According to the Japanese resource Macotakara, iPhone 11 can get the function of wireless recharging Apple Watch and AirPods.
According to the forecast of Japanese blog, which often publishes reliable information about development devices, the next generation of iPhone will get the function of reverse charging. It is assumed that he will be able to share the charge, not only with Apple Watch and AirPods, but also with a new case for AirPods. The idea is that the iPhone battery is large enough to at least recharge the case without using cables.
Information from Macotakara is confirmed by analyst Ming-Chi Kuo and his report. He also believes that the next-generation iPhone will be able to charge devices wirelessly.
The report also says that Apple may add a new 18-watt charger, which is currently supplied with the iPad Pro or sold separately – this will increase the charging speed. Rumors about which power cable will be bundled with the iPhone 2019 are less specific. But Macotakara is inclined to believe that Apple will continue to use the cable with a Lightning connector. However the other side of the cable will be USB C, this will not only add native connector support to MacBook series but also will fit that iPad charger connector.
