Wet phone, dull sound

How to Get Water Out of an iPhone Speaker

Your speaker sounds like it is under a blanket. This is the routine that works, in order, plus the four popular remedies that make the problem worse.

The routine

  1. Take the case off and dry the outside

    Wipe the phone with a lint free cloth, including the edges. A case lip sitting over the speaker holes will catch anything the tone pushes out and hold it there.

  2. Tap the phone gently, ports facing down

    Apple's own advice for a wet iPhone: tap it against your hand with the connector pointing down to shake the loose drops out. Do this before any sound.

  3. Turn the volume up and lay the phone speaker down

    On a dry towel or cloth. The tone has to move the speaker membrane, and at low volume it barely will. Gravity should pull in the same direction.

  4. Play a low, pulsed tone for about ten seconds

    This is the part Water Eject does. It plays bursts that slide between 150 Hz and 220 Hz, 700 milliseconds of sound followed by 300 milliseconds of silence, for about eleven seconds. The silence matters: each burst starts from rest and hits harder than a continuous tone.

  5. Listen, and repeat if you need to

    Play a voice memo or a song. If the sound is still dull, run it once more after the short pause the app enforces. Two or three runs is normal. Ten is not going to help.

  6. Leave it in dry air

    Somewhere with airflow, at room temperature. Apple says to wait at least 30 minutes before charging and that a phone can need up to 24 hours to dry out fully.

One tap, about eleven seconds.

Why a low tone moves water and a high one does not

The eject tone: bursts of 700 milliseconds separated by 300 milliseconds of silence, while the pitch rises from 150 Hz to 220 Hz and back
One Water Eject run, read left to right. The blocks are sound, the gaps are silence: 700 milliseconds on, 300 milliseconds off. Underneath, the pitch slides from 150 Hz up to 220 Hz and back, two and a half times over about eleven seconds. Values read from the app source.

A droplet stays in the grille because surface tension holds it against the mesh. To get it out you need the speaker membrane to travel a long way, which is what low frequencies do: the same power at 180 Hz moves the membrane far further than it does at 4 kHz. Push enough air through the opening and the droplet loses its grip.

This is not a trick. Apple Watch models with Water Lock clear their own speakers exactly this way when you turn the lock off. The iPhone has no equivalent built in, which is why third party tone apps exist at all.

The pulsing is the second half of the idea. A continuous tone settles the membrane into steady motion. Bursts separated by silence make it start and stop repeatedly, and the leading edge of each burst is the part that dislodges a droplet.

Four things that make it worse

Popular advice that Apple and repair technicians warn against.
RemedyWhat actually happens
A bag of riceApple advises against it. It does not draw water out of a sealed phone, and rice dust and starch get into the grille and the charging port, where they stay.
A hair dryer or radiatorHeat drives moisture further inside and stresses the battery and the adhesive seals. Apple says not to use an external heat source.
A can of compressed airPushes water and dust deeper into the mesh instead of out. A hand squeeze bulb is the gentle version, and even that goes near the grille, never against it.
Charging straight awayA wet connector can corrode when current runs through it. Apple asks you to wait at least 30 minutes, and longer if the liquid detection alert appears.

When to stop and get it looked at

A tone reaches the speaker opening and nothing beyond it. Stop trying and go to a technician if the phone was submerged for more than a moment, if the liquid was sea water, pool water or a sugary drink, if the screen shows lines or discolouration, if the phone will not charge, or if it keeps showing the liquid detection alert after a day in dry air. See the first hour checklist for the wider triage.

If the sound stayed dull but the phone was never wet, you are probably looking at dust in the grille or one of the settings covered under muffled sound.

Questions

How long does it take to get water out of an iPhone speaker?

One run of the tone lasts about eleven seconds, and most phones sound clearer after one or two runs. The phone itself takes longer: Apple says a wet iPhone can need up to 24 hours in dry air before it is fully dry inside, and asks you to wait at least 30 minutes before plugging in a cable.

Does putting the iPhone in rice get water out of the speaker?

No, and Apple advises against it. Rice does not pull water out of a sealed phone, and small particles of rice can get into the speaker grille and the charging port and make things worse. Dry air and time do the work.

Why does my iPhone still sound muffled after the water is out?

Two common reasons. Water left mineral or soap residue on the grille mesh as it dried, which a dust program can sometimes loosen. Or the muffling was never water at all but pocket lint, a case lip over the speaker holes, or a volume limit setting. Run the per side speaker test to see whether one side alone is affected.
