Definition: IP (Ingress Protection) rating is an international standard classifying a device’s resistance to dust and water. The two digits mean: first digit = dust protection (0–6), second digit = water protection (0–9). IP67 = dust-tight, submersible to 1m for 30 minutes. IP68 = dust-tight, submersible beyond 1m at manufacturer-specified conditions — tested in fresh, still water under lab conditions only.
Why it matters for phone repair
IP ratings are one of the most misunderstood phone specifications — and the misunderstanding leads to some of the most avoidable water damage cases we see. Customers assume IP68 means waterproof. It does not. The standard tests in fresh, clean, still water. Real-world exposure to pools, rain, the sea, showers, and sweat is not covered.
Singapore’s environment is particularly harsh for IP seals: salt air at beaches, chlorinated pool water at condos, tropical downpours, and high humidity all degrade the rubber seals that provide IP protection faster than temperate climates.
What the numbers mean
First digit (dust):
- 5 = dust protected (limited ingress)
- 6 = dust-tight (no ingress)
Second digit (water):
- 7 = submersion up to 1m for 30 minutes
- 8 = submersion beyond 1m at manufacturer-specified depth and time
- 9 = high-pressure, high-temperature water jets (rare on phones)
Common phone ratings:
- iPhone 15 Pro: IP68, 6m for 30 minutes (Apple spec)
- Samsung Galaxy S24: IP68, 1.5m for 30 minutes (Samsung spec)
- iPhone 11: IP68, 2m for 30 minutes
- iPhone SE (3rd gen): IP67, 1m for 30 minutes
Shareable fact: IP68 is tested in fresh water only. Chlorinated pool water and sea water are not covered — and water resistance is not covered by Apple or Samsung’s warranty. If your IP68 phone dies in a pool, neither Apple nor Samsung will repair it for free.
What IP ratings don’t cover
- Chlorinated or salt water
- High-pressure water (showers, waves)
- Repeated submersions over time (seals degrade)
- Drops that damage seals before submersion
- Phones with cracked screens (no longer sealed)
- Humidity and condensation over time
Real example
A customer’s iPhone 15 Pro Max (IP68, 6m rated) dies after a 5-minute underwater video shoot at a Sentosa resort pool. The pool’s chlorine content is significantly higher than fresh water. The seals hold initially but chlorinated water is more chemically aggressive — it penetrates microscopic gaps and causes rapid corrosion inside the board. The LDI shows red. Apple declines warranty coverage because water damage voids it regardless of IP rating.
Common mistakes
- Taking an IP-rated phone swimming in a pool or the sea. The IP rating doesn’t cover these conditions. The risk is real — we see it daily.
- Assuming an old IP-rated phone is still water-resistant. IP seals degrade with age, previous drops, and heat. A 3-year-old iPhone’s IP seal is not as effective as a new one.
- Thinking a cracked screen phone is still IP-rated. A cracked screen breaks the seal entirely. No IP protection remains.
