Speaker Volume Too Low? Causes and Fixes

Quiet and clear, or quiet and muffled?

These are different problems.

• Quiet but clear. Everything sounds normal, just lower than it used to. This points to a setting or a limit.
• Quiet and muffled. Speech sounds as if it is coming through a cloth, and the treble has gone. This points to something physically blocking the grille.

Decide which describes your phone, then start in the matching section below.

Settings that lower the volume

• The wrong slider. Media, calls, ringer and alarms each have their own volume. Raise the volume while the sound you care about is actually playing.
• A volume limit. Phones include hearing-protection features that cap headphone loudness, and some also apply a media volume limit to the speaker. Look in sound settings for a volume limit or headphone safety option.
• Do Not Disturb or Focus. These lower or mute alerts without changing the sliders.
• Equaliser presets. A preset that cuts frequencies makes the whole phone sound quieter. Set it to off or flat.
• Per-app volume. Video and music apps have their own volume sliders inside the player.
• Bluetooth absolute volume. After using a Bluetooth device, the phone may remember a low level for it. Disconnect and check the phone’s own slider.

Restart the phone after changing these. If the volume returns for a while and then drops, an app is changing it, and testing in safe mode on Android will show which.

Things that block the sound

• The case. A badly aligned case can cover half the grille. Test without it.
• A screen protector over the earpiece. This is common after fitting a new one.
• Dirt on the mesh. Lint and skin oil build up over months. Brush the grille dry with the speaker facing down, as described in cleaning phone speakers without damage.
• Water. If the phone was recently wet, run the water eject tool with the speaker pointed down.

Measure it instead of guessing

Open the tone generator, choose 1 kHz and set its volume slider to about half. Raise the phone’s volume to maximum and listen.

• A 1 kHz tone at full phone volume should be uncomfortably loud at arm’s length. If it is, the speaker is fine and the quietness comes from the app or the recording.
• If 1 kHz is loud but 4 kHz and 8 kHz are faint, the mesh is partly blocked.
• If every tone is weak, and settings are ruled out, the speaker is worn or damaged.

Why volume booster apps are a bad idea

Booster apps cannot make the speaker’s amplifier more powerful. They raise the signal level until the peaks are clipped off, which sounds louder at first because it adds distortion. Clipped audio heats the voice coil far more than clean audio does, and small speakers fail that way. If you need more volume than the phone can give cleanly, an external speaker is the answer.

When the speaker is wearing out

Speakers lose output with age, particularly if they have been played at maximum for long periods or exposed to water repeatedly. If your phone is several years old, is clean, has no limits set and is still quiet in the tone test, a replacement speaker module will restore it. It is usually an inexpensive repair.
