I have never heard of this functionality. Is this some magic setting somewhere? When I plug in my MacBook it charges to 100% and stays there. This isn't a Tesla: this is a laptop. When the pandemic started and I stopped traveling the battery in my MacBook very rapidly nearly fully died.
Regardless, all of my MacBooks eventually have battery problems whether they were plugged in all the time or not: it is extremely common for MacBook batteries to eventually get so damaged they start to swell and either need to be replaced or crack the case (and that's ignoring the fire hazard).

- manchmalscott 4y agoI'm pretty sure that article is talking about the feature where, if MacOS realizes that you always plug in your laptop at night, and unplug it every day at 7 am, it will pause charging at 80% until like 5:30 or whatever time it needs to, such that it will reach 100% exactly at 7 am.
- ubercow13 4y agoRight, it tries to guess and it's not very good at it. But IME if you do pretty much always use it plugged in as was being discussed above, it will just stay at 80%.
