On April 23, 2014, Yijia Mobile officially launched its first flagship product in Beijing Wukesong MasterCard Center, adhering to the product concept of "no compromise" and "let good products speak". The emergence of Yijia Mobile Phone X has broken the rhythm of one new phone a year, which is also a new attempt of Yijia Mobile Phone. Yijia Mobile Phone X doesn't focus on hardware or price. It is only for people who prefer small size, which gives us a new understanding of Yijia Mobile Phone. Today brings you a comprehensive evaluation of this small and beautiful Yijia mobile phone X. Let's see if this mobile phone can also bring us some surprises in terms of performance in addition to its high appearance!

[Unpacking]

▲ Yijia Mobile Phone X uses a white paper packaging box. There is a Yijia logo with white characters on red background on the top of the front of the packaging box, a large white "X" logo in the middle, and the logo of "OnePlus X" is printed on both sides of the packaging box.

▲ The bottom of the packaging box uses bright red color matching, and there is a white label at the bottom, which is printed with some information about the color, capacity and manufacturer of the mobile phone, but the performance configuration of the mobile phone is not printed here like most mobile phone manufacturers, which looks cleaner.

▲ Open the box cover, you can see a phone X lying inside. Except for the box cover, which uses white color matching, other parts of the box use red color matching. The mobile phone is fixed on the top through the buckles at the upper and lower ends, which is different from the packaging method of most mobile phones. You can feel the uniqueness of mobile phones everywhere.

▲ Take out the red base on which the mobile phone is placed on the upper layer, and we will see a red paper box with a mark printed on it. Inside is the instructions and warranty card of the mobile phone. Inside the base on which the mobile phone is placed is also a hidden mystery. Inside is the card taking pin and the mobile phone case. The USB charging cable and charging plug of the mobile phone are neatly placed on the lowest floor.

▲ The charging line of the mobile phone adopts the red noodle line design, and the charging line also has its own harness. The details are very intimate. The output of the charging plug is 5V2A. Although it does not support intelligent fast charging, it can also quickly replenish the power of a mobile phone X.

▲ Finally, let's have a family photo of mobile phones and accessories. There are one phone plus X, one instruction manual, one warranty manual, one charging plug, one USB charging cable, one card taking pin and one mobile phone protection soft cover. We don't have a standard headset, but we have already affixed a film for us when we leave the factory, and then brought a mobile phone protective cover to ensure that we can use it directly when we start, It is also very good.

[Appearance appreciation]

▲ The film has been pre pasted for us before the mobile phone leaves the factory. After the film with "OnePlus X" logo on the surface is removed, I can start to use it. There is no need to buy another film.

▲ Yijia Mobile Phone X is equipped with a 5.0 inch 1080p Super AMOLED full HD display, which is thinner and more power saving. The surface is covered with 2.5D radian glass, and the touch of the screen edge is more comfortable.

▲ The size of the mobile phone body is 140mm * 69mm * 6.9mm, and the metal frame with 14 fine Arles texture processing makes the whole machine look simple, light and beautiful, pleasing to the eye, thin and exquisite, and fits the palm.

▲ At the top of the front of the phone, from left to right, there are 800W pixel front camera, earpiece and sensor. There is also a hidden LED breathing light at the top right corner, which is invisible at ordinary times. It only lights up when there is information prompt or charging. On the top of the phone, there is also a 3.5mm headphone jack and a noise reduction microphone jack.

▲ At the bottom of the screen are three virtual keys, from left to right: multi task key, HOME key and return key. Short press the "multi task key" to enter the recent task management interface. Moreover, the "multi task key" and the "return key" can be exchanged to meet the needs of different people, which is very considerate. However, there is no backlight for these three virtual buttons, which will be slightly inconvenient at night or in case of insufficient light.

▲ There is a Micro USB socket in the middle of the bottom of the phone, and two rows of external speaker holes are placed on the left and right sides respectively. However, after actual testing, only the left speaker occurs, and the right speaker is just decoration, which seems to be the design method of many mobile phones at present.

▲ The zirconia ceramics on the back of Yijia mobile phone X are delicate, dense, abrasion resistant, scratch resistant, smooth to the touch, and have good appearance and feel. Especially under the sunlight or other light sources, the luster is shining. There is a gold one plus logo in the middle of the back cover.

▲ There is a 1300W pixel rear camera in the upper left corner of the back of the phone, which uses dual ISP image processors and supports PDAF phase focusing. Below the camera is an LED flash. The rear camera is completely flattened. I'm not worried that the camera will be damaged if the phone is flattened.

▲ The side of Yijia mobile phone X uses a metal frame in rose gold color, and has undergone 14 fine Arles texture processing, making it more smooth to the touch. There is a sliding key on the left side of the phone border. This is an original three-stage Do Not Disturb key, which can switch between mute, Do Not Disturb and ringing. However, if you wear a protective sleeve, the operation is slightly less smooth.

▲ The volume increase/decrease button, switch key and SIM card slot of the phone are all concentrated on the right side of the phone. The top is a SIM slot. One plus phone X supports double open and double wait, Only Micro SIM can be placed in the SIM1 slot, and Nano SIM or Micro SD card can be placed in the SIM2 slot, which supports the storage expansion of up to 128GB SD card. The volume key is located below the SIM slot, and the integrated design is adopted. The power key is located below the volume key, and the workmanship of the keys is also very detailed. In these small details, we also pay attention to them.

[H2OS experience]

▲ Yijia mobile phone X is customized based on Android 5.1.1, adhering to the new Material Design style, and adding the hydrogen expression, hydrogen window and sliding beauty of Yijia. Many improvements have been made, many experiences have been upgraded, and the operating system is not worried. Let's experience the H2OS system in Yijia Mobile X.

▲ On the main page of the system, we can see that the default background wallpaper of the system is black, which should be specially customized to match the ID borderless of Yijia Mobile X. The system icons have been redesigned and optimized, and the interface looks very simple as a whole. The lock screen interface can display the time and date, and swipe left to quickly enter the camera interface.

▲ The dialing interface of Yijia Mobile Phone X is very simple. The system uses a gray background by default, and also integrates the "life service" function. The SMS content interface uses a white card display, which is more intuitive under the black background. For some service type SMS, you can even directly perform related operations in the SMS, such as charging the phone, It is suitable and convenient to use.

▲ In the main interface of the system, slide down from the top of the screen to enter the notification interface, slide down from the blank of the screen to enter the "global search" interface, and slide up from the bottom of the screen to enter the shortcut toolbar interface.

▲ The alarm clock, calendar and weather function systems commonly used in daily life have also been preset for us. The calendar supports the addition of schedule reminders, and the weather can check the weather conditions of the last week. Of course, this is not a special feature if we just talk about the function, but H2OS has redesigned these commonly used plug-ins to make us look more clear at a glance, We can quickly find what we want.

▲ The system has its own one plus store, where we can directly download applications and games, and also conduct ranking and classification operations for the applications and games, which can help people quickly find the applications or games they want, but the application and game resources still need to continue to be enriched and optimized, It would be more convenient if it could support a search link outside the store.

▲ There is no theme store in the H2OS system of Yijia Mobile X, but we can download and import by ourselves, and the system also preset some wallpapers for us, but different from the background wallpapers of other mobile phones, the mobile wallpaper of Yijia Mobile X is only displayed in the upper 33% of the mobile phone. On the main page, long press the hydrogen window to enter the wallpaper replacement interface, and touch the hydrogen window, Oneday will show train tickets, boarding passes, movie tickets and other information in the form of cards.

▲ The H2OS system in Yijia Mobile X has no built-in security center function, only one "Yijia Doctor" option, which includes five options: remote service, technical support, help center, screen detection and after-sales service. However, it is a little pity that traffic monitoring, virus detection, SMS interception, garbage cleaning and other functions have not been added, Fortunately, we can do this by downloading third-party security software.

▲ There are three physical touch keys at the bottom of the front of Yijia mobile phone X. In addition to the HOME key in the middle, the functions of the keys on the left and right sides can be set by themselves. Enter the "Advanced Settings" interface of the "Settings" option, and set through the "Key Customization" option.

▲ In addition, we can also carry out black screen gestures, timed power on/off and somatosensory settings. However, if you want to carry out music control in the black screen state, you must first turn on the pre installed Netease Cloud music in the system. If you do not turn it on, you cannot directly carry out music control operations.

[In depth experience]

"Performance score"

▲ One Plus Mobile Phone X uses Snapdragon 801 processor, Adreno 330 GPU, and 3GB running memory. You should be familiar with Snapdragon 801 processor, which is the configuration of last year's flagship model. Now let's conduct a simple test of mobile phone performance through data. Although the era of competing for running points has passed, running points can reflect the performance of a mobile phone in some ways. The following two software programs, Anthare and Master Lu, were selected to test the running points of one plus mobile phone X. Anthare scored 47714 points, while Master Lu scored 38529 points. From the point of view of the score, it belongs to the middle level, However, it is enough for daily use.

『 Graphic processing test 』

▲ Now let's test all aspects of the performance of Yijia Mobile Phone X through some professional test software. NenaMark2 is a hardware accelerated benchmark test program for Android devices. It tests the graphics capabilities of mobile phones by demonstrating a real-time rendered image, including reflection, dynamic shadows, surface parameters, complex light modes, etc. The test result of NenaMark2 is 58.7fps. From this score, we can see that the graphics processing capability of Qualcomm Adreno 330 GPU is still good.

『 Video test 』

▲ The following is a simple test of the video playback capability of Yijia Mobile X, and the video player provided by the system is still very powerful. The test results show that basically all video formats are supported, and only three video formats are not supported. However, the player of the system is hidden and can only be enabled when you play the video, For online movie and television viewing, the system has preset Tencent videos for us. The content is good. Of course, if you don't like it, you can uninstall it.

『 Signal test 』

▲ Yijia Mobile Phone X uses a metal frame, which has an impact on signal transmission. What is the signal strength of Yijia Mobile Phone X? Let's test whether it has an impact on network signal transmission through software. The test shows that there is basically no impact on wifi signal transmission, but the network signal can only reach - 104dBm to - 107dBm indoors, while the signal is good outdoors, which can reach - 90dBm to - 101dBm, but there are not many full frames, so it can still affect signal transmission, However, there was no disconnection in daily call use.

『 Battery test 』

▲ Yijia Mobile Phone X is equipped with a 2525mAh battery. For the 5.0 inch 1080p large screen, the battery is actually a little small. There is no battery with larger capacity, which may be related to the ultra-thin body. A simple test was made on the power consumption of Yijia mobile phone X. Here, the power consumption test method of watching videos was adopted. The volume was 50%, and the brightness system was defaulted. After 30 minutes of continuous video playback, the power consumption dropped from 37% to 30%, and the power consumption was 7%. If you are not a heavy user, it can be achieved in one day.

▲ The charging efficiency is simply tested. To make the data as accurate as possible, the original 5V2A charging plug in the packaging box is used for charging test. After 10 minutes of charging, the power has increased from 21 to 32%, and the charge power is 11%. It takes about 2 hours to fully charge. Since the mobile phone does not support fast charging, the result is also good.

[Camera test]

▲ The camera shooting interface of Yijia Mobile Phone X is very simple. The big round "shooting key" in the middle is very eye-catching. The countdown key is on the left side of the shooting key, and the shortcut key is on the right side, which can quickly start the operation of beauty, HDR and high image quality; Slide the camera to the right to enter the more options interface, where you can switch between delay, slow motion, photos, videos and panoramas; The camera's setting interface is also very simple. You can only set the photo resolution, save position, shutter sound and grid.

▲ The playability of Yijia mobile phone X camera is general, and it is certain to meet daily use. Since my photography level is really not high, I will directly take some photos here without any analysis. The following are most of the samples taken in the automatic mode of the camera, only for size modification. In sunny weather, the pictures taken in the automatic mode have good definition, and can also restore the original color of the scene more realistically. The following are the samples taken outdoors in the automatic mode.

▲ The rear camera of Yijia mobile phone X is 1300W pixels with a large aperture of F2.2, so the background is still good when taking close range pictures. However, if you want to take pictures with good illusion effect, you must also use manual focusing to make it easier to achieve.

▲ At last, I made a simple test for the camera's night scene shooting. Night scene shooting has always been the weakness of the phone. If you use the automatic mode of the phone to shoot, the noise is still obvious. But if you use manual focusing more often, you may have unexpected effects, The last picture is taken through manual focusing. The noise is better than that in automatic mode.

Summary

After just over a week's experience, I have a simple understanding of Yijia mobile phone X. In terms of appearance, Yijia mobile phone X adopts double-sided 2.5D radian glass, which fits the thin body and integrates with the metal middle frame. In terms of appearance design, it adheres to the design concept of "not making do with" of Yijia mobile phone, and does not compete with other mobile phone manufacturers, but does a good job of each mobile phone. In terms of appearance, It is not too much to call it the flagship of 1000 yuan. However, in terms of the system, there is still a lot of room for optimization of H2OS in Yijia Mobile X. In the past few days, the system has a good fluency, which may also be the reason why I first came into contact with H2OS. The system really feels light, but it seems to lack many convenient and practical functions, without its own music, video player and theme store, Some young people may feel a little inconvenient. It's a little pity that we don't have the current popular fingerprint recognition and all metal body. We have been using the machine equipped with fingerprint recognition for a while. For fingerprint recognition, once we get used to it, it's really not suitable to switch back to the machine without fingerprint recognition.
