How to turn off the alarm on Xiaomi Redmi 9: all ways (including emergency)

Why the Redmi 9 alarm clock doesn’t turn off – and what to do about it

You woke up to the shrill signal of the Xiaomi Redmi 9, reached for the phone - and the screen does not respond to touch, the buttons do not work, and the sound of the alarm clock continues to cut your ears. Familiar situation? In this model (as in many Xiaomi smartphones on MIUI) there are features of alarm clock control that can play a cruel joke at the most inopportune moment.

To make matters worse, Redmi 9 often freezes when battery power is low or MIUI updates are up and the standard ways to turn off alarm clocks (swipe screen or press a button) stop working. In this article, we’ll discuss 5 proven methods, including emergency ones, that can turn off the sound even if the phone is not listening, and why the alarm clock can go off on its own — and how to prevent it.

Spoiler: The most reliable way is to press the power + volume button for 10 seconds, but it doesn't work in all versions of the firmware. Read on to find out the nuances.

Method 1: Standard shutdown through the lock screen

If your phone is responding to touch, but you don’t know where to press, follow this instruction:

1. Unlock the screen (if it's locked). On Redmi 9, the alarm goes off even when the screen is locked, but it may require unlocking to turn off.
2. Swipe left or right on the alarm. In MIUI 12-14, this is the main way to turn off.
3. If the swipe doesn’t work, click the Undo (or Stop) button at the bottom of the screen.

⚠️ Note: On some Xiaomi firmware, the alarm clock can stick if it is turned off too quickly. 3-5 seconds and repeat the action.

If the screen is completely frozen and does not react to anything, move on to the next method.

Method 2: Emergency button shutdown (if the screen is not working)

When the Redmi 9 touchscreen refuses to respond and the alarm goes off, all that remains is a hardware shutdown.

• 🔄 Short-term retention of the power button (3-5 - will cause the menu to reset. Sometimes this is enough to stop the alarm clock from sounding.
• 🔕 Long-term retention of the power button + volume upwards (10)+ It will force you to turn off your phone, even on locked devices. MIUI 12 and newer.
• 📵 Extraction SIM-cards (if the alarm clock is connected to the network) – rarely helps, but in 5% of cases the sound is lost.

⚠️ Warning: Forced button shutdowns can result in loss of unsaved data (e.g., if you edited a document before bedtime). MIUI 13+ This risk is minimal due to auto-saving.

Method 3: Turn off the alarm clock through settings (if it worked in advance)

Sometimes the alarm on Redmi 9 starts beeping 5-10 minutes before the set time (especially if you use the Watch app from Xiaomi).

1. Find an active alarm clock (in blue) and swipe it to the left.

If the alarm is created through Google Watch or another app, go to this app and turn off the signal there. Redmi 9 can set multiple alarm clocks at the same time from different sources!

💡

To avoid accidental alarms, set in Watch → Alarm → Settings set to Set aside – so you can quickly move the alarm for 5-10 minutes without completely switching off.

Method 4: Turn off the alarm clock sound through Do Not Disturb mode

If the alarm goes off, but you don’t want to turn it off completely (for example, you’re afraid to sing) – you can just mute the sound:

• 🔔 Quickly press the volume down button twice – this will put the phone in vibration mode.
• 📴 Activate Do Not Disturb via the notification panel (swipe down from the top edge of the screen).
• 🔇 In the settings Do not disturb (Settings) → Sound and vibration → Do not disturb) add an exception for alarm clocks, so that they sound even in quiet mode.

⚠️ Attention: Redmi 9s MIUI 12 and below Do Not Disturb can completely block the sound of the alarm clock – check this in advance in the settings!

Method 5: Radical measures - extraction SIM-card

If none of these methods worked and the alarm clock keeps screaming, extreme measures remain. On the Redmi 9 (unlike Xiaomi’s flagship models), it’s relatively easy to extract. SIM-A card or even a battery, but it can have consequences:

• 🔧 Extraction SIM-cards: Turn off the phone (if possible). Use a paper clip to retrieve the tray SIM-- The card (left-hand hole) SIM-map and reboot the phone.

Efficiency:

Battery extraction

1. Turn off the phone from charging.
2. Carefully put the back cover (it is on the latches, but easily breaks!).
3. Disconnect the battery plume for 10 seconds.

⚠️ Warning: Battery extraction on Redmi 9 voids Xiaomi warranty and can lead to data loss if the phone wasn't synced to Mi Account.Use this method only in a hopeless situation!

💡

Battery extraction is the last chance to turn off the alarm, but there are almost always safer ways. On a non-removable Redmi 9, it's better to use a combination of power and volume buttons.

Why Redmi 9’s alarm clock can go off on its own

If your Xiaomi Redmi 9 wakes you up in the middle of the night for no apparent reason, one of these factors may be the problem.

• 🕒 Time sync failure: The phone can "think" it's morning if the time settings are automatic (Settings) → System system → Date and time) disabled.
• 🔔 Duplicate alarm clocks: Simultaneous alarm clocks from Xiaomi Watch, Google Watch and third-party apps (e.g. Sleep as Android) can work at the same time).
• 🔄 Automatic updates: After update MIUI alarm clock settings are reset – check the alarm tab for the presence of “extra” signals.
• 📱 Firmware error: In versions MIUI 12.0.1-12.0.3 for Redmi 9 There was a bug that triggered alarm clocks spontaneously. MIUI 12.0.8+.

In extreme cases, use a power button combination + volume up (10 seconds) to force a reboot.
