For a long time there were numerous rumors that the iPhone 13 will be portless and will only support wireless charging. This may be generally true as the iPhone 13 will have a larger charging coil compared to the previous model. However, the biggest difference would be that the iPhone 13 would have a faster charge and a reverse charge.
With a larger coil, the iPhone 13 will be able to handle heat better and therefore allow for higher power. Also, the addition of reverse charging would be new for the iPhone as Android devices have been using reverse charging for quite some time. However, a larger coil would result in a larger but also improved MagSafe.
According to the filtered image below, the camera settings will be similar to the previous model but the overall size of the phone would be larger than the iPhone 12 line.
