Are you saying that a few events of prolonged 100% CPU caused permanent battery degradation? I don't think that is correct. FWIW I frequently run my MBAs at 100% analysing chess games with Stockfish, and still at 99% after 19 months.
Yes it was like 100% all cores overnight, extremely hot computer. Also at some point it like crashed the OS so it may have bypassed thermal throttling

Here is my 13" M1 MBP

For first 100 cycles it lost battery capacity very rapidly.

However once it reached 82-83% it stopped ageing.

It's been almost over 7 months and 120 cycles with the battery health percentage is still stuck between 82-83%
Mine is basically the same, I think there wqs possibly something wrong with battery management in early arm64 macOS versions that is now fixed

I think I was also having some early macOS issue with Thunderbolt monitors not letting the machine deep sleep ¯\_(ツ)_/¯

Either way I’m not sweating it. It still lasts me all day when traveling and like I said if it ever gets too bad I’ll just have it repaired or do it myself. I get enough value out of these machines to invest in their upkeep

It's 1 year old and you worry about 1%. Extrapolating 9 years, it will still have 90% of battery capacity left. Just use it however you want and don't worry about it.

I dont understand one thing, like i said in my previous post,
now as i have installed AlDente and charged the MBP to 80% and its stopped charging it, i have finished my work and unplugged it and kept it in my bag, after few hours i have some work again so should i connect the charger again to do work or should i use battery which is on 80% charge?

How are you using your laptop? I'm really curious

Very light usage (web browsing/video streaming/social). I have a desktop PC for intensive tasks.
And runs exclusively on battery (like an iPhone/iPad), only plugged in for charging while not being used.

Oh makes sense! I spend 90% of my time in Clamshell mode... I only take it off usually during the mornings in summer to work by the pool or during trips...

As I said, just use it as if you didnt have AlDente installed. I don't see that this is a question other people can answer for you.

Do you want the machine to be at 80% after your next work session or not? How long will your next session be? ie how low would you expect battery to be after next work session if you didn't plug it in? Would that be OK?

These are the everyday choices all laptop users make all the time, with or without AlDente, which just changes full charge from 100% to 80% (if that is what you have set).

I charge mine to 100%, take it off the charger and use it until the end of the day. I usually let it sit overnight and charge it in the morning back to 100% and repeat. I don't use Al Dente, Coconut battery or any other third party app. My battery health is still at 100% and I've had my M1 Pro MBP since launch.

What I've found is that simply using the device keeps it healthy. Whenever I've stopped using a battery powered device that's when the battery health drops rapidly.

This is how i was using MBP till that youtuber guided me wrongly, and health was 100%. I will start using like before only now.
Actually i had Macbook Gold which was launched in 2014-2015, and it died in 2 years, there was no power (not turning on) consulted apple support and they told me that they have to replace the logic board which will cost me 750 US$, then i visited local repair shop and they just recovered my 200GB data from It in 200US$. i dont want to experience that thing again. And Indian Apple Support is just of no use. they are big time moron. Thats why i was worried about battery health :(

Use as you please, but it’s best to keep between 40-80% ideally. Use battery optimiser yeah.
And do not listen to that guy, horrible advice. You shouldn’t keep a battery device plugged. That is what will ruin it. Only when you need it charged.

99% is perfectly fine. My 2015 air is around 80% and still holds well.

And you can shut down your Mac if you need to. Don’t “never” shut it down.
I’ve had my MacBooks sometimes reaching well over 100 days of uptime and only restarting due to updates or a small glitch etc. But you should do it every now and again
Brother, I was planning to buy a usb c 4k monitor for m1 mbp, and i remember that you and someone else told not to keep mbp charging all the time, but if i buy this monitor it will keep it charging all the time, then whats the solution for it?
is there any charging off kind of option in usb c monitor?
or should i drop the idea to buy the monitor

AlDente will do the same job whether you are charging from a monitor or a hub or a wall charger. Makes no difference. One of my M1 MBAs is charged via the 24" LG Ultrafine and one via an OWC powered hub.

Don’t worry about it just use Aldente, regardless eventually you going to need to switch out the battery after 3 years.

Newer machines and OS versions take care of it for you by rotating the charge between the cells and only charging to 80% by default. As long as you're current on those, just plug it in and use it.

The very worst thing you can do is to run it empty and charge it full every day. It's the last 20% on each end that wears the battery the most. Fast charging is also more damaging than slow charging (heat the the enemy there) (that's why Tesla recommends only using superchargers occasionally). Apple's done a really good job over the past few years of improving their battery life and health management system. Let it do it's job. If you want extra, you can try aldente (I have), but I switched back to apple's built in stuff because it understands and interacts with the underlying hardware and firmware in a way that third-party apps can't.

Now if you're on an older machine, it might make sense. But for modern ones (especially M1's), don't overthink it.

just use it unplugged every other day, or i think you could disable charging on the monitor? or an adaptor? not sure

AFAIK USB-C (and Thunderbolt) monitors connect to the computer with a single cable which carries the video signal and the charge. My LG Ultrafine does.

Then what is the best way to use it? Optimising Battery is always on.
And i never shut down MBP.
I have discussed with a youtuber Aaron, Attaching the screenshot
Please guide me what to do after 100% charge how to use it?
Use AlDente. It caps your battery at a certain level (I suggest 70-75%).

From my last post on 7th Feb till today here is the new update
Health Information:
Cycle Count: 50
Condition: Normal
Maximum Capacity: 93%

only 50 cycle and health is at 93%, i use only for email, web browsing or some movie, thats really disgusting, tried aldante when the health was 94% and after 1 week it dropped to 93% 😭 i am worried about the battery as there is very high charge to replace the battery

That battery is failing. Apple charge a discounted ‘battery repair’ rate of about £250 to replace the top case these days as long as there is no damage present or other issues. It’s a lot cheaper than what a top case replacement usually costs.

AppleCare also covers batteries for 2 years if they go below 80%.
