About the waterproof IP rating of smartphones

Manufacturers of phones, smartwatches, and other devices will tell you that your device is waterproof. But the actual water resistance of Apple, Sony and Samsung is different. The word “IP rating” is often used to refer to a phone or device that is exposed to water or moisture. It is an international standard that sets the level of protection against dust and solids.

Phone X, iPhone 8, Samsung Galaxy S8, Sony Xperia XZ1, Apple Watch 3 are all waterproof. However, not all of them have the same IP rating. The Samsung Galaxy S8, Note 8, and Sony Xperia XZ Premium have IP68, while the iPhone X and iPhone 8 have IP67. The word “IP” stands for “ingress protection“. This means measuring how easily dust and water can easily get inside your device. The IP is the same, and only the following numbers determine how resistant the phone is. The last two digits of the letter P (for example, IP 67) indicate that the front one protects against dust (for example, sand and dust on the beach). Its numbers can be 5 or 6.

Number 5 does not completely prevent the inside of the phone from getting inside, but it does prevent it from interfering to the extent that it interferes with the internal functions. However, the number 6 can fully protect against dust and sand. Sometimes you see phone companies refer to their phones as IPX8. Instead of specifying the dust resistance of their products, they are replaced with “X“. The second number in the IP rating is the water resistance of the device.

He is a little more complicated. Almost all mobile phones have IP ratings starting from 3 to 4. 3, 4 and 4 can protect against water level flooding and will not be damaged even if it gets wet due to rainwater. No. 5 is waterproof to 6.3mm. No. 6 protects against water from 12.5mm. These are just the tip of the iceberg. The real water resistance is 7’s. 7 can protect you even if you fall 1 meter under the water.

However, if it is more than 1 meter, it must be safe from the latest IP 68. But no phone is completely waterproof yet. When it comes to water resistance level 9, you know how many hours it can last even if you fall into the water. This is the kind of phone that can be completely protected. Some phones do not get badly damaged for a while, even if they are flooded.
