Being constantly charging is actually bad for the battery life. Being around 100% stresses it… so that’s why some Apple devices now try to determine how much ch

  It does. But does it stress it more than charging to 100% then draining it to, say, 10%, then charging it again? Hence, racking up cycles at a faster rate? I know it's anecdotal, but I mostly keep my battery-powered electronics plugged-in when possible, and their batteries tend to degrade much less over the years compared to a friend's, who tends to unplug them and charge them when needed. And the electronics in question are fairly similar: iPhones and same-gen Macbooks. Same for my work laptop (hp) which, after 4 years, still has around 80% of its original battery life, when my colleagues', who use them much more often on battery, only last around 50% of their new condition, if they weren't changed because of swelling. The one kind of battery among mine that seem to have shorter lives are camera batteries. Which, of course, tend to get drained more since I don't have an outlet handy when out in the woods.

  1.5 years old 12 Pro, 83% battery health. But I mostly do iOS software engineering, so the device spends most of it’s time plugged in. In a few months, it won’t even need to try to stay under 80% anymore. It just will.
