The power button on Xiaomi’s smartphone is one of the most vulnerable design elements. Despite its apparent simplicity, its failure can completely paralyze the device: the phone does not turn on, turn off, reboot, and sometimes does not respond to charging. Owners of Redmi, POCO and flagship Xiaomi 13/14 series face this problem more often than it seems, according to service centers, the share of power button malfunctions accounts for up to 12% of all mechanical damage calls.
The cost of repairs varies from 500 to 4 500 rubles depending on the model, type of breakdown and place of circulation. But before you take the phone to the workshop, it is worthwhile to figure out: is it really the fault of the button? Perhaps the problem lies in the plume, the power chip or even the charging connector. In this article, we will examine in detail the prices for repairs in 2026, typical causes of failure, diagnostic methods and alternative solutions to the problem - from temporary bypass of the malfunction to a complete replacement of the module.

Why the inclusion button on Xiaomi breaks: top-5 cause
The power button in Xiaomi smartphones is not just a mechanical switch, but a complex module that includes a micro-switch, a flexible plume and sometimes even additional sensors (for example, in models with a dual-press function to start the camera).
Here are the most common reasons:
- 💦 Even if the phone is not sinking, condensation or high humidity can oxidize the pins of the buttons. IP53/IP68 (For example, Redmi Note 10 or POCO X3 Pro).
- 🤳 Mechanical damage: Falls on a hard surface, impacts or even a strong press (for example, when the phone is in your pocket and the key is pressed on the button) deform the mechanism.
- ⚡ Wear of the plume. Over time, the flexible plume that connects the button to the motherboard is rubbed or moved away from the connector.
- 🔋 If the button doesn't work, but the phone turns on from charging, it may not be the mechanism that's to blame, but the chip. PMIC (Power Management IC).
- 🛠️ After changing the screen or battery, the master sometimes damages the button plume or forgets to plug it back in.
Interestingly, in Xiaomi 12T and newer models, the power button often fails due to a structural defect: its mounting is weakened, and when pressed frequently, it begins to “backlash”. In the POCO F5, the problem is usually associated with oxidation of the contacts due to poor sealing of the body.
How to check if the switch button is broken
Before you drive your phone to the service, make sure it's the button that's the problem, not the other component. Here are 3 ways to diagnose:
- Check the response to charging. Connect the phone to the charger. If the screen lights up (even without pressing a button), the problem is most likely the mechanism of the button or its plume, if not, it is the power controller or the battery.
- Testing with Recovery Mode. Press Volume up + Power for 10-15 seconds. If the phone loads into the recovery menu, the button is physically healthy, but the firmware will crash.
- Visual inspection. Light a flashlight on a button, and if it's sunk deeper than the adjacent keys, or if it's wobbling, the mechanism is damaged.
If the phone doesn't respond to anything, but it vibrates or warms when connected to a charger, it may indicate a short circuit in the power chain, in which case self-repair is dangerous - it is better to contact the service.
💡
On some models (such as the Xiaomi 11T Pro), the power button is combined with a fingerprint sensor, so if the scanner stopped working with the button, the problem is precisely in the module, not in the plume.
How much does it cost to repair the power button on Xiaomi in 2026: a price comparison
The cost of repair depends on four factors: the model of the phone, the type of breakdown (change of a button, a plume or the entire module), the warranty status and the place of repair (official service, a private workshop or self-repair).
| Xiaomi model | Replacement of the button (rub.) | Replacement of the plume (rub.) | Replacement of the power module (RUB) | Duration of repairs |
|---|---|---|---|---|
| Redmi Note 12/13 | 800–1 200 | 1 000–1 500 | 1 800–2 500 | 1-2 days |
| POCO X5/F5 | 900–1 400 | 1 200–1 800 | 2 000–3 000 | 1-3 days |

Where to fix: official service vs private workshop
The choice of the repair site depends on your priorities: speed, price or reliability. Let's consider the pros and cons of each option.
Official Xiaomi Service Center
- ✅ Warranty for repairs (usually 6 months).
- ✅ Original parts (but not always – sometimes put “certified analogues").
- ✅ Diagnosis is free if you agree to a repair.
- ❌ Expensive by 20-50% compared to private.
- ❌ Long term (from 3 days to 2 weeks).
- ❌ Refusing to repair phones with traces of moisture or self-opening.
Private workshops
- ✅ Cheaper (savings up to 1,000-1,500 rubles).
- ✅ Quick repairs (often while you wait) or during the day).
- ✅ Ready to take on complex cases (for example, after unsuccessful self-repair).
- ❌ The risk of running into unscrupulous masters who will supply low-quality spare parts.
- ❌ The warranty is usually less than (1-3 months) or is absent.
- ❌ There may be no check or contract.
If your Xiaomi is still under warranty, first contact the official service - perhaps the breakdown is recognized as a warranty (for example, if the button failed without mechanical damage). Otherwise, choose a workshop with good reviews and be sure to ask what parts will be used.
💡
Before repairing in a private workshop, ask to show a new button in the package - the original Xiaomi parts have a hologram and a serial number.
Can I fix the switch button myself?
Replacing the power button on Xiaomi is a medium-sized repair.
- 🔧 Set of screwdrivers (star) T3, T4, cross-section).
- 🧲 Screen suction cup.
- 🔥 Hair dryer or glue heating station.
- 📱 New power button (cost – from 200 to 800 rubles on AliExpress).
- 🧴 Alcohol or contact cleaner (if the problem is oxidation).
The hardest part is to gently disconnect the battery plume and the motherboard, and a mistake here can short circuit and cause the phone to break down completely, and if you've never taken your smartphones apart, you'd better not take the risk.
Prepare the workplace (clean surface, good lighting)|Take it off. SIM-memory-card|Discharge the battery to 30-50%|Take a picture of each step of the disassembly|Have tweezers and plastic spatula on hand-->
For the Redmi 9/10 and POCO M3/M4 models, there are detailed guides on YouTube, but with flagships (Xiaomi 13 Ultra, Mix Fold) it is better not to experiment - their design is much more complicated.
⚠️ Warning: If the phone doesn't turn on after you change the button, check if the plume is connected to the motherboard. A common mistake is to confuse the button plume and fingerprint sensor connectors.
Temporary solutions: how to use the phone without the switch on button
If repairs are delayed and the phone is urgent, you can do without a physical power button. Here are 4 working ways:
- Use charging. Connect your phone to the charger - many Xiaomi models turn on automatically when power is applied. To turn off, keep Volume up + Volume down 10-15 seconds (does not work on all firmware).
- Activate the regime ADB. If it's on. USB-debugging, you can send commands from PC: adb shell input keyevent 26 # simulated pressing the power button adb shell reboot # reboot
- Install the Button Remapper app (requires root) which allows you to reassign the power button functions to other keys (e.g., to increase volume).
- Restore via Mi Flash. If the phone does not respond at all, but the PC sees it in Fastboot mode, you can flash the stock firmware through the Mi Flash Tool (instructions are available on 4PDA).
These methods will not replace full-fledged repairs, but will help to "get through" before a visit to the service. POCO X3 frequently ADB-Reboot commands while waiting for a new button with AliExpress.
⚠️ Attention: On models with AMOLED-With screens (such as the Xiaomi 12 Pro) long-term use without turning off can cause the matrix to burn out.
How to avoid breaking the power button in the future
Preventing the wear of the power button is easier than repairing it. Here are 5 practical tips:
- 🛡️ Use a button-protected case. Models with protruding sides (such as the Spigen Tough Armor) reduce the risk of accidental pressing.
- 🚿 Avoid moisture, even if the phone is protected. IP53, Do not place it near water and regularly dry the ports.
- 🔄 Do not press the button unnecessarily. For example, double-tapping (setting in Settings) to lock the screen. → Lock screen).
- 🔋 Don't keep your phone on charge all the time.Overheating can warp the plastic elements of the button.
- 🛠️ Clean the connectors regularly. Dust and dirt accelerate wear and tear. Use compressed air or a soft brush.
If you notice that the button has started to stick or requires a stronger press, do not delay the diagnosis. In the early stages, the problem can be solved by simply cleaning the contacts with alcohol, without replacing the parts.
