Water eject for iPhone

You can play the tone directly in Safari, but it is an independent browser tool—not a built-in Apple iOS feature.

Reviewed 6 October 2026

Quick answer: disconnect Bluetooth and headphones, hold the iPhone with the speaker opening downward, start at a comfortable volume, and run the tone. If exposed to liquid, review Apple's drying steps and do not connect a charging cable.

Water-eject tone

A gentle 165–230 Hz sweep generated on this device.

Ready to play

Begin at a comfortable volume. Stop if the sound is uncomfortable or distortion gets worse.

Hearing nothing?
  • On iPhone, turn off Silent mode; on Android, check the Media volume slider.
  • Raise the media volume with the side buttons while the tone is playing.
  • Disconnect other headphones or speakers unless that is the output you intend to test.
Sound played but nothing changed?

Stop repeating the tone if the speaker sounds the same or worse. A sweep cannot establish that the phone is dry or repair hardware damage. Continue with the wet-phone drying and repair decision guide.

Want the sound for offline playback? Download our original 30-, 60- or 90-second water-eject WAV and inspect its measured frequency plot. Only use a file when the iPhone is safe to operate. Sound cannot dry the charging port or the parts inside.

If your iPhone speaker is not working

First work out whether the problem affects every sound or only this browser tool. Disconnect AirPods, car audio and wired accessories, check the media volume, then try the phone speaker test and one familiar audio source. If both are silent or distorted, follow Apple's no-sound and distorted-sound checks. A water-eject sweep cannot fix audio routing, software or hardware failure.

If sound works but is reduced or unclear, use the muffled-speaker decision guide. If it crackles, buzzes or pops at moderate volume, use the crackling-speaker guide.

iPhone speaker only works on one side?

If one side seems silent during music or a left/right test, rule out the audio mix and route before you assume a speaker has failed. The iPhone's accessibility settings can shift stereo balance or combine the channels, and one listening test cannot identify a damaged part.

  1. Disconnect other outputs: turn off Bluetooth temporarily, unplug wired audio and make sure playback is coming from the iPhone.
  2. Compare both channels: on the left-and-right speaker test, play Left, Right, then Both at a comfortable volume. Repeat with familiar audio in another app. A phone may render the channels through its own speaker arrangement rather than as two speakers on opposite edges.
  3. Check the balance: open Settings > Accessibility > Audio & Visual and put the Balance slider in the center. Apple says this slider adjusts left-right stereo balance.
  4. Compare Mono Audio: switch Mono Audio on briefly. Apple says this sends the same content to the left and right speakers. If that changes what you hear, look at the source and balance settings. Mono Audio does not repair a speaker.
  5. Rule out a blocked opening: take off the case or film, and follow Apple's dry, soft-brush guidance only if the speaker or receiver opening looks dirty. Do not poke grille holes or add liquid.

If one channel stays silent in both the browser test and familiar audio, follow Apple's speaker troubleshooting and service path. If the issue is only the receiver during calls, compare speakerphone on and off in the call-audio steps. This page cannot tell you which component has failed.

Can't hear callers? (earpiece / receiver)

If you cannot hear someone during a call, check the call-audio route and in-call volume first. Comparing the receiver with speakerphone can narrow things down, but it will not tell you which part has failed.

  1. Check the call output: during the call, tap Audio and choose the intended destination instead of a Bluetooth headset or other connected output. Apple documents changing the audio destination during a call.
  2. Adjust in-call volume: press the side volume buttons while the call is active. Apple gives this as the volume control for a phone call.
  3. Compare receiver and speakerphone: switch the same call to speakerphone and back. Note which route sounds unclear instead of assuming the bottom speaker or top receiver has failed.
  4. Inspect the receiver opening: remove a case or film that covers it. If blocked or dirty, Apple allows a small, clean, dry, soft-bristled brush. Do not push anything into the opening.
  5. Check persistent routing: if calls repeatedly start on an unexpected output, review Settings > Accessibility > Touch > Call Audio Routing, the setting Apple documents for automatic call routing.
  6. Test the built-in speaker separately: move the Ringtone and Alerts slider in Settings > Sounds & Haptics. Apple says silence or a dimmed speaker icon there may call for service. A working alert sound does not by itself prove the receiver path works.

If incoming calls do not ring, that is a separate problem: check Silent mode and Focus/Do Not Disturb. Those are ring and notification checks, not the first active-call audio controls. If speakerphone is unclear too, your network, reception or the other person's connection may be involved. For a longer receiver-versus-speakerphone walkthrough, see the muffled-speaker guide's call-audio section.

iPhone speaker sounds quiet

Before treating a quiet speaker as a hardware fault, check the volume settings Apple documents for the built-in speaker.

  1. Check Volume Limit: open Settings, tap Sounds & Haptics, then under Built-In Speaker tap Volume Limit. If Limit Maximum Volume is on, the slider there caps how loud the speaker can play.
  2. Check Reduce Loud Sounds: still under Built-In Speaker in Sounds & Haptics, Apple says this setting softens loud sounds from the speaker, and turning it off stops that.
  3. Confirm which volume the buttons change: the side buttons adjust media volume while audio plays, and ringer or alert volume otherwise. If Change with Buttons is off in Sounds & Haptics, the buttons only affect media.
  4. Rule out routing: disconnect Bluetooth and wired audio, then confirm the built-in speaker, not headphones or a paired device, is the selected output.

If volume is still low after these checks, and the opening is clean with no case over it, treat it as a muffled or low-volume speaker problem rather than a settings issue.

iPhone speaker muffled with no recent water?

Do not start with a water-eject tone when there was no recent liquid exposure. A blocked opening, a case or film, audio routing, a call-path problem or a speaker fault can produce a similar symptom. Apple gives a dry inspection and comparison sequence for this case:

  1. Remove the case, film and screen protector: check that none covers the bottom speaker opening or the receiver at the top of the display.
  2. Inspect both openings under a light: if the speaker or receiver looks blocked or dirty, Apple permits a small, clean, dry, soft-bristled brush. Brush the opening gently; do not push debris inward.
  3. Keep cleaning dry: Apple says to avoid moisture in openings and not to use compressed air. A browser tone cannot remove or confirm compacted lint.
  4. Compare the built-in sound paths: in Settings, open Sounds & Haptics and move the Ringtone and Alerts slider. Then make a call and compare the receiver with speakerphone. This separates a calls-only issue from phone-wide playback.
  5. Compare one familiar recording: disconnect AirPods and car audio, then use the same moderate media volume and phone position. The speaker test gives you repeatable playback, but it cannot diagnose damage.

If every source stays muffled after the opening is clear, follow Apple's speaker troubleshooting and service path. If callers say your voice is muffled while playback sounds normal, use Apple's microphone checks instead.

iPhone Safari playback checklist

  1. Disconnect Bluetooth and wired audio: Make sure the sound comes from the iPhone's bottom loudspeaker, not nearby AirPods or car audio.
  2. Turn off Silent mode: If playback is silent, check Media volume and audio routing, and test with Silent mode off if needed. Behavior can depend on the browser and how playback is implemented.
  3. Remove a covering case: Take off a case if it covers an opening or holds visible moisture against the phone.
  4. Hold speaker downward: Keep the lower edge facing down over a soft, lint-free cloth while the audio runs.
  5. Start at normal volume: Start at a comfortable listening level. No fixed volume percentage is validated for every phone. Stop if the sound is uncomfortable or distorted.

Is water eject safe on iPhone?

A short tone is an optional listening test. Use it only when the iPhone is safe to operate, you start at a comfortable volume, and there is no liquid alert or abnormal behavior. It may move surface droplets at the speaker grille, but we have not established that it removes all water, dries the charging port or prevents internal damage. Stop if playback is harsh or distorted. If the phone is wet, follow Apple's liquid-exposure guidance before testing it.

Water-eject options on iPhone

“Water Eject” on an iPhone can mean three different things. None of these options is the Apple Watch control described above:

  • Browser tool: you can play the water eject sound in your browser without installing an app or granting microphone access. It is useful for one listening cycle when the phone is safe to operate.
  • Siri Shortcut: a third-party automation whose actions, permissions and audio can vary by shortcut version. Read the shortcut explainer before running one.
  • App Store app: an installed app may bundle a water-eject mode with subscriptions, ads, meters or other controls. Check the current listing and privacy label; our speaker-cleaner and water-eject app comparison records those differences.

Pick the browser when you want a quick, transparent playback test. Pick a shortcut or app only after you have checked what it does and what access or payment it asks for.

Liquid detected in the charging port on iPhone

If you connect a Lightning or USB-C cable to a damp iPhone, iOS can display an alert such as "Liquid Detected in USB-C Connector" (iPhone models with USB-C), "Liquid Detected in Lightning Connector" or "Charging Not Available." When this appears (this is a software alert, separate from the physical liquid contact indicator):

  • Unplug immediately: Do not tap "Emergency Override" unless in an actual emergency. Overriding the alert while pins are wet can cause permanent corrosion or connector damage.
  • Wireless charging alternative: Apple's liquid-alert page says you can still charge your iPhone with a wireless charger, and that for best results the back of the iPhone should be dry before it goes on a Qi-certified charger.
  • After liquid exposure: Apple says not to charge by cable or connect accessories until the iPhone is completely dry, and to allow at least five hours before doing so.
  • Liquid-alert retry: Apple's separate alert instructions say you can try charging again after at least 30 minutes. If the alert returns, disconnect the cable and leave the iPhone in a dry area with airflow; it might take up to 24 hours to dry fully. The 30-minute retry is not confirmation that the phone is dry. Do not use Emergency Override unless it is a true emergency.
  • If the phone and cable are dry: Apple says a recurring alert with one cable or accessory can mean that accessory is damaged. An alert with every Apple cable or accessory may need service.

Liquid detected, but the iPhone isn't wet?

Moisture can sit in the port or under the cable pins where you cannot see it, so a phone that looks dry does not prove the alert is wrong. Unplug, leave the iPhone in a dry area with airflow and retry after at least 30 minutes, as Apple describes. Then narrow it down the way Apple does: if the alert appears every time with one particular cable or accessory, that cable or accessory might be damaged; if it appears with every Apple Lightning or USB-C cable or accessory, the iPhone might need service. Do not insert anything into the port to check for water.

How long does Liquid Detected last?

Apple does not give a fixed time for the alert. Its guidance is to try again after at least 30 minutes, and it says the iPhone might take up to 24 hours to dry fully. Separately, after liquid exposure Apple says to allow at least five hours before charging by cable or connecting accessories. If the alert keeps returning beyond that window with every Apple cable, treat it as a service question rather than waiting longer or using Emergency Override.

iPhone water damage indicator (liquid contact indicator)

Two different signals get called a "water sensor" or "water damage indicator". One is the physical liquid contact indicator (LCI), a small indicator that Apple says is normally white or silver and turns fully red when it contacts water or a liquid containing water. The other is the software Liquid Detected alert, which Apple describes for the charging connector, cable or accessory. They are separate, and a sound sweep on this site does not read, test or reset either one.

Does my iPhone have a water sensor?

The Apple pages used for this section describe the LCI and the connector alert. Neither describes a moisture sensor reading you can open in iOS, so the software signal Apple documents is the alert, not a number or a status screen.

How do I look at the indicator?

Where the LCI sits depends on the model. Apple's page has a table with a picture for each iPhone, so find your model there. Apple also says some models sold in certain countries or regions support eSIM only and have no SIM tray or externally visible LCI. To see an LCI, Apple suggests a lighted magnifying glass, angling the light or the device. If Apple's table shows that yours is reached through the SIM tray opening, Apple's SIM page says to insert a paper clip or SIM-eject tool into the hole beside the tray and push toward the iPhone, but not to force it. If the tray resists, Apple suggests asking your carrier or an Apple Store instead of pushing harder. Do not put anything else into an opening.

What does a triggered indicator mean?

Apple says an LCI activates when it contacts water or a liquid containing water, and that it will not activate from humidity and temperature changes within the product's environmental requirements. Apple also says service for liquid damage to an iPhone is not covered by the Apple One-Year Limited Warranty, and its water-resistance page adds that you might have rights under consumer law. A red indicator is a sign of liquid contact. It does not tell you which part is affected, whether the speaker is damaged, or whether a repair will be offered. For a muffled speaker, follow Apple's drying guidance below and use Apple authorized service if sound stays poor.

Apple's official drying guidance

Apple's liquid-exposure support documentation says to tap the iPhone gently against your hand with the connector facing down to remove excess liquid, then leave it in a dry area with airflow. Water in the speaker grille or microphone can cause audio to sound muffled until it fully evaporates.

For step-by-step instructions on safe drying times, non-water spills and myths like rice bags, see our complete wet-phone guide.

When to seek Apple authorized service

A sound sweep cannot fix water that has got past internal seals or damaged the speaker driver. Get professional service if your iPhone gets unusually warm, the camera lenses fog up inside, or sound is still distorted after you follow Apple's drying instructions.
