The water eject shortcut is a user-created Siri Shortcut that plays a low-frequency tone (usually around 165 Hz) through the iPhone speaker to vibrate out trapped water. It replicates Apple Watch's Water Lock feature, which iPhone doesn't have natively. You install it through the Shortcuts app, then tap to run it when your speaker sounds wet.

Yes. The shortcut only plays an audio tone through the normal speaker — it doesn't modify system settings or hardware. At sensible volumes and short durations, there's no risk to the device. The main caveat is to avoid running the tone at maximum volume for many minutes continuously with water still present.

Open the Shortcuts app, accept the shortcut link from a trusted source, and add it to your library. Some versions require allowing untrusted shortcuts in Settings > Shortcuts. Once added, tap to run — the tone plays automatically. A purpose-built app like Water Remover avoids the setup and offers tuned presets.

Yes. The shortcut relies on standard speaker playback, which is available on every supported iPhone. It works the same on iPhone 15, 16, and 17, as well as earlier models. USB-C phones and Lightning phones both play the tone without issue.

A shortcut plays one tone and stops. A dedicated app like Water Remover offers multiple tuned tones, timing controls, guided workflows for different openings (bottom speaker, earpiece, charging port), and usually a cleaner UI. Both use the same underlying physics — the app just removes the setup work and gives you more control.
