Waterproof phone can do whatever you want?

After buying a waterproof mobile phone, many friends feel foolproof, and begin to unscrupulously let their mobile phones frequently contact water, and even go to the sea to take pictures. In fact, this is very inappropriate, the mobile phone protection level test uses specific parameters, and sometimes it is not consistent with the scene in life.

Han Dongxiao, general manager of Shenzhou Tech Testing Laboratory, which has just obtained the national laboratory accreditation qualification from the China National Accreditation Service for Conformity Assessment (CNAS), stressed that even if the phone reaches a certain waterproof level, it does not mean that it can be safe and sound in the water under any circumstances. At present, IPX7 devices with higher waterproof have a maximum immersion depth of 1 meter, and in deeper water than this, the pressure is too high, which may make the waterproof fail.

Generally, the laboratory tests the waterproof function of the mobile phone, using pure water at room temperature. We should keep our phones out of contact with seawater, pool water (which contains high concentrations of chlorine), soaps, shower gels, alcohol, juices, drinks, etc. These fluids can exacerbate corrosion of waterproofing elements or cause other problems.

In case of these emergencies, the phone should be rinsed with clean water as soon as possible and dried.

Secondly, even if it is clean water, you should pay attention to its temperature, and the higher the temperature of the water may also affect the waterproof performance of the phone, causing water damage to the phone. If your phone accidentally falls into the soup, the warmer soup may cause the waterproof parts to fail.

Finally, water resistance also deteriorates with prolonged use. In fact, waterproof mobile phones that have just left the factory can meet the waterproof standards of the original design because all the components meet the design requirements (large brand manufacturers will also make the design margin larger). However, bumps and bumps will inevitably occur in the hands of the user, and the slight deformation of the waterproof parts will lead to the attenuation of the waterproof performance.

Waterproof mobile phones can not do whatever you want, to know the degree to which the mobile phone can be waterproof, now most mobile phones are waterproof for life, a few can reach IP68 waterproof, that is, it can last for 30 minutes under rice water, love outdoor (ioutdoor) wind can be 3 meters waterproof.

What are the waterproof phones, there are currently Sony Xperia XZ2P, Huawei P20 Pro, Apple iPhone XS, Samsung Galaxy S9 and S9 Plus, Huawei P30 Pro, etc.

1. Sony Xperia XZ2P

Its weight is close to 250 grams. The phone is equipped with an inch of 4K-class ultra-clear screen with a screen resolution of 3840x2160 pixels and a screen pixel density of up to an astonishing 760ppi. You must know that Apple's upcoming iPhone XR has a screen PPI of only 326.

2. Huawei P20 Pro

Huawei's flagship mobile phone released in the first half of this year is equipped with a Kirin 970 processor, notch screen design, and the screen pixel density reaches 408ppi. The biggest feature of the camera is that it is equipped with four cameras (one in the first and three in the back), and its photo score has long dominated the first position in the DXO rankings.

3. Samsung Galaxy S9 and S9 Plus

Samsung's machine is equipped with a Qualcomm Snapdragon 845 processor, a currently the world's best inch curved OLED flexible screen, with a screen pixel density of up to 568ppi. The symmetrical narrow bezel up and down can effectively ** the resistance of OCD to the notch screen.

4. Apple iPhone XS

Apple's recently released 2018 flagship phone is equipped with an A12 bionic processor, with a self-developed GPU, so that the Antutu running score of the whole machine is as high as 350,000, and the waterproof performance is super invincible. From S8 to S9, its waterproof rating is IP68.

Apple phones have a waterproof function, and iPhones with Apple 7 and above versions support waterproof function.

The iPhone 7 already supports IP67 standard waterproofing, which can last up to 1 meter deep in water for 30 minutes.

The home button of the iPhone 7 has a new design, including the lack of feed from the vibration anti-car. It also supports IP67 splash, water, and dust resistance, front and rear single cameras, shock resistance, and the new faster A10Fusion processor.

The iPhone 7 has been tested in a controlled laboratory, and the results show that it meets the international standard Luwei IEC60529 with an IP67 rating. However, its waterproof, dustproof, and splash-proof functions are not permanent, and their performance will decrease with the increase in the frequency of daily use.

The front of the iPhone 8 is the same as the iPhone 7, the buttons on the main screen are the same, the space-grade aluminum design, the front and rear glass reflectors, water and dust resistance, and wireless charging.

Precautions for the use of waterproof mobile phones:

1. The safest waterproof mobile phone is fresh water below 30, and the water temperature is too high to make the gasket age, thus losing the waterproof ability. The salt contained in seawater can easily rust the metal parts, the keys are difficult to operate, and even corrode the circuit, so it is best to soak the phone in fresh water for a few hours after using it in the seaside or in seawater.

2. Most waterproof mobile phones have dustproof functions, but larger particles of sand or soil are fatal killers to mobile phones, be sure to replace the battery or memory card before operation, open the sealing cover, and rinse it with water. Otherwise, once the sand adheres to the sealing area, it is easy to cause the rubber gasket to deform and leak.

3. The battery and the sealing cover on the interface can be said to be the weakest link of a waterproof mobile phone. Before each phone goes into the water, we should carefully check the clamping of the sealing cover to confirm that it is closed. Be extra careful when opening.

If you have just soaked in water, wipe the water on the body with a soft cloth to avoid seeping in.

4. If your waterproof mobile phone does not have a shock-resistant function, you should avoid knocking, because it is likely to cause the sealing interface to loosen at the moment of impact.

Take a shower in life, occasionally dip a little water does not affect the use, and it is okay to accidentally fall into the water and fish it out immediately when washing your hands, and it is not okay to soak it for a long time. Huisheng can't be built because the mobile phone has a little waterproof function, after all, it is an electronic product, once the mobile phone is defective, it will be scrapped.
