Owners of modern smartphones Xiaomi, Redmi and POCO often face intrusive behavior of the system when connecting the charger. Instead of simply charging in the background, the phone can turn on the screen, show colorful animations or activate Always On Display mode. This not only distracts the user, but also consumes battery power if the device is used as an alarm clock or information bar at night.
Fortunately, the MIUI shell and the new HyperOS provide flexible tools to manage these processes. You don't have to be an engineer or get root rights to customize the display behavior to your liking. In this article, we'll look at all the methods available, from standard settings to hidden settings, that will help make charging invisible.
Weβll look at both the software switches in the menu and the physical features of the connection that affect screen activation, and understanding these mechanisms will allow you to fully automate the process and avoid excessive glow in the dark.
Why does the screen light up when connecting the cable?
The main reason for activating the display is because of the logic of the Android operating system in conjunction with the developer's proprietary shell, where when the power controller captures the voltage, it sends an interrupt to the system, which in turn triggers a visual response, which is designed to confirm the successful start of charging, but in night-time scenarios this becomes a problem.
The Always On Display (AOD) feature deserves special attention. On many Xiaomi models, this option is set to turn on by default when you set it to charge. Even if you turn off the permanent display of time, the βnetwork connectionβ trigger can force the screen to activate for 10 seconds or leave it burning.
It's also worth considering the proximity and light sensor, and if you're on a table and you're picking it up while you're charging, the screen might light up because of the movement, which some people confuse with the cable response, when the accelerometer actually works.
β οΈ Attention: Constant glow of the screen during charging can lead to uneven wear of the matrix and the occurrence of the effect of burning out pixels, especially on the screen. AMOLED-display.
Understanding what mechanism your phone is waking up is the first step to solving it, which could be system animation, lock widget, or customization.

The screen lights up because of the system response to the power connection event, which can be reconfigured in the interface menu.
Setting up the Always on Display feature
The most common culprit behind glowing screens is the Always On Display feature, which has its own behavioral settings on Xiaomi smartphones, which users often ignore when initially setting up the device, and you need to go to the personalization section to manage this.
Go to Settings and find Always on and Lock (the path may vary slightly depending on the version of MIUI). Here you will see the main function switch. If you completely turn off the AOD, the screen will not burn when charging, but you will lose the ability to see the time on the phone off during the day.
A more flexible approach is to leave the function on but change the activation conditions. The AOD settings menu often includes the option "On for 10 seconds" or "On as scheduled." By selecting Scheduled mode, you can set a time frame for when the screen should glow, eliminating night charging time.
- π± Always turn on: the screen burns constantly while the phone is unlocked or on charge (maximum consumption).
- β±οΈ Turn on for 10 seconds: the screen lights up when notified or touched, then goes out (optimum option).
- π Schedule: allows you to set specific hours of operation of the function.
- π« Disabled: complete deactivation of information display on the locked screen.
It is important to check whether the "Extended Display Time" mode is activated when the charger is connected, and in some versions of the firmware, it is a separate switch inside the AOD menu that forces the screen to be active while charging.
Disabling animation and charging effects
Even if Always On Display is turned off, the phone can show full-screen animations when the cable is connected, and this is a visual effect that shows the percentage of charge and the rate of battery replenishment. On older versions of MIUI, this was standard, but in newer shells, you can get rid of this.
To turn off animation, go to Settings β Wallpaper and Personalization β Effects (or Sounds and Vibrations). This may be where Charging Effects are located. If the switch is active, the system will show graphics every time you insert a USB plug.
Itβs also worth checking the theme settings. Third-party themes downloaded from the Themes store often have their own charging scripts that overlap the system settings. If a standard shutdown doesnβt help, try temporarily switching to a standard Classic or Default theme.
β οΈ Warning: Third-party themes may contain hidden permissions to control the lock screen. If the animation is not disabled by standard methods, change the theme of the design.
In some cases, cleaning the cache of the Themes and Screen Lock application helps. Accumulated temporary files can cause conflicts, causing the screen to light up even when settings are turned off.
π‘
Use a standard design theme to check: if the screen does not light up with it, the problem lies in the code of the third-party theme.
Use of sleep and schedules
If your goal is to prevent the screen from turning on at night, the best way to use the built-in Do Not Disturb or Sleep Mode mode. These features at Xiaomi have advanced settings to control the behavior of the lock screen.
Activate Sleep Mode through the Control Center or in the settings, and find "Block during sleep" in its settings. When activated, the phone not only blocks notifications, but can also turn off screen lifting (Raise to wake) and touching (Tap to wake), which indirectly solves the problem with charging.
In addition, there is a "Block in your pocket" setting in the "Block in your pocket" section. Make sure it's on. Although it's designed to protect against accidental taps in your pocket, this sensor also responds to the lack of light and proximity of objects, which can help to extinguish the screen if the phone is lying on the table with a screen down or in the dark.
For advanced users, the Automator is available (under Advanced Settings or a separate application) and you can create a scenario: "If the time is between 23:00 and 07:00 and the charger is connected β Turn off the screen."
| Function | Where to find out. | Charging effect |
|---|---|---|
| Sleep regimen | Settings β Digital well-being | Disable Tap to Wake and notifications |
| Don't disturb. | Settings β Sound and vibration | Screens off when incoming calls |
| Dark subject matter | Settings β Screen | Reduces the brightness of charging animation |
| Automation | Annex Security/Tools | Full script management |
| Sleep regimen | Settings β Digital well-being | Disable Tap to Wake and notifications |
| Don't disturb. | Settings β Sound and vibration | Screens off when incoming calls |
| Dark subject matter | Settings β Screen | Reduces the brightness of charging animation |
| Automation | Annex Security/Tools | Full script management |
Combining these methods will work best, for example, a sleep schedule ensures that even if you forget to switch your profile, your phone will be quiet.
Hiding notifications on a locked screen
Often, the screen doesn't light up because of the charging itself, but because of the notification that comes in when the cable is connected, and the system processes both events almost simultaneously, and the user sees a bright screen, and the solution is to fine-tune the privacy.
Go to Settings β Notifications and Status bar β Notification format. Select "No text or images" or "Hide content." In this mode, even if the screen lights up, it will only show the lock icon or time, without bright pictures or text messages.
It's also worth checking the settings of specific apps. Messengers like Telegram, WhatsApp, or email clients have their own notification settings. Go to the settings of each and turn off "Pop-up notifications" or "Notifications on the lock screen."
- π System layer: hides the preview of all messages on the locked screen.
- π± Application layer: allows you to leave sound but remove the visual signal for specific programs.
- π Full lock: prevents any application from waking the screen.
This is especially true for group chats, which can wake up your phone with a dozen messages the moment you set it up to charge.

Additional settings for developers
For users who are not afraid to go deep into the system settings, there is a menu for developers. Here you can find parameters that affect the behavior of the screen, which are hidden from the average user. However, beware: changing the wrong settings can lead to unstable system operation.
To activate the developer menu, you need to 7 times click on the build number in the About Phone section. Then a new item will appear in the advanced settings. Look for options related to "Stay awake" - this feature, on the contrary, keeps the screen on when charging, make sure it is OFF.
Customization of window animations may also be present here. Reducing the scale of the animation or completely turning it off (without animation) can make the appearance of the charging screen less noticeable or completely remove it if the system considers the visual response to be excessive.
β οΈ Note: Do not disable the options associated with USB-debugging or configuration selection USB, If you don't understand their purpose, it could disrupt the data transfer or the Fast Charge.
In the newer versions of HyperOS, some settings have been moved or hidden, and if you didn't find the right switch, it's possible that the manufacturer thought the switch was critical and removed the access.

Problems with accessories and chargers
Sometimes the problem is not the software, but the hardware. Cheap or damaged USB cables can create short-term breaks in contact, which the system perceives as multiple reconnection of the device, each time turning on the screen again.
Try replacing the cable or using the original Xiaomi charger. If using another set the screen stops blinking and burning, then it was unstable voltage or poor contact in the connector.
Also worth checking is the phone's connector itself. The buildup of dust and pile in the USB-C port can interfere with the plug's tight fit. Carefully clean the connector with a wooden toothpick or compressed air.
There are also some features of wireless charging: some Xiaomi models behave differently when charging wirelessly than when charging wired, and see if the problem persists with different ways of recharging.

Frequent screen blinking when charging often indicates poor cable contact or port contamination, rather than a software failure.
