Your iPhone uses nine minutes as the snooze time for all your alarms. While there's no direct way to change this snooze duration, you can use a few workarounds to get alerts at custom intervals. Here's how.

There's no way to change the snooze time in Clock , but you can use a few workarounds.
The first method is to set multiple alarms on your iPhone. Each alarm after the main one is basically the snooze interval. For example, if you set the main alarm for 9 a.m. and want a five‑minute snooze reminder, create another alarm for 9:05 a.m. and another for 9:10 a.m., and so on.
To set multiple alarms and have each alarm act as a snooze reminder, open the app on your iPhone.
In the Clock app, at the bottom, tap “Alarm Clock.”
In the upper right corner of the “ Alarm ” page, tap the “ + ” (plus) symbol to add a new alarm.
You will see an “Add Alarm” screen. Here, specify the time for the snooze alarm. If your main alarm is set for 9 AM and you want a five-minute snooze reminder, set this alarm for 9:05 AM. Turn off the “Snooze” option as you won’t need it.
Then, choose other options, such as the sound for your alarm, the label, and so on. Finally, save your alarm by tapping “Save” in the top right corner.
