The "little secrets" of mobile phones that manufacturers are unwilling to tell, laymen cannot understand, and only insiders know

Regarding smartphones, many years ago, Brother Kan emphasized a point, that is, no smartphone can be 100% perfect and can meet all our needs. Even strong old companies like Apple and Samsung cannot do it. What we can do is to choose a product that can meet our needs to the greatest extent based on our own budget.

However, when choosing a mobile phone, we must have a comprehensive understanding of the product, especially some of the "little secrets" of the mobile phone, because mobile phone manufacturers will not clearly disclose product defects. It is very common to not write down the number of processors or the pixels of the lens. Today we will talk about the "little secrets" of mobile phones that manufacturers are reluctant to disclose, laymen cannot understand, and only insiders know.

Mobile phone storage combination

For smartphones, the most core hardware configuration is undoubtedly the processor. This is why we often see smartphone manufacturers clearly stating that their new phones are the first or the first to be equipped with a certain processor when they release new phones. But at the same time, many mobile phone manufacturers deliberately ignore the storage combination of the phone, which is what we call memory and storage.

Currently, the top storage combinations in the entire smartphone industry are the full-blooded version of LPDDR 5 and the full-blooded version of UFS 3.1, but many flagship phones are not actually equipped with such combinations. Many mobile phone manufacturers still use LPDDR 4X and UFS 3.0, etc.

At the same time, even LPDDR 5 with the same name has differences. The most obvious sign is that some manufacturers will clearly mark it as a full-blood version in front, with a data transmission efficiency of up to 6400 Mbps, while the ordinary version of LPDDR 5 can only reach 5500 Mbps.

Design body material

There are currently four common materials for mobile phone bodies, including plastic, glass, metal and ceramic. At the same time, new materials such as leather and rubber have also appeared on smartphones.

Among them, the most commonly used plastic material is generally polycarbonate, because this material is non-toxic and odorless, easy to process, cheap, easy to process, has good dyeability, is not easy to deform, and does not block signals. However, it also has problems such as poor heat dissipation, poor wear resistance, and poor hand feel. Therefore, it was an ideal material for the production of mobile phone bodies in the early days of the birth of mobile phones, and it is also the body material of current thousand-yuan phones.

At present, "plastic material" basically means cheap. The core purpose of using a plastic middle frame is to control costs, so everyone must be cautious when choosing a new phone. Of course, products such as the Samsung Galaxy S21 mobile phone also have a good polished plastic body.

Mobile phone image parameters

The smartphone industry has been developing for more than a decade, and the core selling points of the entire product can be said to be constantly changing. In the early years, smartphones paid more attention to performance, design, fast charging, etc., while in recent years they have gradually evolved to imaging, the most obvious manifestation of which is the continuous improvement of mobile phone pixels and the increase in cameras.

What we are going to talk about today is the issue of pixels and camera numbers. First of all, the camera itself is indeed related to pixels, but it is also related to many aspects such as sensor size, aperture size, focal length, and system optimization. This is why this year's iPhone still uses 1200W pixels, but it can still beat many Android flagships. So don't just use pixels to judge the imaging strength of a phone.

On the other hand, there is the issue of the number of cameras. Although many smartphones are equipped with multiple cameras, even triple, quad, and penta cameras, etc., there are very few cameras that can be fully used. Cameras like the 5-megapixel portrait and 2-megapixel black-and-white cameras are just make-up lenses. They just show their strength through the number of cameras, but their actual capabilities may not be satisfactory.

Mobile screen quality

Currently, smartphone screens are mainly divided into two types of materials, the first is LCD screen, and the second is OLED screen. OLED screens are mainly supplied by internationally renowned screen manufacturers such as Samsung, LG, BOE, and Visionox, while LCD screens are mainly supplied by domestic screen supply chain manufacturers such as Tianma and BOE. Currently, LCD screens are mainly used in thousand-yuan phones and a few sub-flagships.

Today we are mainly talking about OLED screens. Taking Samsung OLED screens as an example, they are divided into M10 level, E5 level, E4 level, E3 level, E2 level, etc. Among them, top-level screens like M10 level and E5 level are basically exclusive to Samsung, and will be gradually opened to other manufacturers later. Currently, most of the Android camp uses E4 level materials.

Brother Kan

The smartphone industry has been developing for more than ten years, and we have been emphasizing one issue, that is, the information gap. Many smartphone manufacturers use information asymmetry for marketing, which leads to consumers only knowing the good of their products but not the bad. This often leads to all kinds of inexplicable problems after making a choice.

Manufacturers are unwilling to talk about it, and ordinary consumers as laymen don’t understand it either. Only insiders can have a comprehensive understanding of the product. The above four points are the “little secrets” of mobile phones that insiders know. You can use them as a reference so that you won’t fall into the trap when you replace your mobile phone in the future.
