Not that the OnePlus Nord was such an incredibly expensive phone, but if it is still too much for your budget then it has also the N100 and N10 5G. Two cheaper models with IPS screens, Snapdragon processor and a fingerprint scanner on the back.
Cheapest of the pair is the OnePlus Nord N100. With a starting price of 199 euros it costs half that of a OnePlus Nord. You get a 6.52 inch screen in return, 13MP camera, a Snapdragon 460 with 4GB of RAM and 64GB of storage. The battery is still on the big side with 5000 mAh and it is support quick charge of just 13 Watt.
OnePlus N10 5G
The OnePlus Nord N10 5G sits between the N100 and the Nord in terms of price, even if it doesn't make much difference. With a starting price of 349 euros you get an even bigger 6.49 inch screen with 90 Hz refresh rate, 64MP camera + ultra wide angle camera with 119° lens + macro and monochrome, a Snapdragon 690 with 6 GB of RAM and 128 GB of storage. The latter is also expandable, something you couldn't do with the Nord. The battery of 4300 mAh on the generous side and it supports 30 Watt fast charging (Warp Charge 30T).
Biggest difference with the Nord are the screen technology (IPS instead of AMOLED) and the location of the fingerprint scanner. The Nord has an in-display fingerprint reader while the N10 and N100 have one on the back of the device. However, the cheaper Nord models also have advantages. For example, they have stereo speakers and their batteries are larger. OnePlus hopes to have the new Nords in stores from November 10.
