Two weeks ago, Apple rolled out macOS Monterey 12.2 update on all compatible MacBooks. This update especially allowed users of a MacBook Pro 2021 to take full advantage of the ProMotion 120 Hz screen. Safari, the default browser integrated into the machines, is now able to display the content of web pages with a frequency high refresh rate.

The update also inevitably contained a series of fixes. Unfortunately, installing the firmware was accompanied by the appearance of a bug on some MacBooks, including the 2021 MacBook Pros. According to testimonials that have appeared online, computer battery drains extremely fast since upgrading to macOS Monterey 12.2.

Apple fixes MacBook Bluetooth bug with macOS 12.3

Apparently computers in sleep mode were constantly being “woken up” by intermittent Bluetooth activation. According to testimonies, the Bluetooth connection started to absorb more energy than usual. This failure contributed to draining battery life while MacBooks were idle. This is only the case for machines paired with accessories, such as mice, keyboards or headphones.

Ultimately, users who leave their machine on standby during the night, and during their sleep, found an unloaded machine when they woke up. If you’re used to plugging in your terminal at night, you probably haven’t noticed anything. To check if the Bluetooth consumes too much battery, you can go to System Preferencesthen in the section Drums and consult usage history.

In the meantime, we advise you to cut the Bluetooth connection of your MacBook if you leave it on standby.
