A fully detailed specification sheet of the OnePlus 3 surfaced at TENAA recently and confirms that the OnePlus 3 won’t have NFC. We did mention it will come with NFC support which was surprisingly missing on the OnePlus 2, but it seems OnePlus still doesn’t want to bring it back. And seeing that the version of the OnePlus listed is the 6GB/64GB model, we can assume that it’s not going to be on even the 128GB version.
Other specifications confirmed include a 5.5’’ FHD AMOLED screen, a Snapdragon 820 processor clocked at 2.2GHz, Adreno 530 GPU, dual nano SIM slots, a 3.5mm earphone jack which should be good news for those who don’t like the new USB type-C audio jacks in some recent flagships; and a 3000mAh battery.
The phone will support all networks, run Android 6.0 Marshmallow, and weigh 158g. [source]
