When buying a smartphone, durability is a top concern. Ingress Protection (IP) ratings, like IP67 and IP68, reveal how resistant a device is to dust and water. Understanding these ratings ensures your phone can handle your lifestyle.
Let’s explore the details of IP67 and IP68, their differences, and how to choose the best option for your needs.
What Are IP Ratings?
IP ratings consist of two digits:
- The First Digit: Measures protection against solid particles, like dust.
- A rating of “6” indicates the device is completely dust-tight.
- The Second Digit: Indicates water resistance.
- Ratings range from 0 to 9, where higher numbers mean better protection against water ingress.
IP67 Explained
- Dust Protection: Fully protected from dust, ensuring no particles can enter.
- Water Resistance: Can survive submersion in up to 1 meter of water for 30 minutes.
- Best For: Accidental splashes, rain, or brief immersion in water.
Devices with an IP67 rating are suitable for everyday users who don’t expose their phones to significant water risks.
IP68 Explained
- Dust Protection: Like IP67, it’s fully protected from dust ingress.
- Water Resistance: Can handle immersion beyond 1 meter, typically up to 1.5 meters or more for 30 minutes or longer.
- Best For: Swimming, water sports, or environments with frequent water exposure.
IP68 offers extra assurance for users who need their phones to withstand deeper or longer water exposure.
Key Differences Between IP67 and IP68
- Water Resistance Depth
- IP67: Up to 1 meter for 30 minutes.
- IP68: Beyond 1 meter, often up to 1.5 meters or more, depending on the manufacturer.
- Use Cases
- IP67: Everyday accidents, such as spills or rain.
- IP68: Deeper or prolonged submersion, ideal for water-intensive activities.
- Manufacturer Variations
- IP68 specifications can vary, so it’s essential to review the exact tolerances provided by the manufacturer.
Factors to Consider When Choosing
- Your Lifestyle
- Do you swim frequently or work in wet environments? Opt for IP68.
- Is accidental exposure your main concern? IP67 should suffice.
- Device Maintenance
- Even with an IP rating, regular exposure to saltwater, chlorine, or other liquids may damage your phone. Always rinse the device with fresh water and dry it properly.
- Long-Term Durability
- Wear and tear can reduce a phone’s water resistance over time. Handle your device carefully to maintain its protective features.
Limitations of IP Ratings
While IP ratings are valuable, they aren’t a guarantee of indestructibility:
- Freshwater Testing: Ratings are tested with fresh water. Exposure to saltwater or other liquids can cause corrosion or other damage.
- Wear and Tear: Drops, impacts, and prolonged use can degrade the protective seals over time.
- Warranty Caveats: Most manufacturers don’t cover water damage, even for IP68-rated devices.
Conclusion
Both IP67 and IP68 provide solid protection against dust and water. However, IP68 offers a higher level of water resistance, making it better suited for those who need extra assurance.
For general users, IP67 devices typically provide enough protection. Always review the manufacturer’s guidelines and consider your own habits when making a choice.
