Last October, OPPO officially released the Reno Ace, which comes with a 65W SuperVOOC GaN charger. It is reported that this is also the first time that the third-generation semiconductor material – GaN (gallium nitride) has been applied to a phone's original fast charger, making OPPO the world's first manufacturer to introduce gallium nitride technology into phone chargers. This also announced that gallium nitride technology has officially entered the original phone charger market. According to online information, the reason OPPO's 65W SuperVOOC technology does not use traditional silicon power devices is that as charging power increases, the size becomes larger, which brings inconvenience to users in terms of usage and portability. However, by using gallium nitride power devices, not only can the size of the transformer be reduced by increasing the switching frequency, but also, thanks to the high efficiency of gallium nitride, the heat sink can be reduced or omitted, thereby making the size of high-power chargers more compact. On February 13, Xiaomi launched its star product, the 65W GaN charger, at a new product launch event, sparking market attention on GaN. According to Xiaomi, the Xiaomi GaN charger has 65W power but is only half the size of a traditional charger with the same power, offering advantages such as compactness, high efficiency, and low heat generation. The "hero" that gives Xiaomi's charger so many advantages is the gallium nitride material.The term "GaN" has been successively "favored" by phone manufacturers, so what exactly is GaN? Here, I will briefly introduce it to everyone. Gallium nitride is a typical representative of third-generation semiconductor materials (i.e., compound semiconductors). Germanium, second-generation semiconductor materials like gallium arsenide and indium phosphide, and third-generation semiconductor materials (including gallium nitride, silicon carbide, zinc oxide, etc.) can withstand higher voltages, are suitable for higher frequencies, can achieve higher power density, and have characteristics such as high temperature resistance, corrosion resistance, radiation resistance, and large bandgap width. They have broad application prospects in fields such as high-frequency, high-power power electronics, and microwave radio frequency. Gallium nitride technology is maturing, and its application in the USB PD fast charging field has become very common. GaN technology allows chargers to have increasingly higher power while becoming smaller in size, ensuring product portability. It is understood that at CES2020 this year, 30 manufacturers, including Anker, launched 66 GaN fast charging products. It is worth noting that compared to previous years, the number of GaN fast charger factories at this CES exhibition has increased significantly, which also reflects from the side that GaN fast charging technology is maturing and being recognized by the majority of manufacturers. The industry is developing at a rapid pace, and manufacturers who have taken the lead in deploying GaN fast charging products have gained market recognition and seized the first-mover advantage. At the same time, with the iteration and innovation of technology, product costs have dropped considerably. This time, Xiaomi's launch of the GaN charger is expected to further stimulate market demand. In the future, if Apple also adopts this technology, the penetration rate of GaN chargers will accelerate. Currently, many manufacturers' GaN fast charging products have seen their shipment prices drop to the level of traditional silicon power device products, which is highly attractive to brand owners. I believe that in the future, gallium nitride will shine brightly in the fast charging industry and ultimately replace traditional silicon power devices. Keywords: Editor: What Fish? Reference address: June 17, 2022 – Xiaomi's new phone POCO C40 was officially released. As a popular model for the mass market, the POCO C40 has a simple appearance and comprehensive configuration.

Large screen with high frame rate and excellent camera capabilities The POCO C40 uses the largest screen in POCO brand history: a 6.71-inch screen with a waterdrop notch design and a resolution of 1650*720 HD+. The JR510 supports video at 1080P+ resolution with a frame rate of up to 60fps, so it can easily drive this large screen. In terms of photography, the POCO C40 features a dual rear camera setup with a 13MP main sensor and a 2MP depth sensor, and a 5MP front camera. With such impressive specifications and the JR510's deep optimization, the POCO C40 delivers a great user experience. New POCO C40 launched, powered by Leadcore Technology JR510 chip platform / San Yan Finance News, June 14: According to Tianyancha App, on June 14, Xiaomi Automobile Technology Co., Ltd. published a patent for "Vehicle control method, device, storage medium, electronic device, and vehicle." The abstract shows that the method includes: determining a target detection area based on the current position of the target vehicle, obtaining historical driving trajectories of one or more sample vehicles in the area and intersection information of pending intersections, thereby controlling the target vehicle's movement. This method can determine accurate intersection information and control the target vehicle without high-precision onboard maps or when maps are inaccurate. The vehicle control patent can accurately determine intersections / Today, Xiaomi POCO announced that the POCO F4 is equipped with Qualcomm Snapdragon 870 flagship processor, which the company claims is the best-optimized Snapdragon 8-series chip. The Snapdragon 870 is considered Qualcomm's annual divine chip, built on TSMC's 7nm process, with a CPU that includes one A77 (3.2GHz) super core, three A77 (2.42GHz) large cores, and four A55 (1.8GHz) small cores. Other specifications are consistent with the Snapdragon 865 Plus, and the 5G baseband is also the Snapdragon X55 5G. In addition to the Snapdragon 870, the Xiaomi POCO F4 also features a center-punched hole-punch display with a 120Hz refresh rate and FHD+ resolution. More importantly, the Xiaomi POCO F4 supports OIS optical image stabilization, which uses the phone's gyroscope and accelerometer to detect shake at high speed, transmits the signal to the OIS processing end to calculate the required compensation displacement, and then sends the data in real time to the micro If you want to know how popular a certain phone brand is, the simplest way is to directly look at its product sales and market share. In the past two years, Xiaomi has been unstoppable, repeatedly creating sales miracles. Its global smartphone market share and total shipments have surpassed Apple, second only to Samsung! This is indeed a remarkable achievement. But observant people will notice a fact: although Apple's total phone sales are lower than Xiaomi's, its prices are higher! If we compare high-end phones priced above 5000 yuan, iPhone sales, profit margins, and total transaction amounts can all beat Xiaomi. Why is that? The A-series chip has stronger performance! The hardware configuration emphasizes balance, and the average level is very stable. Xiaomi phones offer high cost-performance, which is well known to everyone. Among all domestic Android phones in the same price range, Xiaomi phones often have better performance. However, no matter what processor chip this Xiaomi phone is equipped with, it cannot be compared to Apple's iPhone. Apple's A-series processor On June 6, Southern+ reporters learned that Xiaomi has recently adjusted its organizational structure, merging the Xiaomi Product Department and Redmi Product Department to form the Mobile Phone Product Department, with Ling Xiaobing serving as the general manager of the Mobile Phone Product Department. It is reported that the newly established Mobile Phone Product Department will have three sub-departments: Xiaomi, Redmi, and Pad. Shi Shasha will serve as the head of the Xiaomi Product Department; Guo Ruimin will serve as the head of the Pad Product Department; and Ling Xiaobing will continue to serve as the head of the Redmi Product Department. Previously, when Ling Xiaobing served as the head of Redmi products, he only reported to Lu Weibing, Senior Vice President of Xiaomi Group and General Manager of the Redmi brand. After this promotion to General Manager of the Mobile Phone Product Department, he will report to both Lu Weibing and Zeng Xuezhong, President of Xiaomi Mobile Phone Division and General Manager of Xiaomi Mobile Phone Product Department. Some industry insiders say that this adjustment is also related to the departure of Chang Cheng in January this year. On one hand, it fills the vacancy left by Chang Cheng's departure; on the other hand, it is also conducive to strengthening the coordination between Xiaomi and Redmi phones. On June 8, Xiaomi and Leica reached a global imaging strategic cooperation, which sparked global attention. Tech media GIGA said that Xiaomi has already demonstrated the level of Chinese companies in the field of phone cameras with the Xiaomi 11 Ultra, and the Xiaomi 12 Ultra may become the new king of cameras.
