Apple released an official support document on July 31 explaining the reason for the 'Not Charging' message when connecting a laptop Mac to a power source.

This happens with MacBook series models that have a Thunderbolt 3 port and have macOS 10.15.5 or later installed. macOS 10.15.5 includes the 'battery health management' feature that reduces battery degradation and extends battery life, and this phenomenon also occurred due to its fine control.

Apple says, "Depending on its settings, your Mac might temporarily pause charging to help calibrate battery health management, a feature designed to improve the lifespan of your battery". Specifically, it states that when the battery health management option is turned on, it will show 'Not Charging' and the battery's maximum charge level may be lowered temporarily.

This is normal, and it's how battery health management optimizes charging. it will eventually return to 100 percent, depending on your Mac's usage.

The battery health management feature works based on the battery's temperature history and charging patterns, so if you often leave it plugged in to the power supply after use during the day, it may charge up to 85% and not charge any more until the most frequently used time of day comes in the morning. This is how the action of taking care of your battery can look like a failure to the human eye.

This feature is enabled by default, but if the charge is limited, it may reduce the amount of time you can use your Mac when you're outside. To disable it, from the Apple menu, go to System Preferences > Energy Saver > Battery Health, deselect Battery health management, and click OK.

The 'Not Charging' warning will also appear if there isn't enough power to charge (e.g., you're not using a power adapter or cable that meets the requirements). We recommend that you follow the "if your USB-C power adapter isn't charging your Mac" section of the support document to check for the cause of the charging problem.
