Battery service recommendation on New Air M1

jephdub · Dec 28, 2020

Is anyone else getting battery service recommendation. Cycle count 5 with 100% capacity showing service recommendation.

Is this a bug?

Bring it in for a "Genius" Bar appointment. Strange that it also shows Maximum Capacity at 100%.. Could just be a defective battery, and if that's the case, they will replace it. (Batter is adhered to the top case w/ keyboard)

OP, follow the instructions with this support document. If you get the same battery service code two times, you need to contact Apple.

Where is that report found in Big Sur? I can't find it.

Not running Big Slur over here, but the OP's screenshot was from the System Information app in the Power (About This Mac screen)

Thanks. It has been a while since I had a MacBook, and I am still trying to get reacquainted with where everything is on the M1. I haven't had to check battery status on a MB in a few years.

Sorry to hear you’re having this with an Apple Silicon MacBook as well. I posted this thread today documenting similar issues:

Big Sur = Dead MacBook Pro Battery

Hey everyone—it seems that last week after upgrading my 2018 13" Touchbar MacBook Pro my battery failed. I wasn't even able to start the computer for 2 days because I would only get the red battery drained icon despite it being plugged in. It was so soon after the OS update that I was...

forums.macrumors.com

It seems the update introduced some sort of firmware update that is bricking the battery (or maybe just breaking the software on the battery and throwing an error).

Are you planning to bring it in for servicing? Or hold off and monitor?

I think i'm going to hold off & monitor,

already run diagnostic then the result is no issues found.

Ran the diagnostics and no issues found. So does this mean it’s likely a software related issue?

I would think so.

I get the same even after Big Sur 11.2 idk WTF Apple is doing I have MacBookPro 13" M1

Software bug? A couple of days after receiving my M1 Air I was shocked to see that screen showing Cycle Count 34. I was too distressed to think of a screen grab! But next day it was back to normal and showing Cycle Count 3, and is currently on 6.

Hello folks, same issue for me. Let me share what I discovered.

System Information -> Power (Maximum Capacity: 100%)
My old MacBook Pro 2020 (Full Charge Capcity (mAh) : 4665)
For M1 there is no Full Charge Capcity (mAh) instead that Maximum Capacity in %
Going forward and run in terminal: ioreg -w 0 -f -r -c AppleSmartBattery
And as you see there are no issues as well
Run Apple diagnostic: no issues
By the way forgot to mention, I did not start with clean instal when had bought MacBook Air m1. I run through 'Assistance Migration' and restored from backup of my MacBook Pro 2020 on Intel

Conclusions: Looks like Alert triggered/triggering by the fact that it is looking in the field Maximum Capacity which is in % but parsing it as field in mAh. Hope Apple will fix that in 11.3 (in 11.2.1 not fixed)

For what it is worth, my wife's MacBook Air (Intel, from a few years ago) is also having major batter issues since upgrading to Big Sur. It used to last 4+ hours, but now shuts down in under and hour (sometimes as little as 15 minutes). (Note: I'd need to see it happening, but from what my wife says, it seems like a hard-shutdown... apps have to be re-opened and recovered, so it isn't just going to sleep.)

I think, as the last post indicates, Apple has something really messed up on the way they are reading the battery state.
