It depends on lots of factors; but the degradation can be a lot more than that if you really abuse your battery. And unfortunately most devices don't make it easy to avoid being hard on your battery - you just kind of need to know what not to do, and play a guessing game. Apple specifically isn't one to burden the user with unnecessary mental load - so battery-health management is unsurprisingly something I've never seen on any apple device (but it's pretty rare anyhow).
