5 Quick Methods to Fix High CPU Usage in Brave Browser

  • High CPU usage of browsers is one of the most common problems that users face. 
  • Browsers are among the most resource-intensive programs, and they can easily consume more than 100% of a CPU core. 
  • In this article, we focus on how to reduce high CPU usage, particularly in the Brave browser.

Brave browser is designed to run as a lightweight browser that doesn’t bog down your computer’s resources. It has features that make it faster than other browsers such as Chrome, Firefox, or Safari.

One of these features is called Brave Shields. It allows you to block unwanted content like ads and trackers without having to install any extra extensions or plugins. 

But sometimes Brave can use too much CPU power. This will in turn slow down your computer, especially if you have an older PC. It can also drain your battery, but we have a dedicated article on how to fix that.

If you find that the browser is using too much of your CPU power or RAM, you can install The Great Suspender extension to get rid of unused tabs.

Does Brave Browser use a lot of CPU? 

Brave is a fast, secure, and safe browser that blocks intrusive ads and trackers by default. While we all appreciate the blocking of ads, this, in turn, means that the browser uses more CPU power.

High CPU usage can cause slow performance and even make the computer seem unresponsive. This is especially true for computers that are already struggling with performance issues.

You may want to consider another browser, especially if you find yourself asking: Does Brave use less CPU than Chrome? Brave is built on Chromium, so it inherits all of its performance characteristics and stability. 

However, your activities will determine how much CPU your browser consumes, so the difference is negligible. 

Quick Tip:

To enhance laptop battery life, Opera provides a built-in energy saver mode that reduces CPU load and performs additional changes.

These changes include suspending theme animations, minimizing background tab activity, and pausing unnecessary plugins. This option does not conserve RAM or Internet resources, but it does reduce CPU usage, which is highly beneficial.



When using a laptop, Opera has many trigger settings to engage the power saver function automatically.

How do I lower CPU usage in Brave Browser? 

1. Update your browser

The first thing you should do is update your browser because old versions of Brave use more CPU resources than newer ones do.

So if you haven’t updated in a while, go ahead and do that now before continuing with the rest of this guide.

2. Close all tabs and windows 

If you are not actively using any additional tabs or windows, it is best to close them. This will reduce the memory footprint of the program, which can help lower CPU usage. 

The more tabs you have open, the more memory Brave uses. Try closing some tabs if you’re having trouble with lagging.

3. Disable plugins 

Whereas add-ons and extensions add more functionality to a browser, sometimes they are the culprits that are responsible for high CPU usage.

You can disable plugins such as FlashPlayer if they aren’t needed for viewing content on a website. These are known to increase resource usage by up to 400% so disabling them will greatly improve your PC’s performance.

4. Disable hardware acceleration

Browsers often use the hardware acceleration feature for pages to load faster. However, if you have a low-end GPU, then you may experience slowdowns in your browser.

If you are experiencing slowdowns while browsing websites, then try disabling this option and see if it helps improve your performance.

5. Clear cache and cookies

If you notice some performance issues with your Brave browser, the first thing you should do is clear your cache and cookies. 

This will remove all cookies and cached data from your device, which will help decrease CPU usage by Brave in the long run.

If you want to remove it automatically, third-party software such as CCleaner will delete your browser history, cookies, and cache files for any browsers you’ve installed, including Brave.

It will also delete the cookie data stored by the Flash Player. CCleaner will remember your preferences for the next time you open it, so you can just launch it and click the Run Cleaner button in the future.

Which browser has the lowest CPU usage?

When you compare top browsers side by side and look at the process graph, which shows CPU usage over time, you’ll find that Microsoft Edge uses less CPU. 

Other browsers like Firefox or Opera when performing similar tasks such as opening new tabs or switching between tabs tend to use more.

This is because Microsoft Edge has been built with a sleeping tab feature that minimizes resources when you are not using those tabs. All in all, each browser can be made to consume less CPU when you practice resource-saving tips. 

If you are looking for a lightweight browser that won’t take up too much of your space, we have reliable recommendations.
