The inner workings
This feature would work on the same way battery savers work on most devices such as mobiles and laptops. The browser will work to limit the performances for certain features and also reduce all background activity. Google officially says, “Running low on battery and don’t have a laptop charger nearby? When you’re browsing the Web with Chrome and your device battery level reaches 20%, Chrome will save battery by limiting background activity and visual effects for websites with animations and videos.”
Summing up
The latest feature is set to be a part of the Chrome 108. Google stresses that this battery saving thingy is a superb add-on and will help put users in proper control of how a browser runs. Chrome can well be customized as per your preference and you will also be able to disable this mode if you so please.
