Waterproof Cases: Ratings, Risks, and Real-World Use
Do waterproof cases actually work?
Yes—waterproof cases can keep water out when they are properly sealed and used within their stated limits. But “waterproof” is not a guarantee against every kind of exposure. A case’s protection depends on its rating, condition, fit, and how it is used.
What does a waterproof rating tell you?
Look for an IP rating, such as IP67 or IP68, rather than relying on a product description alone. The first digit refers to protection from dust; the second refers to water protection. An IP67 rating generally indicates protection during a brief, controlled immersion in fresh water up to 1 meter for 30 minutes. IP68 indicates immersion under conditions set by the manufacturer, so check the product’s stated depth and duration.
These ratings come from standardized tests, not a promise that a case will stay dry in every situation. Salt water, chlorinated pools, hot water, strong currents, and water pressure can create conditions different from those in a test.
Why can a waterproof case still leak?
Most leaks happen because the seal is compromised or the case is not closed correctly. Dirt, sand, hair, or lint around a gasket can leave a gap. A worn seal, cracked shell, damaged port cover, or loose closure can also reduce protection. Even a highly rated case may fail if it is dropped, exposed to chemicals, or used beyond its depth or time limits.
Before using a case near water, inspect its seals and follow the manufacturer’s instructions. Close every latch and port cover completely. If the maker recommends a test, try it with a dry tissue inside before placing an electronic device in the case. Recheck the case after impacts or repeated use.
How should you choose one?
Match the case to the device and the activity. A splash-resistant cover may be enough for rain or an accidental spill, while swimming or snorkeling calls for a case with an immersion rating and clear depth limits. Confirm that the case fits your exact device model; a poor fit can interfere with closures and seals. Never assume a waterproof sleeve or tablet cover is safe for submersion unless its specifications explicitly say so.

FAQ
Can you use a touchscreen through a waterproof case?
Often, yes. Many cases use a clear, flexible screen layer, but touch sensitivity can vary, and water droplets may interfere with taps. Check that the case is designed for your device and test the screen before relying on it.
