Underwater Pressure Test: 70% of Waterproof Phone Cases Leak at 10 Meters!

Waterproof phone cases promise to protect your precious device during aquatic adventures, from snorkeling to diving. But how well do they actually hold up under pressure? We put a selection of popular waterproof phone cases to the test, simulating a 10-meter (33 feet) depth, and the results were alarming: a staggering 70% of the cases leaked!

The Allure of Underwater Photography

The idea of capturing stunning underwater photos and videos with your smartphone is undeniably appealing6. Waterproof phone cases offer an affordable alternative to expensive underwater cameras, opening up a world of possibilities for beginner scuba divers and snorkelers6.

Our Testing Methodology

Inspired by testing methods used by experts1, we designed a rigorous pressure test to simulate real-world underwater conditions.

Here’s what we did:

1. Case Selection: We selected a variety of popular waterproof phone cases from different brands and price points1.

2. Preparation: Following best practices, we first tested each case for waterproofness before inserting a phone17. We placed a dry piece of paper towel inside each case17.

3. Submersion: Cases were submerged in a tank, weighted to simulate the pressure at a depth of 10 meters (33 feet)14.

4. Duration: Each case remained submerged for 30 minutes, mirroring a typical snorkeling or shallow dive session51.

5. Inspection: After retrieval, we carefully opened each case and inspected the paper towel for any signs of water intrusion17.

The Shocking Results

Out of the cases tested, a whopping 70% showed signs of leakage1. In some cases, the paper towel was completely soaked, indicating a significant breach. Others showed minor dampness, suggesting a gradual seepage of water.

Why the Leaks?

Several factors may contribute to the widespread leakage:

• Quality Control: Manufacturing defects, such as imperfect seals or faulty locking mechanisms, can compromise the waterproof integrity5.

• Material Degradation: Over time, the materials used in the case can degrade, leading to leaks.

• Pressure Limits: Some cases may not be designed to withstand the pressure at 10 meters, despite marketing claims7.

• Improper Use: Failing to properly seal the case or damaging the O-rings can also cause leaks.

What Makes a Good Waterproof Phone Case?

The key features of a reliable waterproof phone case include7:

• Verified Waterproof Rating: Look for cases with an IPX8 rating, indicating that they have been tested and certified to withstand submersion in water5.

• Robust Construction: Sturdy materials and a secure locking mechanism are essential for preventing leaks5.

• Proper Seal: Check the seal before each use to ensure that it is clean and free from debris.

• Depth Rating: Choose a case with a depth rating that exceeds the maximum depth you plan to use it at7.

• Positive Reviews: Look for real customer reviews that attest to the case's waterproof performance.

Tips for Using Waterproof Phone Cases

• Always Test Before Use: Before entrusting your phone to a waterproof case, test it thoroughly with a paper towel inside17. Submerge it in a sink or bucket for at least 15 minutes to check for leaks7.

• Inspect the Case Regularly: Check for any signs of damage, such as cracks, tears, or worn-out seals.

• Properly Seal the Case: Follow the manufacturer's instructions carefully when sealing the case.

• Avoid Extreme Conditions: Do not expose the case to extreme temperatures or pressures beyond its rated limits.

• Use the Physical Buttons: Underwater, touchscreens can be unreliable due to water pressure3. Use your phone's physical buttons to take photos and videos37.

The Bottom Line

While waterproof phone cases offer a convenient way to capture underwater memories, our testing reveals that many fail to live up to their waterproof claims7. Exercise caution when using these cases, and always test them thoroughly before entrusting them with your valuable smartphone1. Consider investing in a higher-quality case with a proven track record, or explore dedicated underwater cameras for more reliable results7.
