Despite all the adverts, Sony has admitted that its Xperia Z5 smartphone is not exactly waterproof.
In a change to its guidelines for the device, Sony says you shouldn’t take the device underwater, and you’ll void its warranty if you do.
This might strike you as a little odd–waterproofing has long been a key selling point of the Xperia line and the Z5 has a high IP68 rating for water and dust resistance. To get this rating it has been tested by being immersed in fresh water for 30 minutes in depths of up to 1.5 metres. More than enough to make sure it survives being dropped in a loo or a sink.
However, the language used on Sony’s website has changed: “The IP rating of your device was achieved in laboratory conditions in standby mode, so you should not use the device underwater,” the new policy says.
What this means is that Sony cannot guarantee that swimming and snapping photos will not damage your handset, because it did not test the phone in every possible scenario. It remains one of the best handsets for waterproofing, however.
The updated guidelines apply to all three models of the Xperia Z5 and you can read them for yourself on the official Sony website. “You should not put the device completely underwater or expose it to seawater, salt water, chlorinated water or liquids such as drinks,” it says.
