Is the Galaxy S25 Ultra Waterproof? Tips for Extra Water Protection

Looking for a durable phone? Try the Galaxy S25 Ultra. Announced at Samsung’s Jan 2025 Galaxy Unpacked event, this premium flagship is 14 grams lighter than the previous model. However, it also features a strong titanium frame and Corning’s Gorilla Armor 2 – the first scratch-resistant, anti-reflective glass!

But alongside these durability features, is it waterproof? And how can you keep it properly protected against accidental drops? In this article, we’ll explain everything you need to know about the Galaxy S25 Ultra’s water-resistance rating and what that means for you.

Is the Galaxy S25 Ultra Waterproof?

No Galaxy phones are completely waterproof, including the S25 Ultra. Its IP68 rating means it can only survive certain levels of water exposure, including up to:

• 1.5 meters of fresh water 

• For up to 30 minutes

But that’s only if you follow the IP68 guidelines to keep your device safe around water: 

• Dry your phone thoroughly after it becomes wet

• Rinse any residue off after submersion

• Don’t use around the pool or at the beach 

• Avoid taking underwater photos, especially in salty or chlorinated water

What Does an IP68 Rating Mean?

The Galaxy S25 Ultra’s IP68 categorization refers to its ‘Ingress Protection’ rating. Developed by the International Electrotechnical Commission, this grading system measures an electronic device’s resistance to water and dust. 

Every rating comes with two numbers:

• First Number (0-6): Level of dust protection

• Second Number (0-9): Level of protection against liquids

A higher number indicates greater resistance to water and dust. This means the Galaxy S25 Ultra is completely resistant to small solid particles. And while the phone isn’t perfect in terms of water resistance, it’s pretty close! 

The OnePlus 15 is one of the only IP69-rated smartphones available. IP69 means it’s protected against high-pressure, high-temperature water jets when they’re applied from a close range – an unlikely scenario for a smartphone, anyway!

What to Do If Your Samsung S25 Ultra Gets Wet

Dry your Samsung S25 Ultra immediately if it becomes wet. (And avoid the old ‘life hack’ of putting it into a bowl of rice!)

Like all Samsung phones, the Ultra is designed to withstand everyday accidents, such as if it slips into the bath after an accidental drop or being caught in the rain, for instance. This means that it can handle getting slightly damp if you quickly follow these steps:

1. Immediately switch your S25 Ultra off to prevent any further water damage or short-circuiting. Remove your phone case to create room for moisture to escape. 

2. Thoroughly rinse your phone with fresh water first if it was exposed to sugary liquids or salty/chlorinated water. This stops chemicals from accumulating and blocking the ports.

3. Use a clean microfiber cloth to gently dry the phone. Focus on the charging port, external speakers, earpiece, microphone – any holes where moisture could infiltrate. 

4. Don’t forget to wipe the S Pen, either! Gently shake your S25 Ultra to remove any water from the S Pen slot. And ensure it’s dry before re-inserting the stylus!

5. Leave your device to air dry before turning it back on. Don’t make any calls until the phone is completely dry. The microphone can lower the volume of your voice on the other line.

Add synthetic desiccants to speed up the process. These drying agents come in small packets, often with electronics and leather goods like clothes and shoes. They contain beads of silica gel to absorb excess water. Pop your phone into an air-tight jar filled with the packets and wait for at least 24 hours!

What Not to Do If Your Galaxy S25 Ultra Gets Wet

Now you know exactly what to do in the event of moisture exposure, here are some things to avoid to stop your Galaxy S25 Ultra from becoming permanently damaged when it gets wet:

• Using a hair dryer

• Drying with a can of compressed air

• Blowing water out with your mouth

• Placing the phone in direct sunlight

• Exposing to excessive heat (which warps seals and internal components)

• Shaking excessively

• Pressing any buttons

• Charging or connecting a cable

• Making phone calls (or using your phone at all!)

How to Make the Galaxy S25 Ultra Waterproof

The best way to make your Galaxy S25 Ultra waterproof is by using a waterproof phone case.

The water and dust resistance of the S25 Ultra isn’t permanent, even with its IP68 rating. It can diminish over time due to:

• Natural aging

• General wear and tear

• Exposure to extreme weather or temperatures

These factors cause the seals and gaskets to deteriorate, leaving your phone more vulnerable to moisture.

And for the $1,299.99 starting price, you’ll want to protect this premium flagship for as long as possible. The solution? Ghostek’s Nautical phone case, which offers extreme waterproof protection for your Galaxy S25 Ultra.

The Nautical is built to survive in water up to 20 feet for as long as one hour, featuring a watertight portal seal. It also offers drop protection from up to 12 feet, while a secure hand grip and belt clip holster prevent accidents in the first place. This is crucial, as any physical damage, such as cracks or scratches, can also compromise your phone’s water-resistant capabilities.

Refined reactive buttons and precise detailed cutouts add extra functionality to this MagSafe-compatible case, along with S-Pen stylus access exclusively on the Ultra models.

Or, try the Nautical Slim. This phone case provides the same heavy-duty shockproof and watertight protection, but in a slimmer model. It features a scratch-resistant back and military-grade construction that’s submersible 6 feet underwater.
