According to information resource that is well versed in WPC, wireless charging function that is built in iPhone 8 going to be announced in September has a possible of 7.5 W specification at maximum. It has been handling charging 15 W at maximum from Qi version 1.2. But Apple supports not Extended Power Profile 15 W but Standard Power Profile 7.5W(5V/1.5A), which is half.
The site also speculates that despite adhering to the Qi standard, the iPhone 8 may only support wireless charging equipment that is MFi certified.
The iPhone 8 will be Apple's tenth anniversary smartphone. It's believed to feature an edge-to-edge 5.8-inch OLED display with a notch in the bezel at the top for the earpiece and front facing camera. It will use a virtual Home button in place of the traditional physical Home button at the bottom of the device. The device will purportedly incorporate a revolutionary 3D sensor that is years ahead of the competition to enable facial recognition and augmented reality features. It's also said to feature a glass back to facilitate inductive wireless charging. The latest reports claim Apple was not successful in embedding Touch ID under the display and so the iPhone 8 will only feature Face ID (Pearl ID) for biometric security.
Apple is expected to offer the iPhone 8 in black, silver, and gold (copper?) colors and 64GB, 256GB, and 512GB storage capacities, all with 3G of RAM. Carrier sources say Apple will unveil its new iPhones on September 12th and release them on September 22nd.
