Overview
- Apple published the iPhone Duo product listing on Wednesday showing an IP68 dust and water rating and a footnote that the protection is not permanent.
- Apple says the rating was tested to IEC 60529 standards at up to 6 meters for 30 minutes and that resistance can decrease with normal wear.
- Google and Honor use similar factory-tested IP68 disclaimers for their foldables while Samsung’s current Galaxy foldables carry a lower IP48 rating.
- Foldable designs use hinges and moving joints that can break or shift seals over time and device repair or disassembly can further reduce water and dust resistance.
- The disclosures matter for buyers and repairs because a factory IP rating does not guarantee long-term waterproofing and teardowns and real-world tests will show how well these phones hold up.
