It's not clear if the wireless charging modules will actually make it to the "iPhone 8" -- still a year away -- but there is testing underway. Sources speaking to Nikkei said it "will depend on whether Foxconn can boost the yield rate to a satisfactory level later on".
Wireless charging, available on many popular Android handsets, has been long requested by the iPhone-camp. It's not clear if all versions of the 2017 iPhone would have the feature.
Bloomberg previously reported Apple is developing wireless charging technology for the iPhone by 2017.
Previous reports indicate the iPhone 8 will have three different versions, including a curved 5.5-inch handset. Apple is suggested to replace the metal casing with a glass back.
With all rumors, we suggest you stay skeptical. Product launches often change, and Apple is known to hold out on what seem like obvious features.
Apple released the iPhone 7 in September, with camera, speed, and software improvements at the focus.
