Steps to solve the iPhone alarm not going off
Step 1: Download and install TunesKit iOS System Recovery. Launch it and hook up your iPhone with the computer. When the program detects your iPhone, click on the "Enter Recovery Mode" button and your iPhone will be ushered into the recovery mode. After that, hit the "Start" button to continue.
Step 2: In this window, there are two repairing modes on the screen. Tap the "Standard Mode" button so that your iPhone alarm will be fixed without data loss. Then click on the "Next" button.
Step 3: Ensure the model information of your iPhone shown on the screen is correct. Next, press the "Download" button to let the software download the firmware package matching with your iPhone.
Step 4: After the firmware package is downloaded, press the "Repair" button to initiate the repairing process. When this process is completed, the phone will reboot and your alarm should sound normally.
Fix 2: Adjust the Ringtone Volume Settings
To many people, the first reaction upon finding out their alarms not working is to maximize the volume by holding the "Volume Up" button. However, this action may not actually increase the alarm volume, as holding the "Volume Up" button will increase the volume of the app you are currently using.
To make sure your alarm volume is maximized, follow the steps below. Go to "Settings" > "Sounds" (or "Settings" > "Sounds & Haptics"), and make sure "RINGER AND ALERTS" is set to a reasonable volume. Also here you should switch off the "Change with Buttons" option to make sure the ringer and alarm volume never change when you change the system volume with the buttons.
Fix 3: Turn Off the Do Not Disturb Option
Since the Do Not Disturb feature mutes all calls, alerts, and notifications on your iPhone, you should switch off this feature when the iPhone alarm does not go off. To turn it off, go to "Settings" > "Do Not Disturb" and switch off the feature. Or you can go to the control center and tap on the crescent-shaped icon to turn off the feature.
Fix 4: Disable Bluetooth and Disconnect All External Playback Device
As a lot of people have the habit of linking their iPhones to Bluetooth headphones or other external playback devices, they are likely the culprits. When you have your iPhone connected with those devices and they are muted, there is no wonder that you won’t hear the alarm sound because it is played through the muted external devices instead of the phone speaker.
Therefore, the ideal solution is to turn off the Bluetooth in the Settings and disconnect all the external playback devices that are physically connected with your phone.
Fix 5: Set Multiple Alarms
One alarm might not work occasionally, what about 2 or even more? The point of setting an alarm is to inform you of the time to do something, so you might as well set multiple alarms around the same time to make sure at least one of them will sound. Even when you have fixed the alarm with the previous solutions, we still suggest you keep multiple alarms to avoid the resurgence of the problem. Besides, you can delete the alarm previously set on your phone by swiping right it in the Alarm app, then create another one that alarms at the same time.
Fix 6: Consult Apple Support
If all the solutions above fail to work and you still find yourself waking up late without hearing the alarm, it’s time to resort to Apple Support. The technicians of Apple Support will fix your iPhone, especially when hardware issues strike.
Summary
The iPhone alarm not going off problem is indeed bothering and critical. Serious results will come when it is handled not properly. Luckily, with the solutions we list, you will either get rid of the issue or reduce its side effects.
