Is Apple exaggerating the iPhone’s water resistance?


Many users often mistakenly think that the iPhone can operate for a long time in different water environments, even at the swimming pool and at sea due to some obscure advertisements recently.

“Apparently the iPhone is waterproof, but why do I take pictures in the swimming pool, the phone is damaged due to the water entering”. Angry users in New York, USA sued Apple for amplifying the water resistance of the iPhone. This makes users mistakenly think that the iPhone can work for a long time in different water environments, even in swimming pools and at sea.

A plaintiff named Antoinette Smith said that after watching a TV commercial about the iPhone’s waterproof feature, she took a few underwater pictures with her phone while she was traveling. As a result, Antoinette Smith’s iPhone turned into a brick, while Apple refused to provide a free replacement or warranty.

Not only AppleMany other leading smartphone manufacturers have also encountered similar problems due to the recent overstated waterproof performance ads. So why does something still happen when exposed to water when manufacturers claim the phone is waterproof?

Possessing a “waterproof function” does not mean that users can take the smartphone to swim or go diving, or let the phone dry naturally after being exposed to water. This function can only guarantee that water will not enter certain key components and sites and cause damage under certain “short term exposure to water” conditions.

In fact, once normal water gets inside the phone, it can cause condensation in the camera to blur photos, deteriorate sound quality, corrosion on the board making the phone unable to charge. , cannot be started. Therefore, to ensure the phone can operate stably, users also need to have knowledge of some specific functions.

Mobile phone water resistance

Smartphones today often use 2 methods to achieve performance in terms of water resistance. In it, the first method is waterproofing from the structure, by reducing pressure on the gaps in the body, then adding rubber bands and gaskets to increase the waterproofing ability.

The second method is to apply nano waterproof technology, which is to coat the entire surface of the product with a polymer layer with a thickness calculated by nonomet, which can be attached to the surface of the product in the form of a molecule. When the liquid comes into contact with the coating, it will condense into water droplets and the appearance of the material remains unchanged, making it resistant to water or sweat.

The reason smartphones like Apple and Samsung Galaxy can be used in water environments (such as underwater photography) for a short time, while the headphone jack and charging port are still open due to waterproof technology. nano.

So waterproof for smartphones will be based on IP performance, which is a standard set by the IEC. IP here stands for Ingress Protection, meaning the level of protection against the intrusion of foreign objects outside the phone. The IP rating system is denoted by IPXX (0 ~ 6 and 0 ~ 8), the first X represents the dust resistance level and the second X represents the waterproof level.

To put it simply like the phone repairmen and used old machine dealers in Vietnam, “still applied” or “lost pressure” is for smartphones that still have or have lost their water resistance. This is something to note if users have a need to buy old phones.

Since the iPhone 12, Samsung Galaxy 21 and several other phone models came out with IP68 water resistance. Some users are affected by ad streams and believe that water resistance has become absolute, so they get in the habit of bypassing a series of manufacturer-defined restrictions, resulting in phones that can broken after soaking in water for a long time.

The rescue plan for the flooded phone

In case the “mobile phone” is unfortunately exposed to water, some iPhone and Samsung models will display red on the waterproof label on the motherboard and sim slot. In addition, some other smartphones will directly turn on the warning window when liquid enters the charging port to remind the user, this warning will disappear when the liquid has been dried.

Some people have a habit of stuffing their phones into rice after being wet with water. But this is an ineffective, even damaged way because grains of rice and dust can get into the phone through the charging port, speakers or where the headphones are plugged in. It is best to immediately turn off the phone when caught by water or after exposure to liquid, and then dry it with a clean cloth or paper towel.

If there is liquid left in the charging slot, gently shake the phone to let the liquid out. Continue drying the sim card slot using the freeze drying of the dryer, if using the hot drying mode it may damage the waterproof tape and LCD screen. Placing your phone in a sealed bag that contains a desiccant pack is also an effective way to gradually remove any residual moisture.

Also, it should be noted that with some phone models, such as the iPhone, charging should only take place after 5 hours after reaching a completely dry state. If the mobile phone still does not work properly after completing the above steps, please go to a professional repair site and do not attempt to resolve the problem by disassembling the mobile phone yourself.
