Based on the size specifications that Apple has revealed on the iPhone 15 series, people can easily guess that using the case for the iPhone 15 series will be different from the iPhone 14 case. You can see the specifications of the iPhone 15 series below.

As you can see, based on the size specifications between the iPhone 14 and iPhone 15 series, they are completely different and therefore, you cannot use an iPhone 14 case for the iPhone 15 series.
While the differences between these specs aren't huge, iPhone cases are typically manufactured with such precision that even those small differences are enough to tell you that a case designed for the iPhone 14 won't fit the iPhone 15.
There are also other design changes that will make your iPhone 14 case incompatible with the iPhone 15:
- All iPhone 15 models feature rounded edges, meaning the edges of the phone now flow more seamlessly into the back.
- iPhone 15 Pro has an Action button instead of a silent switch
- The iPhone 15 Pro has thinner bezels around the screen.
Based on the details above, you can know that the iPhone 14 case will not fit any iPhone 15 series case.
