While macOS Monterey 12.3 is in the beta testing phase, Apple has launched macOS 12.2.1 for all users with some important security and bug fixes. Notably, that includes a patch for the Bluetooth-related battery drain issue for MacBooks.
macOS 12.2.1 is starting to show up for users via OTA. Head to System Preferences > Software Update to see if it’s available yet for your Mac.
macOS 12.2 patched 13 major security issues at the end of January and macOS 12.2.1 was released today with another round of security fixes. We’ll update this post as soon as Apple publishes the details.

macOS 12.2.1 provides important security updates and fixes an issue for Intel-based Mac computers that may cause the battery to drain during sleep when connected to Bluetooth peripherals.
Meanwhile, those who are running the second macOS 12.3 beta have noticed the battery drain issue was solved earlier this week.
