We’ve all had that heart-stopping moment: a spilled glass of water on the table or a sudden downpour while you’re holding your phone. While modern smartphones are more durable than their predecessors, technical jargon like “IP67” and “IP68” can be confusing, often leading users to overestimate exactly how much liquid their devices can handle.
Decoding IP Ratings: How to Read the Label
An IP (Ingress Protection) rating is an international standard (IEC 60529) that measures how effectively a device’s casing protects its internal components from foreign objects and moisture. The rating consists of two digits, each representing a specific level of protection:
- The first digit (0–6): Measures protection against solids, such as dust, dirt, and sand. A “6” is the highest possible score, indicating the device is completely dust-tight.
- The second digit (0–9): Measures water resistance. A higher number indicates the device can withstand greater pressure and deeper submersion.
It is crucial to remember that these ratings are determined under controlled laboratory conditions using fresh water. In the real world, your phone is more likely to encounter salt water, chlorinated pools, or sugary drinks—all of which are significantly more corrosive to a device’s seals than lab-grade water.
IP67 vs. IP68: What’s the Real Difference?
For iPhone users, two specific ratings define the limits of a device’s submersion capabilities:
- IP67: This rating means a device can survive being submerged in up to 1 meter of water for up to 30 minutes. This standard was introduced with the iPhone 7 series, marking Apple’s first major step toward official water resistance.
- IP68: This is a more robust standard, though the specific depth limits vary by model. While the IP68 baseline requires testing beyond 1 meter, Apple has engineered its latest models to withstand depths of up to 6 meters.
Despite these impressive specs, Apple notes that water and dust resistance are not permanent conditions. Protective seals can degrade over time due to normal wear and tear, accidental drops, or physical impact.
Water Resistance by iPhone Model
Apple has steadily improved its housing seals over the last several generations. To see how this technology has evolved over time, you can explore the history of iPhone models for a deeper look at generational shifts.
Depth ratings by model:
- Up to 6 meters (30 min): iPhone 12, 13, 14, 15, and 16 series (including Pro and Pro Max models).
- Up to 4 meters (30 min): iPhone 11 Pro and iPhone 11 Pro Max.
- Up to 2 meters (30 min): iPhone 11, iPhone XS, and iPhone XS Max.
- Up to 1 meter (30 min): iPhone 7, 8, XR, and the second- and third-generation iPhone SE.
Water Resistance and Refurbished iPhones
A common question is whether a refurbished iPhone remains as water-resistant as a brand-new one. The answer depends largely on the age and history of the device. Rubber gaskets and adhesive seals can dry out or lose their elasticity over time, which may reduce the device’s original protective capabilities.
At UPGREAT, every device undergoes a rigorous inspection by Apple-certified technicians. We specifically check Liquid Contact Indicators (LCI) to verify that the internal components have never been exposed to moisture. We do not sell devices with liquid damage. For more tips on what to look for when buying, see our guide on how to check the condition of a used iPhone before purchase.
Important Note: Apple’s standard warranty does not cover liquid damage. The same policy applies to refurbished devices; while UPGREAT provides a 2-year warranty, repairs for liquid damage are treated as a paid service. Think of water resistance as an “airbag” for accidents—it’s there for emergencies, not for intentional underwater use.
Common Risks Not Covered by IP Ratings
Even with a top-tier IP68 rating, your iPhone remains vulnerable to certain environments:
- Chemical Exposure: Soaps, shampoos, perfumes, sunscreens, and household cleaners can dissolve the water-resistant seals and strip the screen’s oil-repellent (oleophobic) coating.
- Steam and Humidity: Saunas and steam rooms are particularly dangerous. Hot steam is much smaller than water droplets and can easily bypass seals that would otherwise block liquid.
- High-Velocity Water: Activities like water skiing or using a high-pressure hose can force water past the seals, regardless of the depth rating.
- Salt Water: Ocean water is highly corrosive. If it dries inside ports or buttons, it leaves behind salt crystals that can cause permanent hardware failure.
What to Do if Your iPhone Gets Wet
If your device is exposed to liquid, take these steps immediately to prevent damage:
- Dry the exterior: Wipe the phone down thoroughly with a soft, lint-free microfiber cloth.
- Clear the ports: Gently tap the iPhone against your hand with the charging port facing down to remove excess liquid.
- Let it air out: Place the device in a dry area with consistent airflow. Wait at least 5 hours before attempting to plug it in or charge it.
- Avoid heat sources: Never use a hairdryer or heater to speed up the process. Excessive heat can warp the seals or damage the display.
- Skip the rice: The “rice bag” method is a persistent myth. Not only is it ineffective, but small grains of rice or dust particles can actually enter the ports and cause more harm.
If you believe water has bypassed the seals, it is best to have the device inspected by professionals. You can browse our full selection of iPhones to find a durable, modern device that fits your lifestyle.
