Dry a Phone After Liquid Exposure

Apple now tells you in writing not to use rice — and publishes the two waiting times that actually matter, one before you may try charging and one before the port is likely dry
ApplicabilityAny phone that has been splashed, submerged, or is showing a liquid-detection alert in its charging port. Written from Apple, Google and Samsung support documentation read on 2026-07-29, when Apple's 'If you see a liquid-detection alert on your iPhone' carried a Published Date of October 30, 2024 and 'Water and other liquid damage to iPhone or iPod isn't covered by warranty' carried May 26, 2026. Google's Pixel help articles and Samsung's Galaxy support articles carry no published date. Apple's published drying intervals were written for liquid detected in the connector; a phone recovered from full submersion is a more serious case, and Samsung's instruction for that case is to leave it off until a service centre has examined it. Where the manufacturers differ, both are named and neither is averaged.

BEFORE YOU BEGIN

Before you begin. This procedure is general reference information, not professional advice. Equipment varies by manufacturer, model, and year. Always follow the documentation supplied with your equipment — where it differs from this page, follow the manufacturer. Verify that you have the tools, the working conditions, and the ability to do this task safely. If anything is unclear, if the equipment is damaged, or if the task exceeds your experience, stop and use a qualified professional. You are responsible for your own safety and for the outcome. This site accepts no liability for any loss, damage, or injury arising from the use of this information.

Specifications marked unverified could not be traced to a manufacturer source. Do not rely on them — obtain the value from your equipment documentation.

Summary

The rice thing is wrong, and it is not this page saying so — it is Apple, in its own support documentation, in a list headed with things not to do. Apple's stated reason is not that rice fails to absorb water. It is that small particles of rice get into the phone and damage it. So the folk remedy does not merely waste a day of drying time you could have spent doing something that works; it introduces a second problem on top of the first one.

What replaces it is unglamorous and specific. Get the cable out, get the excess liquid out by tapping the phone with the connector pointing down, and then leave it somewhere dry with air moving over it. Apple publishes two intervals for what happens next: wait at least 30 minutes before you try charging at all, and if the phone still reports liquid, give it up to a day, because full drying can take 24 hours. The reason the waiting matters is corrosion — Apple states that charging through a wet connector can corrode the pins on the connector or the cable, and that the damage can be permanent. The alert is not the phone being fussy. It is the phone refusing to destroy itself.

Two things this page will not do. It will not print the location of the liquid contact indicator for your model, because Apple publishes that only as a per-model drawing and there is no text version to quote; you get sent to Apple's own table instead. And where Apple and Samsung give flatly opposite instructions — they do, on whether a cotton bud belongs anywhere near the port — it names both and sends you to your own manufacturer rather than inventing a compromise neither company published.

Terminology

This page uses one term for each item and holds it throughout, as ASD-STE100 requires. Equipment sellers and other guides use the names below for the same parts.

liquid contact indicator
Also called: LCI, water damage indicator, water sticker, red dot in sim tray, moisture sensor
liquid-detection alert
Also called: charging not available, liquid detected in lightning connector, liquid detected in usb-c connector, liquid or debris in usb port, water drop icon, moisture detected
connector
Also called: charging port, charger port, usb c port, lightning port
liquid exposure
Also called: water damage, dropped my phone in water, phone got wet, dropped phone in toilet, spilled water on phone

When to use a professional

Stop if liquid went inside the phone. Apple states that you must get help from an Apple Authorized Service Provider or an Apple Store as soon as possible. Apple also states that the warranty does not cover liquid damage.

Stop if the phone went fully into water. Samsung states that moisture can stay in the phone after it dries. Samsung states that it is best not to power on the phone until a service centre examines it. Take the phone to a service centre as soon as possible.

Stop if the phone is swollen or too hot to hold. Samsung gives an examination for these conditions. Google states that you must use a different phone, tablet or computer to ask for support.

Stop if the port looks burned, melted or corroded. Google states that this damage needs a warranty claim or an authorized repair partner.

Stop if you are not sure about the indicator. Apple states that you must speak to Apple or an Apple Authorized Service Provider for an examination, even when the indicator is red.

Common questions

Does putting a wet phone in rice actually work?

Apple says not to do it, and gives a reason that has nothing to do with absorption: small particles of rice could get into your iPhone and damage it. So the rice is not a neutral option that merely fails — it adds a second problem to the one you already have. It also costs you the thing that genuinely helps, which is air moving over a phone with the connector pointed down, starting immediately. Neither Google nor Samsung recommends rice anywhere in their own drying instructions either; both publish air drying instead. If you have already done it, get the phone out, check the port for grains under a light, and follow the steps on this page.

How long do I have to wait before charging a phone that got wet?

Apple publishes two figures and they answer different questions. Wait at least 30 minutes before you try charging at all. If the alert comes back when you try, there is still liquid in the connector or under the pins of the cable, and you should leave the phone in a dry area with airflow for up to a day, because it can take up to 24 hours to dry fully. You are allowed to retry charging at any point during that period, so you are not committed to a full day of waiting. Do not force it through: Apple states that charging a wet connector can corrode the pins and cause permanent damage.

Apple says never put a cotton swab in the port and Samsung tells me to use a cotton bud. Which one is right?

They genuinely contradict each other, and this page does not pretend otherwise. Apple's liquid-detection article says not to insert a foreign object such as a cotton swab or a paper towel into the connector. Samsung's water-damage article says to be thorough drying the places water can enter, including the charging port, and to use a cotton bud to ensure complete moisture removal. A cotton bud and a cotton swab are the same thing. Both are current, first-party instructions from the company that built the device, so the right answer is whichever one made your phone — not an average of the two, which is advice nobody published.

Where is the water damage indicator on my phone?

If it is an iPhone, Apple publishes the location per model in a table, and this page deliberately does not reproduce it. The reason is concrete rather than cautious: Apple gives that location only as a drawing for each model, one image per row, with no text version anywhere on the page — so there is nothing to quote and copying the diagram is not something we do. Go to Apple's table, find your exact model, and read the drawing. Note also that several recent iPhone models sold in some countries are eSIM-only, have no SIM tray, and therefore have no externally visible indicator at all.

The phone seems completely fine after getting wet. Do I still need to do anything?

Yes, at least the drying and the indicator check. Corrosion is slow, so a phone that survives the first evening can still fail weeks later, and Samsung specifically warns that moisture may still be present after a period of drying. The indicator check is worth doing while the event is fresh because it affects what happens if you later need a repair — Apple states that liquid damage is not covered by the standard warranty. Make a note of the indicator colour and the date. If the phone went fully under water rather than being splashed, Samsung's advice is to leave it off and have a service centre look at it regardless of how well it seems to be working.

Can I use a hair dryer on a cool setting, or compressed air, to speed it up?

No, and this is one of the few points where Apple and Samsung agree completely. Apple says not to dry the iPhone using an external heat source or compressed air. Samsung says that trying to dry the device rapidly with a hair dryer or hot air may damage it. Compressed air in particular tends to drive liquid and debris further into the phone rather than out of it. What both companies do endorse is moving air at ordinary room temperature — Samsung explicitly allows cool air from a fan, and Apple asks for a dry area with some airflow. A fan pointed at the phone is fine; heat is not.

Revision history

Current version 1 · updated 2026-07-29 · next review due 2027-07-29

  1. v1 · 2026-07-29First draft. Built from Apple, Google and Samsung support documentation opened by direct HTTPS fetch on 2026-07-29: Apple 'If you see a liquid-detection alert on your iPhone' (Apple Published Date October 30, 2024), 'Water and other liquid damage to iPhone or iPod isn't covered by warranty' (May 26, 2026) and 'How to clean your Apple products' (October 24, 2025); Google 'Fix Unplug charger or Liquid or debris message'; Samsung 'I dropped my device in water' and its Galaxy charging support article. The rice prohibition is attributed to Apple alone, because Apple is the only one of the three that names rice; Google and Samsung publish air drying without mentioning it, and no claim is made that they warn against it. Apple and Samsung publish opposite instructions on using a cotton bud in the connector; that is recorded as a conflict_note naming both and publishes as a consult-manufacturer instruction. The per-model liquid contact indicator location publishes as a consult-manufacturer instruction because Apple gives it only as a drawing, confirmed by parsing the table markup: every location cell is a single image with alt text and carries no text value.
