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

[Tardegard]

It's been 24 hours since i've seen nub rtc/maintenance. In my second screenshot you see my MacBook Pro really had a good night of sleep. I'm a bit confused because I did TWO things at 9AM yesterday (when it stopped):

• Updated Google Sync and Backup to the new Google Drive
• Quit my VPN app that I left running in the status bar, even if it was disconnected.

I believe the latter to be the main cause after analyzing the Console and seeing the daemon performing stuff during night. (I use PrivateInternetAccess). I'll see if it stays that way.

I also think vpn did the trick

My problem are always Teams, Citrix Workspace, HDB Studio and Cisco AnyConnect

Know what all these apps have in common? Using Rosetta and not being native.

Yep, I think that's it. I've narrowed it down to

• Having Photoshop (2019) opened, or;
• Having Private Internet Access (VPN) running in background.

Both Rosetta.

Yeah if you try using What's App and Messenger via Rosetta your battery just drains dramatically as well, I'm just running web tabs now for them.

Honestly I'm hoping these major apps start getting some updates, for my pro apps I'm only running Citrix and Teams the rest I've migrated everything to work within the Citrix VDI

Teams also is a Electron based app which means that it isn't a native app on the Mac but a Chromium browser page without browser buttons and bars.
Basically it is a website wrapped into a window to look like an app and that makes it sluggish and slow and use lots of resources. And because it is Chromium based it is a resource hog^2.

Hi just wanted to tell you guys that I also had major problem on my Macbook Air M1, in sleep mode as well as everyday usage. I deleted Outlook and Chrome and did a reset of SMC. Now I am having great battery life, up to 10 hours.

 

[Alex W.]

Guess what, you'll always be using rosetta until years and years from now.

That was apples mistake.

Today I saw tons of these:

[archi penko]

M1 max 16" and I have none of those things running. And I left for 1.5 hours, dark screen (brightness down), bluetooth wifi on, no activity, Low power mode, and battery drain 7%!!

I am running Safari, VScode, Screensharing (apple), Notion.

I would expect 1-2% if its really efficient. I find this is not normal...

Nope. Not a mistake at all. They transitioned the same way going from PowerPC to Intel. Eventually they'll take Rosetta 2 away, like they did with Rosetta 1 in Lion. As I recall, their justification to developers was more or less, "You've had plenty of time to convert your software.", and that was the correct answer.

Transitions are hard and take time. But having Rosetta 2 is a feature for now, not a "mistake".

Are you using you macbook in clamshell mode? do you have any USB-C adapter connected when sleep?

Shouldn’t you get 20 hours with the M1?

 

[jdb8167]

Shouldn’t you get 20 hours with the M1?

Depends on what you do on it, display brightness etc.

 

[archi penko]

Are you using you macbook in clamshell mode? do you have any USB-C adapter connected when sleep?

Neither clamshell mode (no external display) or any usb-c adapters.

My issues and problems with darkwakes (and sometimes even full wakes) persist with Monterey 12.3.1, so they haven't fixed anything yet....

Sometimes the issues are with NUB.SPMISw3IRQ nub-spmi0.0x02 rtc/ but sometimes they appear with another "driver code" (the typical you can see in internet from other users)

Even with my notebook disconnected from power, with the lid closed, without any device connected, and even with bluetooth turned off, my battery got discharged from 90% to 75% with nearly a darkwake per minute...

This is my gorgeous battery draining over night:

All my preferences and settings are optimised to avoid such kind of problems...but with no luck at all...

The only solution for me until now it's to use the hibernation feature instead of the sleep one...but that has the drawback of slow wakes... (and in my previous macbook pro 15 I NEVER had this kind of problems, so it's pretty annoying and frustrating)

Ok I think I found part of the problem for constantly wake ups due to NUB.SPMISw3IRQ nub-spmi0.0x02, and incredibly is the network you are connected (or even around you). When I'm at my "home", no matter if you have any device connected or even bluetooth disconnected, the problem persists due to the "network router", for any reason there is a sleep of just 1 or 2 secs following a darkwake of 45secs...

As soon as I left my home and go to my office, such problem disappear and the sleeps cycles last 3790 secs and the darkwakes last 5-10 secs and they are due to different "drivers/reasons" like AOP.OutboxNotEmpty spu_queue_overflow_ep42/ and SMC.OutboxNotEmpty smc.70070000 wifibt wlan WLC_E_PFN_NET_FOUND ARPT so there are some packets or activity in some networks that keeps M1 macbooks awake for some reason. This bad behaviour doesn't happen in non-apple-sillicon macbooks.

Such bad behaviour is with all the tcpkeepalive and ttyskeepwake and location services, etc. disabled at all

You can check here, the exact moment where I left my home and went to my office, so the darkwakes reason and duration change drastically...

 

[ice29]

The initial switch to this behavior can be triggered by the network, but in my case the Macbook will wake every 45s (after it gets into this mode) even with all network interfaces turned off (wifi, BT...)

Please report this to Apple using the feedback app. This kind of specific detail should help them immensely in tracking down the problem.

Who is the manufacturer of your router?

I have found a similar oddity.
Sometimes I can see the DarkWake events starting in the morning at exactly the time I get up and pick up my iPhone. So I've begun to suspect it's caused by some kind of direct or indirect communication with the iPhone.

At first I thought it was due to Focus Mode synchronization, but turning that off didn't change anything.

Are there any differences wrt your iPhone at work or at home? Maybe we can narrow it down.

Folks, I've been reading this entire thread and many others. I also have been cursed 😆 with trying to figure out what's going on with my battery getting drained. I've been on this for 3 weeks everyday trying to figure more of it out 🤦‍♀️

I have the same problem, some nights `SMC.OutboxNotEmpty` hundreds of times, some nights once every 64 mins. I don't seem to experience the `NUB.SPMISw3IRQ` problem

I'm running 12.3.1;
I have;

- sudo pmset -a ttyskeepawake 0 powernap 0 tcpkeepalive 0
- disabled/deleted icloud, plus I don't use and iphone
- turned off handoff, find my mac, all sharing, and all location services
- turned DND/Focus time and all notifications
- turned off my wifi router
- turned off my wifi+bt adapters
- tried clamshell+monitor+usb-c connected, tried lid down all disconnected
- restored defaults and reapplied settings
- rebooted 😆 🤷‍♀️


I have lost 19 battery cycles in March (not representative of my battery usage - I work from home!) so I have resorted to using AlDente and keep the laptop connected with the battery charge caped at 60% to prevent further battery cycles being wasted! For now anyway. and yes, I've tried turning the app off, to no avail.

The main question I'm trying to answer now is in two parts;

A) is there a core macos M1 "maintenance feature" waking the machine kicking off a number of things, OR is that an app or setting trying to do something and the "turning it off" is ignored?

B) is AppleCare able to help at all you reckon?

and.. Additionally:

C) what is mDNSResponder? the culprit or just a first process to "log something"

PID 452(mDNSResponder) Created MaintenanceWake "mDNSResponder:maintenance"

D) why are there many "drivers is slow"

Confirming there are still SMC.OutboxNotEmpty issues with 12.4, upgraded, and reapplied settings, to no avail. I'm going to have to spend hours on the phone with AppleCare? 🤦‍♀️😭

For me it was the Twitter & SurfShark VPN.

Not having problems ever since

I had an interesting problem yesterday with battery draining on my M1 MacBook Air very quickly. It was the optimized battery charging setting acting very strange. It was draining the battery at a rapid rate despite the fact that I was already running on battery power. It only drained to 80% or so but still it seems like a waste to just drain away battery power for no good reason while already on battery.

Part of the problem is that I've changed my usage pattern in the last few weeks. I went from almost always on the charger with my MBA in clamshell to working onsite on battery for 8-9 hours a day on battery the whole time. But it still feels like a bug for the battery to drain rapidly to 80% while already running on battery.

This happened to me when 100-90% would go on in a matter of 30 mins. Just doing normal stuff like writing in Visual Code or browsing the web

I've been monitoring the battery values pretty closely for the last few weeks since I'm still trying to understand the optimized battery charging algorithm. Because of this close monitoring I've seen the rapid battery drain several times while on the charger so I recognized what was happening even though I was on battery power. The battery drains at over 12 Watts until it reaches about 80% (ioreg values not macOS reported battery levels.)

What I'm beginning to understand is that OBC has a couple of modes. For my previous use it was about maintaining the battery level at 80% because my MacBook was rarely off the charger but now it is once back on battery, charge to 100% then drain back to 80% after a few hours if the algorithm thinks that the MacBook is going to remain on the charger. So far, the OBC algorithm is still confused by weekdays vs weekends.
