Speaker Cleaner › Water Eject
Water mode · 150 to 200 Hz, up to 400 HzWater Eject: remove water from your phone speaker
Water Eject plays a low-frequency sound sweep, 150 to 200 Hz by default and 120 to 400 Hz on the Extended setting, that vibrates your phone's speaker and pushes water out of the grille. Hold the phone speaker-down at full volume and play one 30-second run. Most muffled sound after rain, a shower or a spill clears within one to three runs.
- Android and iPhone
- No app, no microphone
- Free
Turn media volume to maximum, disconnect earbuds and hold the phone with the bottom edge facing down.
Standard is the default because low frequencies move the speaker furthest, and that movement is what pushes water out. A 150 to 200 Hz sweep is the range a phone speaker can actually play loudly. Dust mode pulses the same 165 Hz tone.
Does your speaker sound clearer?
Ready. Tap Start cleaning.
Water in a phone speaker makes sound muffled, quiet or buzzy on bass notes immediately after the phone gets wet. Tilting the phone often changes the sound slightly, and droplets may be visible in the grille holes. The speaker is not silent, which separates trapped water from a hardware fault.
Signs there's water in your phone speaker
Water in a phone speaker makes sound muffled, quiet, or buzzy on bass notes, usually right after the phone got wet.
- Sound improves slightly when you tilt the phone.
- You can see droplets in the grille holes.
- Ringtones sound "underwater", but the speaker isn't silent.
How to eject water from your phone speaker
The same five steps work on Android phones and iPhones.
- Remove the caseWipe the phone dry so water can leave the grille freely.
- Turn media volume to maximumDisconnect Bluetooth earbuds so the sound plays through the phone.
- Hold the speaker facing downBottom edge down for the main speaker, top edge down for the call speaker.
- Press Start cleaningLet the 30-second run finish, then listen to the speaker.
- Repeat up to three timesStill muffled after three runs? Let the phone air-dry for up to 24 hours.
Water eject on Android (Vivo, Samsung, Redmi, Oppo, Realme)
Android phones play Water Eject through the bottom speaker in any modern browser.
- Open this pageIn Chrome or Samsung Internet. Disconnect Bluetooth earbuds.
- Volume to maximumTurn off "Adapt sound" or Dolby Atmos if they limit bass.
- Bottom edge downHold the phone so the speaker grille points at the floor.
- Press StartPlay up to 3 runs of 30 seconds each.
Water eject on iPhone
iPhone has no built-in water eject, unlike Apple Watch. Use Water Eject in Safari:
- Turn off Silent mode. Some iOS versions mute browser sound in Silent mode.
- Set volume to maximum and hold the iPhone bottom-down.
- Press Start and play 1 to 3 runs.
More detail: water eject on iPhone.
iPhones do not have a built-in water eject feature; only Apple Watch ejects water automatically when Water Lock is turned off. To clear water from an iPhone speaker, play a low-frequency water eject sound such as Speaker Cleaner's 165 Hz sweep in Safari at full volume, with the phone held speaker-down.
Water eject tools use a frequency near 165 Hz because a phone speaker's diaphragm travels furthest at low frequencies, and that movement pushes water out of the grille. Below about 150 Hz a small phone speaker produces very little output, so a 150 to 200 Hz sweep covers the usable range on most models.
The player offers two profiles. Standard sweeps 150 to 200 Hz. Extended sweeps 120 to 400 Hz, which can help on phones whose speakers produce very little output at 165 Hz, because a small speaker rolls off steeply below its own resonance. Standard is the default because lower frequencies move the diaphragm furthest and no published test shows the wider sweep performing better.
Why 165 Hz?
165 Hz sits near the low end of what a phone speaker can play loudly. Lower tones make the diaphragm travel further, which moves more water, but tones far below about 150 Hz are barely produced by phone speakers. A sweep from 150 to 200 Hz covers the sweet spot across different phone models.
Still muffled after 3 runs?
If the sound hasn't cleared, the next step depends on what you hear.
| Situation | Next step |
|---|---|
| Slightly better each run | Keep goingWait 10 minutes and run again. Water is moving. |
| No change at all | DryAir-dry for 24 hours, then test again |
| Crackling appears | StopDry for 24 hours, then see a service centre if it continues |
| Was salt water, tea or juice | RepairService centre; residue can corrode parts |
If a phone speaker is still muffled after three water eject runs, the remaining water is likely deeper than the grille. Leave the phone in a dry place with airflow for up to 24 hours, as Apple recommends, then run the water eject sound again. Crackling that continues after drying points to hardware damage.
