Powered off the OnePlus 5 and removed the SIM card tray.
Use a T1 screwdriver to remove the two screws near the USB Type-C port.

I tried using a suction cup to remove the back cover, but was unsuccessful.
I insert a crowbar between the back cover and the body and slide it along the display edge to remove the back cover from the body.
Remove the back cover

After opening the back cover, you cannot remove it in this step because a cable is still connected to the motherboard.
Remove the screw securing the metal plate, which is used to secure the battery connector and the USB Type-C cable.
Disconnect the battery connector first, and then disconnect the USB Type-C cable.

The OnePlus 5 features an all-metal unibody back cover and employs large-area nano-injection molding antenna technology to ensure excellent signal coverage.
We can see that the USB Type-C port and headphone jack are secured on the back cover, and there are many metal contacts on the back cover.

The USB Type-C port and headphone jack module are noticeably different from those of the OnePlus 3T.

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

The OnePlus 5 still features the classic three-stage design. The upper part is the motherboard, the middle part is the battery, and the lower part 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 motherboard are not covered with graphite stickers, unlike many smartphones, which use graphite stickers to cover the motherboard and battery.

We can easily remove the rear camera because there is no double-sided adhesive.

The sub-board is very thin and glued to the body, making it difficult to remove.

The OnePlus 5 features a 3300mAh Li-Polymer battery with the part number BLP637. It is worth mentioning that the OnePlus 5 did not upgrade the fast charge capabilities; it still comes with a 20W charger.

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

OnePlus 5 internal parts

According to the teardown process of the OnePlus 5, it can be seen that the internal structure of this smartphone adopts a systematic sealing design, including sealed treatment at the USB-C port. The back cover of the phone also uses foam for sealing. Other internal parts have also adopted the sealing design. Among all the smartphones I have disassembled before, only products from manufacturers such as Apple, Samsung, OPPO, and vivo have adopted such strict sealing designs, with reinforced corners on the back cover. Even so, there are still some weak points in the internal design of the phone: its connectors are not secured with metal plates, and the camera connectors are prone to loosening.

  1. Hi, good details on the phone’s construction. Could you tell me how good the phone is and how it compares to the OnePlus 3T?

    Thanks

  2. There is a problem with my OnePlus 5. The call volume is so low. Even after I tried to upgrade the software, it’s still the same. Using volume apps does not help. It could be a hardware issue, but I’m not sure.
    Is there any way to change the call speaker, or do you have any idea how to solve the issue? I never found a way to download the previous version on their website.
