Traditional manufacturers transform into the Internet, Coolpad Changer S1 review
IT168 mentioned the brand Coolpad in the review. I believe that almost everyone knows about it, ranging from 99% to 99% to just 20% off. Although it is a joke, it is closely related to Coolpad’s many years of channel accumulation. However, as a traditional mobile phone brand that relied on operators, it has been suppressed by many emerging mobile phone manufacturers under the wave of the Internet. Since Liu Jiangfeng took over as CEO of Coolpad, Coolpad's brand image has undergone earth-shaking changes. Through the Cool brand, Coolpad has strengthened its user-centered business philosophy and achieved a true strategic transformation.
The birth of the Cool brand is the product of Coolpad’s transformation process. The new brand image is closer to young consumers. With a more fashionable appearance, advanced functions, excellent performance and ultra-low price, the Cool 1 dual released some time ago is a good interpretation of Coolpad's latest brand image. The Coolpad Changer S1 reviewed this time is based on Cool’s brand concept and is an extension of the product line. Positioning is more high-end to meet the needs of people with higher requirements for hardware performance and music quality.
Coolpad Changer S1 not only uses Qualcomm Snapdragon 821, the top chip, but also has outstanding performance. At the same time, Coolpad has also cooperated with Harman Kardon to provide music technology support for the mobile phone, allowing users to obtain a better listening experience whether it is played externally or worn with headphones. In addition, as a flagship mobile phone, its performance in terms of photography and battery life is naturally not bad. Let’s first make an objective evaluation of it through parameter information.

Judging from the parameter table, the multimedia performance of Coolpad Changer S1 is its biggest strength, which includes the unique functions of hardware and software. The Snapdragon 821 chip and large-scale RAM ensure sufficient performance support and software. In terms of sound quality, Harman Kardon has debugged the sound quality, and the LeTV system has also enriched multimedia resources. Overall, it has provided users with comprehensive support from content to hardware, and accurately captured the pain point of consumers complaining about poor sound quality on mobile phones.
It should be noted that the Coolpad Changer S1 has canceled the traditional 3.5mm headphone jack and has built-in AKG N18 custom headphones and Type-C adapter. In other words, if you do not use accessories, It is impossible to charge while listening to music with headphones, but fortunately it supports QC 3.0 fast charging and can output CDLA full digital lossless audio through the Type-C interface for better sound quality.
"Thin and light machine. Body + excellent grip
The industrial design of Coolpad mobile phones is always inseparable from our impressions of clear edges and corners and tough lines. This design style is obviously biased towards the aesthetics of mature men and is inconsistent with the current fashion trends. After the strategic transformation, this aspect of the design style has been significantly downplayed, and the Cool brand is jointly created by LeTV and Coolpad. Therefore, elements of LeTV are also introduced in the design of Coolpad Changer S1.
The Coolpad Changer S1 uses a 5.5-inch 1080P resolution LCD display. Not only does the edge of the screen have a 2.5D curved surface, but the display effect is very delicate, and there is no graininess at all under normal viewing distances. Overall, the design of Coolpad Changer S1 follows the principle of full symmetry.
The earpiece part integrates a front speaker, which can emit sound at the same time as the speaker on the bottom of the fuselage, creating a stereo effect. The sensors on both sides of the earpiece are symmetrical and the same size as the camera. The light sensor and distance sensor are combined, eliminating an unnecessary opening and making the front look more concise. In addition, for the sake of visual unification, the reminder light and the three physical buttons at the bottom are also designed to be hidden.
The ID’s borderless design can create a visual borderless effect when the phone’s screen is turned off, but the obvious black edges after the screen is turned on greatly affect the look and feel. Coolpad Changer S1 does not adopt an ID borderless design, and the border control is also very good. However, it should be noted that there is no plastic buffer zone between the screen and the metal frame of this phone. The risk of screen breakage is higher when the phone falls. It is recommended to wear a protective case or purchase screen breakage insurance.
There are only two openings on the top of the Coolpad Changer S1. One is an infrared sensor, which allows the phone to function as a remote control. The other one is a noise-canceling microphone. The traditional 3.5mm headphone jack has been cancelled, and the headphones can only be connected to the mobile phone through the Type-C interface at the bottom of the fuselage. In addition, we can also see from this photo that the middle frame of the Coolpad Changer S1 has been CNC cut, and there is an arc transition on the back of the fuselage, which makes it feel very good in the hand and does not feel like it is cutting your hands. .
At the bottom of the fuselage, the Coolpad Changer S1 adopts a symmetrical design, and there are still openings for speakers and microphones on the left and right sides. In addition, everyone should be very familiar with the advantages of the USB Type C interface. It supports faster data transmission speeds and larger charging current, and is the quasi-successor of the conventional Micro USB interface. It is worth mentioning that after canceling the 3.5mm headphone jack, the Coolpad Changer S1 fully supports the CDLA standard (full digital lossless audio). In addition, in order to facilitate compatibility with users’ existing audio equipment, the phone comes with a Type C to 3.5mm converter. Audio interface adapter.
The body of Coolpad Changer S1 has been polished by sandblasting process, retaining the original texture of the metal body and having a good feel. The camera part is still raised, and the fingerprint recognition button also adopts a mirror design. The LOGO at the bottom is more interesting. The COOL brand is greatly emphasized. Below it are LeEco inside, coolpad and harman/kardon (Harman Kardon logo). Among them, the Coolpad brand has been greatly downplayed, and COOL and Harman/Kardon, which are featured this time, have been highlighted.
Overall, the appearance design of Coolpad Changer S1 cannot be called unique. Except for the absence of ID and border on the front and the lack of brushed metal design on the back, it basically does not stand out. However, these two changes are indeed urgently needed by many consumers.
"EUI 5.8 based on Android 6.0
The Coolpad Changer S1 has software support from LeTV, which can be said to have made a worthy leap in user experience. The EUI created by LeTV has been committed to Create a "borderless" ecosystem. After more than a year of iteration, the EUI has become as complete as deeply customized systems such as MIUI and Flyme, and has some unique selling points of its own. It is based on Android 6.0. 1's EUI 5.8 version, in this version, Coolpad has specially customized a set of icons for it, matching the Harman Kardon wallpaper, the overall interface has become more colorful and fashionable.
In addition to the default theme, which has been specially customized by Coolpad. In addition, EUI itself also has two additional built-in themes, gorgeous and elegant, for you to choose from. The system theme also supports customization, and you can freely choose fonts. Although the degree of customization is not as high as that of old domestic Android UIs such as MIUI, it is certain. To a certain extent, the integration of the system theme is ensured.
In terms of basic system functions, EUI 5.8 further enriches the functions and practicality of the system. Global search, WeChat account, dial-up yellow pages, etc. are basically domestic Android UIs. There are many standard functions in EUI 5.8. The slight difference is that in the global search, EUI integrates more resources. For example, if you search for "Joker Xue", all relevant information, videos, music, APPs, etc. will be included. Appear in search results.
It is worth mentioning that for young users, chasing TV dramas, chasing football, and chasing stars are all essential.
EUI 5.8's calendar allows users to track the information they want. For example, if you follow Shawn Yue, if his movies, TV series, or new singles are released recently, they will appear in the user's calendar as a reminder. Of course, you can also follow your favorite teams or even LOL players. Since LeTV Pictures has many celebrity resources, mobile phones equipped with EUI have become out-and-out star chasing artifacts. In EUI 5.8, you can see celebrity homepages, ringtones, emoticons, and photo wallpapers.
The biggest feature of EUI is the integration of LeTV’s rich video content services. LeJian Desktop and Live Desktop can provide accurate personalized push based on users' search behavior and historical data. Live desktop is the essence of EUI. When Live desktop is turned on, the phone will automatically switch to landscape mode. Users can watch live satellite TV, celebrity channels, movies, TV series, variety shows, etc. on this desktop. The screen defaults to nine-channel video, which can realize simultaneous playback of three-channel live streams.
The main interface of EUI actually integrates many applications, such as LeTV Toutiao, LeJian Video, and LeTV Sports. Each interface is the entrance to the LeTV ecosystem. There is no need to frequently switch APPs within the scope of the LeTV ecosystem, that is, Users can enter other related applications through their personal interests, and what they want is what they get. This is also a concrete manifestation of LeTV’s long-term emphasis on ecological transformation and breaking down APP silos.

EUI 5.8 deeply optimizes power consumption and performance based on Android 6.0.1, and is further guaranteed by the blessing of the Snapdragon 821 platform improve the system's fluency. After several days of experience, EUI 5.8 is satisfactory in terms of stability and fluency. But in the experience, LeTV and its rich resources and content are even more impressive.
"Antutu Benchmark Test
The Coolpad Changer S1 in this review is a Qualcomm Snapdragon 821 processor, 4GB running memory, and 64GB body storage space version. I believe Many friends are wondering whether there is a significant difference between Snapdragon 821 and Snapdragon 820, and whether it is worth upgrading. Let’s first make an intuitive comparison between the two CPUs through a parameter table.

In fact, even from the naming of the product, we can It can be seen that Snapdragon 821 is only a slightly upgraded version of Snapdragon 820. From the parameter table above, we can also intuitively see that Snapdragon 821 mainly improves the main frequencies of the CPU and GPU. Judging from the official data, CPU performance has increased by 10%, GPU performance has increased by 5%, and power consumption has decreased by 5%. Overall, although Snapdragon 821 has a certain performance improvement compared to Snapdragon 820, the improvement is limited. In terms of user experience, the difference should not be too big.
Judging from the AnTuTu running score results, the score of Coolpad Changer S1 is just in the first echelon. Although there is a slight gap compared to Le Pro 3 and Xiaomi 5S Plus, in terms of actual experience, the difference is not big. The running score of the Snapdragon 821 mobile phone is only about 1W points different from that of the Snapdragon 820, and there will be no significant difference in the actual experience. Therefore, you don’t have to worry about whether to choose Snapdragon 820 or Snapdragon 821, because there is no obvious performance gap between the two.
"Camera image quality test
As for the camera, the Coolpad Changer S1 uses the Sony IMX298 CMOS that is commonly used in flagships this year. For this CMOS is used in all major flagship mobile phones this year.
In terms of hardware, Le Pro3 uses a 16-megapixel camera, F2.0 aperture, PDAF phase focusing, DTI pixel isolation technology, and dual-color temperature LED fill light. In terms of configuration, the Coolpad Changer S1 does have flagship-level camera hardware.
In terms of camera functions, Coolpad Changer S1*** has four modes, namely slow motion, video, photo, and panorama. The camera interface displays intuitively. In addition to basic parameters such as exposure value, white balance, and ISO, you can also adjust contrast, sharpness, and saturation in real time, which is very convenient. Let’s take a look at the actual shooting level of Coolpad Changer S1 through sample photos. (Click on the picture to view the original picture)
Since the IMX298 CMOS has been installed in many flagship mobile phones, it is difficult to debug during debugging. It has been quite mature. You basically don’t have to worry about the camera quality of this phone. The biggest highlight of Coolpad Changer S1 is its excellent background blurring ability and relatively stable white balance performance. The problem is that the color palette is a bit bland and not too eye-catching.
"Coolpad Changer S1 external listening test
It needs to be mentioned that as a "changer", Coolpad Changer S1 has put a lot of effort into audio technology. It adopts With dual speakers and a dual-integrated sound cavity design, the top earpiece can also produce sound and create a stereo effect. In addition, Coolpad Changer S1 is equipped with independent smart amplifiers for both speakers, which greatly increases the volume and makes the speakers more efficient. It can still achieve low noise floor and high dynamic output at the highest loudness, reduce signal distortion, enhance low-frequency performance, the sound range is crisp and thick, the timbre is refreshing and not harsh, and the three-dimensional effect is stronger
In addition, it is compatible with Harman Kardon. Cooperation with Coolpad Changer S1 has obtained the support of three technologies, namely Clari-Fi lossy sound source repair algorithm, Clari-Fi lossy sound source repair algorithm and LiveStage Headphone headphone sound field widening algorithm. The former can maximize the sound field through the algorithm. It can restore the compressed details of MP3, WMV and other audio formats to a certain extent, which can effectively improve the sound quality; Clari-Fi uses software algorithms to achieve stereo effect for non-stereo audio, which allows users to have a better experience when watching movies or playing games. A good immersive experience; the latter uses algorithms to correct the position of the headphone sound field, improving the problem that the headphone sound field is located in the center of the head, so that the sound field expands forward and upward without causing a "head banging" feeling.
Since the video was shot without professional audio equipment, there was a certain loss of sound quality, and the stereo effect was not obvious. However, the external sound capabilities of the Coolpad Changer S1 still shocked me. Not only is the sound loud, but it also ensures that the bass is thick, the treble is not harsh, and the vocals and accompaniment are clearly layered, which is not easy to achieve.
"Evaluation Summary
" Harman Kardon's. Tuning, AKG N18 customized headphones, LeTV’s ecological content, and top-notch 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. Point. Judging from the current mobile phone market, young people are the most demanding of mobile phones and have the most purchasing power. The Coolpad Changer S1 aims at the problem of poor sound quality in cost-effective mobile phones while ensuring that its overall performance is the same as that of competing products. It provides a comprehensive solution, which can be said to have captured the pain points of consumers.
The editor was lucky enough to get this phone before the launch. After a few days of use, I found that the Coolpad Changer S1 made it easier to use. My impression of the Coolpad brand has completely changed. The Snapdragon 821 + 4070mAh battery makes performance and battery life go hand in hand. The exquisite and practical EUI and the excellent imaging level make me very comfortable and comfortable to use. On this basis, the audio performance has changed for Coolpad. Bonus points for S1, I can hardly find its shortcomings. If I have to find faults, the exterior design could be bolder.
