Last month, Huawei held a new product conference in London to launch the Huawei Mate 20 Pro. The Mate 20 Pro is powered by the world’s first 7nm mobile AI chip, the Kirin 980. This phone features an under-screen fingerprint reader. Today, let’s explore this amazing smartphone’s internal structure and workmanship.
First of all, remove the SIM card tray. Its SIM card is similar in size to the iPhone XS Max’s and the OPPO Find X’s. The red rubber is waterproof. We use a heat gun to heat the verge of its back cover. Then, we use a suck to separate the back cover from the phone body.
The four angles of the back cover are well protected by white glue. Now, we can see that the phone adopts a classic three-stage internal design. Its battery and vice board are covered by the wireless charging coil. The top and bottom parts are placed with some special material to be waterproof.
From the picture, we can see that the fill light is fixed on the plate. The light is connected to the motherboard via the cable, and the wireless charging coil is connected to the motherboard via the metal contacts.
Its three cameras are connected to the motherboard via two cable connectors. One connector circled as red is fixed on the metal plate. The 3D depth-sensing camera system, speaker, and PCB are placed below the motherboard.
This phone features a Leica Triangle camera on the rear, including a 40MP F/1.8 aperture wide-angle camera, a 20MP F/2.2 aperture ultra wide-angle camera, and an 8MP F/2.4 aperture telephoto camera. The Leica Triangle camera supports autofocus and AIS (Huawei AI Image Stabilization.
The part circled red is the Kirin 980 chip and Samsung SEC828 K3UH7H7 memory chip (8GB LPDDR4X 2133MHz). The part circled green is the Hisilion HI1103 Wi-Fi chip, which supports 802.11ac, 2×2 MIMO, and 160MHZ broadband. Its speed reaches up to 1732Mbps. At present, this Wi-Fi chip reaches the top level.
The part circled red is the Samsung SEC 822 BOC1 KLYDG4U1EA flash chip (128GB, UFS 2.1). The part circled yellow is the HI6422GWC power chip. The part circled blue with HI6422 on it, and we suppose it is a power management chip. Its speaker is made by AAC.
The components are: A: laser sensor; B: 24MP camera (F/2.0 aperture); C: proximity sensor; D:ambient light sensor; E: infrared flash; F: an infrared camera.
The white particles in the blue dot can improve the phone’s low-frequency performance, which is ACC’s patent technology. The HTC U12+ adopts a similar design.
Disconnect the cable between the motherboard and vice board. The USB Type-C charging port is designed with white rubber, preventing water and other materials from entering.
Now, we will take out its battery. This battery cell comes from ATL, and the battery is assembled by Huizhou Desay Battery Co., LTD. Its rated capacity is 4100mAh, and its typical capacity is 4200mAh; its rated voltage is 3.82V, and its limited charge voltage is 4.4V. Besides, its thickness is 4.49mm.
Unfortunately, I can’t show you the structure of its under-screen fingerprint reader, which uses dynamic pressure-sensing technology. With this reader, users can unlock their phones securely and quickly.
Summary
The Huawei Mate 20 Pro has the best craftsmanship among all Huawei smartphones. It boasts flagship-level components and internal structures. Although the Mate 20 Pro has a complicated internal structure, its teardown process is simple.
