Charging a lithium battery to 80% only?

My older intel based macbook pro has started to tell me i use it mostly plugged in and won't charge higher than 80% on its own. There's also a 'charge now' button.

I'm not even on a recent Mac OS, it's still on Monterey. No extra apps to handle battery.

Of course, it doesn't look like a hard limit, but something triggered by usage patterns.

My problem with the built-in charging limiter is that if you are not extremely consistent in your usage patterns (I am not), it basically never kicks in. I much prefer a manual solution.

This is my problem as well. It‘s nice _when_ it kicks in, but too inconsistent.

Why oh why can‘t Apple just add a hard 80% limit switch somewhere in the battery settings. What happened to thinking of nature, guys?

Hmm yeah, I changed my pattern and used the laptop on battery for like a week and the charging only to 80% message is gone.
