How to Fix High CPU and Battery Usage by Microsoft Teams

Trying to fix high CPU and battery usage by Microsoft Teams?

Using Microsoft Teams can be a great collaboration tool for anything that requires planning. Whether it’s a one-on-one project, a giant company, or a university, Microsoft Teams can definitely cater to your extensive needs.

However, it’s a great asset to have until it starts lagging and consuming incredibly high amounts of CPU performance from your computer. At the same, the battery usage is no joke either!

So why is Microsoft Teams acting up like this? In this article, we’ll be going over the possible causes of this problem, as well as the necessary steps you can take to alleviate the issue. Here’s how you can fix high CPU and battery usage by Microsoft Teams.

Let’s dive in!


1. Close Microsoft Teams With Task Manager and Activity Monitor.

If you’ve been restarting Microsoft Teams to try and fix your problem, you’re on the right track. Unfortunately, bugs and processes related to Microsoft Teams can continually run in the background despite the program being terminated.

This can be especially problematic if the bug that’s running is the culprit for the intensive CPU usage. Luckily, you can terminate these background processes using Task Manager. Microsoft developers added the Task Manager as a great way to monitor all running foreground and background apps.

The Task Manager can terminate and end tasks completely, freeing the entire program from your computer’s memory. For Mac users, we’ll be doing this through the Activity Monitor, the Apple equivalent for the Task Manager.

Here’s how you can close Microsoft Teams with Task Manager:

  1. Start by opening up the Task Manager with the hotkeys CTRL + SHIFT + ESC. Alternatively, you can also just search for ‘Task Manager’ in the Start menu and open it up from there.
  2. By default, your Task Manager should open up in full view. However, if you’re missing some features, just move your mouse to the bottom-right corner of your screen and click on More details.

  1. Now, on the Processes tab, click on any random running application and type in ‘Microsoft Teams’. This will automatically locate and highlight the Microsoft Teams process that’s running on your computer.
  2. Finally, right-click the process and select End Task to completely free all traces of it from your computer’s memory.

For Mac users, here’s how you can close Microsoft Teams with Activity Monitor:

  1. Press on the Command + Spacebar keys to bring up the Spotlight search field.
  2. Type in ‘Activity Monitor’ and click on the first result that’s returned from your search.

  1. Now that Activity Monitor is open, look for and select Microsoft Teams.
  2. After that, click on the X icon at the top-left corner of the Activity Monitor window.
  3. Lastly, a prompt will open up, asking you for confirmation. Just click on Quit to terminate the process.

Now that Microsoft Teams and all its annoying background processes have been cleared from your computer’s memory, open it up and test it for lag.


2. Turn Off GPU Hardware Acceleration.

Your graphics card is solely responsible for any visual rendering displayed on your screen. Ideally, depending on your system, your stronger graphics card is reserved for games. Simple applications like Microsoft Teams don’t necessarily need GPU-level rendering.

However, if you’re on an older computer, having ‘GPU Hardware Acceleration’ might make a lot of difference. At the same time, the option is enabled by default on most installations across all devices. Since it uses more of your graphics card, your CPU and battery usage will inevitably be taxed as well.

In this method, we’ll be disabling ‘GPU Hardware Acceleration’ to reduce the CPU and battery usage that Microsoft Teams is demanding from your computer.

Here’s how you can disable ‘GPU Hardware Acceleration’:

  1. First, open up Microsoft Teams and then navigate to the profile icon at the top-right corner of your window.
  2. Now, move your mouse down and click on Settings.

  1. By default, you should be directed to the General tab. Displayed here is a list of features, look for and check Disable GPU Hardware Acceleration.

When you’re finished with these steps, you’ll have to restart Microsoft Teams for the changes to take effect. Before you do so, you can check the next method where we’ll be disabling another CPU-problematic feature.


3. Disable Read Receipts.

Being able to discern when someone has seen your message is a great way of monitoring contacts. Additionally, it’s also an incredibly useful feature to have so you can observe the attentive employees or teammates in your group chats.

However, despite not being a CPU-intensive process, the ‘Read Receipts’ feature has been linked as a prime suspect for the lag. Turning this feature off has helped other users decrease the CPU and battery usage by the Microsoft program.

Here’s how you can disable ‘Read Receipts’:

  1. With Microsoft Teams open from the previous method, click on the profile icon at the top-right corner of your window.
  2. Now, navigate down to Settings.

  1. On the left pane, click on Privacy and look for Read Receipts. You can read more about the feature in the description provided, but don’t forget to disable the feature when you’re done.

Now go ahead and restart Microsoft Teams to check if the CPU and battery usage issue has been fixed. Additionally, you can also restart your computer for good measure.


4. Use the Web App.

With all the methods exhausted above, we’re going to recommend that you try their website instead. Ideally, by accessing their website, the program’s permissions and control over your computer’s processing power should be limited.

You’ll still be able to have most, if not all, the features you need on the web app. The web version supports video calls and group meetings so you won’t be missing anything from that technical side.

This can be a temporary solution while waiting for a Microsoft Teams update to fix your problem. You can access and log in to their website here.


5. Update Microsoft Teams.

By default, Microsoft Teams should update automatically in the background. Though this could also be the reason for your problem, we doubt that this is the case. The application doesn’t require a lot of CPU performance to update. Furthermore, the software updates aren’t large files and typically finish downloading in minutes.

We still recommend manually updating Microsoft Teams whenever you can. This way, you’ll be able to get the latest version if one is available.

Here’s how you can easily update Microsoft Teams:

  1. Go ahead and open up Microsoft Teams and click on the profile icon at the top-right corner of your screen.

check for updates

  1. Scroll or move your mouse all the way down and click on Check for updates.

Microsoft Teams will automatically look for updates on its own and update itself in the background. If an update is available, this should have a big chance of fixing the problem.

Now that you’ve reached the end of this article, we hope to have helped you fix high CPU and battery usage by Microsoft Teams. If you have any questions regarding the methods above, feel free to leave us a message in the comment section below.
