How to set a timer to automatically turn off the Xiaomi phone: all ways

Have you ever fallen asleep with your phone in your hand and found a dead battery in the morning and a bunch of notifications? Or wanted to limit the time a child uses a gadget without conflicts? Xiaomi's automatic shutdown timer solves these tasks - but finding it in MIUI is not as easy as it seems. Depending on the model (Redmi Note 12, POCO X5, Xiaomi 13T) and the firmware version (MIUI 14/15), the ways are different, and some functions are hidden from the user.

In this article, 5 proven ways to set up a shutdown timer, including little-known tricks through Developer Settings and Google Assistant. We'll take a look at why a standard timer might not work on some devices (spoiler: power saving mode is to blame), and show you how to get around the restrictions. And for POCO and Black Shark owners, a separate bonus with Game Turbo setup.

Method 1: Built-in shutdown timer in MIUI (official method)

The most obvious, but most capricious way is to use the built-in MIUI feature, which is on most Xiaomi devices, but the path to it has changed in different versions of the firmware. Here is the current instruction for MIUI 14/15:

1. Open the Settings app (cog icon).
2. Go to Special Opportunities → Shutdown Timer. On some models (e.g. Redmi 10C), the path is different: Settings → System and Device → Additional → Shutdown Timer.
3. Activate the Timer Slider Shutdown and set the time (15 minutes to 12 hours).
4. Press Ready – the phone will turn off at the appointed time.

Challenges and solutions:

• 🔄 No "Switch off timer" item, which means your firmware is cropped for the region (e.g. Global). ROM For Europe, try the 3 or 4 method.
• ⚡ Timer resets after reboot - it's a bug MIUI 14.0.4 Update the firmware or use Google Assistant (method 5).
• 📵 Does not work in Do Not Disturb mode – turn it off before activating the timer.

Important: on devices with MediaTek Helio G (e.g. Redmi 9A), the built-in timer only works when connected to charging. This is a hardware limitation, and you can only circumvent it through ADB (mode 4).

Method 2: Timer through Digital Well-Being (for parental control)

If you need to not just turn off your phone, but limit your use (for example, for a child), use the Digital Well-Being feature, which is available in all Xiaomi on MIUI 12+ and allows you to set a hard shutdown on a schedule:

1. Go to Settings → Digital Well-Being and Parental Controls.
2. Choose Parental Controls → Set time limits.
3. Set up a schedule (for example, from 22:00 to 7:00 the phone will be locked).
4. Activate the option to turn off the device after the time has expired.

⚠️ Warning: If the phone has a second space set up (a dual account), the timer will only work for the current profile. ADB (4).

Method 3: Automatically shut down via "Sleep Mode" (hidden function)

Few people know, but MIUI has a hidden sleep mode that can turn off your phone on schedule, which is originally designed to save you energy at night, but it can be adapted to our tasks:

1. Open Settings → Battery and Performance → Sleep Mode.
2. Turn on the slider and set the time (for example, from 00:00 to 6:00).
3. Activate the option to turn off the device at the beginning of sleep mode (may be called Shutdown power).

Advantages of the method:

• ⏰ It works even if the phone is discharged to 5% (unlike the standard timer).
• 🔋 Save battery power by turning off the background.
• 📱 Not reset after rebooting.

On some models (Redmi A2, POCO M5) the function is hidden deeper:

If the built-in methods do not work (for example, on Xiaomi with custom firmware), you can use it. ADB-This requires you to connect the phone to the computer, but it gives you a 100% guarantee of operation.

Step-by-step:

1. Download Platform Tools from the Android website.
2. Turn on USB Debugging on your phone (Settings → About Phone → MIUI version – press 7 times, then go back to Additional → For Developers).
3. Connect your phone to your PC and type in the command line: adb shell am start -a android.intent.action.SHUTDOWN For delayed shutdown (e.g., after 30 minutes): adb shell "echo 'input keyevent 26' | at now + 30 minutes"

⚠️ Note: On some devices (Black Shark) 4/5, POCO F3 GT) ADB-In this case, only unlocking the bootloader will help (but this removes the warranty!).

Method 5: Voice timer via Google Assistant (the easiest)

If you don’t want to dig into the settings, use Google Assistant, which works for all Xiaomi services with Google (except Chinese firmware without GMS):

1. Activate Google Assistant by voice (OK, Google) or by holding the Home button.
2. Say, "Put the timer on the phone in 1 hour."
3. Confirm the command - the phone will turn off at the appointed time.

Features of the method:

• 🎤 It works even on a locked screen (if the option Voice Assistant from a locked screen is enabled).
• ⏱️ You can set a timer up to 12 hours.
• 🔌 Does not require rooting or ADB.

• "Set a timer to turn off the device."
• "Planning a shutdown for 23:00."

💡
