In today's increasingly fierce smartphone competition, both international manufacturers and domestic brands are facing tremendous pressure. Even industry giants like Xiaomi are no exception. After early rapid development, Xiaomi's pace has gradually slowed down Under the siege of OPPO and Huawei, Xiaomi has been squeezed out of the top three domestic market shares. In this case, Xiaomi cannot let go of the middle, high and low-end markets. The new Hongmi 4X is their work focusing on low-end markets. As one of the smart phone series with the longest history in the thousand yuan mobile phone market, Hongmi naturally has no lack of attention. Although the new Hongmi 4X still focuses on the low-end market, this new 4X has brought us some different visual feelings. With a new design, it can even be called the most beautiful Hongmi mobile phone in history without exaggeration.
Appearance and unpacking
The Hongmi 4X does not use the traditional style of the Hongmi series. It has boldly innovated its design style. Although it can be clearly found that it is a Xiaomi mobile phone from the three Diamond keys of Android, the appearance of the whole machine is still quite amazing at the moment of starting.
The overall design style is relatively mellow. In addition to the small body size, the first feeling when you get started is mellow and delicate. It is like holding a pebble full of years, which is like a Palm WebOS mobile phone.
In addition to the large arc design of the four corners and the back of the fuselage, it also uses 2.5D glass, which also makes it full of roundness.
The back is a three-stage design, the top and bottom are made of frosted plastic material, and the middle is made of metal sand blasting. However, both the similarity of hand feel and the transition treatment of gaps are good.
Fingerprint identification still adopts the rear type. Although it is relatively high, the body is very small, so the control is very convenient.
The back design is very simple, and there is nothing else except the Xiaomi logo. The back cover is made of matte black paint, which has a delicate feel. Although fingerprints may remain, it is much better than the glass body model, and it is easy to clean.
The rear camera adopts a 13 million pixel sensor, supports PDAF phase focusing, and has a five piece lens with an aperture of f/2.0.
It is equipped with a 5-inch LCD display with a resolution of 720P, and the official nominal maximum brightness is 450 nits. Although the resolution is not high, due to the small size of the screen, the fineness is OK, and the appearance is good.
The size of the fuselage is only 139.24 * 69.96 * 8.65mm. The compact fuselage has a good grip.
The three physical touch buttons have been retained, which has become one of the iconic appearance features of Xiaomi. Of course, as Xiaomi's new machine moves more fingerprint recognition to the front panel, this design may gradually disappear in the future.
The key layout continues the consistent design style of the Red Rice series. The power button and volume button are located on the right side of the body, and the SIM card slot is located on the left side of the body. It supports dual SIM cards or single SIM card+TF card. The 3.5mm headphone connector, infrared and noise reducing microphone are located on the top of the body.
At the bottom of the fuselage are still Micro USB connectors, speaker openings and call microphones. The whole body has a black matte surface, and the frame is no exception. The slightly shiny matte black paint is pretty cool.
On the whole, the appearance design of the Red Rice 4X can be regarded as quite excellent. 2.5D glass+cobblestone like sleek body+matte black back cover, there is not much to be picky about either in feel or design, and the materials and workmanship can also afford the price of its 699/899.
Performance and system experience
Processor performance
In terms of processor performance, it uses the Snapdragon 435 processor, with a single core score of about 650, which is basically at the same level as the Snapdragon 425 processor. The score of multi-core is about 2000, slightly higher than that of Snapdragon 425 and lower than that of MediaTek MT6753. The processor performance is basically at the same level as that of Hongmi 4 standard version.
Graphics Performance
In terms of graphics performance, the Snapdragon 435 is equipped with an Adreno 505 graphics processor, whose GFX score is basically at the same level as the MT6753 of MediaTek, slightly ahead of the Hongmi 3 which uses the Snapdragon 616 (Adreno 405 graphics processor) processor.
Storage performance
In terms of storage performance, its performance is at the same level as that of Hongmi 4 and Hongmi 4A in terms of both writing and reading. The three are higher than Meilan 5s and U20 in terms of continuous reading and random reading speed, but slightly lower than Meilan in terms of continuous writing and random writing. On the whole, the performance of the Hongmi 4X is at the same level as that of the models at the same price. It has little change from its predecessor Hongmi 3 and Hongmi 4, only showing a small improvement in performance.
In terms of system experience, the model we got is equipped with MIUI 8.7 development version, which is developed based on Android 6.0.1. The overall use experience is basically the same as that of other Xiaomi models. The overall UI of the system has the characteristics of Xiaomi. This design has been used for many years. Localization can also be criticized. However, after using so many Xiaomi devices, I think MIUI is a little bit lacking in novelty. In addition, the Snapdragon 435 used by the machine is slightly frame dropped in terms of performance. In most use scenarios, it is relatively smooth, but in some large applications or scenarios that require more system resources, there will be slight frame drop. However, the overall use experience is affordable.
Screen performance
In terms of screen, Hongmi 4X uses a 5-inch LCD screen with a resolution of 720P. Although the resolution is not high, the screen size is small, so there is no obvious graininess. It is acceptable to use. In terms of color standard, the average DeltaE of 108 colors is 3.6, and the highest DeltaE is only 8. The performance of the model at this price is relatively excellent. Under the default display effect, its color temperature is 7362, slightly cold. In terms of color gamut, it has 91.9% of sRGB color gamut, which is average. The highest brightness is 464.53 nits, higher than the nominal 450 nits, and the contrast is 1:1029, which is normal.
Photo effect
In terms of photographing, the rear camera of the camera uses a 13 million pixel sensor, supports phase focusing, uses a five piece lens set, has an aperture of f/2.0, and is equipped with monochrome flash. Let's see whether the camera of the camera has improved compared with the previous generation.

In terms of white balance, the performance of Hongmi 4X is relatively close to the truth, while the high configuration version of Hongmi 4 is obviously red on the whole. In terms of details, both are 13 million pixels, so the performance is quite similar.

The performance of Hongmi 4X in this group of proofs is also better. It is better in terms of exposure, details, and the sharpening of Hairui font edges. The font is easier to recognize after 100% magnification. In addition to the white balance, the high configuration version of Hongmi 4 is still biased towards infrared. The main problem is that the exposure is obviously insufficient. On the indoor scene on the right side of the screen, Hongmi 4X can also clearly distinguish objects such as stairs, doors and windows, but the high configuration version of Hongmi 4 is black in this part.

In terms of white balance, the red color of the high configuration version of Red Rice 4 remains the same, and the sky is slightly red. The performance in details is still basically the same, and the details of the leaves at the bottom of the left side are also similar. However, like the tree part in the dark at the bottom right, the high configuration of Hongmi 4 has again encountered the problem of insufficient exposure. The crown still visible in the sample of Hongmi 4X has completely disappeared under the camera of the high configuration of Hongmi 4.

In this group of sunset photos, the white balance of the two is not much different, and the ultimate discrimination after 100% magnification is also close. However, in terms of exposure, the high configuration of Hongmi 4 is still insufficient. In the lake and the scenery around the lake, the brightness is obviously insufficient, so many details are lost. Although in terms of parameters, the Hongmi 4X and the Hongmi 4 high configuration version are almost identical, in the daytime sample, the Hongmi 4X has improved significantly compared with the previous generation of products.
Night proof sheet

In terms of the night proof, the exposure of Red Rice 4X is fuller, the picture brightness is better, and the details are clearer, but the corresponding noise is also more. In the sky and other solid parts, the smearing is not too clean, and the noise and smearing traces can be clearly seen even without magnification. In contrast, the high configuration version of Hongmi 4 with low image brightness is better at noise control, but the painting is not clean enough, and the details are slightly inferior to that of Hongmi 4X.

In the scene of testing the discrimination at night, both of them can clearly distinguish the font on the billboard. In terms of font clarity and edge sharpness, this time, the high configuration version of Hongmi 4 is better, with sharper font and purer picture. However, the problem of insufficient exposure still exists, and the signboard in the park above the billboard disappears in the dark, Red rice 4X can see part of it.

The problems exposed in this group of scenes are basically similar to those in the previous two pictures. Although the Red Rice 4X has better picture brightness, the picture is not pure enough, with heavy noise and smearing marks. Although it can bring more picture details, the overall appearance is actually inferior to that of Red Rice 4.

In this group of samples, the more fully exposed version is the Hongmi 4 high configuration version, which is also a rare example of several groups of night scene samples. The Hongmi 4 high configuration version is better than the Hongmi 4X, but its white balance is slightly blue. In the dark part of Yuta, the high configuration version of Hongmi 4 also has more details. On the whole, in the night scene samples, Hongmi 4X and Hongmi 4 high configuration version have their own advantages and disadvantages. In terms of exposure, Hongmi 4X controls better and the picture brightness is also better, but in terms of noise control and smearing algorithm, it is inferior to Hongmi 4 high configuration version. The image purity and sharpness are also better than Hongmi 4 high configuration version.
Endurance&Charging&Heating
In addition to its beautiful appearance, it is not a red rice. It also continues one of the characteristics of the red rice family - super long endurance. It has a 4100mAh lithium-ion battery. Considering that it is equipped with a 720P resolution screen, it also has a rather exaggerated theoretical endurance, with a maximum of 36 hours of talk time, 4G standby can even last for 18 days. Let's take a look at its cognitive endurance performance.
After our three hour high-intensity endurance test, its remaining power is still 81%, which is still outstanding, maintaining the excellent endurance performance of the Hongmi series models. It is also among the top of the Xiaomi family of mobile phones. It is also one of the best models in the current market of all smart phones.
In terms of charging, its charging power is about 10W. Although its Snapdragon 435 theoretically supports the QC3.0 charging standard, it may be due to cost control. After all, the Hongmi 4X is only a 1000 yuan machine, and the models supporting fast charging at this price are rare.
In terms of heating, after about half an hour of the game, the maximum temperature of the front is 42.2 degrees Celsius, and the maximum temperature of the back is 40.6 degrees Celsius. The heating part is located in the upper middle of the fuselage, and the heating control is within a reasonable range.
summary
As the latest work of Red Rice, Red Rice 4X has the best appearance in the history of Red Rice. From the perspective of all the current Xiaomi models, there are only a few that can match the appearance of Red Rice 4X. Since Red Rice 4X has proved to everyone that Xiaomi can also look good, why not promote this design style to all the models?
In addition to the praiseworthy design style, its workmanship is also not inferior. Although it is a thousand yuan machine, its workmanship is really nothing to be picky about. Although the plastic materials on the top and bottom slightly reveal its identity as a thousand yuan machine. In addition to the plastic part of the fuselage, its vibration module performance can also make you feel uncomfortable, and the resonance of the fuselage is somewhat obvious. However, considering its price is only 699/899, it seems that this is not a problem. In terms of configuration, it uses Qualcomm Snapdragon 435 processor, combined with 2GB/3GB RAM+16GB/32GB ROM, which is standard. Although the processor has slightly improved, its performance is basically similar to that of Red Rice 4 from the perspective of various scores and specific use experience. The main difference is that it has a more beautiful shell. Of course, the shell replacement is quite successful, The Hongmi 4X is also the most beautiful Hongmi model.
