- More aluminum: iPhone 17 Pro models are rumored to have an aluminum frame, whereas the iPhone 15 Pro and iPhone 16 Pro models have a titanium frame, and the iPhone X through iPhone 14 Pro have a stainless steel frame. The back of the devices will supposedly have a new "part-aluminum, part-glass" design. The frame could end up using a combination of both aluminum and titanium.
- Rectangular camera bump: On a related note, the devices are expected to have a "larger rectangular camera bump" made of aluminum. There are conflicting rumors about the camera lenses sticking with a triangular arrangement or being repositioned horizontally or vertically.
- A19 Pro chip: iPhone 17 Pro models are expected to use Apple’s next-generation A19 Pro chip, which will reportedly be manufactured with TSMC’s newer third-generation 3nm process. Like usual, expect modest year-over-year performance gains and power efficiency improvements compared to the current iPhones.
- Apple-designed Wi-Fi chip: At least one iPhone 17 model is rumored to get a Wi-Fi 7 chip designed by Apple rather than Broadcom. However, another report said the chip will support Wi-Fi 6E like iPhone 16 models.
- 24-megapixel front camera: All four iPhone 17 models are said to feature an upgraded 24-megapixel front-facing camera, whereas all iPhone 16 models are equipped with a 12-megapixel front-facing camera.
- 48-megapixel rear Telephoto camera: An upgraded 48-megapixel Telephoto camera is rumored for the iPhone 17 Pro models, up from the 12-megapixel Telephoto camera on iPhone 16 Pro models.
- 12GB of RAM: An increased 12GB of RAM was initially rumored exclusively for the iPhone 17 Pro Max, but later the iPhone 17 Pro as well. This upgrade should help to improve the performance of Apple Intelligence and multitasking. All four iPhone 16 models have 8GB of RAM.
- Improved cooling: All four iPhone 17 models are rumored to feature internal design changes that result in better heat dissipation.
