MacBook Pro 16 battery draining while sleeping

[MrMacuser42]

Hello,
I have noticed that my battery loose around 5% during sleep, but two days ago I noticed something worry for my.
I closed the lid with 28% but on the morning I had only 18 which was 10% less. I found this kind of logs:

There is lot of logs like

Entering Sleep state due to 'Maintenance Sleep':TCPKeepAlive=active

Anyone have idea what could happening?
I have disabled power nap on battery but I have enabled find my mac localization service.

My "broken record, there he goes again!" advice:

Unless there's some reason why you really need to leave it on at night, power it off and then reboot in the morning.
Takes only a few seconds and SOLVES "the loss of charge while sleeping" issue.

I get the same behaviour with my MBP 16 - it baffles me how much power it consumes during sleep.
Like the previous poster says it seems to make sense to shut down the machine if you need the battery life preserved.
I'm hoping Apple will introduce further power nap efficiencies as well as various other bug fixes in upcoming patches.

But I have power nap disabled on battery in energy saver settings. Hm..

Disabling WiFi before closing the lid resolves this drain for me.. a few days in my bag and it will drop maybe 2%.
