MacBook Showing ‘Not Charging’ When Plugged In? Apple Explains Why

If you’ve noticed that your portable Mac sometimes claims that it’s “Not Charging” you aren’t alone. In fact, it’s happening to enough people for Apple to share a new support document about the situation.

The situation seems to be related to macOS 10.15.5’s new Battery Health Management feature that will mean the Mac stops charging its battery in an attempt to try and ensure that it lasts longer in the long run.

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.

If you notice that your battery isn’t charging, it’s nothing to worry about. Apple also notes that you can expect the normal recharging behavior to return eventually, with timescales depending on the usage of the Mac in question.

When battery health management is turned on, you might occasionally see “Not Charging” in the battery status menu of your Mac, and your battery’s maximum charge level might be lowered temporarily. This is normal, and it’s how battery health management optimizes charging. Your Mac resumes charging to 100 percent depending on your usage.

Apple is trying to ensure that the built-in batteries inside Macs live to a ripe old age before they need to be replaced. Part of doing that is the new feature that will try to prevent a battery spending too long at maximum capacity – something that’s known to cause premature aging. However, while Battery Health Management is enabled by default, it can be disabled. We’d suggest leaving it well alone, however.
