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 found another forum on the Apple community which discussed exactly the same issue in 2022 related to wakeup events on Mac which were draining the battery. This other forum went on to discuss in vain different solutions until 2023. No explanations from Apple on this other forum. The forum tested everything possible, no solution. Conclusion: draining the batteries is a function introduced by Apple exactly with this purpose: to drain batteries until the computer is dead. This concludes my participation to Apple forums, I'm going forward with a Linux OS on Lenovo portable. I wish good luck for everyone in finding why Apple is starting your computers without your consent.

I've been using Linux since 2005, and I've been with Windows even longer. I decided to get myself a MacBook Pro to experience macOS. It's true that Apple is primarily a hardware company, so they need to sell hardware to stay afloat, but I find macOS to be somewhat more pleasant than Linux. There are handful of Mac applications that I can't access on Linux or Windows. By the way, Linux can also drain batteries, depending on the specific distribution you choose. Even though Linux is open-source, the major players in the industry still hold significant influence. While we might not refer to Debian or Arch as companies, their committees and decision-making bodies operate much like private enterprises, making choices that we, the users, have little say over.


Since I ventured into the Mac ecosystem for macOS, I can utilise any Mac product, so my next purchase will likely be a Mac Mini. I've already got the accessories sorted, like the Magic Mouse and Magic Trackpad.


At the end of the day, it's your choice whether to stick around or not, but if I were in your shoes, I wouldn't leave.

<< However, if certain ports are open or if there are vulnerabilities in the router or the devices connected to it, an attacker could potentially exploit those weaknesses. >>


Most of those ports are not open by default on a Mac, so NAT Network Address Translation, as you and I both mentioned, provided by a Router YOU control, will suffice to protect you from ordinary anonymous attacks across the internet, which is what I wanted to be sure users understood.


Bad guys can NOT just 'crawl through the wires and hit you from afar'. And nothing can be sent to your Mac when your Mac is off.


The VAST majority of users who find their Mac has been attacked were attacked by software they downloaded AND approved for use. Nothing can become executable unless you provide your Admin password to "make it so". Be vigilant and you will most likely be safe.

Nonsense.


Conspiracy theories are more fun, but Apple has no interest in draining your battery. As I stated very early in this and similar discussions, you can completely defeat that as an issue by plugging it in at night.


This is FAR, FAR more likely to be something introduced by sloppiness or oversight than by malice.

This I agree. I have Excel, Word, few browsers even though mostly use Safari, GIMP, VLC, Geany and some open source (Linux) apps, Find any file app, which I use to find files, and then delete them myself. That's how I got rid of MS Outlook. No cleaners, no VPN and such like. I can't/won't use the macOS Office suite. Most of my work is in the internet, and I even know where the servers are stationed, and who maintains them. Quite safe, really.


But still, would like to know what is this,
