IP68 means the device is completely dust-tight (digit 6) and withstands continuous submersion in fresh water (digit 8), typically up to 1.5 meters for 30 minutes. Exact conditions can vary by manufacturer.

IP Rating: Definition & explanation
In a nutshell
IP rating indicates how well a smartphone is protected against dust and water ingress. It consists of two digits, such as IP68, showing dust and water resistance levels.
How does IP Rating work?
IP rating (Ingress Protection) is an internationally standardized system (IEC 60529) describing how well a device's housing resists solid particles and liquids. The first digit after IP indicates dust protection (0–6, with 6 meaning completely dust-tight), while the second indicates water protection (0–9, higher values allowing longer and deeper water exposure). For smartphones, IP68 is the current standard: dust-tight and protected against continuous submersion, typically up to 1.5 meters for 30 minutes. Some manufacturers also list IP69, indicating resistance to high-pressure and hot water jets. Importantly, these ratings come from controlled lab tests using fresh water. Saltwater, chlorinated water, or mechanical stress can compromise protection, and many manufacturers exclude water damage from warranty coverage despite IP certification. The rating also says nothing about scratch or impact resistance, which depend on separate factors like the display glass (e.g., Gorilla Glass). For consumers, IP rating is a key purchasing criterion, especially for beach use, sports, or humid environments like bathrooms.
Advantages of IP Rating
- Protects against rain and splashes
- Dust protection extends device lifespan
- Enables poolside or beach use
- Standardized, comparable values
- Reduces worry about accidental water exposure
Disadvantages of IP Rating
- No guaranteed protection against salt or chlorinated water
- Warranty often excludes water damage
- Protection can degrade over time
- Says nothing about drop or scratch resistance
- Lab test conditions may not reflect real-world use
Frequently asked questions
Usually not: many manufacturers explicitly exclude water damage from warranty despite IP certification, since tests occur under controlled lab conditions. Real-world factors like saltwater, soapy water, or drops before water contact are not covered.
Generally yes, a higher rating means better protection, but practically there's little noticeable difference beyond IP67 or IP68 for everyday use. What matters more is how realistic the test conditions match your actual use, such as swimming or showering with the device.
