iPhone 12 vs. iPhone 12 Pro: Parts Swapping Test by REWA LAB

Recently, REWA LAB found that the interior structure and appearance of the iPhone 12 between iPhone 12 Pro look very similar after teardown. Therefore, REWA technicians tried to swap some parts of the two models to test if they can be functionally interchangeable. Want to find out the test result? You will see it by reading this blog!

One of the most identical difference is that iPhone 12 have one less camera. According to official information, the max brightness of the iPhone 12 is 625 nits while the max brightness of the iPhone 12 Pro is 800 nits. After the test by found the max brightness of the iPhone 12 is 625 nits while the iPhone 12 Pro is 800 nits. The reason may be related to the screen or the motherboard.

Lift the screen and we can find the interior parts of the iPhone 12 and iPhone 12 Pro are arranged basically in the same way except for the rear camera bracket. Remove the display, we can see that the displays and flex cables have the same look. Now, swap two screens, assembly the phone, and start testing. Boot up and the screen works well. “Important display message” and “Unable to activate Face ID on the iPhone” pops up which indicates that the display has encrypted IC. 3D Touch and touch function work well while the “True Tone” function lost. Test distance sensor on the ear speaker flex and ambient light sensor on the ear speaker and all function works normally. These tests prove that sensors on the ear speaker are interchangeable except for the encrypted flood illuminator of the Face ID module. The max brightness of iPhone 12 Pro becomes 809nits with iPhone 12’s display while the ma brightness of iPhone 12 becomes 618 nits with iPhone 12 Pro’s display. It can be seen that the max brightness of the two models not related to the display. The reason may be related to the motherboard or iOS system. Generally, the two models’ displays are interchangeable.

Moving to other internal parts, we can find two models’ speakers have the same look and size as well. Two Tactic Engines present the same appearance and size. After the swapping of Tactic Engines, the vibration function works well. Let’s see what will happen after the battery swaps. “Important battery message” pops up which indicates that BMS used in battery feature an encrypted IC. However, the phone still can charge normally.

Next, let’s take a look at the lightning connector flex cable. The appearance of both is the same. After the swapping test, we find recording function and charging function all work normally.Finally, we found that in addition to the camera and the motherboard, almost all parts of the iPhone 12 and iPhone 12 pro are compatible.
