Xiaomi's flashlight is a useful feature that often helps when traveling or when power is cut. But what if the LED light or backlight doesn't turn off, draining the device in vain? In this article, we'll look at all the possible ways to turn off the flashlight on the popular models of Mi Power Bank, Redmi Power Bank and other batteries of the brand.
The problem with a flashlight that is constantly burning can occur for a variety of reasons, from accidental pressing of a button to software failures. We have collected proven methods, from simple to technically complex, so you can choose the right option, and you will learn how to prevent spontaneous lighting in the future and save battery life.
Why does the flashlight on Xiaomi’s power bank not turn off?
Before we get to the shutdown, it's important to understand why LEDs can run continuously.
- 🔘 Accidental long-term pressing – on many models, holding the power button for more than 3 seconds activates the constant backlight mode.
- 🔄 Software failure is rare, but the controller of the superbank can “hang” in lighting mode.
- 🔋 Low battery power – some models flash a flashlight at a discharge below 10%, but sometimes the indication is lost.
- 💧 Moisture or dust – can cause the button contacts to close, simulating a press.
If the flashlight caught fire after falling or contacting water, don't try to turn it off programmatically - first dry the device for 24 hours. Attempts to press buttons on a wet poverbank can lead to a short circuit.
Method 1: Standard button disabling
On most Xiaomi models, the flashlight is controlled by the same button as the charge indication.
- Press the button briefly once – this should turn off the flashlight if it was turned on in constant glow mode.
- Hold the button for 3-5 seconds – on some models, this switches backlight modes (blinking/constant light/off).
- Double pressing at 1 second intervals – works on Redmi Power Bank 20000mAh.
If the button does not respond, check:
- 🔍 Contamination of the button - wipe it with an alcohol napkin.
- 🔋 Battery charge – at a level below 5%, some functions are blocked.
- 🔌 Connected devices – disconnect all cables as charging can block flashlight control.

Method 2: Resetting the settings of the overbank
If the flashlight doesn't turn off in the standard way, try resetting the device.
- Connect the superbank to the charger (required original or with Quick Charge support).
- Hold the power button for 10-15 seconds until the lights start flashing in non-standard mode (for example, all 4 LEDs will light up at the same time).
- Release the button and wait for the reboot (about 30 seconds).
This method works on models with a Texas Instruments or Injoinic controller, which are used in most Xiaomi overbanks after 2018.If the reset didn't work, move on to the next method.

Method 3: Discharge and Full Battery Charge
Sometimes the flashlight freezes because of incorrect data on the level of charge, to reset this data:
- Connect to the device (for example, a smartphone) and discharge it until completely disconnected (all indicators will go out).
- Leave the overbank in a discharged state for 2-3 hours.
- Connect to the original charger and charge up to 100% without interruption.
This method helps in 60 percent of cases where the problem is battery calibration. If the flashlight continues to burn after full charging, move on to radical measures.
💡
To speed up the discharge of the overbank, connect two devices to it at the same time (for example, a smartphone and wireless headphones) or use the fast charging mode on the connected gadget.
Method 4: Disassembly and physical disconnection (for advanced)
If the software methods didn't work, there's still the option of disassembling the device.
You'll need:
- 🔧 Plastic blade or mediator for opening the body.
- 🔩 Cross screwdriver (usually) PH00).
- 🧲 Tweezers for working with small details.
- 📸 Camera (to capture the location of the parts).
Step-by-step:
- Carefully shovel the hull seam around the perimeter. Start at the corner where there are no ports.
- Unscrew the screws that fix the board (usually 4-6 pieces).
- Find the LED flashlight – it is located next to the button and marked as LED1 or DS1.
- Unpold one of the LED contacts or snack on the board (unless you plan to restore function).
💡
If you are not sure about your soldering skills, you should contact the service center. Incorrectly turning off the LED can cause the charge controller to fail!
After disassembly, collect the overbank in reverse order, making sure that:
- 🔌 All battery contacts are connected securely.
- 🔧 The screws are twisted without distortion (otherwise the body will not close tightly).
- 🧹 There are no foreign objects under the board (dust, wire clippings).
How to prevent the flashlight from turning on spontaneously?
To avoid repeated problems, follow these tips:
| Problem. | Decision | Models that are relevant |
|---|---|---|
| Accidental tapping in the bag | Use a case or turn off the overbank button before laying | All models with a mechanical button |
| Moisture hits the button. | Plug a protective film on a button or use a silicone case | Mi Power Bank 2/2S, Redmi Power Bank |
| The flashlight is turned on when charging is connected | Disconnect the Verbank from the Network before connecting devices | Mi Power Bank 3 Pro, Mi Smart Power Bank |
| Indicators flash after full charge | Disconnect the network immediately after reaching 100% | All models with Quick Charge |
If you use a flashlight a lot, consider buying a popperbank with a separate backlight button (e.g. Xiaomi Mi Power Bank 3 20000mAh) to reduce the risk of accidental switching on.
Frequent Mistakes and How to Avoid Them
When trying to turn off the flashlight, users often make these mistakes:
⚠️ Warning: Never use metal objects (knives, forks) to press a button.This can damage contacts and cause short circuit.If the button is "recessed", use a plastic shoulder blade or toothpick.
- 🔋 Ignoring charge level – at a charge below 5%, the controller may not respond to pressing. First, charge the power bank to at least 20%.
- 🔌 Connecting unoriginal cables is cheap USB-cables may cause a failure in the operation of the controller, including the spontaneous switching on of the flashlight.
- 💦 Using a verbank in wet conditions – even a slight humidity can lead to the closure of the button contacts.
- 🔨 Disassembly without fixing details – if you decide to open the case, be sure to take pictures of each stage to properly assemble the device back.
If the flashlight continues to burn after all the manipulations and the power bank discharges quickly, this may indicate a malfunction of the controller, in which case the only solution is to replace the payment at the service center.
