Recent rumors about the upcoming iPhone 18 Pro and Pro Max suggest that Apple is planning to introduce a new rear design with a transparent lower part. This design tweak is said to be inspired by Nothing, but Apple is unlikely to confirm this. The front-facing camera hole-punch is also rumored to be smaller, with an under-display Face ID sensor array. The screen shape will reportedly change slightly, while the main camera will feature variable aperture. Despite these changes, the camera island design is expected to remain the same. Additionally, the iPhone 18 Pro Max is rumored to have a steel shell encasing its battery.
It's important to note that these details are based on rumors and should be taken with a grain of salt. With 10 months until the iPhone 18 series is expected to be unveiled, more information is likely to emerge in the coming months.
