When many friends buy mobile phones, in the face of a variety of products, the marketing concept of the sky will be doubtful, it is not an easy thing to buy the desired good mobile phone, and many publicity has the use of consumer one-sided cognition to exaggerate the ingredients. This year's 315 will summarize the misunderstandings that are easiest to enter when buying mobile phones.
Myth 1: The E5 screen must be better than the E4
Starting from E3, Samsung seems to pay special attention to the OLED screen of promoting E series luminous materials, which we can often see at flagship mobile phone conferences, and have undergone iterative updates from E3, E4 to E5 in recent years. But it is based on this naming familiarity that many people will preconceived that the newer the luminescent material is used, the better the quality of the screen.
First of all, the parameters of the screen include many aspects, E5 can only represent the luminous material it uses, which mainly determines the brightness and power consumption of the screen;
Secondly, the screen using E4 substrate is also divided into many grades, in addition to rigidity and flexibility, 1080P and 2K resolution, the peak brightness is also 1200nit ~ 1500nit range, that is to say, the relatively high-grade E4 can be basically the same as E5 in terms of brightness;
In terms of power consumption, combined with the current endurance test data of various media, it is difficult for us to conclude that the model with E5 screen will save a lot more power than E4;
In addition, the viewing angle of the current E5 screen is generally reduced compared to E4, and the color is easy to be cold when looking obliquely, which may be related to the microprism structure it adopts;
In addition, the current 2K specification of the E5 screen are using LTPO backplane, which means that the full brightness of low-frequency PWM dimming, which is not friendly to some strobe sensitive users; and E4 screen 2K and 1080P have LTPS backplane choices, which are DC-like dimming under high brightness, and some models also support anti-flicker protection under low brightness, so that the strobe problem is relatively alleviated.
Similarly, the E4 material has a considerable number of rigid panels, there will be obvious color casts and rainbow patterns at large angles, and the overall display effect is not as good as that of flexible E3.
In general, on the one hand, we can not completely judge the quality of the screen from the luminous substrate, and we must integrate many factors to see; on the other hand, the difference between E4 and E5 itself is not large, and there is no need to be too entangled in the so-called latest E5 screen.
Myth 2: The larger the heat dissipation VC area, the better the performance of the mobile phone
Due to the high power consumption of the flagship chip for many years, the mobile phone often heats up, and the problem of game Caton dropping frames occurs from time to time, so the heat dissipation of the mobile phone has become a hot topic in the near future, and the manufacturers have also continuously flaunted their own luxurious heat dissipation specifications, the most core of which is the material and area of VC liquid cooling. But don't think that the larger the VC heat dissipation area, the stronger the performance release of this mobile phone.
First of all, the higher heat dissipation specifications do help the phone's heat layout to be more even, improving the continuous performance release performance. But after all, it is a small volume and no fan heat dissipation, the efficiency is always very limited, and the heat will still be transmitted to the surface of the mobile phone, making the user feel hot.
In order to avoid this problem, most manufacturers will choose more stringent temperature control to limit the performance release of the processor to achieve the effect of cooling. Admittedly, for most users, the perception of temperature is far more sensitive than the frame rate.
Mobile phones with sufficient heat dissipation are easier to run to full frames in low-and medium-load games such as "Glory of Kings", "League of Legends", "Peace Elite" and so on, but in the face of high-load games such as "Original God" and "Crash 3", it is still common to use the scheduling of down-lock frames.
Therefore, if you pursue the ultimate performance play, it is still necessary to take the evaluation results as the standard, and pay attention to which model is more active in the actual scheduling. Of course, to achieve such performance, but also to ensure that it is not hot, in the current conditions, the heat dissipation back clip is an indispensable accessory.
Myth 3: The higher the memory expansion, the stronger the background capability
With the improvement of mobile phone performance, the APP we use is also more and more diverse and complex, the application's background residency ability is very affective of multitasking, no one wants to open the other three or two software, and then cut back to the original application to reload.
When it comes to the parameters related to background capabilities, many people will think of memory first, after all, everyone is accustomed to calling it running memory, and the higher the capacity, the more software theory can run.
Although the maximum memory of mobile phones has reached 16GB or even 18GB, it is still only the exclusive of niche game phones, and mainstream products are still dominated by 8GB and 12GB. In the past two years, various mobile phone manufacturers have launched a concept called memory fusion (memory expansion), and some manufacturers have even directly shouted out the slogan of "12G seconds to 20G". Giving people a kind of "memory fusion" seems to be comparable to the effect of native super large RAM, is this really the case?
In fact, the so-called memory expansion is not mysterious, it is the virtual memory function built into the Android system. On Cool An, there is a software called Scene, which provides two functions of Swapile and ZRAM, as long as the mobile phone is in the state of ROOT, the user can also set the virtual memory arbitrarily.
Among them, ZRAM is to divide a part of the physical memory, compress the inactive code part of the background application and the foreground application, extract the data when needed, and increase the memory in disguise by reducing the data scale, at the cost of CPU calculation, identify which codes in the APP are not active, and increase the CPU occupation and power consumption.
Swap is to divide a small part of the ROM as RAM to use, can make the system run more programs at the same time, or programs with greater demand for memory, although this implementation is more power-saving, but the read and write speed of flash memory is much lower than that of memory, so the application read efficiency opened in virtual memory will be reduced, and the fluency is not as good as physical memory.
At present, the memory expansion of Various Android manufacturers is mostly based on ZRAM and supplemented by SWAP, and it is necessary to seek a balance between power saving and smoothness as much as possible.
However, the factors that really affect the ability to stay in the background are not only memory, most mobile phones will still adopt a strict background management strategy in order to ensure the fluency of the front-end program and control the power consumption of the whole machine. In this case, let alone virtual memory, even if there is really more physical memory, the background survival rate may be difficult to improve. Therefore, many people turn on virtual memory and find that the experience has hardly improved much.
Myth 4: The higher the main camera pixel, the clearer the photo
Many consumers' misunderstanding of the concept of pixels comes from the era of functional machines, such as 1 million pixels are generally better than 300,000 pixels, which was indeed the case at the time. But the development of smart phones to today, the richness of mobile phone lens design schemes has been far from being comparable to that year, flaunting 100 million pixels of mobile phones emerge in an endless stream, but on the imaging effect is almost almost few can be impressive, it can be seen that high pixels and high quality can not be equated.
This is because camera image quality depends on both the number of pixels and the amount of light ingress per pixel. The camera sensor of the mobile phone itself is limited in size, if the number of pixels is too much, in the environment where the light is not so sufficient, the exposure of each pixel is easy to be insufficient, but it produces more noise and the picture is more blurry.
Mobile phone manufacturers are also well aware of this, so those so-called 100 million pixels, most of them still provide a multi-pixel way, users default to the automatic mode to shoot, get still about 12 million pixels of photos, really want to use 100 million pixels have to manually find the switch.
And there are some drawbacks of 100 million pixels, such as the amount of computing on the mobile phone when shooting, the speed of the film may become slower; too many pixels lead to the sensor can not support the full pixel dual-core focus and other technologies, in the case of the laser focus module is also missing, the focusing ability will become very poor, especially in low-light environments. It can be seen that this technology is still gimmicky larger than the actual, and the high-end flagship that really focuses on images will not be used except for Samsung's own S Ultra.
Myth 5: Hybrid optical zoom
Many manufacturers have marked Xx zoom to attract consumers who pay attention to zoom ability, but users who know a little bit may know that mobile phone zoom is divided into digital zoom and optical zoom, digital zoom is only a simple magnification and cropping of the image, the image quality loss is serious, and the optical zoom multiple is the embodiment of the solid physical focal length.
So the manufacturer has introduced a new concept called hybrid optical zoom. The so-called hybrid optical zoom refers to the loss of detail through another lens after digital zoom, minimizing the loss of quality of the digital zoom, but it is still essentially based on digital zoom, not the "light change" that sounds like the name.
In addition, users who often use ultra-telephoto shooting should also pay attention to whether the telephoto lens has OIS optical image stabilization, and use more than 10 times zoom without image stabilization, it is easy to shake the paste by hand, and the usability is relatively poor.
