Google Chrome packs several tools to provide a good experience on the web. The new Heavy Ad Intervention tool in Chrome blocks abusive ads that drain the device’s battery, data plan, and other resources. Here’s how to turn on Heavy Ad Intervention in Chrome for Android and Desktop.

If you feel your Android phone warm up while you’re browsing the web or your PC/laptop/Chromebook makes high noise (cooling fan spins faster) when on a web page, then it might be due to purely coded and unoptimized ads on the web page. Chrome’s new Heavy Ad Intervention tool blocks such ads and stops eating up of a battery, data plans, and system resources.


Chrome product manager Marshall Vale explains on Chromium blog how this feature works. “When an ad uses 4MB of network data or 15 seconds of CPU usage in any 30 second period or 60 seconds of total CPU usage, Chrome will shut down the ad”.
