The Vivo X21 is designed with a full metal body design, and the SIM card slot is located below the body. We first remove the card slot and then remove the two screws below the body with a screwdriver.
Next, the heat shield is uniformly heated on the screen, then gently inserted into the screen and the slit of the screen with the rocker, be careful, and then the screen cover is separated from the right side. Since there is no fingerprint recognition, the rear shell can be separated directly.
The ferrous design of the metal back sheet adopts a thick design, and the back black area is a large-area graphite heat. In this case, the foam frame ensures that the battery is not in contact with the back shell, ensuring the safety of the battery.
Next, we discharge the main board cable, open the graphite cooling on the shield, and the heat dissipation paste is also designed, and the design of double heat dissipation seems to be very useful for temperature control. Next, we disconnected the screen from the disconnection, the bottom PCB cable, Vivo x21 This time, all the cable connection ports are designed, and the waterproof is further strengthened.
Remove all screws and cables, the motherboard can be separated from the body. We can see that Vivo X21 is very particular about the body structure or the row.
We give the motherboard a close-up, the gap on the left is the back double-photographing area. Vivo x21 is equipped with the Snapdragon 660 AIE processor. From the actual run points, Xiaolong 660 is close to the performance of the Snapdragon 820 of the upper generation 800 flagship, and has a better performance in multi-core, both daily use. Or large games are not here.
After opening the motherboard protective cover, all the original is completely presented in front of us. This X21 UD has 6GB of storage, 128GB storage space, next to communication amplifier and radio frequency transceivers.
Next, let's take a look at the back double-timer group of X21. In terms of photographing, Vivo X21UD uses 2X12 million pixel sensors to support full-pixel dual-core speed focus, with 24 million photosensitive units. Even if you encounter a backlight scene, you can shoot a clear and bright picture.

Next, let us continue to disassemble the battery, etc., the Vivo X21 is a lithium ion polymer battery, typical capacity 3200mAh, 11.85Wh, a platform voltage 3.85V, and the charging limit voltage is 4.4 V. Vivo X21 fast charge, matching the original charger, achieving a fast charge of 18W 9V2A.
Next, we remove the bottom module of the body and remove the screw to remove the speaker portion. The speaker comes from Apple's ACC, the blue part is to make the sound sound a clearest patent design. The white block below is the handset, it looks very small.
In terms of vibrating motors, Vivo X21 uses traditional rotor vibrating motors, which should be saved, so vibration feelings must definitely be more than apple Tapic Engine.
It is roughly here to discover the machine, and from the overall design and workmanship, Vivo X21 is still very useful in design. Whether it is a beautiful internal trace, a solid workmanship, as well as the waterproof design of the people, reflects the use of Vivo everywhere.
