Based on these images, it appears that the iPhone 15 Ultra's camera bump will measure 3.78mm. While that is still .40mm or 9.6% thinner than the camera bump on the iPhone 14 Pro Max, it is .19mm or 32% larger than the iPhone 15 Ultra camera bump tweeted by Ice Universe.
ShrimpApplePro also says that the diameter of the rear flash will be slightly smaller at 6.7mm on the iPhone 15 Ultra compared with the 6.9mm diameter on the iPhone 14 Pro Max. The diameter of the microphone will decline sharply from 1.15mm last year to .75mm this year and the size of the Dynamic Island will stay the same.
The CAD images also show the solid-state buttons for the iPhone 15 Ultra. These buttons will replace the mechanical volume buttons found on past iPhone models and might even include a user programmable action button like the one on the Apple Watch Ultra. These solid-state buttons will give haptic feedback when touched to mimic the feel of pressing a real mechanical button.
If the solid-state buttons feel the same and do the same things as mechanical ones, what is the point of using them you might ask? Well, the solid-state buttons won't give in to wear and tear and are less likely to break.

ShrimpApplePro also found some type of padding on top of the solid-state buttons that will help the buttons work with some phone cases. Since the padding is also found on the iPhone 15 and iPhone 15 Plus, the tipster believes that the two non-Premium models will also have solid-state buttons but with two separate ones for volume up and volume down. The premium models like the iPhone 15 Pro and iPhone 15 Ultra will have one solid-state volume button that is pressed on top to raise the volume and pressed on the bottom to lower it.ncG1vNJzZmivp6x7sbTOp5yaqpWjrm%2BvzqZmp52nqHykrcyeqZplkqq6sXnDnpqloZ6aeqq8x6ilnmVhanq2uNOrmJihlGaBd4OWbQ%3D%3D
