Thank you, found it. Then this is a bug right? Because the setting should only have influence when the MacBook is plugged in...
Got a tip for us?

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

I believe it should receive traffic even on battery. But the energy impact should be negligible (at least 1% to 3% max discharge for 6+ hours of sleep).
Did you, folks, have any success with this issue? My girlfriend's brand new MacBook Air has lost more than 60% of its battery capacity in less than a day while sleeping. It's veeeery troublesome.

2020-12-28 05:46:44 +0100 PM Client Acks Delays to Sleep notifications: [mDNSResponder is slow(829 ms)]Do you have any idea why
mDNSResponder:maintenance keeps waking the Mac up? Why doesn't it affect any of my M1-MacBook-owner friends' machine, just my gf's?
Yep, that's turned off for her as well. And nothing is plugged into the machine.
Could it be a hardware issue? 😔
Do a complete charge. Then shut down machine for a couple minutes. Then turn on again. Use normal and report back
Perfect. Reason why is my m1 mbp wasn’t displaying screen usage no matter how many restarts or shutdowns I did.Hmm, alrighty, will do! I'll report back tomorrow.
Then I charged to 100% and shut down for 10 minutes and then turned on. Then finally it started working again.
worth a shot! Was driving me crazy...
Following are not the permanent solutions but try them out see if they have energy impact on your gf's MBA.
* Turn off "wake for network access" (I think you have already done this).
* Turn off "automatically download episodes" in Podcast, if your gf is using that. See if that solves the problem somewhat.
* Try switching off the wifi before putting the MBA to sleep.
* Try turning off iCloud services for the time being. Apple seems to be having problem with it. Though I think it should be solved by now. Still, it shouldn't hurt to try it.
Wow, that is mine while screen is on. Something definitely using that computer in background. Chrome installed ?Did you, folks, have any success with this issue?

We can test that malware claim if so ...
I'm sad to report back, that the issue still persists. The battery has lost 19% of its capacity last night. 😔

Nope, I've reinstalled macOS two days ago, and not a single 3rd party app is on that machine now, so I could properly debug the system.Wow, that is mine while screen is on. Something definitely using that computer in background. Chrome installed ?

What does Apple > About this mac > system report > power say for battery condition - or generally?
Have you tried disable wifi before closing the lid? The "mDNSResponder" could be network / iCloud sync related.
Apple should just stop doing stuff while Mac is on sleep. They're doing it, to get more data from you.
Of course always on does need some power - but all the services must 'not' run.
The M1 system is always checking your home area.
Give it a try:
Day 1: Put your M1 to sleep and all other apple devices 'turned off' within your house
Day 2: Put your M1 to sleep and load Apple watch, iPhone, iPad, Homepod etc....
You can see it within the stats, that a 'lot' of stuff is being done on Day 2.
Don't like that!

Definitively not normal, look at mine... I didn't loose a single %. The most I was loosing was 3% during a 8 hours sleep.

try (within terminal.app):It looks good to me.
Code:
ioreg -w 0 -f -r -c AppleSmartBatteryAnd check:
- "AppleRawMaxCapacity" = XXXX
- "DesignCapacity" = YYYY
Dive: X/Y and you have your real percentage > for me it's not the faulty number apple is presenting within it's system report.
Don't forget to disable 'bluetooth'Not last night, but I did disable it now. Will report back in a few hours.
Yep. That looks fine.
It says Normal, just like mine.
"AppleRawMaxCapacity" = 4445
"DesignCapacity" = 4382
Well, that should not be the issue. :/
