Signs Your iPhone Has Water Damage (And What to Do)

Not sure if your iPhone has water damage? These tell-tale signs indicate liquid damage — and here's exactly what to do about it.

Water damage to an iPhone doesn't always announce itself immediately. In some cases, a phone that's been exposed to liquid will appear to work normally at first, only to fail catastrophically days or weeks later as internal corrosion progresses. Knowing the signs of water damage — both obvious and subtle — allows you to act quickly and protect your data before it's too late.

This guide covers every indicator of iPhone water damage, from the Liquid Contact Indicator used by Apple to the subtle behavioural changes that signal internal moisture damage.

The Liquid Contact Indicator

Every iPhone has a Liquid Contact Indicator (LCI) — a small adhesive-backed sensor that changes colour when it contacts water. In iPhones, it's located in the SIM card slot: a small dot or circle that is white or silver under normal conditions and turns red or pink when it has been wet.

To check: remove the SIM card tray. Using a small torch, look into the SIM card slot. A white or silver indicator means no water contact. A red or pink indicator confirms water damage. Note that Apple uses this indicator to determine warranty eligibility, though physical damage warranties changed with recent iPhone models.

Audio and Speaker Issues

Water damage often manifests first through audio symptoms. Muffled or distorted sound from the speakers or earpiece can indicate moisture in the speaker chambers. Crackling or popping sounds during calls suggest water in the earpiece. Reduced volume despite maximum settings is another common symptom.

Interestingly, the "Water Lock" feature on Apple Watch uses the speakers to expel water — but iPhones don't have this feature. Water that enters the speaker mesh gets trapped and can cause lasting damage if not properly addressed.

Charging and Power Issues

Water damage often disrupts the charging circuit. Signs include the phone refusing to charge, intermittent charging that works sometimes but not others, the phone charging slowly, or strange pop-up messages about liquid detection in the charging port (a feature on newer iPhones).

Modern iPhones (XS and later) include a liquid detection sensor in the USB-C/Lightning port. When liquid is detected, iOS displays a warning message and disables charging. This is a useful early warning system — if you see this message, take it seriously even if the phone seems to work otherwise.

Display and Touch Issues

Water under the display causes distinctive visual symptoms. Condensation inside the screen appears as a fogging or grey areas, particularly visible when the display is off and you look at it from an angle. Discolouration or dark spots under the screen indicate liquid accumulation. The touch screen becoming erratic or unresponsive in certain areas can also indicate moisture under the display glass.

These symptoms may appear hours or days after the water exposure as moisture works its way into the display assembly. If you notice any of these, have the device assessed immediately.

What to Do When You Spot Water Damage

Immediately power off the device — this is the single most important step. Do not attempt to charge it. Remove the SIM card. Place the device in a well-ventilated area (not in rice, not in the sun). Most importantly: contact a professional data recovery service as soon as possible.

If the phone still works, back up your data immediately via iCloud or iTunes before it potentially fails. But don't stop there — have it professionally assessed even if it appears functional, as corrosion can cause sudden failure without warning.

Frequently Asked Questions

What does the LCI indicator look like and where do I find it?

The Liquid Contact Indicator is a small dot or rectangle inside the SIM card slot. To see it, eject the SIM tray and look into the slot with a torch. White or silver = no damage. Red or pink = liquid contact has occurred.

My phone got wet a week ago and seems fine — is water damage still possible?

Yes. Corrosion from water damage can develop over weeks. A phone that appears fine initially may develop symptoms later. We recommend backing up immediately and having it professionally inspected even if it currently works.

Can water damage be prevented in future?

Use a good quality case with water resistance, avoid using your phone near water when possible, consider adding screen protectors that cover ports, and most importantly — ensure you have regular iCloud backups so data loss from any cause is minimised.

Is saltwater or freshwater worse for my iPhone?

Saltwater is significantly more damaging. Salt (sodium chloride) accelerates corrosion dramatically. Phones exposed to ocean water, pool water (which contains chlorine), or any other mineral-rich liquid need professional attention even faster than freshwater exposure.
