Hardware used to be very cheap now. Now the so-called good mobile phone is expensive in the added value and brand value, such as IP, that is, the system is good, the service is good, and there are many software, so it is valuable. Its hardware is not contracted by Foxconn, and Apple itself does not have the production capacity. Like Samsung, the system is also doing well, plus the brand value, and then the price is high. Buy a Samsung mobile phone with a price of 3000 yuan. This brand should cost at least 500 yuan. Xiaomi mobile phone is a futures model. When it was released, it was often the top configuration at that time, but it was months or even half a year later when it was listed. By then, these hardware have been reduced in price. So it is cheap, and as a domestic brand, there are not so many tariffs. Xiaomi is actually an Internet company. It sells an internet model (software, system), and the mobile phone is just a carrier. So Xiaomi is also famous for MIUI, there are good and bad here. Real hardware is actually not expensive. So is Redmi. Don't just look at 4 cores or 8 cores. There are many kinds of 4-core or 8-core, and there are also high and low levels, so the prices are naturally different.
