I use the paid version of an app called Al Dente [1] to set the battery charging level to a specific limit. The app has a free mode. It has more features than what I stated, and works on Intel Macs and Apple Silicon Macs (limited only by what the underlying hardware allows).

I don't know if they changed this, but I think AlDente follows a polling approach where it periodically checks the charge level and enable/disable the charging accordingly. Such solution is more hacky and it also could cause some sleep-related issues.

The SMC key discovered my marcan is nicer because it enables the same functionality without having to poll anything, as it's built into macOS.

Furthermore, I don't care about all the extra stuff they have put into AlDente, I just want to keep my battery at 80%.

I had such a switch in my old Samsung laptop. Works much better than software-based solutions, which are often simply unreliable.

Subscription pricing eh?

There’s a free version that allows you to limit the charging to a specific level. I found this app useful over the years and I bought the lifetime license when it was on a sale. Otherwise I wouldn’t have paid for it since I don’t like the idea of subscriptions either.
