Your iPhone 16 has an IP68 rating, but that does not mean it is waterproof. Here is what the rating actually means, where it falls short in real life, and exactly what to do when water still gets inside.
Every iPhone 16 model -- the standard iPhone 16, iPhone 16 Plus, iPhone 16 Pro, and iPhone 16 Pro Max -- carries an IP68 rating under IEC standard 60529. But most people misunderstand what those two digits represent.
The "IP" stands for Ingress Protection, an international standard that rates how well a device resists intrusion by solids and liquids. The first digit (6) rates solid particle protection on a scale of 0-6. The second digit (8) rates liquid protection on a scale of 0-9K.
A rating of 6 is the highest possible score for solid particle protection. It means the device is completely dust-tight -- no dust particles can enter the enclosure under any conditions. Your iPhone 16 achieves this maximum rating.
An 8 rating means the device can withstand continuous submersion in water beyond 1 meter. For the iPhone 16 and iPhone 16 Plus, Apple specifies up to 6 meters for 30 minutes. The iPhone 16 Pro and Pro Max are rated for the same depth and duration.
IP68 testing is performed in a controlled laboratory using fresh, still water at room temperature. Real-world conditions -- pool chemicals, ocean salt, pressure from jumping into water, hot tub heat -- are never part of the test.
IP68 resistance degrades over time. Every drop, every case removal, every temperature change weakens the adhesive seals that keep water out. A two-year-old iPhone 16 does not have the same water resistance as a new one.
The IP68 rating is tested under ideal laboratory conditions that rarely match how you actually use your phone. Here are the scenarios where your iPhone 16's water resistance falls short.
Chlorine is a chemical solvent that degrades the adhesive gaskets sealing your iPhone. Repeated pool exposure accelerates seal failure. IP68 testing does not involve chlorinated water.
Salt water is highly corrosive to electronics. Salt crystals can lodge in speaker grilles and ports, continuing to draw moisture and cause corrosion long after you leave the beach.
Heat causes metal components to expand at different rates than gaskets, creating microscopic gaps. Steam can penetrate seals that would block liquid water. Never bring your iPhone into a hot tub or sauna.
IP68 tests use still water. The pressure from diving deeper than rated, jumping into a pool, or being hit by a water jet (like a shower head at close range) exceeds the seal specifications.
Soap reduces water's surface tension, allowing it to penetrate gaps that pure water cannot. Washing your phone under a faucet with soap is riskier than a brief freshwater splash.
Even a minor drop can compromise the internal seals without visible damage. A cracked screen or dented frame creates pathways for water that bypass IP68 protection entirely.

| iPhone 15 Pro / Pro Max | IP68 | 6 meters | 30 minutes |
| iPhone 14 / 14 Pro | IP68 | 6 meters | 30 minutes |
| iPhone 13 / 13 Pro | IP68 | 6 meters | 30 minutes |
| iPhone 12 / 12 Pro | IP68 | 6 meters | 30 minutes |
| iPhone 11 Pro / Pro Max | IP68 | 4 meters | 30 minutes |
| iPhone 11 | IP68 | 2 meters | 30 minutes |
| iPhone 7 / 8 | IP67 | 1 meter | 30 minutes |
This is where most people get the unpleasant surprise. Despite marketing the iPhone 16 with its IP68 rating, Apple's warranty and AppleCare+ have specific exclusions for water damage.
Apple's one-year limited warranty explicitly excludes damage caused by liquid. Every iPhone has liquid contact indicators (LCIs) -- small strips inside the SIM tray slot and charging port that turn red when exposed to liquid. If a technician sees a triggered LCI, the repair is not covered under standard warranty. You will pay out-of-pocket prices, which can range from $199 to $599 depending on the model and extent of damage.
AppleCare+ does cover accidental damage, including liquid damage, but with a deductible. For iPhone 16, the accidental damage service fee is $99 for screen damage or $149 for other damage (which includes water damage). You are limited to two incidents per year. AppleCare+ costs $179-$269 depending on the model, making the total cost of a water damage repair with AppleCare+ between $328 and $418.
LCIs activate upon contact with any liquid -- not just full submersion. High humidity, condensation from temperature changes, even sweat can trigger these indicators in some cases. Once triggered, there is no way to reset them. Apple technicians check LCIs as the first step in any service evaluation, and a triggered indicator changes the repair from warranty-covered to paid service.

Even with IP68 protection, water can and does get into iPhone 16 speakers, ports, and occasionally past the seals. Here is the step-by-step protocol when it happens.
IP68 is your safety net, not your license to swim with your phone. These practical steps significantly reduce your risk of water damage.
For pools, beaches, and boats, a certified waterproof pouch (IPX8-rated) provides a physical barrier that does not degrade over time like adhesive seals. Most allow full touchscreen use and photo taking. Cost: $10-25.
Never bring your iPhone into a shower, hot tub, or sauna. Heat compromises seals, and steam penetrates gaps that liquid water cannot. If you want music in the shower, use a waterproof Bluetooth speaker instead.
Any drop can compromise water resistance. After a significant drop, inspect the edges for gaps between the screen and frame. Even if the phone looks fine, the internal seals may be damaged. Consider a professional inspection if the phone was dropped into water shortly after a fall.
Download Eject Water before you need it. When water gets into your speakers, you want the solution immediately available -- not scrambling to download an app with muffled audio and a wet screen.
When water gets past your iPhone 16's seals and into the speakers, Eject Water removes it in seconds using the same sound frequency technology as Apple Watch Water Lock.
Download on App Store -- FreeNo. The iPhone 16 is water-resistant, not waterproof. It carries an IP68 rating, which means it can withstand submersion in up to 6 meters of fresh, still water for up to 30 minutes under laboratory conditions. However, this does not make it impervious to water. Chlorine, salt water, soap, steam, and water pressure from activities like diving or water jets can all compromise the seals. Apple explicitly states that water resistance is not a permanent condition and can degrade with normal wear.
IP68 is an Ingress Protection rating under the IEC 60529 standard. The "6" means the device is fully dust-tight (the highest rating for solids). The "8" means it can survive continuous submersion in water deeper than 1 meter -- Apple specifies up to 6 meters for 30 minutes for the iPhone 16 lineup. This testing is done with fresh, still, room-temperature water in a lab. Real-world conditions with chemicals, pressure, heat, or wear may reduce this protection.
You should not intentionally submerge your iPhone 16 Pro Max in a pool. While the IP68 rating provides protection against accidental submersion, pool water contains chlorine and other chemicals that degrade the adhesive gaskets over time. Repeated exposure increases the risk significantly. If your phone accidentally falls in the pool, retrieve it immediately, dry it thoroughly, and use Eject Water to clear the speakers. For intentional underwater photography, use a waterproof case or pouch.
No. Apple's standard one-year limited warranty does not cover liquid damage on any iPhone, including the iPhone 16. If the liquid contact indicators (LCIs) inside the phone have been triggered, Apple will classify the issue as liquid damage and charge out-of-warranty prices ($199-$599 depending on the repair). AppleCare+ with accidental damage coverage does cover liquid damage, but with a $149 service fee per incident and a limit of two incidents per year.
In most cases, yes -- a brief drop into a toilet is well within the iPhone 16's IP68 rating (toilet depth is approximately 15-30 cm, far below the 6-meter rating). The main concern is not the water itself but bacteria and contaminants. Retrieve the phone immediately, power it off, clean it thoroughly with a disinfectant wipe (isopropyl alcohol-based), dry all ports, and use Eject Water to clear the speakers. See our complete toilet recovery guide for detailed instructions.
Yes. Apple confirms that "splash, water, and dust resistance are not permanent conditions and resistance might decrease as a result of normal wear." The adhesive seals that provide IP68 protection degrade from drops, temperature cycling, pressure changes, and simple aging. A two-year-old iPhone has measurably less water resistance than a new one. Third-party repairs, screen replacements, and battery swaps can also compromise or eliminate the original water resistance if the seals are not properly reinstated.
Muffled speaker audio is the most common symptom after water exposure, even with IP68 protection. Water gets trapped in the small speaker grille openings and dampens the speaker membrane's vibration. Use the Eject Water app to play a 165Hz tone that physically pushes water out of the speaker -- you will see droplets expelled from the grille. Run 2-3 cycles. This is the same technology Apple uses in Apple Watch Water Lock. For more details, see our How It Works page.
The iPhone 16 and iPhone 15 share the same IP68 rating with identical specifications: up to 6 meters depth for up to 30 minutes. Apple has not increased the official water resistance rating since the iPhone 12 series. While Apple may have made internal improvements to seal quality and design, the certified rating remains the same. The meaningful improvement happened between iPhone 11 (2 meters) and iPhone 12 (6 meters). Both iPhone 15 and 16 users should exercise the same precautions.
