1.Diagnostics: How to tell if the button is broken, not a firmware problem

Before disassembling the phone, make sure that the malfunction is mechanical. Often, the sticking of the buttons is associated with software failures or contamination of contacts.

  1. Restart your phone in Safe Mode (click the power button) β†’ long tap on "Switch offΒ» β†’ Β«Safe Mode. If the buttons are working properly, the third-party app is to blame.
  2. Connect your phone to your PC and check your response to pressing through ADB: adb shell input keyevent 26 # power button adb shell input keyevent 24 # volume increase adb shell input keyevent 25 # volume decrease If commands are triggered but physical presses are not, the problem is the mechanics.
  3. Check for contact oxidation with a flashlight: light under the button at an angle. A greenish coating or white stains are a sign of corrosion.

If the diagnostics confirmed a mechanical breakdown, proceed to disassembly. Except: Xiaomi Black Shark models - they have buttons integrated into game triggers, and replacing requires a complete disassembly of the case.

⚠️ Attention: On phones with NFC-antenna in the power button (for example, Xiaomi) 12T) After replacement, contactless payment may disappear. Before repair, transfer the card data to another device!

2. Tools and parts: what to buy for replacement

3. Step-by-step instruction: how to disassemble Xiaomi and replace the button

The replacement process varies from model to model, but the overall scheme is the same, as seen in the Redmi Note 10 Pro (similar to most Xiaomi 2020-2023).

Turn off the phone and remove it. SIM-map|Remove the cover and protective film (if any)|Prepare a workplace with good lighting|Charge your phone 30-50% (in case of testing)|Take a picture of the location of the screws before unscrewing-->

Step 1: Removing the back cover

Most Xiaomis have a lid attached to the latches and glue to remove it.

  1. Heat the edges of the body with a hair dryer (60-70Β°C) for 2-3 minutes. This will soften the glue.
  2. Insert a plastic spatula into the gap between the lid and the frame (start with the connector for the SIM-map).
  3. Carefully drive the shoulder blade around the perimeter, snapping the clamps. Don't force it, on Xiaomi. 12/13 The series lid may crack!

Step 2: Shutting off the battery

After removing the lid, first of all turn off the battery, otherwise you risk closing the fee:

  1. Unscrew the screws that fix the metal plate over the battery.
  2. Put a battery plume with a plastic spatula and gently disconnect it from the connector.
  3. You can check the power outage with a multimeter (the voltage between the contacts of the battery should be 0 V).
What to do if the battery plume is glued?
In some models (for example, POCO X3 Pro) The plume is fixed with glue. To disconnect it: 1. Warm the area with a hairdryer (not higher than 80).Β°C). 2. Put the plume on a thin plastic map, swaying from side to side. 3. If the glue doesn't lend itself, drop the isopropyl alcohol under the plume and wait 10 seconds. In no case pull the plume upwards, so you can tear off the contact areas!

Step 3: Replace the button

The power and volume buttons on Xiaomi are usually located on a single flexible plume to replace them:

  1. Unscrew the screws that attach the metal plate over the plume of the buttons.
  2. Disconnect the plume from the motherboard (use a shoulder blade, putting it on the edge).
  3. Carefully remove the old button from the groove in the frame. IP53 It can be further glued - heat the area with a phenome.
  4. Set a new button, make sure it sits tightly in the groove. Press it for 10 to 15 seconds.
  5. Connect the plume back and fix it with screws.

For models with touch buttons (such as the Xiaomi Mix 4), the process is more complicated – you need to replace the entire touch module that is integrated into the display.

The design of the buttons varies depending on the series and year of release, and the key differences for the most common models are the following.

ModelButton typeDifficulty of replacement (1–5)Features
Redmi Note 8/9/10Mechanical (train)2Buttons on the same plume. On the Note 10, screws under the lid of different sizes - don't confuse!

Xiaomi 13/14Touch (in display)5Replacement requires removing the screen and soldering the plumes, not recommended for self-repair.
Black Shark 4/5Mechanical. + play-trigger5The triggers are integrated into the buttons. It requires a complete disassembly of the body.

On the Xiaomi Civi series, the power and volume buttons are often β€œsinked” into the body due to the slim design. When replacing, use buttons with reinforced springs (the description should indicate β€œFor Civi”).

⚠️ Attention: On Redmi 9A/9C power button is combined with IR-If the remote control stops working after the replacement, check the connection of the additional plume under the button!

5. Common Mistakes and How to Avoid Them

Even experienced craftsmen sometimes make mistakes that lead to additional breakdowns.

  • πŸ”§ Misfolded screws. Xiaomi uses screws of different lengths (e.g. 1.5 mm and 2.0 mm). If you screw a long screw into a place for a short one, you can damage the board. Solution: spread the screws in groups or photograph their location.
  • πŸ”₯ Overheating when soldering. When replacing the plumes of the buttons on soldered models (for example, POCO X3 NFC) The soldering iron temperature should not exceed 300Β°C. Solution: Use a temperature-adjusted thermo-air station.
  • πŸ’§ The glue hits the contacts, when the glue is re-sealed. LOCTITE 577 can spread out into plumes. Solution: apply the glue in a thin layer and let it dry for 5 minutes before assembly.
  • ⚑ Forgot to turn off the battery. Short circuits with the battery plugged in can burn the power controller. Solution: Always check the voltage with the multimeter after the plume is turned off.

Another common problem is that the button doesn't fit tightly after you've replaced it.

  • πŸ”Ή Incorrectly installed spring (on some models it falls out when disassembling).
  • πŸ”Ή A deformed groove in the frame (often after falls), in which case the groove should be gently bent with tweezers.
  • πŸ”Ή Unoriginal button with a different move!

πŸ’‘

If the button works once again after the replacement, the problem may not be in the button, but in the oxidized contacts on the motherboard. Clean them with a cotton swab dipped in isopropyl alcohol.

6.Where to buy high-quality buttons for Xiaomi

Part quality is responsible for 80 percent of repair success, and here are the sources that we've tested.

  • πŸ›’ Xiaomi's official service centers, which sell original parts, but prices are 30 to 50 percent higher than the market.
  • 🌍 AliExpress (sellers rated 98%+). Look for "Original Model Name Power Button" and look for the reviews from the photo - fakes often differ in the color of plastic.

The cost of buttons in 2026:

  • πŸ”Ή Power button: 300-800 β‚½ (original, 150-300 β‚½ (analogue).
  • πŸ”Ή Volume buttons (set): 400–1200 β‚½ (original, 200-500 β‚½ (analogue).
  • πŸ”Ή Button plume (for models with separate connection): 600-1500 β‚½.

⚠️ Attention: On Xiaomi 12S The Ultra and 13 Pro buttons come with a framed package and cost between 3,000 and 5,000 times to replace. β‚½, Therefore, it is more appropriate for these models to contact the service.

7 What to do if the replacement does not help

If the button still doesn’t work after replacing, the problem may be deeper:

  1. The motherboard's plume is damaged, and if you're not sloppy, the contacts could detach, so you can look at the board under the magnifying glass, and if the tracks are damaged, you need to ration.
  2. Button controller failure: Some Xiaomi (e.g. Redmi Note 8 Pro) have a chip to handle the pressing. CY8C. If it fails, you will need to replace the chip.
  3. The problem is the firmware. Rarely, but it happens that after an update MIUI Solution: Reverse to the previous version of the software via Fastboot.
  4. Mechanical locking: If the phone fell, a metal screen or plate could shift inside the case, so take the device apart completely and check the location of all the elements.

To diagnose the board, use a multimeter in vertebrae mode:

  1. Connect one probe to the contact of the button on the plume.
  2. The second probe bring to the appropriate point on the motherboard (the contact diagram is in the service manual of your model).
  3. If resistance is going to infinity, the chain is broken.

If you're not sure about your soldering skills, you should go to a wizard. The average cost of repairing a button controller in a service is 1,500-3,00. β‚½.

FAQ: Frequent questions about replacing buttons with Xiaomi

How long does it take to replace the button?
For an experienced master β€” 20–40 If you're doing this for the first time, stock up. 1.5–2 In the case of the diagnosing, disassembling and assembly, the models with IP53/IP68 time-increase 3 hours due to the need for sealing.
When you change the button, it works, but it's late. What's the problem?
Probable causes: πŸ”Ή Unoriginal button with other spring resistance. πŸ”Ή Bad contact plume - check if it sits tightly in the connector. πŸ”Ή Oxidation of contacts on the board (need to be cleaned with alcohol).
Can I use buttons from other Xiaomi models?
Theoretically yes, if they match: πŸ”Ή Size and shape (e.g., buttons from Redmi Note 9 are suitable for Note 9 Pro). πŸ”Ή Type of connection (plate or ration). πŸ”Ή The height of the button (on thin models like Xiaomi 12 Lite it is critical). But it is better to take the part specifically for your model, so you will avoid problems with the hardness of the press or incompatibility of the plume.
What to do if the button plume is removed during disassembly?
If the plume is off the plate: Don't panic -- 80 percent of the time, you can solder it back. Clean the contact areas on the board with alcohol. Use a soldering iron with a thin sting (0.5 mm) and solder with flux. Set the plume with tape until the soldering is completely cooled. If you don't have soldering experience, contact the service. Cost of repair of the plume: 800-1500 β‚½.
