The iPhone 17, like its recent predecessors, comes with an IP68 rating under the IEC standard 60529, meaning it is designed to withstand submersion in fresh water up to 6 meters deep for 30 minutes under controlled laboratory conditions. However, this rating does not guarantee immunity to all types of water exposure, especially saltwater or chlorinated pool water, which pose distinct risks to the device.
Saltwater Exposure Risks
Saltwater is highly corrosive and can severely damage the iPhone 17’s internal components over time. The salt can degrade the phone’s seals, allowing water ingress that leads to corrosion of the logic board and other sensitive electronics. Salt deposits left behind after evaporation are conductive and can cause short circuits, potentially rendering the device permanently inoperable. Even with the iPhone’s water resistance, Apple explicitly advises against intentional submersion in seawater, as the warranty does not cover damage caused by water, particularly saltwater corrosion[1].
Chlorinated Pool Water Risks
Chlorinated water, while less corrosive than saltwater, still presents a threat to the iPhone 17. The chemicals in pool water can degrade the waterproof seals over time, increasing the risk of water damage with repeated or prolonged exposure. Although brief splashes or accidental drops in a pool may not immediately harm the device, regular or deep submersion in chlorinated water is not recommended. Damage from such exposure is cumulative and can compromise the water resistance of the phone[1].
Practical Considerations and Protection Tips
- Avoid intentional submersion: Despite the IP68 rating, the iPhone 17 is not designed for intentional underwater use, especially in harsh environments like the sea or chlorinated pools.
- Use a waterproof case: For those who frequently bring their iPhone near water, a robust waterproof case (e.g., OtterBox Defender) provides an extra layer of protection against water ingress, including saltwater[2].
- Rinse after exposure: If the iPhone accidentally contacts saltwater or chlorinated water, rinsing it gently with fresh tap water can help dilute corrosive residues and reduce damage risk.
- Turn off immediately if submerged: If the phone is submerged, power it off immediately and avoid using it until thoroughly dried to prevent short circuits.
- Regular backups: Since water damage is not covered under Apple’s warranty and can cause total data loss, regular backups are essential[1].
Summary
While the iPhone 17 offers advanced water resistance, it is not safe to intentionally submerge it in saltwater or chlorinated pools. Saltwater’s corrosive nature and pool chemicals can degrade seals and internal components, causing irreversible damage. To protect your device, avoid prolonged or deep exposure, use protective cases, and act quickly if accidental contact occurs. Remember, water resistance diminishes over time, and Apple’s warranty excludes water damage coverage, making caution paramount.
In conclusion, treat your iPhone 17 as water-resistant but not waterproof against harsh aquatic environments like saltwater or chlorinated pools to ensure its longevity and performance.
