Your alarm is probably quiet because of a mix of settings (volume, mode, or app‑specific options) rather than a broken device.

Common reasons it’s so quiet

  • Low alarm‑specific volume : Many phones have separate sliders for “media,” “ringer,” and alarm ; you might have cranked the ringer but left the alarm slider low.
  • Wrong or “None” sound : On some iPhones and apps, the alarm sound can be set to “None” or a very soft tone by accident.
  • Focus / Do Not Disturb / Sleep mode : These modes can silently lower or partially mute alarms depending on how they’re configured.
  • Attention‑Aware / Face‑ID features (iPhone) : On newer iPhones, “Attention Aware” can drop the volume if it thinks you’re looking at the screen.
  • Third‑party alarm apps : Some apps have their own internal volume sliders that override the system level.

Quick fixes by platform

iPhone

  1. Open Settings → Sounds & Haptics and raise the Ringtone and Alerts slider.
  1. Turn on “Change with Buttons” so the side buttons control alert volume (including alarms).
  1. In the Clock → Alarm tab, tap your alarm and confirm the Sound is not set to “None” and pick a louder tone.
  1. Go to Settings → Face ID & Passcode → Attention Aware Features and turn it off if you want max volume.

Android

  1. Press the volume buttons , then open the full panel and drag the Alarm slider (bell icon) all the way up.
  1. In Settings → Sound / Notifications , check that “Alarm volume” is high and that no “Do Not Disturb”‑style mode is muting alarms.
  1. If you use a third‑party alarm app, open its settings and look for an alarm volume or loudness slider.

If it’s still too quiet

  • Test the alarm sound outside of the Clock app (for example, by previewing it while editing) to confirm the tone itself isn’t inherently soft.
  • Restart the phone and re‑set the alarm; sometimes a software glitch quietly lowers the level.
  • If nothing works, the speaker or hardware may be damaged, especially if other sounds are also faint.
