One plus 8t is a flagship new product launched by Yijia in the second half of 2020. The combination of 4500mAh large battery and 65W fast charging can meet the daily needs of users. The flagship hardware with 188g and 8.4mm fuselage also achieves a smart balance from performance to experience. Most importantly, as a “super flagship of the screen”, one plus 8t also promotes the ecological development of high frame content through a 120Hz direct screen.
One plus 8t
How about the performance of the internal process details? Today, we will take one plus 8t apart to see if its internal structure meets the high standard of the flagship.
Remove the SIM card holder
Before dismantling the one plus 8t, we need to turn it off and remove the SIM card holder. The card holder is located at the bottom of the body and has a dust and water-proof rubber ring inside, which can prevent dust or moisture from entering the phone from the SIM card slot, thus affecting the use.

Slide around the phone and cut the glue
The same as the previous one plus mobile phone, the one plus 8t still adopts sandwich structure. We can place it on the heated platform that has been preheated. After feeling the phone is slightly hot, use a crowbar to pry a small gap at the bottom first, and then use the stripper to slide around the mobile phone to cut the glue. 8t can be seen in the bottom of the mobile phone, and the amount of glue can be greatly improved in the bottom of the phone.

Corresponding opening of camera, flash lamp and other elements
This time, the interior design of the one plus 8t rear cover is relatively simple. The design of cushion foam can reduce the damage caused by impact on the mobile phone. With the design of heat dissipation film, the heat inside the body can also be distributed to the outside of the body as soon as possible. On the top of the back panel of the mobile phone, the corresponding holes of the camera, flash, and back photosensitive components can also be seen.
Disassembly of main board
After the rear shell is disassembled, the main body with 8t will be displayed in front of us. It is not difficult to find that the interior design of one plus 8t still uses the traditional three-stage structure. Of course, because this time, the position of the four pictures on the back is moved from the middle to the left, so the overall design of the motherboard is also slightly adjusted.
After removing the nine screws that fix the cover plate, we can remove the cover plate of the motherboard. The main board cover has a heat dissipation film inside, and an NFC coil is pasted on the outside, which is convenient for us to simulate the mobile phone as a bus card and other NFC cards. In addition, a 8t back brightness sensor is also hidden next to the camera module. It supports the highest 8192 level brightness adjustment in Android camp, which can ensure a smooth transition of screen brightness.

Disassembling the front lens
Close up of front camera
After removing the cover plate of the motherboard, we can remove the 16 megapixel front lens and the back four camera module by uncoupling many cables connecting the motherboard. This time, the 1 + 8t front lens uses 16 megapixel Sony imx471, the same as one plus 8. The back four shots are 48 million pixel main camera (imx586) + 16 million pixel ultra wide angle lens + 5 million pixel macro lens and 2 million pixel black and white filter lens. The parameters of the main camera are the same as one plus eight. Of course, the four lenses are fixed together, which ensures stability to a certain extent.
Disassembly of one plus 8t mainboard
Close up of one plus 8t motherboard (covered with heat dissipation sticker)
After removing the screws fixing the motherboard and the coaxial line in turn, you can see a motherboard with 8t. Overall, one plus 8t motherboard is highly integrated, with thermal stickers covering both sides. Moreover, Yijia official has prepared extra heat dissipation silicone grease for SOC, which can ensure that the heat of the whole machine can be quickly distributed to the outside of the fuselage.
The BTB connector is provided with protective rubber ring
It is worth mentioning that many BTB connectors are equipped with protective rubber ring, which can greatly reduce the damage to the important components in the body after the mobile phone is flooded.
To further disassemble the motherboard, we need to remove the heat dissipation stickers on both sides of the motherboard. In order to further improve the heat dissipation capacity, the surface of each internal component of one plus 8t is covered with silicone grease. Such solid materials also lay a solid foundation for good heat dissipation effect. In addition, we can also see the distance sensor with integrated light sensor, top speaker and so on.
Disassemble the protection plate of the auxiliary plate
After the top main board is disassembled, we will dismantle the lower sub board. First, remove the screws on the surface in order to remove the sub panel protection board of the integrated loudspeaker, and then successively disassemble the cable and coaxial line interface, and then remove the sub board after unscrewing two screws.
Disassemble the secondary plate
The sub board is integrated with microphone and SIM card slot. After the sub board is removed, the type-C interface cable can be taken out. It can be seen that there are red aprons on the surface of type-C interface and speaker position of one plus 8t, which can also prevent dust and moisture from entering the mobile phone and affecting the use.
Type-C interface surface and speaker position are covered with red rubber ring
After further disassembly, we can also see an X-axis linear motor with an additional 8t. It is the small linear motor at the bottom, which provides us with a more real sense of vibration.
Here’s the final step of dismantling the battery. One plus 8t battery also has a quick detachable design, which only needs to pull two batteries
