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.
- 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.
- 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.
- 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.
- 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.
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. View Speaker Cleaner on the App Store
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 people ask
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.
