New iPhone 13 bigger case VS iPhone 12

“You can see that the iPhone 13’s camera is a small turn larger than the iPhone 12, and then closer to the top left corner of the border. The position of the key moves down a little.” A third post reads:

iPhone 13 larger camera module

According to the images appear iPhone 13 Case includes larger camera lenses and a larger bump to house them: “The biggest upgrade to the iPhone 13 series looks like a camera, and after the Pro’s camera is about the same as the 13ProMax,  how do I feel like the high brush is just 13ProMax exclusive ah, otherwise the Pro is a little too showy”A third-party posted.

iPhone 13 could have a much larger camera module (previously seen in alleged leaked photos), even if the arrangement of lenses still looks identical.

As the measurements on the images show, the iPhone 13 Pro and Pro Max’s cameras could be around 78mm (0.3 inches) larger diagonally than the iPhone 12 Pro’s cameras, and just over half a centimeter (0.2 inches) larger as we can see from the iPhone 12 Pro Back camera module within this new case.

However, the size increase on the iPhone 13 and 13 mini looks to be just 0.27cm (0.1 inches).  iPhone 13’s rear cameras is diagonally oriented.

This also applies to the size of the glass in the lenses themselves. All the iPhone 13 handsets look to be gaining a few increments of an inch, but the biggest change again appears to be between the iPhone 12 Pro and iPhone 13 Pro, a difference of 3.8mm (0.1 inches).

Guess it based on the shell of the iPhone 13. The iPhone 13 and 13mini cameras are the same and get bigger, so the 13 camera ramps allow the camera area not to get bigger while maximizing space utilization. The aperture is about the size of the iPhone 12ProMax, so did the sensor inherit the iPhone 12ProMax? (The aperture of the shell will be a small circle larger than the phone camera)

iPhone 13 buttons moved

Checking out the case from the side also shows how the power and volume buttons and alerts slider could be coming further down the sides by 6.2mm (0.2 inches). This could be to make room for newer components within the phone, or as an ergonomic change to make it easier for users to access these buttons one-handed.
