Evaluation of Xiaomi 13, the three-year answer to high-end strategy.

Xiaomi's high-end strategy began with Xiaomi 10 series in 2020. With continuous exploration and change, the performance of Xiaomi's high-end products is getting better and better. As the answer to Xiaomi's three-year exploration of high-end strategy, Xiaomi 13 series ushered in a comprehensive upgrade of processor, memory and flash memory for the first time. At the same time, it has a golden size and excellent texture and feel.

The design of Xiaomi 13 follows three key words: light, energy and order. This time, the design style of 13 is also very different from that of Pro products. The use of straight screen allows more users to have more purchase options.

Xiaomi 13 is equipped with a 6.36-inch full screen, and the content is full of the front of the fuselage. The screen border is 1.6 1mm wide, and the screen ratio reaches 93.3%. Xiaomi also optimized the internal structure of the screen a lot, and then combined with the unique frame design, finally achieved such an immersive look and feel.

The frame of Xiaomi 13 is made of light aluminum alloy, which makes the highlight effect softer and more shiny. The vertical frame design with ultra-narrow black border highlights the visual impact of large screen display.

The back of the whole machine adopts 3D glass technology, and the part connected with the vertical frame has a smooth transition. The camera follows the design language of 13 series, and integrates three cameras and flash into a concise and coherent square.

The thickness of Xiaomi 13 is only 7.98mm, and the weight is also controlled at 189g, which brings a light and thin feel. The screen of Xiaomi 13 is protected by Corning Gorilla Glass, and the whole machine supports IP68 dustproof and waterproof, which makes it more secure for daily use.

Xiaomi 13 adopts brand-new E6 luminescent material, which greatly improves the luminous efficiency. Under the same brightness, the power consumption is 22% lower than that of Xiaomi 12. Outdoor, the full-screen brightness can reach 1200nit, and the highest peak brightness can excite 1900nit, so that the contents on the screen can be clearly distinguished even in the sun.

We are in an era when HDR content gradually spreads from Hollywood to civilians. HDR can accurately restore the details of the brightest and darkest parts in the picture, which is the most important dimension to improve the realism of the picture besides resolution. Xiaomi 13 supports the display of four Hollywood HDR standards, namely HDR 10, HDR 10+, Dolby Vision and HLG, which can accurately display P3 wide color gamut with brightness exceeding 1000nit.

Xiaomi 13 is equipped with front and rear dual light sensing and ambient color temperature sensing, which supports natural eye protection mode and reduces the proportion of harmful blue light without obviously changing the color temperature. Xiaomi 13 has passed SGS eye protection certification and supports full brightness DC dimming.

As the flagship of a new generation of images, Xiaomi 13 is equipped with all the imaging capabilities of native Leica, bringing a new shooting experience.

Xiaomi 13 rear three lenses, covering the optical zoom range from 0.6 times super wide angle to 3.2 times telephoto, and supporting up to 30 times digital zoom. Each lens has passed Leica optical certification, with high resolution, large aperture and almost imperceptible distortion, which provides a solid foundation for excellent image quality.

The main lens has 7P aspheric mirror design, ALD professional ultra-low anti-reflection coating, brand-new cycloolefin material, and supports HyperOIS super optical image stabilization. The main camera adopts a new redundant Sony IMX800 sensor with an effective pixel of 50MP, which can make use of the additional 3.5% redundant area to get a larger field of view when shooting video.

By default, the main camera adopts 4-in-1 reading mode to generate a photo of 1250 pixels. When dual zoom is needed, the main camera switches to the 50-megapixel readout mode and takes a photo with the center of12.5 million pixels, thus achieving the dual zoom effect without losing the clarity. It also changed Xiaomi 13 from super wide angle to telephoto lens, and realized the smooth relay of focal length transformation of 15-23-46-75.

1980, Leica released the first SUMMILUX 75mm lens, and then equipped Leica ·M4P and Lace M6 with 75mm viewfinder wireframes. Leica's legendary 75mm production line will continue to introduce new models until 2020. The telephoto lens of Xiaomi 13 is designed with an equivalent focal length of 75mm and a large aperture of f2.0, which supports OIS optical image stabilization.

When appreciating portrait photos, the audience will involuntarily focus on the portrait face. In order to avoid facial distortion, it is often necessary to keep the distance between the photographer and the subject above1m. Under such conditions, if you want to take busts and headshots, you must use telephoto lenses.

As a classic focal section of Leica, 75mm has a 32-degree FoV, which just meets this requirement. When you are one meter away from the portrait, you can take a big photo at 75mm, and you can take a bust and bust after stepping back a few steps. Comfortable shooting distance can also avoid the deformation of the face at the four corners of the picture, but it will not cause communication difficulties too far away. Compact composition can effectively avoid messy objects in the picture and make the subject more prominent.

Computational photography, local real-time AI, games, the main functions of these mobile phones all need strong hardware computing power support. Facing the use demand, the core specifications of Xiaomi 13 have also been comprehensively upgraded to better meet all the needs of current users for mobile phone use.

The energy efficiency ratio of the second generation Snapdragon 8 mobile platform has doubled, reaching the best performance since the third generation, which also makes Xiaomi 13 have excellent cooling experience and endurance.

The second-generation Snapdragon 8 mobile platform adopts a brand-new architecture design, adding Cortex-A7 15 core. When performance is most needed, A7 15 and A7 10 will become the mainstay, bringing strong and lasting performance. Based on the new TSMC 4 nm process, the transistor density has also increased by 20%. The performance is improved while the power consumption is reduced, and the energy consumption ratio is the best compared with the last three generations of the Xiaolong 8 series platform.

The comprehensive performance of the second-generation Snapdragon 8 mobile platform CPU is improved by 37% compared with the previous generation, and the peak performance of the brand-new hyper-core Cortex X3 is improved by 17%. Thanks to the new clustering architecture of A7 15+A7 10, the number of large cores not only increased by one, but also the performance was improved by 50%. As the A7 10 architecture is retained, similarly, the small energy-efficient core A5 10 also adds velvet to the 32-bit application, so that the 32-bit app can run in the background with low power consumption, further improving the endurance of the whole machine.

Compared with the first generation Snapdragon 8, the core evasion of the new Adreno GPU is improved by 50%, the graphics performance is improved by 42%, and the power consumption is also reduced. Adreno GPU also provides many new functions from the game console, such as VRS variable coloring rate, hardware-level ray tracing and so on.

The frame rate of the Battle of Genshin Impact Abyss is maintained at 60fps.

Combined with leading hard power and excellent software tuning, Xiaomi 13 is not only an excellent mobile phone in Genshin Impact in the Android camp, but also surpasses iPhone 14 in frame rate and temperature. The brightness will not decrease during the whole game, and the temperature control is also ideal. Even in scenes with heavy loads such as running maps in Sumeru City, the number of frames will not change significantly.

Xiaomi 13 uses a brand-new LPDDR5X memory, with a peak frequency of 8533Mbps and a throughput of Apple M 1. The UFS4.0 flash memory, which is standard in the whole system, can realize 3.5GB/s sequential reading and 2.6 GB/s sequential writing speed. ..

Xiaomi 13 also supports Xiaomi's new self-developed technology FBO ring storage technology. This technology can automatically detect and sort out the memory fragments of mobile phones, effectively avoiding the performance degradation of mobile phones after long-term use. After four years of simulation, the reading and writing speed decreased by nearly 0%. FBO update storage technology is automatically implemented and optimized by the system.

In order to make the performance output of the whole machine more stable, Xiaomi 13 also upgraded Xiaomi's dynamic performance scheduling technology to a more elaborate strategy. Based on the thermodynamic model for the first time, it can predict the temperature rise trend of the mobile phone and optimize the performance release in advance. Xiaomi 13 also designed a huge VC radiator of 4642mm2, which covered almost half of the fuselage area and had excellent heat dissipation performance. Xiaomi 13 performed very well in various overload scenes in real life.

Xiaomi 13 also brings brand-new low-power Wi-Fi and 5G dual-card dual-pass, as well as a series of network services and protocol optimization, which has lower power consumption for both daily use and high-speed throughput.

Xiaomi 13 supports Wi-Fi 6 wireless network, 4QAM and dual WLAN acceleration, and can provide the highest military speed of 3.6Gbps (5 GHz+2.4 GHz). The FastConnect module of Xiaomi 13 was upgraded to 14nm process, and a number of software and strategy optimizations were carried out, which reduced the power consumption of Wi-Fi subsystem by up to 30% under different loads.

The previous mobile phone "dual card dual standby" can keep both SIM cards in the network state and can answer incoming calls. But when one of the cards makes a phone call, the other card will go offline-no internet access, no text messages, no phone calls.

The emergence of "dual-card dual-pass" in the 5G era completely corrected this problem, allowing two SIM cards to be online at the same time. Even if the main cartoon is talking, the secondary card can still surf the Internet, send and receive short messages and even answer the phone at the same time. Users can switch between two calls freely without interference. Xiaomi 13' s dual-card dual-pass supports SA+SA and SA+LTE, which exceeds the band combination of 140 network and ensures good compatibility.

In terms of battery life, Xiaomi 13 brought the latest 4500mAh high-density silicon-oxygen negative electrode battery, which adopted 4.48V electrochemical system and MCP cell packaging technology, and the energy density reached the industry-leading specifications at the same power. Compared with Xiaomi 12, which is also 4500mAh, the battery volume is reduced by 5%. Similarly, Xiaomi's self-developed G 1 battery management chip is built in the battery, and MNP integrated packaging technology is adopted, which brings more accurate power calculation and high security to Xiaomi 13, effectively delaying battery aging.

Xiaomi 13 is equipped with 澎湃 P 1, which is by far the most powerful and complicated multifunctional fast charging chip. It can not only realize the function that originally required two charge pumps, but also support the output current of 16A at the highest.

Based on this capability, Xiaomi 13 supports 67W wired charging, 50W wireless charging and 10W wireless reverse charging. Xiaomi 13 also supports time-domain charging optimization, delaying charging time at night to avoid continuous battery charging.

Xiaomi's self-developed G 1 battery management chip and Xiaomi's P 1 constitute Xiaomi's battery management system, which can further improve the charging and discharging safety, endurance, endurance and accuracy of remaining available time. With the addition of P 1, the estimation accuracy of the remaining available time can be significantly improved through the self-developed battery management algorithm and self-learning model, and the accuracy will be gradually improved with the increase of the user's use time.

The high-end strategy in the past three years has influenced the products of Xiaomi digital series and profoundly changed Xiaomi.
