A lightning cable that is reversible is used by Apple to charge and sync the iPhone. Lightning is extremely superior to the Micro USB cable used by Android phones to charge.
Compared to a Lightning cable, Micro USB feels archaic.
There is no wrong way to plug a Lightning cable in, because due to a lack of a top or bottom. Android users are forced to attempt to plug the cord in multiple times before finding the right direction and proper angle by using Micro USB cables.
There is a support for wireless charging for Galaxy S6 and Galaxy S6 Edge, which is better than Lightning, but there is still a Micro USB cable needed for some activities.
