What is a Water Proof Smart Phone and Why Does it Matter?


You quickly realise the importance of a water proof smart phone when you drop the handset in a river, rock pool or toilet bowl. But, before you buy one, make sure you understand the difference between resistance and proof. In this article, we give you a run-down on the difference, the importance of the IP rating, and where you can buy the perfect outdoor mobile handset.


What is a water proof smart phone?


It’s a mobile handset, specifically designed to protect the components from damage related to water exposure.    Resistance differs from water proof. The handset can have features to prevent small droplets from entering the casing where the screen is connected to the casing. Although a great feature, it doesn’t protect the handset from fluid penetration if submerged, as might be the case when you drop it in the sink, bath or pool. With the latter, the handset can be submerged as the enclosure provides adequate fluid protection.



Why does it matter, and why should you buy one?


For the most part, we have become used to protecting our mobile handsets against spillage and taking care not to drop them in the toilet bowl, but accidents do happen. Given the cost of these handsets and the frustration to replace or repair them once damaged, buying a device with built-in protection makes life easier and reduces the risk of having to spend more money to maintain its operation.


How do you know the handset is water proof?


The proof is in the rating. The International Electrotechnical Commission (IEC) gives an ingress protection (IP) rating to state the degree to which the electrical components inside the enclosure of a device are protected. The enclosure is the key here. The rating works as follows:


  • The first number from 0 to 6 shows the level of protection against foreign particle entrance, including dust, debris and even fingers.
  • The second number shows the level of protection against liquid penetration, rated 0 to 8.


This means a handset with an IP68 rating has the ultimate protection of its electrical components. You’re likely to see IP67 and IP68 ratings for a water proof smart phone. For it to qualify for IP68, the handset must be able to withstand fluid penetration if submerged. For a rating of 8, the handset can withstand fluid penetration for up to 30 minutes at a depth of not deeper than one metre. However, if it can be submerged deeper, the manufacturer will state it.


Does this mean you can swim with your handset?


Yes, if you are snorkelling and want to take pictures from the surface of the water. Otherwise, you can use it to take photos by just submerging it under the surface. Keep in mind, home swimming pools have loads of chemicals. The IP rating is for water immersion and protection, not harsh chemicals. It’s best to keep the handset out of your swimming pool, but if dropped or used in the pool, rinse it off with clean water to remove chemical residue on the enclosure.
