A battery management issue remains behind macOS 12.3, which could affect any processor-based Apple laptop, according to a note to Apple engineers. The battery is discharging even though the Mac is receiving power.
The document published after the release of macOS 12.3 has not changed with 12.3.1. He describes a case where the user finds that the battery charge on his MacBook Pro/Air drops from 100% to 90% even though the device is turned on. Then the battery goes back to 100%. In another situation, the battery status menu shows “Not charging in progress”.
Apple is aware of this behavior and is working on correcting it, the paper says. And contrary to what one might assume from reading the first description, this back and forth between 100 and 90% is not connected to the Optimized Battery Charging function (which would rather go down to 80%). The document exempts this feature and instructs Geniuses not to instruct customers to turn it off.
