IP is the abbreviation for ingress protection, which means 'entry protection' or 'degree of protection'. IP indicates how well a device, such as a smartphone or sports watch, is resistant to dust and water. The first number is the protection against dust. It runs from 0 to 6. The second digit is the protection against water. It runs from 0 to 9, with 9 being completely waterproof. The higher the number of the second digit, the better protected your device is from water.
