Recently, "core shortage" has become a hot topic. Not only mobile phones, but also automobiles, computers, scientific research and other industries are facing the dilemma of core shortage. In addition, the United States is very good at creating technology monopolies, so even if it can obtain chips, it will have to pay a high price. In the mobile phone industry, even companies as strong as Apple are facing a situation of being "stuck".
As we all know, mobile phone baseband chips are basically monopolized by Qualcomm. Apple uses Qualcomm’s baseband chips. For every mobile phone sold by Apple, it has to pay Qualcomm a patent fee of about 50 yuan. In order to save this huge expense, Apple began to develop its own 5G baseband chips a few years ago, but recently there was news that the research and development failed. In fact, this is not because Apple’s technology research and development capabilities are insufficient, but because it cannot avoid Qualcomm’s two patents. Therefore, iPhones in the next few years will still use Qualcomm's baseband chips.
Not only baseband chips, but also mobile phone power management chips have been monopolized by the American company TI Texas Instruments for many years. After the monopoly, they were sold to domestic mobile phone manufacturers at high prices and made a lot of money. Good news came. Xiaomi, the domestic mobile phone giant, officially counterattacked. It officially announced that Xiaomi has developed a self-developed Power Management Chip, The Paper. This chip has achieved millisecond-level power management capabilities and refined management of the charging and discharging of mobile phones. Every 1mAh of power is wasted. With the support of this chip, the battery life of the Xiaomi Mi 12S series has improved by 15% compared to the Xiaomi Mi 12! Moreover, the fast charging chip Pengpai P1 + the power management chip Pengpai G1 allow Xiaomi to achieve comprehensive self-research of the battery management system!
From ThePaper S1, to ThePaper C1, the first self-developed ISP chip, and then to ThePaper P1 and ThePaper G1, Xiaomi’s huge R&D investment is constantly being implemented. Lei Jun said that Xiaomi will invest 100 billion yuan in technology research and development in the next five years. He believes that in the next five years, the monopoly of foreign technology giants will be broken one by one by domestic mobile phone manufacturers. By then, they will want to make money from the Chinese by charging huge patent fees. , that is absolutely impossible.
In addition to the self-developed chip, Xiaomi 12S Pro has a very balanced configuration in all aspects. The Snapdragon 8+ processor, which uses TSMC’s 4nm process, has a running score of over 1.1 million! Officials say that the overall power consumption has dropped by 30%, and the Snapdragon 8+ is finally not hot this time. As for the screen, it uses a 6.73-inch second-generation LTPO 2K screen, and adds microprism technology to bring higher brightness and lower power consumption. If nothing else, this should be the best screen among domestic mobile phones.
In addition, Xiaomi has also developed its own new FBO storage technology. After 4 years of use, the speed of flash memory reading and writing has hardly declined. In addition, the Xiaomi Mi 12S Ultra will use a one-inch super outsole sensor IMX989, and the Xiaomi Mi 12S Pro main camera will be an outsole IMX707, with three 5000W main cameras, all supported by Leica optical lenses. This will be the ceiling for mobile phone photography!
