Sony Xperia devices have been water resistant for a while now ad the company it’s very proud of that. Most of the recent waterproof Xperia smartphones and tablets come with the IP68-rating. This 6 translates into a dust-tight device, while the second digit – the 8 – means submersion into deeper than 1 meter clean water for 30 minutes or more.
The company has been reluctant to repair devices with liquid damage. In many cases the company said the damage resulted by some of the plastic caps not being tightly closed.
Now they are asking people not to use these devices underwater, despite the IP68 water resistance certification. These tests are made under laboratory conditions to achieve such a rating. The devices are gently placed under 1.5 meters of water for half an hour. When the users make fast movement underwater it places a lot of pressure on those seals and water may enter.
Probably Sony is dealing with a lot of warranty claims from people who have used the devices underwater. But maybe Sony should take a large part of the blame as it made the IP rating a key selling point for its devices.
