Some macOS 12.2 Users Experiencing Bluetooth-Related Battery Drain Issue During Sleep Mode

Apple released macOS Monterey 12.2 earlier this week, and some Mac users who have installed the software update are experiencing excessive battery drain during sleep mode, seemingly due to Bluetooth accessories frequently waking the computers.

The issue has been reported by users across the MacRumors Forums, Reddit, and Twitter over the last several days, but it is unclear how widespread it is.

Affected users say their Mac's battery life drops from 100% to 0% while in sleep mode overnight since updating to macOS 12.2. A few users tried to identify a cause in Terminal and found that Bluetooth accessories are frequently causing a "DarkWake from Deep Idle" that results in the Mac repeatedly waking from sleep, which drains the battery. The issue appears to be affecting both Intel-based Macs and M1-based Macs.



Users report that the issue ceases when Bluetooth is disabled or when all Bluetooth accessories are disconnected from the Mac, but this is not an ideal solution.

Apple seeded the first beta of macOS 12.3 earlier this week, but it is not immediately clear if that version fixes the issue. We have reached out to Apple for comment on the matter and will provide an update if we hear back.

So does Monterey include any useful improvement or feature? What I know are full of bugs and meaningless changes.
The new ‘Autodrain’ feature enables apple users to decrease their battery health to allow them to buy a new macbook sooner than normal

This is what is going on with Apple. The only difference is it's the "Software Team"

Monterey is such an unbelievably huge hunk of garbage. I keep waiting for a major release that fixes all of the bugs I have with it (on my $4k laptop no less) and it just keeps getting worse. But at least we have a host of idiotic new features that Apple can advertise to the short attention span crowd. Glad I have a notification center I can't turn off while the stability of my incredibly expensive premium flagship computer is just ruined

It doesn’t seem like MacOS is advancing. It seems like every year they’re breaking things that used to work then spend the remainder of the year trying to fix them. Then the next version of MacOS comes out and the merry-go-round starts spinning again.
