Tap the button above, then hold the phone speaker-side down over a towel. You may see fine droplets appear on the mesh.
Repeat once or twice if needed. Do not charge until the device and charging connector are completely dry. Follow the device manufacturer's guidance.
Water clings to the fine mesh of your speaker grille through surface tension — the same force that lets a droplet hold its shape on a flat surface. Trapped water muffles sound, adds crackle, or can block the speaker almost completely.
Low frequencies move a speaker cone farther than typical speech does, which may help move droplets trapped against the speaker grille. At 165Hz, the cone moves 165 times per second, but speaker designs and results vary by device. Apple Watch uses a device-specific series of tones to clear water from its own speaker; that does not validate this 165Hz tone for every phone.
Is it safe? No single tone is guaranteed safe or effective across every phone. Start at a moderate volume, increase it gradually only while playback remains clear, and stop if you hear distortion or unusual sounds. This tool does not dry the charging connector or the inside of the device.
A low-frequency tone may help move water trapped in some iPhone speaker grilles, but results vary by device. Apple does not document this third-party 165Hz tone as a universal iPhone feature; follow Apple's liquid-exposure guidance.
A low-frequency tone may help on some Samsung Galaxy and Android phones, but results vary by device and speaker design. Start at a moderate volume and stop if you hear distortion or unusual sounds.
Start with 30 seconds, then stop and check the speaker. Repeat once or twice only while playback remains clear; stop if you hear distortion or unusual sounds.
No single tone is guaranteed safe or effective across every phone. Start at a moderate volume, increase it gradually only while playback remains clear, and stop if you hear distortion or unusual sounds. Results vary by device.
A tone only addresses water at the speaker grille; it cannot make a submerged phone dry or safe to charge. Do not charge until the device and charging connector are completely dry. Follow the device manufacturer's guidance, and seek qualified service if the phone is damaged or malfunctions.
