Change Snooze Length auf Android
The gap between one alarm ring and the next snooze is not fixed on Android. It comes from a single setting inside the Clock app that controls how many minutes pass before the alarm sounds again after you tap snooze.
If that gap is too short, you barely get back to sleep before the phone rings again. If it is too long, you risk drifting off and missing the alarm entirely. Changing the value fixes both problems without touching the alarm time itself.
Where to find the setting
Open the path below inside the Clock app: Tap on Clock ➔ Open the menu ➔ Open the settings ➔ Tap on Snooze lenght ➔ Choose an option.
Pick the interval that fits how you actually wake up. A shorter interval suits light sleepers who wake easily, a longer one suits anyone who needs more time between repeats.
This setting applies to every alarm you set afterward, not just one. If you want a different snooze behavior for a single alarm only, you would need a third-party alarm app, since the built-in Clock app applies this value globally.
