Many of the Xperia™ smartphones are waterproof and protected against dust, so don’t worry if you get caught in the rain or want to wash off dirt under a tap, but remember: all ports and attached covers should be firmly closed. You should not: put the device completely underwater; or expose it to seawater, salt water, chlorinated water or liquids such as drinks. Abuse and improper use of device will invalidate warranty. The device has Ingress Protection rating IP65/68. For more info see Water and dust protection – all you need to know – Sony support (English). Note that some have a capless USB port to connect and charge. On these, the USB port needs to be completely dry before charging.
