It looks like both Apple and Samsung will be adding wireless charging capabilities to iPhone 5S and Galaxy S4 this year. Sources say that the next-generation iPhone will use wireless charging technology developed by Apple. At this time no one knows if the charger will be built with the wireless charging feature or rely on an attached accessory.
Samsung’s Galaxy S4 is expected to support the Qi wireless charging technology. The S4 may not include the capability itself but instead require users to buy a back cover that can access a charging pad.
