How to get water out of your phone speaker — what works and what doesn't

Your phone slipped into a bucket, got caught in the rain or went for a swim. It still works, but calls and music sound muffled, crackly or faint. Usually that is water sitting in the speaker grille — and the first few minutes decide how quickly it clears.

Do this first

1. Unplug it. Take out the charging cable and any headphones. Don't charge it while it is wet.
2. Dry the outside with a soft, lint-free cloth.
3. Tap it gently against your palm with the speaker and port facing down. Gravity does most of the work for loose drops.
4. Leave it in a dry spot with some airflow. A fan blowing cool air helps. Heat does not.
5. Salt water, pool water or a drink? Apple and Samsung both say to rinse the area gently with fresh tap water first, then dry it. Salt and sugar left behind can damage the parts.

Why a low tone helps the speaker

A speaker makes sound by moving a thin cone back and forth. Play a low tone — around 165 Hz — and the cone moves a long way with every pulse, a bit like shaking a wet umbrella. Drops sitting on the cone or in the grille get pushed out through the holes.

This is not a myth. Apple Watch has a built-in Water Lock that uses the same trick, and when repair site iFixit put dyed water into a phone and played a water-eject tone, water clearly came out of the speaker. The same test also showed its limit: it only clears the speaker area. Water that got further inside stays there.

Clear the speaker with a tone

1. Open Speaker Cleaner on the wet phone. It plays the tone in your browser — there is nothing to install.
2. Hold or lay the phone with the speaker facing down and set the volume to about 70%. Full volume isn't needed and can strain a small speaker.
3. Choose Water mode and a length — a minute is a good start — then press start. You may see tiny drops appear at the grille.
4. Play some music to check. Still muffled? Run one or two more rounds, then let the phone rest and dry for a while before trying again.

On an iPhone, check that the volume is up. If you hear nothing, turn off silent mode — older iOS versions keep web audio quiet in silent mode.

What not to do

When can I charge it again?

• iPhone: Apple suggests waiting at least 5 hours before charging with a cable after the phone gets wet. If you see a liquid-detection alert, let it dry with airflow — that can take up to a day.
• Samsung and many Android phones: a "moisture detected" warning blocks cable charging until the port is dry. Samsung says water usually evaporates within 1–2 hours.
• Wireless charging is an option on both — once the back of the phone is completely dry.

When it's more than the speaker

If sound is still crackly or quiet after a day of drying, or the microphone, screen or charging act up too, water has probably gone further than the grille. That needs a service centre, not more tones. Keep in mind that water resistance wears down with age and that liquid damage is usually not covered by warranty — the sooner it is checked, the better.

Once it sounds normal, run the Speaker & Headphone Test: play left and right, then the frequency sweep, and listen for rattles or a range that fades out early.
