Your iPhone survived a splash, but now the speaker sounds muffled, quiet or crackly. In most cases that's water sitting in the speaker grille, and it clears as it evaporates. Here's what Apple suggests, what you can safely try, and when it's time to get help.
Key takeaways
- Water in the speaker grille can take hours to evaporate. Leave the phone to air dry, speaker side down on a lint-free cloth.
- A low-frequency tone at moderate volume can help push out droplets.
- Lint or dirt in the grille can also muffle sound. Use a soft, dry, clean brush, never sharp objects.
- Still bad after a day? Contact Apple Support or an authorized service provider.
Why water muffles the speaker
iPhone speakers sit behind tiny openings in a mesh grille. Water can bridge those openings and dampen the sound until it evaporates. Apple's support page says water in the port "might degrade speaker or microphone performance until it completely evaporates." That's why the problem is usually temporary.
Step 1: Give it time
Water in the grille can take hours to evaporate. Apple suggests placing your iPhone speaker side down on a lint-free cloth and checking whether water drips out. Then leave it in a dry area with some airflow. A fan blowing cool air can speed things up.
Step 2: Try a low tone
Playing a low-frequency tone at moderate volume can help push out droplets. Use a speaker-cleaner app, a trusted shortcut or a tone video, in 10- to 30-second bursts with the speaker facing down. See do water eject sounds work? for how and why.
Step 3: Check for debris
Lint or dirt in the grille can also muffle sound. A soft, dry, clean brush can help. Don't use sharp objects. Pocket lint, makeup and dust build up over time, especially in the bottom speaker and the earpiece at the top of the screen.
Safe cleaning steps
- Turn the phone off and remove the case.
- Use a soft, dry brush, such as a clean, soft-bristled toothbrush, and brush gently across the grille.
- Don't push the bristles hard into the openings.
- Don't use liquids, compressed air or pins.
Step 4: Rule out software and settings
Sometimes "muffled" sound isn't water at all. - Remove the case and any screen protector that covers the earpiece. - Disconnect Bluetooth headphones or speakers that may be taking the audio. - Check volume and Silent mode, and test with a ringtone in Settings, then Sounds & Haptics. - Restart the iPhone. - Test both speakers: play music with the phone flat (both speakers) and make a call without speakerphone (earpiece only).
Diagnosis table
| Symptom | Likely cause | What to try |
|---|---|---|
| Muffled right after water | Water in the grille | Air dry speaker down; low tone |
| Gradually quieter over months | Lint or dirt build-up | Soft, dry brush |
| Crackling at high volume | Water, or speaker damage | Dry first; service if it persists |
| No sound from one speaker | Debris, damage or a setting | Brush, restart, test calls and media |
| Callers can't hear you | Microphone blocked or wet | Dry and clean the bottom mic openings |
Step 5: Still bad after a day?
Contact Apple Support or an authorized service provider. If water got inside, components may need inspection. Liquid damage isn't covered by Apple's standard warranty, but AppleCare+ covers accidental damage for a service fee. See does AppleCare+ cover water damage? for costs.
What not to do
- Don't use a hair dryer or other heat.
- Don't use compressed air, which can push water deeper.
- Don't put your phone in rice. Apple advises against it. See why you shouldn't put your phone in rice.
- Don't poke the grille with pins, needles or toothpicks.
Microphone muffled too?
iPhones have several microphones, including openings at the bottom near the speaker. If callers say you sound muffled, the mic openings may be wet or blocked. The same drying and gentle brushing apply. Record a short voice memo to test.
Preventing it next time
Keep your iPhone away from showers, pools and steam rooms, which Apple advises against. A waterproof pouch helps at the beach. And since water resistance decreases over time, an older iPhone is more likely to have water reach the speaker. See is my iPhone waterproof?
How to test the speakers properly
Play a song you know well at medium volume with the phone lying flat, then hold the bottom of the phone close to your ear to hear the main speaker alone. For the earpiece, make a test call or play a voicemail without speakerphone. Comparing before and after drying makes it easier to tell whether the sound has really improved.
Frequently asked questions
How long does it take for water to leave an iPhone speaker?
Often a few hours, sometimes up to a day. Place the phone speaker side down on a lint-free cloth in a dry spot with airflow.
How do I get water out of my iPhone speaker fast?
Point the speaker down, play a low-frequency tone at moderate volume in short bursts, and then let it air dry. Don't use heat or compressed air.
Why does my iPhone speaker sound muffled when it isn't wet?
Lint and dirt in the grille are common causes. Brush gently with a soft, dry brush, remove the case, and check Bluetooth and volume settings.
When should I take my iPhone in for a muffled speaker?
If the sound is still muffled or crackly a day after drying and cleaning, contact Apple Support or an authorized service provider.
