The cost of mobile phones adds extra points

The cost of a mobile phone is mainly divided into several parts: hardware (motherboard) software (program) structure (casing, etc.)

The cost of each machine is different,

Let me talk about it from the hardware point of view: the motherboard includes chips, which are divided into different platforms. TI PHILIPS SKYWORKS Motorcycle has its own platform called Fiskar. The chip includes a baseband and a radio frequency part. The baseband is a CPU (DBB) FLASH and an ABB. These are used regardless of parallel imports. The price of things monopolized by European and American companies is about 15-20 US dollars. Some of them require a co-processor and cost 10 US dollars. A few dollars, INTEL or Zoran. Generally speaking, the cost of mainstream mobile phone chips is around US$20. RF chips, including IF and PA, cost about US$5.

Then other small chips such as CODEC charging modules and resistors and capacitors vibrators cost more than 20 US dollars. The motherboard costs over 50 US dollars, and smart phones are more expensive.

The main job of the software is MMI (MAN MACHINE INTERFACE), which is the phone book and touch screen you can see. The cost of these things from large manufacturers is 5-10 US dollars. The driver is the bottom layer, which is provided by the chip manufacturer. Just change the code.

Structure: The larger the manufacturer, the more expensive the casing is. For example, for V3, the casing costs tens of dollars. The L7 casing is cheap, with the whole set of casing costing more than 20 dollars.

In addition, there are research and development expenses, which cost tens of millions in the early stage, and are shared equally with each mobile phone. The production cost is about 10 US dollars per mobile phone, and the total cost of the finished mobile phone is 90-100 US dollars. It is the cost of a mainstream mobile phone. The cost of L7 is not that high, about 70-80 US dollars.

At the earliest, the cost of V998 has dropped to US$30, so the larger the volume of the product, the lower the cost.
