How to reboot Xiaomi Power Bank: all the ways and recommendations

Introduction: When you need to reboot Xiaomi Power Bank

Xiaomi Power Bank is a reliable and popular external battery that helps to charge your gadgets on the go. However, like any electronics, they can sometimes crash: do not turn on, do not charge devices or freeze on the display. In most cases, a simple reboot solves the problem, but not all users know how to do it correctly.

In this article, we will discuss all possible ways to reboot Xiaomi Power Bank, including software reset, hardware reset and recovery from critical errors. You will learn how to distinguish between freeze and breakdown, which models support a particular function, and what to do if standard methods do not help.

Signs of failure: when you need to restart

Before you start resetting, it is important to make sure that the problem does require a reset, and here are the main symptoms that indicate the need for a reset:

• 🔋 Charge indicators burn chaoticly or do not match the actual level of the battery.
• 🔌 Power Bank does not respond to the connection of the charger or gadget.
• 🔄 The device turns on, but immediately shuts down or cyclically restarts.
• 📵 The body is overheated, although the battery is not used.
• ⚡ After a fall or hit, the power bank stopped working.

If you see at least one of these signs, a software or hardware reboot is likely to help, but in some cases (such as mechanical damage), repair or replacement of the device may be necessary.

Method 1: Software reboot (soft reset)

The safest method is a soft reboot that doesn’t reset settings but restarts the control controller, which is suitable for most models including Mi Power Bank 3, Mi Power Bank 4 and Redmi Power Bank.

Instructions:

1. Disconnect all devices from Power Bank.
2. Connect the power bank to the charger (preferably original from Xiaomi).
3. Press and hold the power button for 10-15 seconds.
4. Release the button when the indicators go out and light up again.

If the device worked normally after that, the problem was a temporary failure of the controller. If not, move on to the next method.

Method 2: Hardware reset (hard reset)

If the soft reset doesn't work, you'll have to do a hard reboot, which resets all the temporary data of the controller, but doesn't affect battery capacity, and is suitable for models with a reset button (usually hidden under a label or in a small hole).

Step-by-step:

1. Find a small hole on the case with an inscription RESET or RST (most often located near USB-port).
2. Take a paper clip, needle or other thin object.
3. Carefully press and hold the reset button for 5-7 seconds.
4. Release the button and wait until the indicators start flashing in normal mode.

⚠️ Warning: Do not use metal objects with sharp edges - they can damage the body or contacts. If the hole is missing, this method is not suitable for your model.

Method 3: Complete discharge and charging (battery calibration)

Sometimes, Power Bank failures involve mischarging the charge level, which is where full discharge and then 100 percent charging helps, a technique also called "battery calibration."

How to perform calibration:

1. Connect a device (such as a smartphone) to Power Bank and discharge it until the power bank is completely shut down.
2. Leave the Power Bank discharged for 2-3 hours.
3. Connect the original charger and charge to 100% (the indicators should burn smoothly, without blinking).
4. Disconnect from the network and reconnect the load (smartphone, tablet).

This helps to "reset" the controller's current charge level, so if after calibration the problem persists, the battery or control board may have malfunctioned.

💡

If the Power Bank does not discharge to the end (for example, it shuts down by 20%), this may indicate wear of the battery, in which case calibration will not help - you need to replace the battery.

Method 4: Reboot through the application (for smart models)

Some modern Xiaomi models, such as the Mi Smart Power Bank, support management through the proprietary Mi Home app.If your powerbank connects to your smartphone over Bluetooth, you can try rebooting it software.

Instructions:

1. Install the Mi Home app (available for Android and iOS).
2. Connect Power Bank to the application (usually you need to press the button on the case to pair).
3. Go to Devices → Your Power Bank → Settings.
4. Find the Reset or Reset option and confirm the action.

⚠️ Note: Not all models support this feature. If the app does not have a reboot button, use hardware techniques.

What to do if no one method helps

If all of the above methods have not yielded results, the following problems may occur:

• 🔋 Battery wear: Over time, battery capacity decreases and Power Bank can shut down at the slightest load.The solution is to replace the battery (in the service center).
• 🔌 Controller damage: If the control board fails, the power bank will not respond to the reset.Diagnosis required.
• 💧 Moisture: Even if external corrosion is not visible, oxidation of contacts can block the operation of the device.
• ⚡ Short circuit: If Power Bank is warming or smells of smoke, further use is dangerous!

If the indicators are lit randomly after a hardware reset or the device does not turn on at all, this may indicate a critical firmware error of the controller, in which case only flashing in the service center will help.

If the warranty is still valid, contact the official Xiaomi service. Otherwise, look for proven electronics repair shops.

💡

Most Power Bank malfunctions involve a controller or battery. If the reset didn't work, don't try to disassemble the device yourself - it could cause a fire!
