Hello there Benjamin_Elliott,

Thank you for using Apple Support Communities!

I understand that you are having an issue with the battery in your MacBook Pro draining quickly. I am more than happy to help you out with this.

Before beginning any troubleshooting, please be sure that you have a backup of all of your information. To do this, check out this article:

While you are using Zoom and have your accessories plugged in, take a look at your Activity Monitor to see what may be drawing the most power. For more information on Activity Monitor, along with steps on how to access it, check out this article:

To troubleshoot, I would recommend resetting the SMC and NVRAM on your device. For more information on what this involves and how-to steps, check out these articles:
