Alarm won't go off on my iPhone XR with IOS 17.2.1

A schedule has been set for 10 pm until 6 am. The alarm won’t ring in the morning. If I set it to ring after I am awake, it works. The same thing happens when the alarm is set to a different time; it doesn’t ring. But if I set it to a later time, after I’m awake, it works. There is no sleep focus set, nor is “Do not disturb” turned on. This is on an iPhone XR with IOS 17.2.1

Interessting…

I‘ve updated my iPhone SE 2020 yesterday on IOS 17.2.1 and just a little bit before midnight I set my alarms (I usually set 3-4 alarms just be sure).

Today I woke up a hour later as the first alarm would have rang. I immediately opened the clock app and recognized that all of a sudden all alarms are deactivated.

I never had this issue so I wonder what will happen tomorrow…

Let us assume the sleep schedule that you have set for each day: Assume today is Friday, January 4th, 2024

  • Monday and Saturday: Sleep 21:00 to Wake 07:00
  • Tuesday, Wednesday, and Thursday: Sleep 22:00 to Wake 06:00
  • Friday and Sunday: Sleep 23:55 to Wake 06:00


Check this are you getting these alarms as shown below?


Let's plot the scheduled sleep and wakeup times for the days surrounding today (Friday, January 4th, 2024):

  • Friday (Today): Sleep 23:55 to Wake Friday Morning: 06:00 (for the night of January 4th)
  • Saturday: Sleep 21:00 to Wake up Saturday Morning at 07:00
  • Sunday: Sleep 23:55 to Wake up Sunday Morning at 06:00
  • Monday: Sleep 21:00 to Wake up Monday Morning at 07:00



To summarise

Morning Wake up alarm would look like this

  • Sunday: 6 AM
  • Monday: 7 AM
  • Tuesday: 6 AM
  • Wednesday: 6 AM
  • Thursday: 6 AM
  • Friday: 6 AM
  • Saturday: 7 AM

A schedule has been set for 10 pm until 6 am daily. The alarm won’t ring in the morning. If I set it to ring at a later time, after I am awake, it works. The same thing happens when the alarm is set to a different time; say 7 am or 6:30 am; it doesn’t ring. But if I set it to a later time, after I’m awake, it works. There is no sleep focus set, nor is “Do not disturb” turned on. This is on an iPhone XR with IOS 17.2.1
