How to set an alarm clock on Xiaomi Redmi 9: 3 ways + problem solving

Why Redmi 9’s alarm clock might not work (and how to avoid it)

Xiaomi Redmi 9 is one of the most popular budget phones, but even its owners sometimes face the fact that the alarm does not work at the appointed time. The reasons can be different from a banal error in settings to system bugs MIUI. In this article, we will not only show how to set the alarm clock, but also analyze typical problems - for example, why the phone does not wake the owner in Do not disturb or with a discharged battery.

It is important to understand that on Redmi 9 (as well as on other Xiaomi smartphones), the alarm clock works through the standard “Clock” app, but it can be duplicated through Google Clock or third-party programs like Alarmy, MIUI-The alarm is integrated with system sounds, and Google Clock syncs with your account and works even after you reset your phone.

If you've never set an alarm on Android before, don't worry: it takes less than a minute. And for those who have tried it before but have problems (for example, the alarm goes off but the sound is too quiet or the phone doesn't wake up), we've prepared a separate solution section, and you'll also learn how to make the alarm work even when the phone is off, thanks to the MIUI Awakening feature.

Method 1: Standard Appendix "Clock" (MIUI)

The easiest and most reliable way to do this is to use Xiaomi's built-in Watch app, which is pre-installed on all Redmi smartphones and doesn't require any additional download, and it's intuitive, but there are a few things that many people don't know about, like setting up a smooth alarm clock volume increase or selecting a tune from your phone's music library.

To set the alarm:

1. Open the Watch app (an icon with a dial on the home screen or in the app menu).
2. Go to the Alarming Signal tab (bell icon at the bottom of the screen).
3. Press the + (plus) button in the lower right corner.
4. Set the time with the dial or enter it manually.
5. Set up additional parameters: 🔄 Repeat: Select the days of the week (for example, weekdays only). 🔔 Sound: tap on the current tune to change it. 📳 Vibration: turn on or off. 🕒 Delay: Set the space for the Delay button (5, 10 or 15 minutes). 📝 Title: Add a label (e.g., "Work" or "Charging").

Click Save (check in the upper right corner).

Now, the alarm clock will go off at the specified time. Note that if you've chosen a repeat by the days of the week, the alarm clock menu will be shortened next to the time (e.g., Pn-Pt). To edit or delete the alarm clock, press it long and select the desired item.

Make sure the time is set to 24-hour (if necessary) | Check that the alarm is on (the slider on the right should be green) | Set the signal volume to maximum in the sound settings | Turn off Do Not Disturb mode during the alarm clock

Method 2: Google Clock – sync with your account

If you use Google services, Google Clock can be more convenient than the standard one, and its main advantage is synchronization with your account: alarm clocks are stored in the cloud and automatically restored when you change your phone or reset your settings, and there is also a Smart Alarm that adjusts wake-up times to sleep phases (if you have a Mi Band fitness bracelet).

To set an alarm through Google Clock:

1. Download the app from Google Play (unless it is installed by default).
2. Open Google Clock and go to the Alarm tab.
3. Slip on + in the lower right corner.
4. Set the time and set the parameters: 🔄 Repeat: Select days or click Set up for a customized schedule. 🔔 The alarm clock sounds: there are more options than in the MIUI, including the sounds of nature. 🛌 Smart alarm: activate if you want to wake up in the optimal sleep phase (requires Mi Band or other tracker). 📊 Sleep statistics: Turn on to track how fast you wake up.

Press Save.

One of the key differences with Google Clock is that it allows you to set up a smooth wake-up (the sound starts to play quietly and gradually increase), which is useful if you are sensitive to sleep, and there is a feature called Weekend Mode that automatically turns off the alarm clock for Saturday and Sunday.

Method 3: Third-party apps (Alarmy, Sleep as Android)

If you don't like the built-in alarm clocks, you can install a third-party app.

• 🏆 Alarmy – Alarmy alarm clock with tasks (to turn off the signal, you need to perform a task, for example, scan). QR-code in the bathroom or do 10 squats).
• 😴 Sleep as Android – Analyzes sleep phases and wakes you up at optimal times.
• 🎵 Timely – beautiful design and cloud synchronization.
• 🔊 Loud Alarm Clock – the loudest signal (useful for fast sleepers).

Let’s look at the example of Alarmy:

1. Download the app from Google Play and open it.
2. Press + at the bottom of the screen.
3. Set a time and select the disable method (e.g., Mathematical Problem or Barcode Scan).
4. Set up additional parameters: 🔊 Loudness: You can set to maximum (even if the system sound is quiet). 🔄 Repeat: Flexible settings for each day. 📱 Vibration: It works harder here than in a standard alarm clock. 🚨 Emergency alarm: if you do not turn off the signal in 5 minutes, it will start ringing again.

Save the alarm.

Third-party alarms often consume more battery but offer unique features. For example, Sleep as Android can set up sleep monitoring using a microphone or accelerometer of the phone (without a fitness bracelet), and Alarmy ensures that you do not oversleep, even if the phone is silent.

💡

If the alarm doesn’t work in a third-party app, check the permissions: go to Settings → Apps → Permissions → Autostart and turn on the alarm clock autostart.

As you can see from the table, the best choice depends on your needs:

• If you need a simple and reliable alarm clock, you will need a standard MIUI.
• If syncing between devices is important, choose Google Clock.
• If you are sleeping well or want to track sleep, install a third-party app.
