The iPhone 12 will come with new USB-C cables from the Apple company, but this does not necessarily mean that we will be able to enjoy a new experience using phones, although we will have a new black cable available from now on.
The new USB-C cables that Apple brings to users of iPhone 12 phones will be made of textile material, and will be "embroidered", so there is a possibility that they will be somewhat more resistant than the current ones.
Of course, Apple will sell these new cables at higher prices than what we know now for current cables, but that shouldn't be a surprise to anyone, just seen as the new normal from Apple.
