What to Do When Your Phone Gets Water Damage

Published 2026-10-16 · Marion Phone Repair

You drop your phone in water — a toilet, a pool, a sink, a puddle — and the panic sets in. The internet says put it in rice. Your friend says use a hair dryer. Neither of these actually works, and one can make the damage worse. Water damage is a race against corrosion, and what you do in the first 30 minutes matters more than anything else.

What to do immediately

The moment your phone comes out of the water, follow these steps in order:

Get it out of the water and turn it off. If the phone is still on, power it down immediately. Do not try to check if it still works by unlocking it, opening apps, or making a call. Electricity flowing through wet circuits is what causes the real damage — short circuits that burn out components. If the phone already turned itself off, do not try to turn it back on
Remove what you can. Take off the case. Remove the SIM card and SIM tray (use the SIM ejection tool or a paperclip). If your phone has a removable battery (rare on modern phones), remove it. Every opening you create helps water escape
Shake out excess water. Hold the phone with the charging port facing down and gently shake or tap it against your palm. Water collects in the charging port, speaker grills, and SIM tray slot. Getting the bulk water out quickly is important
Wipe the outside. Use a lint-free cloth or paper towel to dry every surface. Pay attention to the charging port, headphone jack (if present), speaker openings, and the SIM tray opening
Do not plug it in or charge it. Charging a wet phone can short the charging circuit, the battery management chip, or worse. Do not plug in a cable for at least 24 to 48 hours, even if the phone appears dry on the outside

Why rice does not work

Putting a phone in a bag of rice is the most repeated piece of tech advice on the internet, and it is essentially useless. Here is why:

Rice does not absorb moisture from inside a sealed phone. Modern phones are designed to keep things out, which also means they keep water in. Rice sitting against the outside of a phone cannot pull water out of the sealed interior through the tiny gaps around buttons and ports
Rice introduces starch dust and debris. Small rice particles and starch dust get pushed into the charging port, speaker grills, and SIM tray slot by the same openings water entered through. This creates additional problems when the phone is taken to a repair shop — the technician now has to clean rice debris out before they can even assess the water damage
Testing has shown rice performs no better than open air. Multiple controlled tests (including by repair industry groups and consumer tech outlets) have demonstrated that a phone left in open air dries at the same rate or faster than a phone buried in rice. The rice gives a false sense of action without actually helping

What actually helps with drying

The goal is to get air moving around and through the phone to evaporate trapped water before corrosion starts:

Silica gel packets. If you have them (from shoe boxes, electronics packaging, or bought in bulk), silica gel is a genuine desiccant that absorbs moisture from the air around it. Place the phone and a handful of silica gel packets in a sealed container or zip-lock bag for 24 to 48 hours. This is measurably more effective than rice
A fan or gentle airflow. Place the phone in front of a fan or in a well-ventilated area with the charging port facing down. Moving air accelerates evaporation through the openings. Do not use heat (see below)
Time. Even with no special materials, leaving the phone powered off in a dry room for 48 hours lets much of the moisture evaporate naturally. Patience is the hardest part but also the most effective

What makes water damage worse

Several common reactions to a wet phone actively increase the damage:

Turning the phone on to check if it works. This is the most damaging thing you can do. If water is still inside the phone and you power it on, electrical current flows through wet pathways it was never designed to travel. This causes short circuits that can destroy the logic board, burn traces on the circuit board, and kill components that would have survived if the phone had stayed off
Using a hair dryer or heat gun. Heat can warp internal components, melt adhesives that hold the screen and battery in place, and push moisture deeper into the phone rather than drawing it out. The temperatures that effectively evaporate water are also high enough to damage plastic connectors, display cables, and battery cells
Putting it in the oven or microwave. This destroys the phone entirely. Microwaves will arc against the metal components and can cause the battery to catch fire. Ovens, even at low temperatures, exceed the safe operating range for lithium batteries and LCD or OLED screens
Shaking the phone vigorously. Gentle tapping to remove pooled water is fine. Violent shaking can spread water to parts of the phone it had not reached yet, particularly into the display assembly or under the battery
Charging it before it is fully dry. The charging port has exposed electrical contacts. If water or moisture is still present when you plug in a cable, the charger sends current through those wet contacts. This corrodes the port pins, can damage the charging IC, and in some cases causes visible burn marks on the port

Water resistance ratings are not waterproof

Modern phones carry IP ratings — IP67, IP68 — that indicate water resistance, not waterproofness. Understanding what these ratings mean helps set expectations:

IP67 (many mid-range phones): rated for submersion in up to 1 meter of fresh water for up to 30 minutes under controlled lab conditions
IP68 (most flagship phones): rated for submersion in up to 1.5 meters for 30 minutes. Some manufacturers rate deeper or longer, but the conditions are still controlled
What the rating does not cover: pool water (chlorine degrades seals), ocean water (salt accelerates corrosion dramatically), hot water (steam and heat weaken gaskets), soapy water (surfactants break surface tension and push past seals), and drops into water from height (impact force pushes water past seals designed for gentle submersion)
Water resistance degrades over time. The adhesive seals around the screen, ports, and buttons weaken with age, heat exposure, drops, and normal use. A two-year-old phone with an IP68 rating is significantly less water-resistant than it was on day one

Signs of water damage

After the drying period, power the phone on and check for these symptoms:

Screen discoloration or spots. Water under the display creates visible patches, usually along edges or corners. These may dry out over time, but large or dark spots usually indicate the display needs replacement
Speaker distortion. Muffled, crackly, or no sound from earpiece or loudspeaker. Water in the speaker enclosure changes the sound characteristics. Minor moisture may clear up; persistent distortion means the speaker or its contacts are corroded
Camera fog. Moisture inside the camera lens assembly creates a foggy or hazy appearance in photos. This sometimes clears on its own over several days but often requires disassembly to fully resolve
Erratic touchscreen. Ghost touches, unresponsive areas, or the screen registering touches you did not make. Water on the digitizer layer causes false inputs
Charging issues. The phone does not charge, charges intermittently, or shows a moisture-detected warning. Corrosion on the charging port contacts is one of the earliest and most common consequences of water exposure
Battery draining abnormally fast. Corrosion on battery contacts or damage to the power management circuit causes the battery to discharge faster than normal

Professional water damage repair

Marion Phone Repair handles water damage assessment and repair on iPhones, Samsung Galaxy, Google Pixel, and other phones. We open the device, inspect for corrosion, ultrasonically clean the logic board and connectors, replace damaged components, and test every function before returning the phone. The sooner a water-damaged phone reaches a repair bench, the better the chances of full recovery.
