Sony warns Xperia owners not to use its waterproof devices underwater


Advice comes despite the use of the smartphones underwater being central to manufacturers marketing

Sony has warned anyone owning an Xperia smartphone not to use it underwater, despite the feature being central to its marketing.

All of the latest versions of the Xperia range, the Z3, Z3+ and all models from the recently announced Z5 range – come with an IP68 rating, meaning they are water resistant in up to 1.5 metres for 30 minutes.

However, the manufacturer has made a dramatic u-turn, with a Sony representative explaining on a support forum that moving or operating the smartphone while underwater is not tested prior to their release.

“Our new Xperia Z5 is protected from water ingress according to the IPx5/x8 standard, which is the highest water protection featured in mobile handsets.

“The tests for this rating also include the slow submersion in a fresh water tank up to 1.5m for a duration of 30 minutes. 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.”
