Wireless charging option is feature which is liked by more and more people. Wireless charging is definitely more comfortable than standard charging, but the main disadvantage of this feature is long charging time of our devices. Recently Apple released an update of iOS which allows to charge some phones in faster way with using wireless loaders.
iOS in 11.2 version causes that iPhone X, iPhone 8 and iPhone 8 Plus may be charged up to 7.5W. Still it's not as fast as Samsung's charger (which can reach up to 15W), but in future Apple definitely wants to fight with Samsung in this topic.
