MacBook Air M1 battery life

No, it's not normal. I think iStatmenu has still some serious glitches when it comes to M1 sensors
The hours of battery remain are increasing slowly but I can see that is the same with the activity monitor:
more or less the same here. The main iStamenu glitch is related to the battery health status that shows 2% (maintenance needed) on my MBA M1 with 2 battery cycles ?

However I've just noticed that I had the brightness to 100% so now I see a more decent battery remaining. It is so beautiful the display to full brightness
(sorry for the English)Mine says 99.6% and its about 3 weeks old with 5 cycles according to CoconutBattery, but macOS says its 100%?
LI-Battery degradation is always high in the beginning. But it should flatten later.
Staying at high voltage, accelerates the degradation
The best option is: Do not charge through 100%. This is what Apple does.

Similar situation here with my M1 Pro - 97% after 4 cycles, very disappointed.
Coconut reads the 'raw' battery info, you can get the same stats if you use the following in console and look at "AppleRawMaxCapacity".
ioreg -l -w0 |grep Capacity
Reckon this info can be used to raise the issue with apple as it's pulled from their console. Again, they are hiding battery data as the 100% we can see in system info is bogus!
I had two units, the first one had solid battery but a faulty ambient light sensor and I had it replaced. Now the second one has a Mickey Mouse battery

Apple is doing this for years. Many years. On my old 2010 MacBook Pro this already happened. Coconut and other readings said my battery was close to 80% health with a few months, the genius ran the test, and magically the battery was healthy on the 89-92% (I don’t remember the number exactly) so they didn’t aknowledge the battery was faulty.
This should be investigated by a consumers organization. You could try ti file a lawsuit in the US, as it seems its a good country to open a lawsuit and fight for a cause
I just made this same post in another thread and I think it applies here as well.Similar situation here with my M1 Pro - 97% after 4 cycles, very disappointed.

There is nothing wrong with your new M1. You will drive yourself crazy constantly checking Coconut Battery.
Your battery is an ever changing chemical process. Battery health is an estimate and should not be treated as a static result.
The OS does a very good job analyzing your battery and making sure it isn't overcharged and will alert you if there is a potential problem.
Run the Apple hardware diagnostics test. I bet it will come back good with no problems found (re: battery).

I agree with you in regards to the constant checking of the battery and that fluctuations are normal, but it's just strange when there is such a big degradation over such a short period of time.
Apple batteries are just getting worse unfortunately. One of my old laptops, 11'' 2014 MacBook Air has 540 cycles and a battery health of 86%. My 2016 Pro is at 87% with only 190 cycles.
Also, funny bit, I can't run the diagnostics test as it keeps freezing
) (not the 'ram test' type of freezing, it just doesn't work).

Cycles aren't the end all be all for battery health. Your battery is still going to degrade if it's plugged in more often, which leads to less cycles. You'll eventually lose battery capacity, and also get swelling.
That is my experience too that their own diagnostics claim battery is around 10% better than readings you get with apps. I had that with my iPad loosing FCC fast and that also show in run times getting down too fast but their diagnostics said nothing wrong and reading was about 10% higher than what I saw with apps.
Does the M1 battery live up to the hype as apple claims? I probably have to charge my macbook air at least 1 time a day before the battery totally drains itself and 5 times a day to have it maintain its percentage in the range of 50~90.
So I think the battery performance is overhyped. Then I checked the system report, in the battery panel, the battery model information reads "Device Name: bq20z451".
Then I searched online such name, I found that in several posts from 2010 some people said their mac had the battery with exactly the same device name.
After that I have been pretty worried if my m1 macbook had been tampered with by someone such as the product line workers who assembled the older generation battery into the mac in the manufacturing factory here in my country.
I was wondering what is the device name on your mac? Can you check that when available? Thanks!

Same here on my MacBook Pro M1. (the 3rd one replaced by Apple)
What do you use it for?
Also, do you have a reading from Coconut Battery?
No. At least not in my experience with actually using the machine with decently high brightness. Battery is 50W and basically display on while machine is idling (just desktop) easily uses 2-3W per hour, and when you do something it easily uses more.
My experience is that it is like 30% better run time than MBP 13" 2019 was (that gave me like around 7 hours (give or take 1 hour) when actually using it).
I think most peoples count the hours between charging, even when the machine is sleeping included. Or they just read the reported hours in battery menu, which I have no trust after it claimed I used the machine for like 5-6 hours with about 10% or so battery use.
It is normal. Check battery serial with Coconutbattery or similar and you'll see if it is correct or not.
I don't think so, that is very unlikely.
I have had my M1 MBA since 4pm on 12/24 and I have had 5 cycles. Better Battery 2 app shows battery condition to be 100%. CoConut Battery also show design capacity to be 100%.I agree with you in regards to the constant checking of the battery and that fluctuations are normal, but it's just strange when there is such a big degradation over such a short period of time.

Counting cycles should not be the focus, in my opinion.
Meaning use batt until 10% before recharge to 100% and repeat the cycle again? How do u define regular basis?
I have my Air M1 for almost a month now, I keep it plugged in at all times at home
I have it stuck to an usb3 dock that runs a 4k 60hz tv as a monitor and also goes to the audio system, apple bluetooth keyboard and mouse, never actually open the lid, interestingly the last 3 days its been sitting on 88-87% charge and says "its not charging" I assume is an automatic state designed for long periods of desktop use, since I have been using it but haven't physically touched it in 3 days.
Its been on 5 cycles for about a week now. One day I played stellaris unplugged for a few hours (3 hours tops) to see how long it would last (from 100%) but I got distracted and it went down to 0% and it took a whole cycle away and 1% battery health with it.
Id like to know if other intense desktop users have this same experience, I was tempted to unplug-plug-it-back to see what happens but I am more interested on seeing how far it goes like this, and how long it takes to do one cycle if plugged in all week consistently.
PD this mb air totally smokes my 15inch i7 2016 460pro in every way
