Water-Damaged Phone: Exactly What to Do in the First Hour (2026)
A phone in water is a race against corrosion. The damage that kills a phone usually isn't the splash itself – it's what happens in the minutes and hours afterwards, when trapped moisture, dissolved minerals and electrical power combine to eat away at the circuit board. The good news: if you act calmly and correctly in the first hour, many water-damaged phones can be saved.
Direct answer: If your phone has been in water, turn it off immediately and do not press any buttons. Take it out of the liquid, dry the outside with a soft cloth, remove the case and SIM tray, and leave it switched off somewhere cool and still. Do not charge it, do not use a hairdryer or any heat, do not shake it, and do not put it in rice. Then get it to a repair technician as quickly as you can – corrosion starts within hours, and a professional ultrasonic clean and board inspection before it sets in is the single biggest factor in whether your phone survives.
The first hour: exactly what to do
Work through these steps in order. The whole point is to remove power and moisture before they can do harm together. Stay calm – rushing is how people make things worse.
- 1. Get it out of the liquid straight away. The longer it sits submerged, the more water works past the seals. Lift it out cleanly – don't fish around.
- 2. Turn it off – and leave it off. If it's still on, power it down; if it's already off or unresponsive, leave it that way. A wet board with power running through it is where most permanent damage happens, so this step matters more than almost any other.
- 3. Don't press buttons or tap the screen. Pressing power, volume or home buttons can push water further inside and complete circuits you want left open. Resist the urge to "check if it still works" – checking is what damages it.
- 4. Dry the outside thoroughly. Wipe it down with a soft, lint-free cloth, paying attention to the charging port, speaker grilles and the gap around the screen. You're removing surface water so it can't seep inward.
- 5. Remove the case and pop out the SIM tray. Cases trap moisture against the body; ejecting the SIM tray opens a small drain path for trapped air and water. If your phone has a removable back or battery and you're confident, take those off too.
- 6. Keep it cool, flat and still. Lay it on a dry, absorbent cloth, screen up, at room temperature – not in a warm pocket. The aim is to stop moisture moving around inside while you arrange a proper repair.
That's it for first aid. Notice what's missing: any attempt to dry the inside yourself. You can't reach the board without opening the phone, and home "drying" methods do more harm than good – the real drying happens on a repair bench.
What never to do with a wet phone
Most water-damaged phones that end up beyond saving were made worse by well-meaning attempts to fix them. Avoid every one of these:
- Don't charge it. This is the big one. Plugging in a wet phone forces electricity through a board that may still have moisture and conductive residue across it – the fastest way to short-circuit components and trigger corrosion. Wait until it has been professionally cleaned and dried.
- Don't use a hairdryer, oven, radiator or any heat. Heat can warp components, melt the adhesives that seal the phone, damage the battery, and actually drive moisture deeper inside as it expands. Warm air feels productive but pushes water exactly where you don't want it.
- Don't shake, swing or blow into it. Shaking spreads water into areas it hasn't yet reached, and blowing into ports does the same. Keep it still.
- Don't put it in rice. The most popular myth of all – and it doesn't work. More on why below.
- Don't keep turning it on to test it. Every power-up is another chance for a short. If it survived, it'll still survive after a proper clean. If it didn't, repeated power-ups only deepen the damage.
Why the rice trick is a myth
Putting a wet phone in a bag of rice is the advice everyone has heard, and it's comprehensively wrong. Here's why.
Rice is a mediocre desiccant. It draws moisture slowly from the air immediately around it, but it has no way to pull water out from inside a sealed phone where the damage is actually happening – on the circuit board, behind the screen, inside the connectors. By the time rice has "dried" the outside (which a cloth does in seconds), corrosion on the inside has had hours to take hold.
Worse, rice creates its own problems: grains and starchy dust lodge in the charging port, speaker mesh and SIM slot, where they're a nuisance to remove. Manufacturers, including Apple, advise against the rice method for exactly this reason. Time in a bowl of rice is time the phone should have spent being properly cleaned – the worst of both worlds, with no real drying plus new debris.
Why speed matters: corrosion starts fast
Water alone rarely destroys a phone outright. The real enemy is corrosion, and it begins quickly. Tap water, rain, drinks and pool water all carry dissolved minerals and salts. When that residue bridges the tiny contacts on a circuit board – especially if any power is present – it triggers electrolytic corrosion, the same process that furs up a battery terminal, on a microscopic scale across delicate components.
It can start within hours and progress over days. A phone that powers on fine the morning after a spill can develop faults a week later as corrosion spreads: a dead charging port, a failing microphone, a flickering screen, or a board that won't boot. That's why "it still works, so I'll leave it" is risky – the window to clean a board before corrosion sets in is short, which is exactly why speed matters.
Salt water, drinks and other liquids
Not all spills are equal. Clean tap water is the gentlest case. Salt water (the sea), sugary or acidic drinks, coffee, and dirty or soapy water are far more conductive and corrosive, and leave residue that accelerates damage. The first-aid steps are the same – power off, don't charge, dry the exterior, get it to a technician fast – but the urgency is greater. Don't try to rinse or soak it yourself to "wash the salt out"; that's a bench job, and at home it usually adds more water than it removes. Tell the repairer what the liquid was – it changes how the board is cleaned.
When to get a professional involved (and what they actually do)
For anything more than the lightest splash, the next step is a technician, ideally before the phone is powered on again. On the bench, a liquid-damage service is very different from anything possible at home:
- Full disassembly down to the bare board, so every affected area can be reached.
- Ultrasonic cleaning in a bath with a specialist solution that lifts corrosion and conductive residue from places no cloth or air can reach.
- Inspection under magnification to catch early corrosion, lifted components and damaged traces before they cause failures.
- Component-level repair where needed – replacing a corroded connector or chip rather than writing off the whole phone, with your data and photos treated as the priority.
At celltech this is a mail-in service covering the whole UK, tracked and insured both ways, so you don't need a high-street repair shop for specialist liquid-damage work. Pricing is published up front rather than hidden behind a quote-wall, standard repairs include free diagnostics, and we cover around 2,467 device models with a 4.8-star rating.
A note on warranty: most standard celltech repairs carry a 27-month guarantee – more than double the 12 months most independent UK repairers offer. Liquid-damage and board-level repairs are inherently less predictable, so they carry our 120-day guarantee instead – still longer than many manufacturers' out-of-warranty cover, and honest tiering rather than over-promising on the hardest repairs.
As a rough guide to published pricing, a liquid-damage treatment on an iPhone starts at £44.95 on many models, with newer handsets costing more:
| iPhone model | Liquid-damage treatment (from) | Diagnostics |
|---|---|---|
| iPhone 11 | £44.95 | £24.95 |
| iPhone 12 | £44.95 | £24.95 |
| iPhone 13 | £44.95 | £24.95 |
| iPhone 14 | £119.95 | £24.95 |
| iPhone 15 | £119.95 | £24.95 |
| iPhone 16 | £44.95 | £34.95 |
| iPhone 17 | £149.95 | £44.95 |
These cover the clean-and-assessment stage; deeper component-level board repair is quoted after inspection, and you'll always be told the price before any work goes ahead. For the full published list, see our iPhone repair pricing.
Deciding what happens next: repair, recover or replace
Once the phone is in safe hands, there are three outcomes: it cleans up and works again, it can't be economically repaired but your data is rescued, or it's a write-off. Which makes sense depends on the phone's age and value, the extent of the corrosion, and whether the data matters more than the device.
Two further guides help you make that call without pressure. If you're weighing up whether to fix it, claim on insurance, or replace it, read water damage: repair, claim or write off?. If the phone is dead and your priority is getting your photos and messages back, see data recovery from a dead phone – both set out the realistic options honestly, including when the sensible answer is not to spend money on the handset.
Frequently asked questions
My phone still works after getting wet – is it fine?
Not necessarily. A phone can power on normally straight after a spill and then develop faults days later as corrosion spreads. If it was more than a light splash, it's worth having it cleaned and inspected while it's still working, rather than waiting for a fault to appear.
Does rice actually do anything?
No. Rice draws moisture only from the air around it and can't reach the water trapped inside a sealed phone, where the corrosion happens – and it sheds grains and dust into the charging port and speakers. A cloth dries the outside far better; the inside needs proper bench cleaning.
How long should I leave my phone to dry before turning it on?
Home drying can't reach the board, so "just leaving it" doesn't solve the real problem – it only delays it while corrosion continues. The safest approach is to keep it switched off and get it professionally cleaned before powering it on again.
Can I charge it once it looks and feels dry?
Please don't. The outside drying tells you nothing about moisture or residue on the board, and charging a board that isn't truly clean and dry is one of the most common ways a recoverable phone becomes a write-off. Have it cleaned first.
Is water damage covered by warranty?
Manufacturer warranties generally don't cover liquid damage, and a phone's internal liquid-contact indicators usually reveal whether it's been wet. Some home or mobile insurance policies do cover accidental liquid damage – our repair, claim or write off guide explains how to decide.
What does celltech's warranty cover on a water-damaged phone?
Liquid-damage and board-level repairs carry our 120-day guarantee – shorter than the 27-month guarantee on standard repairs like screens and batteries, because liquid damage is less predictable, but honest cover on the hardest kind of repair and longer than many manufacturers offer out of warranty.
Will I lose my data?
Often, no. If the board can be cleaned and the phone revived, your data is exactly where you left it. Even when a phone can't be economically repaired, data recovery is frequently still possible – see our data recovery from a dead phone guide.
How does the mail-in repair work?
You book online and post the phone to us with a tracked, insured service covering the whole UK both ways. We assess it, give you a clear price before any work begins, carry out the clean and any repair, and post it back to you fixed.
