This persisting issue ever since macOS moved from Monterrey is still not fixed. As soon as Monterrey was dropped the optimized battery charging feature stopped working. There have been many posts such as these in the community forums looking for workarounds, some claim to have found solutions, others like me are still waiting. I have tried all manual troubleshooting with no success.

Give it 3 weeks and report back your findings.
The current stable release of Sequoia including bug fixes, security updates is macOS 15.0.1

Sorry but what seems to be the issue ?
The image provided is showing the Battery is Charged to 97% of capacity.
The computer does not appear to be connected to the charger either

Since then the charge goes up to 100% for a random amount of time (sometimes it's a couple of hours) and then goes down to 80% arbitrarily, consuming charge cycles for no reason.
The "learning algorithm" is horrible.

Sounds like it is working as expect. The battery needs exercising...
I am fascinated by how many people fixate over their battery charging.
Let the software work for you. Forget about it.
The rule of thumb—
if you are near the mains leave it plugged in, if you need the portability then run on the battery only—this is how you help optimize your battery charging and extend the working life of your battery by reducing the cycle count.
you have an expected 1000 cycle count,
when your battery health is ≤ 80% maximum capacity is when Apple suggests the battery is eligible for replacement. At that point replace the battery:

My battery is such a slacker with nothing to do. So much so that one day it said: you know what, I need to do two full weeks of exercise, arbitrarily dropping to 80% and charging back to 100% for no reason. Might as well burn through charge cycles for no apparent reason. That’ll be great for my health. :)
Who knows how much longer it’ll keep up this overly optimistic drive to hit the gym every 2 hours.
Same problem.
I work on different things from 8am to 10pm.
For 3 weeks my macbook pro 14 m3 pro was at 100% charge always connected to the power cord and an external monitor until it "learned my routine". I would use it until 10pm, turn it off completely, unplug the charger until the next day. One day I forgot to unplug the charger after turning it off (apparently the optimized charging doesn't work if you turn off the macbook completely) and the next morning I noticed it was at 100% (led on the charging cable was green). That was enough for the charging function to stop working properly.
4 days later I went to an event where I could work during downtime so I used it for a couple of hours without charging and the battery woke up at 100% and I used it up to 90%. Then I found a place to charge the device and it decided to charge at 100%.
Since then the charge goes up to 100% for a random amount of time (sometimes it's a couple of hours) and then goes down to 80% arbitrarily, consuming charge cycles for no reason. The "learning algorithm" is horrible.

Do you think that amount of exercise is good enough for this week?
Or will it need more on some days?
Does Apple offer a virtual gym service for batteries, or is that also unavailable in LATAM like the easy battery replacement?
You’re right, I should stop worrying—the algorithm works perfectly, randomly draining and charging the battery. :)
this user just denies the problem and is harming people who legitimately want help and recognition of the problem facing their OS, constantly posting that there is no problem despite screenshots and evidence to the contrary, it is a net negative and probably trolling
The charger always keeps the macbook at 100% and never changes into optimized battery charging
To add
The more erratic the charging patterns the longer it will take to Learn
come back in Two and a half weeks or maybe Three weeks
Optimized Battery Charging does not work in Sequoia
