|Preface  

From the Android king to the Android prince, from the overseas version of Xiaomi 4I to the domestic version of Xiaomi 4C, it has really gone through a long wait. However, the appearance of Xiaomi 4C seems to be the same as that of Xiaomi 4I, but the processor has been replaced by a non flagship but still powerful Snapdragon 808 six core processor, which is divided into the standard 2G+16G and 3G+32G high configuration versions. It supports edge touch on Xiaomi mobile phones for the first time, adopts Type-C interface that supports front and back plug, and supports "All Netcom 2.0" and the new MIUI7, So it's worth the wait! From the outside, Xiaomi 4C doesn't use mainstream metal body and fingerprint recognition, but it is more focused on providing a good user experience by combining its 5-inch body and the good-looking and easy-to-use MIUI7.

|Product unpacking  

For a long time, most Xiaomi mobile phones are packed in kraft paper. This time, Xiaomi 4C is packed in a more colorful orange package, which is more eye-catching. As a young editor, Xiaomi 4C prefers it.

The inner packaging is still orderly, and the power plug and Type-C It is still the same as the old black tone, calm and not exaggerated, but it is slightly less beautiful.

As the little prince of Android, Xiaomi 4C It also focuses on practicality. Xiaomi 4C adopts plastic body and integrated black glass panel, instead of the popular 2.5D arc edge glass. Under the rest screen, there is no suffocating aesthetic feeling, and the frame is not too narrow, but the black edge of the display screen is not wide. Personally, I feel that it has an ultra narrow frame, but it is more acceptable to have a racing horse display black frame.

Xiaomi 4C adopts a 5-inch 1080P full screen, the overall size is 138.1x69.6x7.8mm, and the weight is 128g. Such size and weight give users a good sense of grip, and it is easy to play with one hand.

Xiaomi 4C does not use the current popular 2.5D glass screen, but continues the suspension screen of the previous generation. When the light shines, you can see that the distance above the screen is , earpiece, front camera and breathing lamp.

There are three touch buttons at the bottom of Xiaomi 4C screen, and a blue backlight is provided, making it easier to operate in dark environments.       

Xiaomi 4C adopts a full enveloping body shell design. The body edge and the back cover are combined into one. The four corners and edges are arc shaped. When holding, it fits the palm of the hand and can be held more stably. Although the back cover is made of plastic material, the unique antifouling coating really lubricates the hand like baby skin, with a matte and delicate texture. The back cover has five colors of white, gray, yellow, blue, and pink. The color of candy meets different people's preferences. As a pioneer of the 80's, Xiaobian still likes a more calm gray.

Stainless steel metal buttons are used on the right side of the fuselage. The long ones are the volume plus and minus buttons, and the short ones are the power buttons. The buttons are bright, but it feels awkward when pressed. The damping is harder than Xiaomi NOTE, and the feedback is stronger. The feel is also different from person to person. SIM card slot is set on the left side of the fuselage.

Xiaomi 4C supports Micro SIM card. Xiaomi 4C supports "All Netcom 2.0". Mobile cards can be used together with Unicom cards and telecom cards. Any card can be used in 4G network, and the other card can be used in 2G network. In this way, users can not only choose operators and appropriate package combinations freely, but also let users who have separate work and life numbers say goodbye to having two mobile phones.  

In addition to 3.5MM on the top of Xiaomi 4C fuselage In addition to the socket, an infrared emission port is added. After downloading the Xiaomi remote control, it supports the infrared remote control operation of TV, box, air conditioner, SLR and other devices, which is of course very practical.

Xiaomi 4C became the first Xiaomi mobile phone to support the Tyce-C jack. With its Tyce-C power cord, you can plug in the front and back freely!

The rear camera is set at the upper right, and is equipped with a dual color temperature flash lamp and a laser focusing hole. If it is set here, it is not easy for the camera to be blocked by fingers in both horizontal and vertical shots.     

The lower middle part of the fuselage is also a simple metal MI logo. In addition, 114 sound cavity holes made by CNC drilling process are neatly arranged on the back of the fuselage. There is also a small supporting point about 1mm below the sound cavity hole, which can reduce the wear of the back cover of the phone on the table on the one hand, and also enable the sound to flow smoothly from the sound cavity hole.

|The screen is clear and transparent, with wide colors, and the sun screen and night light screen have a good experience

Xiaomi 4C adopts a 5-inch 1080P full HD screen, and provides up to 95% color gamut saturation. The color is strong, and the visual impact is very strong. In general, it is a very pleasing screen.

By comparing the photos taken by mobile phones with the actual environment, we can see that the colors will be more intense. In this way, the mobile phone screen is pleasing to the eye, but the color accuracy will be slightly different.    

Regardless of color, Xiaomi 4C screen has the advantage of its smart sun screen technology. In the above figure, the light from Xiaobian's hand can see that the phone screen is directly facing the strong sun. At this moment, the phone screen still remains clear, even reading small text is no problem. At the same time, the 4C also supports the night light screen technology. Through more accurate backlight adjustment, the minimum brightness can be reduced to 1cd/㎡. You don't have to worry about dazzling problems when you watch your phone for a long time in dark environments.

At the same time, the phone settings also support eye protection mode, color temperature and screen optimization settings. Through personalized settings, it can better meet the needs of different people and environments for screen display.

The display effect of Xiaomi 4C is good, but the video decoding ability of the mobile phone is insufficient. Through testing, it is found that some video formats have no sound, and some videos cannot be played. Fortunately, Xiaomi 4C usually focuses on online videos, which has little impact. However, if you download videos, you should consider the video format.

|Performance comparable to flagship: strong performance, low heat

Xiaomi 4C adopts the new generation 64 bit Snapdragon 808 platform, with built-in A57 and A53 high-performance computing cores and Adreno ™ 418 graphics processor. The high configuration version uses 3G dual channel high-speed memory and 32G storage, with excellent performance and lower power consumption. Compared with the previously criticized 810, the heating is somewhat alleviated.

1. In the evaluation of 64 bit v6 version of Anthare, the score is 5W6, which is much higher than that of Xiaomi NOTE with 801 processor. The performance is strong. It is not only sufficient for daily applications, but also easy to play games. At the same time, HTML5 scores more than 20000 in mobile web browsing performance test, and web page fluency is also great.

2. It is also the Master Lu's evaluation, which is a comprehensive evaluation of various mobile phone hardware and experience. Xiaomi 4C scored 5W, which has reached the level of the current flagship mobile phone, and its performance is still strong enough! The temperature is 33 ℃, within the normal range.

3. Vellamo is produced by Qualcomm and mainly tests the performance of JS and HTML5, which have a great impact on mobile browser experience. The most intuitive impact of the Vellamo test on users is the browser experience. The higher the score, the better the experience. Xiaomi 4C score: metal 2389, multi-core 2412, browser 4018. The score and ranking are high, and the temperature during the test is not high, the highest is 34.7 ℃.

4. 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 results of Xiaomi 4C show that its graphics processing ability is also quite good.

5. In the 3DMark Sling Shot test, the 1080P resolution ES 3.0 test was selected, and the score reached 1498. The performance was good. However, the temperature of the mobile phone also increased during the test, and the maximum temperature exceeded 40 ℃.

Xiaomi 4C has performed well in various performance tests, but running points is only one aspect, and actual experience is more important. How about its game performance?

Downloaded the best speed car test. Game loading time: 23.3 seconds. The game runs smoothly during trial play. After 15 minutes of trial play, the mobile phone temperature is 37.4 degrees Celsius, which is still within the tolerance range.

|The MIUI familiar to the system is still practical

MIUI can become the best Android Rom based on the original Android system in China. Its success lies in continuous optimization and update, and the development version is updated weekly. Moreover, the latest MIUI7 has been adapted to the full range of Hongmi models from the top to the low-end. At present, Xiaomi 4C also supports the stable version of miui7 based on. Of course, small editors prefer to use the development version to experience the MIUI system update in advance.  

The interface of MIUI7 is still fresh and simple, the UI is more flat, and the UI shape is consistent. This is undoubtedly a great blessing for me, who is not a Virgo who can't stand all kinds of UI shapes. The notification and setting menus use a pull-down ground glass interface.  

In terms of desktop management, MIUI supports short press of menu key to run memory cleaning, long press of menu key to support desktop sorting, wallpaper setting, etc., so that memory optimization and desktop sorting are more convenient.    

MIUI has powerful cloud services, convenient file management and rich yellow pages.

File management supports classification by type, and displays the latest files. It also supports one click cleaning and remote management, making it clear at a glance. The rich Yellow Pages resources not only support intelligent interception and reminder, but also integrate various lifestyles such as express delivery, taxi taking and ticket booking, which is comfortable and convenient.

Of course, a powerful system not only needs to have rich content, but also needs to support personalized settings. MIUI supports various custom settings such as screen display effect, font, theme, etc.  

In addition, MIUI calendar supports personalized subscription, including vehicle number limit, lottery, exam calendar and other subscriptions; The voice assistant not only recognizes quickly and accurately, but also provides a variety of voice control; Another feature of MIUI is the integration of smart home. Xiaomi 4C has its own infrared transmitter. Gu supports the remote control of mobile phones with various devices.    

Of course, in addition to these practical functions, I still have MIUI More expectations: ① more screenshots are supported. At present, the volume is added with the power button to screenshots, and more convenient screenshots such as three finger screenshots are expected, which support the cutting and decoration of screenshots; ② Support more black screen gestures; ③ Further thin the memory occupied by the system.

|Charging is a little slow, good battery life

It is equipped with a fast charging power adapter supporting 5V 2A/9V 1.2A/12V 1A, and supports the fast charging technology of Quick Charge2.0. The battery capacity is 3080mAh. In the actual test, 60% of the phone's power can be fully charged in the first hour. In the first 85 minutes, the power basically increases by 1% per minute, while the last 25% of the charging speed decreases. The final full charge takes about 2 hours, and the charging speed is not too fast. Xiaomi 4C uses a 5-inch 1080P screen, which consumes less power than the large screen. Basically, it can be charged once a day and a half to two days for non heavy use.

|Photo quality: more realistic color restoration, support manual mode

  Xiaomi 4C is equipped with a 13 million pixel high quality image sensor and dual color temperature flash, and supports the PDAF phase focusing technology.

3. Sunny days: partially open HDR mode

4. Night view: Xiaomi 4C adopts a large aperture of f2.0, which supports optical anti shake and manual mode.

(▽ Creative photo painting, tripod with more than 30 yuan, manual ISO adjustment and slow door)

(▽ Automatic mode of indoor night view)

The color restoration of Xiaomi 4C photography is more realistic, and other performances are not outstanding, which can be described as standard, but it is enough for daily photography.

But unfortunately, the Xiaomi camera does not support electronic aperture and slower slow door, and the playing method is much less.
