There are some new choices for Macs with Apple Silicon. Apple refers to their system for battery charging as “Optimized Battery Charging”; the OP’s query appears to be asking about “Restricted Battery Charging”. I really feel that lots of the points reported with Apple’s “Optimized Battery Charging” should do with how Apple has optimized it.
Apple’s software program is usually all proprietary and closed-source, so there is not any technique to know for positive what is going on on, however we do know that Apple depends on periodic “battery calibration” for reporting the state of cost. We additionally know that battery calibration requires occasional charging the battery to 100%.
Therein lies the issue:
Reaching the battery longevity advantages of sustaining an 80% cost stage
VS.
When & how typically to re-calibrate the battery by charging to 100% to take care of correct reporting?
How properly Apple has balanced these competing targets could rely quite a bit on the person person’s utilization profile. Which can clarify the variety of questions/complaints.
Additionally: On condition that Apple’s “calibration” retains the battery between 80% cost and 100% cost, one may marvel how efficient a calibration could be if it is saved in such a slim vary. There is a good article on the Battery College explaining how calibration works, and why it is worthwhile. However this isn’t how Apple does it… suffice it to say that apparently Apple has not learn (or would not imagine) this text.
In case your expertise with Apple’s “Optimized Battery Charging” leaves you feeling lower than enthusiastic, maybe you need to examine one of many apps that implements “Restricted Battery Charging”. This is a brief record of apps that implement “Restricted Battery Charging” for Macs with Apple Silicon:

On the whole, these “Restricted Battery Charging” apps focus nearly completely on battery longevity, and depart the periodic calibration operate to the person. This could quantity to easily disabling the cost limiting operate, and permitting the charger to cost to 100%.
