The IP67 rating is a combination of both water and dust resistance index. IP6x is the highest dust resistance rating and new iPhone models are completely protected against dust. Similarly, IPx7 means that the iPhone 7 and iPhone 7 Plus can withstand immersion in water to one meter (3.3 feet) for 30 minutes, tested in laboratory conditions. It is the second highest rating, below IP8, which indicates an ability to withstand long periods of immersion under pressure. Samsung’s devices are rated at IP68, suggesting better overall water resistance. “iPhone 7 and iPhone 7 Plus are splash, water, and dust resistant and were tested under controlled laboratory conditions with a rating of IP67 under IEC standard 60529. Splash, water, and dust resistance are not permanent conditions and resistance might decrease as a result of normal wear. Do not attempt to charge a wet iPhone; refer to the user guide for cleaning and drying instructions. Liquid damage not covered under warranty.” The above message seems to indicate that the iPhone 7 and the iPhone 7 Plus should be able to handle accidental drops in the shower, bathtub, pool, or light splashing. Also, it shouldn’t be used in high-pressure water situations, such as in direct shower water or a pressure washer, and it should not be left under water for a long period of time. Apple also warns against trying to charge a wet iPhone, which could result in damage to the device, and it specifies that any liquid damage to the device is not covered under warranty. So, as a cautionary measure, it is best to avoid contact of iPhone 7 and iPhone 7 Plus with water. In short, try and keep your smartphone safe and dry wherever possible.
