I forget when, but in last ~3-5yrs, I've noticed iOS seems to handle this. If you leave a device plugged in for a long period you eventually getting a notification saying it's not gonna charge as much, and it caps the max battery to 80%.
Just wondering if your story is before or after that feature.
