The OnePlus 8 has a 6.55-inch AMOLED display with 2400 x 1080 pixel resolution and a 90Hz refresh rate - not the 120Hz reserved for the OnePlus 8 Pro.

There's a Qualcomm Snapdragon 865 at the heart of the phone with 8GB RAM - it also supports 5G. There's the option of 128 or 256GB storage.

The front camera is 16-megapixels; the triple rear cameras are led by a 48-megapixel main camera.

The front camera is again 16-megapixels, with a rear system that's led 48-megapixel main camera. It's a quad system on the 8 Pro, however, although John Lewis doesn't go into detail about what all those cameras do.
