# What frequency ejects water from a phone speaker?

Apple does not publish a frequency that ejects water from an iPhone speaker. A low tone near 165 Hz is widely used by unofficial tools because it can vibrate a small speaker, but that number is a convention, not a specification, and no tone dries the inside of the phone.

## What to do

Treat any frequency claim with suspicion. The useful part is a low tone, played briefly, after the phone is unplugged and the grille is pointing down.

1. **Dry first.** Unplug cables, tap the connector downward, and wipe the outside. A tone does nothing for water still beaded on the glass, and it does nothing for a wet port.
2. **Play the tone from the phone itself.** Turn off Bluetooth audio. If Silent mode is on, the tone may not play. You should hear a low hum from the iPhone speaker.
3. **Use a low tone, not a blast.** Many unofficial water-eject tools use a tone around 165 Hz. Apple has never published that number for iPhone. Keep the volume at a level you can hear clearly, and keep the run short.
4. **Aim the grille down and stop if it strains.** Gravity helps. Stop immediately if the speaker rattles, distorts, or the phone warms up. Wipe drops that come out, then let the phone keep drying.

## What not to do

- Do not hunt for a 'secret Apple frequency.' iPhone has no water-eject button. Apple Watch plays tones when Water Lock turns off, and Apple does not publish that frequency either.
- Do not run a tone at maximum volume for minutes. A strained speaker can be damaged by the tone itself.
- Do not use rice, heat, or compressed air while you experiment.

If the speaker crackles when you are not playing a tone, or stays silent after the phone is dry, stop using tones and get the phone looked at.

## Where Speaker Cleaner helps

Speaker Cleaner is one of those tones, aimed at the grille. It is not an Apple frequency, and it will not clear liquid in the connector.

## Other ways

### Time and airflow

This is the method Apple documents. It is slower than a video of water spraying out of a grille, and it is the one that applies to the whole phone.

### Apple Watch Water Lock, for a Watch

Apple Watch ejects water from its own speaker when you turn Water Lock off. That feature is not on iPhone.

## Questions

### Is 165 Hz the best frequency?

Nobody has published a test that crowns one frequency. 165 Hz is a low tone people copy. A low tone may vibrate the grille. It is not magic, and it is not from Apple.

### Why does Apple Watch have a tone and iPhone does not?

Apple built Water Lock into the Watch. The iPhone support pages tell you to dry the phone. They do not include a tone.

### Will the right frequency fix a muffled mic?

No. Microphones and the charging port are separate from the speaker grille.

### Can the tone make things worse?

It can, if you drive a small speaker hard enough that it distorts or the phone gets warm. Stop when that happens.
