2. Go to the tab "Alarm clock"** (the bell icon in the lower menu).
3. Press the + button in the lower right corner.
4. Set the trigger time by dragging the arrows or entering numbers manually.
5. Press "Done" - the alarm is saved.

The default signal will be a single time. To make it repeatable, tap the alarm clock and select the days of the week (for example, "Pn-Pt" for working days), and you can change the melody, vibration and volume.

Customization of melody, vibration and volume

The standard alarm clock tune on Redmi 9A may seem too quiet or annoying, and luckily, it's easy to change:

1. Open the tab "Alarm clock"** in the app "Clock".
2. Touch the alarm clock (do not press the switch!).
3. Slip on the item "Alarm clock sound"**.
4. Select one of the preset tunes or click "Add»** (+), To download your file (the file must be in the format.mp3 or.m4a).

To adjust the vibration:

• 🔔 In the same alarm clock editing menu, turn on the option “Vibration»**.
• 🎵 Choose the vibration type: short, long, or custom (if supported by your version) MIUI).
• 🔊 Adjust the volume of the alarm clock separately from the total volume of the phone – for this, use the “Alarm Slider”** in the sound settings (Settings) → Sound and vibration).

💡

If the alarm clock is too quiet, check to see if Quiet is on in the sound settings, and make sure the speaker is not covered with a cover or fingers while you sleep.

Repeated alarm clock and weekend exceptions

If you need to wake up at the same time on weekdays but sleep longer on weekends, set a repeating alarm clock with exceptions:

1. Set an alarm as described above.
2. Tap it for editing.
3. In the section "Repeat"** select days: for example, "Pn", "W", "Sr", "Cht", "Pt".
4. To cancel the alarm for a specific day (such as Saturday), simply uncheck the tick opposite the "Sb".

For convenience, you can create separate alarm clocks for different days:

• 🕖 Alarm 1: 7:00, repeat on weekdays.
• 🛌 Alarm 2: 9:00, repeat on Saturdays and Sundays.
• ⏰ Alarm 3:6:30, single to an important event.

Problem Solving: The alarm clock doesn’t work

If Redmi 9A doesn’t wake you up on time, there may be one of the following reasons for the problem:

Third-party apps for alarm clocks: when they are needed

The built-in Watch app is suitable for most tasks, but if you need advanced features, consider alternatives:

• 🔔 Google Clock – sync with Google account, smooth volume increase, tasks for the morning.
• 🌅 Sleep as Android – a smart alarm clock with sleep phase analysis (requires access to microphone and accelerometer).
• ⏳ Alarmy – An alarm clock with tasks (for example, scanning) QR-code in the bathroom to turn off the signal).
• 🎶 Musical Alarm Clock – Playing playlists from Spotify or YouTube Music.

To set a third-party alarm:

1. Download the app from Google Play Market.
2. Open it and provide the necessary permissions (access to microphone, notifications, etc.).
3. Set the alarm according to the instructions of the application.
4. Add it to the battery optimization exceptions (similar to the built-in app).

💡

If you use Sleep as Android, place your phone next to your pillow – the app analyzes sleep movements and selects the optimal time to wake up in the REM sleep phase.
