Macbook Pro 13" 2019 power off huge battery drain!

[0906742]

Seems like my MBP battery is dead only after about 50 charge cycles.
It has been doing in past couple of weeks that it drains battery about 10% a day when it is POWERED OFF (I never use sleep mode, I always power off when not using it). Up until now it has been draining about 1-2% a day when powered off but now it has increased to about 10x which is ridiculous.

Anyone else seen this happening lately? Could it be some kind of OS issue after all? Anyway I don't see any other way to power off this machine, so is there any way to force it power off and make sure it really is powered off. I don't think pulling out the battery is very practical…

Just hold down the power button for 5 seconds?

Do you mean press the button after powering off it on the OS? Otherwise isn't it going to shut down power while OS is still running (which is usually not suggested)?

Also isn't OS menu power off supposed power off completely? That's how I've been always doing and up until now lately it has not been sucking the battery empty while off. It used to take about 1-2% a day before but now it has increased to 10x. Perhaps battery self discharge rate is increasing?

Dead seems to be an exaggeration, but those are numbers people get with sleep instead of power off, so it is odd. What does System Report say your battery health is?

System reports says battery condition is normal and based on CoconutBattery health is about 100% (sometimes goes just below 100% and sometimes over 100%). Also run time on battery seems about the same as usual.

Yeah, that power off consumption /battery drain is definitely something odd and currently more like what it might be with Sleep mode (but as I said, I never use sleep, I always power off by OS).

I suppose calling Apple wouldn't hurt, though they'd probably say it's within spec as long as the battery is fulling charging.

Totally misleading thread title. Your battery is obviously not dead. It has 100% life in fact. Your problem is supposedly the battery draining while powered off. To which my first question is, are sure you’re actually turning it off?

Good question. How to make sure it is actually turning off? I have been always powering it off by OS menu
selecting shut down (I never just close the lid or choose sleep mode in that menu). It appears power off and when I restart next time it boot normally and take some time. Just like always but now instead of 1-2% drain a day it takes 10%
I also checked system log but there was no entries between my last shutdown and restart today, so looks like it has not been running os during power off...

ps. I edited title a little to avoid confusion.

It’s kind of a force shutdown

It will shut all processes running and you can see how much it drains after shutting down this way.

If there is an actual battery problem you will know.
If the issue is software....you will know.

Pretty sure it's not the way you shut it down, especially given what you've said. Shut down from the menu ends at the same power state as a hard shut down, just gets there more gracefully.

That is my impression too that using shut down from the menu should really power it off, just gracefully. Forcing it "down" by pressing the power button long just causes that OS is not closing running processes and may even cause OS or file system corruption so I'm not very keen to use that option. Not sure if I could try it from some restore screens when actual OS is not running. However since there has not been this problem in all about 9 months I've had this machine and it just started within last couple of week, I'm afraid battery just got weak. I think 9 months and 50 charge cycles is pretty high number for the batteries these days... Since no one else seems to be reporting the same problem here, it is unlikely OS related problem.

It's also possible a physical issue has developed elsewhere in the power system that's causing a leakage. Probably would cost more to figure this out than it's worth, though, unless it gets worse.

In the mean time, since it's not saving you any power to shut down, you can use sleep from now on and get immediate waking!

Or simply one cell in the battery already damaged...

Anyway, the problem is that I don't use my MBP daily, something even weekly, so I've been always powering it off to avoid battery getting empty during storage.

Looks like my MBP battery is back to normal regarding power off battery drain. I just had it turned off for 8 days and it lost about 6% only. I did not do nothing or changed any setting but installed the latest minor OS update released in last couple of weeks. Was there some OS bug or what (?) but that is the only thing I did and it seems fine now.

When the problem occurred TWO times in a row, I had installed bigger OS update that was released just before the last one (I been going thru pretty much all updates as they have been released, so the "big update" I was referring to was not from Mojave to Catalina or something as big, just one of the incremental updates they release regularly).

 

[0906742]

Regarding all this, I'm curious how much battery drain in percentage other see when their MBP is powered off? How much it is in 24 hours or certain longer period of time?

I'm having the same problem with a 2019 MBPro 13". The battery has been showing 100% at the end of the day (expected, since I work on a Dock). Cycle count: 51, Condition: Normal, Full Charge Capacity : 4651mAh

I use Apple --> Shutdown, wait for the keyboard light and Touch Bar to go dark, then close the lid and put it away. The battery will be completely dead by the next morning.

Same here but with MBP 2019 16". Cycle count: 62, Condition: Normal, Full Charge Capacity: 7629.

Update: Last night I did not shut down. Instead I put lid down so it sleeps. Battery status was 91%. This morning when I opened lid, battery status was 61%. Previous night when I shut down it was 100% and when I powered on next morning, it was 1%. This is bewildering because I would expect opposite to happen, i.e. more drainage when powered on. Have attached screenshot of Battery settings in Sys Prefs.
