Lithium chemistry is more sensitive at the extremes of charge. As I understand it, the best battery life is achieved by maintaining the battery "in the middle" e.g. between 40% and 80% of capacity. This is why when you get a new cell phone, it's roughly half-charged.
In fact if you discharge the battery too much, it becomes impossible to recharge (the battery management electronics should prevent this). The worst thing for maintaining range over time is if you regularly discharge to near the minimum and then fully charge to 100%. So there will be some variation in the range remaining on used EVs of the same age and make, depending on how many "full charge cycles" the batteries have endured, among other factors.
