iPhone alarm glitch leaves thousands of furious users facing a surprise lie-in - as one vents 'I felt crazy trying to explain this to my boss'
There's nothing more panic-inducing than waking up and seeing you've somehow slept through all of your alarms.
But if missed alarms have made you late to work recently, it might not be your fault.
An iPhone glitch has caused alarms not to ring on time or to trigger silently, leaving thousands to face a surprise lie-in.
Apple said it was working on a fix for this issue as far back as April last year, but furious users say the feature still isn't working.
Despite last week's software update, which provided 'important bug fixes', the issue appears to be affecting even the latest versions of iOS.
Frustrated Apple fans have flocked to social media to vent their annoyance and share examples of their faulty alarms.
On Reddit, a user shared an image of an alarm set for 10:30 which ultimately triggered at 12:42 later that night.
One commenter wrote: 'Thank you! I felt crazy trying to explain this to my boss and not sound like I’m lying.'

Apple first acknowledged an issue with the alarm feature in the clock app last year when it revealed that engineers were working on the fix.
However, since then, users have continued to report significant issues with their alarms.
The glitch causes alarms that are set for a specific time to fail to trigger or only to activate several hours later.
'I over slept today for work and was p***** started driving to work as I got there late my alarms started going off,' one Reddit commenter wrote.
Another said that their alarms set for five in the morning only turned on at seven later that day.
However, many users also report that their alarms activate only as silent notifications on the home screen rather than ringing in any way that could wake them up.
On Reddit, a commenter wrote: 'My morning alarm was displaying as going off while making no sound and no haptics for 40 minute.'
Another added: 'I’ve had multiple days where I’ve been late because my alarm goes off… in silent mode. I look at my phone and the alarm screen is up, but the phone is silent.'

On X, iPhone users slammed Apple for failing to fix the issue which has been causing the alarm app to malfunction

One user joked that Apple was a 'trillion dollar company but can't make a functioning alarm app'
Additionally, users report that these issues occur on multiple iPhone models and software versions including the latest iOS 18.2 update.
In another post, one user said they upgraded from an iPhone 12 Pro Max to an iPhone 16 Pro Max in the hopes of fixing the problem.
However, the user found that their alarms were still ringing silently.
Meanwhile, on X, commenters slammed Apple for failing to fix this key issue with one user joking: 'Apple trillion dollar company but can't even make a functioning alarm app lol.'
Another commenter wrote: 'Apple needs to get its act together. My iPhone and Apple Watch alarm have failed to ring countless time.'
If you are experiencing problems with alarms not ringing, the first thing to check is whether your phone's volume is actually turned up.
Cranking up your iPhone's media volume, which makes music or videos louder, doesn't actually change the volume of alerts.
To do this, open Settings and tap on the tab marked 'Sound and Haptics'.

One possible solution is to turn off 'Attention Aware Features' which turns down the volume on some alerts when the phone recognises a user's face
From there, turn the 'RINGTONE AND ALERTS' slider up to full to ensure your phone will ring loudly.
It can also help to turn 'Change with Buttons' off since this makes it easy to accidentally mute your alarms throughout the day.
If that doesn't work, some users have reported success by disabling the 'Attention Aware Features' on the iPhone.
This option checks whether you are looking at your phone to do things like expand notifications on the home screen, but it also mutes alarms that go off while you're on your phone.
If you sleep with your phone on a stand or the bed near you, this might mute alarms before they have a chance to wake you up.
To turn this feature off, open Settings and navigate to 'Face ID & Passcodes' and toggle 'Attention Aware Features' off.
While this has worked for some users, not everyone says this has fixed the issue and deactivating the setting means missing out on some handy features.
Apple has been contacted for comment.
