Replacement of the battery indicator with Xiaomi Redmi Note: 3 proven ways

The battery indicator on Xiaomi Redmi Note smartphones is a small but important element that shows the current charge level even when the device is turned off. Over time, it can fail: dim, flash incorrectly or stop working altogether. The causes of failure range from mechanical damage to factory defects, but in 80% of cases the problem is solved by self-replacement.

Many users mistakenly believe that replacing the indicator requires a complete dismantling of the smartphone or soldering chips. In fact, the procedure is much simpler – enough accuracy and a minimum set of tools. In this article, we will discuss three methods of replacing (disassembly, non-disassembly and software), discuss in detail the nuances for different models of the Redmi Note (from Note 3 to Note 12), and also warn against typical errors that can lead to damage to the board.

If you notice that the indicator is not behaving properly — for example, it shows 100% charge when connected to a charge, but goes out after a second — this is a sure sign of a malfunction. In some cases, the problem is not the LED itself, but the power controller or firmware, so before replacing it, you should do a diagnosis, which we will discuss below.

1. Diagnosis of the problem: the indicator does not work - what to do?

Before you take on the screwdriver, make sure that the problem is really the indicator, not the software failure or battery damage.

• 🔋 Charging and battery: Connect your smartphone to another charger. If the indicator lights up, there's a problem with the cable or the power supply.
• 📱 Firmware: Update MIUI Up to the latest version through Settings → The phone. → System update: Sometimes, the indicator bugs get fixed in new versions.
• 🔧 Hardware check: Light the flashlight on the indicator area when the phone is off. If you see dim light, the LED works, but there is a problem with the lens or contacts.

If all the points are checked and the indicator is still not functioning, start replacing. On Redmi Note 8/9/10 models, the most common failure is not the LED itself, but the R1203 resistor on the motherboard - it can also be replaced with a soldering iron.

Method 1: Replace the indicator without disassembly (for models with a removable cover)

This method is suitable for older models — Redmi Note 3, Note 4 and some modifications Note 5, where the back cover is removed without special tools.

Step-by-step:

1. Turn off the phone and remove the tray for SIM-map.
2. You can put a plastic card or a mediator on the back, starting at the corners. Be careful, the latches are fragile.
3. Disconnect the battery plume (gently attach the connector with a plastic blade).
4. Find an indicator -- this is a small white or orange LED next to the charging connector -- that can be glued to the case or fixed to the board.
5. Solder the old indicator with a soldering iron (power no more than 30 W!) or gently cut the legs with clippers if it is glue.
6. Set a new indicator, observing the polarity (long leg - plus, short - minus).
7. Put the phone back together.

⚠️

Warning: On the Redmi Note 4X, the light is soldered to the daughterboard, which is also responsible for the on button. Don't overheat it - this can knock out the button!

Method 2: Complete disassembly (for models with a non-removable lid)

The new Xiaomi Redmi Note models (starting with the Note 8) have a non-shattered body, making it difficult to access the indicator, requiring complete disassembly, including removal of the display module, risks: damage to the plumes, detachment of the battery, dust falling under the screen.

Algorithm of action:

1. Heat the back cover with a hair dryer (60-70°C) around the perimeter to soften the glue.
2. Tap the lid with a plastic spatula, starting at the bottom edge (near the USB-C connector).
3. Unscrew 10 screws (Phillips #00) around the perimeter of the middle frame.
4. Carefully disconnect the display plumes, batteries and cameras. Use a suction cup to take the screen off.
5. Find the indicator – on the Note 8/9 it is located on the daughterboard next to the charging connector, on the Note 10/11 – integrated into the main board.
6. Replace the LED with a soldering iron or the entire child board (unless the indicator is a separate element).

⚠️

Note: On the Redmi Note 10 Pro, the indicator is soldered to the main board next to the charging controller BQ25601D. Incorrect soldering can disable the fast charging module!

💡

If you are not sure about your soldering skills, contact the service center. The cost of replacing the indicator in official Xiaomi centers is from 800 to 1500 rubles (2026).

Method 3: Software disabling/activating indicator (without disassembly)

If the indicator is physically functional, but does not work due to a firmware failure, it can be "reanimated" through an engineering menu or ADB-This method does not require disassembly and is suitable for all Redmi Note models.

Instructions through the engineering menu:

1. Open the Phone app and enter the combination: ##4636##.
2. Go to the section Information about the battery.
3. Click on the battery icon 5 times in a row – this will activate hidden settings.
4. Turn on the option to Show the charging indicator (if it is disabled).

Instructions via ADB (for advanced users):

adb shell settings put global battery_light_enabled 1


adb shell settings put global battery_light_color 0xFFFFFFFF

The first command includes the indicator, the second sets the white color (you can replace it with another hex code).

5.Selection of spare parts: where to buy and how not to run into a fake

When buying a new indicator or a child board, pay attention to three key parameters:

1. Article: For Redmi Note 3/4 - XL-5013, for Note 5/6 - XM-6021, for Note 8/9 - DM-7004 (child board).
2. Color of glow: The original lights are white or orange, and red or green is a sign of fake.
3. Seller: Buy only from trusted suppliers – AliExpress (stores with a rating of 98%+), 4PDA Market or official service centers.

Average Parts Prices (2026):

• 💡 Indicator (separate LED) — 100-300 ruble.
• 🔌 Child board (with indicator and connector) USB-C) — 800-1500 ruble.
• 🛠️ Set for disassembly (scapula, sucker, screwdrivers) — 500-1200 ruble.

⚠️

Attention: AliExpress often sells "universal" indicators that are not suitable for Xiaomi. Before buying, check the photo of the spare part with the original (can be found on the iFixit website or in the disassembly on YouTube).

💡

Buy parts with photos of the real product, not stock images, which will reduce the risk of getting a defect or incompatible part.

6. Common mistakes and how to avoid them

Even the skilled craftsmen sometimes make mistakes when changing the indicator. TOP-5 Problems and ways to prevent them:

• 🔥 Overheating board: Use a soldering iron with temperature adjustment (max. 300)°C) and do not keep the stinger longer than 3 seconds in one place. NC-559.
• ⚡ Short circuit: Wrap tweezers with tape before soldering to avoid accidental contact. Check resistance with a multimeter after replacement.
• 🔧 Trail damage: Don't pull the battery or display plumes -- they're attached with fragile latches. Use plastic blades, not metal screwdrivers.
• 📉 Incorrect polarity: The indicator usually has a label "+" Or a long leg is a plus. If you mix it up, the LED won't glow.
• 🧲 Loss of magnetic screws: The screws in the Redmi Note are magnetic and easily lost.Work on a white napkin or use a magnetic mat.

If the indicator does not light up after replacement, check:

1. Integrity of contacts on the board (possibly the track has peeled off).
2. Voltage at the output of the indicator by the multimeter (should be 2.8-3.3V when charging).
3. Power controller performance (on the Note 9 Pro, it is the PM6150 chip).

7. Alternative solutions: if the replacement did not help

In rare cases, the problem is not the indicator, but the other components.

• 🔋 Failed battery: If the battery is swelling or its capacity has dropped below 60%, the power controller can block the display. Check the capacity through AccuBattery or replace the battery.
• 📱 Firmware failure: On some versions MIUI (The indicator is disabled at the kernel level, so the solution is to flash the original firmware through the Mi Flash Tool.
• 🔌 Charging problems: If the phone doesn't detect the charger, the indicator won't work either. USB-C contamination or damage to contacts.

To diagnose the power controller, you can use test points on the board:

On the Redmi Note 8:


Measure the voltage between the TP1203 and GND points (should be 3.8V).




If there is no voltage, the SY6974C controller is defective.
