This is where I'm at with it too. Appears to me that MacOS is handling it, so I'm going to choose not to worry about it. I use the laptop when I want to, plug it in when I don't. For the most part, it seems to charge to 80% and hold. But not always. Other things to worry about!i wouldn't worry about it, macos manages the battery charge and discharge pretty well, i used to run al dente which you can cap the charge at 50% if thats something you are interested in.
