I don't think I used the word "harm" in my post but okay, obviously the battery will still function normally just with shorter and shorter range. So in that sense it is harming range.
Going below 20% doesn't hurt Lithium Ion battery health. Going over 50-54% does, but not much unless you go over 80-90%.
One would tend to equate "hurt" and "harm"
Are you harming a battery by owning one? Of course not. Just owning a battery and letting it age will decrease the capacity.
There is a report on long term 100% charge storage, If I remember correctly, the degradation over a year was 7%.
BUT 3-4% of that was based on simple aging.
After about the first year, batteries will degrade to a certain level. Once they hit that level, they tend to stay close to that level for many years.
