The first detailed teardown of the iPhone 12 and iPhone 12 Pro is officially here from iFixit and if you wanted a closer look at the internals, this is the place to be. According to the findings listed from the disassembly process, it was found that Apple is using similar components for both models while pricing them differently. Here’s a more detailed read on what exactly we mean by that.

It looks like the 6.1-inch display size isn’t the only thing that Apple decided to keep consistent between the iPhone 12 and iPhone 12 Pro. Though the iFixit teardown reveals some changes like the size of the Taptic Engine and that extra camera coupled with the LiDAR unit on the iPhone 12 Pro, there are some interchangeable components for both models. For example, both the iPhone 12 and iPhone 12 Pro feature the same 2815mAh battery, as well as the same display.
