Water resistance isn’t just a perk anymore; it’s a must-have feature for modern smartphones, especially for users of the latest iPhone models like the iPhone 17 Pro. If you’ve ever feared the chaos of a spilled drink near your device, you’ll appreciate how crucial this feature is. Today, many phones, from the iPhone 17 Pro to the Samsung Galaxy S25 Ultra, boast impressive water and dust resistance ratings that can save you from an expensive mishap.
Understanding IP Ratings: IP67, IP68, and IPX8
Two critical numbers define your phone’s ability to withstand water and dust – the IP rating. Established by the International Electrotechnical Commission (IEC), these ratings tell you how well your device is protected. The first digit indicates solid particle protection, and the second measures liquid resistance.
For example, the iPhone 17 Pro and Galaxy S25 Ultra both have an IP68 rating. This means they’ve passed stringent tests for dust protection and can endure water submersion. However, here’s the catch: while they share the same IP68 rating, the specifics differ. Apple asserts that the iPhone 17 Pro can be submerged 6 meters deep for 30 minutes, whereas Samsung states the Galaxy S25 Ultra can handle 1.5 meters for the same duration. It’s essential to know these details when considering your phone’s water resistance capabilities.
Swimming with Your iPhone: A Cautionary Tale
While your iPhone 17 Pro’s impressive 6-meter water resistance might tempt you to take it for a swim, think twice before you dive in. The IP testing happens under controlled conditions—meaning still water without any movement. Real-world conditions, like waves or splashes, can increase water pressure and lead to damage.
Moreover, saltwater and chlorinated water can be harsher than you might think. Salt can corrode the metal parts, especially those around your charging port. Consider the IP rating as more of a safety net for accidental spills or rain rather than a guarantee for underwater adventures.
What If My Phone Lacks an IP Rating?
If your device doesn’t sport an IP rating, it’s wise to treat it like a delicate flower around moisture. Many smartphones claim to be “water-repellent,” employing features like rubber seals or nano coatings. While these techniques provide some level of protection against splashes or light rain, they are not rated for full submersion.
Always best to err on the side of caution—protect your phone around liquids, and if it lacks an IP rating, keep it away from water as much as possible.
Solid Protection Ratings

|---|---|---|
| 0 | No protection | N/A |
| 1 | Protection from contact with any large surface of the body, such as the back of a hand. | Less than 50mm |
| 2 | Protection from fingers or similar objects | Less than 12.5mm |
| 3 | Protection from tools, thick wires or similar objects | Less than 2.5mm |
| 4 | Protection from most wires, screws or similar objects | Less than 1mm |
| 5 | Partial protection from contact with harmful dust | N/A |
| 6 | Protection from contact with harmful dust | N/A |
Moisture Protection Ratings
| IP Code | Protection | Test Duration | Usage |
|---|---|---|---|
| 0 | No protection | N/A | N/A |
| 1 | Protection against vertically dripping water | 10 mins | Light rain |
| 2 | Protection against vertically dripping water when tilted at an angle up to 15 degrees | 10 mins | Light rain |
| 3 | Protection against direct sprays of water when tilted at an angle up to 60 degrees | 5 mins | Rain and spraying |
| 4 | Protection from sprays and splashing of water in all directions | 5 mins | Rain, spraying, and splashing |
| 5 | Protection from low-pressure water projected from a nozzle with a 6.3mm diameter opening in any direction | 3 mins from a distance of 3 meters | Rain, splashing, and direct contact with most kitchen and bathroom faucets |
| 6 | Protection from water projected in powerful jets from a nozzle with a 12.5mm diameter opening | 3 mins from a distance of 3 meters | Rain, splashing, outdoor use in rough sea conditions |
| 7 | Protected from immersion in water with a depth of up to 1 meter for up to 30 mins | 30 mins | Rain, splashing, and accidental submersion |
| 8 | Protected from immersion in water with a depth of more than 1 meter (manufacturer specifies depth) | At least 30 mins | Rain, splashing, and accidental submersion |
