For a growing number of iPhone owners, the most basic promise of a smartphone, waking you up on time, has become unreliable. Reports of alarms firing silently or at barely audible volume have piled up across support forums, social media and broadcast TV, turning a routine feature into a genuine risk for shift workers, travelers and anyone with a tight schedule. I want to walk through what is actually going wrong, what Apple has acknowledged, and the concrete steps you can take right now to avoid getting caught by the same glitch.
At the heart of the problem is a mix of software quirks and confusing settings that make it far too easy for a perfectly configured alarm to whisper instead of shout. Some users say the issue has persisted across multiple iOS versions, including people who report still seeing problems on iOS 17.6. The good news is that there are now several well tested workarounds, from simple settings tweaks to backup alarm strategies, that dramatically cut your chances of waking up to a silent screen.
Why iPhone alarms are failing in the first place
The current wave of alarm complaints did not start in a vacuum. Concerns were pushed into the spotlight by early risers on NBC’s NBC Today Show, where viewers described alarms that appeared correctly set but did not make a sound. In a separate report, Tuesday coverage noted that Apple told the Today Show it was aware of a glitch that was causing alarms to not make noise for many users. That acknowledgement matters, because it confirms this is not just user error or a handful of isolated devices.
At the same time, long running threads on Apple’s own forums and on Reddit suggest there is more than one failure mode. One Apple Support Communities user described how their iPhone alarms were usually silent and did not vibrate on an iPhone 12 Pro Max, with support staff noting that There could be several reasons why alarms fail. On Reddit, one poster bluntly wrote that they initially blamed anxiety and exhaustion for oversleeping before deciding it was Just Apple being Apple. Another user in a separate thread said they would not be surprised if the bug had even claimed lives, and that they were still facing the alarm bug issue on iOS Jul.
First line of defense: fix the obvious settings
Before assuming you are dealing with an unfixable software bug, I would start with the basic checks that repeatedly show up in successful troubleshooting stories. One long running Apple Support Communities post describes how a user named grahamfromweston solved their problem by going into Settings, opening Sounds, and adjusting the Ringer and alerts slider so it was not left low from the night before. A detailed troubleshooting guide recommends doing similar due diligence, advising users to open Settings, review their alarm configurations and confirm that the correct sound is selected before following the Doing steps laid out there.
Volume controls are another recurring culprit. Several walkthroughs point out that if you head into the Settings app, scroll to Sound & Haptics and adjust the volume there, you can decouple alarm loudness from the physical buttons. One guide suggests that after you tweak the slider, you should back out and head over to the Settings app again, then scroll down until you reach Sound and Haptics, or search for it directly, mirroring the advice in a popular Dec tutorial. Another video focused on alarms that are completely silent walks through a similar process, promising to show exactly how to fix the issue in the next two minutes and positioning that as the first step in an Nov walkthrough.
The hidden role of Attention Aware and other smart features
Once the basics are in order, the next suspect is a set of “smart” features that quietly change how loud your phone is when it thinks you are paying attention. On iPhone X and later, a setting called Attention Aware Features uses the TrueDepth camera to detect whether you are looking at the screen. According to Apple’s own description, when your phone detects that you are looking at your screen it will not dim the display and will lower the volume of your alerts, a behavior that some users say is interfering with alarms, as explained in a detailed When explainer. A separate troubleshooting guide goes as far as calling this setting the most common cause when an iPhone alarm is not going off at all, framing it as the primary Fast fix.
Users themselves have started to converge on the same diagnosis. In a widely shared Reddit post, one person laid out a checklist that put this setting at the top, writing that the Most important step was to check if “Attention Aware” was enabled and to make sure it was not if alarms were acting up. A separate how to guide that walks through six specific fixes for the silent alarm glitch also highlights this, listing “Disable ‘Attention Awa” as one of the core steps in its Table of Contents. That same guide opens with a section labeled How to fix the silent alarm glitch and moves quickly into Immediate settings to check first, underlining how central this feature has become to the conversation.
Locking down volume so alarms stay loud
Even if Attention Aware is off, there is another subtle way alarms can be sabotaged, by accidental volume changes. Several guides now recommend turning off a setting called “Change with Buttons” so that the physical volume keys no longer affect alarm loudness. One detailed walkthrough notes that You might also want to turn off Change with Buttons to make sure you are not adjusting the alert volume accidentally, and stresses that Alarms should then be more consistent. That advice lines up with the experience of users who discovered their ringer volume had been nudged down while watching videos or playing games, only to find their morning alarm whispering at the same level.
Creators who have documented their own alarm failures have landed on similar fixes. One viral clip described a simple hack that stopped the silent alarm problem for that user, with the poster explaining that it had been happening so much on their iPhone that they now tell people to maybe do not trust your Dec alarm. In that same discussion, She warned that the volume might accidentally change, especially when the phone is handled in bed, and suggested that relying entirely on Apple’s default behavior was no longer wise.
Backup plans: alternative apps and old school clocks
Given the stakes, I would not stop at a single line of defense. Some guides now explicitly recommend using third party alarm apps as a backup, or even returning to a dedicated bedside clock. One analysis of the bug notes that alternative alarm apps can provide redundancy and that something else you can do is to keep a cheap digital clock with big red numbers and real buttons next to the bed, advice that appears in a detailed Here breakdown. That same piece frames the issue by asking What exactly the silent alarm bug is, then moves quickly into practical mitigations.
Others have gone further, building multi step routines that combine iPhone alarms, third party apps and physical devices. A comprehensive how to guide that walks through six fixes ends with a nuclear option, suggesting that if all else fails, you may need to reset your iPhone after working through the earlier steps in its Dec guide. Another troubleshooting piece focused on alarms that go off silently emphasizes doing due diligence Before you assume the worst, but still implicitly endorses the idea of layered protection by encouraging users to test alarms repeatedly after each change.
