How Do I Dry Out a Cell Phone Dropped in a Flood?
Last updated October 25, 2026
The short answer
Immediate First Steps
If your phone gets wet, your first action is critical. Retrieve it from the water and power it down immediately. If the model allows, remove the battery, SIM card, and any case. Do not press any buttons or attempt to turn it on, as this can cause a short circuit. Gently pat the exterior dry with a soft cloth that does not shed lint.
Next, shake the device gently to dislodge water from ports like the charging socket or headphone jack. Use a can of compressed air to blow out moisture from these openings, holding the phone at an angle. Avoid shaking it vigorously, as this can spread water internally. The goal is to stop immediate electrical damage before starting the drying process.
Choosing a Drying Method
The most common drying method involves a desiccant, a substance that absorbs moisture. Uncooked rice is a widely available option, but silica gel packs, often found in new shoe boxes, are more effective. Place your phone and the desiccant into an airtight container like a large zip-top bag or sealed plastic tub. Ensure the phone is completely surrounded.
Leave the phone sealed with the desiccant for a minimum of 48 hours, and up to 72 hours for severe flooding. Store the container in a warm, dry area away from direct sunlight. Resist the urge to check on it frequently, as breaking the seal lets humid air back in. Patience is key for the moisture to be drawn out.
- Never use a hairdryer, oven, or microwave.
- Do not place the phone on a heating vent or radiator.
- Avoid submerging the phone in rubbing alcohol.
- Do not attempt to charge the device while wet.
- Keep the phone away from direct sunlight during drying.
- Do not use paper towels or tissues that can shred.
What to Avoid
Applying heat is a common mistake that can ruin your phone. External heat sources can melt internal adhesives, warp plastic, and permanently damage the screen or battery. They may also drive moisture deeper into the components. A hairdryer can also create static electricity, posing another risk to the delicate circuitry inside the device.
You should also avoid using compressed air to blow directly into the phone at high pressure, as this can force water into deeper areas. Do not attempt to disassemble the phone unless you have specific technical expertise, as you may void warranties or cause irreparable damage. Simple, passive drying is the safest first approach.
After the Drying Period
After at least two full days, carefully remove the phone from the container. Inspect it for any visible moisture in ports or under the screen. Reinsert the battery and SIM card if you removed them. Then, attempt to power the device on. If it does not turn on, try connecting it to its original charger for at least an hour before attempting again.
If the phone powers on, test all functions: the touch screen, speakers, microphone, cameras, and charging port. Check for condensation inside the camera lens, which indicates lingering moisture. Even if it seems to work, corrosion can occur over days or weeks. Monitor the phone for odd behavior, overheating, or rapid battery drain in the following days.
When Professional Help Is Needed
If your phone does not power on after thorough drying, the internal damage may require a specialist. A reputable cell phone repair shop can open the device in a controlled environment, clean corrosion from the logic board with specialized solvents, and replace damaged parts. They have the tools to diagnose issues invisible to the naked eye.
For other valuable items damaged in the same flood, like documents or electronics, specialized drying services exist. Water damage in your home from the same event requires a different professional approach to prevent mold and structural issues. The focus for a home is on rapid water extraction and controlled drying of the building materials.
- Phone won't power on after 72 hours of drying.
- You see visible corrosion on battery contacts.
- The screen displays lines, discoloration, or does not light up.
- The device overheats rapidly when powered.
- Audio functions like the speaker or microphone fail.
- The phone only works when plugged into a charger.

Can I use a vacuum cleaner to suck out the water?
Using a vacuum is not recommended. The suction is rarely strong enough to pull moisture from tiny components, and it can create static electricity that may fry the phone's circuitry. Static discharge is a significant risk when using household appliances not designed for electronics repair.
How long should I wait before trying to charge it?
You should wait until you are completely certain the phone is dry inside, which typically means after the full 48 to 72 hour drying period. Never plug in a charger while the phone is wet or if you suspect internal moisture, as this is the most common cause of permanent short-circuit damage.
What if my phone was in saltwater or flood water?
Saltwater and contaminated flood water are more corrosive than clean water. If possible, rinse the phone gently with distilled water or isopropyl alcohol to displace the salts before the drying process. This step can help reduce corrosion, but the chance of permanent damage is significantly higher with these types of water.
