Short answer: no. Is the iPhone 18 Pro Max waterproof? It isn't, and neither is the Pro. Both are water resistant, not waterproof, and the difference matters. Their shared IP68 rating is solid protection against rain, splashes, and a dropped drink. It's not a promise that the phone can be used underwater.
What Does IP68 Mean on the iPhone 18?
IP68 is a rating from the IEC 60529 standard, and each digit measures something different. The first digit covers dust, and a 6 means fully dust-tight. The second covers water, and an 8 means the device survived continuous submersion beyond 1 meter in a lab test. For the iPhone 18 Pro, Apple specifies 6 meters for up to 30 minutes.
Apple applies the same rating to both Pro models, so the bigger phone isn't any more or less water resistant. Apple is clear that this is a lab result. Its footnote says splash, water, and dust resistance are not permanent conditions, and that resistance might decrease as a result of normal wear. Liquid damage also isn't covered under warranty, so the rating is a design spec, not a repair guarantee (Apple Support).
What Can Weaken Water Resistance Over Time?
Everyday wear can, according to Apple, and damage can too. A cracked screen or back glass, or a phone that's been dropped, can compromise the seal even if it still looks fine. That's the main reason drop protection matters for a water-resistant phone: the rating describes a phone in its original condition, not one that's taken a few hits.
Does an iPhone 18 Phone Case Make It Waterproof?
No. A good iPhone 18 phone case doesn't change the phone's IP rating, and a standard case can't restore resistance that's already been lost. Scorpify's cases aren't designed for submersion, so if you need to take a phone underwater on purpose, that's a job for a dedicated waterproof case, not an everyday one.
What a well-fitted case does is protect the phone from the damage that leads to trouble in the first place. The best iPhone 18 Pro Max case for everyday moisture isn't a waterproof one, it's one that fits the phone exactly and protects it from drops. The same goes for the best iPhone 18 Pro case. Every case in our iPhone 18 cases lineup is built for a specific model, with RippleTech multi-layer shock protection, a 10FT drop rating (MIL-STD-810G), and N52 magnets for MagSafe.
If you already know which phone you have, go straight to the iPhone 18 Pro Max cases or the iPhone 18 Pro cases. Our iPhone case compatibility guide explains why it needs to be the exact model.
Which Liquids Are Harder on an iPhone Than Water?
Apple's water-resistance guidance covers more than plain water. It says to avoid swimming or bathing with your iPhone, and to minimize exposure to soap, detergent, acids or acidic foods, and to liquids like perfume and lotions (Apple Support). The rating comes from lab tests in water, so a splash of something else isn't covered by the same assumptions. That's why a spilled latte or a spritz of perfume is worth dealing with right away, even on a phone rated IP68, because the rating doesn't make it immune to everything.
If one of those liquids does land on the phone, Apple's advice is to rinse the affected area with tap water, then wipe the phone with a soft, lint-free cloth. After that, follow the drying steps below.
What Should You Do If Your iPhone 18 Gets Wet?
Unplug anything connected, and don't charge it. Apple advises against charging a wet iPhone, and warns that charging while wet can corrode the connector pins (Apple Support). Then work through this order:
- Take the case off. This keeps moisture from sitting between the case and the phone. Wipe the outside with a soft, lint-free cloth.
- Shake out the connector. Tap the phone gently against your hand with the connector facing down.
- Let it air-dry. Leave it in a dry area with some airflow. Apple says it can take up to 24 hours to dry fully.
- Check the speaker. If sound is muffled, lay the phone speaker-side down on a lint-free cloth. Apple notes that water can degrade speaker or microphone performance until it evaporates (Apple Support).
- Plug in only when it's completely dry.
Skip the shortcuts. Apple says not to use a heat source or compressed air, and not to push a cotton swab or paper towel into the connector. It also warns against putting the phone in rice, because rice particles could damage it.

FAQ
Can I swim with an iPhone 18 Pro Max? It's not what the rating is for. IP68 describes a lab test, and Apple notes that liquid damage isn't covered under warranty. Treat the phone as splash resistant, not as underwater gear.
Is the iPhone 18 Pro Max more water resistant than the iPhone 18 Pro? No. Apple gives both the same IP68 rating, tested under the same lab conditions.
Does a phone case make the iPhone 18 waterproof? No. A case doesn't change the phone's rating. It helps by protecting the phone from drops and everyday knocks.
Is rice a good way to dry a wet iPhone? No. Apple specifically warns against it, because rice particles could damage the phone. Air-dry it in a spot with some airflow instead.
How long should I wait before charging a wet iPhone 18? Until the phone and the cable are completely dry. Apple says full drying can take up to 24 hours, so don't plug in just because the screen looks dry.
Is the standard iPhone 18 water resistant? It hasn't launched yet, so there's no confirmed rating. Current reporting points to a spring 2027 release.
