One cell phone in the water
Today, people buy mobile phones more likely to see configurations, screen sizes and photographs. There is, however, a lack of attention to waterproof mobile phones。
But in my personal experience, cell phone waterproof design is essential. I myself accidentally put my pants with iphone 4s in the washing machine, and then came back a few minutes later, but i couldn't save it; my grandfather's old phone just fell on the beach and was washed away by sea; the same experience happened to one of my colleagues, who took high-end mobile phones from the national budget and put them in his pocket, causing the machine's internal circuits to be scraped off at short notice; and colleagues around him shared the experiences of people who dropped their phones in the toilet, swimming pools, and even sweating and wetting them. One event made me realize that the waterproofness of mobile phones is really important
Cell phones are in the water
The three most common factors that currently lead to cell phone damage can be attributed to the fragmentation of the screen, the ageing of batteries and the introduction of water. The screens can be replaced with new screens through multiple channels, the batteries can be replaced by mobile phone repair shops if they are old, but the damage is not only large-scale but almost irretrievable, so when the cell phone is damaged, if not a completely new machine, it can almost be declared dead。
Micro-specify iphone 4s water entry leading to yellow solid oxide around the connector short circuit
Maybe you'll ask why water is so dangerous. Why can't it be repaired? Take the example of the iphone 4s that i used to run out of water before, when you took the machine out of the water, you would see that the position of the connector is already producing yellow and green solids, because this part is often passing through large currents, and because it's not very secure here, when the liquid that feeds the power comes in, it's bound to create short circuits and burn the connector to produce oxidation. The impact of short circuits on internal circuits is significant, not only because it burns the connectors, but also because of the high probability of damage to other chips or components connected to them. It is common practice to replace the main panels, even when some manufacturers sell without the condition of repairing the main circuits。
A quote from apple network for maintenance costs other than iphone screens or batteries
Tragically, however, the vast majority of mobile phone manufacturers do not use machine water as a free maintenance service provision, that is to say, you have to pay a high cost of switchboard replacement to fix the phone. In the case of iphone, for example, it is understood that the official price of apples for screen damage and battery replacement is clear and can be found online, while the cost of out-of-pocket maintenance of damaged apples in other areas is also given, but prices are staggering, such as the maintenance cost of iphone x, which amounts to $4548, and the purchase of a mini-mix 2s with an 8gb memory of 256 gb, is sufficient to produce more than $500; even the cheapest iphone se maintenance price has reached 1980。
The main board maintenance cost for vivo x21 is $1190
Turning to another manufacturer's product, the vivo x21 screen fingerprint version, the machine had a clear offer on the official web for replacement fittings, of which the main plate was the most expensive of all the accessories and, although priced better than apples, it also amounted to $1190, or about one third of the machine's sales price. So, apart from preventing the machine from falling into pieces, you should be careful not to let the machine into the water, or the price will be huge
Two waterproof phones are always available and are evolving
Waterproof phones are always available, and they're evolving
In fact, when it comes to the protection of mobile phones, it is believed that people from the functional age must have heard of the triple-protective phones, which are self-contained, with a strong sense of skin muscles, and are designed boldly and thickly, usually using rubber and plastic materials, because both of which guarantee greater resistance to bumping and are well sealed, but they also have obvious disadvantages, namely that they are large and thick, and that they are difficult to meet the standards of mainstream aesthetics。
When it comes to waterproof phones in the age of functional machines, it's probably the way you remember them first
In the age of smart machines, with the proliferation of large screens, mobile phone designs have evolved towards a more contours of routing. So mobile phone manufacturers are thinking about how to design a waterproof cell phone that fits the mainstream aesthetic。
Moto defy was the first smart machine to use water protection as the main selling point, and sony later introduced water protection designs into the fashion-tide flag-ship type, where he reaped a great deal as the core selling point of the product. In recent years, more and more water-resistant mobile phones have become the standard for top-class flagship mobile phones, such as the samsung s9 series, the chinese p20 pro series and the apple iphone x. They all addressed the pain of the previous waterproof mobile phones, which were swollen, and which had to be blocked by seals. This is a revolutionary advance in the waterproof design of mobile phones。
The waterproof design of mobile phones today will have little impact on the public, but the cost of high waterproofing will increase
But you might ask why waterproofing is used only on flagships, but not ordinary phones, since the problem of early waterproofing phone design is solved. In fact, today's mobile phone designers take into account the sealedness of the product and its anti-coat resistance at the outset of its design, but because of cost, the product has compromised its capabilities in various areas。
So let's figure out why the waterproofing of a mobile phone cost more. We know that the purpose of waterproofing design is to avoid short circuits in which liquids enter the machine, so what the designer needs to do is to block all holes that may allow water to enter, which is an early solution; today, with the increased precision of cell phone components processing and the emergence of internal components specifically designed for waterproofing, we no longer need rubber plugs, but special sealing for different parts。
Orange rubber seal inside iphone 7plus silent key
Black rubber seal on the neck of iphone 8 plus sim
In the example of the iphone type that i've previously dismantled, they have an ip67 level of dustproof water, and in order to do this, their keycaps, data interfaces and sim slots are embedded in a rubber ring, with higher heights than attached materials, so that when entering the open part of the body, the higher part can be squeezed between the parts and the openings of the body, sequestering the internal and external parts and protecting against water. This circle of rubber, however, is not readily manufactured, but needs to be accompanied by a finely processed slot on the component to produce it at a very small thickness error。
Tristar s7 headphones are based on liquid silicone injection
In addition to rubber ring seals, some manufacturers have attempted to seal them with new material technologies. Samsung, for example, “squeezed” elements on the machine, rather than embedding them into the fuselage, using liquid silicone injection-forming techniques on s-series phones for almost two years。
Gore-tex technology is used in the soundhole of the tristar s7 speaker
However, the sounding hole cannot be sealed as directly as the other openings, because the sound has to go out. So new solutions must be adopted for the soundproof water sealing of loudspeakers, while the three stars, using gore-tex fabric technology, produce thin film that can keep the water out of the thin membranes, while the air can move freely from inside and outside the machine, thus not affecting the transmission of sound。
Vivo x20 phone master plate: connectors are surrounded by sealed bubbles, naked circuits are all sealed in black
But would it be enough to block the outside? The current technology of sealing will decrease its capacity as mobile phone usage increases. What if the phone is still in water? This involves waterproofing the inner circuits of mobile phones. The internal waterproofing of mobile phones, as currently known to the author, involves the application of a little glue to the naked circuit, the design of a containment bubble around the connector, and the plating of the circuits with a nano-waterproof film, which can effectively reduce the risk of short circuits occurring inside the cell phone once it enters the water. However, there are few manufacturers that have adopted this design, and the international version of the post-appiphone 6s is used internationally, and only some of the high-end versions of oppo and vivo are used in the country. It is, however, incomprehensible that the latter do not deliberately promote the waterproofness of products。
As a result, the waterproofing technology of mobile phones is highly knowledgeable and does require some input from the manufacturer。
How do we judge the waterproofness of a cell phone
Since a good waterproof cell phone requires a huge cost to the manufacturer, does that mean that other medium- and low-end phones, except for flagship products, are out of waterproof? Of course not. As i said before, waterproofness is a very important product quality indicator at the beginning of the design. Only some product managers do not believe that mobile phones need to be fully waterproof, as such use is very rare, but the cost of input is high。
So, a new concept of water protection was born, that of water protection. There is no precise definition of what constitutes life-resistant water, but it is generally understood by industry to be water-proof. For example, when washing hands, the mobile phone is placed next to the pool, and when washing hands, the water splashing on the machine does not cause problems, so the product has a life-proof capacity。
How do we judge the waterproofness of mobile phones
But as an ordinary consumer, you may wonder how we can judge the waterproofness of a mobile phone in addition to the propaganda of the manufacturer. Here, i would like to introduce you to a few small identification techniques:
1: look at the gap between the parts of the hole. The requirements for good product control for waterproof design are naturally high, because to ensure that the opening space is small enough, it is clear that this is a good starting point for intrusion into internal circuits if it is to be seen in the open space where there is a gap that should not have existed, or if there is a relaxation of parts such as button caps。
2: see if sim kato has a rubber ring on his neck. The number of mobile phones using this design in the first place is not large, but once used, it is sufficient to show that the machine is very deliberate in waterproof design。
3: look at the extent to which screen glass, back casings are connected to the frame in the body. Remember that when mobile phones used to replace batteries in the early years, the shell could be opened with fingernails, a design that was almost destined to be less secure, so the closeness of the jacket and glass cover to the fuselage was also an important sealing indicator. In some cases, because of poor public transport controls or the use of time processes, there may even be cases of glass lids or back casings that would naturally be less secure。
In our disassembly articles, there will be subjective evaluations of product-specific design, including waterproof design, for your information
4: see the dismantling report. The above three articles, although of some reference value for identifying water protection capabilities, are not really very effective. When mobile phones are dismantled, the waterproof design of the internal component becomes apparent. If you can't determine from a decomposition picture whether the cell phone's waterproofing design is good or bad, then the second page of our product dismantling article will be devoted to a subjective evaluation of all aspects of the product's design. Readers can visualize the waterproofness of the product from the point of view of a professional decomposing editor。
End: the waterproof function should attract the attention of the manufacturer, not just the head
As the closest digital partner of humankind, the life of a mobile phone is undoubtedly the main focus of attention, but the reality is that more attention is being paid to the size of the screen, performance, photo, etc. The editor therefore calls for attention to be paid to the waterproofness of mobile phones, which are closely linked to their useful life. But for the producers, improving the waterproofness of the product is one side, and should the post-sale policy for cell phones be adjusted
Last august, sony was the subject of a collective lawsuit by united states consumers for waterproofing products in advertising, but for damage caused by water intrusion without warranty, which was eventually lost on suspicion of false propaganda. Subsequently, none of the other mobile phone manufacturers dared to raise the waterproofness of their products. It is important to know that very few manufacturers in the current industry dare to include products in free coverage. This brings us to the realization that, despite the current advanced water protection technology of mobile phones, it is still difficult to guarantee a perfect resistance to water. So, the waterproof road to mobile phones is a long way to go, and there's still a lot to go。
