14" MBP battery already dropped to 99%

[OhMyMy]

It's only got 21 cycles on it and 2 of them were already there when I got it. Coconut battery fluctuates between 95 and 97 but the system report now shows 99%. How could a brand new laptop battery drop that quickly with only 21 cycles?

Anyone else seeing this?

That does seem surprising but I don't think that % is entirely accurate. I personally would not worry about unless you start seeing obvious reduction in battery life.

I use coconut app and after a couple days mine dropped to 98% but when I looked at the MacBook pros 16” battery health it showed 100% still. So I don’t believe these apps that people use entirely.

I remember when I bought a brand new MacBook Air and downloaded some battery app that I've used previously on my old MacBook.
It showed my battery life as 76% but in preferences - Battery Health it was 100%. So yeah, no reason to believe those.

Maybe I wasn't clear in my post. The 99% that got me a bit annoyed is in the macOS' System Report itself and not a third party app.

I didn't say it is.
You misunderstood me

OS' battery reading typically stays at 100% for at least a couple months usually which is what is frustrating in this case. I wouldn't be too worried if it stays at 99% for awhile though.

You should be aware that the Apple battery health is not always accurate. That is because the 100% is relative to when the battery was new. If the battery at manufacture had a lower capacity than the design value then the battery could be showing 100% and the actual battery capacity could be lower. Coconut battery gives the true battery percentage relative to the design capacity. It actually uses information in Apples own software, accessible in terminal on your own MacBook (without using coconut battery) by an ioreg command (just Google it).
My MacBook arrived with 2 charge cycles, now has 4, says 100% charged but the terminal command shows my full capacity is 97.7% of its design value.
I.e. For me, terminal gives
‘DesignCapacity’=8694
‘AppleRawMaxCapacity’=8492
So, 97.7%. Looks like the battery has been sitting around for a few months so I’m hoping it will up a bit with a few more charges, once the electrons get moving a bit as it were, break through a few bonds being a bit clingy and stopping them from being as free as they ought to be.

That's nothing. 100 cycles and only 87% on a MBP 13" 2020.

It sounds like you’ve had that plugged in most of the time and that’s detrimental to battery life. Especially when it’s sitting at 100% battery most of that time.

That's the point... (lot of home office).
I thought, that Apple battery optimization will help - but it does not.

Kinda stupid.

As long as it's 80% not stuck at 100% it should be fine. Even better is 50% . But again. Apple's own implementation is kinda meh sometimes. Like it doesn't recognize my usage that well.

Thx for the feedback. What about AlDente? Maybe it's better to use this, because my Macbook will be connected to power quite often (because of work).

Yes. I am using it . Just set the max to 50% . If you're plugged in all the time. Calibrate it every 2 months or so. (calibration is for the fuel gauge so when you use it without power. The percentage is accurate)

Thx for your help. Set it to 55% and if I need a longer I will use "Top up" at the moment. (Just testing the free version.)

Do you also use 'sailing'? And why calibration instead of simply use "Top up"?

Because sometimes going to 100% wouldn't really calibrate it. If you see the AlDente's calibration mode. It's even going down to 15% .

But yeh. Top up is fine. I use it at 50% and it's fine. If I know I'm gonna go somewhere. Just use the top up button. Done lol.

Its pretty nice actually
