Although Apple officially released the iPhone 12 series on October 14, it didn't officially launch the iPhone 12 Pro Max until the beginning of this month, and due to supply problems, it may take 3-4 weeks after placing an order online.

Recently, ifixit, a professional dismantling organization, has also disassembled the iPhone 12 Pro max.

First, let's review the configuration of the iPhone 12 Pro max. Compared with the previously disassembled iPhone 12 pro, the screen size of the iPhone 12 Pro Max is further increased to 6.7 inches with a resolution of 2778 x 1284.

The other major difference is that the rear image system, which is equipped with 12 million pixels of rear-view cameras and LiDAR scanners, is larger iPhone 12Pro Max the sensor size, reaching 1.7 percent

At the same time, the iPhone Pro Max also has a stronger equivalent 65mm telephoto lens (the iPhone 12 Pro is also the equivalent 52mm telephoto lens), and the entire imaging system can support 5 times optical zoom.

Green is iPhone 11 Pro max, gold is iPhone 12 pro and blue is iPhone 12 Pro max. It's obvious that the iPhone 12 Pro Max is bigger, and it's the largest iPhone yet.

Because the iPhone 12 Pro Max provides a stronger post camera system, the rear camera is also more convex than the iPhone 11 Pro max.

After heating the iPhone 12 Pro max, the back cover can be easily removed through the suction cup.

In terms of appearance, the layout of the rear camera and lidar module of the iPhone 12 Pro Max is very similar to that of the iPhone 12 Pro Pro max, except that the wide-angle camera of the iPhone 12 Pro Max is larger in size and slightly different in the cable layout design.

Through X-ray, we can see that the iPhone 12 Pro Max rear wide-angle camera is equipped with a larger image sensor, and there are four small magnets around it. This is Apple's new sensor shift image stabilization system, which can better achieve anti shake.

After separating the wide-angle lens of the iPhone 12 Pro Max from the sensor, we can clearly see the larger image sensor.

The area of the sensor for the iPhone 12Pro Max wide-angle lens has increased by 47%(compared to iPhone 12Pro), according to official data, from 12 million pixels to 1.7% for a single pixel

In addition, we can clearly see the image stabilization system by shifting the sensor of the wide-angle lens of the iPhone 12 Pro max. This is the technology used in many modern digital SLR cameras and reflectorless cameras.

At present, there are two main methods to stabilize the image: moving the lens or moving the image sensor. Most of the smart phone anti shake system is based on the optical image stabilization function (OIS) of lens to eliminate jitter. Apple is the first to apply image stabilization system based on image sensor displacement to smart phones.

With the current trend of many Android mobile phone manufacturers pursuing multi camera and high pixel (many of them are up to 100 million pixels), apple is really independent. Although the rear camera has been upgraded to three cameras, the pixel is still 12 million pixels.

iPhone 12 series of battery capacity has been criticized by the outside world. Only iPhone 12Pro Max have been used compared to the previous iPhone 11 series

The battery capacity of iPhone 12 Pro Max is 14.13wh, while that of iPhone 12 and iPhone 12 Pro is only 8.57wh and 10.78wh respectively. However, the iPhone 12 Pro Max is still smaller than the iPhone 11 Pro Max's battery capacity (15.04 wh).

Compared with the main board (bottom) of the iPhone 12 mini, the structure of the main board (upper part) of the iPhone 12 Pro Max is more compact. Of course, the main board of the iPhone 12 Mini is also integrated with a SIM card reader, which makes the motherboard larger. The other three iPhone 12 series have separate SIM card reader designs.
