First, remove the back cover with your fingernails. You can start from the charging port at the bottom, and then slowly extend to other areas.
Remove the nano-SIM card tray.
Remove all screws securing the middle frame. A screw in the lower left corner is covered with a warranty sticker. If you damage it, you will void your warranty.
Once the middle frame is removed, you should be able to access the internal parts, including the battery, camera, and motherboard. There is a layer of graphene thermal coating on the back cover, which serves to conduct the heat generated by the phone to the back cover.
There is a speaker module at the bottom of the back cover, which is secured to the bottom cover with foam adhesive.
Disconnect the battery connector from the motherboard. You can remove the battery.
The OnePlus 2 comes with a 3300mAh Li-Polymer battery.
The OnePlus 2 employs a single piece of magnesium-aluminum alloy for its frame, giving the phone very good hardness.
Remove the screws securing the small circuit board at the bottom, then use tweezers to pry it up and remove it.
The small circuit board at the bottom connects to the motherboard via a flexible circuit board, which integrates a Type-C port.
The OnePlus 2 features an OV13860 rear camera sensor and an OV5648 front camera sensor.
The main camera has added an OIS function and also joined the two ISP chips for processing image operations.

The chips on the motherboard are all covered with metal shields, and the metal shield of the processor is also coated with thermal grease.
