Does the iPhone have a built-in water eject feature?
No. The Apple Watch has Water Lock, which ejects water from its speaker with low tones after swimming, but Apple has never shipped the equivalent for iPhone. When an iPhone speaker gets wet, iOS may warn you about liquid in the charging port, yet it does nothing for the speaker itself.
Your two realistic options are a Siri Shortcut that plays an eject tone or a browser tool like this one. The browser route has the advantage of zero setup: no downloading a shortcut from an unknown author, no permissions, and it works the same on a friend's phone in an emergency.
Which iPhone speaker should face down?
The main loudspeaker fires out of the bottom edge of the iPhone, through the grille next to the charging port, so hold the phone upright with the bottom edge pointing at the floor while the tone plays. Recent iPhones also route audio through the earpiece at the top of the screen, which doubles as a second speaker for media.
If calls sound muffled but music is fine, the earpiece is the wet one. Run a session with the screen facing down instead, so gravity helps the earpiece drain. The speaker test mode alternates tones so you can hear which side is affected before and after.
How water resistant is an iPhone really?
Every iPhone since the iPhone 7 carries an IP67 or IP68 rating, which covers brief fresh-water immersion in lab conditions. That is why a rain shower or sink splash usually leaves nothing worse than a wet speaker grille: the seals keep water out of the internals while the grille itself holds droplets.
The rating is not a guarantee. Seals age, drops weaken adhesive, and pool or sea water is harsher than the fresh water used in testing. Apple's warranty also does not cover liquid damage. Treat the rating as crash protection, not an invitation, and treat a wet grille promptly.
Tips that make the eject session work better on iPhone
Take the case off first. Many cases lip over the bottom edge and create a pocket that traps water against the grille. Turn off Bluetooth or check that no AirPods are connected, because iOS will happily route the eject tone to your earbuds while the wet speaker stays silent.
Keep the volume around two-thirds and let the full session run. Afterward, play a voice note: speech is where water muffling is most obvious, so it is the quickest honest check.
- Remove the case and wipe the bottom edge dry.
- Disconnect AirPods and Bluetooth speakers before playing the tone.
- Hold the bottom edge toward the floor for the main speaker, screen-down for the earpiece.
- Use about 60-80 percent volume for 30-60 seconds.
- Verify with the speaker test mode or a voice note.
Step by step
- 1
Remove the case and disconnect Bluetooth
Take the case off, wipe the phone dry, and make sure no AirPods or Bluetooth speakers are connected so the tone plays from the iPhone itself.
- 2
Identify the wet speaker
If media sounds muffled it is the bottom loudspeaker; if calls sound muffled it is the earpiece. The speaker test mode helps you hear which.
- 3
Orient the wet speaker downward
Point the bottom edge at the floor for the loudspeaker, or lay the phone screen-down for the earpiece.
- 4
Play the sweep at moderate volume
Run the 165Hz-250Hz water eject sweep for 30-60 seconds at roughly two-thirds volume.
- 5
Test and repeat once if needed
Compare with the speaker test or a voice note, and run one more session after a short rest if audio is still dull.
