Optimized battery charging issue solved ( MBP 2020, macOS Ventura )

I've fixed the issue of optimized battery charging feature and now it is working.

It looks like so called learning algorithm can not track the charging status if you connect the charger before you start the computer.

Here are the steps you need to do to fix the issue.

Turn off the optimized battery charging feature (Uncheck the "optimised battery charging" option in the battery settings ) ( this is necessary to make a fresh start )
Unplug the power cable
Restart the computer
After the restart turn on optimized battery charging
And then plug your charging cable

These steps helped me to resolve the issue instantly.

Thank you Steve,

Currently I've already have some solutions in my hand like other thirty party developers but they mostly works with communicating with the SMC at low level. But I do not prefer that kind of solution. I need an elegant solution.

As my research continuous ( without any documentation and most of the source codes are closed ) I think I've found the service which is at the top of command chain ( PowerUIAgent ). It is responsible for giving charge decisions based on machine learning models. And I succeed in communicating with that service.

In this way I believe I can override some settings or tweak some parameters of the decision making logic.

I'll keep this forum posted once I found alternatives.

Extra note : Yesterday when I'm evaluating the alternatives, I found a power assertion ( like the assertion that prevents sleep ) but it doesn't work. ( like I think it should ) It's name is "kSBUCChargeInhibit"
