How to increase the brightness of the flashlight on the Xiaomi smartphone: from simple settings to deep modifications

Why is Xiaomi’s flashlight dim and can it be fixed?

The flashlight on Xiaomi smartphones is one of the most popular tools, but many users face the problem of insufficient brightness, especially in models of the budget and mid-range segment, where the manufacturer artificially limits the power of the LED to save battery power or comply with the standards for heating. At the same time, flagship devices (for example, Xiaomi 13 Ultra or Redmi K60 Pro) are often equipped with more powerful diodes, but even there the brightness can be increased by software methods.

It is important to understand that dim flashlights are not always associated with hardware limitations. In 60% of cases, the problem is solved by system settings, cleaning contacts or updating the firmware. However, if you own a model with a single-element LED (for example, Redmi Note 10 or Poco X3 NFC), the physical capabilities of the diode can be exhausted - only replacing it with a more powerful module. In this article, we will discuss all the available ways to increase brightness, from safe to extreme, taking into account the risks and features of specific Xiaomi models.

Before you start the modifications, check the basics:

• 🔦 Make sure there is no dirt or protective film on the flashlight lens (a common problem after purchase).
• 🔋 Battery charge above 20% – at low level, the system automatically reduces the brightness.
• 📱 Update the firmware to the latest version (in Settings) → The phone. → Update MIUI).

Method 1: Standard MIUI settings - hidden brightness parameters

Many users are unaware that MIUI has hidden flashlight options that are not available through the main menu, which do not require root rights and work on most models, including the Redmi 9, Poco F3 and Xiaomi 11 Lite.

To open the extended parameters:

1. Activate Developer Mode: Go to Settings → About Phone and tap on MIUI Version 7 times.
2. Return to the main settings menu, open Additional → for developers.
3. Find the flashlight settings option (or Hardware Flashlight Settings in global firmware).
4. Turn on the switch Advanced brightness mode and move the slider to the maximum.

If the flashlight settings item is not in the developer menu, try an alternative method:

##4636## → Equipment testing → Flashlight → Brightness level

⚠️ Note: On some models (for example, Redmi Note 8 Pro) forced brightness increase through the engineering menu can lead to overheating of the LED. If after changing the settings the flashlight begins to blink or turn off - return the values to the standard.

Method 2: Using third-party applications (without root)

If the standard settings don’t work, you can use the apps from Google Play that control the flashlight at the Android API level.

• 📱 Flashlight + LED — Supports brightness adjustment on 80% of Xiaomi models (including Redmi 7 and Mi) A3).
• 🔦 Tiny Flashlight + LED — has a "Turbo" mode for temporary power increase (does not work on all devices).
• ⚡ Super-Bright LED Flashlight – optimized for Snapdragon processors, but may conflict with MIUI 14.

How to set up:

1. Install one of the applications and provide all the permissions requested.
2. In the application settings, look for Brightness Level or Power Mode.
3. Select the maximum value and test the flashlight.
4. If the light is brighter, add the app widget to the home screen for quick access.

Important: Applications cannot exceed the hardware limitations of the LED. If your model has a 1W single-cell diode, no software will make it brighter than 100-120 lumens.

Make sure the app is compatible with your Xiaomi | model

Method 3: Modification through ADB (for advanced users)

If you are ready for deeper settings, you can change the flashlight settings through ADB-This method works on most Xiaomi devices with an unlocked bootloader, but does not require root rights. F2 Pro) and some MediaTek (e.g. Redmi Note 10).

Instructions:

1. Install ADB Tools on your PC.
2. Enable USB debugging in the developer settings.
3. Connect your phone to your computer and execute the command: adb shell settings put global. flashlight_brightness 255
4. For dual-LED models (e.g. Xiaomi Mi) 11) Adb shell settings put global settings flashlight_brightness_dual 255,255
5. Reset the device.

If the command doesn’t work, try an alternative method using sysfs:

adb shell


su




echo 255 > /sys/class/leds/torch-light0/brightness

⚠️ Attention: Wrong commands ADB If the flashlight stopped working after the changes, reset the settings via the command: adb shell settings delete global settings flashlight_brightness

Method 4: Custom core firmware (requires unlocking the bootloader)

To maximize the brightness of the flashlight, you can install a custom core (such as FrancoKernel or ElementalX) that removes software restrictions on LED power. This method is only suitable for advanced users, as it requires:

• 🔓 Unlock the bootloader (destroys all data on the phone!).
• 📥 Custom recaveri installations (TWRP).
• 🛠️ Manual editing of kernel configuration files.

Step-by-step instructions for Xiaomi Redmi K40 (alioth):

1. Unlock the bootloader through the Mi Unlock Tool.
2. Install TWRP for your model (you can download it on the official website).
3. Download the core with enhanced brightness support (for example, Perseus Kernel for Snapdragon 870).
4. V TWRP Sweep through the kernel and edit the file /vendor/etc/flashlight_config.xml, sub-line: <max_brightness>150</max_brightness> on <max_brightness>255</max_brightness>

After firmware, the flashlight brightness can increase by 30-50%, but be prepared for:

• ⚡ Faster battery discharge.
• 🔥 Overheating of the LED during prolonged use.
• 🚫 Loss of warranty (if the device is under warranty).

💡

Before you run the kernel, back up the vendor partition in TWRP, which will help you recover your phone if something goes wrong.

Method 5: Hardware modification - LED replacement

If software methods fail, you can physically replace the LED with a more powerful one, which is suitable for models with a removable back cover (e.g. Redmi 9C, Poco M3) or for those who are ready to disassemble the phone.

• 🔧 Set of screwdrivers (star) T3-T5).
• 💡 New LED (recommended Luxeon Z) ES cree XML2 radiator).
• 🔥 A soldering iron with a thin sting (power not more than 30 W).
• 🛡️ Thermopaste for cooling.

Step-by-step process:

1. Plug off the back cover (use a mediator and hair dryer to heat the glue).
2. Disconnect the battery plume and the camera.
3. Remove the metal plate covering the LED.
4. Drink the old diode and install a new one, observing polarity.
5. Apply the heat paste on the radiator and collect the phone.

⚠️ Warning: Replacing the LED with a higher-power model requires redesigning the cooling system. Without a radiator or a thermal paste, the new diode will overheat and fail. 10-15 Minutes of continuous operation: In some cases, it may be necessary to modify the power driver (for example, replacing the resistor on the board).

Method 6: Alternative light sources – when the flashlight is powerless

If all of the above methods have failed or you are not willing to risk your phone, consider alternative options:

• 🔦 External LED-Lights - compact models for 1000+ Lumen (e.g. Xiaomi Mi) LED Flashlight 2 or Baseus Blade are attached to the back of the phone and powered by the USB-C.
• 💡 Lense nozzles – increase the focus of a standard flashlight (for example, Xiaomi Mi Lens gives you a focus). +40% of the light range).
• 📱 Screen-based apps – Flashlight Screen turns the display into a light source (useful in emergency situations).

Comparison of alternatives:

If you use a flashlight often on hikes or outdoors, an external light source will be more reliable than any software solution. For example, the Xiaomi Mi LED Flashlight 2 provides 5 times more light than a standard Redmi Note 11 flashlight, and does not land the phone battery.

💡

Hardware modifications maximize brightness, but require soldering skills and risk warranty, and alternative lights are the best choice for most users.
