Redmi smartphones have been among the most popular devices in the world for many years, thanks to their excellent value for money. The Redmi 8, launched in 2019, is still widely used by millions of people as a reliable working tool or device for children and the elderly. One of the basic but critical features of any phone is the ability to wake the owner in time or remind them of an important event.
But Xiaomi’s MIUI has its own unique system application management features that can confuse a newcomer who has switched from a different brand. The standard Watch app here has advanced functionality that goes far beyond simply displaying time. In this article, we’ll go into detail about the signal setup process, its fine-tuning, and solving common problems when the device is silent at the right time.
Understanding the logic of the alarm clock in the Mi ecosystem will allow you not only to wake up on time, but also to use timers and stopwatches with maximum efficiency. We will look at hidden settings that often go unnoticed, but greatly improve usability. Let's start to fine-tune your personal time manager.
Standard Watch application and its interface
At the heart of all temporary functions on Xiaomi Redmi 8 is a system application, which is called by default “Clock” and is deeply integrated into the Android operating system with the MIUI add-on, which ensures its stable operation even in closed background processes. The application icon is usually an analog dial and is located on the main screen or in the Tools folder.
When you first run, you'll see the bottom navigation bar divided into four main tabs: "Alarm clock", "Clock" (world time), "Timer" and "Secondomeric" -- and we're interested in the first tab, which is marked by the icon of the classic alarm clock, and the interface is designed in a minimalist style, where each control has a clear graphical designation.
It's worth noting that the visual design may vary slightly from one version of MIUI firmware to another, but the logic remains the same. The system application takes precedence over third-party counterparts, so it's better to use the built-in tool for reliability. If you deleted it accidentally, recovery is only possible through resetting or flashing, since it's a system component.
⚠️ Warning: Do not delete the Clock system application through third-party managers, even if the phone suggests doing so.This can lead to incorrect timers in other programs and time synchronization failures.
To start with the signal, you need to go to the main alarm tab, which shows a list of all active and disabled signals, and if the list is empty, you will see a large button with a plus image or the inscription "Add an alarm clock", usually located at the bottom of the screen or in the center.
Step-by-step setting a new signal
The process of creating a new reminder on Redmi 8 is as simple as possible and takes only a few seconds. After clicking on the add button (plus), you will see the time setting interface. The default setting is the current time with the addition of one hour, but these values can be easily changed.
At the top of the screen is a digital drum or input field where you set the hours and minutes. Swipe up or down, you change the values. In some versions of the interface, you can switch between the 12-hour and 24-hour format, which is especially important to avoid confusion with the time of day (AM/PM).
☑️ Algorithm of alarm clock setting
Below are the switches for selecting the days of repetition, you can select specific days of the week (for example, weekdays only), or leave the signal one-time. Also here is the activation slider: if it is turned off, the alarm will remain on the list, but will not work at the appointed time.
And you should pay special attention to the "Repeat" button, which, unlike older phones, you can flexibly adjust cycling, for example, you can set up a single alarm clock at 7:00 and set it up on Mondays, Wednesdays and Fridays without creating three separate signals, which saves RAM resources and makes it easier to manage the list.
Customization of melody, vibration and volume
One of the key features of MIUI is the advanced audio notification editor, which, if you click on "Melody" or "Sound", you'll be taken to a library where you can choose not only standard ringtones, but also tracks from your music collection, which allows you to use your favorite song or even a voice reminder as a signal.
The vibration setting is important. The audio menu often has a separate "Vibration" switch. If the phone is in silent mode, the vibration response will help you stay awake. The Redmi 8 has a high-quality vibrator motor that provides tangible tactile return even through the case.
- 🎵 Melody Choice: Click on the current track title to open the list of available audio files.
- 📳 Vibration adjustment: You can choose a standard pattern or create your own pulse rhythm.
- 🔊 Alarm Loudness: Adjusted by a separate slider, independent of media volume or bell.
There's a useful feature called "Alarm Loudness," which allows you to gradually increase the sound, which prevents you from suddenly waking up from a loud alarm if you're in deep sleep, and this is especially relevant for people with sensitive hearing or for use in quiet offices.
⚠️ Note: If you choose your music as a signal, make sure the file is not deleted from the memory card and has a supported format (MP3, AAC, OGG). Otherwise, the alarm clock can go off without sound.
Use the "Delay" and "Call" function
When the alarm goes off, the notification interface is displayed on the Xiaomi screen, and there are two main buttons available: "Finish" (or cross) and "Delay." The delay function allows you to move the signal forward 5, 10 or 15 minutes, which is convenient for those who like to sleep for another "five minutes."
The replay interval is set up in the general settings of the application, and you have to click on three dots in the corner of the screen or the settings icon (cog) inside the alarm interface, and you can select the time interval through which the phone will remind itself again.
💡
Set the 9-minute delay interval, which is the physiologically optimal time for a short sleep, allowing the brain to reboot a little, but not go into the deep phase of sleep.
And it's also worth mentioning the behavior of the phone when the screen is locked, so if the phone is down or in your pocket, the sound will play and the vibration will work, but you won't see the visual interface until you unlock the device. This is standard Android security behavior.
Advanced settings and automation
The MIUI shell offers features that go beyond just calling, and you can find the alarm settings for "Switch off the alarm itself." If you activate this mode, the phone will stop ringing after a certain time (for example, 10 minutes), even if you haven't touched it, which is useful if you're afraid to forget to turn off the alarm and go to work.
Another interesting feature is the Smart Alarm, which uses an accelerometer and activity data to wake you up in REM sleep within a set time window (e.g., 7:00 to 7:30), which is thought to be easier to tolerate.
For those who like order, alarm clocks can be sorted, arranged chronologically or by day of the week, and system resources are distributed so that even with a large number of signals set, there is no delay in activation.
| Parameter | Description | Recommendation |
|---|---|---|
| Repeat. | Days of the week to trigger | Use for working days |
| Put off | Time for naptime | Optimum 5-10 minutes |
| Vibration. | Tactical response | Always switch on for reliability |
| Auto-switch-off | Stopping sound over time | Turn on if there is a risk of falling asleep |
What to do if the alarm clock doesn’t ring
Sometimes users are faced with a situation where the phone is silent at the appointed time, most often the problem lies in the power saving settings. Aggressive battery optimization on Xiaomi can kill background processes, including the watch app, if it does not have the appropriate permissions.
To solve this problem, you need to go to the settings of the Clock application through the application management menu. Find the "Sunset" item and make sure that it is on for the watch. Also, in the "Energy Saving" section, for this application, you need to select the "No Limits" mode.
The Hidden Reasons for the Silence of the Alarm Switch
Another reason could be the human factor: the phone was turned off. On most modern smartphones, including the Redmi 8, the alarm clock will not work if the device is completely turned off (although some models can turn on themselves for this, but you should not rely on it).
Removing and editing existing signals
The alarm list is controlled by swiping (finger swiping) on the list item. Swipe left or right (depending on the MIUI version) usually opens the edit button (pencil) and delete button (basket), a standard gesture for mobile interfaces.
When editing, you can change the time, the melody, or the days of repetition without having to create a new signal, which is especially useful when you switch to winter/summer time or change your schedule. All changes are saved instantly.
- ✏️ Editing: Click on the pencil icon or swipe on the alarm clock.
- 🗑️ Delete: Click on the red basket icon or minus icon.
- 🔄 Copying: Some versions have a signal duplication function to quickly adjust similar times.
⚠️ Attention: When the alarm clock is removed, it disappears irrevocably. If the signal was complex (with individual melody and vibration), it will be possible to restore its settings only manually.
