Does Xiaomi have any core patents?

1, charging technology Xiaomi mobile phone's 100 watt charging technology is widely circulated in the industry. Previously, many manufacturers found that in addition to battery capacity, the charging speed of mobile phones is another influencing factor. To this end, Xiaomi began to invest in Xiaomi charging laboratory. After launching100W wired fast charging, it also launched wireless fast charging, which has a number of patents for mobile phone fast charging technology. Xiaomi mobile phone equipped with fast charging technology was also evaluated as a super fast charging mobile phone by CCTV at that time. 2. Privacy protection technology Privacy protection is a hot topic in recent two years. With the popularity of big data algorithms, the recommendation of personalized content requires users to authorize personal information, and the privacy protection involved becomes particularly important. Xiaomi's MIUI is a mobile phone system that introduced privacy protection earlier. Since MIUI 12 introduced privacy protection functions such as flare, blocking net and hiding mask, it has successively updated functions such as intelligent clipping privacy protection, file sandbox mechanism, web browsing privacy protection and location information privacy protection, and is in a leading position in the field of mobile phone privacy protection. 3. Updating storage technology As we all know, after the mobile phone is used to a certain extent, the memory is constantly read and written, resulting in different degrees of garbage accumulation, resulting in the situation that the mobile phone is stuck. In order to solve this problem, Xiaomi launched an independent research and development technology called FBO Huanxin Storage. As the name implies, this technology is specially developed for memory, which can support automatic detection and sorting of data fragments stored in mobile phones. According to the laboratory data, a mobile phone with a reading speed of 1900MB/s will drop to 400MB/s after four years of simulated use, which greatly reduces the performance of the mobile phone. After applying FBO refresh storage technology, the reading speed of mobile phone can be restored to the level of 1900MB/s, which effectively avoids the performance degradation caused by memory garbage accumulation in long-term use of mobile phone. 4. Chip technology Chip is one of the core keys of mobile phone. Mobile phone manufacturers have already laid out the chip field, and Xiaomi is no exception. Previously, Xiaomi has entered the chip field through production and investment, becoming the second mobile phone manufacturer in China with the ability to develop self-developed mobile phone chips. Although it seems difficult to develop mobile phone chips independently, it needs to compete for technology, design ability and return on investment, but mobile phone chips, as the brain of mobile phones, have a high priority. For this reason, Xiaomi has laid out mobile phone chips for many years, and has released and mass-produced four chips, involving mobile phone soc, mobile phone images, fast charging chips, battery management and other directions, and completed many explorations from mobile phone processors to mobile phone auxiliary chips.
