Battery drain from Power Events on M1 Macbook Pro

As the title suggests, at least that's what I think.


It's happening few times now, but for months I could put the computer to sleep and after 24/48 hours, it would drain maybe 1-5% (no more than 10%?) but the other day I had enough (don't seem like I'm alone either from what I see online). Left it to sleep for 24 hours the other day from 100% and find it at 44%.


If you do:

pmset -g sched

In the terminal (at least for me) there is two Power Events.

com.apple.alarm.user-visible-com.apple.CalendarNotification.EKTravelEngine.periodicRefreshTimer

and

com.apple.alarm.user-visible-com.apple.acmd.alarm


Does anyone know how to stop them? I did:

sudo pmset schedule cancelall

and it does remove it, but after a shutdown, it's there again in the Systems Information > Hardware > Power. So fed up of this!

MacBook Pro 14″, macOS 13.0

Ventura 13 Power Events - Apple Community


I've gave up giving a S about it and moved on. Most days I just shutdown since turning on doesn't take that long plus with the "Reopen window..." feature you can resume what you're doing in no time. Since when is 30 seconds too long anyways?


But yeah when I do

pmset -g sched

I occasionally still do see one or two (sometimes three) Power Events, but as you read the other thread, it's caused because of widgets and such.


So shutdown by night, and during the day I use the MBP, when I have to step away for lunch or gotta head out to pick up the kids, I put it to sleep (with it plugged in all day). Just yesterday the Optimized Battery Charging feature FINALLY working again all of a sudden. It worked for months when I got it, then it stopped working in the end of Monterey through Ventura. Reading from here or there people say they turn off Screen Time, but whatever I don't know if it needs to be on in order for OBC to work, but so happy it's working again.


I was so frustrated before waking up to seeing the MBP lost 9%. For me I unplug during the night because I have it plugged in all day. To me it makes sense this way, but people have told me that's wrong. I really wish there was a toggle that just put the macOS to a complete sleep mode without any wakes. But maybe people are right about not to keep anything plugged to the MBP when it's not in use cause I do have a thumbdrive, SD card, and monitor plugged in always..

I have the same problem, but less battery drain. I think you got more "wake reason".

Try this and you see all events:


log show --last 5h --style syslog | fgrep "Wake reason"


My macbook pro m2 wakes almost every hour....

Interesting, but not surprised. I didn't do anything special to my mac so it's Apple settings doing it, knew it from the start, but again, just wish there was a toggle that puts the macOS to complete sleep with no wakes for anything. In the Battery settings under Options, I have the hard disk to sleep "Always", and Wake for network "Never", and I would imagine that should mean what I wanted above, but nope.
