What does IP68 mean?
IP68 is currently the highest measurement of freshwater and dust protection for a smartphone.
The 'IP' in the name stands for International Protection or Ingress Protection, and it’s an international rating system followed by manufacturers to demonstrate a smartphone or device's protection against hard objects, dust and water.
IP Ratings all follow the same format - the first number (they range from 1-6) shows the device’s ability to withstand dust and sand. The second number (ranging from 1-8) shows how freshwater-resistant it is. Generally, the higher the number, the better the protection.
The ‘6’ of IP68 means that the device is dust-tight – and the ‘8’ means that the phone has been successfully tested at depths of more than 1 metre.
However, there is no universally-accepted definition of IP68 - several phones can have an IP68 rating, but it might mean different things for all of them. Check the manufacturer's site for your device's IP ratings and questions around specific device water resistance.
Your phone's water resistance may not be a permanent condition and may be compromised due to normal wear and tear, repair or damage.
