Xiaomi Company held a media conference on September 22, and released three products: Xiaomi mobile phone 4c, Xiaomi pocket audio and Xiaomi mobile phone card. Xiaomi mobile phone 4c can be said to make people understand the cost performance of Xiaomi again. Let's take a look at what this "Android prince" can do:
Unpacking and appearance
Xiaomi mobile phone 4c has made a great change in packaging. It has been changed into a bright orange paper box, which is quite different from the previous style.
There are relevant hardware parameters on the back of the package. We got the high configuration version (priced at 1499 yuan), which uses 3G Ram+32G Rom. In other hardware aspects, the high configuration and low configuration are the same Snapdragon 808 six core 1.8GHz processor, 5-inch 1080P IPS screen, 3080mAh battery capacity, 13 megapixel rear camera , front 5 megapixel camera. In addition, the whole series of Xiaomi 4c mobile phones support the functions of All Netcom+dual card and dual standby, especially it can support Telecom+Mobile/Unicom use 4G to access the Internet at the same time 。
When opening the package, the phone is placed on the top as usual, and there is a frosted protective film on the screen surface.
The second layer of the package is related instructions and accessories. Although the contents are still the same, they are finally placed in a new way, which is a bit new.
The accessories in the package are very simple, including power adapter, data cable, clip and relevant instructions.
The clamping needle is placed under the instruction manual.
The Xiaomi mobile phone 4c is equipped with a USB Type-C interface that is still rare at present. Unlike the OnePlus, LeEco and other mobile phones, the data cable only supports two-sided insertion at the mobile phone end, while the standard USB interface section is no different from the general data cable.
A standard USB port can only have one direction plug.
It is worth mentioning that Xiaomi's official website is also retailing USB Type-C adapters, which cost 5 yuan each.
Xiaomi mobile phone 4c support Qualcomm Quick Charge 2.0 Technology Therefore, the power adapter is the same as the Xiaomi mobile phone 4 and the Xiaomi mobile phone Note, and supports the charging specification of 9V 1.2A.
The design style of the mobile phone is somewhat similar to that of the red rice Note2, but because the screen size is only 5 inches, the size is much smaller.
There are still some necessary information signs on the back and protective stickers on the lens.
Xiaomi mobile phone 4c also has "off screen aesthetics", which uses a full fit screen.
The dot matrix on the touch screen is obvious.
The earpiece adopts the groove design and is small in size. On the left side of the earpiece is the distance sensor and light sensor, on the right side is the 5 megapixel front camera, and on the far right is the LED signal light.
Continuing the style of previous products, the Xiaomi 4c still has three touch buttons. By default, it will emit a white backlight. The functions are multi task key, home key and return key. The functions of the buttons support customization.
The color saturation of Xiaomi mobile phone 4c is high, which is officially claimed to reach 95% NTSC color gamut (The parameters are the same as those of Xiaomi 4 produced in 2015). The high color gamut of the screen is also a continuation of Xiaomi 4, Xiaomi Note and other products.
There is a slight light leak at the top of the screen.
The rear cover adopts an integrated design. The rear cover is matte and has an anti oil coating. The speaker is also placed on the back of the body.
The camera part of Xiaomi mobile phone 4c adopts Sony IMX258 or Samsung S5K3M2 Sensor, the former is an improved version of IMX214, mainly adding Phase focusing , the latter supports Samsung ISOCELL technology , also supports phase focusing. In addition, Xiaomi mobile phone 4c also uses 5P lenses and dual color temperature fill light
On the right side of the fuselage are the volume key and power key.
The SIM card slot is on the left side of the fuselage, which can be easily opened with the attached card needle.
Supports two micro SIM cards Xiaomi named Xiaomi's mobile phone 4c "All Netcom 2.0", which allows the simultaneous insertion of a telecom card and a mobile/Unicom card, and both of them can support 4G networks.
There is a 3.5mm headphone connector on the top of the fuselage, and there is an infrared sensor that even Xiaomi Note does not have.
At the bottom are USB Type-C interface and call microphone.
system
The machine we got has been pre painted MIUI7 Development Edition , which is also the most complete in terms of functions, but the shipping version still uses MIUI6 , which is the same as that of Red Rice Note2. The system used by Xiaomi mobile phone 4c is based on the latest Android 5.1.1 Of.
We won't introduce MIUI7 any more. Let's take a look at some new features on Xiaomi mobile phone 4c.
The Xiaomi mobile phone 4c still supports the color temperature adjustment of the screen, but the adjustment has only three gears: warm color, natural color and cold color. The adjustment span is slightly large.
Xiaomi mobile phone 4c is equipped with an infrared sensor on the top of the body, which can let the mobile phone replace the remote control and is very convenient to use.
Double click wake-up can be said to be a function that rice noodles look forward to "looking forward to the stars and the moon". In fact, it is not difficult to realize this function, but it is said that Xiaomi made great efforts in power consumption to add this function.
The biggest innovative function of Xiaomi's 4c mobile phone can be said to be the edge touch technology. When we click or double-click the phone border, we can realize the return or shutter operation. The specific implementation method is In the global state, as long as we tap the phone border twice, we can realize the return function , which can basically replace the function of returning to the touch key. After entering the camera, we passed Click the frame to realize the shutter function 。
In the setting of edge touch, we can see the schematic diagram of the touch range, covering the left and right borders of the phone. At the same time, we can customize whether to enable the edge touch function.
performance
Xiaomi mobile phone 4c uses Qualcomm's top Snapdragon 808 processor Dual core Cortex-A57 1824MHz and quad core Cortex-A53 1440MHz Form a 64 bit six core architecture, 20nm process , graphics processor is Adreno 418, dual channel LPDDR3 933MHz, memory bandwidth 14.9GB/s (Same as Snapdragon 801 MSM8974AC). From the "book" point of view, it is much weaker than the Snapdragon 810. Of course, the heat and power consumption will not be so impressive. Snapdragon 808 is not widely used on mobile phones. Before that, there were LG G4 Moto X Style、 360 Qiku flagship, Samsung G9198 and other products. The Xiaomi 4c mobile phone uses this high-end SoC with 1080P, which can be said to be enough.
The graphics processor of Snapdragon 808 is Adreno 418 with 128 ALUs (Adreno 430 of Snapdragon 810 is 192), The frequency is 600MHz, and the performance is between Adreno 330 of Snapdragon 801 and Adreno 420 of Snapdragon 805 The Xiaomi 4c system is based on Android 5.1.1, GPU driver V103, and supports OpenGL ES 3.1.
In terms of running points, perhaps because the physical fitness of the mobile phone itself is not good enough, or the "posture" is not correct enough, the test machine on our hands can not reach the high score of nearly 58000 that was nominal at the press conference, but this score is quite good for Snapdragon 808.
In daily applications, six cores can be fully opened, and each core is at the highest frequency. When the CPU starts to overheat and reduce frequency for a period of time, one large core will be closed, and the other large core will also be reduced to a lower frequency.
We also use the recently popular "metaphysical curve" to see how smooth Xiaomi mobile phone 4c of Snapdragon 808+1080P is. It can be seen that both system UI and third-party applications have good performance.

millet The rear of the mobile phone 4c adopts Sony's new stack sensor IMX258 (IMX214 upgraded version, with PDAF phase focusing) and Samsung ISOCELL sensor S5K3M2 (also used on the red rice Note2, which also supports phase focusing), 13 million pixels, F2.0 aperture, which is mainstream in terms of configuration, while the IMX258 sensor is a new product that we have less contact with.
Since the system of Xiaomi 4c has blocked the cit mode of viewing hardware information, we can check the sensor condition of our Xiaomi 4c through the command. By this way, we can judge that this batch of Xiaomi 4c has used IMX258 Sensor.
In addition, we use the same way to view the screen panel, and we can see that our mobile phone is used SHARP The screen panel of LG, Youda and even Tianma is not used.
Back to the photo taking and photo taking interface, the Xiaomi 4c phone is not very different from the Xiaomi Note, which is still a familiar way of use. However, due to the introduction of edge touch, we can use the touch phone frame to press the "shutter" operation. In the picture, pay attention to the small white dot in the upper left corner of the camera, which is the location prompt of edge touch.
In addition, perhaps due to the product positioning, the Xiaomi 4c does not support 4K video capture, and the maximum support is 1080P.
Finally, let's take a look at the imaging comparison between Xiaomi mobile phone 4c and iPhone 6 Plus:

"All Netcom 2.0" and others
Xiaomi mobile phone 4c supports dual card and dual standby, and uses "All Netcom 2.0", that is After the telecom card is inserted, another mobile/Unicom card can still access 4G/3G Internet This function has never been seen before.
In addition, here is an introduction to the "Let Me Go" phone card of Xiaomi Mobile released at the same time with Xiaomi Mobile 4c. It uses the Unicom system (WCDMA and FDD-LTE), no monthly fee, 0.1 yuan/MB for Internet access, 0.1 yuan/minute for calls, and 0.1 yuan/message.
The SIM card of Xiaomi Mobile has two card holders, that is, all mobile phones use it without cutting the card.
Here, we insert Xiaomi Mobile's Renwoxing card into card 1, and insert China Telecom card into card 2. Card 1 can still access 4G Internet. At the same time, we can select which card is used for Internet access in the settings.
Summary
The Xiaomi 4c mobile phone is a "price butcher" for many mobile phone brands, especially for the SoC Xiaolong 808, which has raised the price of its mobile phone to 1299 yuan, highlighting the cost performance of the Xiaomi 4c mobile phone. As for the mobile phone itself, its excellent smoothness, support of All Netcom 2.0, edge touch and other functions are its selling points. The Xiaomi 4c mobile phone is really a good choice for users who have demand for performance and network, but also pursue cost performance. For more introduction and related tests of Xiaomi mobile phone 4c, please pay attention to our subsequent detailed evaluation.
