Eject the liquid the same way, but treat the device as needing professional attention afterwards. Salt and sugar leave conductive, corrosive residue when they dry, and that residue keeps damaging the board long after the speaker sounds normal.
Tap the button below. It plays a low‑frequency sound that vibrates the speaker and pushes trapped water and dust out of the grille. Turn your volume up to about 80%.
💡 Point the speaker downward so gravity helps the water escape. Repeat 2–3 times if needed.
This tool is optimized for Xiaomi devices. Select your exact model for the best results.
Dry the outside of your phone first.
Let gravity help pull the water out.
Ensure audio plays through the phone's internal speakers.
Never use earbuds. Turn volume up, but 100% isn't required.
Our tool is designed to target the three most common speaker issues using precise acoustic frequencies. Whether your phone took a dive or just sounds muffled from pocket lint, here is how we fix it.
Clear trapped water from your phone in about 60 seconds. The steady 165 Hz vibration physically pushes trapped liquid out of the speaker mesh.
A steady 165 Hz tone — the sweet spot for maximum diaphragm travel — physically pushes trapped water out.
Use our deep clean mode to act as a dust remover. Sweeping low frequencies shake loose stubborn dirt, sand, and lint.
Sweeps across low frequencies (120–400 Hz) to shake loose lint, dust and stubborn droplets the single tone misses.
Act as a volume booster for muffled speakers. Clear out blockages to restore heavy sound, loud bass, and crisp audio.
A clean 440 Hz reference tone so you can hear whether your speaker sounds clear again after cleaning.
Perfectly safe. These are ordinary frequencies your speaker already plays during music. The tool never exceeds normal listening levels — it just concentrates the energy at the frequency that moves water best.
Xiaomi's range spans genuinely sealed flagships and completely unsealed budget models, so checking what you actually have matters before assuming anything about water.

Dial *#*#6484#*#* to open the HyperOS or MIUI hardware test suite. It includes an isolated
speaker test that tells you whether each driver fires correctly — more reliable than judging by ear. Some builds
respond to *#*#4636#*#* instead.
Xiaomi flagships carry genuine IP ratings. Many Mi, Poco and Redmi models carry none, and some describe themselves as splash resistant, which reflects a coating rather than certified sealing. Look up your exact model rather than assuming the range is consistent — the difference between a sealed flagship and an unsealed mid-range model is substantial in practice.
Flagships use dual symmetrical speakers. Mid-range models typically have one real bottom driver plus an earpiece that assists. Budget models often have a single driver with a decorative counterpart grille housing a microphone. Cover each opening in turn while audio plays to establish which are real.
Inside the SIM tray slot. A white strip that has turned pink or red means liquid reached the internals.
Xiaomi's fast charging pushes high current, making a damp port a greater risk than on slower-charging devices. Do not override moisture warnings. Flagships with wireless charging can use it during the drying period; other models must simply wait 24 to 48 hours in moving air.
Settings → Sound and vibration includes sound effects and, on some models, Dolby processing. An update resetting these changes the audio character noticeably. Safe mode will also reveal whether a third-party equaliser app is holding the route.
Case off, brush the grille, Bluetooth fully off, volume 70–80 percent, grille facing down at about 45
degrees. Three cycles with brushing between each. Re-run *#*#6484#*#* afterwards to verify
objectively rather than by ear.
Eject the liquid the same way, but treat the device as needing professional attention afterwards. Salt and sugar leave conductive, corrosive residue when they dry, and that residue keeps damaging the board long after the speaker sounds normal.
Stop. If three cycles produce no improvement at all, the cause is not blockage. Check the symptoms on our guide to when a sound tool will not help, and have the device inspected rather than continuing to run cycles.
No. The frequencies used sit inside the range your speaker already reproduces whenever you play music, and the tool runs at moderate volume rather than maximum. The one genuine caution is earbuds: never run ejection tones into in-ear devices while you are wearing them.
No. Around 70 to 80 percent is the practical sweet spot. Maximum volume on a restricted diaphragm produces distortion rather than more displacement, and adds avoidable stress to the driver.
No — and this matters. The sound has to travel through the blocked speaker to do anything, so any connected Bluetooth or wired device defeats the purpose entirely. Disconnect everything first.
Our tool is great for water and dust, but it cannot fix physically blown speakers or electrical damage.
