The situation where your Xiaomi, Redmi or POCO smartphone stops responding to the power button is always at the most inopportune moment.The device may be fully charged, but the screen remains black and you can neither unlock the gadget nor even check the notifications. Owners immediately start to panic, wondering about the cost of emergency repairs and the risks of data loss.
The cost of restoring the functionality of the power button on Xiaomi smartphones varies widely and depends on the specific device model, type of damage and the method of solving the problem. In some cases, software configuration is enough, and in others you will need a complex hardware replacement of components on the motherboard. Understanding the nature of the breakdown will help you save time and money when you contact the service center.
In this article, we will take a look at all the possible repair options, the current 2026 rates and ways to temporarily use your phone without a physical button, and you will learn why self-heating or tapping can finally finish off the motherboard, and when it is cheaper to buy a new plume than to call a master.
What the final cost of repair depends on
Price formation in service centers does not happen randomly. Cost is directly affected by the complexity of disassembling the case. Flagship models of the Xiaomi Mi or Xiaomi 13/14/15 series often have glass rear covers and moisture protection, which requires the use of special adhesive frames and careful heating when opening. Budget models Redmi Note or POCO M are easier to disassemble, but can have fragile plastic latches.
The second important factor is the availability of spare parts. If you can buy a plug of a switch at any radio parts store for pennies for popular models, you will have to wait for a piece from China for rare or new devices, and the cost also includes the skill of a master: soldering microscopic contacts on the board costs more than simply replacing the module.
And diagnostics, too. Often the problem is not with the button itself, but with the contact oxidation after moisture or software failures, and professional diagnostics can tell you whether you need to pay for soldering or if you need to reflash it enough.
- 📱 Device model: Flagships are more expensive to repair due to the complexity of the design.
- 🛠️ Type of breakdown: Replacing a plume is cheaper than restoring a power chain on the board.
- 📍 Region and service: Prices in Moscow and St. Petersburg are higher than in regional workshops.
Replacement of the button plume: the most frequent scenario
In the vast majority of cases, the problem is solved by replacing the control plume, which is a module that combines the on button, the volume control and sometimes the headphone jack or vibration motor, and mechanical wear on the contact pads causes the signal to simply not pass to the processor.
The replacement process takes 15 to 40 minutes. The wizard removes the back cover, turns off the battery, twists the protective screens and changes the damaged plume to a new one. It is important to use original components or quality analogues, since cheap Chinese copies can stop working after a month or have a fuzzy button stroke.
☑️ Signs of need for replacement of the plume
The cost of such repairs consists of the price of spare parts and work. For budget Redmi plume can cost 300-500 rubles, while for flagships the price of the part reaches 1500-2000 rubles.
| Category of device | Examples of models | Part price (ruble) | Cost of work (ruble) |
|---|---|---|---|
| Budgetary (Redmi A/C) | Redmi 10A, Redmi 12C | 300 – 600 | 800 – 1200 |
| Middle class (Note/Poco) | Redmi Note 12, Poco X5 | 500 – 900 | 1000 – 1500 |
| Flagships (Mi/Xiaomi) | Xiaomi 13, Mi 11 | 1200 – 2500 | 1500 – 2500 |
| Folding (Fold/Flip) | Xiaomi Mix Fold | 3000 – 5000 | 3000 – 5000 |
⚠️ Attention: If the plug fails to work after the replacement, the problem may be the connector on the motherboard. Do not require the wizard to install the third train in a row - you need a deep diagnosis of the circuit.
Salting of the power chain: complex hardware repair
There are times when replacing the plume doesn't work, which means that the damage is deeper on the motherboard itself, often after a smartphone falls or moisture hits, and then you need a micro spike: you need to restore the tracks or replace the power controller.
This type of work requires a highly skilled engineer and the use of a microscope. The cost of soldering is much higher, because it is jewelry work. Depending on the degree of damage, the price can vary from 2000 to 6000 rubles and more. For older budget models, such repairs may not be economically feasible.
Why is rations so expensive?
Sometimes you need to replace the capacitor or resistor in the button circuit, which is cheaper than changing the chips, but still requires disassembling the device to the board level, and after soldering, you must be tested under load to make sure that the switch is stable.
- 💧 Effects of moisture: Oxidation of contacts requires ultrasound cleaning and soldering of elements.
- 📉 Blows: Microcracks in soldering BGA-components can disrupt the contact buttons.
- 🔥 Overheating: Battery bloating or processor overheating sometimes damages nearby components.
Software methods and break-through
If the physical button is broken and you can't carry the phone right now, there are ways to turn the device on and use it software, which is a temporary solution, but it saves data or waits for a paycheck to be repaired.
A combination of buttons can be used to turn the phone off. On many Xiaomi models, pressing the volume button down (or up) when connecting to the charger can trigger Fastboot or Recovery mode. From the Recovery menu, you can sometimes select the option (Reboot) that will start the system.
💡
Use the Double Tap feature to turn on the screen. Go to Settings → Lock screen → Double tap to turn on / off the screen. This will wake the phone without a power button.
To control a phone that is already on, activate Virtual Buttons, and it adds a floating button to the screen that emulates the physical keys. → Additional settings → Virtual buttons. You can also set up a turn-on and off schedule so that the phone can reboot itself when it freezes.
⚠️ Attention: Don't rely on software methods all the time. If the button closes inside, it can cause constant reboots and battery wear. Use workarounds only as a temporary measure.
Home-based diagnostics
Before you look for a service, you can do a primary diagnostic. Try connecting your phone to your computer. If you hear a USB connection sound, it means that the phone is alive, but the screen or system is not turning on. Try pressing the volume button and plugging in the charging — if there is a vibration, the power button is likely to malfunction.
Check if the button is mechanically stuck. Sometimes the problem is solved by a thorough brush with isopropyl alcohol (only if you are confident in your abilities and have turned off the battery). However, if you get a sweet liquid inside, cleaning the outside will not help - you need to disassemble.
Note the behavior of the charge indicator. If it lights up when you connect the charge, but the phone does not respond to long presses (more than 15-20 seconds), this is a sure sign of hardware failure of the button or plume.
- 🔌 PC test: Connecting to a computer will help you to understand whether the board is alive.
- 🔋 Charging: The reaction of the indicator indicates the serviceability of the power controller.
- 🔊 Sound and vibration: Having sound when connecting charging is a good sign.
Where is better to repair: service or private?
If your Xiaomi is less than a year old and there are no traces of opening or moisture, safely bring it to the official service center, where the repair will be carried out for free or at a discounted price, retaining moisture protection (if any).
If the warranty is over, it makes sense to go to specialized independent workshops. They often make repairs faster and cheaper than official ones. Private craftsmen "at home" may take less money, but the risk of using substandard parts or breaking the assembly technology is higher here.
💡
The official service keeps the seal and warranty, but does it for a long time.A private workshop will fix in 1 hour, but you will lose the moisture protection and official warranty.
When choosing a workshop, be sure to ask about the guarantee for the work. A good master gives a warranty for a replaced plume from 1 to 3 months. If you are denied a warranty or told "how it goes", you should look for another service.
