A previous teardown of the iPhone 12 and iPhone 12 Pro has revealed that the interior structure and appearance of the two iPhone models is quite similar. Therefore, the experts over at REWA Technology tried to swap some parts of the two models to test if they can be functionally interchangeable.
During their test, one interesting finding that has come to light is that Apple is using iOS to limit the maximum screen brightness of the iPhone 12. Apple’s website notes that the iPhone 12’s maximum brightness is 625 nits whereas the iPhone 12 Pro’s maximum brightness is 800 nits.
But when the iPhone 12’s display is put inside the iPhone 12 Pro, its maximum brightness goes all the way up to 800 nits. Similarly, the maximum brightness on the iPhone 12 Pro’s display gets limited to 625 nits when placed inside the iPhone 12.
The test pretty much confirms that Apple is using the software to limit the maximum screen brightness of the iPhone 12, although it remains unknown as to why the company is doing so.
Check out the video below and take a look at the screen brightness limit in the iPhone 12.
