The iPhone 7 is IP67 certified, which is similar to the original Apple Watch. The Samsung Galaxy S8, meanwhile, is IP68 certified. What do these things mean? Which one is superior? And why should you care?
What do certifications do?
Most modern smartphones have these certifications attached depending on how resistant they are to the elements; dust particles and water, but what do the ratings stand for?
IP – This stands for the International Protection marking, a standard drawn up by the International Electrotechnical Commission (IEC).
Dust resistance is mostly measured on a scale of 0 to 6. With ‘0’ offering no protection, to ‘5’ and ‘6’ offering levels of protection from contact with harmful dust. So, a smartphone with an IP rating of say IP53 has 5 as the first digit. The first digit stands for its resistance to dust, but also general dirt and sand.
For example, the Samsung Galaxy S8 earned a ‘6’ rating for “No ingress of dust; complete protection against contact (dust tight)” following an 8-hour test.
Water Resistance The second digit provides certification for water resistance. This is the important bit this is measured on a scale of 0 to 8 with 0 offering no protection against water or moisture in any form to 8 offering protection from immersion in water to a depth of more than 1 meter.
What Should You Buy?
Manufactures nowadays are making devices more reliable and much more resistant to things like dust, chemicals and water. It isn’t a surprise really. Consumers don’t want thinner devices as much as they want long-lasting devices. Next time you’re picking up a phone, go for IP67 or better! If your current device isn’t certified well enough, it may be time to sell.
