This option is not new and it never really worked for me. Sometimes it would work fine for a while, then again it decides to keep the MacBook at full charge for weeks. I never really understood what Apple had in mind with this feature. Just give us a proper charge limiting option. With this tool you get exactly this, though limited to choosing 80% or off (charge to full) only. I would prefer a full charge limiter as I have in my Tesla, but for some reason that's beyond Apple.
