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

Same, I have a MacBook Pro 2019 and it drains every night, no matter what I do. It drains all the way, too, not to 3%. I've run the activity monitor, shut down background apps, closed down all the apps running; it doesn't matter, it still does it. It's destroying the computer too because I'm currently in a very hot area and when I carry it in my bag and then take it out after a few hours, it's so hot I almost can't even touch it. Then I open it and it's really glitchy and takes ages to return to normal.

I think it's a built-in design to ruin the machine and battery faster that way we have to buy new ones every few years. It's really unfortunate too because it's a nice machine otherwise.

I'm sure people go through the common points, I sure have. Shut off the bluetooth, wifi, make sure there are no other devices attached to it, make sure everything is updated, reset the SMC and NVRAM, make sure the battery health is ok, etc. It still does it, every time. There should be no reason one need manually turn the machine to sleep mode just so it will go into sleep mode. The battery settings themselves should also be such that sleep mode actually works.

<< and it drains every night, no matter what I do. >>

What you do to prevent that is to connect the charger when you set it down in one place at home. Then regardless of what wild adventures it has at night when you are not around, it will be ready-to-go by morning.

When someone complains that their foot is hurting, your suggestion is to wear shoes, wherein you explain sarcastically that the foot isn’t designed for the rough terrain of city landscapes? Thank gosh you stopped by, here on Apple’s forum. If only I had thought to plug in my machine.

Same for me. I am curious to know if this is happening for Intel MacBooks only.

My MacBook is of 2020 and this issue is persistent since 2022. My original battery went for a toss in 3 years time. I had to replace it in Aug 2023, but no success.

NOTE: Every night I do a complete SHUTDOWN assuming sleep mode might not be enough, but its still the SAME. Even after shutdown, I keep observing the system where it keeps on heating up.

Here are few instances which clearly shows the drainage.

My Battery Settings:

There are many with ideas here that it is normal for a MacBook to drain its battery when not in use or that MacBook is intended to be used powered all the time, etc.. All these ideas are ridiculous since I have a MacBook Pro which is 12 years old, it has original batteries and it keeps its power for months (maybe half year) with a minimum loss of power of 1-2%. So it is just to accept the obvious that Apple has became a poor quality producer with inflated prices. I am not going to buy a new Apple.

I already answered your DIRECT question, but I repeat here: I don't have Microsoft Exchange, Word, Excel or any other Microsoft application. I use Matlab, LibreOffice and Synology drive, nothing else. I saw that you use the expression "fully shutdown" when the computer is shut down. I expect that the Mac has only ONE type of shutdown, and Apple or any other software installed on the Mac should not start my computer during the night when I sleep, and drain my battery. Thank you for your kind help.

Yesterday, I put the MBP to sleep, which is usual. At 14:11:30 yesterday, I wasn't home, so the MBP was sleeping, plugged in. At 00:02:28 around midnight today, the MBP was sleeping too, plugged in. What might be those two power events?

sudo pmset schedule cancelall

didn't appear to cancel these two power events.

Well no, I am not a frustrated MacBook user, rather quite satisfied macOS user...I only asked a question, that's all. I use the MBP mostly for home office, image editing and some such stuff. As I don't carry the MBP to cafes and whatnot, I'd most probably buy a MacMini in the future. 😊

This is a good idea. I also use Mac Mini sometime and it has very good performance, is completely quiet, no problems with batteries, keyboard or displays, which I can change. I don't know why but the Mini is more performant on Matlab than an equivalent MBP with the same processor. My frustration is on other levels: (1) there are a lot of expectations about AI from companies like Apple but as everybody can see from this discussion group the company is not able to fix a rather insignificant battery error. AI and Apple are way away from each other. (2) Even if the software on my Mac is licensed and it belongs to Apple, I own the battery and the computer hardware. As an owner, according to juridical definition, I have the right to exclude other entities from using my property. I express this exclusion by shutting down the computer. But the computer starts when I sleep and uses my batteries without my permission and Apple cannot explain how this happen and who is the intruder. A wrong moral compas.

You own the MacBook, so when you shut it down, it should stay shut down. But, even without Apple intervening, the battery would drain a bit while the device is shut off. But, that someone else is starting your device is somewhat daunting, even if that is Apple servers themselves. Anyway, I think there's way to stop this, even though it might be using just a bit of power, disconnect the internet connection, wifi in the device or the router, or both. But, that's a headache.

By the way, do you pull the plug off your MacMini when it is not in use?

Any device can be attacked from the internet.

Disconnecting the physical connection to the internet is un-necessary and not an appropriate reaction to this issue.

So, what might be the solution/reaction to this issue? By the way, when I put the MBP (or any computer for that matter) to sleep/shut down, there are no 3rd party apps running in the background. Usually, all apps, after being used are shut off.

<< Any device can be attacked from the internet. >>

That is just not correct.

Your computer's actual IP address is NEVER sent onto the internet. Your Router uses its own Internet-visible IP address to "act as your agent" on the internet. This feature is called Network Address Translation.

When your Mac is connected behind a Router you control, any unsolicited responses coming from the internet toward your computer are discarded by default. Only responses to your Direct queries are passed through to your computer.

<< What is the issue you've found with Microsoft Exchange? >>

one of the TIMERs set up to go off in the middle of the night to wake up one of the readers Macs had a task name that suggested it was part of Microsoft Outlook. This one:

'com.apple.alarm.user-invisible-com.apple.calaccessd.travelEngine.periodicRefreshTimer

that appears to be set by Outlook Calendar feature, to synchronize calendar information in the middle of the night.

... but that lead is rapidly going stale because other readers are reporting wake-up problems without microsoft packages installed.

I asked around. This is the reply I got.

Yes, a computer can still be vulnerable to attacks from the internet, even if it is behind a router that uses its own public IP address. The router acts as a gateway between your local network and the internet, and it typically employs Network Address Translation (NAT) to manage traffic. 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.

Certain ports are commonly targeted by attackers because they are associated with specific services or applications. Here are some of the well-known ports that can be vulnerable if not properly secured. Port 21 (FTP): Used for File Transfer Protocol. If not secured, it can allow unauthorised access to files: Ports 21, 22, 23, 25, 53, 80, 443 and 3389. I don't know much about ports, but that's the reply I got.
