iPhone Water Resistance Explained: A Series-by-Series Guide and What to Watch Out for When Buying Used
"I want to watch videos in the bath," "I want to use it without worrying about rain," etc. Waterproofing is very important when choosing a smartphone. In particular, since iPhones have different waterproof ratings depending on the model, many people may be anxious, wondering, "Which model can I use in the bath?" or "Does a used phone still have waterproofing?" This article clearly explains the waterproofing mechanism of iPhones and the compatibility status by series. Furthermore, it introduces how to choose a used iPhone to avoid compromising its waterproofing, and PRODIG's strengths that allow you to purchase with peace of mind.
How waterproof are iPhones?

iPhone waterproofing is not "completely waterproof"; it is accurately called "water-resistant." By understanding the difference and standards, you can use it correctly and safely.
Difference between waterproof and water-resistant
"Waterproof" refers to a function that completely blocks water, such as a waterproof camera for diving. On the other hand, "water-resistant" means the ability to prevent temporary water intrusion, and smartphones are merely "water-resistant." In other words, it is a safeguard in case of accidental drops into water and is not suitable for prolonged submersion, such as in a bath.
IP standards and iPhone waterproof ratings
iPhone's waterproofing performance is expressed by the international standard "IP Code." You may have seen notations like IP67 or IP68. IP6X indicates the "degree of protection against dust," and IPX7 or IPX8 indicates the "degree of protection against water." For example, iPhone 7 to iPhone X are IP67-rated (can withstand water immersion up to 1 meter for up to 30 minutes), and most iPhones from iPhone 11 onwards support IP68 (even higher waterproofing performance).
iPhone Waterproofing by Series

The waterproofing performance of iPhones varies depending on the model's IP standard. The table below summarizes the waterproof ratings and water resistance guidelines for major models. Please use it as a reference when choosing a model with waterproofing in mind.
| Model | Waterproof Rating | Water Resistance (Apple Official Test Conditions) | Usage Examples (Guideline) |
|---|---|---|---|
| iPhone 8 | IP67 | Water resistant up to 1m for up to 30 minutes | OK for rain, around the kitchen, splashes from handwashing. Not for baths or the sea. |
| iPhone X | IP67 | Water resistant up to 1m for up to 30 minutes | Same as iPhone 8, splash-resistant level. Avoid baths and seawater. |
| iPhone 11 | IP68 | Water resistant up to 2m for up to 30 minutes | OK for rain, splashes by the poolside. Not for baths or the sea. |
| iPhone SE2 (2020) | IP67 | Water resistant up to 1m for up to 30 minutes | Equivalent to iPhone 8. Safe in rain or kitchen, but not for long baths. |
| iPhone 12 | IP68 | Water resistant up to 6m for up to 30 minutes | Strong against splashes + short-term submersion, but not for bath steam or seawater. |
| iPhone 13 | IP68 | Water resistant up to 6m for up to 30 minutes | Same as iPhone 12. Fine for showers, but baths/sea are not recommended. |
| iPhone SE3 (2022) | IP67 | Water resistant up to 1m for up to 30 minutes | Splash-resistant level. Avoid prolonged use in the bath or submersion. |
| iPhone 14 | IP68 | Water resistant up to 6m for up to 30 minutes | Strong water resistance, but bath steam or warm water are not intended. Seawater is also not recommended. |
| iPhone 15 | IP68 | Water resistant up to 6m for up to 30 minutes | Same as iPhone 14. Rain, short-term submersion are OK. Baths are not recommended. |
| iPhone 16 | IP68 | Water resistant up to 6m for up to 30 minutes (estimated) | Expected to have the same water resistance level as iPhone 15. Safe for daily life. |
Water-resistant models from iPhone 7 onwards
Apple's first water-resistant iPhones were the iPhone 7/7 Plus. From these models, the IP67 standard was equipped as standard, allowing them to be used without issue in rain or with kitchen splashes. Subsequent models, including the iPhone 8, iPhone X, and iPhone XR, also comply with IP67.
Waterproofing level of the latest models
iPhone 11 Pro series and later models have obtained an IP68 rating and are said to be able to withstand submersion up to 4 meters for 30 minutes. However, this is under laboratory test conditions for new devices, and performance may degrade due to aging or frame distortion caused by drops.
How to check the waterproofing of used iPhones
When purchasing a used iPhone, it is important to understand that its "waterproofing performance is not guaranteed." Even Apple officially states that waterproofing is not covered by the warranty. When choosing a used device, check for scratches or deformities around the frame, speaker holes, and SIM tray, and select a "verified working" device from a reputable vendor.
Precautions when choosing a used waterproof iPhone

When choosing a used iPhone, it's important to select it with key points in mind, assuming that its waterproofing performance may have degraded.
Causes of reduced waterproofing performance
Waterproofing performance is secured by adhesives and seals in the casing. If the frame is distorted by a drop or impact, water can easily enter through small gaps. Also, devices with a history of repairs should be viewed with caution, as waterproofing is often not restored when repaired by unauthorized shops.
Points to check before purchase
"Red ROM warranty," "operation verified," and "no damage to frame or ports" are the minimum requirements for a trustworthy used store. If you plan to use it for waterproofing, aim for a battery capacity of 80% or more. Furthermore, it is recommended to reduce risk by using a waterproof case after purchase.

If you want to buy a used iPhone with waterproofing with peace of mind, where you buy it is the most important factor. PRODIG offers services that meet these needs.
