I mean, I cannot fully agree with you here, to be honest. Yes, partially. At one point, you say that, in a way, it also looks like something done for the sake of looking cool or stylish. Actually, you are right about that. I also have an iPhone, and I am not someone who uses wireless charging as if I am dependent on it. But that is not really the point.
The issue I am criticizing is this: they have brought us the wireless charging feature, and that is genuinely nice. If they had not brought it, it would have been somewhat more disappointing for users. At least they are not just trying to impress us superficially like some other companies. However, the features they brought with it are very limited.
The fact that it is so limited makes me think: you have a “The Other Half” feature on your phone, but adding wireless charging to it will not make a huge, remarkable difference. Maybe if it had offered good wattage support, then its addition could have been seen as somewhat more acceptable.
