The top version of Xiaomi note adopts Qualcomm Snapdragon 8 10 processor 2. 1, 8-core 64-bit architecture, and the single-core performance of the built-in Cortex-A57 is up to 90% higher than that of the previous generation.
There are four graphite fins built into the fuselage. Based on Xiaomi Note, the frame structure of the fuselage is optimized to make the heat dissipation of the whole machine more uniform, and a heat conduction process is developed for CPU to improve the heat conduction efficiency. In this process, Xiaomi has applied for five patents of heat conduction technology. Through the powerful adjustment of the processor and the improvement of heat dissipation technology, the top version has finally become a Snapdragon 8 10 mobile phone with mass production capacity, and the mobile phone has also reached a higher performance level. Ann Bunny's performance test reached 63,424 points, the flagship performance.
Xiaomi and Sharp /JDI deeply develop customized screens, and all raw materials such as backlight, film, glass and liquid crystal are well-known suppliers, reaching higher screen standards. In order to make this screen have a better picture effect, it is also equipped with advanced sunshine screen technology, negative liquid crystal technology and high color saturation technology, which makes the top version of the 5.7-inch screen condense advanced screen technology and perform better.
The top version of Xiaomi note is equipped with Sony IMX2/KOOC-0/4/KOOC-0/30,000 pixels+optical image stabilization, and Qualcomm/KOOC-0/4 bit image processor, and adopts dark light image quality enhancement technology.
Xiaomi's patented technology flattens the optical anti-shake camera, adopts the well-known Sony IMX2 14 photosensitive element, and adds Qualcomm 14bit image processor, which can support 55 million pixel image processing. Through dynamic range adjustment and dark light image quality enhancement technology, the photo has less noise and better image quality.
On the slim body of the top version, the battery capacity of the top version still increased by 3%. At the same time, in order to further improve the charging efficiency, on the basis of the original fast charging and fast charging 2.0, two charging chips are equipped, and the parallel charging technology is constructed, which makes the charging efficiency higher and the heating more uniform during charging. 1 hour can charge 70%, saving more charging time.
The top version adopts customized version ESS SABRE90 18C2M, which is equivalent to ES9018c2m in performance and smaller in chip size. Adding a two-stage regulated power supply system can provide better power output, stronger transient response and louder sound when the signal changes dramatically. 8 PPS audio capacitor is added to further improve the purity of sound quality. The mobile phone is equipped with such a professional HiFi music system, and the top version also makes every link reach its peak, which is amazing.
Xiaomi Note Top Edition covers mobile, China Unicom and telecom networks, and supports LTE Cat 9 network technology, which is one of the advanced 4G network technologies. The maximum downlink speed of TDD is as high as 330Mbps, and that of FDD is as high as 450Mbps.
