You Can Drop It in a Lake for 30 Minutes
The iPhone 12 series has an IP68 rating, which means it can withstand a decent amount of abuse before it starts to fail. The IP in IP68 stands for Ingress Protection, while the 6 indicates protection from particulates like sand and dust. For particulates, the highest rating is 6, and the iPhone 12 meets that level. The 8 is the waterproof rating, which is measured on a scale up to 9. If you drop your iPhone 12 into a lake, it can survive underwater for 30 minutes at a depth of up to 6 meters (20 feet). This beats the iPhone 11, which is water-resistant for 30 minutes up to just 2 meters. It also outperforms the iPhone 11 Pro series, which can go down to 4 meters before suffering water damage.
