The value of water-resistance on a phone is clear to anyone who's ever spilled a pint of beer over a shiny new phone: It can mean the difference between a quick wipe with a napkin and a trip to the Apple store. While waterproofing used to be something found only on those beefy, rubber-sealed rugged phones designed for construction workers or downhill mountain bikers, now you'll find it built -- to differing extents -- into most mainstream phones, including the, and the new and .
But not all phones can withstand a dunking, and some should avoid being near water altogether. If you've shopped for a phone recently then you'll have come across terms like "water-resistant" as well as the now common IP67, IP68 or IPX8 ratings. But what do those ratings really mean and, crucially, how waterproof is your expensive new phone?
Let's break down the jargon and find out.
What does IP67, IP68 and IPX8 mean?
IP, or ingress protection ratings (also known as 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 degree 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 through 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 then can survive being submerged in water, but it hasn't officially been rated for any protection from dust.
The iPhone 13 Pro, for example, has an IP68 rating, meaning it's protected from dust getting inside and can withstand being submerged in water. The Galaxy S21 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 S21 Ultra can be submerged in up to 1.5 meters of water for 30 minutes, while Apple says the iPhone 12 Pro Max is safe in up to 6 meters of water for up to 30 minutes. So while any phone with an IP rating will have had to hit the minimum threshold, it's important to check the fine print and see exactly what your phone offers.
For further details of all the IP ratings, you can see charts at the end of this article that outline all of the protection levels set by the IEC.
Can I go swimming with my iPhone?
While the iPhone 13 Pro's advertised 6 meters of water-resistance might make it seem like you can slip one into your swim shorts and hit the pool, you'd be well advised to leave it out of the water. The IP rating is tested in controlled conditions, in water with no movement. Moving your phone in the water will add more water pressure, making it more likely that water could find its way in and do irreparable damage to your phone.
The IP tests are also done using fresh water. Most pools will have additional chemicals such as chlorine, which could make a difference to your phone's resistance. And you should absolutely keep your phone out of the sea. That salt water could cause a lot of trouble, including degrading the metal parts in your charging port.
Even if your phone has the top IP68 resistance rating, it's still good practice to treat the feature as a backup in case of emergencies. Your phone is not designed to go snorkeling, so don't try using the camera to snag pictures of starfish or whatever. Nor should you try to recordvideos of yourself jumping off the high dive into the deep end. It's there for accidents like spilling a drink or emergencies like making a call in the pouring rain.
My phone doesn't have an IP rating. Can it get wet?
In order for a company to advertise that their product has an IP rating at all, it needs to have undergone strict tests to ensure it meets the requirements. These tests can be both timely and costly, so it's understandable that some companies simply don't want to spend the cash, particularly when it comes to more budget-focused models.
Some phones -- including Motorola's Moto G50 -- use terms like "water-repellent" or "water-resistant" without an official IP rating. These handsets may make use of methods like rubberized seals or water-repellent nano coating to keep moisture at bay. While these phones may well survive an accidental dunking, it's worth keeping them safe from being fully submerged in water. But you shouldn't need to worry too much about taking calls in the rain.
If your phone makes no mention of water resistance then it's best to assume that there isn't any and that you should take as much care as you can around liquids.
