The realme Note 60x has an IP54 rating for dust and water resistance. This means it has some protection against dust ingress and can handle splashes of water.
While the IP54 rating offers protection against splashes, it's not designed for submersion in water. The phone should be able to withstand light rain or accidental splashes without damage, but you should avoid immersing it in water or exposing it to strong jets of water.
Realme itself highlights the IP54 rating as providing "worry-free" use against splashes. They also emphasize the "ArmorShell Protection" which contributes to the phone's overall durability and protects internal components from dust and water.
