But users sometimes have problems with Google Chrome using too much CPU, which causes screen or mouse lag, a quickly draining battery, or other troubles.

Step 1. Click the three dots menu icon in the upper right corner of Google's browser.

Running too many plug-ins or extensions will result in high CPU usage. So we need to disable unnecessary extensions. Additionally, poorly designed extensions or even malicious extensions would cause a high CPU usage or even corrupted Chrome. So, when Google Chrome uses too much CPU, you should check extensions carefully and delete unsafe extensions.
It's kind of easy to delete or disable extensions. Copy and paste chrome://extensions/ on the search bar of Chrome to see all extensions. Click the slider in the lower right corner to disable extensions. Click the "Remove" button to delete extensions.
