Smartphone personalization starts with little things, and setting up an alarm clock is one of the first steps to a comfortable experience with a device. Smartphone owners Xiaomi, Redmi and Poco often face the need to replace the standard, boring "sound" with something more pleasant or motivating. The MIUI shell or its new version HyperOS offers flexible tools for managing multimedia, but they are not always obvious to the beginner.
It’s important to understand that the process may vary depending on the version of the Android operating system and the specific model of your gadget. For example, on older models like the Redmi Note 8, the algorithm of actions will be slightly different from the current Xiaomi 14. But the basic logic of the Watch app has remained the same for years, and you don't need superuser rights or complex ones. ADB-team to accomplish this task.
Before you start settings, make sure that the audio file you want is already stored in your device’s memory. This can be your favorite song downloaded from a streaming service, or a voice recording you created yourself. Xiaomi can work with MP3, M4A and WAV formats, but for maximum compatibility, it is better to use the classic MP3. If the file is in the cloud, pre-upload it to local storage.
To get started, open the standard Clock app on the home screen or in the Tools folder. It has an analog dial icon, and inside you'll see a list of alarm clocks you've already created, or a new add button, if none are set up, and that's where we're going to do all the major manipulations in the interface of this app.
⚠️ Note: Some system sounds are copyrighted or shell-restricted, so they cannot be replaced with custom tracks without using third-party software.
Selecting a standard melody from the system list
The easiest way to change the sound is to use the built-in library that you already have in your phone. Xiaomi provides a wide range of pre-installed songs, divided into categories, which can be classic tunes, natural sounds or modern rhythm tracks, specially selected by the developers.
To select a standard sound, click on an existing alarm clock to edit or create a new one. Find a line with the current tune's name (usually "Default" or track name) and tap it. The selection menu will open, where you can listen to the available options. Click on any track to hear the preview before installation.
At the top of the list are often the "Recommended" sounds that the system considers most suitable for waking up. Below are categories like "Retro", "Nature" or "Electronics", and the user can select any of them by simply tapping the name, after which the system will automatically return to the alarm settings menu with the updated setting.
If none of these options suit you, don't rush to close the menu. At the bottom of the standard melodies list, there's often (but not always) a "Select Music" or "Local Track" button that will take you to the file manager. However, a different method, described below, is more reliable for downloading your own files.
Installation of your own MP3-alarm-file
Using your own music file is the best way to make the awakening personal. Unlike call ringtones, which require moving files to system folders, setting the track to an alarm clock in MIUI is much easier and straight from the application interface.
Open the settings of a specific alarm clock and click on "Sound" (or note icon). In the menu that opens, select "Select music" or "Local music". The system will prompt you to choose a source: this can be an embedded Music player, file manager or third-party applications like Spotify or Yandex.Music, if they support local files.
Once you select the source, you will open a list of tracks, sorted by folder or performer. Find the file you want, tap it, and it will set as the default signal for that particular alarm clock. that you can set different tunes for different alarm clocks (e.g., soft for rising at 7:00 and sharp for 7:15).
In some firmware versions, especially on the global versions of HyperOS, the path may be slightly different. If you don't see the music selection button right away, try pressing the three dots in the upper right corner of the alarm menu and selecting "Sound settings." There should be a switch between System and Local sounds.
☑️ Pre-installing check
Loudness and sound behavior setting
It's not enough to just pick a track, it's important to set up how it's going to play. In Xiaomi smartphones, the volume of the alarm is separated from the volume of the media and the call, which allows you to flexibly manage the audio profile. You can make the alarm wake you up loudly, but the video on YouTube is played quietly.
In the alarm clock editing menu, find the volume slider, and when you move it, you change the sound level for that particular signal, and you often have the "Rise Volume" feature available here, and if it's on, the alarm clock will start to sound quiet and gradually increase the volume over a selected time (e.g., 1 or 5 minutes), which helps wake up more gently.
Note the Vibration switch. It can pair with the sound or replace it in quiet modes. In advanced settings (often hidden under the "More" button or gear), you can find the "Use system sounds." If you turn off this focus, the alarm clock will ignore the track you choose and play the standard system squeak, which is useful in emergency situations when you need to guarantee to wake the person.
| Parameter | Description | Recommendation |
|---|---|---|
| Loudness | Signal sound level | Set the maximum for guaranteed awakening |
| Growth | Smooth volume increase | Insert for a soft awakening (1-3 minutes) |
| Vibration. | Tactical response | Turn on if the phone is lying far away or in your pocket |
| Repeat. | Activation week days | Make sure the alarm doesn’t ring on the weekend. |
⚠️ Note: If you have Do Not Disturb or Silent Mode enabled, the alarm should still work, but make sure that the settings of this mode do not prohibit the playback of the alarm clock sounds.
Use of voice recordings and voice recorder
The unique feature of MIUI is that it uses tape recordings as an alarm clock, and it allows you to create a personalized message, like a loved one's voice or your own motivating phrase, and this is especially true for people with hearing impairments or those who only respond to familiar timbres.
To do this, first open the Dictaphone app and write down the snippet you want. Save the recording. Then go to the alarm settings, select "Sound" -> "Select Music." In the source list, find the Dictaphone or Recordings folder. Your recordings will appear there as regular audio files.
The recording you select will play back in cycles until you turn off the alarm clock, which is a great way to add a variety. Unfortunately, you can't record the sound directly from the alarm clock interface on the fly, you have to record it in advance.
What do I do if the recording is broken?
Sound problems and their solution
Sometimes users are faced with a situation where the alarm clock rings the wrong track, or there is no sound at all. Most often the problem lies in the permissions of the application "Clock" to the file system. After the Android update, the security system becomes stricter and can block access to new folders with music.
Go to Settings -> Apps -> All Apps. Go to "Clock." Go to "Application Permissions." Make sure you have permission to access "Music and Audio" or "Files and Media Content." Without that permission, the app simply won't be able to "see" your downloaded track.
Another common reason is that the memory is cleaned by third-party utilities ("cleaners"). If you use aggressive power saving or auto-cleaning settings, the alarm clock process can be stopped by the system before the call. Add the "Clock" app to the exception list or fix it in memory (lock in the menu of running applications).
It’s also worth checking if the phone is in “Vibration Only” mode at the hardware level (a switch on the case, if any, or a software slider in the notification curtain). Although alarm clocks usually ignore the sound profile, this rule may work differently in some custom MIUI builds.
💡
Tip: If you use a Bluetooth headset or speaker, check the audio output settings. The alarm clock may try to play through a connected device that is turned off or lying in another room at that moment.
Features of work in sleep and energy saving mode
Xiaomi smartphones are famous for their power optimization, which is sometimes unnecessarily aggressive. In deep sleep or “full discharge” mode (with 5-10% of the battery left), the system can limit background processes, which can lead to the alarm clock not ringing on time or ringing with a delay.
To avoid this, you need to set up auto-start for the Clock app. Go to Settings -> Apps -> Auto-Start. Find the Clock and turn on the switch, which will tell the system to always keep the alarm clock running, even if the phone is idle for several hours.
There is also a “Switched Off” alarm (not available on all models, mostly older or specific versions of the software) feature that allows the phone to turn on itself at a given time to act as an alarm, even if you forgot to turn on the device the day before.
💡
Main conclusion: To guarantee the alarm clock on Xiaomi, be sure to give the app "Clock" permission to start and access files, and also exclude it from the lists of aggressive energy saving.
