Sometimes Water Eject gets you 90% of the way there, and then there's that one last stubborn droplet giving everything a faint crackle. That's what this mode is for. It's the finishing move.
How to use it
- If the phone got wet, run Water Eject first.
- Lay the phone screen-up on a towel with the speaker at the edge, pointing down if you can manage it.
- Turn the volume all the way up and tap Deep Vibrate.
- Let three 20-second rounds run, wiping the grille in between.
Two kinds of shaking, working together
The sound itself. Instead of a smooth tone, this mode plays a square wave that steps through 60, 80, 100 and 120 Hz. A square wave gives the speaker cone sharp, sudden pushes rather than a gentle swing. That jolt is what dislodges the last drops a smooth 165 Hz tone can leave behind.
The vibration motor. Chrome and most Android browsers let a website buzz your phone's vibration motor, which shakes the whole phone body. The tool does that in time with the sound. iPhone browsers don't allow websites to touch the motor, so on an iPhone this mode is sound-only. It still does most of the work.
Quick phone vibration test
Not sure your vibration motor is even working? Tap the button below. You should feel a long buzz, a short one, then another long one. Feel nothing? Check that vibration is switched on in your Sound settings and try again.
When it's worth running
- The sound is much better after Water Eject, but still a little muffled.
- There's a crackle that comes and goes, which usually means a droplet moving around on the mesh.
- As the last step of a full clean, right before the speaker test.
Why a square wave instead of a smooth tone?
Picture pushing a swing. A smooth tone, a sine wave, is like a gentle, even push every time. A square wave is like giving the swing a quick shove, holding, then pulling back hard. The speaker cone moves to its end point almost instantly and stays there before snapping back. Those sudden starts and stops are what shake loose a droplet that's clinging to the edge of a hole.
That's also why this mode sounds harsher and buzzier than Water Eject. It's supposed to. The rounds are kept to 20 seconds so the speaker gets a rest between them.
The towel trick
Fold a dry towel two or three times and lay the phone on it, screen up, with the speaker end hanging just over the edge of the towel. When Deep Vibrate runs, the phone buzzes slightly on the soft surface instead of rattling on a hard table, and any water that comes out drips straight down instead of running back into the grille. It sounds like a small detail, but it noticeably helps with the last few drops.
The full cleaning order
- Water Eject, three rounds
- Deep Vibrate, three rounds, on a towel
- Wait 10 minutes
- Speaker test: Voice and Full sweep
- Still crackly? One more round of each, then let the phone dry for an hour
Questions people ask
What exactly is a vibration sound?
It's a low, pulsing tone that makes the speaker cone move in short, sharp strokes. Speaker cleaners use it to shake out water and dust that a smooth tone misses.
Why doesn't my iPhone vibrate during Deep Vibrate?
Apple doesn't let websites control the iPhone's vibration motor. The sound part still runs and does most of the cleaning.
Can vibration sound damage my speaker?
No. Each round is only 20 seconds and the notes are well within what phone speakers handle. Just don't leave it running for ages.
Can it fix a phone that won't vibrate?
No. If the vibration test does nothing on Android with vibration turned on, the motor or its connection may need a repair shop.
