Just when you thought the Japanese device manufacturer was on the verge of a comeback, a key Xperia Z5-series selling point is stricken out, or at least radically diminished.
How cool is it to be able to take your smartphone with you everywhere, come rain or shine, in the desert, the wild outdoors, or even deep underwater, while swimming? It’s certainly special, not to mention the awesome photos that often result from submerging yourself alongside friends in a pool, sea or ocean.
But the ultimate authority in waterproof mobile gear seems to be sending mixed signals all of a sudden, advertising the Xperia Z5 Premium, Z5 and Z5 Compact as IP68 certified, yet at the same time advising against actually using the devices underwater.
For the record, the 8 in the IP68 rating should entail “equipment suitable for continuous immersion in water” beyond 1 meter. However, Sony insists laboratory testing conditions and real-life immersion aren’t the same thing, as Xperias get gently placed inside a container filled with tap water and lowered to a depth of 1.5 meters, then gently taken out after 30 minutes when validating the feature.
Two problems may appear while swimming and handling a 4K Z5 Premium, namely contact with seawater, salt water, or chlorinated water, as well as different speeds and levels of pressure applied at various depths.
Of course, your typical pool was filled with chlorinated water back when the Xperia Z2 or Z3 went official too, so what probably changed is Sony’s willingness to tackle damage caused by impure liquid interaction under standard warranty terms.
In other words, they want you to pay if you break an Xperia Z5, Z5 Premium or Z5 Compact, but also other theoretically water-resistant gadgets, while recklessly taking awesome pictures of your scuba diving tricks.
On the bright side, “singing in the rain” and “relaxing at the tub”, as well as washing off a dirty Xperia with tap water, should still be covered.
