It was originally thought that Yijia mobile phone X would be a 1000 yuan model. When the price was announced, few people expected that its price would be as high as 1499/1599 yuan. So what's special about this Yijia mobile phone X using Snapdragon 801? It's a false high price? Or a low-key true light flagship? Let me take you to analyze this lightweight flagship phone in simple terms.
Yijia mobile phone X uses a 5-inch 1080P AMOLED screen, with 2.5D glass on both sides of the body, metal frame, Snapdragon 801 SoC, 2G/3G RAM+16G ROM (eMMC 5.0 flash memory, supporting Micro SD card expansion), 8 million front+13 million rear cameras, Samsung S5K3M2 (supporting phase focusing) as the sensor of the rear camera, 2500mAh battery capacity, dual Netcom dual card dual standby. This time, Yijia Mobile Phone X uses a rare design of double-sided 2.5D glass, which is totally different from the previous style of black rock sand.
appearance
Yijia Mobile Phone X is still packed in a compact paper box, and its contents include a filmed Yijia Mobile Phone X, a data cable, a charging head, a silicone phone case, a manual, a free film sticking card, and a pin.
The 3.5mm headphone interface of Yijia mobile phone X is located at the top of the phone, while the bottom is a symmetrical speaker outlet (actually only one is making sound, and the other is just for decoration). The Micro USB port is in the middle of the speaker, and the bottom forms a symmetrical structure.
This one in our hand is a 3G standard version of Yijia mobile phone X. Its metal frame has a stripe texture (Arles texture), while the 2G basic version does not.
You can clearly see the film that comes with the phone
One plus mobile phone X uses 2.5D glass, coupled with the AMOLED screen, which has a strong ID flavor without borders. The phone's face value is high when the screen is not lit. This double-sided 2.5D glass has a really good grip, which is no less than a phone 2. The gap between the double-sided 2.5D glass and the metal middle frame is very narrow, which can be seen from its workmanship.
The charging head of Yijia mobile phone X is 5V===2A, the data cable is still noodles shaped, and the materials used for accessories are very generous.

In terms of the screen, the maximum brightness of the screen of Yijia Mobile X is about 350 nits at the bottom corner of the screen, while the center brightness of the screen is about 300 nits. The brightness is slightly uneven, and the visual angle performance is about the same as that of the MX5. Both visual angles are good. In terms of color gamut, Yijia Mobile X uses an AMOLED screen, whose color gamut covers 100% sRGB, 100% Adobe, the default color temperature is 9800K, the color temperature is slightly cold, and the average △ E is 1.41. There are few such accurate color restores in the AMOLED screen. Although the color temperature is slightly high, the color temperature value can still be set in the settings. In general, this is a good AMOLED screen.
System UI
Yijia Mobile X uses the hydrogen OS of Android 5.1.1, which may be to cater to the AMOLED screen. The whole theme of Yijia Mobile X is dark and black. Compared with other manufacturers' systems, Yijia's hydrogen OS is very pure and simple, with very few applications, and also has a file manager.
performance
In terms of performance, the 2.3GHz Snapdragon 801 of Yijia Mobile Phone X is really not good today. Its performance is lower than last year's Xiaomi 4 (2.5GHz Snapdragon 801). At the same time, its performance in flash memory reading/writing is also average. Although it uses eMMC 5.0 flash memory, its speed is not as good as that of the ZUK Z1 and MX5 of eMMC 5.0. Obviously, from the perspective of performance and configuration alone, Yijia Mobile Phone X is not a high cost performance mobile phone. From the perspective of performance alone, many famous domestic brands have mobile phones with the same configuration cheaper than it. However, the Snapdragon 801 is still able to cope with the daily use today. At present, the bottleneck of the smart phone is mainly the flash memory and memory.

In the first group of daytime scenes, in terms of white balance, Magic Blue Metal>One Plus Mobile X, and in terms of analytical power, Magic Blue Metal causes uneven light in some red buildings due to the background. The application algorithm of Magic Blue Metal mistakenly damages some details of the red building, making some details look like fog.

In this group of samples, Yijia Mobile X performs best.

In this group of scenes, in terms of white balance, the whole shooting scene at that time was cold, while the white balance of Yijia Mobile X was a little excessive, but at least it was obvious cold colors, while the Magic Blue metal directly turned into warm colors. In general, although the white balance of both was slightly different, Yijia Mobile X was better than the Magic Blue metal. In terms of analytical power, Yijia Mobile Phone X>Meilan metal.

In this group of scenes, in terms of white balance, the performance of these two mobile phones is very similar, which can restore the real scene well. In terms of color, the color performance of potted leaves is not much different between the two. However, we can see that the two mobile phones are overexposed in the leaves. In this group of samples, the performance of both mobile phones is not ideal.

In this group of samples at night, in terms of white balance, Yijia Mobile Phone X>Meilan Metal, and in terms of noise control, Meilan Metal>Yijia Mobile Phone X, we can clearly see that there are black and white noise spots on the wall in Yijia Mobile Phone X's photos, which is very obvious. Although Meilan Metal also has black and white noise spots, it has obviously been optimized by the smearing algorithm, It is better than one plus mobile phone X.

In this group of ultra weak light scenes, we can see that there is a large point light source at the construction site, which can test the anti glare ability of the two machines, and we can clearly see that the glare of Magic Blue Metal is relatively serious, while the anti glare aspect of One Plus Mobile Phone X is much better. One Plus Mobile Phone X>Magic Blue Metal.
It should be noted that if the camera lens is dusty or dirty when taking photos, the glare probability is very high. As a result, the lens must be wiped clean when doing glare tests, and cotton clothes can be used.

In this group of samples at night, in terms of white balance, Magic Blue metal>One Plus mobile phone X, and in terms of noise control, One Plus mobile phone X>Magic Blue metal, we can see that One Plus mobile phone has used a very suitable smear algorithm in this scene, effectively reducing the noise of the picture.
In general, the camera of Yijia Mobile Phone X can reach the level of mobile phones at this price, and its camera quality is better than that of ordinary thousand yuan mobile phones. For more detailed camera evaluation, please see《 》。
Endurance&fever
In terms of battery life, Yijia Mobile Phone X uses a 2525mAh battery. Its power down level is somewhat higher than we expected. After a three-and-a-half hour high-intensity endurance test, its remaining power is only 47%, which is considered to be poor among the machines we have tested. Maintaining such a level of endurance for a day may be under some pressure.
In terms of heating, after running NBA2K14 for one hour, the maximum temperature of the mobile phone was at the upper left corner of the mobile phone screen, with the temperature up to 45.5 ℃. During the test, when I ran NBA2K14 for about 20 minutes, I had clearly felt that the mobile phone was rapidly warming up. It seems that this 2.3GHz dragon 801 is also a small fire dragon.
summary
One plus mobile phone X positioning is a lightweight flagship, and its price is also in the 1500 yuan range. From the aspects of its screen, camera, and body workmanship, it really reaches the expected level of mobile phones at this price point, or even better. But if you are a user who pursues cost performance and mobile phone performance, it will not be attractive. There are many SoCs at the same price point, With a higher configuration, some thousand yuan phones even have fingerprint recognition and fast charging functions, so Yijia Mobile X is not a key cost-effective product. It is a mobile phone that provides a quasi flagship experience for users who do not follow the performance.
