Huawei Mate 20 Pro Teardown

Last month Huawei held a new product conference and launched its new flagships – the Huawei Mate 20 Pro in London. The Mate 20 Pro is powered by the world’s first 7nm mobile AI chip- Kirin 980. Moreover, this flagship features the under-screen fingerprint reader. Today, let’s explore this amazing smartphone’ss internal structure and workmanship.

First of all, remove the SIM card tray. Its SIM card is the similar 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. And the light is connected to the motherboard via the cable. As for the wireless charging coil, it 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 a PCB are placed below the motherboard.

This flagship features Leica Triangle camera on the rear, including 40MP F/1.8 aperture wide-angle camera, 20MP F/2.2 aperture ultra wide-angle camera, and 8MP F/2.4 aperture telephoto camera. The Leica Triangle camera supports autofocus and AIS (Huawei AI Image Stabilization.

The part circled red is Kirin 980 chip and Samsung SEC828 K3UH7H7 memory chip (8GB LPDDR4X 2133MHz). The part circled green is Hisilion HI1103Wi-Fi chip which supports 802.11ac, 2×2 MIMO, and 160MHZ broadband. Besides, its speed reaches up to 1732Mbps. At present, this Wi-Fi chip reaches the top level.

The part circled red is Samsung SEC 822 BOC1 KLYDG4U1EA flash chip (128GB, UFS 2.1). And the part circled yellow is 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 supplier of Apple.

There are the components: 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 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. We can see 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 typical capacity is 4200mAh; its rated voltage is 3.82V, and limited charge voltage is 4.4V. Besides, its thickness is 4.49mm.

It’s a pity that I can’t show you the structure of its under-screen fingerprint reader. This fingerprint reader adopts Dynamic Pressure Sensing technology. With this under-screen fingerprint reader, the user can unlock its phone securely and quickly.


The Huawei Mate 20 Pro had the best craftsmanship among all Huawei’s smartphones. It boasts flagship-level components and internal structure. Although the Mate 20 Pro has a complicated internal structure, its teardown process is simple.
