iPhone 16 Plus Speaker Not Working?
Speaker problems on the iPhone 16 Plus typically manifest as no sound, very low volume, or distorted audio. Before assuming hardware failure, check that the phone isn't in silent mode, that volume is turned up, and that the speaker grille isn't clogged with lint — a surprising number of "dead speaker" cases are resolved with a simple grille cleaning.
Common Symptoms
Common Causes
- 1Speaker grille blocked with lint, dirt, or debris — very common in the bottom grille of the iPhone 16 Plus
- 2Speaker damaged by liquid ingress
- 3Blown speaker from audio played at maximum volume for extended periods
- 4Loose or disconnected speaker flex cable
- 5Logic board audio IC fault (less common — affects both speakers)
- 6Earpiece speaker separate from bottom speaker — each can fail independently
How to Fix It
- Check silent mode switch (left side of phone) and volume buttons first
- Clean the speaker grille gently with a dry toothbrush — this is free at iTech Repairs
- Go to Settings → Accessibility → Audio/Visual and check Balance slider is centred
- Test with a speaker test app to confirm which speaker is affected
- Speaker replacement — bottom speaker or earpiece, same-day service
- Audio IC diagnostics if both speakers are affected simultaneously
