Waterproof smartphones with an IP rating are more common on the market. So once this standard remained reserved to the Sony Xperia Z and some models by here and there, everything changed since Samsung and Apple have started offering the standard on their latest high-end models. By the way, do you know the difference between a certified smartphone IP67 and IP68 certified smartphone and do you know why some models are tighter than others?

what does the IP certification?

The IP certification shows you through two numbers to what degree your smartphone (or other electronic product) is resistant to water and dust. The first number shows the degree of resistance of the device to solids such as dust, the second tells you about resistance to liquids.

As you can imagine, the higher these numbers, more your smartphone is resistant. Note that there are times that some devices such as the Motorola Moto G 2015 are certified only IPX7. This means that it is only water resistant but for no rating for protection against solid bodies or that it for not been measured. It is also possible that the X (not measured protection) be replaced by a zero which means that there is really no protection.

As you can see, the maximum degree of protection for solids is 6 whereas for liquids, it is 9K.

First digit: resistance to solid bodies

  • 0 or X : no protection or protection not measured
  • 1 : protection against solid bodies higher than 50 mm diameter
  • 2 : protection against solid bodies higher than 12.5 mm in diameter
  • 3 : protection against solid bodies higher than 2.5 mm in diameter
  • 4 : protection against solid bodies higher than 1 mm in diameter
  • 5 : limited protection against dust
  • 6 : total protection against dust

Second digit: resistance to liquids

  • 0 or X : no protection or protection not measured
  • 1 : protection against the vertical falling drops of water (very limited index)
  • 2 : protection against falls (15 °) vertical water drops
  • 3 : protection from rain (60 °)
  • 4 : protection against splash water (all directions)
  • 5 : protection against jets of water (all directions)
  • 6: protection against strong jets of water (all directions)
  • 7 : protection against immersion (maximum 1 meter for 30 minutes)
  • 8 : protection against immersion (beyond 1 meter for 30 minute maximum)
  • 9: protection against immersion (beyond 1 meter) and against high-pressure cleanings. When a device is certified IPX9, it is generally tightly closed
  • 9K : resists cleaning at high pressure and high temperature

the water protection is directly related to pressure, reason why there are several degrees of protection. The immersion is possible from 7 index and only from index 9 high pressure cleaning. The Galaxy S7 and S7 Edge , for example, are totally protected against dust and can withstand immersion beyond a meter, as well as the Sony Xperia latest (since the Z3). On the other hand, the iPhone 7 (IP67) isn’t supposed to resist more than a meter deep.

Note that the IP68 protection class is the strongest currently available for smartphones. In summary, a smartphone can be totally protected against dust, if not (yet) possible with water since none are still going beyond index IPX8 /IP68

the Galaxy S7 is waterproof but only up to a point
