As a very personal mobile phone brand，iQOO has always been unique in the design of the phone itself。 As early as the original iQOO model，The designer matched it with the leading AG glass process in the same period，Creatively realizes translucent brightly colored bright light track LED strips。And on the digital flagships of the subsequent generations，iQOO uses plain leather again、lithography stripes、Photochromic and other special processes and materials，Gives the model a unique and individual look。

such a spirit，at iQOO 9 Pro will naturally not be absent。Recently I got iQOO ahead of schedule 9 The track version of the Pro，It uses the rare aramid fiber material on mobile phones as the back cover。So why did iQOO choose aramid fiber as the back cover material?，What are the advantages of this material?

In order to bring the aramid fiber material to the mobile phone，What efforts has iQOO made?

After getting iQOO 9 The first moments of the Pro Track Edition，You can feel the touch in your hand that is different from the glass back cover。 The ultra-fine aramid fiber material feels delicate enough，but retains the texture。And the deep black is matched with the iconic panoramic porthole of the iQOO 9 series，In a low-key, people can feel the powerful strength contained in the fuselage。On the intractable details of the middle frame connection，iQOO 9 The Pro track version also performs very well，The transition is very smooth，Difficult to feel the gap。In general，iQOO 9 The feel of the Pro track version has reached the top level in the current flagship。

For friends who don't know much about the material of aramid fiber，Here I will do a little science first。Aramid fiber (particularly para-aramid fiber) is a new type of high-tech synthetic fiber developed by DuPont in the United States，aka Kevlar。Aramid fibers have low density、high strength、good toughness、High temperature resistance and other characteristics，Its strength is 5 times that of steel of the same quality，but only one-fifth the density of steel，widely used in military、Racing and other fields。

For example, F1 racing cars use aramid fibers as body materials，Further weight loss while maintaining body strength，Take advantage of better speed in races。At the same time, by virtue of insulating flame retardant properties，Aramid fiber is used in battery case、Battery box partitions and on firewalls，It also greatly improves the safety of the battery box。

Aramid fiber materials have been widely used in the field of digital products since the past 5 years。 under the same thickness and weight，Aramid fiber has more advantages than glass、Plain leather and other materials are lighter and thinner;The impact resistance of aramid fiber is 4.8 times and 9 times higher than that of plain leather and glass, respectively，It has a good protective effect on the battery and the whole machine;Aramid fiber versus carbon fiber and metal，There is no interference phenomenon for the mobile phone signal mask。For the pursuit of thin and light mobile phones，Aramid fibers are undoubtedly an excellent choice for making shells。

And for iQOO，Aramid fiber in aerospace、Outstanding performance in cutting-edge fields such as racing，完美契合了其”SPEEDART”（速度美學）的設計語言。therefore，Apply aramid fiber, a material with strong performance, to mobile phones，It has always been one of the directions that iQOO designers strive to explore.。

certainly，For aramid fibers，It's not easy to use it on mobile。Aramid fiber as a flexible material，Its 3D-formed robustness and fire-resistant coating issues，hindering its popularity on mobile phones。Through technological breakthroughs，iQOO 9 The Pro Track Edition brings a new 3D back cover made of aramid fiber with DuPont Kevlar fiber。

In order to create such a mobile phone back cover，First of all, it is necessary to select ultra-fine 600D aramid fiber for precision weaving texture，Through the delicate surface touch，Satisfy excellent product refinement and finesse。The aramid fiber material is then pre-impregnated with a special thermosetting resin with good fire resistance，Lay 3 layers of aramid fiber material after hot pressing，Then through the vacuum high temperature vulcanization process，Shape 3D arc shape。finally，歷經”7塗7烤2磨”共十六道複雜工序，Get a tablet that weighs only 12.34g、3D back cover made of aramid fiber material that is thin enough to be beautiful and strong enough。

Due to the high strength of the aramid fiber material、Toughness and other characteristics，Ordinary knives cannot cut it，Therefore, iQOO designers processed the edge of the 3D back cover made of aramid fiber by laser cutting.。For problems such as burrs on the edge of the back cover caused by laser cutting，iQOO設計師以”微包邊”工藝進行進一步的處理——採用極少量的PC樹脂包住切割成型后的芳綸纖維材質3D后蓋邊緣，Completely eliminates tiny, nearly invisible burrs，And through gradient spraying, the back cover and the middle frame are more beautifully integrated into one，Spray a layer of matte UV paint on the back cover，Further improve the hydrophobic performance of the back cover to resist hand sweat、Improve durability。

Great Appearance and Powerful Performance

For iQOO 9 Pro's excellent overall performance，We have previously reviewed in detail，Interested friends can click《iQOO 9 Pro review：驍龍8旗艦手機的”全能標杆”》View details。 Here, let me briefly talk about iQOO 9 Features of Pro。

iQOO 9 Pro搭載了全新一代驍龍8移動平臺，It adopts 4nm process technology，20% improvement in peak performance compared to the previous generation mobile platform，30% reduction in power consumption。 memory，Its enhanced LPDDR5 memory，With memory expansion, it can achieve 8GB+4GB、12The effect of GB+4GB storage，The final running score exceeded 1.03 million points。

Not only that，iQOO 9 The Pro is also equipped with the well-received independent display chip Pro，Supports two modes: boost frame rate and high frame low power consumption。 The state-of-the-art hardware configuration enables it to achieve a good result of 57.3fps under the full HD setting of Genshin Impact。

iQOO as the all-round flagship 9 The Pro is also the top configuration on the imaging hardware，Not even inferior to some video 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，Area up to 1/1.57 inch，Unit picture element 1.0μm，After performing 4-in-1 primitives，The size of a single element reaches 2.0μm。Such hardware configuration makes iQOO 9 The imaging prowess of the Pro is best-in-class among current flagship phones，And super wide angle、wide angle、The telephoto three-camera combination can also meet the needs of users in many scenarios from landscape to portrait.。

battery life，iQOO 9 Pro is equipped with 120W ultra-fast flash charge + 50W wireless flash charge，It also supports up to 10W wireless reverse charging，Built-in 4700mAh large battery。In the 5-hour heavy battery life test，iQOO 9 The final charge of the Pro is 43%，For a high-performance flagship，This performance is still satisfactory。

while charging，In the case of power consumption to shutdown，iQOO 9 The Pro takes a total of 21 minutes to fully charge the equivalent 4700mAh battery，5Charges up to 34% in minutes，10Charged to 58% in minutes。 From the line chart，iQOO 9 The charging efficiency of the Pro is very high at all stages，Even in the second half, it still maintains a good level。

The UI design of OriginOS Ocean has been upgraded again，Not only brings us a more beautiful interface design，And it has also been greatly updated in terms of practicality。First of all, OriginOS Ocean adopts a new architecture system on the lock screen interface，In the lock screen interface, users can customize the frequently used functions in the lock screen，And you can set your favorite color，Not only convenient and fast，And the beauty is also greatly increased。A new folder system can hold atomic components and programs of different sizes，Users can also customize the size、color，Users can better control their desktop。 On the most basic fluency of mobile phones，OriginOS Ocean slims down through memory、memory fusion、Atomic motion engine and other functions optimize and tune the bottom layer of the system，Effectively improve the overall fluency of use。

iQOO 9 The use of aramid fiber material on the Pro track version，It is undoubtedly another useful exploration of iQOO in product design。By combining the aramid fiber material widely used in cutting-edge fields with the iQOO with strong performance 9 Pro combined，iQOO once again sets a unique benchmark in the mobile phone market。And for those who are eager to express their individuality on the phone，iQOO 9 The aramid fiber back cover used in the Pro track version can also be made of glass、Another excellent choice for materials such as ceramics。
