macOS 12.3 still has a battery management issue behind it that can affect any of Apple’s processor-based laptops, says a communication made to Apple technicians. The battery drains despite the Mac being powered.
The document, published after the release of macOS 12.3, was not amended with 12.3.1. He describes a case where the user finds that his MacBook Pro/Air drops his battery charge from 100% to 90% even though the machine is powered on. Then the battery goes back to 100%. Other situation, the Battery Status menu shows “ No charging in progress “.
This behavior is known to Apple, which is working on its correction, the sheet indicates. And contrary to what one might think when reading the first description, this back and forth between 100 and 90% is not linked to the Optimized Battery Charging function (which would rather go down to 80% ). The document exempts this function and enjoins Geniuses not to recommend that customers disable it.
macOS Big Sur: an option to force an immediate full recharge
To preserve the battery of MacBook Air and Pro, macOS 10.15.5 manages charging better
