Upgrading to a new iPhone always comes with the question of whether old accessories will still work. Cases are no exception, and many wonder if they can reuse one from a previous model. Will an iPhone 13 case fit the iPhone 15? No, it won't.
While both phones have a 6.1-inch display, Apple made several small but important design changes that make older cases incompatible. The iPhone 15 has a more rounded shape, a larger camera bump, slightly different button placements, and a USB-C port instead of Lightning.
These differences mean an iPhone 13 case won't fit securely or function properly. In this article, we'll break down exactly why that is and what to look for when choosing the perfect case for your iPhone 15.
Will an iPhone 13 Case Fit the iPhone 15?
The short answer? No, an iPhone 13 case will not fit an iPhone 15 properly. This is a similar issue to figuring does an iPhone 14 Pro Max case fit a 15 Pro Max. At first glance, these two models may look similar. They both have a 6.1-inch display, and their overall dimensions appear close.
However, Apple made several design changes to the iPhone 15 that prevent an iPhone 13 case from fitting correctly. Here's why:
Rounded Edges And Shape Differences
The iPhone 15 features a more rounded design compared to the iPhone 13's flat-edged aesthetic. This subtle change means an iPhone 13 case won't sit flush against the iPhone 15, leading to potential gaps around the edges.
From our research, we know that a case that doesn't fit snugly can reduce protection and make your phone more vulnerable to damage.
Camera Bump Changes
One of the most noticeable differences is the larger camera bump on the iPhone 15. The cameras are positioned differently compared to the iPhone 13, meaning an iPhone 13 case won't align properly, much like with the issue of will an iPhone 12 case fit an iPhone 15.
After putting this to the test, we've found that if you try using an old case, you may find that the camera cutout is either too small or misaligned, which could obstruct the lenses or flash.
USB-C Charging Port
With the iPhone 15, Apple finally made the switch from the Lightning port to USB-C. While this won't affect case fit in most cases, some iPhone 13 cases have precise cutouts for the Lightning port that may not align well with the new USB-C connector.
Button Placement Adjustments
In our experience, Apple often makes subtle adjustments to button placement, and the iPhone 15 is no exception. Even if an iPhone 13 case physically fits around the phone, the button cutouts may be misaligned, making it difficult to press the volume and power buttons comfortably.

Conclusion
The iPhone 13 and iPhone 15 may look similar, but the differences in shape, camera bump size, button placement, and the switch to USB-C mean an iPhone 13 case won't provide the right fit or protection.
