Modern smartphones in the Xiaomi, Redmi and POCO line are equipped with many features for user convenience, among which a special place is occupied by visual process indication. Many owners face a situation when after a system update or accidental reset, the LED indicator at the top of the case ceases to light up, which is a concern, as the user loses the ability to visually monitor the state of the battery, especially in the dark.
Turning on and configuring this interface element is not always an obvious process, as manufacturers often hide the appropriate switches in the depths of the system menus. In addition, there are software features of the MIUI and HyperOS shell that can block the LED when the power saving mode is on. In this article, we will discuss all possible ways of activation, from standard settings to engineering menus.
It's worth noting that the lack of an indicator response is not always a sign of a breakdown, and often the problem lies in a software conflict or specific settings of the theme. If you want to be sure that your gadget is charging or getting a notification even when the screen is off, you need to properly configure the appropriate system settings.
Activation. LED-Indicator through the standard menu
The first and easiest way to bring a flashing light back to life is to check the basic settings of the system. In recent Xiaomi shells, the path to this feature may vary slightly depending on the regional firmware (Global, China, EEA), usually the switch you need is in the section responsible for additional device features or special features.
To access the settings, you'll need to unlock your smartphone and go to the main menu, then look for the Settings item, which is usually presented as a gear. Inside the menu, you'll scroll down to the Additional Features or Special Features section, and that's where LED control is hidden.
If you don't have one on your menu, try searching by settings, type the word "indicator" or "LED" into the search box, and the system will suggest you move to the right item, which is especially true for models with responsive interfaces, where the location of items can change.
⚠️ Note: Some budget models may not have a physical LED, in which case the system uses a screen or flash to notify.
Once the Light Indicator is located, you need to activate the slider, and the system can offer additional settings, such as blinking when the battery is low or when a call arrives, and make sure that all the options you need are turned on.
- 🔍 Open Settings and select the Additional Features section.
- 🔍 Find the light indicator and activate it.
- 🔍 Check for sub-items to adjust the color or frequency of blinking.
- 🔍 Use the search by settings if you can’t find the desired section manually.
💡
If the slider is active but the indicator is not on, try restarting the device, which will restart the system services responsible for the hardware controllers.
Setting up in the "Block screen" and notifications
Sometimes the control of the indicator is placed in a separate subsection associated with the lock screen. This is logical, since the LED works mainly when the display is turned off. In the shells of MIUI 12, 13 and 14, the path often lies through the lock screen menu, and you can adjust not only the presence of the indicator, but also its behavior at various events.
Within this section, look at the Notification Indicator, which allows the LED to light up when you receive messages from social networks, texts or missed calls, and it is important to understand that in order for this feature to work, the applications themselves must have permission to send notifications.
There's also a nuance to the theme. Some third-party themes downloaded from Themes store can take control of the LED or completely disable it for the sake of visual style. If standard methods don't work, try temporarily switching to a standard Classic or Default theme.
| Type of event | Behavior of the indicator | Where to set up |
|---|---|---|
| Charging. | Burning constantly (usually orange/green) | Additional functions |
| Low charge. | Slow blinking (red) | Battery/Productivity |
| Notification | Short-term flashing | Lock screen |
| Missed challenge | periodic flashing | Phone / Call settings |
Remember that in the new versions of HyperOS, some features have been ported over. If you didn't find the items described, they may have been combined with the notification settings of a particular application.
Using the Engineering Menu for Diagnostics
If standard methods fail, you can use more advanced methods of checking. The CIT (Customer Integration Test) engineering menu allows you to test all the hardware components of a smartphone, including the LED, to help you understand whether the module itself is physically working or the problem is solely in the software part.
To enter the engineering menu, open the Phone app and dial the combination ##6484##. If the code is correct, the list of tests will open. Find the LED or Indicator item in the list. When you click on it, you will run a test that should light the LED with a certain color.
##6484##In the test, you might be asked to choose the color of the glow or the blinking mode, and if the LED lights up in the test but doesn't work normally, the hardware is good, and then the problem is solved by resetting or flashing.
⚠️ Warning: Do not change the settings in the engineering menu unless you are sure of their purpose. This can lead to incorrect operation of sensors or screen calibration.
You can also check the driver version and the connection status of peripherals through the engineering menu, which is useful if the indicator stops responding after falling or getting moisture.
- 🛠 Type ##6484## in the phone app.
- 🛠 Choose a test. LED checklist.
- 🛠 Watch the reaction of the LED to the system commands.
- 🛠 If the test is passed, the problem is in the software or settings.
What if the code doesn't work?
Problems with the indicator after the MIUI update
Users often notice the indicator disappearing immediately after an operating system update, a common problem that new configuration files can overwrite user settings or reset them to a default state, which sometimes involves turning off additional features to save power.
In such cases, it is recommended to reset the system's application settings. Don't worry, it won't delete your personal data, photos or contacts. It's about resetting system services such as Settings, Security and System Interface.
To do this, go to Settings -> Apps -> All Apps. Find the Settings app (the gear icon), click About app and select Clean -> Reset. A similar operation should be done with the Security app (the green lightning icon).
Once you do this, the smartphone can restart or simply apply the changes. Check the indicator again. If the problem was a software update bug, this method often helps to return functionality.
💡
Resetting system applications is a safe way to fix interface errors after updating MIUI without losing personal data.
Setting up the low battery charge indicator
The critical charge indicator is an important security element that alerts users to the need to urgently connect their device to the network, and Xiaomi smartphones have a separate setting that can sometimes be disabled by default in some energy-saving profiles.
To make sure you see a warning, go to Battery and Performance, and you'll need to find the charge notification settings here. Make sure you have Low Charge Notification enabled. Usually, the trigger threshold is 10 percent or 20 percent, but you can adjust it on some models.
Also worth checking is the energy saving profile settings. If Ultra mode is activated, the system can limit background processes and LED displays to maximize energy savings. Switch to Balanced or Classic mode if you want the indicator to work at all times.
- 🔋 Go to the Battery and Performance menu.
- 🔋 Check activation of low charge notifications.
- 🔋 Make sure that no energy austerity is included.
- 🔋 Set the alert threshold if this option is available.
Remember that with a fully discharged battery, the indicator may not light up immediately after charging. Lithium polymer batteries take several minutes to set the minimum voltage before the system can start the indication.
Solving problems with Always On Display and the indicator
Owners of smartphones with AMOLED-The screens often use the Always on Display feature (AOD), This is a conflict of interest: if the notification information is already displayed on the screen, the LED may not light up so as not to distract the user and use the charge twice.
In the Always On Display settings (located in Settings -> Lock screen -> Always On Display), there is an option to "Show items when locked." If it is active, the system considers that the visual information on the screen is sufficient, and turns off the LED.
If you want to use an LED instead of a picture on the screen, you have to choose one thing: either turn off the AOD, or accept that the LED will only work when the permanent screen function is turned off or is in sleep mode.
⚠️ Attention: Always On Display increases battery consumption. If the charging indicator is more important to you, consider using a static image instead of animated one. AOD.
You can also set up your AOD schedule, for example, to keep it on during the day and rely on LED lights at night, so you can combine both at different times of the day.
