Water eject a low tone to shake water out of your speaker

How to eject water from your phone speaker with sound

To push water out of a phone speaker with sound, lay the phone speaker side down, set the volume high and play a loud low tone for 30 to 60 seconds, then let the phone dry. Gravity does part of the work and the vibrating speaker does the rest. The tool on this page plays a low tone (165 Hz by default, adjustable from 100 to 300 Hz) that pulses for 6 seconds and then sweeps for 4 seconds, repeated for 15, 30 or 60 seconds.

The order of steps matters more than the tone itself. Dry the outside first, then let the sound shake the grille, then leave the phone alone to finish drying.

• Wipe the phone with a soft, lint-free cloth and take it out of its case so the speaker grille is open.
• Unplug any cable. Do not charge it while it is wet.
• Open this page in the phone's own browser, so the sound comes from the wet speaker, not from another device.
• Lay the phone on a lint-free cloth with the speaker grille facing down, or hold it with the grille pointing at the floor.
• Turn the media volume up and press Play. Watch the cloth: small drops on it mean water is coming out.
• Run it two or three times with short breaks. If one setting barely makes a sound, try a higher frequency such as 200 Hz.
• Then leave the phone in a dry place with some airflow. The speaker may stay a little muffled until the last water evaporates.

Does water eject actually work?

Water eject can shake loose droplets out of a speaker grille, and that is all it can do. The physics is simple: a speaker makes sound by moving a thin membrane back and forth, and a loud low tone moves it much further than a high tone does. That movement pushes on the air and on any water sitting in the small openings in front of it. With the speaker facing down, gravity carries the loosened drops away.

No study has tested sound for removing water from phone speaker grilles; a search of the Europe PMC research database on 1 October 2026 found none. So the mechanism is plausible physics, not a measured result. Apple's own watch uses tones for the same job, but nobody has compared a tone with simply leaving the phone to dry.

What water eject cannot do matters more. It does nothing for water inside the phone, in the charging port, behind the screen or around the battery. Apple notes that water in the speaker or microphone "might degrade speaker or microphone performance until it completely evaporates", which means time and air are the real fix. Treat the tone as a first step for a muffled speaker after a splash, never as a repair for a phone that went under water.

Why 165 Hz? Where the water eject frequency comes from

The 165 Hz figure has no official source. It circulates on social media, Reddit and water-eject websites, usually described as imitating the Apple Watch tone, but Apple does not publish the frequency of the watch's tones, and neither Apple, Google nor Samsung recommends any tone for phones. Nobody has traced 165 Hz to a specification or a measurement.

It is still a sensible kind of number. A tone of 165 Hz vibrates 165 times a second, so each cycle lasts about 6 milliseconds, and its wavelength in air is about 2.1 metres. It is low enough to make the membrane swing widely, yet high enough that a small phone speaker can still play it. That second point is the catch with lower settings: phone speakers are tiny and reproduce deep bass weakly or not at all, so a 100 Hz tone may come out faint on one phone and clearly on another.

That is why the tool lets you move between 100 and 300 Hz. A good rule is to pick the lowest frequency your phone plays loudly. If 165 Hz sounds thin, go up; if a lower tone makes the phone buzz in your hand, that is the membrane moving a lot, which is exactly what you want.

The pulse and the sweep have a purpose too. Pulsing on and off gives the membrane repeated pushes instead of one steady hum, and the sweep moves through nearby frequencies so that whichever one the speaker and its grille respond to best gets played. Neither design has been tested in a study; they simply avoid betting everything on a single number that nobody has verified.

Apple Watch Water Lock: the official water eject

Apple Watch is the one device with an official water-eject function. According to Apple Support ("How to use Water Lock and eject water from your Apple Watch", published 17 September 2026), Water Lock turns on automatically when you start a water workout, such as a swim.

To turn it off, press and hold the Digital Crown until the display says Unlocked; on watchOS 8 or earlier you rotate the Digital Crown instead. In Apple's words, "A series of tones plays to clear any water that remains in the speaker."

Apple does not say what frequency these tones use, and that gap is where the 165 Hz figure grew up. The important point is that Apple built this for the watch only. For iPhone, Apple's advice is physical: tap, drain, air and wait.

What to do if your iPhone gets wet: Apple's advice

Apple's support page "About splash, water, and dust resistance of iPhone 7 and later" (published 14 July 2026) tells you to tap a wet iPhone gently against your hand with the Lightning or USB-C connector facing down, to remove excess liquid. Then leave it in a dry area with some airflow. Apple adds that a fan blowing cool air directly into the connector might help.

Do not dry it with an external heat source, and do not insert a foreign object such as a cotton swab or a paper towel into the connector. Unplug all cables and wait at least 5 hours before charging with a cable or connecting an accessory.

For a muffled speaker, Apple suggests placing the iPhone speaker side down on a lint-free cloth to see whether water drips out. That is the same position you use with a water-eject tone, so the two fit together: the tone shakes, the cloth catches, and the waiting does the rest.

Two more facts from the same page are worth knowing before you take a phone near water at all. Liquid damage is not covered under the iPhone warranty, and water resistance is "not permanent": it may decrease as a result of normal wear.

How to dry a wet Android phone: Google Pixel and Samsung Galaxy

Google's advice for a Pixel that falls into water is to lift it out, turn it off, dry it with a soft cloth and set it on a flat surface to finish drying at room temperature. Google also notes that water damage is not covered by the warranty. Its help page says nothing about removing water with sound.

Samsung's support page "How water resistant is a Galaxy phone?" (updated 22 June 2026) says to wipe the phone with a soft cloth and not to connect chargers or accessories until it is completely dry. It warns that call audio may be affected while the microphone, speaker or receiver is damp. Samsung also lists what not to use: heating devices, soap, detergents, abrasives, compressed air or ultrasonic cleaners. It, too, mentions no sound-based water ejection.

So on Android the picture is the same as on iPhone: the manufacturers rely on wiping, waiting and keeping the charger away. A water-eject tone can sit between the wipe and the wait, as long as you play it from the phone's own speaker and do not plug the phone in to keep it running.

What not to do with a wet phone

The official pages agree on three things: no heat, no charging while wet, and nothing poked into the port. Here is what each manufacturer says, side by side.

Note what is not on the list: none of the three manufacturers suggests any household trick for drying a phone. If the phone was fully submerged, or it shows signs of trouble beyond a muffled speaker, follow your manufacturer's support channel rather than any tone or internet remedy.

What IP67 and IP68 mean for water resistance

An IP rating has two digits defined by the international standard IEC 60529. The first rates protection against solids, from 0 to 6, where 6 means no ingress of dust. The second rates protection against liquids, from 0 to 9, where 9 is protection against high-pressure hot water. So in IP68, the 6 means dust-tight and the 8 is the second-highest water rating.

The digits do not tell you a depth on their own; the manufacturer states the depth and time it tested. Apple rates iPhone 12 to iPhone 17 models IP68 to a maximum depth of 6 metres for up to 30 minutes, and iPhone 7, 8, X, XR and SE (2nd and 3rd generation) IP67 to 1 metre for up to 30 minutes. Samsung describes its IP68 phones as water resistant to 1.5 metres for 30 minutes.

Water resistant does not mean waterproof for daily swimming. Apple still advises against swimming, bathing, showering or intentionally submerging an iPhone, says water resistance may decrease with wear, and does not cover liquid damage under warranty. A high rating explains why most phones survive a splash with nothing worse than a muffled speaker, which is exactly the situation a water-eject tone is meant for.

Is there a water eject shortcut for iPhone?

Apple does not offer a water-eject tone or shortcut for iPhone. The water eject shortcuts and apps you find online are made by third parties, and the ones that state a frequency usually use the same unofficial 165 Hz figure as water-eject websites, described as a copy of the Apple Watch tone.

A web page does the same job without installing anything: it plays the tone through the phone's own speaker, as long as the page is open on the wet phone itself and the media volume is up. If you hear nothing at all, check that the media volume is not muted.

Whether the tone comes from a shortcut, an app or a browser, it works on the same principle and has the same limit: it can move water in the speaker grille and nothing deeper.

Is water eject safe for my speaker and my ears?

A water-eject tone is meant to be loud, so keep it short and keep the phone away from your ear. The tool stops on its own after 15, 30 or 60 seconds, and two or three runs are plenty. If the speaker rattles harshly or the sound distorts badly, lower the volume a little or move to a higher frequency; a buzz in your hand is fine, a crackle is the speaker straining.

For your ears, the World Health Organization warns that "even a one-time exposure to extremely loud sound can damage your inner ear cells". A phone lying face down on a table is not that loud at a normal distance, but do not hold the speaker against your ear to check whether it is clear. Listen at arm's length instead.

Low tones also play a trick on the ear. The international equal-loudness standard (ISO 226:2023) shows that deep tones need far more sound pressure to sound as loud as mid tones, so a 100 Hz or 165 Hz tone can seem quieter than it really is. That is one more reason not to press it against your head.

If the speaker still sounds muffled after a few runs, stop playing tones and give it time. Apple says water may degrade speaker performance until it completely evaporates, so a dry place with some airflow and a few hours of patience will do more than another minute of sound.
