重點摘要

  • Power off your iPhone immediately after water exposure. Electrical current accelerates internal damage
  • Apple recommends at least 5 hours of air drying. Never use rice or a hair dryer
  • If sound is muffled, use 165Hz 聲波 to eject water from 喇叭s

1. The 3 Emergency Steps You Need to Take Right Now

Okay, deep breaths. What you do in the next 30 minutes can make or break your iPhone’s chances of survival. Here’s the game plan, plain and simple.

First-Aid in 3 Steps

1

Power It Down (and Don’t Charge It!)

Water + electricity = a dead iPhone. If it’s on, turn it off immediately. And whatever you do, do not plug in a charging cable.

2

Wipe It Down

Grab a soft, lint-free cloth and dry off the outside. Pay extra attention to the 喇叭 grilles and Lightning/USB-C port. A gentle shake can help, too.

3

Play a Water Eject Sound

A specific 165Hz sound frequency can literally vibrate water out of your 喇叭s, just like the feature on an Apple Watch. The WaterKick app can diagnose and eject water in one tap.

Once you’ve done these three things as quickly as possible, it’s time to figure out the next steps based on *where* your phone took a dive.

3. What NOT to Do: Common Mistakes That Will Wreck Your iPhone

You’re trying to help, but some “common sense” fixes will actually make things way worse. Avoid these at all costs.

Use a 吹風機

The heat can fry the internal components and battery. Even “cool” air can just push water deeper inside or cause condensation.

Bury it in rice

It’s a myth. Tiny rice particles and starch can get into the ports and cause even more problems. Apple 官方ly warns against this.

Charge it right away

This is the fastest way to short-circuit the logic board. Wait at least 24 hours after it’s fully dry before even thinking about plugging it in.

Put it in the microwave

It sounds like a joke, but people try it. Don’t. It will explode or catch fire. Seriously.

Shake it too hard

A gentle shake is fine, but shaking it violently can spread water to sensitive areas like the camera module or Face ID sensors.

Eject Water Now with WaterKick

Our app uses a combination of 聲波 and haptic vibrations to push water out. Start with the free “Diagnostic Mode” to check your 喇叭s.

5. When to Give Up and Call a Pro

If you’ve tried the first-aid steps and things still aren’t right, it’s time to call a repair shop. These symptoms are usually a sign of serious damage you can’t fix yourself.

⚠️
It won’t turn on

If it still won’t power on after 24 hours of drying, the logic board or battery is likely fried.

⚠️
The screen has lines or is black

This means water got inside the display itself. You’ll probably need a screen replacement.

⚠️
It smells weird or gets hot

This could be a damaged battery. Stop using it immediately—it’s a safety hazard.

6. Frequently Asked Questions

Give it at least 24 hours, but 48 is even better. Using a water eject app can speed this up big time. The goal is to keep running the sound until the WaterKick diagnostic tool gives you the all-clear.

Nope, it’s water-resistant. That resistance (the IP68 等級) wears down over time, especially if you’ve dropped the phone. Apple’s own fine print says water resistance isn’t a permanent condition.

If it turns on, your first priority should be running an iCloud backup. If it’s dead, you’ll need a data recovery service at a repair shop. We cover this in our guide to recovering data from a water-damaged iPhone.

Oh man, I’ve been there twice! Ziploc bags aren’t truly 防水. The seal can easily fail under pressure, especially in a pool or the ocean. You need a proper 防水 case for that.
