What’s the average battery loss overnight on your 16” MBP guys?

0-2% for me, so I’d say something’s wrong.
I left mine unplugged for like 3-4 days sleeping and was at 96%.

I think I lose 3-4%. But I am pretty good about terminating most apps and don't have things like Bluetooth turned on. This is based on my turning mine off for several days at a time. Same config as yours.
I would curious to see if you rate of loss decreases if you sleep the system for several days. For many devices there is sleeping and after some period of time, deep sleeping which shuts down every further.
4% in 9,5h tonight.
It is not linear. Depends on your battery charge %. My experience - the higher starting charge level, the lower battery loss reported.
Things to verify if your discharge is too big:
1. energy savings settings obviously (power nap)
2. share Mac analytics (pref->security&privacy->analytics&improvements)- this was the cause for higher battery drain in my case I believe. I disable it by default on all my machines. It was enabled on MBP16 (Catalina default?)
3. Eventually: allow bluetooth devices to wake this computer - in case you don't use external keyboard/mouse
I still see: "diagnostics_agent" & "hidd" processes in console reporting every few hours. Not sure how to get rid of them (if possible at all)

do u close all apps and turn wifi off too? also did you mean 3-4% overnight or over several days?

left it for 2 days (more than 48 hrs) in sleep mode with BT turned off, but wifi ON, and lost 5%. 100 to 95%.. is this good?

Dude, it’s time to have it changed by Apple. Something is definitely wrong with your 16”
How long is your overnight in hours?
The guy above your comment thinks that it is too much, and that there’s something wrong with the machine. 🤷🏻♂️
Oh, maybe 7 hours?
I don't think it's that big of a deal.
I'm certainly not going into the Genius Bar to have it looked at it.
I'm looking for less stress in my life; not more.
I left WiFi and everything on. Well not Bluetooth but I don’t really use it on my computer. The computer is supposed to be sleeping when it’s closed and in my experience it does.
check your power saver settings and make sure you don’t have power nap enabled. could be that

I'm not trolling. I'm reinforcing your point that this is a major problem that should be rectified by a replacement unit.
It's not, all my macbooks since my 2011 air loose up to 10% overnight.
That's why I keep mine plugged in for the most part, except when I'm traveling.
Very good. Keep your machine and enjoy life as others has mentioned
