How to launch a Xiaomi smartphone without a working power button: all ways from charging to soldering iron

A broken power button on Xiaomi is one of the most frustrating breakdowns that can completely paralyze a device. Without the ability to physically press the power button, many users think the smartphone has turned into a brick. However, there are at least 5 proven ways to run a Redmi, POCO or Mi without a working power button - from simple charging manipulations to deep interference with the hardware.

In this article, we will look at all the methods, from the safest (suitable even for beginners) to the extreme (requires a soldering iron and repair skills), you will learn how to do without the power button temporarily or permanently, what tools will be needed, and what to do if the smartphone went to the bootloop after a failed launch attempt. Importantly, some methods can lead to data loss or exacerbate the problem, we honestly warn about the risks in each section.

Before you start, check if the problem is really in the button: connect Xiaomi to charge for 30-60 minutes. If the charging indicator is on, but the screen does not respond to the hold of the button, it is likely the on mechanism that is to blame. If the indicator does not light up at all, the problem may be in the battery, the plume or the motherboard.

1. Starting through the charger (the "hot reboot" method)

The easiest and safest way to do this is to use 60 to 70 percent of Xiaomi models (especially on the Redmi and POCO budget series) to simulate the power button pressing through power manipulation, and you only need an original (or quality) USB-Type-C charger.

Instructions:

• 🔌 Connect your smartphone to charge and leave it for 10-15 minutes (even if the battery is charged.
• ⏱️ After 15 minutes, disconnect the cable from the smartphone, wait 3-5 seconds and connect again.
• 🔄 Repeat the disconnect / connection 3-5 times in a row at intervals of 2-3 seconds. On some models (for example, Redmi Note 8 Pro), the smartphone turns on after 3-4 cycles.
• 📱 If the Mi logo appears on the screen, hold the volume button to log into Fastboot (then you can log in via the command).

Why does it work? When you have a sudden power outage, the battery controller of some Xiaomi models interprets this as a signal to turn on. The method doesn't guarantee 100% results, but it's absolutely safe -- even if it doesn't work, you won't lose anything.

⚠️ Warning: Do not use cheap chargers with unstable voltage. Current surges can damage the power controller, especially on models with Quick Charge 3.0/4.0.

Try another charger (original)

Make sure the cable is not damaged

2.Use of ADB-teams (if) USB-debugging was included)

If your Xiaomi has been activated before USB-debugging (in the developer settings), you can enable it through your computer using ADB (Android Debug Bridge – This method is suitable for advanced users and requires pre-configuration.

What you need:

• 🖥️ A computer with installed Xiaomi drivers and ADB (You can download from the official Android website).
• 🔌 USB-Type-C Cable (preferably original).
• 📱 Smartphone that at least once connected to this PC in debugging mode.

Step-by-step:

1. Connect the switched off smartphone to the computer.
2. Open the command line (Win + R → enter cmd) and execute the command: adb devices If the device appears in the list, move to the next step. If not, try reconnecting the cable or installing the drivers again.
3. Enter the command to simulate the power button: adb shell input keyevent 26 (code 26 corresponds to the power button in Android).
4. If the smartphone doesn’t respond, try an alternative command: adb shell reboot It will force the device to restart.

If ADB doesn’t see the device, but you’re sure the debugging has been enabled, try holding the volume button when connecting to a PC — sometimes it helps to “wake up” the smartphone in Fastboot mode.

⚠️ Attention: Adb reboot bootloader or fastboot reboot commands can loop your smartphone in Fastboot mode if the power button doesn't work.

3. Enter Fastboot Mode and Launch via MiFlash

If the smartphone reacts to the connection to the PC (for example, the indicator vibrates or lights up), but does not turn on, you can try to log into the Fastboot and run it through the MiFlash Tool.

Instructions:

• 🔌 Connect the switched off smartphone to the computer.
• 🖱️ Press the volume button for 10-15 seconds (POCO F1, Mi 9) this is forced to activate Fastboot.
• 📥 Download and install the MiFlash Tool (the official tool from Xiaomi for firmware).
• 🔧 In the program, click Refresh – if the device is determined, select it in the list.
• 🔄 Press Reboot. → If the button is inactive, try the command manually: fastboot reboot.

If the smartphone has successfully booted, but the power button still does not work, we recommend to turn on immediately. USB-debugging and unlocking OEM It's in the developer settings, and it makes it easier to manipulate things.

💡

If your smartphone has booted into Fastboot but doesn’t log in, try flashing only the boot partition through MiFlash without clearing the data, which sometimes solves the loop problem.

4. Hardware method: Testpoint closure (for experienced)

If the software doesn't work, it's a direct interference, and Xiaomi's motherboard has test points that mimic the power button, which requires the dismantling of the smartphone and minimal skills with a soldering iron or tweezers.

⚠️ Warning: Incorrectly closing contacts can lead to short circuit, damage to the motherboard or loss of data. If you are not sure about your skills, you should contact the service center.

How to find test points:

• 🔍 Disassemble your smartphone (instructions for your model can be found on YouTube for “model disassembly»).
• 📍 Look for the inscriptions on the motherboard. PWR_KEY, KPP or ON_OFF. It's usually a pair of contacts next to the battery connector.
• 🔧 Close the contacts carefully with tweezers or screwdriver for 1-2 seconds. If the smartphone vibrates or the screen lights up, the contacts are found correctly.

To solve the problem, you can solder wires to test points and bring them out (for example, through a hole in the case) to turn on the smartphone in the future, closing the wires. This is a temporary “crut” but it will allow you to use the device before changing the button.

💡

Closing the testpoints is the only way to turn Xiaomi on with a completely dead power button if the software methods don’t work.

5. Alternative methods: wireless charging and external batteries

If your Xiaomi supports wireless charging (e.g. Mi 11/12/13, POCO F4 GT), you can try turning it on via a Qi station. Sometimes abrupt interruption of wireless charging (de-station and back) simulates pressing the power button.

Another option is to use an external battery with a boot function (for example, Xiaomi Power Bank 3 Pro), some models, when connected to such a power bank, automatically signal to turn on.

1. Connect your smartphone to the power bank turned off.
2. Enable Boost mode on powerbank (if any).
3. Turn off the cable for 5 seconds and plug it back in.

These techniques rarely work, but they can help if other methods are not available, and the main advantage is that you don't need to disassemble and the risk of damage is minimal.

6. When nothing helps: diagnosis and repair

If none of the methods worked, the problem could be more serious than just a faulty power button.

• 🔋 Faulty battery – if the battery is swollen or does not hold charge, the smartphone may not turn on even with the working button.
• 🔌 Damaged plume of power buttons – often occurs after falls or moisture.
• 🖥️ Firmware failure – if the smartphone went to “bootloop”, you will need to flash through EDL-regime.
• ⚡ Problems with the power controller – in this case, the smartphone will not respond even to charging.

For an accurate diagnosis, contact the service center.

⚠️ Warning: If the smartphone was in water or fell from a height, do not try to turn it on yourself - this can lead to a short circuit.
