Xiaomi Mobile 4C is an upgraded version of Xiaomi Mobile 4i, the first overseas model of Xiaomi, which was released on September 22, 2015 and is known as the "little prince of Android". The Xiaomi mobile phone 4C adopts a 5-inch 1080p screen, is equipped with Snapdragon 808 six core processor, has two versions of 2GB RAM/16GB ROM and 3GB RAM/32GB ROM, is equipped with a 500W pixel front camera and a 1300W pixel rear camera, supports All Netcom 2.0, and runs the Android 5.5de MIUI 7 system. The biggest change of Xiaomi 4C compared with Xiaomi 4i is that the processor is upgraded to a more powerful Snapdragon 808 processor, which is also more powerful than the Snapdragon 801 installed in Xiaomi 4 and Xiaomi Note Standard. The above information is official data. What's the real performance and experience of this mobile phone? Let's go to details.

[Unpacking]

Xiaomi's mobile phone 4C is packed in orange with a new design. Compared with the kraft paper packaging that Xiaomi has always used, the orange packaging box is more youthful and energetic. This may be Xiaomi's positioning for Xiaomi's 4C.

The overall design of the packaging box still follows the classic design in the past, but only the color changes. There is a label on the bottom of the back of the packaging box, on which are some information about the model, configuration, color and manufacturer of Xiaomi mobile phone 4C. Among them, "All Netcom version | Dual card and Dual standby" is very conspicuous.

After opening the box cover, we can see the main body of the Xiaomi 4C mobile phone. The front of the mobile phone uses a black panel, and the back cover is available in five colors: white, gray, blue, pink and yellow. This one in my hand is white.

After taking out the Xiaomi mobile phone 4C on the upper layer, neatly place the charging plug, charging line, card taking pin, warranty card and instructions on the bottom of the packaging box, which are the same as the accessories in the previous Xiaomi mobile phone packaging box.

Xiaomi's 4C phone is equipped with a 5V2A/9V2A/12V1A smart charging plug. The charging cable is a USB charging cable of Type-C socket. From a close look, we can see that the USB charging cable of Xiaomi's Type-C socket is different from Apple's, but there is no difference in daily use.

[Appearance appreciation]

The front of Xiaomi mobile phone 4C is equipped with a 5-inch 1080p full HD sunlight screen, which can clearly see the screen content in strong sunlight. In addition, it also supports luminous screen, eye protection mode, color temperature adjustment and dynamic frame rate adjustment.

The screen and case of Xiaomi mobile phone 4C are not in direct contact. There is a ring of plastic partition between them, so that when the side of the mobile phone falls, it can play a buffer role and protect the glass on the surface of the mobile phone.

Xiaomi mobile phone 4C has a body size of 138.1mm * 69.6mm * 7.8mm and a weight of 128g. Compared with Xiaomi 4, it is thinner, lighter, comfortable and easy to operate with one hand.

The upper left corner of the front screen of the phone is the "MI" logo, and the earpiece is placed in the middle of the top of the screen. The left side of the earpiece is the sensor, the right side is the front camera, and there is a hidden LED indicator on the right side of the front camera. It will only light up when charging or there is a message reminder.

At the bottom of the front screen of the phone are three virtual keys, which are menu key, HOME key and return key from left to right. The keys are equipped with white backlight. Long press the HOME key to enter the recent task management interface.

On the top of the phone, there is a 3.5mm headphone jack, and there is an infrared emission hole beside the headphone jack. Through the built-in Xiaomi universal remote control application, you can control most of the electrical equipment in the home, and the phone will become a universal remote control immediately.

In the middle of the bottom of the phone is a Type-C interface, which is also the first time that Type-C interface appears on Xiaomi mobile phones. Since then, we don't worry about the pros and cons of the data cable. It is very convenient to use. Next to the interface is the main microphone hole of the phone.

The Xiaomi mobile phone 4C adopts a fully enclosed body shell design. Although it still uses plastic materials, the body uses a matte coating texture, and the surface uses a specially developed anti oil spray formula. The biggest advantage is that it is not easy to stain fingerprints, and it is also very comfortable to feel.

On the top left of the back of the phone is the 1300W pixel rear camera of the phone, which uses PDAF phase focusing to focus as fast as 0.1 seconds, and the camera is flush with the back cover. There is a metal band around the camera, which can play a protective role. On the left side of the camera are two LED dual color temperature flash lights, and on the right side are noise reduction microphone holes. The three are strictly aligned in the middle, which looks really neat.

There is a silver "MI" logo at the bottom of the middle of the back, and 114 voice cavity holes made by CNC drilling process are arranged in three rows, and there is a small fulcrum more than 1mm below the voice cavity. However, when the phone is square, the volume will be affected. It is better to directly place the speaker at the bottom of the phone.

There is a phone SIM slot above the left border of the phone, which supports the dual SIM and dual standby of all Netcom. Both the SIM1 slot and the SIM2 slot can only place Micro SIM, and do not support SD card expansion. This is a bit wasteful for mobile phone users with a single card, and the design is slightly inhumane.

On the right side of the phone frame are the volume key and power key. The volume up and down buttons are all metal, and the damping of the buttons is hard. Below the volume key is a power key, which is also made of metal, and the edge has also been polished.

[MIUI 7 Experience]

Xiaomi Mobile 4C runs the latest MIUI 7.2 stable system designed based on Android 5.1. As one of the best customized Android UIs in China at present, the MIUI system is deeply loved by the majority of users. Many users who like Xiaomi Mobile actually come here to experience the MIUI system. MIUI 7 system is designed to be fast, power saving and for you. Let me take you to have a detailed understanding.

First of all, let's briefly understand the interface and icons of the MIUI system. Entering the main page of the system will give you a very simple feeling. The application icons are flat design, and the third-party application icons have also been optimized, making the overall appearance more unified. In the system lock screen interface, slide up to unlock, slide left to quickly enter the camera interface, and slide right to enter the millet control center.

The dialing interface of Xiaomi's 4C mobile phone is also very simple, and a practical yellow page function is integrated here. After entering the "yellow page" interface, we can experience many convenient services here, which is very convenient to use. I prefer this function.

In any interface of the system, slide down from the top of the screen to enter the notification interface, where we can view the notifications of the system and applications, and slide left in the notification interface to enter the shortcut switch interface, where some common shortcut tools in our daily life are integrated.

MIUI system also supports music player and video player, and supports not only local play, but also online play function. The music player also supports functions such as listening to music and recognizing music, sleeping mode and online download, and has rich music resources; The online resources in the video player are also rich, and the update speed is also fast. With the backing of the video league built by Xiaomi last year with 1 billion dollars, the video content should not be worried.

One of the reasons why people like MIUI system is that I think it has something to do with its rich theme resources. In MIUI 7 system, four sets of theme UI are officially built in, which can meet the individual needs of different people. The system has built-in personalized themes, app stores and game centers, so we can directly change themes, download apps and games, avoiding the trouble of looking everywhere. There are tens of thousands of themes and wallpaper resources in the personalized theme, which can meet everyone's different needs, and support the mashup operation. You can DIY your own mobile phone theme.

The system also has a built-in "security center" function, where we can perform 7 functions, including mobile phone physical examination, garbage cleaning, network assistant, harassment interception, power saving optimization, virus scanning and authorization management. The functions are relatively comprehensive, and there is no need to download third-party mobile phone management applications.

Finally, let's take a look at the mobile phone setting interface in MIUI 7. The overall design of the setting interface is simple, and the setting options are simply divided. Different types of setting options are marked by icons in different colors, and the middle is divided by dividing lines. In the "About Mobile Phone" interface, we can have a simple understanding of mobile phone configuration.

[Features]

『 One button switch 』

Xiaomi 4C mobile phone is equipped with a new MIUI 7.2 system, in which several new functions are added. One of the unique features is the "one touch switch", which supports small mobile phones and various mainstream Android models. New and old mobile phones are interconnected. Without networking and traffic, data such as contacts, photos, applications, music and videos can be transferred by one touch as needed, and even the layout of desktop apps can be "completely copied." This function is relatively practical.

『 Screen Lock Pictorial 』

Lock screen pictorial is also a feature function in MIUI. After entering the lock screen interface, click the icon in the upper right corner to enter the lock screen pictorial interface. You can set the poster style according to your preferences, and can also collect and share posters.

Document Management

The file management interface in the new version of MIUI 7 has also been redesigned and optimized. In the file manager, we can view the files in the phone by category, source or time, and can also directly search and clean with one button. There is also a special "recent" interface, where you can view the file operations according to time. There is also a "quick transfer" option at the bottom of the interface, which allows you to share pictures, videos and documents to multiple friends with zero traffic. You can quickly complete the file transfer operation without networking.

Private Folder

In the "File Management" interface of the system, there is also a "private folder" function hidden. We can encrypt important files, make them invisible from the phone, so that others cannot find them. Pull down in the "File Management" interface to enter the "Private Folder" interface. Click the icon in the upper right corner to add a file. You need to set a password before you can use it for the first time.

『 Large font 』

Xiaomi MIUI7 has added two new font sizes, Super Large and Big Mac, and each font has specially designed all the interfaces. The Big Mac font is not only large enough, but also the interface looks more elegant. You can set it through the "font size" option in the "setting" interface. The actual experience is very good, and it is more suitable for the elderly.

Children Mode

There is also a special "children mode" in the system, which is an interactive interface designed for children. After switching to this mode, children can only access some specified applications, and can not do any other operations. This can prevent problems such as mobile phone deduction, and also protect personal information and desktop layout in our mobile phones. After the actual test, after switching to this mode, you must enter a password to exit. It really works.

Xiaomi Roaming

Xiaomi Roaming is designed to prevent overseas roaming traffic from sneaking away. When the system detects a situation, it will automatically enter the roaming mode and turn off the data network. In addition, it also provides data roaming services in 36 countries and regions. You can directly purchase traffic without changing the SIM card. The traffic cost is also very cheap. This function is suitable for people who often go abroad, But I didn't have the chance to have a practical experience.

『 Edge touch 』

At present, this "edge touch" is a special feature exclusive to Xiaomi 4C. It extends the mobile phone's operable area from the screen to both sides of the phone's border. Currently, it only supports global return and photo taking. However, after the "Edge Touch" mode is enabled, especially after the "Global Return" function is enabled, even if you do not double-click the edge of the phone in the actual use of the phone, the return phenomenon will often occur. It seems that this still needs to be optimized.

[In depth experience]

"Performance score"

Although it is no longer the time to compete for points, running points can still reflect the performance of a mobile phone to a certain extent. The following two running points software, the latest version of Anthare and Master Lu, were selected to test the Xiaomi mobile phone 4C. Anthare scored 41691 points and Master Lu scored 34443 points, which should be in the middle level, However, it is enough for daily use.

『 Graphic processing test 』

Next, we will continue to test the performance of the mobile phone through some professional test software. NenaMark2 is a hardware accelerated benchmark test program for Android devices. It tests the graphics ability of the mobile phone by demonstrating a real-time rendered image, including reflection, dynamic shadow, surface parameters, complex light modes, etc. The test result of NenaMark2 is 60.0fps. From this score, we can see that the mobile phone's graphics processing ability is good.

『 Browser performance test 』

The browser of the MIUI system is also tested briefly. Vellamo is a benchmark application developed by Qualcomm. It can measure the performance and stability of the machine browser, including Java script performance, rendering, networking, and user interface. The higher the score, the better the performance of the browser provided by the system and the better the web browsing experience. From the score, the browser provided by the system is good. For users who like the MIUI system, the browser is easy to use. If you don't like it, you can download a third-party browser to use.

『 Signal test 』

Xiaomi Mobile 4C adopts All Netcom 2.0, which upgrades basic communication functions, supports high-speed rail mode and intelligent roaming mode, and adopts dual band and dual antenna design. What's the effect of mobile phone signal reception? Let's test the signal strength of mobile phone through software. It can be seen from the test that the reception strength of wifi signals has indeed increased. The indoor 4G signal is between - 97dBm and - 98dBm, and the outdoor 4G signal is between - 71dBm and - 81dBm. In general, the reception of signals has improved. There has been no disconnection and unclear calls in the use of these days.

Game Experience

In fact, mobile phone games can be tested from one side. However, most mobile phone hardware configurations are in surplus at present, and some large-scale 3D mobile phone games can be easily controlled even if they are thousands of yuan. Xiaomi's mobile phone 4C is equipped with Snapdragon 808 processor and Adreno 418 graphics processor, which greatly accelerates the game. Here, two large-scale mobile games, Real Racing 3 and NBA2K16, are selected for a simple experience. First of all, I did a simple test on the real car 3. After 20 minutes of the game, the whole process of the game was very smooth, the picture was very clear, there was no jam, and the scene and raised dust were also very real.

Then we had a 20 minute experience of the "NBA2K16" game. The whole running process of the game was smooth, and the direction control was also very fast. During this period, there was no stuck phenomenon, so it could keep running smoothly. Moreover, the picture effect of the game was also very good. When we switched to the close shot, even the expressions of the characters could be clearly seen.

『 Power consumption test 』

In our daily use of mobile phones, playing games and watching videos should be the two items that consume the most power. The following is a simple test of the power consumption of playing videos on mobile phones. Using the default player provided by MIUI, the sound and brightness are all adjusted to 50%, and full screen play. After one hour of continuous movie play, the power consumption of mobile phones will be from 50% to 32%, and the power consumption will be 18%, If you are a heavy player, it is inevitable to charge once a day or even several times a day.

『 Charging test 』

Xiaomi mobile phone 4C uses a 5V2A/9V2A/12V1A smart charging plug, but does not support fast charging. The charging efficiency was simply tested. The original charging plug and charging line were used for charging test. When the mobile phone was powered off automatically, after 10 minutes of charging, the charging power was 11%, and it took 48 minutes to charge 50%. After 124 minutes, the mobile phone was charged. The charging speed was still far from the current fast charging speed.

[Camera test]

The Xiaomi mobile phone 4C is equipped with a 1300W pixel high quality image sensor, PDAF phase focusing technology, focusing as fast as 0.1 seconds, and a new generation of Qualcomm ISP image processor. It has dark light image quality enhancement technology and pixel level dynamic range adjustment technology to help you get photos with clear image quality and less noise. The shooting interface of the MIUI camera is very simple. At the lower left of the interface is the album option, in the middle is the shooting button, and on the right is the photography option. The camera supports 9 shooting modes, including panorama, countdown, voice shutter, manual, level, beauty, night scene shake proof, axis shift photography and fish eye lens. It also has its own camera filter, with 4 options, including beauty, photography, small video and video recording. The function is very powerful. In the shooting interface, slide left to enter the "shooting mode" interface, and slide right to enter the "camera filter" interface. The operation is very simple.

Automatic sample

Since my photography level is limited, here are some photos taken at random. In fact, most users use mobile phone cameras mainly in automatic mode. The above photos are taken in automatic mode of the camera, only for size modification. The sample of Xiaomi mobile phone 4C has good definition, slightly high saturation, and the overall color is bright.

"Macro proof sheet"

The rear camera of Xiaomi mobile phone 4C is 1300W pixels and F2.0 aperture. The addition of a large aperture can make the background appear blurred when shooting macro. If you want to take a better sample of the illusion effect, you still need to use manual focusing to shoot.

Other samples

Xiaomi Mobile 4C also supports two interesting shooting modes, "fisheye lens" and "axis shifting photography", which can take very special photo samples. Above the two samples are "fisheye lens" samples, and below them are "axis shifting photography" samples.

Finally, a simple test was carried out on the night shooting effect of the mobile phone. Night scene shooting has always been the pain point of the mobile phone camera. Although the Xiaomi mobile phone 4C uses Qualcomm's latest ISP image processor, which can solve the problem of blurring and noise in dark light shooting details, it can be seen from the sample photos that noise still exists, but the details do seem to have improved.

Summary

After this period of experience, the overall feeling of Xiaomi's mobile phone 4C is still very good, and the MIUI 7 system is also very smooth. Recently, Xiaomi's official website also launched a price reduction promotion campaign, making it the cheapest Xiaolong 808 mobile phone so far, with high cost performance. Finally, according to the actual use experience of individuals, the advantages and disadvantages of this Xiaomi mobile phone 4C are briefly summarized.

advantage: Equipped with 64 bit Snapdragon 808 processor, high cost performance; The 5-inch screen is designed with a fully enclosed shell, which is comfortable to handle and suitable for single hand operation; It supports dual cards and dual standby, adopts All Netcom 2.0, and mobile, China Unicom and telecom cards can be matched at will; Xiaomi's first mobile phone equipped with Type-C two-sided charging interface is easy to use, with front and back inserted freely; Support the "edge touch" function to expand the mobile phone operation from the screen to the phone border; The rear 1300W pixel camera supports phase focusing and is equipped with a Qualcomm ISP image processor, which improves the picture quality; Equipped with the new MIUI 7.2 system, this is also the killer of Xiaomi mobile phones.

Shortcomings&Suggestions: The phone speaker is on the back of the phone. When the phone is flat, it will have a significant impact on the phone sound; Xiaomi mobile 4C supports the "edge touch" function. When the "global return" function is enabled, it will automatically return even if there is no double click in daily use, and still needs to continue to optimize; The night scene shooting of the camera still needs to be optimized, and the noise is obvious; It's a pity that the popular fingerprint recognition function is not equipped. Of course, if you like fingerprints, you can now choose Xiaomi 4S.
