You pressed the power button on your Xiaomi Redmi Note 12 or POCO X5 Pro, but it doesn't return to its original position, and the phone is latent or not turning on at all? This problem is common on both new and old models of the brand, from the budget Redmi A2 to the flagship Xiaomi 14 Ultra. The reasons can be different from banal contamination of the mechanism to serious hardware malfunctions.
In this article, we'll look at all the possible scenarios for why the power button sticks, and give you step-by-step instructions for each case, from simple cleaning to flashing through Fastboot. You'll learn when you can do it yourself and when to contact the service center to avoid aggravating the breakdown.
Important: some methods require disassembling the device or working with system files. If you are not sure of your skills, it is better to entrust the repair to professionals - especially for models with a high-quality system. IP-certification (e.g., Xiaomi) 13T Pro) where improper assembly may disrupt dust protection.
Why the switch button sticks: 5 main reasons
The power button problem rarely occurs by itself, usually preceded by certain events, and here are the most common reasons Xiaomi owners face:
- π§Ή Contamination of the mechanism: dust, dirt or liquid hit the button, blocking its movement, especially for devices without protection by standard IP53/IP68.
- π Wear of contacts: over time, the metal βpetalsβ under the button become oxidized or deformed, leading to unstable operation.
- π₯ Mechanical damage: phone drop, press hard or attempt to disassemble the case without specialized tools.
- π¦ Software failure: firmware errors (especially after updates) MIUI) They can cause a βhangβ of the press processing.
- π Battery problems: Bloated battery presses on motherboard, shifting components and blocking button.
To determine the cause, pay attention to the behavior of the phone:
- If the button does not physically return to its original position, the problem is mechanical.
- If the button is pushed back, but the phone does not respond, a software failure or damage to the plume is possible.
- If sticking occurs periodically (for example, after overheating) - wear of contacts or battery is to blame.
First Aid: What to Do If the Button is Stuck Right Now
If the power button stops working suddenly, try these emergency measures before disassembling your phone:
- Press the Volume button up + Power button for 10-15 seconds. Some models (e.g. POCO F5) have Volume down + Power combination. If the phone vibrates and reboots, the problem is temporary (possibly system freeze).
- Use alternative buttons Connect your phone to charge β some models (Redmi Note 11 Pro+ and later) turn on automatically when power is applied. Also try double tapping the screen (if Double Tap to Wake is activated in the settings).
- Clean the button without disassembling Take a can of compressed air (for example, to clean the keyboard) and short pulses blow the area around the button. Keep the balloon vertically to avoid liquid. After that, press the button several times - sometimes this helps remove small particles of dust.
If none of the methods worked, move on to a deeper diagnosis.

Do not use cotton swabs or toothpicks to clean the button β they can damage the mechanism or leave fibers inside the case.
Software Solutions: When the Problem Is Not Mechanics
In 20 to 30 percent of cases, sticking a button is due to MIUI firmware failures or system process conflicts.
1. Reset settings via Recovery
If the phone turns on but the power button is not working properly (for example, it is delayed), reset to factory settings:
- Turn off the device (forced if necessary).
- Press Volume Up + Power before the Mi logo appears.
- In the Recovery menu, select Wipe Data β Wipe All Data (manage by volume buttons, confirm by power button).
- After reset, check the button.
2. Update or roll back firmware
If the problem has occurred after the MIUI update, try:
- π₯ Update to the latest version: Go to Settings β The phone. β Updating the system.
- π Reverse to old firmware (if the update caused a failure): this will require unlocking the bootloader and flashing the device through Fastboot using the Mi Flash Tool.

3. Verification for viruses and conflicting applications
It is rare, but it happens that third-party applications (especially those with ADMIN rights) block click processing.
- When you turn on your phone, press the Volume down until the Safe Mode label appears.
- Remove recently installed programs.
- Reset the device.
Critical point: if after resetting or updating the button still does not work, the problem is precisely hardware - move to mechanical repair methods.
Mechanical cleaning of the button: step-by-step instructions
If the button doesn't physically press or comes back with difficulty, it needs to be cleared.
- π§ Setting screwdrivers PH00 and T3/T5 (Xiaomi is usually used for T3).
- π§² Plastic blade or mediator for disengaging the body.
- π§΄ Isopropyl alcohol (90%+) and cotton-stick.
- π₯ Fryer (optional, for drying).

Step-by-step process:
- Removing the back cover: Heat the edge of the screen with a hair dryer (not above 60Β°C) to soften the glue. Carefully apply the lid with a plastic blade starting at the bottom edge. Be careful - on the Xiaomi 12T and newer, the fingerprint scanner plume runs under the lid!
- Unplug the screws holding the battery's metal plate, and unplug the battery connector with a spatula. Don't pull the wires!
- The power button is located on the motherboard under a small metal cover, and carefully remove it and inspect the mechanism.
- Clean and repair Wet cotton swab in isopropyl alcohol and clean the contacts of the button. If you see damage to the petals, they can be gently bent with tweezers. If you wear it hard, you have to replace the button.
After assembly, check the button, and if the problem persists, it may be that the plume or the board itself is damaged.

On IP-certified models (such as Xiaomi 13 Pro) after disassembly, leakage is broken. To restore protection, you will need to replace the adhesive layer and check the seals.
Replace the power button: When cleaning doesn't help
If the button mechanism is broken or the contacts are completely erased, you will need to replace. For Xiaomi, the power buttons are sold as a separate module (for example, the Power Button Flex Cable for the Redmi Note 10 Pro). The average cost of a part is 300-800 rubles depending on the model.
How to choose the right button:
| Model phone | Articular of the button | Notes |
|---|---|---|
| Redmi Note 11/11 Pro | XJT-00124 | Included is a plume with a volume button |
| POCO X3/X3 Pro | MBP-00567 | A soldering iron is required for soldering contacts |
| Mi 11 Lite | XJT-00342 | The button is combined with the frame of the body |
| Redmi 9A/9C | MBP-00211 | Budgetary options are often forged |
Replacement process:
- Take the phone apart (as in the previous section) and remove the old button.
- Make sure to keep your contacts open (if they are soldered) or gently disconnect the plume.
- Install a new button, making sure it fits tightly to the board.
- Put the phone back together.
β οΈ Note: On Xiaomi models with an infrared port (for example, Redmi Note 8 Pro), you can accidentally damage the IR sensor when you change the power button.
Alternative ways to turn on your phone without a power button
If the button is completely out of order and repair is delayed, use these methods to turn on the device:
- π Charging: Connect your phone to the network - some models (POCO X4 Pro, Redmi K50) automatically activated when feeding.
- π± ADB-team (if debugging is enabled) USB): Connect the phone to the PC and perform in ADB: Adb shell input keyevent 26 This simulates pressing the power button.
- π Automatic turn on schedule (if previously configured): check in Settings β Additionally. β Schedule of on/off.
- π€ Voice Assistant: If Google Assistant is activated, say βOK Google, turn on your phoneβ (not all models).
For permanent use without a power button, you can reassign functions to other keys using applications like Button Mapper (root rights are required).
When to contact the service center: signs of serious breakdown
Not all power button problems can be solved by yourself. Contact the service immediately if:
- π₯ The phone overheats when you press a button (possibly a short circuit on the board).
- π₯ The button has completely fallen off or traces of oxidation are visible under it.
- π The battery is swollen (seen by the raised back cover or the increased gap between the screen and the case).
- π΅ The phone does not respond to any manipulations (does not turn on, does not vibrate, is not detected by the PC).
- π§ The board shows traces of corrosion or liquid (even if the phone did not sink - moisture could get through the microphone or speaker).
