How to turn on Xiaomi smartphone if the power button does not work: all the ways from charging to disassembling

A broken power button on Xiaomi is one of the most unpleasant things that can happen to a smartphone. Without it, the device becomes a brick: it does not respond to charging, it does not turn on, and access to data seems impossible. However, not all that bad, there are at least 7 ways to revive the device without physically pressing a button, some of which work even on fully discharged phones, others require preliminary preparation.

In this article, we will discuss all the current methods - from basic (charging, connecting to a PC) to advanced (disassembling the case and closing contacts). Particular attention will be paid to Redmi models, POCO and flagship Xiaomi 11/12/13 series, because their design has nuances, you will also learn how to avoid data loss and when to carry the phone to the service.

⚠️ Important: If your Xiaomi falls into water or suffers mechanical damage (cracks on the body, dents), none of the described methods may work. In this case, a card diagnosis is required - self-manipulation will only aggravate the problem.

1. Charging as a way of turning on - does it work?

The most obvious method is to plug your smartphone into the charger and wait, but there are three critical nuances that determine success:

✅ It works if:

• 🔋 The battery is completely discharged, but the power button is physically intact (just not pressed due to contamination or wear and tear).
• 🔌 Used original cable and power supply (cheap accessories may not give enough current).
• 📱 Xiaomi phone supports Quick Charge (fast charging often wakes up the power controller).

❌ It doesn't work if:

• 💀 The power button has soldered off the fee or the track has been damaged.
• 🔋 Battery is swelling or out of order (replacement needed).
• 📵 The phone was turned off software (for example, via adb reboot). -p).

🔹 How to charge properly:

1. Connect Xiaomi to charging and leave for 15-30 minutes (even if the indicator is not on).
2. Try pressing and holding the volume button for 10-15 seconds – sometimes this triggers a forced boot.
3. If the screen remains black, turn off charging, wait 1 minute and reconnect.

💡 Advice: On Redmi Note models 10/11 and POCO X3/X4 Sometimes it helps to connect to a PC through USB — The system can recognize the device as a media device and supply power.

💡

If the charging indicator flashes red or orange, it is a sign of a battery failure, in which case, turning on without repair is unlikely.

2. use of ADB (Android Debug Bridge) - for advanced users

If your Xiaomi has previously enabled USB debugging, you can enable it via your computer using ADB. This method works even with a fully discharged battery (if the phone is recognized by the PC).

🔧 What's the matter:

• 🖥️ Computer with installed ADB and Fastboot.
• 🔌 Original. USB-cable (better than the one that came with the kit).
• 📱 Included debugging by USB (Settings → The phone. → Assembly number (7 taps) → For developers → Debugging by USB).

📌 Step-by-step instruction:

1. Connect Xiaomi to the PC.
2. Open the command prompt (Win + R → cmd) and type: adb devices If the device is identified (the serial number appears), move to the next step. If not, try another cable or USB port.
3. Enter the command to turn on: adb shell input keyevent 26 (this is an emulation of the power button press).
4. If it doesn’t work, try the alternative command: adb shell am start. -a android.intent.action.BOOT_COMPLETED

⚠️ Attention: On some firmware MIUI (especially in the global versions) USB It turns off after you restart. If you didn't turn it on before, this method won't help.

3. Launch through Recovery Mode (Recovery Mode)

If Xiaomi doesn’t turn on but is responsive to charging (e.g., the indicator is on), you can try logging into Recovery Mode and starting a reboot from there.This method works on most models, including the Redmi 9/10, POCO F3 and Xiaomi 11T.

🔄 How to log in to Recovery:

1. Turn off the phone from charging.
2. Press the volume button + power button for 10-15 seconds.
3. If the screen remains black, try the volume button + power combination.
4. On some models (for example, Redmi Note 8 Pro) you need to hold both volume buttons. + feeding.

📱 Further action:

• 🔧 If you have a Recovery menu, select Reboot. → Reboot to System (control – volume buttons, confirmation – power button).
• 🔄 If the phone is stuck on the logo MI, wait 5-10 minutes – sometimes the system is slow to load.
• ⚠️ If Recovery offers to reset the settings (Wipe Data), do not agree if you did not make a backup!

💡 Secret trick: On some firmware MIUI You can turn on your phone if you select Mount in Recovery. → Enable MTP, Then connect it to a PC. Then try sending the adb reboot command.

4.Service codes and engineering menus – hidden features of Xiaomi

Few people know, but Xiaomi has hidden service codes that can help turn on a phone without a power button, which only work if the device is at least partially responsive to the charging connection (for example, the indicator vibrates or lights up).

📞 List of working codes:

🔍 How to use codes:

1. Connect Xiaomi to charging and wait 5-10 minutes.
2. Dial the code on the emergency call keyboard (if the screen is turned on but the phone is not loading).
3. If the code worked, try the Restart or Power Off option in the engineering menu (sometimes it is available even without the full system boot).

⚠️ Please do not enter codes at random – some of them (##7780##, *2767*3855#) They can reset or erase data!

5. Disassembly of the phone and closure of contacts is an extreme measure

If software methods don't work, then there's a physical intervention -- disassembling the case and simulating the power button by closing the contacts -- that's only suitable for users with experience in electronics repair.

🛠️ What's the matter:

• 🔧 Set of screwdrivers (Xiaomi uses cruciform screws) PH00 and Y00).
• 🧲 Plastic blade or mediator for opening the body.
• 🔌 Tweezers or needles for closing contacts.
• 📸 Camera (to photograph the location of the parts before disassembly).

⚙️ Step-by-step process:

1. Turn off the phone (if it is still responding) and remove it. SIM-map.
2. Heat the back cover with a hairdryer (temperature ~60°C) - this will soften the glue.
3. Carefully tuck the lid with a plastic spatula, starting at the bottom edge.
4. Unscrew all the screws that hold the metal plate above the battery.
5. Find the contacts of the power button (usually signed as PWR_KEY or POWER_SW).
6. Close the contacts briefly with tweezers (as if you pressed a button).

📌 Where to find contacts:

• On the Redmi Note series - next to the plug for the button plume.
• On the POCO F - under a metal plate above the battery.
• On Xiaomi Mi 11/12 – near the charging connector (you need to remove the middle screen plume).

⚠️ Critical: Don't close contacts for longer than 2 seconds, it can burn the power controller.

💡

If your Xiaomi is guaranteed, try the official service center first.

6. Connecting to charge with button retention - an unobvious life hack

One of the little-known ways is to combine charging connectivity with volume button retention, which works for many Xiaomis because the system recognizes this as an alarm to turn on.

🔌 Instructions:

1. Connect the phone to the charger.
2. Hold the volume button for 20-30 seconds.
3. If nothing happens, try holding both volume buttons at the same time.
4. On some models (Redmi 9A, POCO M3) helps to hold the volume button + charge connection.

🤔 Why does it work?

The fact is that on Xiaomi, the volume buttons are connected to the same controller as the power button. Prolonged retention can initiate forced booting, especially if the battery is slightly charged.

⚠️ Note: Do not hold the buttons longer than 40 seconds – this can lead to a hard reset (data loss) on some firmware.

7. Contacting a service center - when nothing helps

If all of these methods fail, only professional repairs are left, and in these cases, you should bring Xiaomi to the service:

🔧 Signs of malfunction requiring repair:

• 💥 The phone fell into the water or was heavily hit.
• 🔋 The battery swelled (seems to be on the raised back cover).
• 📵 None of the methods gives any reaction (no vibration, indicator, heating).
• 🔌 The power button "fails" or does not return to the original position.

💰 Cost of repairs in 2026 (example prices):

🔍 How to choose a service:

• 🏢 Official Xiaomi service centers (list on the site mi.com) – warranty for repair, but more expensive.
• 🛠️ Local workshops are cheaper, but check reviews and ask for a guarantee.
• 📦 If the phone is warranty – repairs by the power button are usually covered (except for mechanical damage).

⚠️ Note: Before the repair is required:

1. Make sure that your phone doesn’t have any important data (or it’s stored).
2. Remove all passwords and fingerprints – some services require unlocking.
3. Check if there's any left on the phone. SIM-memory-card.
