Chromium browser high CPU usage issue is not rare. If you are having this problem, this article will guide you on how to fix it.

Chromium is right now the most popular and compatible browser engine. Many independent browser makers like Opera and even the tech giant Microsoft have given up on their browser technology and adopted Chromium.

If you look at the best web browsers, you will notice that most of them are based on Chromium.

The above statement proves how powerful Chromium is. Even though Chromium-based browsers can outperform all other browsers in terms of performance, speed, and compatibility, people still may face some problems.

High CPU usage is one of the most common and annoying limitations of Chromium that is creating problems for low-end device owners.

Why does Chromium use so much CPU?

There are many reasons Chromium-based browsers may use much CPU power on your computer. Here are the most significant ones:

  • The Chromium-based browser uses hardware acceleration and multi-threading by default
  • Third-party extensions and services may utilize more CPU power
  • Too many extensions can use too much computing power
  • Browsing unoptimized javascript-based websites
  • Operating system issues

Fortunately, you can reduce Chromium browsers’ CPU usage significantly by following the methods shown below.
