Why do I need a waterproof case when my phone is already waterproof?

Most smartphones are water resistant , not necessarily waterproof, meaning they can handle short dunks in water, but nothing more. Companies like Apple and Samsung won’t offer warranty coverage on phones with any water damage. A waterproof case will offer much better water protection—often to 10 times more depth—and guard against drops, scuffs, and scratches.

Can I go scuba diving with a waterproof case?

The short answer is yes, provided you have a waterproof case certified to the depth you plan to dive—and how long you plan to be under. Many of the best waterproof cases are suitable for submersion in up to 100 meters of water, but you’ll want to read the fine print to see how long they’re designed to withstand that.

What do these IP ratings mean?

IP, or "Ingress Protection" codes, refer to how well an enclosure is sealed against foreign particles and moisture. They’re expressed by the letters “IP” followed by two numbers, such as "IP68." The first number represents how well a case is protected against solid particles like dust and dirt, while the second protects against water and other liquids. The higher each number, the better the protection. However, it’s important to note that the scale typically maxes out at IP68, which means a case is dust-tight and offers a minimum of protection against immersion in 1 meter of water for up to 30 minutes. This means that the level of protection provided by IP68 cases and enclosures can vary greatly, so always check the specific protection levels offered by each case.

What to Look For

Waterproof cases come in two general styles—those designed for specific smartphones and universal ones that can fit several models.

When buying a universal model, make sure that it fits your phone in size and works with all the necessary buttons, ports, and other functions you may want to use while it’s in the case.

If you plan to use a waterproof case while on vacation or a day at the beach, it’s handy to get one that also can replace your wallet by allowing you to store a few other essential items, such as the card key for your hotel room or a little emergency cash.

Finally, protecting your phone against deep water doesn’t help if you can’t get it back after it goes into the lake.

If you’re into activities like boating, kayaking, or rafting, look for a floatable case. These generally offer good depth protection, but you may never need that because your phone will float back to the surface.
