To increase your alarm volume on an iPhone 15, you will change the ringer and alerts volume in Settings, enable the option to let the side buttons change that volume, pick a louder alarm sound in the Clock app, and check a few system settings that can reroute or limit sound. Follow the quick steps below and test with a sample alarm. If the volume still seems low, make sure your iPhone is not connected to Bluetooth speakers, restart the phone, and update iOS.
Tutorial – How To Turn Up Alarm Volume On iPhone 15
This section shows the exact steps to raise your alarm volume and make alarms louder and more reliable.
Step 1: Open Settings and tap Sounds & Haptics.
Go to the Settings app, then tap Sounds & Haptics to find the Ringer and Alerts slider.
In Sounds & Haptics you will see a slider labeled Ringer and Alerts. Move that slider to the right to increase the system volume, which also controls alarm loudness. This slider is the main control for alarm volume.
Step 2: Turn on Change with Buttons if you want to use the side buttons.
Toggle on Change with Buttons to let the side volume buttons adjust Ringer and Alerts volume.
When Change with Buttons is on, pressing the volume up or down buttons will change the ringer and alarm volume directly. If it is off, the side buttons will only change media volume like music or video.
Step 3: Press the side volume up button to raise alarm volume.
Use the physical volume up button on the left side of the iPhone to increase the ringer and alarm volume when Change with Buttons is enabled.
Press once or hold the button to move the volume higher. You will see the Ringer indicator on screen if Change with Buttons is active. Keep an eye on the on-screen feedback to reach the level you want.
Step 4: Open the Clock app and choose a louder alarm sound.
In the Clock app, edit your alarm, tap Sound, and select a louder tone or a song to make the alarm more noticeable.
Some tones are very soft while others are sharp and loud. Pick a sound with a strong, rising pattern so it wakes you reliably. You can also add vibration to the alarm for extra notice.
Step 5: Make sure you are not connected to Bluetooth audio.
Check Control Center to see if your iPhone is sending sound to Bluetooth headphones or a speaker and disconnect if needed.
If your phone is paired to AirPods or a Bluetooth speaker, the alarm may play through that device instead of the iPhone speaker. Disconnecting or turning Bluetooth off sends alarm audio back to the phone’s speaker.
Step 6: Disable Attention Aware Features if volume drops when you look at the phone.
Open Settings, Face ID & Passcode, then turn off Attention Aware Features to stop the phone from lowering sounds while you are looking at the screen.
Attention Aware can reduce alert volume when the phone thinks you are paying attention. Disabling it prevents the system from softening alarms because it senses your face.
Step 7: Restart or update iOS if alarm volume is stuck.
If volume controls do not respond, restart your iPhone or check Settings > General > Software Update to install the latest iOS fix.
A restart can clear temporary glitches. Updates sometimes fix sound bugs that prevent alarms from playing at full volume.
After you complete these actions your alarm should sound at a higher, more reliable volume from the iPhone speaker. Test by setting a short test alarm to confirm the change. If it still seems too quiet, try a very loud tone and ensure Bluetooth devices are disconnected.
Tips for How To Turn Up Alarm Volume On iPhone 15
- Test alarms immediately after changing settings so you know the new volume level.
- Choose alarm tones with a rising volume or strong beats for better waking power.
- Set multiple alarms a few minutes apart to avoid sleeping through one quiet alarm.
- Use Emergency Bypass for important alarm contacts so their alerts come through regardless of focus modes.
- Keep your iPhone speaker clean and free of debris for the loudest possible sound.
- Consider turning off Bluetooth before bed if you often forget to disconnect devices.
- Use a vibration plus sound combination to add a physical cue that can help wake you.
Frequently Asked Questions
Why is my iPhone 15 alarm so quiet even when volume is high?
A quiet alarm often means the Ringer and Alerts slider is low, or your phone is sending audio to a Bluetooth device. Check Settings > Sounds & Haptics and Control Center to confirm the Ringer slider and disconnect Bluetooth devices.
Will alarms ring when my iPhone is on silent mode?
Yes, iPhone alarms will still ring even if the ring/silent switch is set to silent. Alarms use system alerts so they bypass the silent switch. You still need the Ringer and Alerts volume turned up.
Can I make the alarm volume different from ringtone volume?
No, alarm volume and ringtone volume are tied to the same Ringer and Alerts slider. To change alarm loudness adjust that single slider or pick a louder tone for the alarm.
Does Do Not Disturb or Focus mode stop alarms?
No, standard alarms created in the Clock app will still sound during Do Not Disturb or Focus modes. However, custom alarm apps or third-party apps might be affected by focus settings.
My volume buttons are not changing alarm volume, what do I do?
If Change with Buttons is off in Settings > Sounds & Haptics, the side buttons will only adjust media volume. Turn Change with Buttons on to let the side buttons change the ringer and alarm volume.
Could a software bug make alarms quieter on iPhone 15?
Yes, software glitches can affect volume behavior. Restart your iPhone and install any iOS updates to fix bugs. If problems persist, contact Apple Support.

Conclusion
Getting your alarms loud enough to actually wake you is a small effort that pays off every morning. The iPhone 15 uses the Ringer and Alerts volume for alarms, so the most direct solution is to raise that slider in Settings, or enable Change with Buttons to use the physical volume keys. Picking a strong alarm tone, disconnecting Bluetooth devices, and avoiding features that lower sound like Attention Aware will make sure your alarm sounds as intended. If something still feels off, a quick restart or software update often clears strange bugs.
Think of your alarm like a smoke detector. You want it loud and clear so you do not miss it. A quieter alarm might be caused by a setting, a paired device, or a buggy update. By following the steps in this article you will know how to turn up alarm volume on iPhone 15 and reduce the chance of sleeping through it. Try a test alarm now and adjust the tone and volume until it matches how loud you need it to be. If you need more help, Apple Support and Apple Store technicians can run diagnostics on the speaker and software to make sure everything is working correctly.
