The most popular models of Xiaomi recently are Xiaomi Note2 and the concept mobile phone MIX, which are endorsed by Liang Chaowei. But don't forget the previous Gemini Xiaomi 5s/5s Plus. Xiaomi has launched four flagship manufacturers in the second half of the year. In the short term, it may be difficult for Xiaomi Note2 and MIX to start due to the output problem. If Xiaomi 5s/5s Plus is considered, please pay attention to the following points in the detailed evaluation of Xiaomi 5s.
3D metal is not so beautiful
At the press conference, President Lei said that Xiaomi 5s inherited the design concept of 3D glass/ceramics from Xiaomi 5 and adopted the concept of 3D metal. However, due to the addition of ultrasonic fingerprint and the inevitable nano injection antenna behind it, Xiaomi 5s is not similar to Xiaomi 5 at first glance, which makes people feel far apart.
The biggest difference on the front is the Home key. The Xiaomi 5s with ultrasonic fingerprint identification does not have any physical keys. The glass is hollowed out only at the Home key position, and is different from the Xiaomi 5 with plain glass. The glass edge of the Xiaomi 5s has a transitional arc. The feel of this Home key is "special" and needs to be adapted. Fingerprint recognition can only be said to be of medium level. After all, it is the first time to use ultrasonic fingerprint recognition. I hope this can be strengthened in future updates.
At the same time, the front logo of Xiaomi has also been cancelled, which greatly enhances the integrity of the front face of Xiaomi 5s. From the perspective of the front face, the appearance of Xiaomi 5s is better than that of Xiaomi 5. From the details of the earpiece and camera, it can be seen that the two machines are of the same origin.
The layout of both sides is completely consistent. Compared with Xiaomi 5, the Xiaomi 5s has a better feel due to the overall metal wrapping on the back, but the CNC chamfering and trimming angle connected to the screen is larger than that of Xiaomi 5, which makes it easier to handle.
There are more differences between the top and bottom, and the layout is consistent. It is a pity that Xiaomi 5s cancels the infrared function, which is more advantageous. The holes at the bottom are for aesthetic purposes, and also only have single speakers.
The positions of the camera and the flash are just interchangeable. Xiaomi 5s has inserted an IMX378 in this thickness, which is not outstanding. It is worth praising. The biggest problem caused by the 3D metal back is that the face value is lower than that of Xiaomi 5, in exchange for better wrapping and feel, and the back does not have the low low feeling of Red Rice Pro.
Unchanged screen
Although it is an upgraded version, the screen parameters of Xiaomi 5s and Xiaomi 5 are completely the same. The 5.15-inch 1080P screen has a maximum brightness of 600 nits, the measured brightness is 567 nits, the minimum brightness is less than 1 nit, and the color gamut covers 99.9% of sRGB.
The default color temperature of Xiaomi 5s is about 7400K. The 104 color standard test shows that the average DeltaE is 3.6 and the maximum DeltaE is 6.5. This performance is the same as that of Xiaomi 5. There is no screen upgrade.
The endurance version 821 is not weak
The biggest internal change of Xiaomi 5s is the replacement of the latest Qualcomm Snapdragon 821. However, the main frequency is slightly lower than the standard version 821. The maximum main frequency is 2.15GHz, and the GPU is 624MHz. The official explanation of Xiaomi is that the endurance version or performance version 821 is carried on different models according to different needs. I believe everyone is very concerned about the difference between the two. In GeekBench's test, the performance of Xiaomi 5s is no inferior to the performance version of 5s Plus.
In the GPU test, Xiaomi 5 is a bit ahead of the two "big brothers", which is surprising. However, the scores of Xiaomi 5s/5s Plus equipped with Snapdragon 821 are not very different. Although the main frequency reduction has caused a certain impact, the performance of Xiaomi 5s is not weak, and it can absolutely meet all the needs of daily use.
"Constant" MIUI
Compared with the hardware upgrade, the software part seems to be a little behind. Before the deadline, the latest version of MIUI 8 of Xiaomi 5s was 6.11.16, based on Android 6.0. The operation logic and interface are quite familiar to everyone, without any novelty. The functions are large and comprehensive, and after many netizens' complaints, the built-in advertisements are much less. In terms of fluency, even though Snapdragon 821 has extraordinary "power of flood", the difference between daily use and Xiaomi 5 is really hard to feel. We can only hope that MIUI 9, which is ready for internal testing, will bring us any surprises.
Xiaomi 5s 4G+128G high configuration version is equipped with pressure sensitive screen technology, which is similar to iPhone 3D Touch. However, compared with Apple's popularity in apps, Xiaomi's pressure sensitive screen can only be used in some built-in apps, and there are fewer menus to choose from. Xiaomi still has a long way to go to adapt to many apps. The actual experience is worse than that of the iPhone. The triggering force is more demanding, and the feedback from the system is not obvious. At the same time, Android 7.0 has added the function of long press to call out small menus. How Xiaomi makes good use of the pressure sensitive screen when updating the system in the future is a key point, otherwise it is just a selling point as a vase.
Shocking photos
Xiaomi 5s has made another major upgrade in the camera part: the CMOS is replaced with IMX378, which is called the super sensitive camera. We have seen its strength on Google's own son Nexus 5X/6P. The photographing interface and functions have not changed significantly. The photographing experience is good, and the focusing and imaging speed are satisfactory. Especially, the photographing experience at night is almost the same as that at daytime, which is excellent.
Due to the larger unit pixel area, Xiaomi 5s daytime sample has more light input than Xiaomi 5, the overall picture brightness is closer to the real situation, the white balance and noise control are better than Xiaomi 5, and the picture appearance is better.
Zoom in to 100%. Due to the higher pixel advantage of Xiaomi 5, its analytical power is slightly better than that of Xiaomi 5s. However, the obvious noise and the darker picture brightness make people think that Xiaomi 5s is more excellent.
In this group of evening samples, Xiaomi 5s is more exquisite in the restoration of light, which well expresses the environmental atmosphere at that time, and the dark details are also more excellent. In contrast, Xiaomi 5s is not satisfactory.
When shooting at night, the gap between Xiaomi 5s and Xiaomi 5 is visible to the naked eye. Glare control, white balance, and light and shade details can be said that Xiaomi 5s has left Xiaomi 5 far behind, and there is no lag in the focusing process. Xiaomi 5 occasionally fails to focus. If you really want to find fault, Xiaomi's 5s screen brightness is really high (laugh).
Compared with the previous generation of Xiaomi 5, it has improved. Can it be at the same level as other flagship products? Compared with the iPhone 7, the iPhone 7 is blue and the Xiaomi 5s is red in this group of samples. The white balance of the iPhone 7 is closer to the actual scene, and the discrimination is almost the same. The noise control is good for both. Xiaomi 5s even captured the scenery outside the glass window.
In these two sets of samples, the iPhone 7 is closer to the real scene, and the color saturation of Xiaomi 5s is higher, which makes the Xiaomi 5s sample more eye-catching. When the color is rich, the appearance of Xiaomi 5s sample is better.
In the night sample, Xiaomi 5s has better anti glare ability than the iPhone, but the edge imaging is not as good as the iPhone. The details and tolerance of the central part are very similar, and the white balance performance is excellent.
In this group of samples, the imaging of Xiaomi 5s is obviously better than that of iPhone 7, and the discrimination, anti glare, and details of light and dark parts are all successful. To say the least, the color saturation of Xiaomi 5s is slightly higher, and the red part of the signboard is too bright.
In other weak light environments, Xiaomi 5s may not play so well. In this group of samples, iPhone 7 has better discrimination than Xiaomi 5s, and its overall performance is better. I feel that Xiaomi 5s has a hard time in this environment.
In general, the photo of Xiaomi 5s made the author a little overjoyed. Even though the expected performance of Xiaomi 5s would not be too bad due to the advantages of hardware, it felt really good in actual use. The white balance of Xiaomi's mobile phone is not easy to drift in the past, and the noise control of night samples is also quite good. The overall photography experience is comfortable, which can be said that Xiaomi is not "Xiaomi" in terms of photography.
Normal endurance
Xiaomi 5s also improves the battery to 3200mAh, which is 200mAh more than Xiaomi 5. However, in the classic 3-hour endurance test, the final remaining 74% of Xiaomi 5s is lower than the 77% of Xiaomi 5. This is a standard level in flagship mobile phones, not as tough as the 5s Plus in the same period. By careful comparison with Xiaomi 5, we can see that Xiaomi 5s consumes more power in games and 4G Internet access, which may be related to the current firmware. System updates should be able to achieve the same level as Xiaomi 5.
Due to the metal back, after playing and taking photos for a long time, it will feel warm. In addition to Xiaomi's active scheduling, the Snapdragon 821's fever is still considerable, but not hot.
Is it worth buying?
As one of the four flagship brands of Xiaomi in the second half of the year, should Xiaomi 5s start? It has the highest photo taking level among Xiaomi mobile phones so far, a flawless Snapdragon 821, a decent screen and a long life. If it is not good enough, only the 3D metal back is slightly ugly, but the dark gray is acceptable. As long as it is not a customer whose appearance is paramount and whose requirements for long life are not harsh, Xiaomi 5s is worth considering. In a word: Xiaomi 5s is probably the most practical mobile phone of Xiaomi in 2016.
