The traditional manufacturers of Internet transformation Coolpad change S1 review

IT168 evaluation mentioned Coolpad brand, I believe that up to 99 down to just will go, basically no one knows no one knows. Although it is a joke, but this is closely related to the Coolpad years of channel precipitation. However, as a traditional cell phone brand relying on carriers to start, under the wave of the Internet, was suppressed by many emerging cell phone manufacturers. Since Liu Jiangfeng took over as CEO of Coolpad, Coolpad's brand image has undergone a sea change. Through the Cool brand, Coolpad strengthens its user-centric business philosophy and realizes a strategic transformation in the true sense of the word.

The birth of the Cool brand is a product of Coolpad's transformation process, and the new brand image is closer to young consumers. With a more fashionable appearance, advanced features, excellent performance, and ultra-low price, the Cool 1 dual released some time ago is a good interpretation of Coolpad's latest brand image. This review of Coolpad Changers S1 is an extension of the product line based on the Cool brand concept. Positioned more high-end, to meet the requirements of higher hardware performance and music quality of the crowd.

The Cool Changers S1 not only adopts the Qualcomm Snapdragon 821 top chip, outstanding performance. At the same time, Coolpad has also cooperated with Harman Kardon to provide music technology support for the phone, so that whether it is played externally or wearing headphones, users can get a better listening experience. In addition, as a flagship phone, the performance in terms of photography and battery life is naturally not bad, and we will first make an objective assessment of it through the parameter information below.

From the parameter table, the multimedia performance of Coolpad Changemaker S1 is its biggest strength, which includes the **** same role of hardware and software. Snapdragon 821 chip as well as large memory to ensure adequate performance support, software, Harman Kardon for its sound quality debugging, LeTV system also enriches the multimedia resources, on the whole, to provide users with comprehensive support from the content to the hardware, and accurately catch the consumers complain about the poor sound quality of the phone this pain point.

It should be noted that the Coolpad Changers S1 eliminates the traditional 3.5mm headphone jack and has built-in AKG N18 custom headphones as well as a Type-C adapter. In other words, you can't realize listening to songs and charging at the same time with headphones without the help of accessories. But the good thing is that it supports QC 3.0 fast charging and is capable of outputting CDLA full digital lossless audio through the Type-C port for better sound quality.

"Thin and light body + excellent grip

The industrial design of Coolpad's cell phones always impresses us with its sharp angles and hard lines. This design style is obviously biased towards the aesthetics of mature men, which is not in line with the current fashion trend. After the strategic transformation, this aspect of the design style is obviously diluted, and Cool brand by LeTV and Coolpad cooperation to create, so in the Coolpad change S1 design also introduced elements of LeTV.

The Coolpad Changemaker S1 features a 5.5-inch LCD display with 1080p resolution level. Not only does the screen edge have 2.5D curved surface excess, and the display effect is very delicate, in the normal viewing distance can not see the grain feeling. Overall, the design of the Coolpad Changemaker S1 follows the principle of full symmetry. The earpiece part of the integrated front speaker, and the speaker at the bottom of the body can sound at the same time, creating a stereo effect. The sensors on both sides of the earpiece and the camera are symmetrical and of the same size, and the combination of the light sensor and the distance sensor eliminates an unnecessary hole, making the front look more concise. In addition, the tip light and the three physical buttons at the bottom have been designed to be hidden for visual unity.

The ID bezel-less design creates a visually edgeless effect when the phone is off, but the obvious black edges when the screen is on are very distracting. The Coolpad Changemaker S1 does not use ID bezel-less design, and the bezel control is also very good. However, it should be noted that there is no plastic buffer between the screen and the metal frame of the phone, the risk of screen breakage is higher when the phone falls, we recommend wearing a protective cover or buy broken screen insurance.

There are only two holes on the top of the Coolpad Changeling S1, one for the infrared sensor, which allows the phone to function as a remote control. The other is a noise-canceling microphone. The traditional 3.5mm headphone jack has been eliminated, and headphones can only be connected to the phone through the Type-C port at the bottom of the body. Also from this photo we can see that the Coolpad Changemaker S1 has a CNC-cut center frame and a curved transition on the back of the body, which makes it feel very good in the hand, and you won't feel cut in your hands.

Bottom of the body, Coolpad Alter S1 adopts a symmetrical design, the left and right sides are still the speaker and microphone openings. In addition, the advantages of the USB Type C port should already be very well known, which supports faster data transfer speeds and greater charging current, and is a quasi-successor to the regular Micro USB port. It is worth mentioning that, after canceling the 3.5mm headphone interface, the Coolpad Changemaker S1 fully supports the CDLA standard (full digital lossless audio), in addition, in order to facilitate the compatibility of the user's existing audio devices, the phone comes with a Type C to 3.5mm audio interface adapter.

The Coolpad S1's body has been sandblasted to retain the original texture of the metal body, and has a nice feel in the hand. The camera part is still raised, and the fingerprint identification button is also a mirror design. The bottom of the LOGO is more interesting, COOL brand is greatly emphasized, it is below the LeEco inside, coolpad and harman/kardon (Harman Kardon logo). The Coolpad brand is greatly downplayed, instead highlighting COOL and this time the main harman/kardon.

Overall, the exterior design of the Coolpad Changer S1 is not unique, and basically doesn't jump out at you, except for the lack of ID bezel-less on the front, and the lack of a brushed-metal design on the back. But despite this, these two changes are really what many consumers are desperately looking for.

"Android 6.0-based EUI 5.8

The Coolpad Changeling S1 has a software boost from LeEco, which can be considered a worthwhile leap in user experience. The EUI created by LeEco has always been committed to creating a "borderless" ecosystem. After more than a year of iteration, the degree of perfection of EUI is already comparable to MIUI, Flyme, such as the depth of customization of the system, and has some of its own unique selling points. The Coolpad Changemaker S1 comes with EUI version 5.8 based on Android 6.0.1, under which Coolpad has specially customized a set of icons with Harman Kardon wallpapers, making the overall interface more colorful and stylish.

In addition to the default theme specially customized by Coolpad, EUI itself also has two additional built-in themes, Gorgeous and Elegant, to choose from. The system theme also supports customization, and you can choose fonts freely. Although the degree of customization is not as high as that of the old Chinese Android UI such as MIUI, this ensures the unity of the system theme to a certain extent.

With regard to basic system functions, EUI 5.8 further enriches the system's functionality and usability, with global search, WeChat, dialing yellow pages, and other features that are basically standard on domestic Android UIs. What's a little different is that in the global search, EUI integrates more resources, such as searching for "Xue Zhiqian", then its related materials, videos, music, APP and so on will appear in the search results.

What's worth mentioning is that for young users, catching up with dramas, football, and celebrities is a must, and the calendar in EUI 5.8 allows users to keep track of the information they want. For example, if you follow Kevin Yu, then if there is a recent movie, TV show or new single from him, it will appear in the user's calendar as a reminder. Of course, you can also follow a favorite team or even an LOL player. Since LeTV Pictures has a lot of celebrities under its umbrella, the phones with EUI have become no less than star chasers, with celebrity homepages, ringtones, emojis, and photo wallpapers available in EUI 5.8.

The biggest feature of EUI is the integration of LeTV's rich video content service. LeSee desktop and Live desktop can be accurately personalized push according to the user's search behavior and historical data.Live desktop is the essence of EUI, when the Live desktop is turned on, the phone will be automatically switched to landscape mode, and the user can watch satellite TV live broadcasts, celebrity stations, movies, TV dramas, variety shows and so on in this desktop. The screen defaults to nine-way video, allowing three live streams to be played simultaneously.

The main interface of EUI actually integrates a lot of apps, such as LeTV Headline, LeSee Video, and LeTV Sports, each of which is an entrance to the LeTV ecosystem, so that there is no need to frequently switch apps within the LeTV ecosystem, and users can access other related apps through their personal interests, and what they think is what they get. This is also a concrete embodiment of the ecological reaction and breaking the APP silo that LeTV has been emphasizing.

Coolpad Change S1 system interface

EUI 5.8 has been y optimized for power consumption and performance on the basis of Android 6.0.1, and the Snapdragon 821 platform further guarantees the smoothness of the system. After a few days of experience, EUI 5.8 is satisfactory in terms of stability and smoothness. But in the experience, LeTV and rich resources and content is more impressive.

"AnTuTuRabbit score test

The Coolpad Changemaker S1 in this review is the version with Qualcomm Snapdragon 821 processor, 4GB of running memory, and 64GB of onboard storage. I'm sure there are quite a few of you who are struggling with whether the Snapdragon 821 is significantly different compared to the Snapdragon 820, and whether it's worth upgrading. Let's start with a visual comparison of these two CPUs through a table of parameters.

In fact, even from the naming of the product we can see that the Snapdragon 821 is just a minor upgrade from the Snapdragon 820. We can also visualize from the parameter table above that the Snapdragon 821 is mainly an upgrade in the main frequency of the CPU and GPU. From the official data provided, the CPU performance has been increased by 10%, GPU performance has been increased by 5%, and power consumption has been decreased by 5%. Overall, Snapdragon 821 compared to Snapdragon 820 has a certain performance improvement, but the improvement is limited, specific to the user experience, the difference should not be too big.

From the AnTuTu score results, the Coolpad Change S1 score is just in the first echelon. Although compared to Le Pro 3, millet 5S Plus slight gap, but specific to the actual experience, the difference is not big. The Snapdragon 821 cell phone score and Snapdragon 820 score is only about 1W difference, the actual experience will not have a significant difference. Therefore, we can not be entangled in the Snapdragon 820 or Snapdragon 821, because the two did not open a significant performance gap.

" Camera imaging quality test

Camera, Coolpad change S1 using this year's flagship level on the commonly used Sony IMX298 CMOS, for this CMOS in this year's flagship phones have been applied. In terms of hardware, Le Pro3 adopts a 16-megapixel camera with F2.0 aperture, PDAF phase focus, and DTI pixel isolation technology, equipped with dual color temperature LED fill light. From the configuration point of view, the Coolpad Changemaker S1 does have flagship photographic hardware.

In terms of camera functions, the Coolpad Changemaker S1*** has four modes, namely slow motion, video, photo, and panorama. Camera interface display intuitive, not only can exposure value, white balance, ISO these basic parameters, but also real-time adjustment of contrast, sharpness and saturation, very convenient. Here we will pass the sample photos to see how the Coolpad Changemaker S1 actually level of real shooting? (Click on the image to view the original)

Because the IMX298 CMOS has been installed in many flagship phones, the debugging aspect has been quite mature. You basically don't have to worry about the level of photography on this phone. The biggest highlight of the Coolpad Changers S1 is the excellent background defocusing ability and the stable white balance performance. The problem is that the color palette is slightly bland and won't be too eye-catching.

"Listening to the Coolpad Changemaker S1

It should be emphasized that as a Changemaker, the Coolpad Changemaker S1 has put a lot of effort into its audio technology. It adopts dual speakers, dual integrated sound cavity design, the top of the earpiece can also sound, and can create stereo effect. In addition, the Coolpad Changers S1 is equipped with independent intelligent amplifiers for both speakers, which dramatically increase the volume and enable the speakers to achieve low bottom noise and high dynamic output even at the highest loudness, reduce signal distortion, enhance low-frequency performance, and have a crisp and mellow sound, with a refreshingly unobtrusive tone and a stronger sense of three-dimensionality.

In addition to the cooperation with Harman Kardon, Coolpad Change S1 has gained the support of three technologies, which are Clari-Fi

lossy audio repair algorithms, Clari-Fi

lossy audio repair algorithms, and LiveStage

Headphone headphone soundstage widening algorithms. The former algorithm maximizes the compression details of MP3, wmv, and other audio formats, effectively improving sound quality; Clari-Fi

is a software algorithm that allows non-stereo audio to achieve stereo effect, which allows users to have a better immersive experience when watching a movie or playing a game; and the latter algorithm corrects the position of the headphone's soundstage and improves the soundstage of the headphone. The latter uses algorithms to correct the position of the headset's soundstage to improve the center of the head, widening the soundstage forward and upward without creating a "head banging" sensation.

Since the video was shot without professional audio equipment, there is a certain loss of sound quality, and the stereo effect is not obvious. However, despite this, I was still shocked by the Coolpad Change S1's ability to play out. It not only has a large stereo, but also ensures that the bass is thick, the treble is not harsh, and the vocals and backing vocals are layered, which is not easy to do.

"Review Summary

"

Harman Kardon's tuning, AKG N18 customized headphones, LeEco's eco-content, and top-notch hardware parameters, it's clear that Coolpad is bringing great sincerity to meet consumers again. And whether it's the selling point of the product or the marketing strategy, Coolpad has grasped the key points. With the current cell phone market, the youth crowd is the most demanding for cell phones, but also the most purchasing power. The Coolpad Changemaker S1 in the conditions to ensure that the comprehensive performance and competitors on a par, targeting cost-effective cell phones generally poor sound quality, to provide a full range of solutions, can be said to have seized the pain point of the consumer.

I was fortunate to get this phone before the launch. After a few days of use, I found that the Coolpad Changers S1 has completely changed my impression of the Coolpad brand. The Snapdragon 821+ 4070mAh battery allows performance and battery life to go hand in hand, and the beautiful and practical EUI with excellent imaging levels made my use of it very comfortable and smooth. On top of that, the audio performance adds to the Coolpad Changers S1, almost making it impossible for me to find its shortcomings. The design could have been bolder if I had to look for the bones.
