Next, look at the camera part. Although the iPhone 14 Pro/Pro Max series is still a three-camera scheme with super wide angle+wide angle+telephoto, and equipped with a LiDAR lens, the main camera is upgraded to a brand-new 48-megapixel sensor for the first time, with a unit pixel area of 1.22μ M, supporting the four-pixel integration technology, and the unit pixel area can reach 2.44μ M, the lens aperture is f/1.78, the lens focal length is 24mm, and it is equipped with the second generation sensor displacement anti-shake technology. However, on the ultra-wide-angle and telephoto lenses, they still maintain 12 million pixels, the equivalent focal length of telephoto lens is 77mm, and the equivalent focal length of ultra-wide-angle lens is 13 mm.

In terms of camera module size, the camera module size of iPhone 14 Pro is slightly larger than that of iPhone 13 Pro.

Disassemble the camera module, you can see the main camera sensor of iPhone 14 Pro, and continue to adopt the sensor shift image stabilization system first introduced by iPhone 12 Pro series, which greatly improves the anti-shake performance. In terms of the size of the main camera sensor, the iPhone 14 Pro has been expanded from 1/1.67 inch of the previous generation to 1/1.31 inch.

Compared with the previous generation, the rear lidar module of iPhone 14 Pro only has a slight change in cable design.

Although the "Microcomputer Branch" does not indicate the suppliers of the lens module, image sensor and laser radar module of the iPhone 14 Pro series, according to the previous data, the rear lens module of the Pro series should be mainly supplied by Dali Light, and the image sensor is mainly supplied by Sony. The rear lidar module is mainly supplied by Sony. As for the front Face ID module, the Face ID of iPhone 13 series was previously supplied by Foxconn and LG Innotek, but the Face ID of 14 Pro series has been improved, so it is uncertain whether it will still be supplied by these two companies.

There is a dustproof and waterproof apron around the inside of the rear flash of iPhone 14 Pro, which is quite different from the previous generation. After violent disassembly, it can be seen that the rear flash of iPhone 14 Pro has changed from two bulbs in the previous generation to a big bulb, but Apple has divided it into nine parts, which can adaptively control the flash intensity, brightness and uniformity. Both have improved.

Although the motor size of iPhone 14 Pro has shrunk compared with the previous generation, the external specifications close to 0920 are still excellent.

The sub-board structure at the bottom is the same as the previous generation, which is integrated with barometer, two microphones and a charging port. There is a dustproof and waterproof rubber ring on the inner side of the bottom speaker window.

In terms of battery, the iPhone 14 Pro series is still an L-shaped battery. From the perspective of the National Bank version disassembled by "Microcomputer", the battery capacity of the iPhone 14 Pro is 3,200 mAh, which is 105 mAh higher than that of the previous generation. The supplier is Huizhou Desai; The battery capacity of iPhone 14 Pro Max is 4323 mAh, which is 29 mAh less than the previous generation. The supplier is Xinwangda.

There are some parts on the back shell of the iPhone 14 Pro series, and the structure has been slightly adjusted. The WiFi antenna and NFC antenna are integrated on a flat cable, and the physical buttons and wireless charging module are integrated as in the previous generation.

Summary:

Judging from the above disassembly report and the existing public information,Although the hardware configuration of the iPhone 14/14 Pro has not been greatly upgraded as that of the Pro series, its internal structure has been redesigned, and the "sandwich" design has greatly improved the maintainability.

Therefore,IFixit gave a high score of 7 (out of 10) for the repairability score of iPhone 14, which is also the highest score since iPhone 7. IFixit even said: "This is a big event, and Apple should make a major statement that the iPhone 14 has been redesigned from the inside out to make it easier to maintain."

Sam Goldheart of iFixit thinks: "In this era, product launch should not just brag about some small new features. Why doesn’t Cook brag about repairability? We didn’t know this would happen because Apple didn’t mention it at all. But they should do so. "

In addition, the two-way satellite communication function introduced by iPhone 14 series is also a focus of attention. The reason why the iPhone 14 series can support two-way satellite communication is mainly due to the upgrade of Qualcomm Snapdragon X65 baseband chip and Apple’s self-developed RF antenna.

According to previous data, Qualcomm Snapdragon X65 baseband chip can not only support the downlink rate up to 10Gbps, but also cover all major 5G bands including millimeter wave and Sub-6GHz band and their combinations. It is confirmed that the satellite communication of iPhone 14 series is supported by Qualcomm Snapdragon X65. The baseband chip has added a new 2.4 GHz n53 band function to support the satellite of Globalstar, a satellite communication company cooperated by Apple.

ICJay Monroe, executive chairman of Globalstar, boasted at the press conference earlier this year: "We appreciate the close relationship with Qualcomm since the company was founded, and thank their team for their hard work in helping us realize the promise of Band n53." Globalstar previously announced that it agreed to use 85% of its current and future satellite network capacity to support the two-way satellite communication function of iPhone.

In addition, the addition of two-way satellite communication function, coupled with many existing communication functions such as 5G, WiFi, Bluetooth and GPS, not only greatly increases the number of antennas, but also brings greater challenges to antenna design. During the disassembly, we also saw some new designs of Apple on the antenna.

Disassembly also shows that although the iPhone 14 Pro series still uses 6GB of memory, it uses the latest LPDDR5 technology, while the previous generation iPhone 13 series is LPDDR4X.

Earlier, Apple had indicated that it would not consider using Changjiang storage flash memory in iphones sold in markets outside China, so we didn’t see the version using Changjiang storage flash memory in the disassembly of the US version of iFixit iPhone 14 series.

However, the three National Bank versions of the iPhone 14 series dismantled by Calculus have not found any flash memory with Yangtze River storage. But,According to the disassembly video of the National Bank version of iPhone 14 Pro Max released by a domestic blogger, the disassembled version uses flash memory supplied by Changjiang Storage.

Judging from the changes in the supply chain of Apple’s iPhone in recent years, the proportion of Chinese mainland suppliers in the Bank of China version of iPhone is growing continuously.

This may also be a measure taken by Apple to reduce the supply chain risks caused by the "US-China science and technology war" and "geopolitical issues".
