If you’re a fan of browsing in the bath or photography by the pool, a water-resistant phone can help to give you peace of mind that your phone has been designed to survive the odd spill, splash or dunk. It might also offer protection against bad weather.
The first thing to know is that many smartphones these days are classed as water resistant - phones aren't designed to be underwater, but water resistance is a protective feature in case they do end up being submerged. There will be limitations to how long a device is able to withstand being submerged in water or exposed to other elements, so it’s always best to check the manufacturer’s site for a device’s water resistance protection. It’s worth bearing in mind that water resistance is not a permanent condition and may be compromised due to normal wear and tear, damage or any repairs.
What's the difference between waterproof and water-resistant phones?
Water-resistant
Water-resistant phones have been designed to resist water penetration to some degree. They’re designed to make it hard for water to get inside, and they may be coated with a water-resistant substance which helps to keep water out. Water-resistant phones may be able to cope with splashes, light rain, showers, or a very quick submersion in fresh water.
Waterproof
Waterproof phones could be submerged in water for a period of time - but there’s no such thing as a totally waterproof phone which will survive being in water indefinitely.
If you want a phone with the highest level of waterproofing, choose one with an IP67 or IP68 rating. IP67 means the phone is designed to withstand being in water 1 metre deep for 30 minutes, and while IP68 doesn’t have an exact universal depth guide, phones given this rating have been tested at depths more than 1 metre.
IP68 rated phones
Examples of phones with an IP68 rating include:
- Samsung Galaxy S22 Ultra, Galaxy S22+ and Galaxy S22 can be submerged to a depth of 1.5 metres for up to 30 minutes. This is based on test conditions for submersion in up to 1.5 metres of freshwater for up to 30 minutes. The Galaxy S22 series is not advised for beach or pool use.
- Samsung Galaxy S21 5G can be submerged to a depth of 1.5 metres for up to 30 minutes. This is based on test conditions for submersion in up to 1.5 metres of freshwater for up to 30 minutes. The Galaxy S21 series is not advised for beach or pool use.
- Samsung Galaxy S21 FE can be submerged to a depth of 1.5 metres for up to 30 minutes. The Galaxy S21 FE is not advised for beach or pool use.
- Samsung Galaxy S20 FE 4G can be submerged to a depth of 1.5 metres for up to 30 minutes. This is based on test conditions for submersion in up to 1.5 metres of freshwater for up to 30 minutes. The Galaxy S20 FE series is not advised for beach or pool use.
- Google Pixel 6 Pro and Pixel 6 can be submerged to a depth of 1.5 metres for up to 30 minutes. They’re designed to comply with water protection rating IPX8 under IEC standard 60529 when each device leaves the factory, but the devices are not waterproof. Their accessories are not water resistant. Water resistance is not a permanent condition, and diminishes or is lost over time due to normal wear and tear, device repair, disassembly or damage. Dropping your device may result in loss of water resistance. Liquid damage voids the warranty.
- OPPO Find X5 Pro 5G an be submerged to a depth of 1.5 metres for up to 30 minutes. The IP68 rating means that the product has passed the test under the following conditions: (1) immersed in still fresh water with a depth of 1.5 metres; (2) tested for 30 minutes; (3) no more than 5°C of difference between the water temperature and product temperature.
- OPPO Find X3 Pro can be submerged to a depth of 1.5 metres for up to 30 minutes. The IP68 rating means that the product has passed the test under the following conditions: (1) immersed in still fresh water with a depth of 1.5 metres; (2) tested for 30 minutes; (3) no more than 5°C of difference between the water temperature and product temperature.
- Sony Xperia 10 III has an IP65/68 rating - it’s water resistant and protected against dust. This phone has a capless USB port to connect and charge, and the USB port needs to be completely dry before charging. It also shouldn’t be put completely underwater.
IP67 rated phones
IP67-rated smartphones include the Samsung Galaxy A53 5G and the Samsung Galaxy A52s 5G.
This rating is based on test conditions of submersion in up to 1 metre of freshwater for up to 30 minutes - which differs to the 1.5 metre freshwater depth testing of IP68-rated devices.
Samsung advises to rinse off any water residue or dry your device if it gets wet. Samsung devices are not advised for beach or pool use and may not be water resistant if submerged in soapy water.
What are IP ratings?
IP stands for International Protection or Ingress Protection, and it’s an international standard followed by manufacturers. An IP rating starts with ‘IP’, and is followed by two numbers.
The first number of an IP rating shows how resistant the device is to solids, such as dust. The number ranges from 0 to 6 - the higher the number, the better the protection. A device with a 6 as the first number is completely protected against contact with dust.
The second number refers to freshwater resistance, with numbers that range from 0-9. The higher the number, the better the level of water protection.
IP rating | Definition for solids | Definition for liquids |
|---|---|---|
| X | Not tested | Not tested |
| 0 | No protection | No protection |
| 1 | Protection from solid objects over 50mm (e.g. accidental touch) | Protection from falling water, such as rain |
| 2 | Protection from solid objects over 12mm (e.g. fingers) | Protection from direct sprays up to 15° from vertical |
| 3 | Protection from solid objects over 2.5mm (e.g. tools) | Protection from direct sprays up to 60° from vertical |
| 4 | Protection from solid objects over 1mm (e.g. wires) | Protection from spray from all directions |
| 5 | Protection against dust - dust cannot easily enter | Protection from low-pressure water jets |
| 6 | Total dust protection – dust cannot enter the device | Protection from high pressure water jets |
| 7 | n/a | Can be immersed between 15cm - 1m for 30 minutes |
| 8 | n/a | Protected against long periods underwater |
| 9 | n/a | Protection from close-range high pressure, high-temperature water jets |

Budget water resistant phones
Most budget phones currently in the market are unlikely to offer protection if they were to be submerged in water. Many phones are designed to be water repellent against the odd surface splash, spill or light rain, but do not offer the water resistance protection of a higher end device with an IP67 or IP68 rating.
Rugged phones
Rugged phones are water resistant, and they’re designed to withstand shocks, challenging terrain and extreme weather conditions. Phones with a MIL-STD-810G rating are guaranteed to have a very high level of durability - they’ve been through a rigorous series of tests in hostile environments, including heat, cold, shock and humidity. They also tend to have a high IP rating - for example, the Cat B35 has been given an IP68 rating as it’s water-resistant in up to 1.2 metres of freshwater for up to 35 minutes.
What’s the difference between water resistance and dust resistance?
A device can be totally dust resistant - any phone with an IP rating which starts with a 6 is totally protected against dust. However, even phones with an IP68 rating - the highest current rating for a smartphone - can be damaged by water if submerged for long enough.
Can waterproof phones be submerged in seawater or pool water?
No - phones given the highest IP rating are only tested in fresh water in lab conditions. That means you’re not guaranteed protection from submersion in other liquids, such as alcoholic or soft drinks, chlorinated water or seawater.
Can I take underwater pictures with a waterproof phone?
We wouldn’t recommend using your phone to take underwater pictures in pools, the sea, or fresh water. If you want to take underwater pictures, you need to buy a protective pouch or a hard shell case with a watertight seal for your phone.
Even waterproof phones with an IP68 rating have a limit to the time they can spend underwater and the depths they can manage, so a case can help provide added protection.
