Apple already acknowledged the issue, and now they are offering a free battery replacement for such devices. For getting the free battery replacement one simply has to go to an Apple Store or Apple-authorized service provider. The most common models that were affected by this issue were Macbook Pro 2016 and 2017 models, both with two and four Thunderbolt 3 ports.
To make sure that you are facing the same issue and will be eligible for the free battery replacement, check if you are getting a Service Recommended status shown on the battery health. To check simply go to Apple menu > System Preferences, click Battery, click on Battery in the sidebar, and select battery health. In the older Macbook Pro, you simply need to hold the option button and click on the battery icon on the top right.
The issue came after an update to macOS Big Sur 11.2.1 or the latest supplemental update of macOS Catalina 10.15.7.
