MacBook Pro 16" not sleeping - Please Help!

[radicalgel]

I've had this Mac on Catalina 10.15.5 for a few weeks now and suddenly noticed this battery drain overnight. It went from 60% to 3% two nights ago and happening last night too. After doing some digging I noticed that com.apple.alarm.user-visible-com.apple.remindd.time-alarm seems to be waking up the Mac every few secs. Googling it says that it's related to scheduled reminders which I have a few of but disabling those hasn't helped either. I've attached a snippet of the pmset log below. Basically these set of lines repeat all night, even when the lid is shut. Can someone please help?

I also noticed that certain scheduled tasks persist in the System Information > Power > Next Scheduled Events even if they've been removed from the reminders app so I'm wondering if this is the issue?

I'm having this exact same issue. Only one scheduled event though, but dated 29/05/2120, 18:00. I just set up this new MacBook Pro 16" (2019) by transferring the Time Machine backup of my MacBook Pro 13" (2016) during setup.

Edit: I just installed the 10.15.5 Combo update, and that didn't have any effect.

I read through man pmset again, and found the command sudo pmset schedule cancelall. That solved the problem. At least so far it seems that way.

Edit: I want to add that after rebooting and later connecting to power, a new scheduled power event showed up. Another com.apple.alarm.user-visible-com.apple.remindd.time-alarm, but this time not set so far in the future. And it isn't accompanied by the powerd process using > 100% CPU.
