Hi, I've bought my new MacBook Air M1 at the end of November. I've now taken a look at battery health, and it says it is at a maximum capacity of 84%. Since Feb. 2021 I've been using AlDente at 79% because I mostly use the mac attached to a monitor and powered.

How can this happen, and is it normal?

I would say that isn't normal. Do you know how many charge cycles it has? You can find this using the System Information application. Normally accessed by using About This Mac and then the System Report button. Go to the power item in the left side list.

My battery has a cycle count of 40 and I'm still showing 100% on Apple's Battery Health system setting. Using the actual battery full charge ÷ design capacity, I'm down to 96.8%. I've had this M1 MacBook Air since launch day in November 2020.

Yeah, I've just looked at it and I'm at 45 cycles.

Battery condition information:
Number of cycles: 45
Condition: Good
Maximum capacity: 84

I would take that to the closest Apple Store to have it looked at. 84% after nine months and 45 cycles does not seem normal at all.

The battery is supposed to last about 1000 cycles. The capacity is way too low for only 45 cycles. Have Apple take a look and they will probably replace the battery as defective.

Bought M1 Air on beginning of January. Used it quite extensively for my work purposes up until mid May. So 4 months of active use, then only sudden browsing and that is it.
Currently have 67 cycles. Mac OS battery health is 94%, coconut battery is at 89%. Overall i am not really happy with these results - my old MBP 13 retina 2012, have shown me 90% after only 500+ cycles.

Maybe calibration? AlDente is bad for maintaining calibration. Try to fully discharge and then fully charge.

Final Update:
I have brought the Mac into an Apple Store. They ran their diagnose and showed some kind of graph like this:

As seen the battery is on a quick drop.

They say, they would usually only replace the battery, when it is in the red area. But as the genius himself saw the quite quick drop he said they could send it in for a free replacement.

The Mac arrived yesterday back home and it has been all good.

Glad you got it taken care of. It's unfortunate that you had battery issues with your M1 MBA. That's the only Apple device that I have right now that has had excellent battery performance. My iPhone 12 Pro and Apple Watch Series 5 both die very quickly and the battery health has plummeted on both in a year or less. My iPad Pro is decent, but compared to the M1 MBA, it's nothing special.
