Auto-disabling alarm on Xiaomi: how it works and why you need it

Have you ever woken up from an alarm clock on Xiaomi but it turned off after a few minutes? Or did it keep ringing until you picked up your phone? This is the job of the alarm clock auto-switching, one of the most useful but often underrated features of MIUI. In this article, we'll look at what it is, how it affects your sleep and morning rise, and why sometimes the alarm clock doesn't behave as you expect.

The auto-disconnect feature didn't come out of Xiaomi's firmware immediately, but it's now available on most models, from the budget Redmi Note to the flagship Xiaomi 14. Its main goal is to prevent the alarm clock from sounding endlessly if you don't respond to the alarm. But how exactly does it work? Why does the alarm sometimes go off too quickly, and sometimes it doesn't stop ringing at all? And most importantly, how do you set it up to your needs?

What is the Auto-Switching Alarm on Xiaomi?

An alarm clock auto-turning is a feature in MIUI that automatically stops the alarm clock after a predetermined period of time if the user has not interacted with the device. By default, on most Xiaomi smartphones, the alarm clock rings for 10 minutes, then turns off itself.

Why do you need it? Imagine if you set your alarm for 7:00 but you overslept. If you don't shut down, your phone will ring until your battery runs out or you wake up. With hitchhiking, the signal will stop in 5 to 30 minutes (depending on your settings), which will save you charge and not disturb others, especially for those who live in a dorm or with family.

• 🔔 By default: The alarm clock rings for 10 minutes, then shuts down.
• ⏱️ Customizable timer: you can set from 1 to 60 minutes.
• 🚫 Disabling function: The alarm clock will ring before manually switching off.
• 🔋 Battery savings: prevents battery discharge from long signal.

It is important to understand that auto-disconnect only works for the standard watch app (com.android.deskclock).If you use third-party alarms (such as Google Clock or Sleep as Android), the settings may differ or not at all.

Where is the setting of auto-disconnection in MIUI

To find and change auto-disconnect settings, follow the following steps:

1. Open the "Clock" app (icon with dial).
2. Go to the Alarming Signal tab (bell icon at the bottom of the screen).
3. Press on. ⋮ (three dots) in the upper right corner and select Settings.
4. Scroll down to the Auto-Switching Alarms section.

Here you will see a slider or a drop-down menu with time options. The options available depend on the version of MIUI:

Some firmware (e.g. Xiaomi.eu) may have an advanced Smart Auto Shutdown mode, in which case the alarm analyzes your activity: if you pick up your phone or start moving, the signal will last longer.

Open the app "Clock" | Go to the "Alarm clock" | Press three points → "Settings" | Find the item "Alarm clock Auto-Switch" | Choose the right time or disable the function-->

Why Xiaomi’s alarm clock doesn’t automatically turn off

Sometimes users are faced with the alarm clock continuing to ring despite the on auto-disconnection.

• 🔄 Failure to work MIUI: temporary system glitch, which is solved by restarting.
• 📱 Third-party alarm clock: if you are using a non-native app, settings MIUI it is not subject to.
• 🔋 Energy saving: aggressive battery settings can block background work".
• 🛠️ Wrong settings: You may have accidentally turned off hitchhiking or picked too long a time.
• 📲 Update of the firmware: after the update MIUI settings may reset.

If the alarm doesn’t go off, check:

1. Is the standard "Clock" application running (not a duplicate)?
2. Shouldn't the phone be in Do Not Disturb mode with alarm clock exceptions?
3. Does not block Security → Optimization of the battery work of the application background?

⚠️ Note: On some models (e.g, POCO F5 or Redmi K60) After upgrading to HyperOS, auto-disconnect settings may be located elsewhere: → Sound and vibration → If you don't find an option in "The Watch," check this path.

How to set up auto-disconnection for your needs

The optimal auto-switch time depends on your habits:

• 😴 Sleep well: set 20-30 minutes – it’s enough to wake up.
• ⏰ Light sleep: 5-10 minutes is enough, otherwise the alarm clock will interfere with others.
• 🏃 Morning jog: Turn off hitchhiking so the signal rings before you wake up.
• 👨‍👩‍👧 Family/Neighborhood: Choose 15 Minutes as a Compromise Between Reliability and Silence.

If you want the alarm to never go off on its own, select the option to turn off hitchhiking (if available in your firmware).

• The phone will ring until the battery is completely discharged unless you turn off the signal.
• The risk of disturbing others is much higher.
• With a long signal, the heat protection of the speaker can work.

💡

If you wake up frequently from your alarm clock but then fall asleep again, try the "Repeat Beep" function in the alarm settings, which will allow the alarm to repeat 5-10 minutes after the first shutdown.

Frequent Mistakes and How to Avoid Them

Many Xiaomi users are facing problems because of the wrong actions.

1. Using two alarm clocks at the same time. If you have both a standard clock and a Google Clock, for example, their signals may conflict. MIUI prioritizes the native app, but third-party alarms can ignore the auto-disconnect settings.
2. Activate Do Not Disturb mode with no exceptions. If the Do Not Disturb settings do not add an alarm clock as an exception, it will not ring at all.
3. Resets after the update. After major updates (e.g., from MIUI 13 to MIUI 14), the alarm clock settings may reset to factory settings. Always check them after the update.
4. Ignoring permissions for "Clock" If you deny the app access to the Microphone or Notifications, it can affect the alarm clock.

To avoid problems:

• 🔍 Check your alarm settings regularly after updates.
• 📵 Remove unnecessary alarm apps to avoid conflicts.
• 🔋 Add "Clock" to the list of Protected apps in battery settings.

⚠️ Note: Some models (e.g. Xiaomi) 13T Or the Redmi Note 12 Pro.+) When you activate Gamer Mode (in performance settings), the alarm may not work at all, and this mode blocks all notifications, including wake-up signals.

Auto-disconnect alarm clock on smart watches and fitness bracelets Xiaomi

If you use the Mi Band, Xiaomi Watch or other wearable devices of the brand, there is also the function of auto-switching the alarm clock, but it works differently than on smartphones:

• ⌚ Mi Band 7/8: alarm clock 10 It's a second with vibration, then it shuts down.
• 📱 Xiaomi Watch S3: You can set up up to 3 repetitions with an interval of 5 minutes.
• 🔋 Redmi Watch 3: Auto Shutdown is fixed – 30 seconds, can not be changed.

To set the alarm clock on a smart watch:

1. Open the Mi Fitness or Zepp Life app on your smartphone.
2. Go to the Profile section → My device. → Alarm clock.
3. Add a new alarm and select vibration/repeat options.

Important: The alarm clock and the smartphone work independently, and if you set the alarm on both devices, they may not work in sync, leading to a double wake-up.

💡

On Xiaomi smartwatches, the alarm clock auto-switch is usually shorter than on smartphones, which is done to save battery power, as the vibration and screen consume a lot of energy.

Alternative ways to control the alarm clock on Xiaomi
