Battery Drain Monterey 12.5

Update to the latest software.

Always make sure your MacBook is using the latest version of macOS. If you’re connected to the Internet, macOS automatically checks for software updates every week, but you still control when the updates are installed. To confirm that you’re using the latest software, go to the Apple menu and choose Software Update.

Optimize your settings.

Energy. The Energy Saver preference pane includes several settings that determine power levels for your MacBook. Your MacBook knows when it’s plugged in and runs accordingly. When using battery power, it dims the screen and uses other components sparingly. If you change this setting to maximize performance, your battery will drain more quickly.

Brightness. Dim the screen to the lowest comfortable level to achieve maximum battery life. For instance, when watching a video on an airplane, you may not need full brightness if the cabin lights are off.

Wi-Fi. Wi-Fi consumes power, even if you are not using it to connect to a network. You can turn it off in the Wi-Fi status menu in the menu bar or in Network preferences.

Applications and peripherals. Disconnect peripherals and quit applications not in use. Eject an SD card if you’re not currently accessing it.

Plug in and power on your MacBook to charge other devices.

Make sure your MacBook is plugged in and powered on when you’re using it to charge other devices via USB. Otherwise those devices may drain the battery in your MacBook faster than normal. If another device is connected to your MacBook when it’s turned off or in sleep or standby mode, the device’s battery may drain.

I have a MacBook Pro 16, and I definitely have a battery drain problem after updating to Monterey 12.5. I know the drill about checking all the settings to make sure they're easy on the battery, but before Monterey 12.5, I easily got a full day out my battery with how I use my Mac. No settings have changed and I'm still using it the same way, and I don't even get a half day out of it now. I just hope it doesn't take too long for Apple to admit it and fix it.

I didn't mean to imply it's affecting everyone. I bought an iPhone 13 Pro Max with iOS 15.x and not long after I bought it, Apple released an iOS update that caused a significant battery drain. It did eventually get fixed. Now I recently bought this MacBook Pro 16 with M1 Max, lots of memory and storage, and shortly after I have to deal with a battery drain issue on that now. It's a little frustrating.

After updating to Monterey 12.5, I too started to see very fast battery drain on my MacBook Air M1. My battery used to last 3-4 days on casual use. Now it doesn't even last a whole day. Also battery drain during sleep is very significant. Like if I just close the lid after closing all the programs at around 25%, my MacBook won't start again until I plug in the adapter. Good to know others are facing same issue and its not just me. Hope Apple looks into this.

Thank goodness I am not the only one who is facing the issue. I thought my battery had a problem and I almost use my warranty to change the battery as I thought my battery is faulty. Now when i read there are people whos having the same issue as me, I am at ease.

There are multiple different reasons that causes the Mac battery draining fast issue. However, to fix the problem, you can try the below fixes:

1. Restart your Mac

2. Install latest macOS updates

3. Check battery usage in System Preferences

4. Reset PRAM/NVRAM and SMC

5. Turn off Power Nap

Hope this will help you resolve the issue!

Yes me too. I have setting up everything as per instruction. I even format my hard disk and reinstall the OS. it still occurs to me. All the steps to fix the issue doesnt work for me at all. Restart? done it. Reinstall OS? done it. still the same and im quite worried as i need to constantly charge my macbook air almost every day. My battery health right now at 96% and its normal but if this keeps on going, im afraid it might decrease and damage my battery. I hope Apple patch this bug ASAP. I already checked if any of my applications prevent the mac from sleep, but everything in place, no application prevents it.

Hello Lameriff,

Does your MacBook sleep when you close your lid? Mine doesn't. If I shutdown my MacBook, it automatically turns back on. Really weird. Looks like I might have to visit Apple store.

My Macbook does need to unlock it once i open the lid back. It does look like its "sleeping" but the battery keeps on draining. i even click the "Sleep" button. still the same. When I shut down the macbook, it does shutdown. its just a sleep issue. everything looks normal when i close the lid like before updating to 12.5 but the battery keeps on draining. Really weird bug.

I’m not experiencing any battery drain issues on my MacBook Pro.

It’s not affecting everyone.

I just realised that my MacBook just won't sleep when I close the lid. Closing the lid does absolutely nothing.

Let's hope all of this is sorted in the next update. Hope Apple actually listens to us.
