Nothing is 100% waterproof. I wouldn't believe that for a minute.
Below is the exact wording for IP ratings for liquids (applies to the last digit so the "8" in "68" for example). Notice it says nothing about "Only in lab conditions when the device is les than37 minutes old." Yeah, if you crack the screen, expect a decrease in water resistance. If you bend the phone, you might damage a seal. An intact phone rated to IP68 should be able to withstand IP68 conditions. It isn't rocket science.
Anything else is bait and switch. "The car was red until you bought it. Now it is rated as green in color," sound stupid to you? This phone was IP68 until you opened the box, now it is IP60. Same thing.
Sheesh, its like Shrodingers Water Protection: The phone is 100% waterproof until it gets wet.
Ingress Protection (IP) and what it means
The IP Code (or
International Protection Rating, sometimes also interpreted as
Ingress Protection Rating*) consists of the letters IP followed by two digits and an optional letter. As defined in international standard IEC 60529, it classifies the degrees of protection provided against the intrusion of solid objects (including body parts like hands and fingers), dust, accidental contact, and water in electrical enclosures. The standard aims to provide users more detailed information than vague marketing terms such as waterproof.
The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. For example, an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. IP22 or 2X are typical minimum requirements for the design of electrical accessories for indoor use.
0 | Not protected | – |
1 | Dripping water | Dripping water (vertically falling drops) shall have no harmfull effect. |
2 | Dripping water when tilted up to 15° | Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle up to 15° from its normal position. |
3 | Spraying water | Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect. |
4 | Splashing water | Water splashing against the enclosure from any direction shall have no harmful effect. |
5 | Water jets | Water projected by a nozzle (6.3mm) against enclosure from any direction shall have no harmful effects. |
6 | Powerful water jets | Water projected in powerful jets (12.5mm nozzle) against the enclosure from any direction shall have no harmful effects. |
7 | Immersion up to 1m | 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 1 m of submersion). |
8 | Immersion beyond 1m | The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. Normally, this will mean that the equipment is hermetically sealed. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects. |
