To change the sound for a regular iPhone alarm, open the Clock app, go to Alarms, select the alarm you want to edit, then tap Sound. Choose a ringtone, song, or available alert option and save the alarm.
Choose a different alarm sound
- Open the Clock app.
- Tap Alarms.
- Tap the alarm time you want to change. On some iOS versions, tap Edit first.
- Select Sound.
- Choose the sound you want.
- Return to the alarm settings and tap Done.
The iPhone 6S interface depends on its iOS version
The iPhone 6S is an older model and cannot run the newest iOS releases, so its Clock screens may look different from Apple’s current screenshots. The basic idea remains the same: edit the alarm itself and change its Sound setting.
If the alarm is too quiet
Alarm volume is controlled by the Ringtone and Alerts volume under Settings > Sounds & Haptics on supported iOS versions. Silent mode and a normal Focus do not prevent a regular Clock alarm from sounding.
Sleep schedule alarms are different
If the alarm comes from an Apple sleep schedule rather than a regular Clock alarm, edit the wake-up alarm associated with the sleep schedule. That workflow can differ from editing a standard alarm in Clock.
