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

A broken power button on Xiaomi Redmi is one of the most frustrating breakdowns that can completely paralyze a smartphone. Without the ability to physically press the power button, many users think the device has become a brick and can only be carried to a service center. However, in 80% of cases, the phone can be turned on without repair using software or hardware workarounds.

In this article, we’ll look at all the current ways to run Redmi (including the Note 10/11/12, Redmi 9/10/13C, and others) without a power button, from the simplest methods with a charger to advanced techniques through ADB, testpoint, and even circuit circuiting on the board, each method is accompanied by step-by-step instructions, risk warnings, and tips on how to avoid repeated problems.

Important: If your Xiaomi is discharged to 0%, first charge it to at least 10-15% by any of the methods described below. On models with a Snapdragon processor (for example, the Redmi Note 10 Pro), the chance of successfully turning on through charging is higher than on devices with MediaTek (Redmi 9A), which often require ADB or disassembly.

1. Energizing through the charger (the method for a discharged telephone)

The easiest and safest method is to use an original or quality Quick Charge charger, which works if the battery is completely drained and the phone does not respond to the cable connection.

Algorithm of action:

• 🔌 Connect Xiaomi Redmi to the charger (preferably with power) 18W higher).
• ⏳ Leave the phone on charge for at least 20-30 minutes. On some models (such as the Redmi Note 8 Pro) it can take up to 1 hour.
• 📱 If the charge indicator (battery or percentage) appears on the screen, then the phone has already woken up in the background.
• 🔘 Try: Connect and turn off the cable several times (sometimes this simulates the press of a button). Press and hold the volume button + I'll put the charger on if you have one. OTG-cable, connect the mouse – the movement of the cursor can wake the screen.

⚠️ Warning: If the phone shows no signs of charging (not warming, no indication), the problem may be in the power controller or battery. ADB or.

2. Use of ADB (for phones with USB debugging enabled)

If your Redmi has previously activated USB debugging (in the developer settings), you can turn it on via your computer using the Android Debug Bridge (ADB), which works even with a fully discharged battery if the phone responds even slightly to the connection to the PC.

What you need:

• 🖥️ Computer with Windows/Linux/macOS.
• 🔌 Cable USB (preferably original).
• 🛠️ Installed Xiaomi drivers and package ADB Tools (you can download from the official Android website).

Instructions:

1. Connect the Redmi switched off to your computer.
2. Open the command line (Windows) or the terminal (Linux/macOS).
3. Enter a command to check if your PC sees your phone: adb devices If the device appears in the list (even as unauthorized), move on to the next step.
4. Execute the command to simulate the power button: adb shell input keyevent 26 (Code 26 corresponds to the power button in Android.)
5. If your phone doesn’t respond, try an alternative command: adb reboot.

⚠️ Note: If Adb devices don’t show your Redmi, then debugging is a good idea. USB It wasn't on beforehand, and it won't work. In this case, move on to the testpoint or disassembly method.

3. Including through Test Point – for advanced users

Testpoint is a method that works if other methods don't work and you don't want to disassemble your phone. Testpoint is a special pin on the motherboard, the circuit of which forcibly triggers the device in firmware mode (EDL), from there you can "push" the phone into normal operation.

Pre-launch warnings:

• ⚡ The risk of damage to the fee with a neat circuit.
• 🔧 Partial disassembly (removal of the back cover) is required).
• 📱 It doesn’t work on some new models (e.g. Redmi Note 12 Pro).+ Protected against unauthorized access).

Step-by-step:

1. Turn off your phone (if it’s in a black screen state, just make sure it doesn’t warm up).
2. Remove the back cover (on most Redmis it is held on clips; Redmi Note 11 Pro may need a hair dryer to soften the glue).
3. Find a testpoint on the motherboard. It's usually two contacts with a sign. TP, TEST Or circled in red/yellow circles. For popular models: Testpoint location 10/10 Near the battery connector, two contacts under the inscription TP📷 [Scheme](https://example.com/redmi_note10_tp) Redmi 9/9A/9CUnder the top of the board, next to the camera📷 [Scheme](https://example.com/redmi9_tp) POCO X3/X3 Pro Left of the charging connector, contacts in the red circle📷 [Scheme](https://example.com/poco_x3_tp)
4. Close the contacts of the testpoint with tweezers or a screwdriver for 5-10 seconds.
5. Connect your phone to your PC via USB. It should be defined as Qualcomm HS-USB QDLoader 9008 (for Snapdragon) or MTK Preloader (for MediaTek).
6. Use the Mi Flash Tool (for Snapdragon) or SP Flash Tool (for MediaTek) to "push" your phone out of the box EDL-routine.

💡 Useful tip: If after closing the testpoint the phone is not determined on the PC, try using another USB-Some Redmi models require a circuit to be held for up to 30 seconds.

Temporary connection of the power button (for users with soldering iron)

If you're ready to disassemble the phone, the most reliable way is to temporarily plug the power button directly into the board, which will not only turn the device on, but also check if the problem is in the button itself or in the plume.

Tools:

• 🔧 Set of screwdrivers (star, cross).
• 🔥 A slender iron with a thin sting (power to the 30W).
• 🧲 Solder and flux.
• 🔍 Loupe or magnifying glass.

How to proceed:

1. Turn off the phone and remove the back cover.
2. Disconnect the battery (disconnect the battery plume).
3. Find the contacts of the power button on the board. This is usually 4-6 rations next to the plug for the button plume (see photo for your model).
4. Close your contacts. PWR_KEY (or POWER) and GND (land 1–2 So you can use a soldering iron or tweezers in a second, and that simulates the push of a button.
5. Connect the battery and try to turn on the phone.

⚠️ Warning: Do not close contacts for longer than 3 seconds - it can burn the button controller! If you are not sure about your soldering skills, you better contact the service.

💡

Closing the contacts of the power button on the board is the most reliable way to turn the phone on, but it requires care. If the phone turns on after soldering, the problem is precisely the mechanical button or its plume.

5. Use of wireless charging (for supported models)

Some Xiaomi Redmi models (e.g. Redmi Note 10 Pro, Redmi K50) support wireless charging, and if you have one, you can try to turn it on via the Qi station:

Instructions:

• 🔋 Place your phone on a wireless charging (make sure it gives you at least a few extras). 5W).
• ⏳ Wait 10-15 minutes. Some phones start charging even when they're off.
• 🔄 If the charge indicator appears on the screen, try: Connect wired charging (sometimes this starts the phone). Press the volume button + I'll put the charger on. NFC-tag (if the phone supports the phone) NFC).

💡 If wireless charging doesn’t work, try putting your phone at the station at a different angle – sometimes a 1-2mm shift helps.

6. Alternative methods: voice assistant and smart watches

On phones with MIUI 12 and later, you can turn on the screen via Xiao AI voice assistant or a connected Mi Band/smartwatch, which works if:

• 🔋 The phone is not completely discharged (at least 5% charge).
• 📶 Bluetooth or Wi-Fi enabled (to communicate with the clock).
• 🎤 Voice Assistant is activated (in Google Assistant or Xiao settings) AI).

How to try it:

1. If the phone is connected to the Mi Band: Press the button on the bracelet — sometimes it wakes up the screen. Try calling a notification (for example, call the phone from another device).

• Say loudly, “OK Google, turn on the screen,” or “Xiao AI, wake up the phone.”
• Try other commands: "Open the camera", "Show the time".

⚠️ Warning: Do not turn off your phone while you are firmware! this can cause a complete loss of performance.
