How to set an alarm clock on Xiaomi Redmi 9: 5 ways + error solving

The alarm clock on Xiaomi Redmi 9 is not just a wake-up function, but a whole tool for planning the day. Despite its apparent simplicity, many users face difficulties: the app does not open, the sound does not work, the alarm clock is reset after rebooting. In this article, we will discuss all possible ways to set the alarm clock, from the standard Watch app to alternative solutions, and also tell you how to avoid typical errors.

The Redmi 9 (codenamed lancelot) is a MIUI firmware that can vary by region and version. For example, the global firmware interface of the Watch app looks different than in Chinese. We took these nuances into account and prepared universal instructions that will be suitable for any modifications of the Redmi 9, Redmi 9A, Redmi 9C and Redmi 9T.

1. Standard Clock App: Basic setting

The most obvious way is to use Xiaomi’s built-in Watch app, which is pre-installed on all Redmi 9 series devices and doesn’t require additional downloads.

1. Open the app — find the Watch icon on the home screen or in the app menu, which usually looks like an analog watch with a white dial.
2. Go to the tab "Alarm clock" - it is located in the lower panel (bell icon).
3. Add a new alarm clock – press the + button in the lower right corner.
4. Set the time — scroll the wheels to select hours and minutes. Redmi 9 can set the time to the minute.
5. Select the days of repetition – tap the Repeat field and mark the desired days (for example, “Pn-Pt” for working days).
6. Select a tune – in the Sound section you can select a standard signal or download your audio file (.mp3,.wav formats).
7. Save the alarm clock - press Ready in the upper right corner.

Important: Redmi 9 with MIUI 12.5+ has a Smart Alarm feature that analyzes sleep phases and determines the optimal time to wake up. To activate it, go to the alarm settings and turn on the Adaptive Awakening option.

Check the correct time (AM/PM!)

Make sure the alarm is on (the slider is active)

Select the volume of the signal (at least 50%)

Turn off the "Do Not Disturb" mode for the duration of operation-->

On Redmi 9, the alarm may not work if the phone is completely discharged or in Ultra Battery Saver mode. To avoid this, make sure that the battery is at least 15% at bedtime, or connect the device to charge.

Alternative appendices for alarm clocks

If the standard Watch app does not suit you (for example, due to a poor selection of tunes or the lack of a gradual increase in volume), you can use third-party programs.-3 Verified options for Redmi 9:

• 🔔 Google Clock is the official Google app with minimalist design and integration with Google Assistant. Supports voice control and sleep modes.
• 🎵 Sleep as Android – a smart alarm clock with sleep analysis, wake-up captches and the ability to sync with wearable devices (for example, Mi Band).
• 🌅 Alarmy – application with hard methods of awakening: to turn off the alarm clock, you need to scan the barcode or solve a mathematical problem.

To install one of these applications:

1. Open the Play Store on your Redmi 9.

Third-party alarms have the advantage of enhanced features, like Sleep as Android, which allows you to set up a smart REM sleep wake-up to make the morning less painful, and Alarmy is for those who constantly turn off their alarm clocks while they sleep and wake up late.

3. Set up an alarm clock via Google Assistant

If you're too lazy to dig through the menu, you can set the alarm with your voice using Google Assistant, which works on Redmi 9 with Google services installed (they are the default in global firmware).

1. Activate the voice assistant – say OK, Google or hold the Home button (if it’s touch-sensitive).
2. Select the command – for example: Set the alarm for 7:30 for tomorrow Set the alarm for 6:00 each weekday Set the alarm for 8:00 with the label "Get to work"
3. Confirm the creation, the assistant will give you the time and days of repetition. If that's right, say yes.

The voice alarm is automatically added to the Google Clock app. To manage it later, open this app and go to the Alarm tab.

Important: for voice commands to work on Redmi 9, you must have access to a microphone for Google Assistant and an active Internet connection. If the command is not recognized, check the language settings in Settings → System → Language and input → Voice input.

4. Problem Solving: Why the Alarm is Not Working

Even after setting the alarm clock correctly on Redmi 9, here are the most common reasons and ways to fix them:

If none of these methods helped, try resetting the settings of the Watch app:

1. Go to Settings → Applications → Application Management → Watch.
2. Press Warehouse. → Clear the data.
3. Reboot your phone and set your alarm again.

5. The alarm clock on the phone turned off: myth or reality?

Many users are wondering if you can set your alarm to work even when the Redmi 9 is off. Unfortunately, this is not possible - when the phone is completely off, all processes (including the alarm clock) stop.

• 🔋 The alarm-setting mode of the plane turns off all wireless modules, but the phone stays on, the alarm goes off, and the battery runs out as little as possible.
• ⚡ Charging before bedtime – if you connect the Redmi 9 to the charger, the risk of discharge is reduced to zero, and the alarm will work exactly on time.
• ⏰ External alarm clock – if you need to wake up on time (for example, on a plane), use a separate device or a smart speaker (for example, Xiaomi Mi Smart Clock).

Some MIUI firmware has Auto-On, which starts the phone at a given time, but it's designed for updates and doesn't guarantee the alarm clock will work. Don't rely on it for important things!

💡

If you often forget to turn off your alarm clock on the weekend, set up an automatic shutdown via MacroDroid. Create a rule: "If it's Saturday or Sunday, it's Saturday or Sunday." → turn off all alarms".

6. Additional Alarming Functions on Xiaomi

The alarm clock on Redmi 9 can do much more than just make a sound. Here are some useful tips that many people don't know about:

• 🎶 Gradual volume increase – in the Google Clock app you can adjust a smooth increase in sound to wake up softer.
• 🌓 Backlit alarm clock – some third-party apps (such as Alarmy) can gradually increase the brightness of the screen before triggering.
• 📊 Sleep as Android has a sleep diary with phase graphs, which helps optimize the mode.
• 🔄 Delayed alarm clock – in the standard application, the clock can be set the number of repetitions and the interval (by default – 10 minutes).

Another useful feature is the location alarm, for example, in Google Clock, you can create an alarm clock that will work when you get close to work (geolocation is used), which is convenient if you drive and want to receive a reminder 15 minutes before you arrive.

The Redmi 9 also has Mi Band integration, so if you have a Xiaomi fitness bracelet, you can set the vibration alarm on it.

1. Open the Mi Fit app.
2. Go to the profile of the device → Alarm clock.
3. Add a new alarm clock and select the Vibration option on the bracelet.

7. Battery optimization for reliable alarm clock operation

One of the main reasons why the alarm doesn't work on the Redmi 9 is because of the aggressive battery optimization in MIUI, which can kill background processes, including the Watch app, to avoid this:

1. Add the app to exceptions: Settings → Battery and Performance → Battery Consumption Management → Select Apps → Watches → No Limits
2. Turn off battery savings overnight: Settings → Battery and performance → Battery savings → Schedule → Turn off
3. Check AutoRun: Settings → Applications → App Management → Watches → AutoRun (include)

Also, look for a Deep Sleep mode that is activated when the battery is low, so that the alarm goes off even at 5% charge:

1. Go to Settings → Battery and Performance → Battery Settings → Deep Sleep Mode.
2. Add the Clock app to the exclusion list.

💡

On the Redmi 9 with MIUI 13+ firmware, the alarm may not work if the phone is lying down on a soft surface (like a pillow), due to a proximity sensor that blocks the alarm. To avoid a problem, put the phone up with the screen or use a stand.
