Water is one of the biggest threats to modern smartphones. Even though many devices are labeled as “water-resistant,” they’re not completely waterproof. A few drops can slip through the speaker holes, charging port, or SIM tray — leading to short circuits, screen issues, or battery failure.

If your phone recently got wet, don’t panic. Here’s what you can do to fix it safely before the damage spreads.

🚨 Step 1: Act Immediately

When your phone comes in contact with water:

  1. Turn it off immediately.
    Keeping it on can cause short circuits on the motherboard.

  2. Do not plug it in to charge.
    This can fry delicate circuits instantly.

  3. Remove the SIM, SD card, and case.
    Let air circulate through the slots.

  4. Dry it gently.
    Use a soft cloth — avoid hair dryers or direct sunlight.

If your phone refuses to turn back on afterward, see our step-by-step guide on fixing a phone that won’t turn on for safe recovery steps.

💧 Step 2: Open and Inspect Carefully

If you have a basic repair toolkit, carefully remove the back cover and disconnect the battery. You can follow the same approach outlined in our DIY Mobile Repair Kit guide to learn how to use the right tools safely.

Look out for:

  • White corrosion marks (on battery or board connectors)

  • Moisture near the charging port

  • Discolored or foggy camera lenses

Gently clean the affected areas using isopropyl alcohol (IPA 99%) and a soft brush. This helps remove water residue and prevent corrosion.

⚡ Step 3: Dry Properly

Place the phone in a dry, warm area for at least 24–48 hours.
Avoid using rice — it’s a myth. Instead, use silica gel packets or a small airtight container to absorb moisture.

For slightly wet devices, a desk fan or dehumidifier works better than heat. Excessive heat can warp internal components or damage your screen’s adhesive.

🧠 Step 4: Check for Hidden Issues

Once dry, test for:

  • Sound or speaker distortion

  • Charging port errors

  • Camera fog or blurred photos

  • Screen flickering

If your phone still charges slowly or shows a “moisture detected” error, follow our guide on fixing slow charging phones — it covers cleaning and port repair steps that also apply to water damage.

🧩 Step 5: When to Seek Professional Help

If your phone shows no sign of life even after cleaning and drying, it may need board-level repair. At that point, it’s best to visit a certified technician who can test the power IC and charging circuit using a multimeter.

🧯 Bonus: How to Prevent Future Water Damage

  • Always use a waterproof phone pouch near beaches or pools.

  • Avoid answering calls in the rain.

  • Don’t charge your phone immediately after exposure to humidity.

  • Keep your charging port clean and dry — moisture often lingers there.
