MacBook Air M1 battery drain - anybody else...?!

That's basically why I asked what I asked; because my first thought was that there's something preventing your computer from actually sleeping.
So the usual suspects are that the computer doesn't go to sleep automatically, that it wakes up for network access or for power nap-features.

Ok, as you may see by my ex posts I used to lose half battery life in allegedly sleep mode on this MacBook Air (restored from time machine backup). I tried to uninstall Chrome (which I frankly don't think was responsible for it), and I more importantly started a new Mac OS user and transferred there all my apps from the old one.
It seemed to do the trick. MacBook Air now lost 0% of battery life during 5 hrs of sleep (I put it into sleep manually before closing the lid as you suggested).

Chrome is a known battery killer on the M1, mainly because of its background updater that seems to ignore its own settings. That's why a lot of Mac users switched from Chrome to either Microsoft Edge or Brave - same core engine as Chrome, but without the hit on battery life.
0% of battery drain after 20 hrs of closed lid (sleeping).
I'll try reinstalling chrome now (M1 version of course).

So update!
I got a new M1 MBA and the battery difference is much better!
Regular light Browsing for with 1 nit under half brightness I got 6 hours with 60% still left. This is with 8 Tabs open in Safari, doing Powerpoint and a Hour of Zoom.

Keep in mind your full charge capacity reading is not going to be a static number. It will rise and fall day to day etc. Don't get too hung up constantly checking Coconut Battery. That isn't the all in all, as to the health of your battery.
With my last laptop it was hanging around 95-97% and I only had It for a couple weeks with maybe 10 cycles
Why are you so obsessed with the guesstimate that is battery health percentage? Is the new M1 not working right?
zero battery consumption after 20 hrs of sleep (with chrome reinstalled)
After few days of normality my MacBook Air started again to drain in sleep mode,
from 79 to 67 percent during the night is quite a lot.
In Activity Monitor I could see that apps like Boom where preventing Mac to sleep.
So I quitted Boom (a sound equaliser app) and tried again.
Uselessly. I maybe should uninstall it?
Are you guys still experiencing drain?
I don't know what to try anymore.

If you are experiencing these problems you should as a first step do your best to force your Mac to go into, and stay in, sleep:
If your Mac won’t go to or stay in sleep
Check your sleep settings, Bluetooth settings, sharing preferences, system activity, and other possible causes.

I have a Macbook Pro M1. MacOs Big Sur 11.2.1. Every night the Mac would lose about 1% battery every hour. I tried all the recommended steps - changing pmset settings, changing power settings in System Preferences, change bluetooth wake settings, etc. but nothing changed. I used the migration assistant so there were leftover pieces from my previous Mac.
Viewing "pmset -g log" showed total Sleep/Wakes since boot at over 1000 in just a few hours of device sleep!!
Sooooo...
I went into:
/Library/Preferences/Launch Agents/
and
/Library/Preferences/Launch Daemons/
and moved out all the old third party .plist files, then did the same for
/Users/myuser/Library/Preferences/Launch Agents/ .
Basically all that remained was files from 2020 or 2021. Then I rebooted.
So far, I have had zero Sleep/Wake events during sleep. Battery life is stable during sleep.

I firmly believe that it should be possible to migrate my old settings - assuming I pull my hair out to resolve annoyances for a few days!! And by the way - this problem could easily return with one crap app that installs a bad system wake!
Mine is set up as new. On rare nights, I lose about 1-2% battery. Most nights I lose 6-7%, if I close all the running apps.
Ok. I have noticed that the keystone plist files in launch agents and launch daemons seem to cause excessive wake events. But on a vanilla system it’s really odd.
What do you see for the sleep/wake count with:
pmset -g log
I really think that wake events are at the center of this issue. And it seems like they occur because of plist/config files in the folders I mentioned above.
I am not sure how to read it but mine says:
Total Sleep/Wakes since boot at 2021-02-14 13:29:44 +0100 :8033
I have put it to sleep 12 hrs ago and it lost 1 percent per hour. Don't know how many times it woke during this time but the log file that Terminal displays is huge.
