Sony Does Not Recommend Using Cell Phone Underwater

We update the article with the official statement:

Sony Mobile statement on change in WP policy

“Sony Mobile is committed to providing the highest standards of product quality and customer service. Xperia models that feature levels of dust and water-resistance are validated independently and based on Ingress Protection (IP) standards agreed and used across the industry. We have every confidence in the qualities of Xperia devices, which are built to exacting technical standards and are designed to perform to high standards in normal usage.

“The recent changes to guidance we provide to our customers are designed to more clearly illustrate the best ways to protect devices in day-to-day usage. We communicate necessary precautions, and the specific parameters of ingress protection ratings, to help customers to protect their smartphones and tablets in line with the applicable warranty we provide.

“We have also recently updated our marketing visuals to better advocate sensible usage of our devices. The warranty terms provided for our products remain the same and any customer concerns will continue to be considered on a case by case basis in line with these terms.” says Phonejust.

One of the strengths of Sony Xperia Z series smartphone definitely affects the water resistance, not just a plus that allows you to use your Terminal so more “lighthearted” even in situations where other devices are likely to suffer a premature end (sea, pool, etc.). Even the new Xperia Z5, Z5, as the whole family of products offers this feature, reaching the high level of IP68 certification which guarantees the resistance of the terminal if immersed under a metre and a half of water up to 30 minutes.

Despite the certification specifications are clear, Sony has changed its policy regarding impermeability of its terminals, going to put special emphasis on the process by which the tests are carried out:

Remember not to use the device underwater. The IP rating of your device was achieved in laboratory conditions in standby mode, so you should not use the device underwater, such as taking pictures.

Sony devices that are tested for their waterproof abilities are placed gently inside a container filled with tap water and lowered to a depth of 1.5 metres. After 30 minutes in the container, the device is gently taken out and its functions and features are tested.

Moving or operating the device while it is submerged is not tested during the laboratory tests. There are also many environmental factors which we could not assess (e.g. water movement or water pressure changes during the movement), if a device is used underwater. Therefore we recommend not submerge our Xperia Z5 in water.

As you can see from the points mentioned by Sony support page and a review made by the same team of support, the Japanese manufacturer places special emphasis about the fact that the terminals are tested in a controlled environment, far different from using that you can do in the pool or in other scenarios more dynamic. What drives then Sony to specify these details, going so far as to advise against the use of the Terminal underwater? The reason for this must be sought in a bid by the producer of “putting a limit” to any warranty repairsbecause of water damage to Smartphones.

Specifying tighter conditions, Sony gets to shelter in case the device is different than the one you described, although this comes into conflict with the same advertising campaign carried out by the manufacturer in recent years, in which were shown various devices while taking pictures underwater and whatnot. All this can be confusing to those purchasers less careful they could swap the IP68 certification as an epitome of absolute guarantee against this damage.
