How to Eject Water from a Phone Speaker (Step-by-Step)

Here's the thing no one tells you about water-resistant phones: resistance isn't proof. An iPhone rated IP68 is designed to survive a dunk in shallow freshwater. That rating assumes fresh gaskets, no drop damage, and standing water — not pool water, not a hot shower, not a pint of beer, and not the ocean. A surprising amount of what people refer to as "my phone fell in water" is actually well outside the IP rating.

The first 30 minutes after water exposure decide whether you get your audio back quickly, slowly, or at all. This is a field guide.

What you should do in the first 60 seconds

Don't panic and don't dry the phone with a towel that presses on the grilles. The goal is to let gravity and surface tension work in your favor before water migrates deeper into the device.

1. Power the phone off if it's still on. A wet device drawing power can short internal contacts.
2. Shake the phone gently with the speaker grille facing downward. Three or four firm shakes is enough.
3. Set the phone vertical — screen up, charging port down — on a dry surface.
4. Leave it there for a few minutes before starting the eject routine.

What you're doing in those first 60 seconds is getting as much free water out as possible before forcing the rest out with sound.

The water-eject pulse explained

Modern phones can play a tone that moves the speaker diaphragm in large excursions at low frequency. When that happens, the diaphragm acts like a small pump: it compresses and rarefies the air in the speaker cavity, and water droplets migrate out of the grille along with the air pressure waves.

The effective frequency range is 150Hz to 175Hz, with 165Hz being the widely-used target. Lower frequencies move the diaphragm more but risk overheating the voice coil on small phone speakers. Higher frequencies move it less and don't eject water as efficiently.

The Apple Watch does this automatically when you activate Water Lock. Phones need you to run a tone manually. The mechanism is identical.

Step-by-step routine

1. Max the media volume. The eject pulse relies on the full excursion of the diaphragm. Half-volume means half-effective.
2. Hold the phone speaker-down over a towel. Both hands, gentle grip. The towel catches droplets as they come out.
3. Play a 165Hz pulse for 15 seconds. You'll feel strong vibration in your palm and likely see small droplets appear on the towel.
4. Wait 30 seconds. This lets capillary water inside the cavity redistribute toward the grille.
5. Play another 15-second pulse.
6. Repeat a third time. By the third pulse, if there's water left inside, it's no longer free — it's clinging to internal surfaces where a stronger pulse won't reach it.

Don't loop the pulse for a minute straight. Continuous low-frequency tones at full volume generate real heat in the voice coil, and you can cause damage exceeding whatever the water was going to do.

The 24-hour rule

After the pulse routine, the phone goes into a drying window. This is the step people skip, and it's the one that decides whether your speaker sounds crisp in a week or muddy forever.

Put the phone on a flat surface, preferably with a little airflow. Leave it for 24 hours. Don't charge it during this time. Don't run the eject pulse every two hours "just to check." The goal is to let residual humidity evaporate out of the speaker cavity through the grille.

If the room is humid, a desiccant can help — but the ubiquitous advice to use uncooked rice is wrong. Rice leaves starch residue in ports and doesn't actually reach the sealed speaker chamber. Silica gel packets (the ones that come with shoes and electronics packaging) are much better.

What sounds like water but isn't

Some things people attribute to "water in the speaker" are actually different problems:

• Muffling with no recent water exposure. Probably dust. Run a dust cleaning pulse instead.
• Crackling on specific frequencies. If you hear static only when the audio hits certain notes, that's usually a torn diaphragm, not moisture.
• Audio cutting in and out. Software routing issue. Check Bluetooth and force-close your apps.
• One speaker quieter than the other. Can be water, can be a cleaning issue on just one speaker. Run the routine, but also check if a case or screen protector is blocking one grille.

Running the eject pulse on a problem that isn't water won't hurt your phone, but it won't help either. The diagnosis step matters.

The gotchas no one mentions

A few realities about water exposure that get under-reported:

• Water-resistant doesn't mean pressure-resistant. Swimming with a phone, even an IP68 one, subjects it to pressure the rating doesn't cover.
• Hot water beats rated resistance. Hot tub, shower, kitchen sink with hot water running — all exceed the standard.
• Soap destroys the seal. Once soap gets past the gasket, water resistance is effectively gone. Apple won't warrant future water damage after soap exposure.
• Charge cycles while wet are the #1 killer. People dry the phone, plug it in immediately, and short the charging pins. If you must use the phone, run it on battery until it's fully dry.

If audio doesn't come back

Sometimes the eject routine and the drying window aren't enough. Signs you need service rather than another round of tones:

• Audio remains muffled or distorted after 48 hours of air drying
• The phone makes no sound at all through the main speaker
• You see discoloration behind the grille (greenish or brown tints indicate corrosion)
• The charging port shows the "liquid detected" warning that won't clear

At that point, Apple's repair diagnostic can tell you whether the speaker module or a broader internal component is affected. Third-party repair shops can swap the speaker module, often for much less than Apple, but you'll lose the water-resistance certification after reassembly.

Last thing

Phones aren't fragile the way they used to be, but they're not waterproof, either. The eject pulse works because it's fast and non-destructive, and because the water problem it solves — free liquid sitting in the speaker cavity — is a physics problem, not a chemistry problem. Once chemistry (corrosion) starts, no tone is going to help.

Run the pulse, air dry for a day, and most of the time you get your phone back exactly as it was. That's the whole trick.
