are being tested for the new feature. The fast throttling can be found under chrome://flags/#quick-intensive-throttling-after-loading if you wish to test it.
