The arrival of the iPhone 15 Pro Max heralded a new era of mobile technology, featuring an aerospace-grade titanium design and a spectacular Super Retina XDR display. As Apple’s flagship device, its engineering is undeniably robust, built to handle the rigours of modern life, including an official IP68 rating for ingress protection. This certification technically allows the device to withstand submersion in water up to 6 meters for 30 minutes under controlled laboratory conditions. It is a marvel of precision manufacturing, incorporating advanced seals designed to repel dust and moisture.
However, a crucial distinction must always be made: water resistance is not the same as water proofing. The seals protecting your Pro Max are subject to natural wear and tear, and a hard drop or even a minor crack can compromise the integrity of the resistance. Exposure to liquids other than fresh water—such as saltwater, chlorinated pool water, or sugary drinks—introduces corrosive elements that can rapidly bypass the device’s protections, turning a momentary splash into a critical hardware failure. This is why a water-damaged iPhone 15 Pro Max quickly turns from a premium device into a serious repair challenge.
🚨 The moment liquid meets your iPhone 15 Pro Max, a race against corrosion begins, demanding immediate and correct action to prevent permanent damage.

Immediate Action: 7 Critical Steps to Take When Your iPhone 15 Pro Max Gets Wet
In the event your iPhone 15 Pro Max suffers a liquid ingress incident, your actions in the first hour are paramount to the device’s survival. Following these crucial steps can greatly increase the chances of a successful professional recovery:
- Power Down Immediately: The single most important step is to turn the phone off at once. If the liquid causes a short circuit while the phone is operating, it can lead to irreversible logic board damage. Do not attempt to test the screen or any functions.
- Disconnect All Accessories: Unplug the charging cable, headphones, or any other peripheral connected to the USB-C port. Never attempt to charge the device while it is wet, as this introduces power to a liquid-contaminated circuit, almost certainly causing a short circuit.
- Remove the Case and SIM Tray: Any case will trap moisture against the phone’s surface, and the SIM card tray opening is a direct, open conduit to the phone's internals. Remove both immediately to allow air flow and access.
- Wipe Down the Exterior: Use a soft, absorbent, and lint-free cloth—such as a microfiber cloth—to gently wipe down all external surfaces. If the phone was exposed to something corrosive like beer or saltwater, Apple advises rinsing it briefly with fresh tap water before drying.
- Tap Out Excess Liquid: Hold the iPhone with the USB-C port facing downward. Gently tap the phone against your hand. This helps to expel any liquid trapped inside the charging port and speakers.
- Allow Air Drying: Place the iPhone in a dry area with sufficient airflow for at least 48 to 72 hours. You can place it in front of a fan to help cool air blow into the port. Do NOT use a hairdryer, oven, or any external heat source, and absolutely do not use rice. Rice does nothing but potentially introduce starch, debris, and corrosion-accelerating humidity.
- Seek Professional Assessment: Even if the phone turns back on after drying, internal corrosion may be silently progressing. Components on the delicate "sandwich board" structure of the iPhone 15 Pro Max can trap liquid, leading to unpredictable failure days or weeks later. A professional assessment is mandatory to clean and treat any internal contamination.
DIY Disclaimer: While the steps above are crucial for immediate damage mitigation, they are not a repair. Water damage often necessitates a complex, component-level repair and deep internal cleaning. Attempting to disassemble the device yourself will void any remaining warranty and can easily lead to catastrophic permanent failure.
Beyond the Basics: Why Professional Board-Level Repair is Essential
The repair of a water-damaged iPhone 15 Pro Max transcends simple part swapping; it requires micro-soldering and deep diagnostic expertise. The logic board is the beating heart of your phone, and liquid damage often causes corrosion that eats away at tiny components and traces. When this happens, only a professional technician equipped with specialised tools can effectively clean and restore power to the board.
