As a very personalized mobile phone brand, iQOO has always been unique in the design of the mobile phone itself. As early as the original iQOO model, the designers equipped it with the leading AG glass process of the same period, creatively realizing the translucent bright light rail LED strip with bright colors. In the subsequent digital flagships, iQOO has adopted special processes and materials such as plain leather, lithography stripes, and photochromic discoloration, giving the model a unique personality appearance.
iQOO 9 Pro Track Edition
Such a spirit will naturally not be absent on the iQOO 9 Pro. Recently, I got the track version of the iQOO 9 Pro in advance, which uses the rare aramid fiber material on the phone as the back cover. So why did iQOO choose aramid fiber as the back cover material, and what advantages does this material have? Let me take you on a look.
01 In order to bring aramid fiber material to mobile phones, what efforts has iQOO made?
The first moment you get the iQOO 9 Pro Track Edition, you can feel a different touch in your hand than the glass back cover. The ultra-fine aramid fiber material is delicate enough to feel, but retains the texture. The deep black with the iconic panoramic porthole of the iQOO 9 series can make people feel the powerful strength contained in the fuselage in the low profile. In the difficult details of the middle frame connection, the iQOO 9 Pro Track Edition also performed very well, the transition was very smooth, and it was difficult to feel the gap of the connection. Overall, the iQOO 9 Pro Track Edition has reached the top level of the current flagship.
For friends who do not know much about the material of aramid fiber, here I will first do a small science popularization. Aramid fiber (specifically referring to para-aramid fiber) is a new type of high-tech synthetic fiber developed by DuPont in the United States, also known as Kevlar. Aramid fiber has the characteristics of low density, high strength, good toughness, high temperature resistance, etc., and its strength is 5 times that of the same quality steel, but the density is only one-fifth of that of steel, and it is widely used in military, racing and other fields.

For example, F1 racing cars use aramid fibers as body materials to further reduce weight while maintaining body strength and exert better speed advantages in races. At the same time, with the characteristics of insulation and flame retardancy, aramid fiber is used in battery boxes, battery compartment separators and firewalls, which also greatly improves the safety of battery boxes.
Aramid fiber materials are widely used in the field of digital products from the past 5 years. Under the same thickness and weight, aramid fiber has a lighter and thinner feel than glass, plain leather and other materials; the impact resistance of aramid fiber is 4.8 times and 9 times higher than that of plain leather and glass, respectively, which plays a good protective role for batteries and the whole machine; aramid fiber is relative to carbon fiber and metal, and there is no interference with mobile phone signal shielding. For mobile phones that pursue thin and light, aramid fiber is undoubtedly an excellent choice for making shells.
For iQOO, the outstanding performance of aramid fibers in cutting-edge fields such as aerospace and racing is a perfect fit for its "SPEEDART" (speed aesthetics) design language. Therefore, the application of aramid fiber, a material with strong performance, to mobile phones has always been one of the directions that iQOO designers strive to explore.
Of course, for aramid fiber, it is not easy to apply it to mobile phones. As a flexible material, aramid fiber has hindered its popularity on mobile phones due to its robustness after 3D molding and the problem of fireproof coating. Through a breakthrough in craftsmanship, the iQOO 9 Pro Track Edition brings a new 3D back cover of aramid fiber material containing DuPont Kevlar fiber.
In order to create such a mobile phone back cover, it is first necessary to select ultra-fine 600D aramid fiber precision weave texture, through the delicate surface touch, to meet the excellent product refinement and fineness. The aramid fiber material is then pre-impregnated with a special thermosetting resin with good fire resistance, and the 3 layers of aramid fiber material are superimposed and superimposed, and then the 3D curved surface shape is shaped by vacuum high temperature vulcanization process. In the end, after a total of 16 complex processes of "7 coatings, 7 baking and 2 grinding", a piece of aramid fiber material with a weight of only 12.34g, which is thin and beautiful enough and strong enough, was obtained.
The iQOO 9 Pro Track Edition excels at the mid-frame articulation
Due to the high strength and toughness of the aramid fiber material, ordinary tools cannot cut it, so iQOO designers process the 3D back cover edge of the aramid fiber material in a laser cutting manner. In response to problems such as burrs at the edge of the back cover caused by laser cutting, iQOO designers used the "micro-hemming" process to further process - using a very small amount of PC resin to wrap the edge of the 3D back cover of the aramid fiber material after cutting and molding, completely eliminating the almost invisible fine burrs, and through gradient spraying, the back cover and the middle frame were more beautifully integrated, and a layer of matte UV paint was sprayed on the back cover to further improve the hydrophobic performance of the back cover to resist hand sweat and improve durability.
02 Excellent appearance with powerful performance
For the excellent comprehensive performance of iQOO 9 Pro, we have previously reviewed in detail, interested friends can click "iQOO 9 Pro Review: Snapdragon 8 Flagship Mobile Phone "All-round Benchmark"" to view the details. Here I would like to briefly talk to you about the features of the iQOO 9 Pro.
The iQOO 9 Pro is equipped with a new generation of Snapdragon 8 mobile platform, which adopts a 4nm process process, which is 20% higher than the peak performance of the previous generation mobile platform and reduces power consumption by 30%. In terms of memory, its enhanced version of LPDDR5 memory, with memory expansion, can achieve the effect of 8GB+4GB, 12GB+4GB storage, and the final score exceeds 1.03 million points. Not only that, the iQOO 9 Pro is also equipped with the well-received standalone display chip Pro, which supports two modes: improved frame rate and high frame low power consumption. The top hardware configuration gives it a good score of 57.3fps in the case of the full high quality setting of "Original God".

As an all-round flagship, the iQOO 9 Pro is also the top configuration in the imaging hardware, and even not lost to some imaging flagship models. It uses a 50-megapixel main camera + 50-megapixel fisheye ultra-wide angle lens + 16-megapixel double telephoto lens. On the main camera, iQOO 9 debuted its ISOCELL GN5 sensor jointly developed with Samsung, with an area of 1/1.57 inch, unit pixels 1.0μm, and after a pixel 4-in-1, the size of a single pixel reached 2.0μm. Such a hardware configuration makes the imaging strength of iQOO 9 Pro reach the first-class level in the current flagship mobile phone, and the combination of ultra-wide angle, wide angle and telephoto can also meet the needs of users in many use scenarios from scenery to portraits.
