This is explained by the potential danger of overheating
The iPhone 15 finally gets a USB-C port, something many have been waiting for. But after the start of sales, it became clear that everything with this function is very ambiguous. So, as it turned out, not all cables from famous brands are compatible with the iPhone 15, and now official Apple stores in China have even begun to dissuade users from using cables for Android smartphones with the iPhone 15.
Apple stores warn against using 15 USB-C cables for Android smartphones with iPhones
The first such store was the Apple Store in Foshan (Guangdong Province), but now users report that they have begun to receive similar recommendations from other stores. Points of sale believe that using third-party cables may cause overheating. This is due to the peculiarities of the location of the contacts.
Such recommendations caused a flurry of criticism against official Apple stores. Firstly, many have already been able to verify that their new iPhone 15 is compatible with third-party cables. Secondly, there is an opinion that in this way Apple persuades users to purchase original cables, which are much more expensive than third-party ones.
