Yes, there is no such difference between the two sides. Both sides have the same design. Apple designed the front and back just for simplicity.
When the charging head of a mobile phone is used to charge a pad, a charger without a pad will charge faster, but there is no difference between the front and back of a data cable. If there is a real difference, the product will not retain the one that charges slowly. That side.
Telecom Mobile Network consulted Apple supply chain wire engineers and learned that the iPhone 6 data cable has an adaptive IC added to match the USB double-sided design (the MicroUSB data cable used on Android does not have an IC and cannot be reversed at will) Insert). In addition to the most intuitive advantage of being usable both front and back, it can also increase the metal contact area of ??the USB middle layer. In this way, it will not only be compatible with the current highest-end 12W adapter for iPad, but also be expected to realize Apple’s unreleased 20V ultra-fast charging patented technology.
