Water and speaker care

iPhone speaker sound check after a splash

A quick channel and volume check can tell you whether muffled sound is improving after moisture is removed.

A clear sequence

Start with the device at a comfortable volume.
Play a voice or tone that makes left and right balance easy to hear.
Listen for rattling, crackle, or one channel that is quieter.
Repeat the check after a short drying interval and record what changed.
Stop if the phone becomes hot or a system warning appears.

Keep the test short and consistent so you are comparing the speaker, not changing several variables at once.
