Besides major upgrades such as 5G, new design or A14 Bionic chip, the iPhone 12 and iPhone 12 Pro generation are many other minor upgrades that Apple did not mention.
One of them is water resistance. Starting with iPhone 7 in 2016 with IP67 standard, Apple has continuously improved this index on recent iPhone generations. If the iPhone Xs in 2018 meets the IP68 standard, it allows this machine to survive underwater with a depth of 2 meters for 30 minutes; then to last year’s iPhone 11 Pro, this number was pushed up to 4m.
This year, Apple continues to break its own record. All four models are iPhone 12, iPhone 12 mini, iPhone 12 Pro and iPhone 12 Pro Max can “dive” at a depth of up to 6m in a period of 30 minutes. Relatively speaking, the water resistance of the iPhone 12 is 3 times better than the iPhone Xs (2m), and 6 times better than the iPhone 7 (1m).
iPhone 12 can be soaked in water at a depth of 6m for a period of 30 minutes
Again, a device will reach IP68 if it can pass the 1.5m water level test in 30 minutes. At this time, many people think that if the iPhone 12 reaches 6m, it will have to be “awarded the title” higher, such as IP68 + for example. However, in fact, the IP standard of iPhone 12 is still only IP68, similar to previous generations of iPhone Xs and iPhone 11 Pro.
So why Apple, although completely able to do so much better than the IP68 standard, has not voluntarily created other standards like IP68 + or IP68 Pro? Simply because standards are something that is born to be followed, not to be broken.
Apple can’t name the iPhone 12 a standard like “IP68 +”, although it does a lot better
If each manufacturer creates its own standard, then that standard is not the true “standard” anymore. What if Firm A creates the IP68 Pro standard, Firm B creates the IP68 + standard, Firm C creates the IP68 Ultra standard? End users will not know which standard is better than the one, breaking the original purpose of the “standard”.
In the case of IP standards, Apple is obligated to comply with the standards set by the IEC (International Electrotechnical Commission). And based on the conditions of this organization, although the iPhone 12 outperformed the minimum floor level of the IP68 standard, it was still classified as IP68.
The IP68 rating is higher than IP69K with additional temperature requirements. The product also has to pass the water level of 1.5m in 30 minutes, similar to the IP68 standard, but the temperature of the water must reach 80 degrees C. On the current market, there are not many smartphones meeting this IP69K standard.
