How do I reduce Zoom power usage?
1. Close unused applications
If you’re having trouble with Zoom’s CPU usage, it’s a good idea to close any other applications that may be open on your computer.
You may be running other resource-intensive applications while using Zoom on your Mac, Chromebook, or Windows 11. If possible, close out any applications that might be using a lot of RAM or processing power such as Microsoft Word or Excel.
2. Update Zoom/browser
The first thing to check is whether or not you have the latest version of Zoom. If you’re running an older version, you need to update your software. Zoom browser 100% CPU tends to occur when running outdated programs.
In the event that you are using the web version, you need to update your browser to the latest version to avoid missing out on new features or experiencing limited functionality. This applies to all operating systems from Windows to mac.

The lower the quality, the less processing power it uses. If you’re having issues with high CPU usage when using Zoom, try lowering the video quality first. It may also help fix issues withZoom crashing when screen sharing.
