In order to make 5G mobile phones thin and light, manufacturers have made so many efforts

"Snapped"

whenCell phoneYou must be praying for the phone to not be too heavy the moment before you get in touch with your face.

Almost everyone who likes to lie down and play with a mobile phone may have had the experience of being "sanctioned" by the mobile phone. Whenever you encounter this situation, a thin and light mobile phone looks very cute. After all, it is horrible to think about being smashed in the face by a "half catty machine".

For a long time, “light and thin” has been regarded as the added value of mobile phones, but with the continuous development of the smartphone industry and the improvement of user aesthetics and user experience, light and thin has become a wider demand.

However, when looking back at the beginning of 5G mobile phones, thin and light and 5G have become a couple. When the first wave of 5G mobile phones were launched, the weight was generally around 220g, which was worthy of the name "half a catty." Even today, 5G mobile phones are getting thinner and lighter, but they still leave users with the inherent impression of "too heavy" and "too thick".

1. People have a bottleneck in the perception of thin and light mobile phones

There is no doubt that users have a strong perception of the weight and thickness of mobile phones. The gap between a mobile phone is about 20g and 0.5mm, and the hand feel will be significantly different. When a mobile phone reaches 220g and 10mm or more, it may be uncomfortable to hold it for a long time.

Before the emergence of 5G mobile phones, the public's requirements for the weight and thickness of smart phones would basically not exceed 200g and 8.5mm. Even for flagship products with the most stockpiles, the control of thickness and weight is basically maintained below this level, such asHuawei P30 ProThe weight is 192g and the thickness is 8.4mm;Samsung S10+The weight is 175g, the thickness is 7.8mm and so on.

In the 5G era, the “successors” of the top-equipped flagships have become thicker and heavier.Huawei P40 Pro+It even reached 226g and 9.0mm; Samsung S20 Ultra also reached 220g and 8.8mm.

This sudden change makes it difficult for users who are accustomed to 4G mobile phones to adapt. Especially for heavy mobile phone users, they are most sensitive to the weight of the mobile phone. After all, they need to hold the mobile phone for a long time. If you use one hand, Watching videos, playing games, chatting and reading with these 220g guys are still quite falling.

However, manufacturers obviously also understand that 5G mobile phones are too heavy for a long time. Therefore, since last year, the entire industry has actually begun to re-enter the thin and light design route. IDC data shows that starting from the second half of 2019, the proportion of products weighing more than 190g has continued to increase, and even approached 90% by the end of the year. However, as of June 2020, thin and light mobile phones below 190g have occupied about half of the market and have gradually become the mainstream.

In terms of domestic mobile phones, OPPO was one of the first manufacturers to control the weight and thickness of their products. As early as 19 years, they released the Reno3 series that focuses on thin and light 5G, even at the flagship level.Find X2Series andAce2They are also products that focus on thin and light design.

Nowadays, not only OPPO, but the trend of 5G thinness and lightness has begun to spread to the whole industry. It has become very common to regard “lightness and thinness” as a selling point of 5G mobile phones.

2. Is it thin or light? Consumer: I want

Of course, this process did not happen overnight, which is why the first wave of 5G mobile phones were so thick and heavy that they did not gradually return to lightness until a year later. This shows that manufacturers have also made a lot of efforts during this period and overcome many problems.

As we all know, the biggest difference between 5G mobile phones and 4G mobile phones is the addition of 5G radio frequency, 5G antennas, and the addition of larger heat dissipation modules. The increase in the number of components not only takes up more body space, but also consumes power. This is a further improvement, which is why everyone always feels that 5G mobile phones consume more power.

There is no doubt that if you want to provide users with a hearty 5G experience, mobile phones must make a fuss about battery capacity. In the 4G era, a 4000mAh battery can be called a "big battery", but in the 5G era, this is a little stretched. In order to ensure long battery life, 5G mobile phones generally use larger batteries. But contradictions also arise. One is a large battery, the other is thin and light, and there is always one to make concessions and compromises.

But consumers are not manufacturers. Users only care about the actual product experience. Only 5G mobile phones with large-capacity batteries and thin and light feel are the products that consumers really favor. Manufacturers naturally understand this truth, but everyone knows the truth. How to achieve a balance between battery life and lightness is not easy.

3. It is difficult to make 5G mobile phones thin and light, but OPPO provides a solution

As mentioned earlier, OPPO is one of the manufacturers who recognized that users have such needs earlier, so it can make arrangements early and continue to introduce some thin and light products. In order to achieve a thin and light design, OPPO also took great pains.

Specifically,OPPO Reno5 Pro+ is equipped with powerful configurations such as the Snapdragon 865 processor, 65w super flash charge, 90Hz high-sensitivity curved screen, and three-dimensional liquid cooling, but the weight and thickness are still maintained at 184g and 7.99mm. Obviously, even if the thinness of 5G mobile phones picks up, the degree of thinness is still surprising. This step can be achieved thanks to OPPO's structural changes to the internal space of the mobile phone and a large number of optimizations on components.

It is reported that OPPO has refined the internal components of Reno5 Pro+. For example, the use of a single-layer motherboard design that is different from mainstream stacking motherboards not only reduces the distance between components, but also integrates the circuit design of the PCB part by selecting smaller resistors and capacitors.

For some important components, miniaturization is also performed, and the corresponding number is reduced. At the same time, the wall thickness of the fingerprint holder is reduced to the limit of 0.25mm. The size of the fingerprint module is reduced from 7.25*4.8 to 5.84*4.63, and the bottom space is The overall reduction is 11%, leaving enough space inside the fuselage to put a larger battery.

In addition, Reno5 Pro+ changes the screendriveIC and innovative 6+2 layer flexible circuit board design scheme, on the basis of the previous generation screen, the screen FPC is shortened by 2.35mm, and the motherboard area is reduced by 4% compared with the previous generation. On the heat dissipation module, OPPO also uses the world’s thinnest VC heat sink, and the ultimatecompressionThe longitudinal thickness of the back cover and the inner cover of the mobile phone, the improvement of the internal and external layout structure of the camera module, etc.

Of course, the optimization of the internal space is essentially to make more space for the battery in order to put down a larger capacity battery, which has become the key to ensuring basic battery life. After that, it needs to be supplemented by system-level power saving technology and high-power fast charging solutions to further extend the battery life of the mobile phone. In short, it is not easy to make 5G mobile phones lighter and thinner without sacrificing user experience. OPPO can do it. In addition to hard work, long-term adherence to technological innovation is particularly important.

Finally, there is something to say:

The thin and light mobile phones have always been the unremitting pursuit of consumers and manufacturers. It's just that since entering the 5G era, 5G mobile phones have ushered in greater improvements in both performance and functionality, and they have also brought more challenges to thin and light design. Fortunately, manufacturers have not given up on the exploration of thinner and lighter 5G mobile phones, and have always worked hard to "make thinner by 0.1mm" and "reduce 1g" to present users with moving products.

There is no doubt that thanks to the efforts of manufacturers, the process of thinning and lightening 5G mobile phones has made more progress. I believe that with the continuous advancement and development of technology, manufacturers will be more comfortable in the thin and light design of 5G mobile phones in the near future, which will not only bring thinner and lighter 5G products, but also bring more extreme and comprehensive performance experience, which is worthy of everyone. look forward to.
