The Huawei Mate RS was officially launched on April 14, 2018. With its outstanding appearance and excellent performance, this phone has attracted attention from the public. Today, we will start the teardown of the Huawei RS to explore its internal structure and craftsmanship.
First of all, remove the SIM card tray. Heat the back cover for five minutes before taking it out. The top and bottom of the back cover are secured by glue, so we need to be careful when removing the back cover.
The back cover can not be completely separated from the phone body since the fingerprint cable is still connected to the motherboard. White super glue tightly secures the back cover to the phone body, and at the same time, this glue ensures the back cover has good sealing performance.
The fingerprint scanning chip shows that this scanner is made by one of the top-level biometric manufacturers, Goodix. This manufacturer is also reported to provide the front under-display optical fingerprint sensors.
There is no other electrical component integrated into the back cover except the fingerprint reader module. The motherboard is covered by thermal material to avoid heat congregation, and a layer of foam is filled in the gap between the battery and the back cover.
Even after removing the wireless charging coil, the battery still cannot be seen since a graphite sticker is placed between the coil and the battery. Such a design is to avoid high temperatures in some areas since the coil and battery will generate heat during the wireless charging process.
Before removing the plate on the top, we need to remove the LDAF module from the camera, and the cable will need to be disconnected. We also need to remove the LED detection module.
The right part of the plate is covered by thermal grease, which is used to help with heat dissipation for the chip. The connector uses a foam pad design to prevent poor connections.
Next, disconnect the sub-board ribbon cable, button cable, display cable, and touch cable from the motherboard.
It is reported that all three cameras of the Huawei Mate RS support optical image stabilization. However, testing has revealed that only the telephoto lens supports optical image stabilization technology, while the other two lenses do not have this feature.
Although the front camera is smaller than the main camera, it is not small compared with other front cameras. As we all know, this smartphone features a 24MP front camera with an F/2.0 aperture.
Most of the chips used in the Huawei RS series are the same as those on the P20 Pro. The motherboard of this phone is smaller than that of the P20 Pro, and the circuits on the motherboard are well protected.
There are three main chips integrated into the back of the motherboard, including the RAM, processor, and ROM. The memory chip and the AI Kirin 970 processor are sealed together. For battery charging management, the device adopts the mainstream Texas Instruments BQ25892 chip.
The power management chip and a lot of filter capacitors are placed on the front of the motherboard.

We found that the design of this phone is better than the iPhone X. Chips that generate a lot of heat are placed on the outer layer of the motherboard. This way, thermal materials can be used to help these chips get better cooling performance. The iPhone X even puts the processor on the inner layer of the motherboard.
Then, remove all the screws which are used to secure the modules at the bottom of the phone body. The vice board is also fully utilized to save space at the bottom of the phone. Two microphones have been integrated into the vice board. Metal contacts at the bottom are connected to a vibrator, loudspeaker, and antenna. Take out the loudspeaker module. The foam around the module is to prevent water from entering inside.
A red rubber is placed around the port of the loudspeaker. The dust-proof mesh is made of a glossy surface and tightly woven material, which is believed to be similar to the material used in the Samsung S8. This material can block external moisture while allowing air to circulate without affecting sound quality.
The loudspeaker is made by AAC Technologies Holdings Inc. It has excellent low-frequency performance.
To make the next teardown easier, we heat the screen first. Then, we use a thin plastic tool to remove the battery. The battery gets deformed. A large amount of glue is applied to the bottom of the battery. In addition, the display cable is located under the battery. Be careful during operation to avoid tearing the display cable.
Now, the battery has been successfully removed. It has a capacity of 4000mAh and supports 25W low-voltage fast charging technology. Even though this battery has a large capacity, it can be fully charged within two hours.
It takes us a longer time to tear down this phone than other Android smartphones. This phone has a complex design on the upper part. After this teardown, we saw an all-new internal design. This phone also has excellent heat dissipation performance and good sound.
According to the display cable, we know that the screen of this phone is provided by LG.
In general, the Huawei Mate RS is one of the smartphones in China with a superior internal design. Although its price may scare away many people, the craftsmanship of this phone has undoubtedly reached the top level in China.
