Xiaomi mobile phone uses Qualcomm chip. Every time you sell a Xiaomi mobile phone, it is equivalent to using Qualcomm's patent fee once, and you need to pay Qualcomm a fee. If the official sales volume of Xiaomi is 1. 1.87 billion, then the patent fee is 3.6 billion yuan.
In communication-related industries, any mobile phone manufacturer can't escape the fact of paying patent fees, so it is necessary for Xiaomi to pay patent fees to Qualcomm.
