Having torn down the base iPhone 12 and the Pro model, iFixit has since broken down the mini variant. And this teardown reveals the components that Apple shrunk for it to fit in the much smaller frame.
To start, the display of the iPhone 12 mini is, obviously smaller than the base model. To recap, the base model came with a 6.1-inch 2532 × 1170 screen, the mini instead comes with a 5.4-inch 2340 x 1080 screen instead. In addition to that, the screen itself is connected with two display cables. This is opposed to three on the standard model.
The next component to be shrunk is the battery. The mini comes with a 8.57Wh battery, as compared to the 10.78Wh one in the base model. Beyond that, even the Taptic Engine is about 25% smaller. But despite the smaller size, it’s still fit “snugly”, leaving no space for anything else, like a 3.5mm audio jack.
As with the base iPhone 12, the mini variant also gets a 6/10 repairability score. Most of the positive, as well as negative, points from the base device applies here as well. The folks don’t have a video of it this time, but you can still read the detailed process by following the link below.
