Please share the battery capacity of your Macbook Pro 2021 M1 Pro/Max 14/16!

[Appletoni]

-6% = 94% after 5 months.
Most of the time I used only the CPU.

And I'm sure I will get -12% up to -24% in the next 5 months too.
=between 82% and 70% after 10 months.

=When the battery is full and the MacBook Pro 16-inch M1 MAX is plugged in, then it should use the power from the cable like a desktop computer but not the power from the battery.

 

[pshufd]

Is this true in Ventura? I can’t find this just an optimize button and my mbp charges all the way to 100%

It switches to the 80% mode automatically.

You can tell it to charge to 100% if it is at the 80% mode.

 

[transphasic]

Anyone know how long the charger must be attached before the OS reduces the battery power level down to 80%? I unplugged it for about 5 minutes earlier today, and after re-connecting it to my ASD, the laptop has been charged to a full 100%.

Is there a way to force the OS to max the charge at 80%? (I'm on Monterey 12.6.1).

 

[smoking monkey]

M1 16" Max. I'm down to 94%. But I use my computer on battery a lot. Not because I want to, but because it often gets used in situations without being able to plug it in as I'm often on the go or in multiple locations in a single day. Still, 94% after 1 year is a little much I feel. At this rate I'll be looking at a new battery after 3.5 years.

Mine never does that and the optimised battery charging never worked since I got the laptop back in January!?

Apple say 94% but coconutBattery say 89%

I think it kicks in / is supposed to kick in when the laptop is plugged in for a certain amount of hours, but for some reason, today it hasn't.

The ONLY change I've made to my computer in the last few days is downloading coconut battery app, and I hope that that is not the issue.

I have coconut for years and I recently noticeds that it is showing my battery health 89% and Apple is showing 94%!?
I am not the only one who has this.

I am running into the same thing apple shows 97% and coconut 94%. someone said on here that apples is an average. I was thinking about just getting another MacBook Pro but if all of them degrade this fast I will be right back at 94% next year.

Coconut was at 97% a week ago, no idea how did I drop to 89%!?

 

[transphasic]

I am not sure coconut is a useful app right now; it seemed to be forcing the battery to remain charged at 100% until I deleted the app. Now the battery charge is dropping down towards 80%. I would suggest deleting it and its folder in application support. 3rd party apps make me a bit nervous, and the weird battery actions after I installed it were a good example of the quirks they sometimes can introduce.

anyone else having this happen?

why doesn't apple adopt these settings? can AlDenete recalibrate/restore lost health?

 

[BigMcGuire]

why doesn't apple adopt these settings? can AlDenete recalibrate/restore lost health?

It would add complexity to iOS that Apple doesn't want. I can imagine the uptick in support calls: "Why isn't my phone charging past 70%?! I hate iOS, Apple is horrible!"

I do hope Apple adds these settings in the future, but that's my take on it.

AlDente just prevents charging. It can try to recalibrate the % reader and in that spect you might gain a few % but in the real sense, it won't restore lost health. Batteries can do with occasional full'er cycles to help calibrate the % reader, but that's it.

so if AlDenete stops charging how does that impact cycle count? does that equal more cycles?

coconutBattery cannot force the laptop to remain charged at 100%. Optimized battery with Mac OS is entirely a separate feature depending on your charging habits as far as I know. <shrug>

While I agree with you that 3rd party apps make me a bit nervous, coconutBattery and AlDente have been long time apps that have been tested and tried. coconutBattery is great for recording Apple's own battery stats. To get then you can run in Terminal (please note that I got this from another very helpful Macrumors member (not my own)):

ioreg -l -w0 | grep AppleRawMaxCapacity

ioreg -l -w0 | grep DesignCapacity | tail -1

AlDente just allows you to turn off battery charging at a % and run off of the mains thus helping battery longevity. Apple's Optimized Battery feature will do 80% after several weeks of consistent charging but users find that it is not consistent and it can turn off whenever (I've seen this on my wife's laptop).

 

[BigMcGuire]

so if AlDenete stops charging how does that impact cycle count? does that equal more cycles?

Right so if AlDente stops the charging, the laptop will run off of wall power entirely thus causing cycles to not be used. I've done this in such a way that an entire month plugged in - I used no additional cycles on previous laptops.

But batteries like to be used and so sailing is recommended - cycles are not as harmful as keeping the laptop at a high state of charge for long periods of time (hence why AlDente is so helpful).

 

[BigMcGuire]

Coconut was at 97% a week ago, no idea how did I drop to 89%!?

I don't know what is going on with health readings but in all the years I've used MacBooks I've never seen the health % be so variable as I have this year and last year. They used to be REALLY static... and now it's not uncommon for them to jump all over the place.

I have a 13' MBP 2021 and a 16' MBP. It's not uncommon to see battery health swing 3-5% in coconutBattery these days (pulling from Apple's own stats).


For you specifically - I would make sure you're taking a reading at the same state of charge to get consistency. I think Apple drops the voltage for those of us who are plugged in a long time and this can reflect in health %. At 100% charge, health is usually 100% for me when I do that. When at 60% charge, my health can be 95% or so. <shrug>.

If I was in your situation and had a drop to 89% I'd do a drain to 40% state of charge, then charge to 100% and then monitor the health % over the course of the next week. I'd take long term monitoring over a quick % diff anyway - this is where coconutBattery shines.

My 2021 MBP 13' that started out at 100.8% capacity from factory purchased 9/12/21:

What is the recommendation? Get a new machine?

 

[BigMcGuire]

What is the recommendation? Get a new machine?

If a laptop battery truly goes from 97% to 89% and this is seen over time, then that usually indicates a failing battery and it should continue to drop. A 16' MBP could still be under warranty so the user should keep an eye on the health and once it drops below 80%, demand a replacement from Apple. Hopefully they had AppleCare+.

Apple warranties batteries at 80% capacity over several years at 1000 cycles. So at 89% the battery is still within tolerance levels. It would have to go <80% capacity for Apple to give it a replacement.

My hope is that it's just a fluke reading and that after a cycle the reading goes back to normal. That's why it is important to read battery health over time - not just at one instance.

 

[transphasic]

Well, the OS finally reduced my battery level down to the 80% it is supposed to be at. Where there is smoke, there is fire, and the only change I made was deleting the coconut battery app, so even though it is believed to be just reading the battery - it must be doing something more.

So...could this be what is ailing our 14/16" MBP batteries?

Apple's Battery Health Management Feature Cannot Be Disabled on Apple Silicon Macs

Apple's battery health management feature cannot be disabled on Apple Silicon Macs, as there is no toggle switch for this in System Preferences...

www.macrumors.com

MacOS allows Intel-based MacBook users to select a "Manage Battery Longevity" checkbox option in the "Battery Health" pop-up window. There is no such option to disable this in MacOS for M1 MacBooks. So has MacOS reduced my capacity based on my usage? All I do is leave it plugged in all the time and every so often unplug to use on the couch.

How very interesting. Might explain the capacity drops? I use my MBP very similarly to you. Nice find.

While I do believe Coconut battery gives a closer approximation. my 16" is less than a year old and I am at 89%. Apple will do nothing about this because under my Apple battery health I got 94%. I agree with Mike Boreham reply here
