In the current scenario, here are some commonly found IP ratings and their meanings:
IP67: Protected from dust and water immersion up to 1 meter deep for 30 minutes.
IP68: It offers better protection, which is safe up to 1.5 meters of water depth and can protect the device for 30 minutes.
IP69: This is the highest rating available currently, and it can withstand high-pressure water jets and deep submersion, which helps the device last longer.
Smartphones with IP68 or IP69 ratings are considered truly waterproof and dustproof. Many flagship smartphones like iPhone 15, Samsung Galaxy S24, and some premium budget handsets also support these ratings.
