So as a newcomer, how will Coolpad perform to gain recognition from consumers?

"Appearance: Aviation-grade aluminum frame + nanomaterial back cover

Coolpad Master uses a fully laminated 7.0-inch black diamond screen with a resolution of 1920-1200 and a pixel density of 323PPI, which complies with the Retina screen standard.

▲Coolpad Master

This screen uses LTPS technology, with a viewing angle of 178°. In addition, the top of the screen is covered with third-generation Corning Gorilla Glass, which has better scratch resistance. Regarding the screen display effect of Coolpad Master, the author will explain in detail later.

Like the Coolpad Grand View 4, the frame of the Coolpad Grand Master is also made of aviation-grade aluminum and has a frosted surface. The use of this frame not only improves the appearance and texture of the fuselage, but also increases the strength of the fuselage.

▲Coolpad Master

In addition to the frame, the volume buttons, power button, mute button, memory card and SIM card tray on the Coolpad Master are also made of metal. , this kind of material is very rare among models under 2,000 yuan.

The measurements of Coolpad Master are 185*104*7.6mm, and the weight is 250g. For reference, the iPad mini2 with a 7.9-inch screen has dimensions of 200*134.7*7.5mm and a weight of 331g.

▲Coolpad Master

Judging from the author’s experience in the past few days, Coolpad Master can be carried around in pants, and general operations are performed with both hands. There is nothing special about it. A sense of harmony. In addition, carrying such a large mobile phone outside has the advantage of high repeatability.

Obviously, the Coolpad master prefers users who like large-size screens. There will definitely be players who will question this kind of large-screen machine. In this regard, it can only be said that radish and green vegetables have their own preferences, and the author prefers the former.

In addition to the workmanship of the fuselage, Coolpad has also put a lot of effort into communication signals. Coolpad Master supports WCDMA+GSM dual-SIM dual standby. For this reason, 5 antennas are integrated into the body, and they are all concentrated on the frame.

▲Coolpad Master

As you can see, the Coolpad Master adopts a segmented design both above and below the fuselage, and the antenna is located in the position of the segmented plastic strips. According to the author's actual measurement in the subway, Coolpad Master was able to obtain China Unicom's 3G signal at sites that were originally unable to access the Internet.

▲Cool Master

However, although this design signal is good, the appearance lacks beauty. Of course, in the face of better signals, this regret is still acceptable.

Coolpad Master is equipped with dual external amplifiers and supports Dolby sound effects. Whether it is games or movies, you can get a stereo sound experience.

▲Coolpad Master

In terms of buttons, Coolpad Master adopts the design of physical Home button plus touch menu and return button, and provides LED button lights, which is different from the main use of virtual buttons. Android tablet.

▲Coolpad Master

However, the Home button cannot wake up the screen, which is a pity. I hope the new version can improve it.

The back cover of Coolpad Master is made of nano-material, which feels quite comfortable and does not have the problem of fingerprints. However, the pure white back cover is more dusty, so I am looking forward to the black version.

Summary: In terms of body workmanship, Coolpad Master uses the same level of craftsmanship and materials as Coolpad Grand View 4, and The screen and back cover are even better than those of Coolpad Grand View 4. We must know that the price of the latter is 3,498 yuan, which shows that Coolpad Master is a model that pays great attention to workmanship, which is very rare among products of the same level.

"System Edition: Business-grade Security

CoolPad Master has installed its own deeply customized CoolLife UI 5.5, developed based on Android 4.2. To be honest, this version is a little bit old. I hope it will be official. The models on the market can be loaded with UI based on higher versions. It should be noted that the Coolpad Master in my hand is an engineering prototype, and the system version has been continuously updated since it was launched. Therefore, the following content does not represent the officially launched models, only. For reference.

▲Based on Android 4.2

Cool Master supports dragging at any point on the screen to unlock, so this operation can also be performed with one hand.

▲Swipe the quick check-in camera to the left

You can see on the desktop that the icons and widgets of Coolpad adopt a style that is more suitable for young people. In addition to being beautiful, it is also very practical. For example, the weather widget will display the current city. Iconic building

▲Young and fashionable desktop

▲Pendants are rich in color

▲Information waterfall

Cool masters are also users. It provides customized content for themes, wallpapers, and lock screen styles. I tried it and found that the resolution of the wallpapers is good, but the number of online themes is only 3, and I hope it can continue to increase.

▲The scale is a bit small. Big

The program menu of Coolpad Master uses a 5*4 grid display, and the management of the program is relatively simple. You only need to long press any icon to enter the editing state. Click the icon with an You can directly disable it.

▲The drop-down bar has rich options

Coolpad Master’s dialing keyboard has a one-handed mode, and users can select it as needed; in text messages, the volume can be increased or decreased. You can quickly adjust the font size by pressing the key. Both settings are quite user-friendly, especially the latter, which can take care of the elderly.

▲One-handed operation

Although. It is a model for young people, but Coolpad Master still has business-level security functions. Cool Butler can provide users with system-level security protection, such as phone tapping, traffic monitoring, file encryption, etc.

▲Encrypt any program

▲Put videos and photos into the safe box

Summary: Coolpad’s products have always been positioned for business. This time The launch of Master has added more young and trendy elements while maintaining the original business security.

However, in terms of fluency, the equipment of Coolpad Master needs to be optimized. I used 2GB of RAM as running memory, but the memory usage remained high, and the available memory was only 300~500MB. However, the author also found a solution, which was to disable all startup items through Cool Butler and found that the available memory could be reached after restarting. 900~1100MB.

Before optimization, the system would experience delays and freezes in program and interface switching from time to time. After optimization, this situation improved significantly. I hope Coolpad’s system engineers can carry out further optimization.

In addition, Coolpad Master has built-in 8GB ROM, but the author found that its reading and writing speed is not good. For example, after downloading a large game from Thumb Play, decompressing the data is time-consuming.

"Performance and power consumption: Game compatibility needs to be optimized

Coolpad Master is equipped with a 1.7GHz MT6592 eight-core processor, equipped with 2GB RAM and 8GB ROM. From Antu Judging from the Rabbit running score, this processor is at the same level as the Qualcomm Snapdragon 600 with the same frequency.

▲Coolpad master AnTuTu running score

Power consumption and heat generation. It has always been the strength of MTK processors, but due to the low temperature recently (only 12℃), this test focuses on the temperature rise from standby to high load.

The screen brightness is 100% and the installation is running in the background. In the Tutu stability test, the temperature rise of only 5°C in half an hour when the AnTuTu battery test is running in the front desk is commendable. In addition to the low room temperature, the Coolpad Master's large body space also allows heat to escape faster.

▲After half an hour of high-load operation, the temperature rose by 5℃

MT6592 embeds the latest Mali-450 display core with an operating frequency of 700MHz. Let’s take a look below. Game performance of Coolpad Master.

▲Click to play

Summary: Judging from the AnTuTu benchmark results, the performance of Coolpad Master is still at the mainstream level. However, in terms of games, since the Mali-450 display core has not been optimized by game manufacturers, there will be problems with texture errors or inability to run. I believe that this situation will gradually improve with the update of game versions.

"Screen article: Size/color/details beat 5C

Coolpad uses a 7-inch LTPS screen with a resolution of 1920*1200 and a pixel density of 323PPI. According to Coolpad official According to reports, the response speed of this screen is 3 times faster than Samsung Super AMOLED, the brightness and color saturation are increased by 20%, and the contrast is increased by 30%.

So what is the real performance of this 7-inch screen. ?

The above photos were all taken by the author using Canon 5D2 when traveling. It can be seen that the colors of the photos displayed by Coolpad Master are more vivid and more layered. , because the 7-inch screen of Coolpad also uses IPS technology, there is no overflow phenomenon while the saturation is increased, and the overall performance is quite natural for web browsing.

For web browsing, Coolpad has tablet properties. Once again, you can use the advantage to browse the Internet webpage without any pressure. However, please note that browsing the Internet webpage consumes more data.

▲Click to view the larger image. In terms of viewing angle, the official introduction of Coolpad Master is that it reaches 178 degrees.

▲Coolpad Master viewing angle test

The author conducted the test at an angle close to the horizontal line. The screen of Coolpad Master is reliable. The viewing angles are indeed very wide. The two sides of the fuselage are the best (when the fuselage is placed horizontally), which meets the needs of users when watching movies. Multiple people can also get a clear picture.

As mentioned earlier. Yes, Coolpad is equipped with dual stereo speakers and supports Dolby sound effects. Although it cannot be compared with speaker equipment, it is enough for portable audio and video equipment. Users cannot carry speakers around all day long.

▲7-inch screen + stereo sound amplification + Dolby sound effect test, it is recommended to wear headphones

Summary: Coolpad Master’s 7-inch screen does have an excellent visual experience. As a mobile film and television device, it is indeed It is an ideal choice. The author prefers to use Coolpad Master to share the results of photography, and believes that the slightly larger body size is worth it for the large-size high-definition screen.

"Photography: Insufficient details.

Coolpad Master uses a 13-megapixel main camera, supports F2.0 aperture, 28mm wide angle, and the minimum focusing distance is 3.9CM.

As for the camera interface, Coolpad Master provides users with a relatively easy-to-use operation method that does not require too many settings. The Coolpad master will also judge the lighting conditions of the scene and automatically select normal or low-light photography for the user. But what is strange is that in low-light scenes, after the system automatically selects low-light mode, it cannot be manually set to normal mode.

Judging from the sample, Coolpad Master’s color restoration is quite natural, but the photos The digitization and noise are relatively serious, resulting in a greater loss of details. However, what I have in hand is an engineering prototype after all, so the imaging quality of Coolpad Master still has a lot of room for improvement.

"Battery life

Coolpad Master has a built-in 4000mAh battery. For reference, the Coolpad Grand View 4 equipped with Tegra4 1.8GHz quad-core and 5.9-inch 1080 screen has a built-in 3000mAh battery. .

The author charged the Coolpad Master to 100%, and then played the online video for 30 minutes through WIFI; then the author opened "Asphalt 8" for trial play, which lasted about 42 minutes; finally, the author listened again. After listening to music for 15 minutes and browsing social software for 15 minutes, the following is the power consumption of these applications.

These applications were performed at 50% screen brightness and 50% volume, and the experience lasted for nearly 100 minutes. Finally, the Coolpad Master still has about 70% of the battery remaining. This performance is roughly the same as that of popular models nowadays, and the corresponding increase in battery capacity ensures the Coolpad Master’s battery life.
