Why Xiaomi Power Bank might need to be reset
Owners of Xiaomi external batteries sooner or later face a situation when the device begins to work incorrectly, this can manifest itself in the form of improper display of charge level, refusal to charge gadgets or even complete inoperability, the reasons for this behavior are many, from software failures of the controller to physical wear of the elements.
Powerbank resets are a procedure that helps to return the device to factory settings by fixing most software problems. It is important to understand that Xiaomi does not always advertise official reset methods, especially for budget models. However, there are versatile and specific methods that work on most devices in the Mi Power Bank, Redmi Power Bank and Xiaomi Mi Ultra Compact line.
In this article, we will discuss all current reset methods, including hardware button reset, USB software reset and battery calibration, and learn how to avoid typical errors that can lead to a final device failure.
What Xiaomi models support resetting
Not all Xiaomi power banks have a reset feature, which is mainly available on models with a built-in control controller and USB-Type C port. Below is a list of devices for which the described methods are applicable:
- π Xiaomi Mi Power Bank 3 (10,000 mAh, 20,000 mAh)
- π Xiaomi Mi Power Bank 4 (10,000 mAh) Quick Charge)
- π Xiaomi Mi Ultra Compact (5000 mAh, 10,000 mAh)
- π Redmi Power Bank (10000 mAh) 20,000 mAh)
- π Xiaomi Mi Wireless Power Bank (Wireless Charging)
Xiaomi Mi Power Bank models 1/2 some OEM-versions (e.g. for the Indian market) may not support reset due to simplified electronics. If your model is not listed, try generic methods, but be prepared for them not to work.
β οΈ Warning: Resetting on devices with lithium polymer batteries older than 3 years may result in their final failure.Pre-proceed with a tester or service center to check battery status before the procedure.
| Model | Type of discharge | Tools required | Time of procedure |
|---|---|---|---|
| Mi Power Bank 3 Pro | Hardware + software | USB-cable, paper clip | 5-10 minutes |
| Redmi Power Bank 20000 | Only hardware. | Paperclip or toothpick | 2-3 minutes |
| Mi Ultra Compact 10000 | Sizing + reset | USB-cable | 15-20 minutes. |
| Mi Wireless Power Bank | Special combination | Two. USB-cable | 10 minutes. |
Preparation for resetting: what to do in advance
Before you start resetting, you need to follow several mandatory steps, which will help to avoid damage to the controller or loss of data on connected devices.
First, you can completely deplete the power bank to zero, and then charge it 100 percent, so you can calibrate the charge controller.
- π USB-cable (preferably original from Xiaomi)
- π₯οΈ Computer or laptop (for software resetting)
- π Paperclip or toothpick (to press a hidden button)
- β‘ Charger (power not less than 18W)
If you are planning a software reset, download the official Mi Flash Tool from Xiaomi or the QC3 Tool for Quick Charge-enabled devices. Also check that your PC has drivers installed to recognize external batteries.
β οΈ Warning: Do not use damaged cables or unoriginal chargers to reset, this may short-circuit and cause the power bank to fail.

Method 1: Hardware reset button (universal method)
This is the easiest and most secure way to do this, and works on most Xiaomi Power Bank models, by pressing a hidden reset button that is usually located next to the top of the phone. USB-port.
Instructions:
- Disconnect the power bank from all devices.
- Take a paper clip or toothpick and gently press the small RESET button (it can be indicated by a dot or RST).
- Hold the button for 10-15 seconds until the lights start flashing or go out.
- Release the button and wait 1-2 minutes.
- Connect the power bank to the charger and wait for full charging.
If there is no reset button (as on some Redmi Power Bank models), try an alternative method: simultaneously press the on button and connect the cable to the power button. USB-Hold the button. 5-7 seconds.

If the reset button doesn't respond, try using a thicker metal object (like an unburdened paper clip) and sometimes the contacts oxidize and the thin toothpick doesn't reach the board.
Method 2: Software reset via USB (for advanced users)
This is a method that works for devices with built-in Quick Charge controller or firmware support, and is more complex, but allows you to reset your firmware-level settings.
You'll need:
- π» Windows computer 10/11
- π USB Type C C Cable (for new models)
- π₯ Utility. QC3 Tool or Mi Flash Tool
Step-by-step:
- Connect the power bank to the computer through USB-cable.
- Run the QC3 Tool utility and select the port to which the device is connected.
- In the utilities menu, find the option of Reset Battery Stats or Factory Reset.
- Press Start and wait until the process is complete (usually takes 3-5 minutes).
- Turn off the power bank and complete the full charge/discharge cycle.
On Xiaomi Mi Power Bank 4 models with Quick Charge 3.0 support, the QC3 Tool reset also allows you to reset the charging cycle counter, which can extend the battery life by 10-15%.
β οΈ Attention: Continuous use of reset utilities may result in the controller being blocked.It is recommended to perform this procedure no more than 1 time in 6 months.
What if your computer doesnβt see the Power Bank?
Method 3: Calibration of the battery (alternative to reset)
If hardware and software resets don't work, try battery calibration, which doesn't reset the controller, but allows you to adjust the charge level readings, which are often "lies" after prolonged use.
Instructions:
- Completely discharge the power bank before automatic shutdown (indicators must go out).
- Connect it to the charger and wait for full charging (all indicators should burn).
- Disconnect from the network and again discharge to zero by connecting the load (for example, a smartphone).
- Repeat the charging/discharge cycle 3 times in a row.
This method is particularly effective for Xiaomi Mi Power Bank 3 and Redmi Power Bank 20000 models, where there is often a βmemory effectβ of the battery, and once calibrated, the device will begin to accurately display the level of charge and hold the capacity longer.

Calibration of the battery does not replace a full reset, but can solve the problem of incorrect display of charge in 70% of cases.
Common Mistakes and How to Avoid Them
Many users make critical mistakes when trying to reset Xiaomi Power Bank, which leads to a final breakage of the device.
- β‘ Using unoriginal cables β can cause a voltage surge and burn the controller.
- π Interrupting the reset process β if you turn off the device during a software reset, it may stop turning on.
- π§ Attempting to reset on a wet or damaged device is life-threatening!
- π Ignoring full discharge before calibration - leads to inaccurate charge readings.
Also common is the attempt to open the power bank case to access the board, which in 90% of cases leads to loss of warranty and damage to the battery. If the device does not respond to the reset, you should contact the Xiaomi service center.
β οΈ Warning: If after a reset, the power bank stops charging or heats up more than usual, immediately disconnect it from the network and do not use it before diagnosis in the service.
What to do if the reset does not help
If none of these methods worked, the problem may be deeper:
- π Battery wear - after 500-800 Charging cycles, the capacity falls on 30-50%. Solution: Replacing the battery.
- π» Controller damage - often occurs after voltage surges. Solution: Flashing or board replacement.
- π Contact oxidation is particularly important for wet-storage devices.
- π₯ Battery bloating is a dangerous condition that requires immediate disposal.
For diagnosis, you can use a multimeter:
- Put the device in voltage measurement mode (DC 20V).
- Connect the probes to the probes. + and β powerbank contacts.
- Normal voltage of fully charged device: 4.2V Β± 0.1V.
- If the voltage is below 3.0V or is not available, the battery is faulty.
If you are not sure about your skills, it is better to contact an authorized service center Xiaomi. the cost of diagnosis usually does not exceed 500-1000 rubles, and repairs are cheaper than buying a new power bank.
