In today’s world, smartphones have become an essential part of our lives. We rely on them for everything from communication to entertainment to work. However, one downside of smartphones is their fragility – a short drop or splash of water can render them unusable. This is why waterproof phones have become so popular in recent years. But with so many options on the market, how do you know which phone is truly waterproof?
What does waterproof really mean?
When a phone is advertised as waterproof, it typically means it has an IP rating of IP67 or higher. The IP stands for Ingress Protection, and the rating is given on a scale of 0-9 for both dust protection and water protection.
For water protection specifically:
- IP67 means the device is dust-tight and can be immersed in 1 meter of water for 30 minutes.
- IP68 means the device is dust-tight and can be immersed in 1.5 meters of water for 30 minutes.
- IP69K means the device is dust-tight and can withstand high-pressure and steam cleaning.
However, it’s important to note that even within the same IP rating, the waterproof capabilities can vary between different phone models. The depth and time durations are theoretical lab tests – real-world performance may be different.
Factors that affect real-world waterproofing
There are a few key factors that determine how waterproof a phone will be in everyday usage:
- Depth of water exposure – Deeper water puts more pressure on the seals.
- Duration of exposure – Longer exposure times allow more water ingress.
- Water pressure – Running water, waves, etc. apply more force than still water.
- Water temperature – Colder water temps make rubber seals less flexible.
- Seal quality – Not all seals are created equal, even on IP68 phones.
In real-world use, your waterproof phone may not survive if you go beyond the IP rating’s test limits. For example, an IP67 phone may not last 30 minutes submerged in 1 meter of water if there are also waves and pressure pushing water into the seals.
Popular waterproof phone models
Here are some of the top waterproof phones on the market and how they stack up:
| Phone | IP Rating | Max Test Depth | Max Test Duration |
|---|---|---|---|
| iPhone 14 Pro | IP68 | 6 meters | 30 minutes |
| Samsung Galaxy S22 Ultra | IP68 | 1.5 meters | 30 minutes |
| Google Pixel 7 Pro | IP68 | 1.5 meters | 30 minutes |
As you can see, all three phones have the same IP68 rating. However, the iPhone 14 Pro has a significantly higher depth rating at 6 meters compared to 1.5 meters for the Samsung and Pixel. This suggests Apple has more confidence in the waterproofing capabilities.
Waterproofing design and construction
For a phone to be waterproof, every external opening must be sealed to prevent water ingress. Here are some common waterproofing methods used:
- Gaskets – Rubber gaskets around the SIM card slot and other openings.
- Adhesive – Waterproof adhesive seals the gaps between components.
- O-rings – Flexible O-ring seals fit into grooves and fill gaps.
- Mesh membranes – Waterproof mesh over microphones and speakers.
Additionally, waterproof phones need to maintain seal integrity while allowing access. This is often achieved using flip out trays or flaps for SIM and charging ports. The materials and quality of the seals are also very important for long-term waterproof effectiveness.
Should you use your phone underwater?
While waterproof phones can survive underwater use, it’s generally not recommended except for very brief periods. Prolonged underwater use raises the risk of exceeding seal ratings for both depth and time. The pressure and moisture can also impact mics and speakers over time.
Most manufacturers advise against intentionally submerging waterproof phones, only suggesting they will survive splashes, spills, rain, etc. Normal warranty policies do not cover water damage either.
For underwater use, a dedicated waterproof case designed for extended submersion is a better option. This adds significant protection without wearing down your phone’s own seals.
Maintenance tips for waterproof phones
To keep your waterproof phone in the best condition:
- Rinse the phone gently in fresh water if exposed to saltwater, chlorinated water, soaps, etc. residues can damage seals over time.
- Don’t open the SIM tray after wet use. Trapped moisture can escape into the phone when opened.
- Don’t plug in a wet charging port. Allow it to dry out completely first.
- Inspect seals periodically for damage or debris that could impair effectiveness.
- Avoid excessive drops, which can impact waterproofing integrity.
Warning signs of water damage
If your supposedly waterproof phone gets exposed to liquid, watch out for these signs of possible water damage:
- Condensation or fogging under the screen glass
- Blurry camera optics from trapped moisture
- Muffled or low speaker volume
- Glitchy or unresponsive touchscreen
- USB port not recognizing chargers
- SIM card not being detected
- Corrosion around ports, seams, or openings
If you notice any of these issues, discontinue use and dry out the phone thoroughly. Water trapped internally can lead to irreversible damage over time.
The best waterproof phone overall
Based on depth rating, construction, real-world tests, and manufacturer reputation, the iPhone 14 Pro stands out as the most waterproof phone currently available.
Key advantages of the iPhone 14 Pro include:
- Industry-leading IP68 rating with 6 meter maximum depth.
- Stainless steel construction with top-grade seals and gaskets.
- Repeated survival in challenging YouTube water tests.
- Apple support and warranty cover accidental water damage.
No other flagship phone combines such impressive lab results with excellent real-world, long-term water resistance. For anyone wanting a truly waterproof smartphone, the iPhone 14 Pro is the safest bet.
Runner-up: Galaxy S22 Ultra
The Samsung Galaxy S22 Ultra comes in a close second with its IP68 rating and excellent construction quality. It does not match the depth rating of the iPhone but has passed various rugged water challenges with flying colors.
Most affordable: Pixel 7a
Google’s budget-friendly Pixel 7a still provides IP67 water and dust resistance. For the price, its waterproofing capabilities are quite respectable though not on par with more expensive models.
Frequently asked questions
Can I use touchscreen underwater?
Most waterproof phones can be used normally underwater thanks to the touchscreen still working. However, visibility and screen responsiveness may decline at deeper depths.
Do I still need a case if my phone is waterproof?
Yes, a protective case is still recommended even if your phone is waterproof. Cases add shock protection to prevent damage from drops, since waterproofing does not make phones shatterproof.
How long does waterproofing last?
Waterproof effectiveness can degrade over time as seals wear out. Most waterproof phones maintain their protection for 2 to 3 years with proper maintenance. Eventually seals need replacement for continued water resistance.
Can I take pictures underwater?
Waterproof phones generally allow you to snap photos underwater with both front and rear cameras. However, image quality may not be optimized due to light distortion. An underwater camera is better for dedicated underwater photography.
Does waterproofing make a phone heavier?
Waterproof construction does add some weight due to internal reinforcements and thicker exterior sealants. However, with advancements in lightweight materials, most waterproof phones weigh only slightly more than non-waterproof versions.
Conclusion
When purchasing a smartphone today, waterproofing capability should be an important consideration. Accidental spills and dunks happen, and water resistance provides peace of mind that your phone will survive. IP67/IP68 ratings are the bare minimum you should accept.
While no phone is indestructible, the iPhone 14 Pro currently offers the best water protection based on ratings, real-world tests, and customer feedback. Just don’t go beyond the manufacturer ratings for depth and time when intentionally submerging your phone.
With proper maintenance and responsible use, a waterproof phone can easily give you years of use without liquid damage worries. So if you lead an active lifestyle or simply want insurance against accidents, choose your next phone wisely and look for the best water resistance for your budget.
