How can I tell if water damaged my microphone rather than my speaker?
If people on calls say they cannot hear you clearly but you can hear them fine, the microphone is more likely affected than the speaker. You can also record a voice memo and play it back. If the playback sounds muffled or distorted even through headphones, the microphone is the source of the audio problem rather than the speaker. If the playback sounds fine but the speaker sounds muffled, the speaker is the issue.
Can the speaker eject tool help with microphone water damage?
The eject tone plays through the speaker, which helps the speaker specifically. The microphone is a separate component with its own opening, usually at the bottom of the phone near the charging port. Pointing the microphone opening face-down on a dry cloth and allowing passive drying is more effective for the microphone than playing an eject tone. You can do both simultaneously by orienting the phone so both the speaker grille and microphone port face down.
How long does a water-damaged microphone take to recover?
Microphone recovery typically follows a similar timeline to speaker recovery. Most mild moisture cases clear within 30 to 60 minutes of passive drying with the microphone port facing down. More significant exposure may take one to two hours. Record a voice memo test every 20 to 30 minutes to track improvement. If the microphone remains muffled after two hours of drying, corrosion or physical damage to the MEMS microphone element may have occurred.
