The birth of Coolpad brand is the product of Coolpad transformation, and the brand-new brand image is closer to young consumers. Coolpad 1 dual released some time ago, with its more fashionable appearance, advanced functions, excellent performance and ultra-low price, well interprets the latest brand image of Coolpad. The Cool Changer S 1 in this evaluation is based on the brand concept of Cool and extends the product line. Positioning at a higher end, meeting people who have higher requirements for hardware performance and music quality.
Cool Changer S 1 not only uses the top chip Qualcomm Snapdragon 82 1, but also has outstanding performance. At the same time, Coolpad also cooperates with Harman Kardon to provide music technical support for mobile phones, so that users can get a better listening experience whether they are playing outside or wearing headphones. In addition, as a flagship mobile phone, its performance in taking photos and battery life is naturally not bad. Let's make an objective evaluation of it through parameter information first.

From the parameter table, the multimedia performance of Cool Changer S 1 is its greatest strength, which includes the joint action of hardware and software. Snapdragon 82 1 chip and Universiade memory ensure sufficient performance support. In terms of software, Harman Kardon made his debut in sound quality, and LeTV system also enriched multimedia resources, providing users with comprehensive support from content to hardware as a whole, and accurately grasping the pain points of consumers complaining about the poor sound quality of mobile phones.
It should be noted that Cool Changer S 1 cancels the traditional 3.5mm headphone jack, and has built-in AKG N 18 custom headphones and a Type-C adapter. In other words, if you don't use accessories, you can't listen to songs with headphones and recharge them. Fortunately, it supports QC 3.0 fast charging, and can output CDLA full-frequency digital lossless audio through Type-C interface to obtain better sound quality.
"Slim body+excellent grip.
The industrial design of Coolpad mobile phone is always inseparable from angular and tough lines in our impression. This design style is obviously biased towards the aesthetics of mature men and does not conform to the aesthetics of the current fashion trend. After the strategic transformation, the design style in this area has obviously faded, and the Coolpad brand was jointly created by LeTV and Coolpad. Therefore, the design of Cool Switch S 1 also introduced the elements of LeTV.
Cool Changer S 1 uses a 5.5-inch LCD screen with a resolution level of 1080P. Not only the edge of the screen has a 2.5D curved surface transition, but also the display effect is very delicate, and no graininess can be seen at all under normal viewing distance. Generally speaking, the design of Cool Changer S 1 follows the principle of complete symmetry. The receiver integrates a front speaker, which can sound simultaneously with the speaker at the bottom of the fuselage to create a stereo effect. Sensors on both sides of the receiver are symmetrical with cameras of the same size, and the combination of light sensor and distance sensor saves an unnecessary opening, which makes the front look more concise. In addition, for the sake of visual unity, the reminder light and the three physical buttons at the bottom are also designed to be hidden.
The borderless design of ID can create infinite visual effect when the screen of mobile phone is closed, but the obvious black edge after the screen is lit greatly affects the perception. Cool change S 1 does not adopt ID borderless design, and the border control is also excellent. However, it should be noted that there is no plastic buffer between the screen and the metal frame of the mobile phone, so the risk of screen breakage when the mobile phone falls is high. It is recommended to wear protective cover or buy screen damage insurance.
There are only two openings at the top of Cool Changers S1,one is an infrared sensor, through which the mobile phone can realize the remote control function. The other is a noise-reducing microphone. The traditional 3.5mm headphone jack is cancelled, and the headphones can only be connected to the mobile phone through the Type-C jack at the bottom of the fuselage. In addition, from this photo, we can see that the middle frame of Cool Changers S1has been cut by CNC, and there is an arc transition on the back of the fuselage, which feels very good, and there will be no cutting feeling in your hand.
At the bottom of the fuselage, the cooler S 1 adopts a symmetrical design, and the left and right sides are still openings for speakers and microphones. In addition, the advantages of USB Type C interface should be well understood. It supports faster data transmission speed and larger charging current, and is the quasi-successor of conventional Micro USB interface. It is worth mentioning that after canceling the 3.5mm headphone jack, Coolpad Changer S 1 fully supports the CDLA standard (all-digital lossless audio). In addition, in order to facilitate compatibility with the user's existing audio equipment, the mobile phone comes with a Type C to 3.5mm audio interface adapter.
The body of Cool Changer S 1 is polished by sand blasting, which retains the original texture of the metal body and feels good. The camera part is still convex, and the fingerprint identification button is also designed in a mirror. The LOGO at the bottom is more interesting, emphasizing cool brands. The following is LeEco inside, coolpad, Harman/Kardon logo. Among them, the brand of Coolpad has been greatly diluted, which in turn highlights Coolpad and the main brand Harman/Kardon.
Generally speaking, the design of Cool Change S 1 is not unique, except that there is no ID on the front and no border, and there is no wiredrawing design on the back, so it is basically impossible to jump out. Nevertheless, these two changes are indeed urgently needed by many consumers.
"EUI 5.8 based on Android 6.0.
Cool Changer S 1 has the software blessing of LeTV, which is worthy of a leap in user experience. EUI created by LeTV has always been committed to creating a "borderless" ecosystem. After more than a year of iteration, EUI is as perfect as MIUI, Flyme and other deep customization systems, and has some unique selling points. Cool Changer S 1 is equipped with EUI version 5.8 based on Android 6.0. 1 In this version, Coolpad specially customized a set of icons for it, and with Harman Kardon wallpaper, the overall interface became more colorful and fashionable.
In addition to the default theme specially customized by Coolpad, EUI itself has two additional themes to choose from: gorgeous and elegant. The system theme also supports customization, and you can freely choose fonts. Although the degree of customization is not as high as that of domestic old Android UI such as MIUI, it ensures the integration of system themes to some extent.
In terms of the basic functions of the system, EUI 5.8 further enriches the functions and practicability of the system. There are also many functions such as global search, WeChat trumpet, yellow page dialing and so on, which are basically the standard of domestic Android UI. Slightly different, in the global search, EUI integrated more resources, such as searching for "Joker Xue", then related materials, videos, music, apps and so on. Will appear in the search results.
It is worth mentioning that for young users, chasing drama, chasing the ball and idolizing are all essential. Calendars in EUI 5.8 allow users to track the information they want. For example, if you pay attention to Shawn Yue, if his TV dramas and new singles are released recently, they will appear in the user's calendar as a reminder. Of course, you can also pay attention to your favorite team, even LOL players. Because LeTV has many star resources, the mobile phone equipped with EUI has become an out-and-out idol artifact. In EUI 5.8, you can see the star homepage, ringtone, expression and photo wallpaper.
The biggest feature of EUI is the integration of LeTV's rich video content services. Happy Desktop and Live Desktop can be accurately personalized pushed according to users' search behavior and historical data. Dynamic desktop is the essence of EUI. When the live desktop is turned on, the mobile phone will automatically switch to landscape mode, and users can watch live satellite TV, starry sky, movies, TV series and variety shows. The screen defaults to nine videos, which can realize three live broadcasts at the same time.
EUI's main interface actually integrates many applications, such as LeTV headlines, LeTV videos and LeTV sports. Every interface is the entrance to LeTV's ecology. You can enter other related applications through users' personal interests without frequently switching apps within the LeTV ecosystem. What you want is what you get. This is also the concrete embodiment of LeTV's ecological opposition and breaking the APP island.

On the basis of Android 6.0. 1, the cool changer S 1 system interface EUI 5.8 deeply optimizes the power consumption and performance, and the support of Snapdragon 82 1 platform further ensures the fluency of the system. After several days of experience, EUI 5.8 is satisfactory in stability and fluency. But in the experience, LeTV and its rich resources and content are even more impressive.
"Ann Bunny running test.
The Cool Switch S 1 in this evaluation is the version of Qualcomm Snapdragon 82 1 processor, with 4GB of running memory and 64GB of body storage space. I believe many friends are wondering whether Snapdragon 82 1 is obviously different from Xiaolong 820 and whether it is worth upgrading. Let's compare these two CPUs intuitively through a parameter table.

In fact, even from the product naming, we can see that Snapdragon 82 1 is only a slightly upgraded version of Xiaolong 820. From the above parameter table, we can also intuitively see that Snapdragon 82 1 mainly improves the main frequency of CPU and GPU. According to official data, CPU performance is improved by 10%, GPU performance is improved by 5%, and power consumption is reduced by 5%. On the whole, Snapdragon 82 1 has a certain performance improvement compared with Xiaolong 820, but the improvement range is limited. As far as user experience is concerned, the difference should not be too big.
Judging from Ann Bunny's running score, the score of Cool Changer S 1 is just in the first echelon. Although there is a slight gap compared with Le Pro 3 and Xiaomi 5S Plus, there is not much difference from the actual experience. However, the running score of Snapdragon 82 1 mobile phone is about 1W compared with Xiaolong 820, and there is no obvious difference in actual experience. So you don't have to worry about choosing Xiaolong 820 or Snapdragon 82 1, because there is no obvious performance gap between them.
"Camera Imaging Quality Test"
As for the camera, Cool Changer S 1 adopted Sony IMX298, which is widely adopted by this year's flagship. This year, all major flagship mobile phones have applied this CMOS. In terms of hardware, Le Pro3 adopts16 megapixel camera, F2.0 aperture, PDAF phase focusing, DTI pixel isolation technology, and is equipped with dual color temperature LED fill light. From the configuration point of view, Cool Changer S 1 does have flagship camera hardware.
In terms of camera function, Cool Changer S 1 has four modes: slow motion, video, photo and panorama. The camera interface is intuitive, which can not only adjust the basic parameters such as exposure value, white balance and ISO, but also adjust the contrast, sharpness and saturation in real time, which is very convenient. Let's take a look at the real shooting level of Cool Changer S 1 through the proofs. (Click on the picture to view the original picture)
Because IMX298 CMOS has been installed in many flagship mobile phones, it is quite mature in debugging. You basically don't have to worry about the camera level of this mobile phone. The biggest highlight of Cool Changer S 1 is that the background blur ability is excellent and the white balance performance is relatively stable. The problem is that the color scheme is slightly dull and not too eye-catching.
"Cool Changer S 1 External Audition"
It should be emphasized that as a "changer", Cool Changer S 1 has made great efforts in audio technology. It adopts the design of double speakers and double integrated sound cavities, and the receiver at the top can also produce sound, creating a stereo effect. In addition, Cool Changer S 1 equipped the two speakers with independent intelligent amplifiers, which greatly increased the volume, enabled the speakers to achieve low noise and high dynamic output at the highest loudness, reduced signal distortion, enhanced low-frequency performance, clear and rich range, fresh timbre and stronger three-dimensional sense.
In addition, the cooperation with Harman Kardon has enabled Cool Changer S 1 to gain the support of three technologies, namely Clari-Fi.
Lossy sound source recovery algorithm
Lossy sound source recovery algorithm and LiveStage
Sound field broadening algorithm of earphone. Among them, the former can restore the compression details of MP3, wmv and other audio formats to the greatest extent through the algorithm, and effectively improve the sound quality; Clarifi
The stereoscopic effect can also be realized by software algorithms, which allows users to have a better immersive experience when watching movies or playing games. The latter is to use the algorithm to correct the position of the earphone sound field, improve the problem that the earphone sound field is located in the center of the head, widen the sound field forward and upward, and will not cause the feeling of "beating the head". Because the video was shot without professional radio equipment, the sound quality was lost and the stereo effect was not obvious. However, despite this, I am still very shocked by the release ability of Cool Changer S 1. Not only the voice is loud, but also the bass is rich and the treble is not harsh, the voice and accompaniment are clear, and the real number is not easy.
"Evaluation summary
"
Harman Kardon's tuning, AKG N 18 customized headphones, LeTV's ecological content and top-level hardware parameters, it is obvious that Coolpad is meeting consumers again with great sincerity. And whether it is the selling point of the product or the marketing strategy, Coolpad has grasped the key points. Judging from the current mobile phone market, young people have the strongest demand and purchasing power for mobile phones. Cool Changer S 1 has completely solved the problem of poor sound quality of cost-effective mobile phones, which can be described as grasping the pain points of consumers. Bian Xiao was lucky to get this mobile phone before the press conference. After a few days of use, I found that the change of Cool Machine S 1 completely changed my brand impression of Cool. Snapdragon 82 1+4070mAh battery keeps pace with performance and battery life. Exquisite and practical EUI and excellent imaging level make me feel very comfortable and comfortable during use. On this basis, the audio performance is a bonus for Cool Changer S 1, and I can hardly find its shortcomings. If you insist on finding fault in an egg, the design can be bolder.
