Ahoy there! Today, we're about to embark on a journey into the soggy world of smartphone IP ratings. "IP" stands for Ingress Protection (or International Protection) code. (Sometimes the IP ratings are humorously referred to as "I'm a Phone" ratings.) The IP rating is the secret sauce that determines just how much your phone can handle when it comes to dust, dirt, and a good ol' dunk in the water.
So, grab your snorkel, because we're diving headfirst into the watery depths of IP ratings!
IP Ratings Demystified
Let's start with the basics. An IP rating consists of two digits immediately following the letters "IP", as in "IP68", optionally followed by two letters (which you'll rarely see for a smartphone). The two digits are required.
The first digit, in this case, 6 (the highest it can go), refers to the phone's resistance against solid particles like dust and sand. The higher the number, the better the protection. If you've ever dropped your phone in the desert, you'll appreciate a high first digit!
Now, the second digit, 8 in IP68, is all about water resistance. This is where things get juicy (pun intended). The second digit ranges from 0 to 9, with 0 meaning "avoid water at all costs" and 9 meaning "this phone practically lives underwater". So, an IP65 phone can take a splash, while an IP69 phone could probably join a synchronized swimming team!
The letter "X" in place of any of these digits (as in IPX8) stands for an unknown or undisclosed value for the corresponding protection level. This is also used for describing one kind of protection independently of the other kind. The digit 0 means no protection is provided. We shall describe the digits in more details in the later sections.
Importance of Choosing a Suitable IP Rating When Buying a Phone
Choosing the right IP rating for your smartphone is a bit like picking the right shoes for a hike - it ensures your device is up to the task and can weather the elements you throw at it. Let's dive into why IP ratings matter when buying a smartphone:

Cracking the First Digit
Ah, the first digit of an IP rating, the guardian against solid intruders! The first digit, when not "X", can have a value from 0 to 6. Let's break down the different levels of protection it offers:
- IP0X: No protection - devices with this rating offer little to no protection against solid particles. Dust and dirt can waltz right in, and your phone won't even bat an eyelash. It's like inviting a tornado to your garden party - you're basically bringing your phone to a dust storm party, and it's not wearing a mask.
- IP1X to IP5X: Protection against larger objects, like accidental brushes with your morning pastry crumbs. As you move up from IP1X to IP5X, you're getting progressively better at keeping out the finer particles. Here are the sizes of the solid objects that the various values of the first digit provide protection against (from Wikipedia):
- IP1X: Effective against particles of size greater than 50 mm: Any large surface of the body, such as the back of a hand. But no protection against deliberate contact with a body part.
- IP2X: Effective against particles of size greater than 12.5 mm: Fingers or similar objects.
- IP3X: Effective against particles of size greater than 2.5 mm: Tools, thick wires, etc.
- IP4X: Effective against particles of size greater than 1 mm: Most wires, slender screws, large ants, etc.
- IP5X: Effective against dust: Ingress of dust is not entirely prevented, but it would not enter in sufficient quantity to interfere with the safe operation of the device.
- IP6X: Dustproof. Ah, the dustproof champion! No ingress of dust; complete protection against contact. A vacuum must be applied. Test duration of up to 8 hours based on airflow. In other words, your phone could hang out in a flour factory and come out unscathed, or it could practically moonlight as a vacuum cleaner without breaking a sweat. It's perfect for those dusty construction sites or desert adventures.
In a nutshell, the first digit of an IP rating sets the stage for how well your phone can fend off solid intruders. Whether you're dealing with sandy beaches, construction sites, or just the everyday mess of life, a higher first digit means your phone can keep its cool and stay protected from the gritty world outside.
To recap, a phone with a good first digit is like your device's superhero costume, ready to ward off dust and dirt with style!
Waterproofing the Second Digit
Time for the juicy water resistance scale. Let's uncover the watery secrets of the second digit in an IP rating:
- IPX0 - Stay Dry, Stay Safe: Avoid liquids like the plague. Your phone would rather not swim, even in a kiddie pool. A smartphone with an IPX0 rating is like a cat avoiding water - it wants no part of it. This phone won't withstand even the tiniest water droplets; it's as dry as the Sahara.
- IPX1 to IPX3 - Light Drizzles Welcome: Devices in this range can handle light drizzles and gentle splashes, but don't throw a water balloon at your phone. Think of it as your phone's way of saying, "I'll endure a sprinkle but don't throw me a pool party."
More details from Wikipedia (link previously given):
- IPX1: Effective against: Dripping water. Dripping water (vertically falling drops) shall have no unsafe effect on the specimen when mounted upright onto a turntable and rotated at 1 RPM. Test duration: 10 minutes. Water equivalent to 1 mm rainfall per minute.

Test duration: 1 minute per square meter for at least 3 minutes. Water volume: 100 liters per minute. Pressure: 100 kPa at a distance of 3 meters.
- IPX7 - Dive-In Delight: Dive in! IPX7-rated phones can be submerged in water up to 1 meter for 30 minutes. They're like the synchronized swimmers of the smartphone world, ready for the top performance. Poolside selfies, anyone?
More details from Wikipedia: Effective against: Immersion, up to 1 meter depth. Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 meter of submersion). Test duration: 30 minutes. Tested with the lowest point of the enclosure 1 m below the surface of the water, or the highest point 15 cm below the surface, whichever is deeper.
- IPX8 - Deep-Diving Adventurer: Diving champs! These phones are the diving experts, capable of surviving submersion beyond 1 meter, but for how long depends on the phones' specs.
More details from Wikipedia: Effective against: Immersion, 1 meter or more depth. The equipment is suitable for continuous immersion in water under conditions which the manufacturer shall specify. However, with certain types of equipment, it can mean that water can enter but only so that it produces no harmful effects. The test depth and duration are expected to be greater than the requirements for IPX7, and other environmental effects may be added, such as temperature cycling before immersion. Test duration: agreement with the manufacturer. Depth specified by the manufacturer, generally up to 3 meters.
- IPX9 - Deep-Sea Champion: These phones are the deep-sea explorers, even if there were to be a water heater in the depths of the sea. It's like having a phone with its own scuba gear.
More details from Wikipedia: Effective against: Powerful high-temperature water jets. Protected against close-range high-pressure, high-temperature spray downs. Smaller specimens rotate slowly on a turntable from 4 specific angles. Larger specimens are mounted in the intended position when used, no turntable required, and are tested freehand for at least 3 minutes at a distance of 0.15 - 0.2 meters. Test duration: Fixture: 30 sec. in each of 4 angles (2 min. total); Freehand: 1 minute per square meter, 3 minutes minimum. Water volume: 14 - 16 liters per minute. Pressure: 8 - 10 MPa at a distance of 0.10 - 0.15 meters. Water temperature: 80 °C.
- IPX9K - Wash-Down Appliacations: Details from Wikipedia: The IP69K rating is meant for high-pressure, high-temperature wash-down applications. IP69K rated enclosures must be both dust-tight (IP6X) and able to withstand high-pressure and steam cleaning. The test for IPX9K specifies a spray nozzle that is fed with 80 °C water at 8 - 10 MPa and a flow rate of 14 - 16 litres per minute. The nozzle is held 0.10 - 0.15 m from the tested device at angles of 0°, 30°, 60°, and 90°, for 30 seconds each. The test device sits on a turntable that completes a rotation once every 12 seconds (5 rpm). The IPx9 specification details a freehand method (described above) for testing larger specimens that will not fit on a turntable, which also requires at least one additional minute of spray time (1 minute per square-meter, 3 minutes minimum). The test distance also increases to 0.175 m (or 0.15 - 0.2 m).
So, the second digit of an IP rating is all about your phone's aquatic prowess. From avoiding water entirely to conquering the depths, each level tells you just how fearless your phone is when faced with water-related challenges. So, choose wisely, and you'll have a smartphone that's ready to make a splash (or not) in your life!
In any case, through, be careful about exposing your phone to a liquid other than pure water, as the rating does not specify protection against the chemical damage that such liquids can cause. Even the swimming pools could have chemicals poured into them for various reasons, chlorine being very common.
And of course, electricity and water do not mix; dry off your phone with a soft cloth before plugging it into a socket or connecting an accessory or another device to it.
Why a Smartphone is Sometimes Listed with Multiple IP ratings (as in IPX5/IPX7)
Ah, the multiple IP ratings mystery! It's like when you can't decide if you want to be a superhero or a ninja for Halloween, and end up wearing both costumes. Smartphones sometimes list multiple IP ratings because they want to cover all their bases and provide you with a complete picture of their capabilities in different scenarios.
When the same smartphone model has two different ratings that differ only in the second digit (as in IP68/IP65 of Sony Xperia 1 IV), it is because of the non-cumulative nature of the second digit beyond 6. Why? It's a bit like trying to explain why you can't stack pizzas to make a giant pizza.
When we say that the second digit of an IP rating from 7 onward is not cumulative of the previous digits, it means that each value of the digit represents a specific level of protection and isn't an accumulation of all the protections below it. Let us break it down:
- Second Digit from 0 to 6: In these cases, the second digit's protection is cumulative of all the levels below it. For example, if a phone has an IP64 rating, it's also protected against everything that the ratings IP63, IP62, and IP61 provide protection from.
- Second Digit from 7 Onward: Starting with the second digit of 7 and going up to 9, this digit represents water resistance independently of the values of the digit lower than 7. The tests for these higher digits are simply too different to compare with those for the digits 1 through 6.
In essence, when you see an IP rating with a second digit of 7 or higher, it's like evaluating the phone's water resistance capabilities on a separate scale. It doesn't rely on or accumulate protection levels from the lower values of the digit. So, if you're planning to take your phone for a swim, pay close attention to that second digit, and don't assume a value of 7 or higher automatically means the phone is equally adept at keeping out the splashes - it's a separate aquatic adventure altogether!
On the other hand, a phone might also list different IP ratings for its various models. Here's why this happens:
- Versatility: Smartphones are designed to be versatile and adapt to various environments. Listing multiple IP ratings allows manufacturers to communicate how well the device can perform in different situations. For example, a phone might have one rating for higher dust resistance, and another for higher water resistance, specifying which of the models is ready for wet and dry adventures.
- Comprehensive Protection: Some phones are engineered to provide comprehensive protection. By specifying different ratings, manufacturers show which of their models can excel in dusty construction sites or aquatic escapades. It's like having a brand that's a jack-of-all-trades when it comes to protection.
- Transparency: Manufacturers want to be transparent about their products' capabilities. Listing multiple IP ratings helps consumers make informed decisions by highlighting exactly what protection a phone model offers in various conditions. It's like giving you the full menu of your phone's superpowers.
- Marketing Flexibility: From a marketing perspective, multiple IP ratings can make a phone look even more appealing. It's like saying, "Not only can this phone handle dust like a pro, but it's also a water-resistant champ!" The various models cater to a broader audience with different needs.
- Specialized Testing: Sometimes, smartphones undergo separate testing for dust and water resistance. These tests may yield different results, leading to the assignment of distinct IP ratings for each aspect. It's like acing different subjects in school - you get individual grades for each one.
- Real-World Scenarios: Multiple IP ratings reflect real-world scenarios. While one rating might indicate resistance to dust and light splashes, another might signify the phone's ability to handle immersion in water. It's like telling a story where your phone is the hero facing different challenges.
When you see a smartphone with multiple IP ratings, don't be puzzled. It's the phone's way of saying, "I'm ready for anything!" You just need to choose your perfect model.
Optional Supplementary Letters in IP Rating
An IP rating may have supplementary letters following the digits described above (e.g., the letter "M" in the IP rating "IP65M"). These supplementary letters in IP ratings indicate additional, specialized protection for specific environmental conditions or mechanical tests.
Here's a breakdown of what each of these letters means and the types of the corresponding tests involved:
- F (Oil Resistant): This rating applies to devices that need protection from oil. To achieve this, the device must undergo tests where it's exposed to oils under operational conditions. These tests ensure that seals and materials won't degrade when exposed to lubricants or hydraulic fluids, making the rating especially relevant for industrial or mechanical environments.
- H (High Voltage Equipment): This letter is specific to devices used in high-voltage applications. Devices with this rating are tested to withstand the added stresses of high-voltage operation, ensuring that their seals and insulators don't compromise under voltage-specific conditions.
- M (Tested While Moving): Devices with the "M" rating are subjected to dust or water tests while parts are moving. This is particularly relevant for rugged smartphones, where it means that they were tested for protection against dust and water ingress while components (such as buttons or mechanical parts) were in motion. It's a stringent test that adds an extra layer of reliability for real-world use.
- S (Tested While Stationary): The "S" rating indicates that the device was tested for dust or water ingress while in a stationary position. This is common for devices that may not encounter much movement but still require protection against environmental exposure, like certain types of stationary industrial equipment.
- W (Weather Conditions): This rating is intended for outdoor devices that may be exposed to weather, particularly extreme temperatures or humidity levels. To meet this standard, the device must withstand prolonged exposure to environmental elements such as UV radiation, salt spray, or even extreme cold and heat, ensuring the materials remain durable.
An IP rating can carry multiple supplementary letters if the device is designed to meet several of these conditions. For example, an IP66MW rating would indicate that the device is dust-tight and resistant to powerful water jets (IP66) while meeting both "M" (tested while moving) and "W" (weather-resistance) standards. This would imply it can endure both dynamic testing (for example, protection while components are moving) and weather exposure, making it suitable for very rugged, outdoor environments where it could be exposed to both heavy movement and extreme conditions.
By adding these supplementary letters, manufacturers offer a clearer picture of a device's durability in specialized conditions, helping users pick models that meet their unique environmental needs.
Examples of Smartphones
Now that you're an IP rating guru, let's meet some smartphones with their waterproof superhero capes on:
- IPX7 - Google Pixel 6: Dive into Google's world with this waterproof beauty.
- IP67 - Apple iPhone 13: It can survive a coffee spill and a rainstorm while taking stunning photos.
- IP68 - Samsung Galaxy S22: Not only can it handle a swim, but it'll also snap pics of the fish!
- IP65M - Honor X9c: It can handle a fair amount of rough, active usage without compromising its dust and water resistance.
MIL-STD Standards: The Rugged Warrior's Handbook
Though less common than the IP ratings, you'll sometimes see an 'MIL-STD' standard applied to a smartphone. The United States Military Standards, also known as "MIL-STD", turn your smartphone into a rugged soldier, making it ready for the battlefield of everyday life. Let's dive into the world of MIL-STD, specifically focusing on the MIL-STD-810H standard, which is quite popular in the smartphone industry.

Frequently Asked Questions (FAQs)
What is an IP rating on a phone? What is an IP rating on a Galaxy phone?
The IP rating refers to "ingress protection" (or "international protection") code, which determines just how much your phone can handle when it comes to solids (read, dust and dirt) and water. An IP code consists of two digits immediately following the letters "IP", as in "IP68", optionally followed by two letters.
