Now various manufacturers are launching their own Internet e-commerce brands. A common phenomenon of such smart phones is low price and high allocation. IUNI U2 is the first model of IUNI brand. Since its release, it has given users a little fresh and tasteful feeling of youth. When U2 Push went on the market, it was equipped with zero pre-installed IUNI OS, Qualcomm 800 and high-end configuration of metal body, but the price was only 1799 yuan. This time, the slogan of IUNI U3 was changed to "I love shows", so U3 is targeted at young users aged 20-30. These users are more willing to pursue flagship configuration and DIY personalization, and the price has been controlled at 2000 yuan.

Let's first review the main parameters of IUNI U3 and the 5.5-inch Sharp second-generation 2K resolution screen. The PPI reached 538, and the screen ratio was as high as 77%. It adopts Qualcomm Snapdragon 80 1 chip with the main frequency of 2.3GHz, is equipped with a storage combination of 3 GB RAM and 32 GB ROM, and has a built-in 3000mAh trapezoidal battery, which supports FDD/TDD dual 4G, five-mode and fifteen-frequency dual-card dual standby technology. IUNI U3 deserves to be the highest-priced mobile phone of 2000 yuan (before publication).
Frank, general manager of IUNI, said at the press conference that the overall design of IUNI U3 is to cater to this 2K screen. Indeed, when we first got started, whether it was a gorgeous screen, 2.5D glass and curved back, it felt very good and the integrity of the fuselage was very high. So our evaluation today is all about this screen.
The front of the IUNI U3 fuselage is equipped with a 5.5-inch 2K screen with a resolution of 2560x 1440 pixels, and the pixel per inch is as high as 534ppi. But at first glance, it is not how excellent the screen is, but the proportion of screens under the screen is very high. In today's era of serious homogenization of smartphones, if you want to be different, you must have a bright spot. When many friends see the new mobile phone, they will say, "Oh, the horse racing frame of your mobile phone is so ugly." On the contrary, the narrow border is gradually considered beautiful by mass users.
The narrow border of IUNI U3 is 3.2 1mm, which makes the screen ratio of this machine reach 77%. Looking at the past, the screen occupies a large part of the fuselage. This design not only increases the aesthetics of the fuselage, but also reduces the volume of the fuselage. I still remember that before the press conference, the size of the new 5.5-inch screen body exposed by IUNI was very close to that of the 5-inch screen body. The body size of IUNI U3 is 145x74.9x 10.3mm, while the size of Sony Z 1 with a 5-inch screen is 144x74x8.5mm, with a height difference of 1mm and a width difference of 0.9mm..
From the above picture, we can clearly see OPPO Find7, IUNI U3 and Xiaomi 4. IUNI U3 and OPPO Find7 also use a 5.5-inch 2K screen, but the body size is much smaller.
The advantage of this design is that it can increase the beautiful picture of the product; Secondly, it can reduce the size of the mobile phone and make it easier for users to operate the large-screen mobile phone. Of course, this is by no means the design adopted by the IUNI family. For example, LG G3, which was listed not long ago, also has such a design. In the future, Sony Z3, Meizu MX4 and other machines will adopt this design.
IUNI U3 wants a high screen ratio, and it is not enough to occupy the border. IUNI U3 embeds the antenna in the metal case, saving the space of the antenna module, so the lower frame of the fuselage is only 10mm, which is also the narrowest mobile phone at present. Of course, this design should not change the keys into virtual keys. Before, some friends complained that virtual buttons would take up screen space and were unfamiliar. Among them, virtual buttons are more flexible, and users can hide or change the content they browse.
Therefore, it is not enough to use the third generation Corning gorilla glass for a mobile phone designed around the screen. IUNI U3 also has two major improvements on the screen glass. First of all, the difference of 2.5D radian glass is that the edge position of the whole glass is smooth, and the smooth edge has more anti-collision ability, higher safety and more durability than the right-angle edge. Of course, as mentioned in the release, the 2.5D curved glass makes the fuselage look more like a water drop, and there is a surface with a span of 5mm around it, which will be smoother when touched by hand. Secondly, the surface of IUNI U3 screen is coated with a layer of CANOOPTRON AF, which can make the touch of the screen very smooth.
There are not too many designs on the top and bottom of IUNI U3. The top is a 3.5mm headphone jack and the bottom is a Micro USB data jack. This design is also adopted by most mobile phones, because in most scenes of daily life, separating the data cable from the earphone can effectively avoid the trouble of winding the two wires together. In addition, the Micro USB interface also supports OTG function, and can be connected with a USB flash drive to expand storage space or novel playing modes such as mouse and keyboard.
We all remember that IUNI U2 adopts an all-metal body design, but this time it is replaced by a plastic back cover. So where did the metal go? In fact, IUNI U3 adopts a fuselage front frame design similar to Xiaomi 4, but the difference is that IUNI U3 adopts a more advanced aviation-grade aluminum-magnesium alloy design, which is also used in Meizu MX4.
This kind of aviation aluminum alloy is made after 8 NC machining and 23 working procedures. Frank said that this process takes 72 minutes to process on the machine tool. In addition, IUNI announced that the front frame is 24.8 grams, and the overall weight of the fuselage is 179 grams. The overall weight is medium. Many friends will definitely ask, is this a little too small? In fact, in addition to looking good, the most important role of metal frames of many mobile phone manufacturers is to strengthen the fuselage. In order not to affect the use of the curved fuselage at the back, the frame design is not large, but U3 also has bright edges cut by laser.
There are two main reasons why IUNI U3 doesn't use metal fuselage. First, as a quality young man, he must have something unique, so this time IUNI U3 has a customized back cover in addition to the regular black, white and green. Secondly, in order to solve the shortcoming that IUNI U2 can't "desktop mode".
The back shell of IUNI U3 fuselage is made of frosted plastic, which can effectively avoid fingerprints and has a good overall texture. This time, IUNI U3 adopted a durable strong paint effect, which enhanced the color durability of the mobile phone paint. The black version we got today is Mo Chi Black, and official website has two colors to choose from: Sunshine White and Wind Lotus Green. It is worth mentioning that IUNI U3 adopts the same color body design. As the name implies, the color of the back cover and panel is uniform, and there will be no panda machine.
The most important thing is that IUNI U3 specially found the personalized back shell drawn by beautiful painters from eight fine arts institutes, and also launched the personalized Logo back shell of Microsoft Xiao Bing series. In the future, we can submit customized information in official website to customize our unique personalized back cover. This is an attitude of pursuing taste, but I prefer a textured metal body.
The body of IUNI U3 is also a curved body, but the curvature is much smoother than that of the previous generation, and there will be no phenomenon that the desktop can't be put down and the screen can't shake. The brand IUNI focuses on young activities, so many of them are students or young users under the age of 25, so users often touch their mobile phones on the desktop. The improvement of IUNI U3 curved fuselage can perfectly realize "desktop mode" and keep the good feel of curved fuselage.
During the experience of the press conference, the author found that IUNI U3 had a disadvantage. That's a detachable back cover, but there is no gap around the fuselage to open the back cover. I can only break it through the data interface. This will not only damage the fuselage but also scratch the user's nails. However, in the official version of the packaging, the author found a lid opener, which we can use to open the back cover of the fuselage, but the seamless design only needs to start from the data interface.
There is a13 megapixel camera supporting optical image stabilization on the top of IUNI U3, which used to look domineering. However, the author found that U3 adopts a curved fuselage design, and the camera glass point is just the top of the fuselage curvature. It is inevitable that there will be wear and tear for a long time, but after several days of use, the author did not find any wear and tear in the experience machine. 13 megapixel F2.0 optical anti-shake main lens with large aperture and 4 megapixel Ultra pixel front lens, please refer to the camera section.
As for the smartphone system, there are only three platforms: Android, WP8 and benchmark iOS. Android platform is widely used, and its OS is also varied. The most representative ones must be MIUI of Xiaomi, Flyme of Meizu, TouchWiz of Samsung, Sense of HTC and IUNI OS of the protagonist. With the rapid development of smart phones, many commonly used softwares are pre-installed in OS. These softwares are convenient for users who need them, but they are inevitably redundant for users who don't, so IUNI OS adopts zero pre-installation.
IUNI U3 will be equipped with the latest Android 4.4.4 operating system, and will continue to focus on simplicity and refreshing style. On the basis of this fresh and flat style, IUNI has also increased its cooperation with other APP manufacturers, such as the deep optimization of Baidu Music and pea pods, which has enriched the network resources of the machine. At the same time, IUNI OS also strengthened the system-level firewall to supervise the software functions; And for large-screen operation, IUNI OS also enhances the experience of gesture operation.
On February 17 this year, IUNI OS was officially released, with the product concept of "born in purity, don't forget your active mind". On February165438+1October 20th last year, at the beginning of brand establishment, we also shouted "Take Xiaomi against Xiaomi". Anti-Xiaomi does not directly confront Xiaomi, but refers to the opposite of Xiaomi's gameplay in some specific aspects on the basis of Xiaomi mode. By the date of U3 release, IUNI OS has adapted to 1 1 versions, and accumulated 1202 problems, which shows that IUNI OS is still successful.
He Xiaojun, general manager of IUNI Technology, believes that "for the IUNI brand, IUNI OS is a more important value support than mobile phone hardware." Because the positioning of IUNI is not a simple hardware manufacturer, but a service provider of mobile Internet life. IUNI OS can be summed up in a few words: concise, smooth, stable and pure.
IUNI OS only keeps the native functional modules of the system, and zero pre-installation is not equal to zero service. IUNI OS aims to connect the services with APP service providers to the underlying functions of the system, and form a service delivery that is more in line with the user's situation than a simple APP application. At present, IUNI OS has reached such cooperation with sogou, LBE, Douban and other partners. So users who need a lot of apps need to download them themselves.
At the press conference, IUNI didn't emphasize the camera too much, but IUNI U3 also adopted a13 megapixel large aperture optical anti-shake main lens and a 4 megapixel Ultra pixel front lens. The F2.0 main camera is the mainstream level for the current flagship mobile phone, and everyone is using it. However, it is interesting to talk about the 4 megapixel Ultra pixel front lens first, because it uses the same technology as the HTC mobile phone, but don't forget that HTC ONE is used in the back.
On the camera, we only found the choice of greener filter, and IUNI OS, which has always done "subtraction", did not let users have too many settings in camera settings, so the fool's approach is still very commendable. In addition, IUNI gives us independent focus and sidelight when the scene is in focus, which is really practical. Well, before it's too late, let's take a sample.

As can be seen from the proofs, the performance of IUNI U3' s13 megapixel optical anti-shake lens is still very good. We can see that the edges of the oil and cream on Danish bread are very clear. In addition, the performance of the 4 megapixel Ultra pixel front lens is also excellent. From the comparison of indoor toy proofs, we can clearly see that the image of Ultra pixel front lens is brighter, but it is slightly inferior to13 million pixels in detail.
IUNI U3 gives users a perfect answer sheet, both on the front and back. In addition, it is also a pleasure for us to use the 2K screen to review the proofs. This also reminds me of Frank, general manager of IUNI, who said that all our designs revolve around this 2K screen. This can also make the user's mood greatly increase during use.
Just now, we mentioned that IUNI U3 uses a 5.5-inch Sharp second-generation 2K resolution screen, with a PPI of 538. Compared with the previous generation of 2K screen, it has higher refresh rate, more power saving and wider color gamut. In fact, the working principle of the new 2K screen is to reduce the working pressure of the GPU. For example, we can chat on WeChat while browsing the web. At this time, the screen can only handle the dynamic side. Such graphics processing technology can reduce the pressure of GPU, ease the operation of processor and save power. OPPO Find7 is also a seed player, with a 5.5-inch 2K screen. We will retake the test pictures to see how IUNI U3 and OPPO Find 7 perform.

By remaking the test chart, we can see that the screen saturation of IUNI U3 is better than that of OPPO Find7, but the screen brightness is obviously not as good as that of OPPO Find 7. In the test chart, we can see that the white color of OPPO Find 7 can be bright, and other colors have obvious whitening phenomenon. The advantage of high brightness can be better displayed under strong light, and IUNI U3 feels like looking in the mirror under strong light. But in any case, it is an excellent 2K screen. As for whether the 2K screen consumes power, we have also tested it on VIVO phones before. Experiments show that the power consumption of 2K screen is not bad compared with that of 1080P screen, and this time IUNI U3 uses the second generation 2K screen, which also saves electricity.
As mentioned earlier, IUNI U3 is basically equipped with the most advanced hardware at present. Comprise a 2.5GHz high-pass Snapdragon 80 1 processor and 3GB of running memory.
2K resolution screen, etc. How is the performance? To evaluate this part of the article, let's pass the software test.
Ann Bunny is a common running software.
UNI U3 uses Qualcomm 80 1 processing chip, and its running score on Ann Bunny is 39 104. Close to 40 thousand's good results also let it join the flagship model family. Many friends in the back will ask me.
Why is there a gap between UNI U3 and the above processor equipped with Qualcomm 80 1 on Ann Bunny? In fact, U3 University
Equipped with the latest MSM8974AA processor.
By comparing these pictures, we can see that I

There are differences in main frequency, GPU main frequency, ISP main frequency, eMMC version, DSDA support and memory IF. Simply put, a generation is different from ordinary people in all aspects.
The ability of MSM8974AC is slightly poor.
But in daily life, we don't realize the difference.
Next, let's briefly explain the performance improvement of Snapdragon 80 1 processor.
Next, let's test it with other running software. Vellamo is a well-known browser testing software. The main aspects of the test include JavaScript, HTML5 and other performances, which are very important for mobile phones.
Browser and other experiences have a great influence, and also test the computing power of the processor, which reflects the comprehensive ability of software and hardware to some extent. As can be seen from Vellamo's HTML5 test project, in the HTML5 test,
IUNI U3

NenaMark2 is a hardware acceleration benchmark program for Android devices, which tests the graphics capabilities of mobile phones by demonstrating a real-time rendered picture, including reflections, dynamic shadows, surface parameters, complex light patterns and so on. Through the test results, it can be seen that the improvement of CPU architecture and main frequency also brings about the improvement of GPU performance, that is
UNI U3
The score on Nenamark2 is 60. 1.9fps.
4G network is also a major feature of IUNI U3, which supports both TD-LTE and FDD-LTE standard 4G networks and backward compatible WCDMA and GSM networks. U3 is also a dual-card dual-standby mobile phone, which supports FDD/TDD dual 4G and can realize five modes and fifteen frequencies.
4G+2G dual card simultaneous standby technology. So we don't have to bring two mobile phones when we work or travel.
At the end of the article, I want to talk to you about the battery life and purchase of IUNI U3. Because a high-end smart phone, if the battery life is unsuccessful and the price is expensive, then it is not within the consideration of our ordinary users. Because what we want is a good and cheap mobile phone, after all, no one's money is blown by the wind.
In terms of battery, IUNI U3 also adopts the current high-end LG trapezoidal battery. The trapezoidal battery can make full use of the radian space on the back of the mobile phone and increase the battery capacity of 10% without increasing the thickness of the mobile phone. Seeing here, we can see that IUNI really surrounds this screen anywhere in the fuselage.
IUNI adopts a detachable battery design and is equipped with a 3000mAh lithium battery. Although it is not detachable, it can still meet the daily needs of users. In order to better simulate the actual usage, the author tracked and recorded the battery usage of moderate IUNI U3. Including making phone calls, watching videos with WIFI, playing local videos, playing local MP3 audio, playing games, testing the charging effect of photos, etc. PS: This endurance test is also the endurance standard test of IT 168 mobile phone channel. You can refer to other models for comparison.
After the author's actual simulation test, the battery power is 34%. This test course does not include the 8-hour standby endurance test. There is no problem in using IUNI U3 normally for one day. I also tested IUNI U3 because most of my friends have to move the power supply to charge when they go out.
Charge from 20% to 100% needed 1 hour 05 minutes.
The official price of IUNI is 2000 yuan, which is in line with the statement that the flagship of 2K screen only sells 2K. In terms of purchase, as a member of JDPhone, the aircraft will be sold in JD.COM and IUNI official website. However, it should be noted that the aircraft will start booking the excellent tour on September 10, and there will be a large number of launches afterwards. At the same time, in order to avoid snapping up, a strict queuing reservation system will be introduced. Click to view details.
Although IUNI U3 only took 4 days, we think this machine is still good, mainly in two aspects. The first is the field of vision. Sharp's second-generation 2K resolution screen has a PPI of 538, and the screen ratio is as high as 77%. Most of the front of the fuselage is a screen and it is a high-definition screen with 2K screen. Even users who don't understand mobile phones have an unconscious feeling, which is in line with IUNI U3' s love of "show". Secondly, the feel, CANOOPTRON AF coating and curved body all gave me a good experience. Of course, it is not all advantages, but also regrets. For example, the author thinks that the customized back shell is creative, but for me, I hope to have a metal back cover. Regarding the purchase, IUNI U3 can be said to be the mobile phone with the highest price of 2,000 yuan at present (the date of publication), and Xiaomi, Yijia, Glory and other machines need refueling. A cost-effective selling logic also needs to be optimized. At the same time, in order to avoid snapping up, a strict queuing reservation system will be introduced. This logic is similar to the way hammer mobile phones are sold. Will the user buy it or not? See you in September 10.
