How to turn off Xiaomi Mi Power Bank: step-by-step instructions for all models

Owners of external batteries Xiaomi Mi Power Bank often face the question: how to turn off the device correctly to save charge or avoid spontaneous discharge? Despite the apparent simplicity, the process of disconnection is nuanced depending on the model, firmware version and even the current state of the battery. In this article, we will discuss all official and alternative ways to turn off, and explain why sometimes the power bank does not respond to the press of a button and what to do about it.

The Mi Power Bank line features a minimalist design with no controls. Most models (such as the Mi Power Bank 3 20000mAh or Mi Power Bank 2S 10000mAh) have only one button that is responsible for turning on, checking the charge level and actually turning off. However, its algorithm is not always intuitive, and some users confuse shutting down (complete power out) with going to sleep, which leads to incorrect actions.

Official method: switch off the button

The most obvious and recommended method by the manufacturer is to use a physical button on the body, but there are important details:

• 🔄 Short press (less than 1 second) – check the level of charge (indicators light up).
• 🔘 Long press (3-5 seconds) – powerbank on/off.
• ⚡ Double pressing (on some models) – switching charging modes (for example, for low-current devices).

To turn off Xiaomi Mi Power Bank with the button, follow the following steps:

1. Make sure that no devices are connected to the power bank (the cables are disconnected).
2. Press the power button for 5-7 seconds until the indicators are completely turned off.
3. Release the button. If the lights go up again, repeat the action.

On USB-C models (such as Mi Power Bank 3 Pro), the algorithm may be different: sometimes you need to hold the button for up to 10 seconds if the device is in fast charging mode. Also, it is worth considering that after a full discharge, the power bank can automatically shut down - in this case, the button will not work until you connect it to the power source.

Automatic Shutdown: When Powerbank Shuts Down

The manufacturer has put in Xiaomi Mi Power Bank several scenarios of automatic shutdown, which many users are not aware of:

• ⏱️ 30–60 seconds inactivity: if the power bank is not connected to the device, it goes to sleep (energy consumption is minimal, but not zero).
• 🔋 Critical discharge: at a charge level below 5%, the device is turned off to protect the battery.
• 🔌 Load Disconnection: If the connected device is fully charged or disconnected, the power bank shuts down after 10-15 seconds.

It is important to understand that sleep is ≠ In the first case, the power bank continues to use energy to maintain the control circuit (about 1-2% per month), in the second case, the consumption is zero.

On models with a display (for example, Mi Power Bank 3 20000mAh with a screen), you can see the automatic turn off timer in the settings menu.

1. Twice press the button to enter the menu.
2. Select the Auto-off (Icon) ⏱️).
3. Set the desired time (from 10 seconds to 5 minutes).

Resetting settings: if the power bank does not turn off

Sometimes Xiaomi Mi Power Bank can freeze after a firmware update or physical damage, for example, in such cases, standard button retention does not help.

1. Shut off all cables from the power bank.
2. Press the power button for 15-20 seconds (before the vibration or flashing of the indicators).
3. If the indicators light up, release the button and repeat a long press to turn off.
4. If there is no reaction, connect the power bank to the charger for 5 minutes, then repeat the reset.

On USB-C PD models (e.g. Mi Power Bank 3 Pro 20000mAh), the reset may require a connection to an 18W+ power supply. If you have a weaker power supply, the power bank will not reset.

⚠️ Warning: Do not use metal objects (clips, needles) to dump, this may damage the button or board.

Shutting down via app (for smart models)

Some Xiaomi Mi Power Bank models (e.g. Mi Smart Power Bank 10000mAh) support management via the official Mi Home app.

1. Connect the power bank to the application via Bluetooth (instructions in Add Device section).
2. Go to the device card and select Settings → Power Management.
3. Press Turn Off (icon) ⏻️).

Please note that this method requires:

• 📱 Smartphone with Android 6.0+ iOS 10+.
• 🔄 Bluetooth 4.2 or newer.
• 🔋 Powerbank charge level not lower than 10%.

If the off button in the app is inactive, update the powerbank firmware via Mi Home or reconnect the device.

Note that USB-C models (such as Mi Power Bank 3 Pro) may have a double tap to activate low current (for headphones or fitness bracelets), in which case it is required to hold the button longer than usual to turn off.

Frequent Mistakes and How to Avoid Them

Many users make common mistakes when trying to turn off Xiaomi Mi Power Bank:

• ❌ Pressing too short: hold the button 1-2 seconds (this is only a charge check).
• ❌ Connected cables: Powerbank will not turn off if a charger or gadget is connected to it.
• ❌ Battery discharge: at a charge level below 5%, the button may not work.
• ❌ Using unoriginal cables: This can block control functions.

If the power bank does not respond to the press, try the following:

1. Connect it to the charger for 10-15 minutes, then try again.
2. Use a different cable (preferably the original Xiaomi cable).
3. Check if the moisture or dust has fallen under the button (clean the toothpick carefully).

💡

If the power bank has not been used for a long time and does not turn on, try to wake it up by connecting it to a power source for 1-2 hours.

Storage and shutdown for a long time

If you plan to not use Xiaomi Mi Power Bank for several months, you need to prepare it correctly:

1. Charge or discharge the battery to 40-60% (optimal level for storage).
2. Turn off the power bank with a long push of a button.
3. Store in a dry place at a temperature of 10–25 ° C.
4. Every 3-6 months, recharge to 50% and turn off again.

Failure to comply with these rules may result in:

• 🔋 Loss of capacity (up to 20% per year with improper storage).
• 💥 Bloating of the battery (when stored in a discharged state).
• ⚡ Loss of calibration of the charge indicator.

⚠️ Warning: Do not store the power bank in the refrigerator or near heat sources (such as in the sun or near the battery) This accelerates the degradation of lithium-ion cells.

💡

The optimal charge level for long-term storage is 40-60%, and full charge or discharge reduces the battery life.
