The first thing that stands out from the mini iPhone 12 teardown is the smaller 8.57 Wh battery. iFixit notes that its capacity is actually greater than that of the larger 2020 iPhone SE, which has a 6.96 Wh battery. As expected, however, it lacks the 10.78 Wh battery found in the iPhone 12 and iPhone 12 Pro.
The teardown also reveals that Apple included some iPhone 12 components in the iPhone 12 mini, but in smaller versions to save space, including the Taptic Engine, speakers, and the MagSafe ring. The cameras, on the other hand, are the same ƒ / 1.6 wide-angle and ƒ / 2.4 ultra-wide-angle cameras as those on the iPhone 12. The wide-angle module also has optical image stabilization.Elsewhere, Apple is removing the plastic standoffs found in the iPhone 12 due to the tight spaces inside the camera shield, but otherwise the layout of the components on the L-shaped motherboard is very similar.

Like the iPhone 12 and iPhone 12 Pro, the iPhone 12 mini achieved a repairability score of 6 out of 10. iFixit said many components are modular and easy to replace, but the site lamented the use. Apple continues of proprietary screws, the devices ‘waterproofing increases that can complicate repairs and increased risk of breakage due to glass on the front and back of both devices’.
