This is normal macOS behavior — there are a few reasons a brief not charging blip appears even with a working charger:

  1. USB-C Power Delivery renegotiation USB-C chargers negotiate power contracts with the Mac. Any tiny handshake interruption (cable flex, adapter settling) causes a brief not charging pause (~1–5 seconds) while PD re-negotiates. This is the most common cause of a single-sample blip.

  2. macOS battery health management “Optimized Battery Charging” can temporarily pause charging between charge cycles, briefly reporting not charging before resuming. More common near 80%, but can happen at other levels.

  3. Loose connector A MagSafe or USB-C connector that’s slightly unseated can cause momentary drops and recoveries.
