OnePlus 5 Teardown

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

We also disassembled the OnePlus 5T and OnePlus 5T. Please click the link to access its teardown.

Powered off the OnePlus 5 and remove the SIM card tray.
Remove two screws close to USB Type-C port with a T1 screwdriver.

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 opening 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 the 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 four screws securing the USB Type-C port and headphone jack.

The USB Type-C port and headphone jack module are clearly different from the Oneplus 3T.

The upper left corner is the three metal contacts of the power switch. The middle black cable is the NFC module.

Oneplus 5 is still using the classic three-stage design. The upper is the motherboard, the middle is the battery, the lower is the loudspeaker module.

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.

Lift up and disconnect the bottom board cable from the motherboard.

As there is no double-sided adhesive, we can easily remove the rear camera.

Front camera: Sony IMX371, 16 MP, f/2.0
Rear camera: Sony IMX398 16 MP, f/1.7 wide-angle camera, Sony IMX350 20 MP, f/2.6, 1.6x optical zoom camera

The microphone is fixed on the fuselage with glue and can be easily removed.

Remove eight screws securing the loudspeaker module.

Remove the loudspeaker module.

The bottom board is very thin, and it is fixed on the fuselage with glue, it is not easy to remove it.

Uncover the adhesive tape on both sides, and then pull the green tape to remove the battery.

You can see two double-sided adhesives under the 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 used the 5V, 4A DASH fast charge.

The battery cells come from ATL.

As the metal shield is directly welded to the motherboard, so we can not access the chips on the motherboard.

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 the metal plate, and its camera connector is easy to go loose.
