Why is the quality of Xiaomi 5 mobile phone so poor? I don't know if it's a common problem.
First, a strange fever
Because Qualcomm's 8 10 pothole is nicknamed "Burning Dragon 8 10" by many people, when Qualcomm launched the 820 this time, it also particularly emphasized the reduction of power consumption and calorific value-"the performance is improved by 40% compared with the previous generation, and the energy efficiency is improved by 40%". As one of the first models of 820, Xiaomi 5 was tested by many media for the first time, but the results were different, and some said a lot.
As far as my own use is concerned, Xiaomi 5 of Xiaolong 820 still has some fever problems, although it is not as serious as 8 10, which is embodied in the following points:
1, playing games has a fever. I often play large-scale games, such as Vanity and Real Racing. After running for a few minutes or so, I can feel the camera and the hands on the upper metal frame are hot, and they have also been measured by the thermometer at hand. (Room temperature is about 20 degrees) The maximum mobile phone is 43-44 degrees, and the lower body is 37-38 degrees, which is much better than my colleague's 8 10 mobile phone music MAX.
2. Heat when charging. This time, Xiaomi 5 uses QC3.0 for fast charging, and the charging time is only 1 hour. However, when charging, the whole body temperature rises rapidly, and it is the kind that the whole body is hot. When you hold it in your hand, you can obviously feel the heat and the temperature is measured. The whole body is about 39 degrees (room temperature 18 degrees). Although it will decrease after charging, it means that you can't play games while charging, and the charging and heating of the other OPPO R9 at hand is much better, and the body temperature has basically not changed;
Charging and heating
3. Unexplained fever. When I first used it, there was an inexplicable temperature rise. Later, the system reminded me to update 20 applications. I thought it was a pot for updating and installing applications, and I didn't take it to heart. But then there were several inexplicable fevers, all of which showed that there were no big programs (high-definition videos and games), only a few text apps such as WeChat and news in the background, only some system settings or a few photos, and then the temperature in the upper part of the fuselage suddenly soared. I haven't figured out why.
Second, extensive systematic advertising and notification.
More and more advertisements of MIUI 7 make many people vomit, but only when I actually use them do I know why so many people vomit-because it appears in too many places and with too high frequency, which has nothing to do with your operation. I won't say a comprehensive summary of the advertising sources. I will only mention the advertisements in my general system application:
The weather page can be closed here, and the content is still weather-related, which is acceptable:
The browser homepage is, er ... a bit dense, not as refreshing as the S6 browser I used before:
"Guess what you like" will appear when merging folders and opening folders. I guess you are a big head ghost. Be sure to uncheck it, otherwise it will pop up every time and I don't know where to close it:
The most annoying things are folder management and garbage cleaning, because they are frequently used system applications, and I don't know what they are. Why did you push a sports news when I was in cclean? !
Also, be sure to turn off the Xiaomi Life, Xiaomi Video, Xiaomi News and other notifications in the settings, otherwise your notification bar will become like this in a while:
Third, the screen is red.
First of all, Xiaomi 5 has a good screen look and feel. Officials say that the backlight module has several more LED lights, so the maximum brightness is also very high. Don't worry about not seeing clearly in the sun.
However, when the screen is slightly tilted, whether it is adjusted to enhanced mode or standard mode, it always feels red. A search on the Internet is said to be a common problem of IPS screens with wide color gamut. Many models such as mate8 were also popular before. At present, I feel that the color gamut is not wide, and this color cast is really not suitable for the time being. In contrast, I dug out an old Sony xl39h, which is also an IPS screen, and there is no red problem with the tilt angle.
Moreover, after changing from S6 to Xiaomi 5' s IPS screen, I feel the benefits of amoled screen: high contrast, pure black and prominent dark details, such as the following picture, underwater reflection, dark details S6 beat Xiaomi 5:
The pure black picture is more obvious. The dark part of the amoled screen is like turning it off. Although the minimum screen brightness of Xiaomi 5 has been well controlled, there will still be some light:
Now more and more mobile phones use amoled screens. It is said that iPhone7 also needs to change its A screen. In addition to being light and energy-saving, the contrast advantage brought by self-luminous pixels is too obvious.
Fourth, the knife cuts the hand.
This time, the screen glass of Xiaomi 5 unexpectedly reversed. It turned out that the 2.5D glass on Xiaomi note didn't take long. A flat plate on the front, together with the curved glass on the back, forms a half-moon shape.
The back feels so comfortable; On the front, because the screen is not 2.5D glass, there is no smooth transition in the frame, only narrow metal CNC corner cutting. People who are used to sliding on the edge of the screen like me will feel very cut their hands. Every time they slide out, they will rub against the metal frame, and they will feel that their hands will not be calloused. ...
And like this, when you watch the video on the horizontal screen, the thinnest part of the border is always pointing at your finger:
Compared with 2.5D glass and mobile phone with smooth transition, it feels much worse:
Maybe the designer means that it is more convenient to film, so I'd better buy a 2.5D tempered glass film. ...
The verb (verb's abbreviation) ID has no border.
I don't know what evil happened to the designer of Xiaomi 5 this time. On the white model of Xiaomi 5, they used the ID borderless design of LeTV and Huawei, which have been vomited by netizens for countless times. Whether it is the psychological gap after the screen is turned off or the strong contrast between the black edge and the white panel, it is very uncomfortable to think about it.
In fact, its border is not thick. Take a ruler and measure it carefully, but this black border design is too appetizing.
Sixth, the fingerprint recognition rate is low because the physical home key is too small.
This Home button on Xiaomi 5 is the first time Xiaomi has used the front physical button, and it is also the first time Xiaomi has used the front fingerprint recognition. Its recognition speed and press feedback are very fast. But this Home button is a little too small and slender. Compare it with other mobile phones with Home button.
Visually, this makes the mobile phone chin particularly large; Moreover, the pressure is also high when pressing, which is time-consuming and laborious.
At the same time, because the recognition area is small, you are required to press it accurately, and your fingers will not be recognized even if they are slightly up and down. Let me compare it with the unlock identification of R9 here:

R9 fingerprint unlocking test
It can be seen that it is also a quick click to unlock, and the success rate of Xiaomi 5 may be less than 70%. I feel that you have to aim at it for a while to unlock it smoothly; The R9 bright screen of the big Home button was unlocked in one go, which was basically successful without any delay.
Fingerprints can only be used to unlock the screen and Xiaomi's own application, and Alipay and WeChat payment are not supported for the time being. In addition, I like it very much. The last operation on MIUI to turn on the flashlight quickly can't be completed now-in the past, when I locked the screen, I pressed the Home button to turn on the flashlight. Now I can unlock it directly and enter the desktop ... After consulting customer service, I said that this operation was cancelled on Mi 5 ... Unhappy? _?
Seven, the card slot does not support TF card expansion.
Xiaomi 5 supports full netcom 3.0 and dual card dual standby, but it is not the popular "and or card slot" recently, and can only insert dual nano-sim cards. If you add a sim card slot, you can't change it into a micro SD(TF) card like many other dual-card models.
Universal sum or card slot
Eight, the power button is loose
As soon as I got started, I felt that the buttons on my mobile phone were a little loose, especially the power button, which swayed.
I thought it was an example. I searched online and it was still the same. It seems that it is really a common problem, and it is also a sweat.
Nine, the charging interface is not universal
This time, Xiaomi 5 adopts QC3.0 fast charging and USB Type-C interface, which has fast charging speed and is very user-friendly. However, Type-C is not a popular interface at present, so you need to always carry its standard charger, otherwise once you go out without electricity, other people's charging cables are not compatible with yours. ...
I suggest you put a spare adapter or data cable in official website, in case you can't charge it outside. In fact, just one more Xiaomi 5.
finally ...
Xiaomi 5, as an iterative new product that appeared after the release of the previous generation1September, really represents a new height of Xiaomi mobile phone, but after use, you can still feel flaws and regrets, especially in design details and workmanship. I always think it will take a little time.
If you are an old user who pays special attention to the performance of mobile phones and is used to MIUI, you can definitely satisfy you. After all, the domestic mobile phone using Qualcomm Xiaolong 820 was officially listed this year (although it still needs to be robbed); And if you are a user who pays special attention to the details of workmanship and feel experience, I suggest you go to the offline store to experience it before making a decision.
