Maybe the attitude to run the battery low before charging it comes from NiCd batteries which have the so called memory effect [1].

Could education be the answer? I've never bought an iPhone, do they include a few paragraphs about proper battery care?

Apple has had a web page about batteries and good maintenance practices [1] for several years now. But most people wouldn't know about it or read it unless they searched for it.
