It always happens at the worst moment. The phone slips into the sink, a glass tips over on the table, or you forget it's in your pocket at the pool. You fish it out, it still turns on (relief), and then you play a video. The sound is muffled, crackly, a bit like someone talking through a pillow.
In most cases this is just water sitting in the speaker grille, and it comes out on its own with a little help. The steps below are in the order that matters most.
First 10 minutes: what to do right away
- Take the case off. Cases trap water against the bottom edge of the phone, right where the speaker and charging port are.
- Wipe the outside dry with a soft, lint-free cloth. Don't push the cloth into the holes.
- Hold the phone speaker-side down and tap it gently against your palm a few times. Gravity does a surprising amount of the work.
- Don't charge it yet. Water in the charging port plus electricity is the one combination you really want to avoid. Apple's own guidance for iPhones is to wait at least 30 minutes, and longer if the liquid warning comes back.
- Leave it somewhere dry with a bit of airflow, like near a fan on a low setting. Not on a radiator, not with a hair dryer on hot.
Push the water out with sound
A speaker makes sound by pushing a thin membrane back and forth. Play a low tone around 165 Hz and that membrane moves much further than it does with normal music, which physically pushes droplets out through the grille. Apple Watch uses the same idea for its Water Lock feature.
You don't need to install anything for this. Open Fix My Speaker, turn your volume all the way up, hold the phone speaker-side down and press Start. It plays a 30-second tone. You might actually see tiny droplets on the grille or on the table.
Run it two or three times. If the sound is clearer after each round, you're on the right track.
Quick tip: if your phone fell in something sticky like juice or soda, water isn't the only problem. Wipe the grille with a slightly damp cloth first, then dry it, then use the tone.
Why you shouldn't put your phone in rice
Rice is the advice everyone's uncle gives, and it's probably the most repeated phone myth there is. Apple's support page on liquid detection now says plainly not to put an iPhone in a bag of rice. Rice doesn't dry a phone faster than open air does, and small bits of rice and starch dust can get into the charging port and speaker grille, which is the last thing you want in there.
The same goes for silica gel packets inside a sealed bag. They're not harmful, but they won't beat a dry room with moving air.
Things that make it worse
- Hair dryers on high heat. Heat can damage the battery and the adhesive that keeps the phone water resistant.
- Cotton buds or paper towels pushed into the holes. They leave fibres behind and can push water further in.
- Blowing into the speaker. Your breath is moist. You're adding water, not removing it.
- Opening the phone yourself. Modern phones are glued shut. Opening one usually breaks the water seal for good.
How long until it sounds normal?
If it was a quick splash, the tone method plus an hour of drying is usually enough. A proper dunk can take up to a day before every last droplet evaporates. The sound often improves in stages: crackly, then slightly muffled, then normal.
When it's not just water
Some signs that it's time for a repair shop rather than another round of tones:
- The sound is still muffled after 24 hours of drying.
- One speaker works and the other is completely silent.
- You hear rattling or buzzing even at low volume.
- The phone was in salt water or a pool and it's been more than a day. Salt and chlorine can corrode the speaker over time.
Not sure if the speaker is really fixed? Run a quick speaker test. Play the bass and treble tones and listen for buzzing or crackling. Clean tones mean you're good.
How the tone on this site works
We built Fix My Speaker around two modes. Water mode plays a steady 165 Hz sine wave for 30 seconds. Dust mode sweeps slowly between roughly 120 and 400 Hz, because a changing frequency shakes loose particles that a single tone can miss. The sound is generated live in your browser with the Web Audio API, so nothing is downloaded or uploaded. It can't fix a damaged speaker, and it isn't a substitute for drying time, but it does clear the droplets that cause most of the muffling.
The short version
Case off, wipe it, tap it face down, don't charge it, and play a 165 Hz tone a few times. Skip the rice. Most phones bounce back completely, and you'll have a new party trick for the next time a friend drops theirs in the pool.
