> I seldom, if ever, carry my iPhone outside my house.
This is such an extreme outlier behavior, nobody is designing products around it. Pretty much everyone who owns a smartphone carries it around everywhere, because why not.
Not OP but I know quite a few people who really do not like to carry their phone around.
I couldn't understand this for the longest time until I asked my sister, who kept handing her phone to me to hold on to while on a family trip, about this one day. Apparently, a lot of women's clothing doesn't have "usable" pockets (they're tiny or fake...)! And with the size of modern phones, it's actually often quite a nuisance to carry around a phone.
While this may not be OP's situation, I would guess this might be one reason for the proliferation of cellular-enabled smart watches...
