How to Make Chrome Use Less RAM and CPU?

You aren’t quite sure why Chrome consumes so much CPU? This guide explains why CPU usage is high and how to keep Chrome’s CPU usage at a minimum.

High CPU usage can be spotted by the following symptoms:

  • I’m having problems with lag/jumping on my screen, especially when scrolling.
  • (GPU or RAM can also be to blame for a frozen screen).
  • Your laptop’s battery is draining quickly (it might also be worn out).
  • It gets hot and the fans start to hum.
  • The majority of the time, things are combined.

Unless a computer has a good noise filter, the noise clue can be hard to detect, but laptops are not shy about it. In this situation, if you are sitting on your lap and you feel that your skin is melting off of your legs, you are probably experiencing high CPU utilization (or bad cooling).

Why is Chrome using so much CPU?

It’s not one variable explanation why Chrome uses so much processing power. There can be many reasons. Many say Chrome is a CPU-heavy browser. You probably don’t have a Chrome problem – rather it is related to the way you use Chrome.

Your browser may use a lot of CPU because of:

  • The number of running applications is too high. You can add browser extensions to your browser to add functionality.
  • Too many browser tabs open at the same time. The accumulated usage can drain your CPU (the brain of your computer), or your RAM (computer memory). It will also significantly shorten battery life — and give you a higher electricity bill.
  • Unless you have an extremely powerful machine, streaming HD videos (YouTube, Periscope, etc.) will typically be very CPU-intensive.
  • A lot of animations on a page.
  • A lot of ads on the page.
  • Watching videos that automatically play (go to hell, seriously).

One of the most common reasons for high CPU usage in Chrome is related to the amount and the type of Chrome Extensions you’re using. As a rule of thumb: when you add more software packages (like extensions, plugins, apps) to a system, you’re increasing your risk of slowing down your computer. Not always – in general.

In addition to browser extensions, as you can see on the list above, there are other reasons for high CPU usage that we will discuss.

If you are experiencing a CPU issue, it is usually not Chrome itself, but what you are doing when using Chrome.

You can almost certainly ease your Chrome CPU problem with one or more of the following tips, or at the very least reduce your total hardware usage. I think that’s fantastic.

As you can see, your Chrome browser uses a lot of CPU to do these tasks.

You can use the built-in Google Chrome Task Manager to find out which Chrome tasks or processes are consuming so much CPU. You can use this tool to see how much CPU or Memory a particular Chrome process, extension, or page is using. You can use this to find malicious web pages or extensions.

Click the three dots symbol in the top right corner of the Google Chrome browser to access the Task Manager application.

Steps for Optimizing Google Chrome

On your browser corner should appear a menu list to which you should select the ‘More Tools’ option and then select the ‘Task Manager’ option as shown in the following  image:

Upon clicking the Task Manager, a window will appear in your Chrome browser that contains details of all the extensions and open tabs, as well as processes that are currently active. It will contain complete information related to each process, such as the amount of memory being used, the CPU usage, the Process ID, and about any network activity that is occurring. You can use the drop-down list to stop a particular process or task in Chrome that uses a lot of CPU power. 

This process should be selected, clicked, and the process should then be ended.

Here, for example, the red highlighted tab consumes the most CPU,  123.1%. As a result, if we want to end this process from Chrome, we must select it, press the ‘End Process’ button, and then click the ‘OK’ button. Your browser will show that the process has been closed.

Disable Chrome Add-Ons using much CPU

Similarly, you can uninstall such Chrome extensions from your browser that use much CPU and other resources. Using the Task Manager, you can determine which extension consumes the most CPU in Chrome. Next, you will need to select ‘Settings’.

Now select ‘Extensions’ from the left sidebar as shown  below:

This window displays all extensions installed. You have to pick an extension you want to remove or disable.

In the following option, you are able to disable or remove the respective Add-On from your browser by using the highlighted options.

Reset Google Chrome

You can also reset your browser to stop Chrome from using so much CPU. Chrome’s settings can be accessed by clicking the button labeled ‘Settings’. Next, make the following adjustments in ‘Advanced’ settings:

Click on the red highlighted ‘Reset and Clean’ option next to the mouse cursor. Here is the link.

When resetting Chrome, all extensions, save passwords, and bookmarks will be erased, except for the extensions you added to Chrome.

By using the tips in this article, we can determine which Chrome task is taking up a large amount of RAM in the browser, as well as how to get rid of them. Chrome comes with a built-in task manager.

Additionally, you found out how to use Chrome’s Task Manager to figure out which web pages and extensions are causing trouble. The Google Chrome settings allow you to turn off or uninstall these kinds of things.
