The standard iPhone lens (26mm) has always been pretty much normal for phone camera lenses. When Apple introduced the second lens (51mm), they called it "telephoto," even though that focal length is pretty much dead-on the traditional definition for a "standard" lens. No traditional photographer would call a 51mm lens a telephoto lens.
So, for people who grew up with phones as their primary cameras, the new 13mm lens really is the first thing that they'd call a "wide angle" lens.
