You have an unusual situation with the Not charing message when plugging in the Macbook charger. Why is that, let’s explore this feature with us.
In fact, this feature has been around since macOS version 10.15.5. It was developed to help Apple manage the battery health of MacBook devices more efficiently, maintaining a longer lifespan. However, if you prefer to control the charging status of your device yourself, disable the feature with the steps below:
- Step 1: Open or search for System Preferences
- Step 2: Select Battery
- Step 3: Uncheck Optimized battery charging > Click OK

However, we still recommends that you use this feature to help your battery be less old, more durable over the years. In addition, the Not charing condition also occurs in case your power supply does not provide enough power for the device or you use a non-standard Apple charging cable that does not support USB Power Delivery.
Optimized battery charing only works on devices that meet the Thunderbolt 3 port requirements and run macOS 10.15.5 or later.
If you are a person who has a habit of charging the battery overnight to use the next day, Batterry Health will only charge it to 85%, then stop charging and until near morning the battery will continue to be fully charged. This mode works based on your battery’s temperature history and how you charge your device.
