The new 2017 iPhones which include the iPhone 8, iPhone 8+ and the iPhone X are not waterproof. They are however water resistant (to a degree).
The iPhone X is rated IP67 under IEC standard 60529 much like the iPhone 8 and iPhone 8 plus models when it comes to water resistance. When you examine the tech specs for the new iPhone models you will find the small footnote that calls out the details of this.
As per Apple’s disclaimer via the footnote on the new iPhone Specs page:
“iPhone 8 and iPhone 8 Plus are splash, water, and dust resistant and were tested under controlled laboratory conditions with a rating of IP67 under IEC standard 60529. Splash, water, and dust resistance are not permanent conditions and resistance might decrease as a result of normal wear. Do not attempt to charge a wet iPhone; refer to the user guide for cleaning and drying instructions. Liquid damage not covered under warranty.”
It is important that you pay attention to this disclaimer. Liquid damage is not covered warranty.
Unlike the Apple Watch Series 2 and higher models, the iPhone models are not waterproof and you cannot swim wearing one.
Even the Apple Watch has certain limitations when using it for a swim workout.
Apple Watch Series 3 has a water resistance rating of 50 meters under ISO standard 22810:2010.
This means that it may be used for shallow-water activities like swimming in a pool or ocean.
However, Apple Watch Series 3 should not be used for scuba diving, waterskiing, or other activities involving high-velocity water or submersion below shallow depth.
What does the IP67 Rating mean on the iPhone?
A 7 rating ensures “ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1m of submersion)” according to the IEC.(International Electrotechnical commission).
In the IP67, the digit 6 stands for dust resistance and the 7 or the last digit is relevant for water resistance properties.
While a 7 rating on an iPhone 8 or iPhone X signifies protection for up to 30 minutes when the deviced is submerged upto 1m depth, The Samsung Galaxy Note 8 received an 8 certification for water resistance, meaning it can be underwater for 30 minutes at depths of up to 1.5m (5 feet).
This means that your iPhone 8 or iPhone X will not get damaged if it is exposed to a little rain splash while you are on a run. Likewise if you accidentally dropped it in the toilet or splashed some beer on it, you will be ok. Your iPhone will not be permanently damaged.
Apple’s iPhone does not feature hydrophobic coatings. This is a new feature with the Samsung phones since Samsung signed up an agreement with ORNL to provide this special coating that can “actively repeal liquid”. Again this feature makes the phone a little more water resistant but not entirely Waterproof.
If your new iPhone does get wet, it may be wise it wipe it clean with a dry cloth and wait till it dries up before you put your device on the wireless charger.
Remember They are Water-Resistant and not Water-Proof!! It pays to read the footnote.
