Waterproof Phones Reviewed: Testing the Latest Models Underwater

Smartphones have become essential companions, and for many, durability is a top priority. Waterproofing is a key feature for users who want their devices to survive accidental spills, rain, or even a dip in the pool. In this blog post, we dive into the latest waterproof phone models of 2025, testing their claims under real-world underwater conditions. From flagship devices to mid-range contenders, we explore their performance, build quality, and underwater capabilities to help you choose the right phone for your aquatic adventures.

What Makes a Phone Waterproof?

Waterproofing in smartphones is typically measured by the Ingress Protection (IP) rating, such as IP68 or IP67. The first digit indicates dust resistance, while the second reflects water resistance. For example:

• IP68: Dust-tight and can be submerged in up to 1.5 meters of freshwater for 30 minutes.
• IP67: Dust-tight and can handle submersion in up to 1 meter of water for 30 minutes.

Manufacturers achieve this through sealed ports, water-resistant adhesives, and specialized coatings. However, saltwater, extreme depths, or prolonged exposure can still pose risks, so we put these claims to the test.

The Contenders

We selected three popular 2025 models known for their waterproofing claims:

1. Quantum X Pro (IP68)

   • Price: ~$1,200
   • Key Features: 6.8-inch AMOLED display, 50MP triple camera, 5,000mAh battery.
   • Waterproof Claim: Up to 2 meters for 30 minutes.

2. AquaPulse 7 (IP68)

   • Price: ~$800
   • Key Features: 6.5-inch OLED, 48MP underwater-optimized camera, 4,500mAh battery.
   • Waterproof Claim: Up to 1.5 meters for 30 minutes.

3. DuraTech Neo (IP67)

   • Price: ~$500
   • Key Features: 6.2-inch LCD, rugged design, 4,000mAh battery.
   • Waterproof Claim: Up to 1 meter for 30 minutes.

Testing Methodology

To evaluate these phones, we conducted a series of underwater tests in controlled environments:

1. Freshwater Submersion: Each phone was submerged in a tank of freshwater at the manufacturer’s specified depth and duration.
2. Saltwater Simulation: A mild saline solution mimicked ocean water to test real-world durability (with immediate freshwater rinsing to minimize corrosion).
3. Underwater Photography: We tested each phone’s camera performance underwater, capturing images and videos in a clear pool.
4. Post-Submersion Functionality: After each test, we checked for water ingress, touchscreen responsiveness, speaker clarity, and charging port functionality.

All tests were conducted with fully charged devices, and we followed manufacturer guidelines (e.g., ensuring ports were sealed).

Test Results

Quantum X Pro

• Freshwater Test: Survived 2 meters for 30 minutes with no issues. The touchscreen remained responsive, and speakers were clear post-submersion.
• Saltwater Test: Performed well after rinsing, with no visible corrosion or performance degradation.
• Underwater Photography: The 50MP camera delivered vibrant colors and sharp details, even in low-light underwater conditions. The dedicated underwater mode enhanced focus and color balance.
• Post-Submersion: All functions, including wireless charging, worked perfectly.

Verdict: The Quantum X Pro lives up to its IP68 rating, making it ideal for users who need a premium device for underwater activities.

AquaPulse 7

• Freshwater Test: Handled 1.5 meters for 30 minutes without issues. The touchscreen was slightly less responsive underwater but worked fine after drying.
• Saltwater Test: Minor speaker distortion post-test, but functionality returned after drying overnight.
• Underwater Photography: The 48MP camera, optimized for underwater use, produced excellent images with minimal distortion. Video stabilization was impressive.
• Post-Submersion: Charging port required thorough drying, but all other features worked flawlessly.

Verdict: A strong mid-range option with excellent underwater camera performance, though it requires careful drying after saltwater exposure.

DuraTech Neo

• Freshwater Test: Survived 1 meter for 30 minutes, as expected for IP67. The touchscreen was less responsive underwater compared to competitors.
• Saltwater Test: Showed slight water ingress in the charging port, requiring extended drying time. No permanent damage was observed.
• Underwater Photography: The camera struggled with focus and color accuracy underwater, producing grainy images in low light.
• Post-Submersion: Speakers sounded muffled until fully dried, but functionality was restored after 24 hours.

Verdict: The DuraTech Neo is a budget-friendly choice for basic water resistance but falls short in underwater photography and saltwater durability.

Key Takeaways

• Best Overall: The Quantum X Pro excels in all areas, offering robust waterproofing and stellar underwater photography for a premium price.
• Best Value: The AquaPulse 7 balances cost and performance, with a camera optimized for underwater use, making it great for casual adventurers.
• Best Budget: The DuraTech Neo is suitable for basic water resistance but isn’t ideal for frequent underwater use or photography.

Tips for Using Waterproof Phones

1. Check the IP Rating: Ensure the phone’s rating matches your needs (e.g., IP68 for deeper submersion).
2. Rinse After Saltwater: Always rinse the phone in freshwater after exposure to saltwater to prevent corrosion.
3. Dry Thoroughly: Use a dry cloth and let the phone air-dry before charging to avoid damage to ports.
4. Use a Case for Extra Protection: A waterproof case can enhance durability for extreme conditions.
5. Test Regularly: Over time, seals may weaken, so periodically test your phone’s water resistance.

Waterproof phones have come a long way, offering peace of mind for users who face wet environments. The Quantum X Pro stands out for its premium performance, while the AquaPulse 7 offers great value for underwater enthusiasts. The DuraTech Neo is a solid budget pick but requires extra care in harsher conditions. Before buying, consider your budget, how often you’ll use the phone underwater, and whether underwater photography is a priority. With the right choice, your phone can handle whatever splash comes its way.
