What exactly do IP67, IP68 or IPX8 mean? And can you take your phone swimming? Here's what you should know. Water resistance used to be something found on beefy, rubber-sealed rugged phones designed for construction workers or downhill mountain bikers. But things have changed, and in 2023 you'll find some kind of water resistance built into most mainstream phones, including the iPhone 14 Pro, Galaxy S23 Ultra and Google's Pixel 7 Pro. The value of water resistance in a phone is clear to anyone who's ever spilled tea, coffee or soda over their device. It can mean the difference between a quick wipe with a napkin and an expensive trip to the store. Not all phones can withstand a dunk in water, and some shouldn't be near liquid at all. Almost no phones should be taken swimming in a pool, and sea swimming is out of the question. If you've shopped for a phone recently, you'll have come across terms like "water resistant" and the now common IP67, IP68, or IPX8 ratings. But what do those ratings really mean and, crucially, how waterproof is your expensive new phone? IP, or ingress protection, ratings (aka international protection ratings) are a standard set forth by the International Electrotechnical Commission. According to the organization, the codes are designed as a "system for classifying the degrees of protection provided by the enclosures of electrical equipment." The first number in the rating code represents the amount of protection provided against the entry of foreign solid objects, such as fingers or dust. These protection levels range from a low of 0 to a high of 6. The second number represents the degree of protection against the entry of moisture or liquid, with protection levels ranging from a low of 0 to a high of 8. Sometimes you'll see an IP rating with a number replaced with an X, such as IPX8. In this instance, a company hasn't provided testing details so the rating number is replaced with an X. An IPX8-rated device can survive being submerged in water then, but it hasn't officially been rated for any protection from dust. The iPhone 14 Pro has an IP68 rating, meaning it's protected from dust getting inside and can withstand being submerged in water. The Galaxy S22 Ultra is also IP68 rated. So they're equally water-resistant, right? Well, no. That's where it gets confusing. For an 8 on the IP rating, the IEC demands a device can withstand being submerged in at least 1 meter of water for 30 minutes. Beyond that, it's up to the manufacturer. The S23 Ultra can be submerged in up to 1.5 meters of water for 30 minutes, while Apple says the iPhone 14 Pro is safe in up to 6 meters of water for up to 30 minutes. So while any phone with an IP68 rating will have had to hit that 1 meter-30 minute minimum threshold, it's important to check the fine print and see exactly what your phone offers.
