How to make a flashlight on Xiaomi brighter: from standard settings to modifications

The flashlight in Xiaomi smartphones is one of the most popular tools, but not always its brightness is enough for comfortable use, especially in models of the budget and mid-range segment, where the manufacturer artificially limits the power of the LED. In this article, we will analyze all possible ways to increase the brightness of a flashlight - from standard functions. MIUI before modification of system files.

It is important to understand that not all methods are equally secure, some requiring unlocking the bootloader or superuser rights, which can result in a loss of warranty or unstable device performance. We will detail the risks of each approach so you can choose the best option for your model – be it the Redmi Note 12, POCO X5 or flagship series Xiaomi 14.

If you're looking for a way to make your flashlight brighter without the risk of bricking your phone, start with the first three sections, which contain methods that don't require any interference with system files. For advanced users, we've prepared instructions for modifying your firmware and even hardware (with a warning of the consequences).

1. Standard settings MIUI: stealth

Many users do not know that the MIUI There are hidden flashlight settings that don't appear in the main menu, and these settings depend on the firmware version and the smartphone model, but you should check them first.

The easiest way is to use the “Ultra Bright Flashlight” mode, which is activated through Settings. → Special facilities → Improved flashlight. This option is available on devices with MIUI 13 and newer, but it may not be in budget models (e.g. Redmi) 10A). If the item is not on the menu, try an alternative path:

• 🔍 Open the Settings. → About the phone and 7 times tap on the version MIUI, activate the developer mode.
• 📱 Go back to the main settings menu and find a new section for developers.
• 💡 Scroll down to Hardware Acceleration – there may be a point Maximum brightness flashlight (available on all devices).

Another little-known trick is to use a flashlight gesture, where in some firmware, double-pressing the power button when turned off turns on the flashlight at maximum power (even if it is weaker in normal mode) to activate this function:

1. Go to Settings → Lock screen.
2. Choose Gestures → Double press of the power button.
3. Set up the flashlight.

2. Applications for flashlight control: top-5 utility

If the standard settings don't work, you can use third-party apps to get around the limitations. MIUI And we've got the LEDs to get the most out of it. I mean, some of the utilities require super-user rights, but we've selected the ones that work without them.

Here are the tested applications with a description of their capabilities:

The safest solution is TeslaLED, which requires no root rights and has an intuitive interface.

1. Download. APK from the official website (not from Google Play, as there is a limited version).
2. Allow installation from unknown sources in Settings → Applications → Special Access.
3. Launch the app and move the brightness slider to maximum.

⚠️ Note: Apps that promise brightness increases of more than 150% without root often contain malicious code. 4PDA or XDA Developers.

Modification of system files (for advanced)

If you're willing to take risks, you can change the LED settings directly in system files, which requires an unlocked bootloader and superuser rights, and is only suitable for Qualcomm-based devices (like Snapdragon). 660/732G/870). On MediaTek, the path to files may be different.

The main file responsible for the brightness of the flashlight is called leds-qpnp-flash.kl and is on the way. /system/vendor/etc/. For editing:

1. Install a file manager with root support (such as Root Explorer).
2. Move to the /system/vendor/etc/ and find the file leds-qpnp-flash.kl.
3. Copy it to a safe place (backup!).
4. Open the file in the text editor and find the lines: flash-torch-brightness = 150 flash-max-brightness = 255
5. Change the value to (for example): flash-torch-brightness = 220 flash-max-brightness = 255 Critical warning: Flash-torch-brightness should not exceed 230, otherwise the risk of LED burnout increases by 3 times.
6. Save the file, return it to its place and restart the device.

For devices on MediaTek (e.g. Helio) G88/G96) The path to the file may be different: /system/vendor/etc/leds-mt63xx.kl. The options for editing are similar, but before making changes, be sure to check the up-to-date information for your model on the forums.

⚠️ Warning: Incorrect editing of system files can lead to bootloop (cyclical reboot).If the phone doesn't turn on after the changes, try returning the original file via fastboot or TWRP.

4. Hardware modification: LED replacement

The most radical, but also the most effective, way is to physically replace your LED with a more powerful one, which is only suitable for users with experience in soldering and disassembling electronics, the advantage being that you get a real ultra-bright flashlight (up to 1,000 lumens), but the risks are high: loss of warranty, damage to the board or battery.

Replacement will require:

• 🔧 Soldering station with a thin sting (power not more than 30 W).
• 💡 Cree LED XML-T6 or luminus SST-40 (Compatible with most Xiaomi models).
• 🔥 Flux for BGA-microchip and solder with low melting point.
• 🛠️ Plastic mediator for disassembling the body.

Step-by-step:

1. Turn off the phone and remove the battery (in non-disruptive models, this may require heating the back cover with a hairdryer).
2. Find the LED flashlight on the motherboard – it’s usually located next to the camera andmarked as FLASH_LED.
3. Carefully remove the old LED by heating it on both sides with a soldering iron (don't overheat the board!).
4. Install a new LED while observing polarity (plus and minus should match the original stitching).
5. Check the operability by connecting the battery for a short time (not collecting the body completely).

After replacement, the brightness of the flashlight will increase by 3-5 times, but note:

• 🔋 Continuous operation time will be reduced to 10-15 minutes (due to increased energy consumption).
• 🌡️ The case will heat up more – do not point the flashlight at flammable objects.
• 📵 Possible disruption to work NFC wireless charging (if LED is installed next to antennas).

💡

Before replacing the LED, take a photo of the original board from several angles, which will help to correctly position the new element and avoid short circuit.

5. Alternative light sources: when the flashlight does not save

If you can’t modify a flashlight or want to, consider alternative lighting options.Modern Xiaomi smartphones support several non-obvious features that can replace or supplement the built-in flashlight.

Here are 3 proven ways:

• 📱 Screen as a light source: Install Screen Light or Brightest Flashlight, which uses the display at maximum brightness. Suitable for short-term lighting (for example, finding keys in a bag).
• 🔦 Outside USB-Light: Connect to the phone through OTG compact LED flashlight (for example, Xiaomi Mi) LED Flashlight. It's powered by USB-port and gives 2-3 times more light than the built-in module.
• 📸 Videolight: Enable video recording in mode 4K with flash on – in some models (for example, Xiaomi 13 Ultra) this uses both LEDs at the same time, increasing the brightness by 40%.

For long trips or camping, the best solution would be powerbank with a built-in flashlight. PLM07ZM has an LED for 200 lumens and a capacity of 10,000 mAh – this is enough for several days of autonomous lighting.

💡

Using the screen as a flashlight is the safest method, but it drains the battery quickly. USB-device.

6. Battery optimization for maximum brightness

Often, the flashlight is weaker due to the limitations imposed by the energy saving system. MIUI aggressively optimizing background processes, which can reduce the brightness of the LED. To avoid this, follow the following settings:

Step 1: Turn off optimization for the flashlight application:

1. Go to Settings → Applications → Application Management.
2. Find the flashlight app (or third-party utility you use).
3. Choose the Battery. → Optimizing the battery.
4. Set it up without limits.

Step 2: Set up the performance mode:

• 🔋 Go to Settings. → Battery → Regimes.
• 📈 Choose Performance (instead of Balanced or Charge Saving).
• 🔄 Activate Processor Acceleration (not available on all devices).

Step 3: Check the temperature limits:

Xiaomi automatically reduces the flashlight brightness when it overheats.

• Do not cover your phone while the flashlight is running.
• Use covers with heat-dissipating properties (such as aluminum).
• If the temperature is above 45°C, take a break for 5-10 minutes.

⚠️ Warning: Long-term use of flashlight at maximum brightness when on mode Performance can reduce battery life by 10-15.

7. Frequent problems and their solutions

Even after all the settings, the flashlight can be unstable, and let's look at the typical problems and how to fix them.

If none of the methods helped, check the hardware health of the LED:

1. Turn on the flashlight and shine on the camera of another phone – if there is light, but it is not visible to the naked eye, the problem is in the lens (requires a replacement of the camera glass).
2. Try to turn the flashlight on in safe mode (press the power button). → Shut down. → Hold on to Disable until you go to Safe Mode. If the flashlight is working properly, one of the installed applications is to blame.
