For the Double Eleven sale in China, the Realme V3 5G is selling for 999 yuan, about US$150. It's a decent phone with a 6.5-inch screen, three rear cameras, and a 5,000 mAh battery. The Mediatek Dimensity 720 is similar to the popular Qualcomm 765 in Antutu testing. It should be fine for most practical purposes, although the main camera has only 13 megapixels.
I have raised my 2020 yearend estimate to 230-250 million 5G subs because of the low phone prices and strong sales of the iPhone 5G. Apple is actually selling well in China despite the politics. As those prices move West, I predict 2021 5G sales will explode.
Xiaomi, Vivo, Oppo, and Huawei all have models under US$270 at regular prices. Samsung, Sony, OnePlus, and Meizu are avoiding the price war, staying mostly at $500-600 and above. Apple is over $750.
