We ordered the Oneplus 5 in the morning, just after 5 hours has received the smartphone, I had to say the speed of the courier is really fast.
Well, let’s take a look at the specifications of this Oneplus 5
Qualcomm MSM8998 Snapdragon 835 (Octa-core (4×2.45 GHz Kryo & 4×1.9 GHz Kryo)
5.5 inch AMOLED capacitive touchscreen, 16M colors, 1080 x 1920 pixels (~401 ppi pixel density)
6GB RAM, 64GB ROM
Rear camera: Dual 16 MP, f/1.7 + 20 MP, f/2.6, phase detection auto focus, 1.6x optical zoom, dual-LED flash
Front camera: 16 MP, f/2.0
Dual Nano-SIM, dual stand-by)
Oxygen OS base on Android 7.1.1 (Nougat)
I tried to use the sucker tool to remove the back cover, but the attempt was failed.
So I insert a crowbar between the back cover and the fuselage, and slide the crowbar along the display edge to release the back cover from the fuselage.
After open the back cover, in this step you cannot remove the back cover completely, because there is a cable still connecting to the motherboard.
Remove one screw securing the metal plate that securing the battery connector and USB-C cable.
Disconnect the battery connector first and then disconnect the USB-C cable.
Huawei P10 uses a one-piece metal back cover, using a large area of nano-injection antenna to ensure a good signal overflow.
We can see the USB Type-C port and headphone jack are fixed on the back cover, and there are many metal contacts on the back cover.
Remove all screws securing the motherboard.
We can see the metal shield covering a layer of graphite stickers.
The battery and the motherboard do not cover with graphite stickers and now many mobile phones use graphite stickers to cover the motherboard and battery.
The Oneplus 5 comes with a 3.85V, 3300mAh Li-polymer battery, the battery model is BLP637.
It is worth mentioning that, Oneplus 5 did not upgrade the fast charge function, it is still use the 5V, 4A DASH fast charge.
According to the disassembly process of the OnePlus 5, we can find that the smartphone’s internal structure has adopted the systematically sealing design including sealing on the USB-C port. The phone’s back cover is also sealed by foam cotton. And other internal parts have also adopted the sealing design. Among all the smartphones I have disassembled before, only smartphones from Apple, Samsung, OPPO and Vivo manufacturers have applied such a strict sealing design and have gone through thickening process on their back corners. Even so there still exist some weaknesses on the phone’s internal design. The smartphone’s some connectors have not been fixed by metal plate and its camera connector is easy to go loose.
