How to turn on the smartphone Xiaomi without a power button: all working methods

A broken power button on Xiaomi is one of the most frustrating breakdowns that can completely paralyze a device. You can't turn on your phone, reboot it, or even get out of sleep. But don't rush to bring it to the service center: 80 percent of the time, you can launch your smartphone without physically pressing a button. In this article, we'll look at 5 proven ways that work on models from the Redmi Note 10 Pro to the Xiaomi 13 Ultra, and also tell you how to avoid repeated problems.

It is important to understand that the methods differ in complexity: from elementary connection to charging to use. ADB-We'll start with the simplest solutions and gradually move on to the advanced ones. If your Xiaomi is dead to zero, try the methods in the first section first, which often save even in the most hopeless cases.

We warn you beforehand that some methods require an unlocked bootloader or root rights. If you've never done firmware, you'd better focus on mechanical methods (charging, OTG) or consult a specialist. Now we're going to practice.

Method 1: Enable via charger (works on 90% of models)

The easiest and safest method is to use an original charger with either a Type-C or Micro-USB cable (depending on the model), which works if:

• 🔋 The battery is not completely discharged (remainder of the charge) ≥5%).
• 📱 The phone was not turned off forcibly (for example, via adb reboot).
• ⚡ The charger gives out ≥18 W (fast charging).

Connect Xiaomi to charge and wait 10-15 minutes. Most models (Redmi 9A, Poco X3, Mi 11) will display a battery indicator (red light bulb or Mi logo) when the minimum charge level is reached.

1. Turn off the cable from the phone.
2. Connect it again - sometimes it simulates the pressing of the power button.
3. If the screen catches fire but the phone doesn’t load, hold the volume button for 10-15 seconds (this can trigger Fastboot).

⚠️ Warning: Do not use cheap chargers without certification, they can damage the power controller, which will lead to complete inoperability of the phone even after repair of the button.

If the method doesn't work, move on to the next one, but first check:

Try another charger (original)

Wipe the phone connector with alcohol from oxidation

Connect to your PC via USB – sometimes it triggers charging

Leave on charging ≥30 minutes (if the battery is completely discharged)

Method 2: Use of the OTG-cable (for models with support) OTG)

If your Xiaomi supports OTG (On-The-Go), you can simulate the power button press with a mouse or keyboard.This method works on most modern devices (Redmi Note 12, Xiaomi 12T, Poco F4), but requires:

• 🖱️ OTG-adapter (or Type-C cable) → USB-A).
• 🔌 Mouse with USB-wiring (wired or wireless with a connection) USB-receiver).
• 🔋 Minimum battery charge (≥10%).

Instructions:

1. Connect. OTG-Adapter to the phone and adapter to the mouse.
2. If the screen catches fire, move the cursor – this will unlock the phone from sleep mode.
3. If the phone is turned off, the mouse connection can automatically turn it on (on some models).
4. If nothing happens, try plugging in the keyboard and pressing Enter or Space.

In the models with MIUI 13+ This method works in 60% of cases, because the system recognizes the problem. OTG-If the mouse didn't help, try the combination with charging:

1. Connect the phone to the charger.
2. In 5 minutes, plug in. OTG-mouse.
3. Press any mouse button or move the cursor.

Method 3: Enable via ADB (for advanced users)

If your Xiaomi has enabled debugging on USB (Settings → The phone. → Version. MIUI → 7 times to unlock the developer options, you can turn it on through ADB-This method works even if the phone is completely off, but requires:

• 💻 Computer with drivers installed ADB and platform-tools.
• 🔌 USB-cable (preferably original).
• 🔧 Included debugging by USB button-break.

Instructions:

1. Connect your phone to your PC via USB.
2. Open the command line (Win + R → enter cmd).
3. Enter the command to check the connection: adb devices If the phone is identified (a serial number appears), move to the next step. If not, try another command: fastboot devices
4. To turn on the phone, use: adb shell input keyevent 26 (where 26 is the code of the power button in Android).
5. If your phone is in Fastboot mode, use: fastboot reboot

⚠️ Attention: Teams ADB They do not work if the debugging is USB If you've never connected your phone to a PC to debug, it's useless.

If ADB does not define the device, try:

• 🔄 Reconnect the cable to another USB-port (preferably) USB 2.0).
• 🔧 Install Xiaomi drivers manually through Device Manager.
• 📱 Hold the volume button when connecting (sometimes this puts the phone in Fastboot mode).

Method 4: Removal and Reverse Battery Installation (for Maintenance Models)

If your Xiaomi is a removable battery (Redmi 4A, Redmi 5A, Mi A1) or you are ready to disassemble the case, you can try forced power reset. This method works 100% of the time, but you need to be careful:

Instructions for removable batteries:

1. Turn off your phone (if it is not already turned off).
2. Remove the back cover (on older models it is fastened with latches).
3. Remove the battery for 10-15 seconds.
4. Install it back and try to turn on the phone.

For models with a non-removable battery (Redmi Note 11, Xiaomi 12, Poco X5), the process is more complicated:

1. You will need a plastic spatula and a hair dryer (to soften the glue).
2. Plug off the back cover, starting from the corners (caution - you can damage the plumes!).
3. Disconnect the battery plume from the motherboard for 20-30 seconds.
4. Connect the plume back and try to turn on the phone.

⚠️ Warning: Disassembling the phone is not warranty (if it is still valid). IP53/IP68 (Xiaomi 13 Pro, Redmi Note 12 Pro+) after dismantling, leakage is broken, which can lead to corrosion of the board when moisture enters.

💡

Before disassembling, take a picture of all the plumes and screws. Use a magnetic screwdriver to keep the details from getting lost. If you're not sure about yourself, you better contact the service.

Method 5: Use of service codes and engineering menus

On some Xiaomi models, you can turn on your phone through service codes or an engineering menu, even if the power button doesn't work.

• 📞 The phone is not completely off (the screen is black but responds to charging).
• 🔢 You know. PIN-code or pattern lock (if the screen is locked).
• 📱 The model supports service commands (e.g. Redmi). 6/7/8, Mi 9/10).

Try the following combinations:

• 📞 Dial from another phone to your number – sometimes this unlocks the screen.
• 🔢 Enter the service code for the reboot: ##7780### (not working on all models).
• 📱 Connect your phone to your PC and try sending a reboot command via Mi. PC Suite.

If the phone is in sleep mode (the screen is black but reacts to the charger connection), try:

1. Connect the charger.
2. Press and hold the volume button + volume button 10-15 seconds.
3. If the Fastboot menu appears, select Reboot using volume buttons.

💡

Service codes only work on phones with an unlocked bootloader or official firmware, and on custom firmware (like LineageOS), these commands may not work.

What do you do if nothing helps?

If none of these methods work, you have three options:

1. 🔧 Repair of the power button in the service center.The cost: from 800 to 2500 rubles (depending on the model).
2. 📱 Replacement of motherboard (if the problem is the power controller) Cost: 50-80% of the phone price.
3. ♻️ Sale of parts (if repair is unprofitable).

Before you bring your phone to the service, check:

• 🔌 Charging connector – it may be contaminated or damaged.
• 🔋 Battery – if it swells, the phone may not turn on.
• 📱 Firmware – sometimes the phone does not respond due to a software failure (flashing through Fastboot will help).

If your Xiaomi doesn’t turn on even after you’re connected to a charger, but it warms up, it’s a sign of a short circuit on the board.
