Sony: Don't use our waterproof phones underwater

Bad news if you were planning to take your
Xperia Z5 for a dip: 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.
. . Waterproofing has long been a key selling point
of the Xperia line, and the Z5 has the highest
possible IP68 rating for water and dust
resistance. That means it's been tested by being
immersed in fresh water for 30 minutes in
depths of up to 1.5 metres.
. . 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.

Making a splash

. . In other words, Sony can't guarantee that
swimming and snapping photos won't damage
your handset, because it didn't test the phone in
every possible scenario. It remains one of the
best handsets for waterproofing, however.
. . "There are... many environmental factors which
we could not assess [during testing]," explains a
Sony representative in a forum post. "Therefore
we recommend not submerging our Xperia Z5 in
water."
. . 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.
