Modern smartphones, especially those based on MIUI and HyperOS, are oversaturated with features designed to improve the user experience, but often they are only annoying. One of these features is a smart alarm clock that tries to wake you up at the "right" time, based on appointment schedules or sleep phase analysis. For many users, this option becomes a real challenge, as the phone starts ringing when it needs to, or offers unnecessary actions immediately after waking up.
Fortunately, Android, even in a deep version from Xiaomi, allows you to flexibly adjust the behavior of system applications. In this article, we will discuss how to turn off the smart alarm on Xiaomi, regaining full control of the morning wake up, you will learn where hidden settings hide and how to prevent accidental activation of unnecessary functions in the future.
Before we go into radical measures, it is worth understanding what causes discomfort, most often it is the function of the Smart Alarm Watch in the Security app or the specific settings in the standard Watch app. Different models and versions of firmware can have their own characteristics, so we will consider all possible scenarios so that you are guaranteed to solve the problem.
⚠️ Warning: Before making changes to system settings, it is recommended to make sure that you have a battery charged so that during the setup process the phone does not suddenly turn off and knock down the current time settings.
Why Xiaomi Wakes You Up in Time: The Essence of Smart Features
MIUI's philosophy is to automate your processes as much as possible. It analyzes your habits, calendar, and even your location to suggest the most "effective" scenario of the day. A smart alarm is part of an ecosystem that's designed to wake you up during the light phase of sleep or earlier if traffic jams are expected. However, algorithms often get it wrong, and instead of helping, the user gets stressed by an unexpected call.
The main problem is the integration of system services: the function can be activated by default when the phone is first turned on or after a major firmware update. Intelligent schedules often conflict with conventional alarm clocks, creating duplication of signals or, conversely, canceling them. Understanding the logic of the system helps to find the right switch faster.
And then there's the difference between Smart Alarm as a standalone feature and Smart Mode in a standard application, the first one being a service that wakes you up early, and the second one being a function that wakes you up when you wake up (which is not always convenient), and we're going to turn off the intrusive automation services.
Disconnection through the "Security" application
The most common source of intrusive notifications and smart features on Xiaomi and Redmi devices is the built-in Security app. This is where global optimization settings, including power management and smart alarms, often hide. To access these settings, you need to find a green shield icon on the home screen or in the Tools folder.
After you start the app, scroll down to Battery or Optimization. In some versions of the shell, the option you want is in the Settings menu (the gear icon in the corner). Here you should look for an item related to standby or smart wake-up. The name may vary depending on the regional version of the firmware (Global, Chinese, European).
If you find a smart alarm or a smart alarm, just turn the slider to off. This action completely deactivates the algorithm that tries to guess your wake-up time, and then the phone will run strictly according to the schedule you set in the Clock app.
☑️ Checking security settings
Setting up the standard application "Clock"
If the problem is not resolved through the security center, you need to look at the native app "Clock" This is where the immediate settings of the alarm clocks are stored. Open the app and look at the three dots in the upper right corner or the menu button. Go to the section "Settings".
In the settings menu, look for an option called Smart Alarm or Smart wake-up. This feature can use an accelerometer to detect your movements to wake you up in REM sleep. Turning off this feature will return the alarm clock to the classic behavior: calling at exactly the right time, without the system trying to "improve" the process.
Note the "Behavior when calling" section. Some versions of MIUI offer options like "Be on working days only" or "Skipping holidays." Make sure these checkmarks are removed if you want the alarm to ring always, ignoring the calendar, which is especially true for those with non-standard work schedules.
⚠️ Warning: After changing the settings in the Watch app, make sure to check if the alarm itself has been set. In rare cases, the system can deactivate a specific alarm clock when global parameters change.
Management of notifications and data access
Sometimes, a smart alarm is not a system function, but the result of a third-party Google app or service that has access to your calendar and alarm clock. To rule this out, go to Settings → Apps → All Apps. Find the Watch or Security app on the list.
Inside the app card, go to Notifications, where you can configure in detail what notifications are allowed, disable anything related to recommendations, tips or smart tips, leave only critical alarm notifications, which will clear the interface of unnecessary information noise.
It’s also worth checking permissions to access data. Go to Settings → Applications → Permissions → Autonomous Start. Make sure the Clock app has permission to autorun, but there are no unnecessary permissions to use data in the background unless it’s required for synchronization.
Google's Hidden Services
Comparison of MIUI and HyperOS versions
The interface and settings can vary significantly depending on the operating system version. HyperOS, which replaced MIUI, has changed the menu structure to make some functions more hidden or renamed. Understanding the differences will help you find the desired item faster.
| Function | Location at MIUI 12/13 | Location in HyperOS/MIUI 14 | Action. |
|---|---|---|---|
| Smart alarm clock | Security appendix → Battery | Settings → Battery and productivity | Turn off the slider |
| Sleep regimen | The clock → Settings → Sleep regimen | The clock → The alarm clock tab → Settings | Delete the schedule |
| Notifications | Settings → Notifications | Settings → Notifications and Status Bar | Limit for the Clock |
| Digital well-being | Settings → Digital well-being | Settings → Screen time | Check limits |
In new firmware versions, Xiaomi is actively implementing Digital Wellbeing, which can block apps or change alarm behavior depending on your “Do Not Disturb” or “Sleep” mode. Check the settings in Settings → Screen Time. If it has a tightly restricted sleep mode, it can affect the alarm clock.
Users of older devices based on MIUI 11 and below should pay attention to the topic of design. Some third-party themes can change the functionality of system applications by adding their alarm widgets, in which case resetting the theme to the standard "Classic".
💡
Use search in settings: At the top of the settings menu, there is a search bar. Type the word "alarm" or "alarm" into it, and the system will show all the available switches associated with that word, regardless of their location in the menu.
Solving problems with third-party applications
Often users set third-party alarms from Google Play that require advanced resolutions. Apps like Alarmy or Sleep Cycle can conflict with Xiaomi's standard alarm clock. If you don't use them actively, it's best to delete or disable them.
Check the list of installed applications for duplicates. If you have multiple alarm apps installed, the system may be confused as to which one is the most important. Leave only one main application. To remove, go to Settings → Applications → Application Management, select the unnecessary one, and click "Delete".
If deletion is impossible (system application), try to clear its data. Go to the application card, select Memory and click Clear. This will return the alarm settings to factory settings, removing all user configurations that may have caused the smart functions to malfunction.
⚠️ Caution: Clearing the Clock data will remove all alarm clocks and timers you have set, and be sure to record or screenshot an important schedule before performing this operation.
💡
Application conflict is a common cause of malfunctioning alarm clocks, and removing third-party software often solves the problem of smart behavior.
