The charging indicator on Xiaomi smartphones is a small but important element that signals the state of the battery. If it stops glowing, flashing incorrectly or even falls off, this not only spoils the appearance of the device, but also deprives the user of visual control over charging. In most cases, the problem is solved by replacing an LED or flexible plume, but many are afraid to take up repairs on their own, for fear of damaging the fee or battery.
In fact, replacing the battery indicator is one of the easiest procedures in Xiaomi repairs, if you approach it with preparation. In this article, we will analyze all the steps from fault diagnosis to selection of spare parts and installation. Redmi Note 8/9 Pro, Poco X3 mi 10T And for those of you who are not willing to take risks, we'll tell you how to avoid the typical breakdown errors, and what to do if the indicator doesn't work after you've changed it, and for those of you who are not willing to take risks, we'll tell you how much it costs to repair the service center and how to choose a reliable master.
Before you start, answer one question: have you tried to clean the contacts of the indicator with alcohol? If not, perhaps the problem is solved without disassembling the device. If so, then we will begin to analyze the process in detail.
Causes of failure of the charging indicator
Before you take a phone apart, it's important to understand why the light stopped working, and 60 percent of the time, the problem isn't with the LED itself, it's with the associated elements.
- 🔋 Contact oxidation – moisture or sweat over time destroys copper tracks on the plume or board, especially for devices that are often used during charging.
- 💡 Burned LED - occurs due to voltage surges (for example, when using low-quality chargers). RGB-indicator (Poco) F3, Redmi K40).
- 🔌 The damage to the flexible plume is caused by a careless disassembly or fall of the phone, and the indicator plume often goes along with the power button plume.
- 🔧 Software failure is rare, but it happens that the indicator turns off after updating the firmware.
How do you diagnose a problem without disassembling? Connect your phone to charge in a dark room and look closely at the area of the indicator, and if the LED barely glows or flashes intermittently, it's probably the contact problem. If it doesn't glow at all, but the phone is charging, it's either the LED itself or the plume. 12T and a newer indicator may not work due to the disabled function in the settings MIUI — Check the Settings section → Battery → Charging indicator.
⚠️ Warning: If the indicator stopped working after a phone drop or moisture hit, don't be in a hurry to change it. First check the integrity of the board with a multimeter - other components may be damaged.
2 What tools and spare parts will be needed
To replace the battery indicator with Xiaomi, you need a minimum set of tools, but you should not save on quality - cheap plastic blades can break and scratch the case.
| Tool/part | Appointment | Where to buy | Cost (2026) |
|---|---|---|---|
| Setting screwdrivers (T2, T3, T4, PH00) | For spinning the screws of the back cover and board | AliExpress, Beru, Ozone | 200–500 ₽ |
| Plastic shoulder blades (mediators) | For careful putting of the cover and plumes | Any electronics store | 50–150 ₽ |
| Fryer-dryer | To soften the glue under the battery (if required) | AliExpress, Radio Detail Markets | 800 ₽ |
| LED/LED indicator plume | Replacement Part (Select the Phone Model!) | AliExpress, eBay, local service centers | 100–400 ₽ |
| Isopropyl alcohol (90%+) | To clean contacts and remove glue residues | Pharmacy, chemistry stores | 100–200 ₽ |
When choosing parts, pay attention to compatibility. For example, for the Redmi Note 8 Pro and Redmi Note 9 Pro, the indicators are similar in appearance, but have different connectors on the plume, it is better to buy parts from trusted sellers with a rating above 95% and reviews with photos. If you are not sure about your phone model, use the app. CPU-Z Check the sticker under the battery (the exact model number is indicated).

⚠️ Warning: Don't use metal blades to smear plumes, they can close contacts on a board. If you don't have plastic tools, you can gently work with a guitar mediator or a bank card.
Step-by-step instructions for replacing the indicator
The process of replacing the charging indicator can be divided into 4 stages: disassembling the phone, dismantling the old indicator, installing a new one and building. Below is a universal instruction that is suitable for most Xiaomi models (exceptions are indicated separately).
Stage 1: Disassembly of the phone
1 Turn off the phone and remove the back cover. Most models have it on latches and glue. Carefully put the lid on a plastic blade, starting at the corner next to the tray for the lid. SIM-On the Xiaomi Mi 11 and newer, the cover can be glued especially hard – use a hair dryer (heat to 60-70).°C).
2 Unscrew all screws that fix the metal plate above the battery. Be careful: on some models (Poco) X3) The screws are of different lengths – remember where it was.
3. Disconnect the battery plume from the motherboard, and for that, gently put the connector on a plastic spatula. Don't pull the wires!
Step 2: Dismantling the old indicator
1. Find the charging indicator -- usually located next to the USB-Type C connector or under the battery. 8/9 The LED is soldered into a flexible plume that goes along with the power button. 10/11 The indicator may be a separate module.
If the indicator is in the plume:
- Carefully disconnect the plume from the board (the connector is usually signed as LED_FPC).
Check the integrity of the tracks on the plume - if they are damaged, you will need to replace the entire plume.
If the indicator is soldered:
- Heat the soldering place with a hair dryer (temperature 250-300)°C) and tweez the LED carefully.
- Clear the contacts on the board with alcohol.
Step 3: Installation of a new indicator
1. If you have a track with an indicator:
- Connect the new plume to the board, make sure the connector sits tight, sometimes you need to push a little.
2. If you have a separate LED:
- Put some flux on your contacts and solder a new LED. Watch for polarity! The long leg of the LED is the anode (+), short-cathode (–).
3. Check the indicator by temporarily connecting the battery. If it does not glow, check:
- Correct connection of the plume.
- Integrity of tracks on the board (you can call the multimeter).
- Settings MIUI (on some firmware, the indicator is disabled programmatically).
Stage 4: Assembly of the phone
1.Make sure all plumes are connected correctly and there are no clamps anywhere.
2.Turn all screws (do not pull!).
3. Stick back cover. You can use double-sided tape for reliability. 3M 9448A glue B-7000.
4. Frequent mistakes and how to avoid them
Even experienced craftsmen sometimes make mistakes when changing the indicator, and here are the most common ones and ways to prevent them:
- 🔧 Damage to the battery plume occurs when you unplug neatly. Always pull the connector on the side instead of pulling it up.
- 🔥 Overheating of the fee when soldering - if you hold the hair dryer for too long, you can move away BGA-Use a temperature not higher than 300.°C and heat no longer than 10 seconds.
- ⚡ Forgetting to turn off the battery can lead to short circuits. Always disconnect the battery plume before working with the board!
- 🔄 Confuse the polarity of the LED – if the indicator does not work after replacing, check whether the anode and cathode are connected correctly.
Another common problem is that when you change the light, it glows all the time, even when the phone's not charging, and that means that the circuit is closed.
- Turn off the battery.
- Check the resistance between the LED contacts with a multimeter (there should be infinity in the off state).
- If there is resistance, look for a circuit on the board or a faulty plume.
What if the indicator flashes in an arbitrary mode after replacement?
5.How much does it cost to replace a service center
If you don’t want to take the risk of having your phone repaired, the prices for replacing the battery indicator in 2026 vary by model and region:
| Model phone | Cost of work (₽) | Cost of the spare part (₽) | Total price (₽) |

How to choose a good service center?
- Check out reviews on Yandex.Maps or 2GIS – pay attention to the latest reviews (2023-2026).
- Ask if they have a job guarantee. The minimum period is 1 month.
- Check if they're using original parts or analogs. It's not critical for the indicator, but for the plumes, it's better to use the original.
💡
If the service refuses to show the replaced part or does not give a guarantee, it is a reason to be wary.
6. Alternative solutions: if the indicator does not want to work
What if changing the indicator didn't help or you're not ready to take your phone apart? There are several alternative ways to get back visual control of charging:
- 📱 Battery widget on the lock screen - in MIUI You can turn on the percentage of charge even on the locked screen. → Lock screen → Widgets → Battery.
- 🔔 Charging Notifications – Set up alerts when you reach a certain level of charge. Use MacroDroid or built-in settings to do this. MIUI.
- 💡 External LED indicator - you can buy USB-extension device with built-in charging indicator (stands) ~200 ₽). Connect it between charging and phone, and the LED on the cable will signal the process.
- 🔋 Charging station with display – some wireless charging (e.g. Xiaomi Wireless Charging Pad) 20W) show the charge level on the built-in screen.
If the problem is a software glitch, try resetting your phone to factory settings.
- Go to Settings → About the phone → Reset settings.
- Select Reset all settings (does not delete files, but resets system settings).
- After restarting, check the indicator.
