M1 MBA waking every 15ish mins and draining battery

In the meantime I found a solution to get rid of the power events. By "I found" I mean actually I found this thread:

Reminders app waking mac from sleep - Apple Community

So I tried it!

Behaviour before the fix:

• "pmset -g sched" reports our beloved friends

[0] wake at 12/17/2022 00:41:44 by 'com.apple.alarm.user-visible-

com.apple.CalendarNotification.EKTravelEngine.periodicRefreshTimer'.

[1] wake at 12/17/2022 19:23:54 by 'com.apple.alarm.user-visible-com.apple.acm

• "sudo pmset schedule cancelall"
• "pmset -g sched" -> all good!
• put Mac to sleep
• wake it up by keystroke
• "pmset -g sched" -> bad again

Now the fix:

"sudo pmset sched cancelall"

AND

"sudo chflags schg /Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist"



"This prevents the system from updating the file and my MacBook no longer wakes to reminder events. Needles to mention that it prevents all scheduled system events like sleep, power-on and such."



"I recommend removing the flag before a system update:"

"sudo chflags noschg /Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist"



Behaviour AFTER the fix:

• "pmset -g sched" -> all good!
• put Mac to sleep
• wakeup Mac by keystroke
• "pmset -g sched" -> all good and hope it remains as it is...

Will see tomorrow what "pmset -g log" reports...



Good luck to all...

Consulting "pmset -g log > pmset.log", my MacPro running Ventura 13.1 is now sleeping properly (so far)!
No power events scheduled any more!
Observed no side effects!

I think I found the reason for the battery drain of my MBP 14". I uninstalled AlDente Pro and the problem is gone.

Now I have a MacBook that gets charged to 100% all the time, but that's still better than returning to my work machine that has like 3% of battery left after a weekend.

Just wondering do you use Outlook for Mac at all? My Mac was great for ages, then I recently started using Outlook again and these issues re-appeared.

I did used Outlook and did not experienced any problems related to this.
However I dir use a POP3 account and never used OneDrive. Recently, because of better system integration I switched to Apple Mail despite it has some problems/bugs related to attachments...
