iPhone 17 water damage repair in London: what to do first

If your iPhone 17 has been in water, unplug it, do not charge it, and let it dry in moving air for at least five hours before any cable goes near the USB-C port. If it still will not charge, will not switch on, or the display shows marks after a day of drying, stop experimenting and bring it to our bench inside Piccadilly Circus Underground Station for a free diagnostic, because every extra charge attempt on a wet connector adds damage you will pay to reverse.

What to do in the first ten minutes

The first ten minutes decide whether this is a drying job or a repair job. Work through these in order:

1. Pull every cable and accessory out. Apple says to unplug all cables and not to charge the device until it is completely dry, because using accessories or charging when wet might damage your iPhone [1].
2. Rinse it if the liquid was not water. Sea water, a drink or pool water leaves residue behind when it dries. Apple's instruction is that if a liquid other than water splashes on your iPhone, rinse the affected area with tap water, then wipe it with a soft, lint-free cloth [1].
3. Get the water out of the port. Tap the phone gently against your palm with the USB-C connector facing down to remove excess liquid [1].
4. Put it somewhere dry with airflow. Apple suggests a fan blowing cool air directly into the connector may help the drying process [1].
5. Leave the SIM tray shut. Make sure the iPhone is dry before you open the SIM tray [1]. Pulling it early gives water a second way in.

Then leave it alone. Resist the urge to switch it on and off every few minutes to check it; you learn nothing from that except whether it is still wet.

What not to do, and why each one costs you

The first hour is when well-meant fixes do the most harm. Avoid all four of these:

• Do not use heat. No hairdryer, radiator or oven. Apple says not to dry your iPhone using an external heat source [1].
• Do not use compressed air. Apple lists it alongside heat as something not to use [2].
• Do not poke the port. No cotton bud, no twist of paper towel. Apple warns against inserting a foreign object such as a cotton bud or a paper towel into the connector [1].
• Do not put it in rice. Apple says plainly: don't put your iPhone in a bag of rice, because small particles of rice could damage your iPhone [2].

Reading the liquid-detection alert

The iPhone 17 will tell you when the port is still wet. When you connect a USB-C cable or accessory, your iPhone can warn you if there is liquid in the connector, and charging and accessory connection stay unavailable until the connector, cable ends and accessory are dry [2]. Treat that alert as a measurement, not a nuisance.

Use it like this:

• Alert appears: disconnect the charging cable immediately [2]. Wait at least 30 minutes, then try again. If the alert returns, there is still liquid in the connector or under the pins of your cable [2].
• Alert keeps returning: give it up to a full day. Apple says it may take up to 24 hours to dry fully [2].
• Alert appears on one cable only, and the phone was never wet: the cable or accessory is the likely fault. Apple says if you see the alert every time you connect a certain cable or accessory, that cable or accessory may be damaged [2]. Swap it before you book anything.

Do not override the alert unless it is a genuine emergency. The phone offers an override, but Apple explains that if you charge your iPhone while the USB-C connector is wet, the pins on the connector or cable can corrode and cause permanent damage or stop functioning [2]. That corrosion is the difference between a phone that dries out and a phone that needs a new port. If you must have power, a wireless charger is still an option once the back of the phone is dry [2].

Muffled speaker after a swim: wait or worry?

A muffled speaker or microphone straight after water exposure is expected, not a sign of failure. Apple's check is to place the iPhone speaker side down on a lint-free cloth and see if water drips out, and it notes that water in the port may degrade speaker or microphone performance until it completely evaporates [1].

The decision rule is simple. If the sound returns to normal once the phone is fully dry, you are done. If it is still muffled, crackling or silent after 24 hours of drying, drying has not solved it, and that is a bench job. We handle that under our camera and speaker repair service.

Why the IP68 rating did not save it

The iPhone 17 is rated IP68 under IEC standard 60529, tested to a maximum depth of 6 metres for up to 30 minutes [1]. Those models were tested under controlled laboratory conditions [1]. Real life is different, and Apple is explicit about the gaps:

• Resistance fades. Splash, water and dust resistance are not permanent conditions, and resistance might decrease as a result of normal wear [1].
• Some exposures are outside the rating. Apple tells owners to avoid swimming or bathing with the phone, pressurised or high-velocity water such as showering, saunas and steam rooms, and dropping it or subjecting it to other impacts [1].
• Warranty does not cover it. Liquid damage is not covered under warranty, but you might have rights under consumer law [1].

If your phone has been dropped or is a few years into normal wear, do not rely on the rating: treat any water exposure as serious from the first minute.

When a water-damaged iPhone 17 needs a bench, not a fan

Drying deals with water that is still in the phone. It cannot undo corrosion, such as the pin corrosion Apple warns about when a wet connector is charged [2]. Bring the phone in if any of these are true after a full day of drying:

• It will not switch on, or switches on and restarts on its own.
• It will not charge on a known-good cable, even with no liquid alert showing.
• The display shows patches, lines or a blotch that was not there before. Water under the glass needs the display opened, which is work for our screen replacement team.
• The battery drains much faster than before, or the phone gets warm when idle. We check that under battery replacement and board diagnosis.
• Face ID, the cameras or the speakers behave differently from before the spill.

Do not keep charging a phone that shows any of these, and do not keep turning it on to check.

Protect your data before you do anything else

If the phone still switches on, back it up now, before the fault gets worse. Apple's reason for backups is exactly this situation: a backup gives you a copy of your information to use in case your device is ever replaced, lost or damaged [3]. An iCloud backup does not need a cable, so it avoids the wet port entirely.

If it will not switch on and there is no recent backup, say so when you come in. Recovering photos and messages from a liquid-damaged iPhone is a different job from getting the phone working again, and we assess both. Start with our data recovery service page to see what that involves, and read our guide on iPhone battery drain if the phone survived but its battery life did not.
