The screenshot above (sorry, it is not English ! 😅) shows that my battery has been draining while my Mac was on sleep mode. How can I fix this problem. I would expect for my Mac to lose 1 to 2 percent of its battery throughout a night in sleep mode. Is my expectations just too much ?
Got a tip for us?

Leave it plugged in at night. It's probably doing some indexing since it's new.
Looking at the bars that represents "Screen on usage"... Are you sure it's going to sleep? Maybe turn on Screen Time to see what apps are being used. I know there's another way but I can't think of it now. I'm sure someone here knows it.

macOS does a lot of tasks after it is first run. You are probably seeing the battery run down because those tasks ran while it was sleeping. Recharge the MacBook and do the same thing in a few days and the problem should be gone. If not, there are many posts here about troubleshooting battery issues.
Hopefully it's just new mac indexing that they might allow to happen while in standby.
However, if the issue persists, you can get a bit of a readout of what's causing it by typing this into the Terminal
pmset -g log | grep -i "wake from"
If you end up finding a lot of Darkwake entries referring to perhaps wi-fi and bluetooth then there might be some connected device that is misbehaving, for example.

There are multiple different reasons that cause the Mac battery to drain fast. However, to fix the problem, you can try the below fixes:
1. Restart your Mac
2. Install the latest macOS updates
3. Check battery usage in System Preferences
4. Reset PRAM/NVRAM and SMC
5. Turn off Power Nap
Hope this will help you resolve the issue!

Mine was losing about 10%+ last night. Keeping it asleep overnight, without any apps on the background. This has been happening for long time, and I have observed it for a while now. The draining rate varies, but usually it's about 10% drain over around 16 hours of sleep time. I also notice that if I left the battery at 100% the night when I put it to sleep, the draining become drastically lessen, maybe just about 1%-3%. I've tried to post it to Apple Support Community here, but didn't get any useful responses.
