With the release of Xiaomi 10, the mobile phone market war at the beginning of the year is officially started. From a product point of view, this Xiaomi Mi 10 really can be called a “configured full” bucket machine, but the small flaw is still reluctant to retire the 1080P screen and P2i dust and water resistance.
Unlike common IP, what is this P2i? How about the actual waterproof performance?
Not a level, strong> It’s the company name
As a precision electronic consumer product, the protection of mobile phones against accidental injuries has always been one of the key concerns of mobile phone manufacturers. This time, Xiaomi provided P2i waterproofing on mobile phones, and did not identify the traditional IP dustproof and waterproof level. See It looks like a new three-proof standard.
But in fact P2i is not a new three defense standard or a new indicator. This is just the name of a company-“Perform Protect Improve”, referred to as P2i.
This is a British company engaged inThe main task of nanotechnology development is to rely on a “perfluorocarbon polymer coating” to reduce the surface energy of the object, so that the liquid on the surface of the coating will become bead-like, instead of penetrating or being absorbed by the object, thereby preventing Corrosive circuits.
In principle, it approaches the principle of hydrophobicity on the surface of lotus leaves.
To achieve this technology, the coating chamber needs to be pumped to a negative pressure, and the surface activity is activated by RF. After that, the coating will enter the coating chamber in the form of steam, and rely on a low-pressure environment to attach to all objects in the chamber. Form a polymeric layer with only a few nanometers.
From the description of P2i’s official website, most electronic components can achieve this coating method. After coating, the appearance and touch of the object are basically the same as the original, but the waterproof function is added.
At present, this technology is mainly used on mobile phones in places where the liquid is easily contacted, such as headphone jacks, data cable jacks, and circuit boards, which are prone to problems. It is protected from liquids such as splashing water, rain, and sweat. , Thereby extending the life of the phone.
As early as 2012, Motorola launched the RAZR XT910 using P2i waterproof technology; headset manufacturer Plantronics also used P2i coating to achieve waterproofing of headphones; Xiaomi is not the first time to use P2i waterproof coating, from Redmi Note 7 to Xiaomi 9 have P2i shadows.

So translate it: the correct explanation for the so-called P2i waterproofing is “using P2i’s waterproofing technology”, rather than “P2i waterproofing level”. There is no P2i waterproofing level at all.
Waterproof, strong> Not anti-handy
The correct expression of the waterproof level of mobile phones is currently based on the “international Protection” IP rating, followed by two digits, the first one indicates the dustproof level, and the second digit indicates the waterproof level.
At present, both the media and manufacturers tend to benchmark the P2i’s waterproof level around IPX2, which means “drip-proof”, which means that it can achieve a relatively limited life waterproof.
Anyway, it ’s better than nothing.
Currently, in addition to mobile phones with nano-coating technology, there are also ways to achieve waterproofing by adding a sealant in the fuselage. Although this can make the phone more waterproof and dustproof, it will also occupy a part of the fuselage Space, in this increasingly integrated environment, there are fewer and fewer mobile phones equipped with waterproof glue.

However, the nominal waterproof rating does not mean that the waterproof performance of the mobile phone is completely reliable. The test environment in the laboratory is subject to strict conditions. The water used is basically purified pure water. The actual use environment in real life is much more complicated, including tap water containing chlorine, bath water with temperature, rainwater containing impurities, seawater containing salt, etc., all of which will cause the experimental nominal level of the waterproof performance of mobile phones Outside influence.
In addition, with daily use, the waterproof coating on the interface will wear out with continuous use, and the waterproof performance will continue to decline.
Although mobile phone manufacturers usually indicate the waterproof and dustproof performance of mobile phones, they will also carry out a certain degree of publicity. However, if the mobile phone accidentally enters the water and causes quality problems, the normal warranty is usually not performed. Because manufacturers can’t judge the use environment when water is in, nor can they judge the age of the waterproof parts of the mobile phone at that time.
