MacBook Pro is draining battery while it's turned off - Battery discharges 30% overnight

I have a 2021 M1 Macbook Pro, Most of the time I used it with the charger, and from time to time I let the mac to run out of battery, maybe about a month or more I realized the battery started to drain faster than it usually does, and a couple of weeks I realize the battery drains even when it's shut down.

When computer is power-off it drains about 30% every 6-9 hours. It seems like the computer never has turned off and is still working (and discharging the battery). It occurs when either the computer is sleeping or powered-off.

The battery has a normal condition of 92%. I have tried things such: running the apple diagnostic test (no problems found), disabling the background apps, turning off all the improved battery functions, activating the saving energy functions, I turned off Bluetooth and wifi before turning off the Mac, disabled non-native software such Microsoft Office, I even reinstall the latest macOS operating system (Sonoma 14.0) Nothing is working, the problem persists.

Did anyone had the same problem? If yes, Did you solve it? How did you do it?

Make sure to disconnect the power adapter and all physically connected external devices prior to selecting "Shutdown" since disconnecting items from the laptop can trigger the laptop to power back on. Also avoid touching any key on the keyboard or even the Trackpad since that can also trigger the laptop to power back on. Apple loves to include very useless & annoying features these days.

Before powering off the laptop, make sure to press the Caps Lock key so its LED is lit. When the laptop is completely powered off, this LED should go out so at least you know the laptop reached a power off state and did not get stuck closing down macOS.

Edit: The laptop can be triggered to power on if the lid/sleep sensor is triggered as well. Sometimes this is triggered by moving the display, or even by moving the laptop to or from a metallic or magnetic surface. A bad or misconfigured Lid Angle Sensor could be at fault too, although you can check if this sensor is working by logging into macOS, then closing the lid. Slowly open the lid and peer inside to see whether you can see any video....if you can, then this sensor is not working. Normally you should be greeted with a login prompt as well unless you have the laptop configured to automatically log in.

I have been battling the same issue for some months now on my mac book Pro 2021, mine drained to the extent that I could not power it up, even when I plug it in with its charger, it refuses to come on until my repairer open it up and disconnect something before it comes on, that was when he noticed that the battery drains even when shutdown to the point it wont come on again.

he later noticed that the rate of discharge reduces when the speaker is disconnected from the board, that is, it usually takes a day and half for the battery to drain to zero, but with the speaker disconnected, it now takes about 2 days or more...... I have been using it that way for a month now....... i came to a conclusion that something is actually keeping the laptop awake even though you shut it down, I'm not sure if its a hardware or software issue, but i will lean towards the software side.

I'm not a native English speaker but I think that the correct expression for this could be "misery loves company", we say " mal de muchos, consuelo de tontos".

I'm not sure if it is software or hardware problem. What I can tell you is that if you have the possibility to disconnect the battery and plug-it again, do not turn-it on, the battery won't drain during the night. We made that test. In my case, once the computer gets completely powered off (battery disconnection) and reconnect it without power ir again, the battery remains with its original charge level.

I almost sure that is a software issue on the base hardware (logic board, etc.). I don't know how to solve it.

I've looking for a downgrade for Mac computers but what I found was almost nothing (my original idea was restore de operating system to the previos version to see what happen), but by doing that apparently do not restore de firmware.

It's very frustrating and disappointing, because "it is a Mac PRO" and it cost a lot of money (at least for me)

Vamo arriba!

<< disconnect the internet connection, wifi in the device or the router, or both. >>

The evidence provided so far suggests that internal wake-up timers may have been set on your Mac by software already running on your Mac, or your Mac never went to sleep to begin with, in some cases because of software already running on your Mac.

Your Mac can not be awakened or attacked from the internet, even when it is fully awake. Disconnecting the physical connection to the internet is un-necessary and not an appropriate reaction to this issue.

It looks like the battery is dying, for some reason. I suppose, it would be best to get it evaluated

Yes, better check with the technical service.

<< Any suggestions would be very welcome. >>

if you plug it in before you set it down for the night, it can't run out of power no matter what it is doing.

You should answer my DIRECT question.

Do you have Microsoft Exchange app installed on your Mac?

it is usually installed with Word and Excel? do you have WORD and Excel?

Thanks for your replay. I've been observing this issue on my laptop and I've discovered that even if the computer is turned off (after a shut-down), it is still detecting as if it was connected to the power outlet.

Is pretty strange, isn't?

Hi chdsl, thanks for your reply!

I will try your commands and I will see what happens tomorrow.

I ran a Diagnostic tool on Mac and it has thrown me that there may be an issue with the accelerometer or gyroscope (IMU001).

The warranty has expired few months ago :(

I will inform you tomorrow if something happens with the shutdown option

Regards,

Andrés

Hey chdsl, the problem persists. When the computer is powered off, it still drain energy.

I'm almost convinced that this is a hardware issue. I would have to take this device to the service.

Thanks for your replies.

I have the same issue. Battery totally discharges when switched off. Thought it was the battery even though it said it was good. Changed it anyway costing me £140 and its still the same.

Something is clearly not right with the OS to cause this.

Must be something running in the background draining the battery.

Any suggestions would be very welcome.

Hi Dodo_ I'm sorry for the delay on my reply.

I didn't find any solution.

I have de feeling that this issue was caused by an OS update. As far as I know, Apple updates hardware and software at the same time, and this probably caused this problem.

I will try again reinstall the original operating system to see if this issue gets solved.

I'm sure this is a software issue at hardware level (programing the software that control the hardware) and not an operating system software issue.

Please, reach me if you find any solutions for this.

Have a nice day

Hi All,

I am having the same issue, MacBook pro 21 continued to use energy while it was off not sleep as seen at the picture below.

Has anyone tried with Apple service yet and what was the result?

Thanks.
