If your Realme 16 alarm did not ring this morning, that can ruin your entire schedule. You may have set it correctly, but something prevented it from sounding at the right time. The issue is usually caused by silent settings, battery restrictions, or incorrect alarm configuration, and you can fix it in just a few minutes.
Why Your Realme 16 Alarm Is Not Going Off
- The alarm volume is set too low or muted.
- The phone was powered off before the alarm time.
- Battery optimization is restricting the Clock app.
- Do Not Disturb mode is interfering with alarm sounds.
- The alarm was set for the wrong day or time.
Check the Alarm Volume
Alarms use the dedicated alarm volume, not media volume. If this is muted or set too low, the alarm may vibrate only or stay silent.
Open Settings, and then tap Sound and vibration.
Tap Volume, and then increase the Alarm volume slider.
Lock your phone and test a new alarm for a minute ahead.
Make Sure the Alarm Is Enabled Correctly
Sometimes the alarm is created but not turned on. It may also be scheduled for a different day without you noticing.
Open the Clock app, and then tap Alarm.
Select your alarm, and then make sure the toggle switch is turned on.
Check the time, repeat days, and AM or PM setting.
Disable Battery Optimization for Clock
Battery optimization can prevent background apps from working properly. If the Clock app is restricted, it may not trigger the alarm on time.
Open Settings, and then tap Battery.
Tap App battery management, and then find Clock.
Set it to Allow background activity or No restrictions.
Turn Off Do Not Disturb Temporarily
While alarms usually override Do Not Disturb, custom settings can block sound if misconfigured. It is worth checking to rule it out.
Open Settings, and then tap Notifications and status bar.
Tap Do Not Disturb, and then turn it off temporarily.
Set a test alarm to confirm it works.
Restart Your Realme 16
A quick restart refreshes system processes and clears temporary bugs. It often fixes minor alarm glitches without changing any settings.
Press and hold the Power button, and then tap Restart.
Wait for the device to power back on, and then test the alarm again.
Your Realme 16 alarm should work reliably once volume levels are correct and battery restrictions are removed. After adjusting these settings, set a short test alarm to make sure everything works before you rely on it overnight.
