FYI, I'm on the newest macOS also.
Every few days randomly I would check the Power Events, and I noticed it's never been empty again. Either just one or three, max four I've seen. One Calendar (sometimes not there for me), but the acmd can range from 1-3.
I tried getting rid of Calendar widget also, but I just ended up keeping one M Calendar and said F it.
I don't think I updated my self here but I'm glad my Optimized Battery Charging is working again. From people saying to turn off Screen Time, I left it on and said F it. I'll explain below.
I have the MBP on most hours during the day, even if I step away for lunch or go out to pick up kids (while it sleeps) so if the OS wants to be awake, whatever. And by night I shutdown. I mean, with the "Reopen windows..." feature, plus turning on takes less than 30 seconds, it's not going to be end of the world. My battery have been staying at 80% since Monday so that's really good. I do wish I can put it to sleep and not shutdown because I remember I had it boot for 15 days once, and that was always by night unplugging. But knowing every morning I get -9%, no thanks.
BTW, in another thread someone said they checked the computers at a shop and they all had these Power Events too. So clearly it's on every computer.
I just wish there was a real sleep mode where nothing can wake it up besides the lid open, or some kind of button click on a wired keyboard (when on clamp shell mode). I say this about the wired keyboard because and I think I mentioned this before in this thread that with
pmset -g log | grep -e " Sleep " -e " Wake " | tail -n 50
I see keywords like bluetooth and SDXC (and yes I have a SD card in the slot) so all these are also waking it every 10-20 mins for 4-5 times per hour!! So basically the computer is waiting to expect my wireless keyboard to connect multiple times per hour turning it sleep? That's not cool!
I've yet to try this, but I wonder if you connect a wired keyboard to a computer that's off if it will turn it on? Because for clamp shell style users with the MBP standing up that must suck because you have to always open the lid first.
