How to completely turn off Xiaomi Power Bank: all ways and life hacks

Xiaomi’s power banks have long been synonymous with reliable portable batteries, but even experienced users have questions about how to turn them off properly. It would seem that it could be easier to press a button and ready? In practice, everything is more complicated: some models (Mi Power Bank 3 Pro, Redmi 20000mAh) have hidden energy saving modes, and an improper shutdown can lead to a deep discharge or a controller failure. In this article, we will analyze all official and alternative methods of shutdown, as well as typical errors that shorten the life of the device.

Xiaomi’s superbanks are particularly smart electronics, such as when the device is completely discharged, it can go to sleep-mode and not respond to the push of a button. And USB-C Power Delivery models (like Mi Power Bank 3 20W) have a separate soft-off mechanism, which many confuse with a full shutdown. We tested 12 models of the lineup (from Mi Power Bank 1 in 2015 to Xiaomi HyperCharge 120W 2023) and found universal methods that work on 90% of devices.

1. Standard method: on/off button

The most obvious method is to use a physical button, which is that on most models (Mi Power Bank 2/3, Redmi 10000mAh) it is located on the end of the case and performs several functions at once:

• 🔄 Short press (1 sec) – check the level of charge (indicators light up).
• 🔘 Long pressing (3-5 sec) - on/off of the output voltage.
• 🔋 Super-durable (10)+ Sec: Forced reset (not working on all models).

It's important to understand that when you press the button for 3-5 seconds, the overbank doesn't "switch off" in the usual sense. It just breaks the output circuit, but the internal controller remains active. This is seen by the fact that the charge indicators continue to burn when you connect to the charger. Complete power outage only occurs when the discharge is below 5% (threshold varies depending on the model).

On USB-C PD models (such as Mi Power Bank 3 Pro), the button may work differently:

⚠️ Attention: Mi Power Bank 2S and older models long pressing of the button (10)+ This can cause the charge cycle meter to reset, and it won't hurt the battery, but it will reset the statistics in the Mi Home mobile app.

2. Automatic shutdown: when the overbank turns off itself

All Xiaomi power banks are equipped with deep discharge protection and automatically turn off in three cases:

1. No load 30+ seconds. If the device is not connected to the superbank, it stops applying voltage to the ports after 30-60 seconds (depending on the model), the indicators go out, but the controller remains in standby mode.
2. Critical discharge (<5%) If the charge falls below the threshold, the device completely shuts down, and you need to connect it to the charger for 5-10 minutes to wake it up.
3. Overheating or short circuit: If the temperature exceeds 60°C or detected KZ, an emergency shutdown is triggered, in which case the button does not work until cooling down.

An interesting nuance: in Quick Charge 3.0 models (like Mi Power Bank Pro 2), automatic power-off is faster in 15-20 seconds, done to save energy, but can be confusing if you plug in a device with slow recognition (like some fitness bracelets).

Newer models (Xiaomi HyperCharge, Redmi 60W Fast Charge) have added low power mode, and if the overbank is not used for more than 72 hours, it goes into hibernation, consuming only 0.05 mA/h.

• 🔌 Connecting to a charger (anything, even with low current).
• 🔘 Long press of the button (20)+ seconds).
• 📱 Mi Home (only for Bluetooth models).

3. Software shutdown via Mi Home (for smart models)

Xiaomi Bluetooth-enabled power banks (Mi Smart Power Bank 10000mAh, Xiaomi CyberPower 100W) can be turned off remotely via the Mi Home app.

• 🔋 You forgot to disconnect the verbank from the network and it keeps charging.
• 🔌 You need to stop the power supply to the connected device (for example, at night).
• 📊 Check the usage statistics without physical access.

Instructions for disconnection through Mi Home:

1. Open the app and select your overbank in the list of devices.
2. Go to the Control tab (or Control in English).
3. Press the switch output voltage (or Output Power).
4. Confirm the action if a request appears.

Important: remote shutdown is not physical; Poverbank will remain in standby mode and its controller will consume power (about 0.1 mA/h); to completely shut down, you will still need to press a button or wait for the timer to automatically shut down.

💡

If your superbank doesn't show up in Mi Home, try resetting it to factory settings: press the button for 20 seconds, then plug it into charging.

4.What to do if the overbank does not turn off?

Situations where Xiaomi’s overbank does not respond to the push of a button fall into two categories: software failures and hardware malfunctions, and 80% of cases are resolved without repair.

🔧 Programmatic failures (solved independently)

• 🔄 Hard reset. Connect the verbank to the charger, then press and hold the button. 15-20 Let go when the lights flash. 3 once.
• 🔋 If the reset doesn't work, discharge the superbank to zero (plug in a load like a fan), then recharge it.
• 📱 Firmware update. For Bluetooth models, check for updates in Mi Home (Firmwer tab).

🛠 Hardware malfunctions (require repairs)

• 🔋 Battery bloating. If the case is deformed, it is strictly forbidden to use the superbank - the risk of fire!
• 💧 Moisture is injected. Even if everything is dry, the oxidation of the contacts can block the button from working.
• 🔌 Controller damage often occurs after using uncertified high-current cables.

⚠️ Warning: If the overbank is unloaded or makes extraneous sounds (hisping, crackling), immediately disconnect it from the network and do not use it until the diagnosis.

Check the integrity of the body (if there are any swellings)

Connect another charger (exclude cable problem)

Try resetting settings (15+ seconds of button retention)

Check the reaction to the load (plug the lamp or fan)

5. How to turn off Xiaomi's overbank without a button?

If the button is broken or does not respond, there are several alternative ways:

• 🔌 You're going to zero. You plug in a powerful device like a laptop and wait for it to go full-blown.
• 📱 Through Mi Home. Works only for Bluetooth models. Turn off the output voltage in the app.
• 🔧 Short-circuit. Dangerous method! Carefully lock the contacts of the button with tweezers or a paper clip on the top of the button. 3-5 The risk of damage to the board — 30%.
• ⚡ Use of another charger: Some power banks are turned off if they are connected to a non-standard voltage power source (for example, 9V/2A instead 5V/2A).

For USB-C PD models (such as Mi Power Bank 3 Pro), there is another way: connect the superbank to the PC via a USB-C to USB-C cable and execute the command in ADB:

adb shell dumpsys battery set ac 0

This command simulates a blackout, and the overbank can go into sleep mode. The method does not work on all devices and requires an unlocked ADB.

💡

If the button is broken and other methods do not help, do not take any risks. Contact the Xiaomi service center. The average cost of replacing the button is 500-800 rubles (2026).

6.Typical errors when turning off the superbank

Even experienced users sometimes make mistakes that shorten the life of Xiaomi’s power bank.

• 🔋 Storage in a discharged state, if you leave the overbank off with the charge. 0% for a month, the battery degrades by 10-15%. The optimal level for storage — 40-60%.
• ⚡ Use of left chargers. Output chargers. >3A Without Quick Charge support, the controller may be damaged.
• 🔥 Overheating during charging. If the verbank is hot, it must be cooled first and then turned off. BMS (battery-control).
• 🌡 Storage in cold or heat. Temperatures below 0°C or higher than 40°C accelerates the degradation of lithium polymer cells.

Another common mistake is to shut down frequently, and many users are used to turning off the overbank after each use, but this is not always justified. Modern models (Xiaomi HyperCharge, Redmi 60W) are optimized for standby, and their controllers consume minimal current (0.01-0.05 mA/h); frequent on/offs, on the contrary, increase the wear of the button and contacts.

7 Hidden features: how to turn off the overbank to reset settings

Some Xiaomi models have hidden combinations for resetting or switching to service mode, features that are not documented but can help if the overbank is unstable.

For Mi Power Bank 3 Pro and Redmi 20000mAh:

1. Connect the verbank to the charger.
2. Press the button 5 times in a row at intervals of 1 second.
3. Hold the button on the 6th press for 10 seconds.
4. Release when the indicators start flashing in reverse order.

This procedure resets:

• Charge/discharge cycle counter.
• The output voltage settings (reset to the factory).
• Controller error logs.

The Xiaomi HyperCharge 120W has a separate diagnostic mode that is activated as follows:

Connect to PC → hold the button 15 seconds → release when double blinking of the blue indicator

In this mode, the overbank gives out test voltages (5V/9V/12V/20V) alternately. To exit, you need to press the button again for 3 seconds.

⚠️ Warning: Do not use hidden modes unnecessarily.Incorrect actions can lead to a locking of the output voltage, and the overbank will stop charging the devices before the firmware is reset.
