The Truth About Phone Waterproofing: What “IP68” Actually Means When Your Phone Gets Wet

Picture this.

You’re at the pool, your phone slips from your hand, splashes into the water, and your heart skips a beat.

Then you remember: Wait, my phone has an IP68 rating.

Instant relief.

But should you really feel that confident?

Modern smartphone marketing has created a common misconception that IP68 means “waterproof.” Many people treat their phones like underwater cameras, take them into showers, or assume they can survive any encounter with water.

The reality is far less dramatic and a lot more complicated.

An IP68 rating provides impressive protection, but it does not make your phone invincible. In fact, one misunderstanding about waterproofing is responsible for countless expensive repair bills every year.

Let’s unpack what IP68 really means and what happens when your phone gets wet.

The Biggest Myth: IP68 Does Not Mean Waterproof

The first thing to understand is that most smartphone manufacturers avoid using the word waterproof for a reason.

Instead, they use terms like:

• Water-resistant
• Water and dust resistant
• IP68 rated
• Ingress protection

That’s because no consumer smartphone is completely waterproof. An IP68 rating indicates a certain level of protection against dust and water under controlled testing conditions, not unlimited protection against every real-world water accident. Read more about waterproof or water-resistant phones.

Think of IP68 as a safety net, not a superpower.

Decoding the Meaning of IP68

The rating looks technical, but it’s actually quite simple once you break it down.

IP = Ingress Protection

The “IP” stands for Ingress Protection, an international standard used to measure how well electronic devices resist intrusion from dust and liquids.

The “6” Means Dust-Tight

The first number refers to protection against solid particles.

A rating of 6 is the highest level for protection against solid particles in the IP code and means the device is dust-tight. Dust, dirt, and sand should not penetrate the enclosure under testing conditions.

The “8” Refers to Water Resistance

The second number measures resistance to liquids.

An 8 indicates protection against continuous immersion in water under conditions specified by the manufacturer, although the exact depth and duration depend on the manufacturer’s testing specifications. Google’s Pixel technical specifications explain the limits of its devices’ water and dust resistance.

This is where things start getting misunderstood.

The Fine Print Nobody Reads

Most consumers stop reading after they see “IP68.”

Manufacturers don’t.

The exact test conditions matter.

One phone may be tested for:

• 1.5 meters of water
• 30 minutes of immersion

Another phone may be tested under different conditions altogether. Despite both carrying IP68 ratings, their specific limits are not always identical.

In other words, IP68 is not a universal guarantee.

It’s a category.

The details still matter.

Lab Water Is Not Real Life Water

This is where many expensive mistakes happen.

IP testing is typically conducted using controlled water conditions. Real-world environments often introduce factors that are not part of certification testing, including salt, chlorine, soap, and water movement.

That’s why these situations are very different:

The phone may survive all of them.

Or it may not.

The conditions are no longer the same as the laboratory environment used to earn the rating.

Why the Pool Is More Dangerous Than It Looks

People often assume that if a phone survives fresh water, it can survive a swimming pool.

Not necessarily.

Pool water contains chemicals.

Ocean water contains salt.

Both can be more aggressive than the water used during testing. Manufacturers warn that saltwater, chlorinated water, and other contaminants can leave residues, contribute to corrosion, and affect device components.

A quick accidental drop is usually one thing.

Regular underwater photography sessions are something else entirely.

The Problem Nobody Talks About: Aging

Water resistance is not permanent.

That’s perhaps the most important fact about IP68 devices.

Everyday wear can gradually reduce the effectiveness of protective seals and adhesives.

Factors that can affect water resistance include:

• Drops and impacts
• Device flexing
• Heat exposure
• Repairs
• Aging seals
• Normal wear and tear

Manufacturers note that water-resistant protections can diminish over time and after physical stress. Apple’s guidance on water resistance also explains that resistance can decrease with normal wear.

That brand-new phone on launch day may not have the same protection level two years later.

Why Manufacturers Still Won’t Cover Water Damage

Here’s a question worth asking:

If a phone is advertised with water resistance, why do many manufacturers still exclude liquid damage from standard warranty coverage?

The answer is simple.

Water exposure in the real world is unpredictable.

Manufacturers can verify how a device performed during testing.

They cannot reliably verify:

• The type of water involved
• The depth
• The temperature
• Previous device damage
• Aging seals

As a result, liquid damage is often excluded from warranty protection despite water-resistance ratings. Warranty terms vary by manufacturer, model, and region. Apple’s limited warranty information explains its coverage terms.

That fact alone should tell consumers how cautious they should be.

Why Showers Are Surprisingly Risky

One of the strangest misconceptions is that an IP68 phone is shower-safe.

Many manufacturers explicitly advise against using phones in showers, saunas, and steam rooms. High heat, humidity, and pressurised or high-velocity water create conditions that differ significantly from standard IP testing environments.

Steam and condensation can expose a phone to moisture under conditions it was not designed to withstand. Repeated exposure may also affect protective seals over time.

So yes, your phone may survive a rainstorm.

That doesn’t automatically make it shower-proof.

What You Should Do If Your Phone Gets Wet

If your phone comes into contact with water, the smartest response is surprisingly simple.

Do:

• Wipe the device with a soft cloth
• Remove visible moisture
• Let it dry naturally in a well-ventilated area
• Allow charging ports to dry fully

Don’t:

• Charge it immediately
• Blast it with a hair dryer
• Assume it is completely safe because of IP68
• Put it in rice

Several manufacturers recommend allowing the device to dry naturally and avoiding heat-based drying methods. Samsung’s guidance for wet Galaxy devices also advises against using heat to dry a phone. Do not charge the phone until it is completely dry.

Think of IP68 as Insurance, Not Permission

The smartest way to view water resistance is this:

IP68 isn’t a license to use your phone underwater.

It’s protection against accidents.

That’s a huge difference.

The rating is designed to help your phone survive certain types of accidental water exposure, such as:

• A sudden rainstorm
• An accidental spill
• A dropped phone near water
• Everyday environmental exposure

It’s not designed to guarantee safe, repeated underwater use.

The Bottom Line

IP68 is one of the most impressive durability features available on modern smartphones, but it has also become one of the most misunderstood. The rating means a device offers high levels of dust protection and water resistance under specific controlled testing conditions. It does not mean the phone is waterproof, immune to water damage, or guaranteed to survive every aquatic encounter.

The best way to think about an IP68 rating is as a safety feature rather than a lifestyle feature. It’s there to save you when accidents happen, not to encourage you to test its limits.

Because when it comes to electronics and water, the safest assumption is still the oldest one:

Your phone would rather stay dry.
