Fake/insufficient Sleep modus

Question

Fake/insufficient Sleep modus

My 2020 MacBook Pro (macOS BigSur) breaks all expectations I have from a properly designed sleep mode:

power consumption is far from negligible; the battery drains by at 20-40% overnight, sigh
activity and network communications are not shut down at all; I still receive notification sounds from messenger services long after I put the MAC to "sleep". That really makes me very uncomfortable.

Is there no "real sleep" mode in a MACbook ? Any settings I can or need to change ?

And this also happens when no USB devices are connected (see related discussions in this forum).

Thanks!

Turn off Power nap and related get-work-done-while sleeping settings

disable wake on network access

disable file sharing

connect your power adapter when you Mac is stationary -- your Mac uses smart charging and will NEVER over-charge.

Something is going wrong on your Mac, we don't have the issue.

Check your Activity monitor. Sounds like some process is running amok.

Yes, four people mention it. Quite a worry. Try quitting apps and see if you can narrow down what's causing WS to run hotter than it should.

Thanks for your reply.

It seems to be the WindowServer, which other folks struggle with as well and no solution seems in sight:

How very disturbing that Apple has posted no fix yet.

Thanks a lot !

The only active option (from the ones you suggested) was:

"Enable power nap while plugged into power adapter" (I would have never interpreted this one correctly!)

I disabled it and will now monitor the sleep settings.

I still will disconnect the power adapter overnight while I test how much power is consumed in sleep mode.

Update: nothing has changed, the MacBook "woke up" several times in sleep mode. One time could be clearly tied to a bluetooth device in its proximity. And the battery also lost significant charge overnight, sigh.

I find this highly unsatisfying and disconcerting. I definitely want a full sleep mode, without having to go through dozens of settings that are on by default.

This issue is actually driving me a bit crazy. The full (!) battery drains overnight in sleep mode when the MAC is supposed to not do much. How do you all live with such a blatant flaw? How do you not lose complete trust in macOS ? And in what sense would you claim that macOS is superior to the much ridiculed Windows OS ?
