At the presentations of Xperia waterproof devices Sony usually drew attention to underwater usage of the devices. Xperia phones were advertised with press photos showing people taking selfies underwater and the phones thrown into the water, which indirectly suggested that you can actually do those things. However Sony’s website has issued a warning to its users not to use their devices underwater.
Most of Sony’s waterproof devices are IP68-certified. It means they’re protected against the damage effects of water at depths not greater than 1.5 m within 30 min. Now Sony claims that the devices were tested in the laboratory conditions when the phones were accurately submerged into clean water straight 1.5 m deep and took out of water in 30 min sharp. A departure from these parameters can cause hit of water into the device.
In other words, advertising images shouldn’t be taken literally. If you are going to jump into a chlorine-laden pool or throw the handset into salty seawater, be ready that Sony can refuse to repair or replace the damaged handset. In case the device accidentally gets into wet with non-fresh water, Sony advices to wash it with tap water.
Moreover Sony’s website cautions that improper use of the Xperia Z5 device will invalidate warranty. Under “improper use” is understood a full immersion or exposing the device to seawater, salt water, chlorinated water, or liquids such as drinks.
What forced Sony to change its waterproof policy? Probably the reason is the increased number of warranty service requests.
