My MBP M1, OS 12.3.1 has the feature of Optimized Battery Charging since I acquired it in Dec. 2020.
It worked very well charging the battery to max 80%, as required.
Since upgrading to OS 12.3.1 abt two weeks ago, it is charging the battery to full 100%, notwithstanding the fact that the relevant preference is ticked for Optimized Charging, as in attached pic.
Is there a cure for that, please?

I savvy nothing of batteries and wonder if it is possible that 100% is optimal.
Should I disconnect from adaptor, use to, say, 25%, then replug and look at the results?
Apple does not publish its "algorithm" for the optimized battery charging. But we know it is based on what is known about the types of batteries used in the laptops. For example, leaving a battery charged to 100% forever does shorten the life of the battery. Additionally, leaving it on 80% (as you observed) helps extend the life of the battery. But it also known that the battery should be "exercised" now and then, e.g. allow some discharge then recharge to 100%, then discharge etc. The Apple algorithm factors this information in to what it observes about your use and whether you leave it connected to the charger all the time. It may charge at 100% for a while to periodically exercise the battery. Staying there for a few weeks is not unusual, and also when it does eventually allow the charge to drop, on my laptops sometimes it does not end up at 80%, for instance right now one is on 76% and "on hold." What causes it to go to 100%? Several things -- sometimes rebooting the Mac resets the timer and may lead to it charging to 100%, where it may stay for a while. Or it may do that based on not wanting it to stay at 80% (or 76%) too long.
I think you are best off just putting the setting on what you want (optimized battery charging) and then leaving it alone. Keep in mind that the Mac collects information about battery use over some ~ weeks before it decides to make a change to the charging level when in "optimized" mode.
Agree with previous posting.
If the User wants to force battery to 100 % do as previously suggest.
Otherwise - forcing it to change to 100% every time may shorten to life of the battery which is exactly the opposite of Optimize Battery

This is all that Apple publishes:
If battery charging is paused or on hold on your Mac - Apple Support
About Optimized Battery Charging on your iPhone - Apple Support (one can assume this is true for macOS devices too).
@avra, Wondering if there's been any change in the charging behavior, now that it's been a few weeks?
I am experiencing something similar. My new MBP that I've had for about a month was consistently charging to 80% (as expected/preferred) with battery optimization enabled, and plugged in most of the time. A few days ago, I unplugged and ran the battery down quite a bit (perhaps ~25% +/-), and when I plugged it back in, it charged to 100%, where it's remained for the last few days. I'm hoping it will go back down soon.
Just as there is a way to over-ride optimized battery charging, I wish there was a way to force/manually control optimized battery charging.
There is no change at my end. When plugged to the adaptor, it is charging to 100%. Once a week I unplug it, let it go down to 20-25% and replug again. The 80% situation is dead and forgotten. I gave up on this one. Life is too short to worry abt it.
My M1 MBA Monterey 12.3.1 performs the Optimized Battery as expected.
Had this machine since March 2021
Thank you.
What do you mean by " performs the Optimized Battery as expected"?
Tops how many %?
Mine was max 80% from Dec 2020 until two weeks ago.
There was no change in my working routine.
Pls see attachments of my situation.
Where should I change?
Tks
Got it!
Thank you so much.
Enjoy Easter!

Only if you want to further delay the process.
Thank you all for your time and patience.
Thank you. I tried that some weeks ago. Did not work out for me, Un fact I gage up on that matter. Life is too short.
.
The end of Optimized Battery Charging?
