Looking back at the development history of the back cover of the mobile phone, from plastic to metal to glass, in fact, the back cover of different materials has shortcomings, the plastic texture is poor, the metal weight is large, and the glass is not resistant to falling. Even if there is now the so-called Corning Victus glass, as long as there are small sand particles on the road surface, the mobile phone can still be broken when it falls on the ground, and the impact resistance of the glass back cover is poor, and it is difficult to effectively protect the fuselage battery motherboard from being impacted.
So is there a material that takes into account the texture, weight and fall resistance of the back cover? The iQOO 9 Pro Track Edition gives the answer: aramid fiber (also known as Kevlar). Aramid fiber is a high-tech material, its strength is 5 times that of steel wire, and the weight is only 1/5 of steel wire, and aramid fiber has a special texture, which can bring a very good texture.
Thanks to the properties of aramid fibers, it is even widely used in the military field, making body armor and helmets. Subsequently, aramid fibers have also begun to be promoted in the high-end field of civil use, and have been applied to aerospace, racing, high-strength ropes and other markets. Nowadays, this high-end material is the first to be quoted by iQOO on the back cover of the mobile phone, according to the official parameters, iQOO 9 Pro Track Edition compared to traditional glass, impact resistance increased by 9 times!
In contrast, the legendary version with the glass back cover weighs 210 grams, while the track version with Kevlar material weighs only about 203 grams, so the aramid fiber material can not only greatly improve the impact resistance, but also can effectively reduce the weight of the mobile phone, I think the future aramid fiber should be the new development direction of the mobile phone back cover.
In order to achieve a better feel, iQOO uses 16 complex processes, 24800 test hands, millions of hardware-level investment, and finally applies the perfect 3D arc to the iQOO 9 Pro track version, so this should be the most expensive mobile phone back cover process ever for iQOO!
In terms of texture, the aramid fiber material is relatively smoother, with a very delicate and rich texture, and basically will not be contaminated with fingerprints, the black mobile phone back cover with a deep oversized cloud lens module, iQOO 9 Pro track version gives people the feeling of being low-key, calm, cold, very handsome.
In terms of specific hardware configuration, the machine uses the Snapdragon 8Gen1 processor, with a 4700mAh battery and 120W fast charging, as well as 50W wireless reverse charging. The use of cascading VC liquid cooling heat dissipation, with independent display chip, you can get the ultimate game experience. In terms of screen, the machine uses a top-level screen of Samsung 2K E5 LTPO2.0. In addition, the highly acclaimed ultrasonic fingerprint has also been preserved. In terms of imaging system, the 50 million GN5 micro-gimbal main camera, the 50 million ultra-wide angle lens and the 16 million pixel 2.5x optical zoom lens are also flagship.
In today's mobile phone has become more and more homogeneous, iQOO 9 Pro's attempt at a new material for the back cover is still very encouraging. The machine will go on sale on March 1st, if you are interested in this new material, you can pay attention to it!
