The letter "Yo" refers to protection against dust and letter "P" refers to protection against liquids. In this case, the IP53 certification indicates that the Huawei P30 has a moderate level of protection against dust and rain.

the first digit "5" refers to dust protection, and means that the P30 is protected against the ingress of dust in harmful amounts, although it is possible that small amounts of dust could enter the device. the second number "3" refers to liquid protection, and means that the P30 is protected against rain or splashing water, but it is not designed to be submerged in water.

It is important to note that the IP53 certification does not guarantee complete protection against water and dust, and additional precautions are recommended to protect the device in extreme conditions.
