The next sixty minutes determine whether your phone survives intact or whether you're facing a logic board replacement. This guide walks you through exactly what to do, and what to avoid, based on what we've learned from repairing iPhones across Johannesburg for the past decade.
What Happens Inside When Water Enters Your iPhone
Modern iPhones have impressive IP ratings. The iPhone 14 and 15 series are rated IP68, meaning they'll survive up to 6 metres of water for 30 minutes. But "survive" doesn't mean "escape unharmed." Water itself isn't the enemy, corrosion is.
Once water reaches internal circuits, it creates conductive pathways between components. Your phone's logic board operates at tiny voltages. A film of moisture can short connections, kill processors, and corrode the microscopic traces that carry electrical signals. Within hours, oxidation begins. Within days, the damage becomes irreversible.
This is why that desperate urge to turn your phone on is so dangerous. Applying power to wet circuits accelerates corrosion dramatically. We've seen phones that would have recovered with proper drying fail completely because someone switched them on too soon.
Immediate Action: The First Hour
Step 1: Stop using it immediately. Power off your iPhone right now. Don't swipe, don't check messages, don't wait to "see if it's okay." If the phone is already off, leave it off.
Step 2: Remove the SIM card. Open the SIM tray using the ejector tool (or a straightened paperclip). This small action prevents corrosion in the SIM slot and gives moisture an exit point.
Step 3: Dry the exterior. Use a lint-free cloth, microfibre cloths work perfectly, and gently pat the outside. Don't rub aggressively. Pay special attention to the charging port, speaker grilles, and microphone openings. These are where water pools.
Step 4: Never use heat. This is critical. Don't use a hair dryer, don't place the phone near a heater, and don't put it in an oven (yes, people do this). Heat accelerates chemical reactions that corrode your logic board. It also risks damaging the display or battery.
Step 5: Get to silica gel or uncooked rice, if you act immediately. The old rice trick actually works, but only if you do it within the first 30 minutes. Place your iPhone in a container filled with uncooked rice or silica gel packets. Don't use cooked rice. This will absorb surface moisture, but it won't stop internal corrosion entirely.
The Critical Next 24 to 48 Hours
After the first hour, your priority shifts from rapid drying to preventing corrosion. Here's where most people go wrong.
Rice and silica gel help, but they're not sufficient for water that's already entered the logic board. At this stage, you need professional intervention. Water trapped inside your device will begin oxidising components, and no amount of ambient air-drying will reverse that process.
We recommend bringing your iPhone in for professional assessment within 12 hours of water exposure. At ZA Support's Hyde Park workshop, we perform a detailed inspection using specialist equipment to identify exactly where water has penetrated and what components are at risk.
Our assessment costs from R599 and takes approximately 30 minutes. During this time, we'll photograph the logic board under magnification, test component voltages, and determine whether your phone can recover with a professional dry-out treatment or whether it requires liquid damage repair.
If corrosion hasn't started, professional ultrasonic cleaning combined with controlled drying can save your device completely. If it has started, early intervention is the difference between a R1,200 repair and a R4,500 logic board replacement.
What Not to Do
Never attempt to disassemble your iPhone yourself. The display is glued to the frame with adhesive that requires heating to remove safely, without proper tools and environment control, you'll crack the screen and compound your costs.
Never use compressed air. This forces water deeper into the device rather than removing it.
Never charge your phone or connect it to a computer. This applies even if it seems to be working. Applying power accelerates corrosion.
Never wait more than 48 hours before seeking help. After this point, corrosion becomes aggressive, and your phone's recovery chances drop significantly.
Professional Water Damage Repair at ZA Support
If your iPhone has suffered water damage, we've successfully restored more than 14,000 devices across Johannesburg, many of them after being submerged for minutes or even hours.
Our process begins with a full diagnostic assessment. We use thermal imaging to identify moisture hot spots and micro-ohm testing to detect short circuits invisible to the naked eye. Based on these results, we either recommend professional dry-out (typically R1,800-R2,400) or targeted logic board repair if corrosion has already begun.
Every repair includes our industry-leading 3-year warranty. If your phone fails within that period due to water damage we've treated, we'll repair it free. That confidence comes from doing this repair hundreds of times per year.
Timing matters. Johannesburg's load shedding and humidity mean water damage can worsen quickly. We prioritise water damage assessments and can often turn repairs around within 24 to 48 hours.
Contact us online or WhatsApp us on 064 529 5863 to book your diagnostic assessment today. If you prefer to visit us in Hyde Park, book online at zasupport.com/book for a guaranteed appointment slot.

Frequently Asked Questions
Q: Will my iPhone definitely die if it gets wet?
Modern iPhones are water-resistant, not waterproof. The IP68 rating means your phone can survive accidental splashing and brief submersion. The real risk comes from how you respond in the first hour. Power it off immediately, avoid heat, and don't charge it. Most water-exposed iPhones recover fully if you seek professional assessment within 12 hours.
Q: Can I use a hair dryer to dry my iPhone?
No. Heat accelerates the chemical reactions that corrode your logic board. It also risks damaging the display adhesive and battery. The best approach is cool air circulation in a dry environment, or professional ultrasonic cleaning, which removes water from internal spaces without heat damage.
Q: How long can an iPhone survive underwater?
iPhone 14 and later models are rated IP68, surviving up to 6 metres of fresh water for 30 minutes. Salt water, chlorinated water, and tap water with minerals all accelerate corrosion. Even if your phone survives 30 minutes, bring it to us immediately, internal water damage develops over hours, not days.
Q: Is rice really effective for water damage?
Rice works for surface moisture if you act within the first 30 minutes, but it won't remove water from deep inside your logic board. It's a helpful first step only. Professional drying using ultrasonic equipment and controlled humidity is far more effective and should follow within 12 hours.
Q: What's the difference between a water-damaged phone you can fix and one that's beyond repair?
If corrosion hasn't reached critical components, professional cleaning and dry-out restores your phone completely. If corrosion has damaged the logic board's trace pathways or killed essential chips, we'll need to repair or replace those components, this costs more but is usually still possible. We assess this in our R599 diagnostic appointment.
Q: Do I need to replace my battery after water damage?
Not always. If your phone was powered off immediately and dried properly, the battery is rarely affected. However, we always test battery health as part of water damage assessment. If the battery was exposed to sustained moisture or shows degradation, we'll replace it as part of your repair, typically included in our service at no extra cost.
