How to Reboot Xiaomi Phone If the Power button Doesn’t Work: The Complete Guide

Why Xiaomi’s Power button may fail and what to do about it

The power button on Xiaomi smartphones is one of the most vulnerable elements after the battery. According to service centers, up to 15% of mechanical failures are associated with it. The reasons range from banal wear (especially on Redmi Note 4/5 models, where the button was a weak spot) to moisture or falls. But even if the physical button refuses to work, this is not a sentence for the device. Today’s Xiaomi smartphones support several alternative ways of rebooting, which are not known to all users.

It is important to understand the difference between software failure (when the button does not respond due to the system freeze) and hardware failure (mechanical damage to contacts or chips). In the first case, software methods often help, in the second case, you can not do without repair. This article covers both scenarios: from simple charging tricks to hidden engineering menus that the manufacturer does not advertise. We also discuss what actions can permanently disable the phone if a wrong reboot, and how to avoid this.

Method 1: Forced reboot via charger

The safest and most versatile method, which works on 90% of Xiaomi models (from Redmi 4A to Xiaomi 13 Ultra), is to simulate power outages through a break in the charging chain.

• 🔌 Connect the phone to the original charger (power is at least important) 10W). Using cheap adapters can cause a power controller to fail.
• ⏳ Wait for the charging indicator to appear on the screen (usually) 5-10 If the screen is still black, try another charger.
• 🔄 Once the battery icon appears, turn off the cable and immediately reconnect it. 3-4 consecutively 1 second-second.
• 📱 Most of the devices after 3-4 This flashing charging will automatically reboot your phone. If not, move on to the next method.

This is a way of working with Qualcomm's power controller (used in most Xiaomi smartphones), which, when a chain breaks, the system interprets it as an emergency shutdown and initiates a rebuke. Don't use this method more than 2-3 times in a row, which can cause the USB-C connector to wear out.

⚠️ Attention: On models POCO F1 and Mi 8 with Snapdragon 845 processor this method can cause the logo to freeze MI. You will need to use Fastboot to recover.

Method 2: Use of an engineering menu (for advanced users)

If your Xiaomi still has any response to touch (e.g., unlocked by fingerprint), you can use a hidden engineering menu, which is suitable for models based on MIUI 12 and newer, but requires caution – incorrect settings can lead to resetting to factory.

Instructions:

1. Open the phone app and enter the combination: ##4636##
2. In the menu that appears, select Testing (or Testing on firmware with English).
3. Go to the Power section.
4. Click Reboot Device (Reboot Device).

On some models (Redmi Note 10 Pro, Xiaomi 11T) instead of a full menu, a window with a firmware version will open.

##7594##

⚠️ Note: Do not change other options in the engineering menu unless you understand their purpose. For example, the Band Mode option may disable support. 4G, RF Test - disrupt the operation of the Wi-Fi module.

Method 3: Reboot via ADB (if USB debugging is enabled)

If your Xiaomi has previously activated USB debugging (in the developer settings), you can reboot it with your computer, a technique that requires minimal technical skills, but works even when the power button is completely broken.

What you need:

• 🖥️ Computer with installed Xiaomi drivers (you can download on the official website)
• 🔌 Cable USB-C (preferably original)
• 🛠️ Utility. ADB (It is part of Google’s Platform Tools)

Step-by-step:

1. Connect your phone to your computer. The smartphone screen should show a USB connection notification (if the screen is running).
2. Open the command prompt (cmd) in the folder with ADB.
3. Enter the command to check the connection: adb devices If the device is determined, you will see its serial number.
4. Run the reboot command: adb reboot

If your phone doesn’t respond to adb devices, try typing:

adb kill-server


adb start-server

Then try again.

Method 4: Hardware reset (if the phone doesn't respond fully)

When Xiaomi’s smartphone is not showing signs of life (black screen, no response to charging or touching), the last chance is a hardware reset via a combination of buttons, which works even with a fully discharged battery, but requires precise consistency.

Instructions for most models:

1. Turn off the phone from charging (if it was connected).
2. Press the buttons at the same time: 🔽 Loudness down + Power (for 10 seconds)

On models with a Bixby button (for example, Mi Mix 3), it is used instead of volume.

Hold it until you feel a short vibration (usually 8-12 seconds).

Fastboot

Reboot system now

On some devices (Redmi 9A, POCO M3), the combination may differ:

Volume up + Power (15 seconds)

If nothing happens after holding the buttons, try connecting the charging after the combination has been pinned.

⚠️ Note: On devices with an unlocked bootloader, a hardware reset may result in data loss if a custom recap is not installed. TWRP.

Method 5: Alternative methods for specific cases

If the standard methods didn’t work, there are a few non-obvious tricks that can help:

• 🔋 Discharge to 0%: Sometimes the phone freezes at the level of the power controller. Full discharge (wait until the charging indicator stops burning when the cable is connected) can reset this state.
• 🧲 Magnetic trigger: On models with wireless charging support (Xiaomi Mix) 2S, Mi 11 Ultra) bring a powerful neodymium magnet to the top of the body on 2-3 This simulates the closure of the cover and can wake the device.
• 📡 Wi-Fi network: If your phone is connected to your home network, send a ping request from another device: ping 192.168.1.XX -t (where XX — last-minute IP Sometimes this wakes up the network controller, which in turn initiates a reboot.
• 🔊 Voice Assistant: On devices with Google Assistant, try saying, "OK, Google, reboot your phone." This will only work if voice activation has been configured before.

Critically, the magnet method can damage the compass and Hall sensor on some models, so don't use magnets stronger than 1000 Gauss and bring them to the speakers.

💡

If you have Xiaomi with NFC, try attaching it to a payment terminal (like a store) and sometimes this activates the power module through the contactless payment controller.

What to do if nothing helps: diagnosis and repair

If all of these methods fail, the problem is probably hardware, and here's the algorithm for diagnosing:

1. Charging check: Connect your phone to charge for 30 minutes. If the light doesn't light up, the problem may be the power controller or the battery. Try ringing the cable with a multimeter, often at the base of the connector.
2. Screen test: Connect the phone to the computer. If the PC makes the connection sound USB-It's a black screen, it's a problem with the plume of the display or the backlight. Put a flashlight on the screen at an angle, and sometimes it's there, but it doesn't work.

Diagnostics of the button

• Remove the cover and inspect the button for mechanical damage.
• Carefully press the button with the blunt side of the pencil – sometimes the contacts oxidize and require physical pressing.

The cost of repairing the power button in service centers:

If you decide to repair yourself, consider:

• 🛒 Xiaomi is better off buying buttons in trusted stores (e.g. AliExpress from sellers with a rating above 98.
• 🔧 You'll need a set of screwdrivers to disassemble. T3-T5 and mediator.
• 📹 Before disassembly, find on YouTube a video disassembly of your model specifically - the location of the plumes can be very different.

💡

Self-repairing the power button is only useful if you are confident in your skills, and a failure to solder the plume can disable the motherboard, and then it will cost 70-80% of the cost of a new phone.
