Apple releases macOS 12.2.1 fixes some MacBooks draining spontaneously

Along with the release of iOS 15.3.1 and iPadOS 15.3.1, Apple today released the update for macOS 12.2.1. It fixes a bug in the Bluetooth module that activated the connected accessory while it was sleeping, provoking a premature discharge of the MacBook.

Previously, some Intel-based MacBook users complained that the battery drains quickly in sleep mode. In some cases, the battery charge dropped to zero overnight. According to The Verge, users have suspected that the problem is related to the improper operation of the Bluetooth module in sleep mode. However, turning it off in some cases did not lead to any positive changes.

In the patch notes for macOS 12.2.1, Apple says it’s fixed an issue with Bluetooth-connected devices that was overly draining your MacBook’s battery due to an incorrect sleep mode. The company does not give any indication of the existence of such a problem and how to fix it in laptops based on Apple M1 processors.

Also in macOS Monterey 12.2.1, a vulnerability in the WebKit engine that could allow arbitrary code execution has been fixed.
