Xiaomi smartphone does not turn off when you press the power button – what to do?

You press the Xiaomi shutdown button, hold it for a few seconds, but nothing happens: the screen doesn't go out, the shutdown menu doesn't appear, and the device continues to work as if nothing had happened. Is the situation familiar? This problem occurs on models from the Redmi Note 10 Pro to the flagship Xiaomi 13 Ultra, and there can be a dozen reasons for it, from banal system freezes to serious hardware breakdowns.

In this article, we’ll look at all the possible reasons why Xiaomi doesn’t respond to the power button, from software failures to mechanical damage. You will learn how to diagnose the problem yourself, which manipulations should be tried first, and when it is better to immediately carry the phone to the service. MIUI, which can block the shutdown, and common user errors that make the situation worse.

Note: If your smartphone doesn't just turn off, but also spontaneously turns on, overheats or discharges in an hour, these are signs of a deeper malfunction, in which case read the article to the end: in the last section, we will give a checklist for comprehensive diagnostics.

1.System freeze: when MIUI is "deaf" to teams

The most common reason Xiaomi doesn't turn off the button is because the operating system freezes, which can happen after installing an update, an application conflict, or overloading RAM. Symptoms: the screen doesn't respond to touch, the control buttons don't work, and sometimes even vibrates when you press, but doesn't act.

In 70 percent of cases, a forced reset helps.

1. Hold the power button for 10-15 seconds (even if it usually takes 3-5).
2. If the screen is gone, but the phone is back on, repeat the hold again.
3. Some models (e.g. POCO F3) have a power + volume combination up 20 seconds.

Important: If the problem repeats after the reboot, it's a system failure signal. Try going to Safe Mode (hold the off button → long tap on "Stop" → "Safe Mode") and check the button response. If safe mode is working, it's the third-party app's fault.

2. firmware failures: when the update breaks the power button

Firmware errors are the second most common cause, especially for devices that have recently received a major MIUI update (e.g., switching from MIUI 13 to MIUI 14).

• 🔄 The power button works every once in a while (sometimes it turns off, sometimes it doesn't).
• 📱 The off menu appears, but when you select “off” nothing happens.
• 🔋 The phone is turned off, but it is turned back on immediately.

Decisions:

1. Update rollback: Go to Settings → About Phone → System Update, tap the three points at the top → “Delete the latest update.”
2. Reset: If you can’t roll back, reset via Settings → Additional → Reset and Reset → Reset settings (the data won’t be affected).
3. Manual firmware: Download the stable version of MIUI for your model from the official website and run through Fastboot.

⚠️ Warning: If after firmware the phone stopped turning on at all (black screen, no vibration), do not try to flash it again - this may block the bootloader. EDL Mode.

3. Mechanical damage to the power button

Physical breakage of a button is a common problem after falls, moisture or prolonged use.

• 🔊 The button "fails" or presses with a crunch.
• 💧 The phone was in contact with water (even if it was a few days later).
• 📉 The reaction to the press appears only at a certain angle.

How to check:

1. Light a flashlight on the button – if you see condensation or oxidation, it is 100% moisture.
2. Try pressing the button with a toothpick (carefully!): if it works, then the contact has gone.
3. Connect your phone to your PC and try to turn it off via ADB: adb shell reboot -p If the command worked and the button didn't, the problem is precisely hardware.

⚠️ Warning: If the phone falls into water, don't dry it with a hair dryer or battery, it will speed up the corrosion of the contacts. Optimal: put it in a silica gel bag (from a shoebox) for 24 hours, then check the button.

4. Application conflict: who blocks the shutdown?

Some apps can block the phone from turning off through system permissions, most often to blame:

• 🔒 Antiviruses (Avast, 360 Security).
• 📱 Optimizers (Clean Master, DU Speed Booster).
• 🎮 GameGuardian, Freedom (Freedom).
• 🔄 Automators (Tasker, MacroDroid).

How to find the culprit:

1. Start your phone in Safe Mode (hold the shutdown button → long tap on “Switch off”).
2. If the button is running in Safe Mode, delete the apps one at a time, starting with the last ones installed.
3. Check permissions: Settings → Apps → Permissions → Special Accesses → Device Administration. Disable suspicious apps.

Hidden MIUI setting: Some firmware has a “Disable Shutdown” option that is activated via Settings → Battery → Power Saving Mode → Additional. Make sure there’s no tick opposite “Block Shutdown.”

5. Failures in the operation of the power controller

The power controller (PMIC) controls the power supply to all components of the phone, including the power button. If it fails, the phone can:

• 🔋 Do not turn off the button, but discharge in 10 minutes.
• 🔌 Independently turn on after switching off.
• 🌡️ Overheating, even in standby mode.

Diagnosis:

⚠️ Warning: If the phone turns on immediately after switching off with a characteristic click, it is a sign of a short circuit in the power supply chain!

💡

Before visiting the service, take a picture of the IMEI of the phone (on the box or in the About Phone settings → General information).

6. MIUI software "features" that interfere with shutdown

Xiaomi adds features to the firmware that sometimes conflict with basic operations.

• 🔄 Automatic alarm clock: If the alarm clock is set, the phone can ignore the shutdown.
• 📡 Do Not Disturb Mode with Exceptions: Some Notifications May Wake Up the Device.
• 🔋 Smart charging: In the battery settings, the option “Do not turn off when connecting to charging” can be activated».

How to turn it off:

1. Check the alarm clock: Clock → Alarm clock → remove all active.
2. Turn off smart charging: Settings → Battery → Battery settings → Smart charging.
3. Reset the “Do Not Disturb” settings: Settings → Sounds and vibrations → Do Not Disturb → Reset settings.

Hidden Developer Mode: Sometimes the problem is settings for developers to reset:

1. Activate Developer Mode (7 times tap the MIUI version in About Phone).
2. Go to Settings → Additional → For developers.
3. Find the option “Disable MIUI Optimization” and deactivate it.
4. Perform reboot.

💡

If the phone does not turn off only when the charger is connected, the Do not turn off when charging in the battery menu is to blame.

7. When is it time to bring the phone to the service?

If you've tried all the ways, but Xiaomi still doesn't turn off, it's time to contact the experts.

• 🔥 Phone warms to 50°C+ In simple (check through the settings). → The phone. → Battery status).
• 💥 There is a smell of burning or smoke from the speakers.
• 🔌 The phone is turned on/off in a cycle (bootloop).
• 🛠️ The power button is "recessed" or does not return to its original position.

What to do before visiting the service:

1. Backup: Connect your phone to your PC and copy the data via MTP or Xiaomi Cloud.
2. Write down the IMEI: Type *#06# or look at the box.
3. Learn the motherboard model: This will help the wizard find parts faster, and you can find out through the CPU-Z app (Hardware → Model).

⚠️ Warning: If the phone is warranty, do not open it and do not sew it yourself - this will void the warranty.
