Clock app not working on my iPhone 14 after updating to iOS 18

ME TOO! I woke up an hour after my alarm and was late to work after updating. The notification was on my screen, but it never actually made a sound.

also to note, this has happened to me every time I update and then gets fixed a couple weeks after. It’s super weird and it cost me a hectic morning or two.

I bought myself an analog backup alarm from Amazon. At least that won’t turn on me. Geez.

I have found a workaround for this. Turn off standby mode. I was late to work 3 days in a row, and being a computer programmer, I broke down the whole system and figured out that if standby mode is enabled, then it can put the phone into a resting state that will disable cell phone sounds completely until your phone detects motion. Well being you are sleeping, you don’t move around much so after your phone sits idle for a designated amount of time, it will go completely quiet as to not disturb your sleep. Turn standby mode off completely and your phone will start working again. You may not get the cool standby screen when your phone is charging anymore, but it will fix this issue.

Me starting today, after updating iOS 18.3.1

I’ve spoke with a few people having this issue, it’s happened to me as well. Make sure that your volume buttons do not toggle the volume of your system. Only your media.

other than that, just get an alarm clock.

$1300 for a broken alarm clock ain’t worth the fuss. Besides, we all know Apple ain’t looking at this forum thinking we’re all exemplary citizens. They more than likely will shrug it off thinking we’re all lazy shmoozers.

My alarm does work but when I select skip the night before, it still wakes me at the regular time. The first time I thought I must not have made contact with it when selecting but it happened again this morning.

Ok. I'm going to turn StandBy mode off to see if the alarms will work tomorrow. My alarms have not worked for the past 2 mornings ever since I updated to iOS18. Will I have to leave StandBy mode off forever and ever?

I deleted the daily recurring wake up setting, then set it again. My wake up always worked but the “Skip” option had stopped until I removed the setting. Hope that works for you.

Same, it shows the widget clock on the lock screen as off but i have set alarms in the app, also it works only if i put another time but not when i need to wake up for school and it didn’t go off
