Have you connected Xiaomi to charging, but are not sure if the battery is 100%? Or the phone is silently lying on the table and the screen is out - how to check the charging status without turning it on? In this article, we will analyze all the visual, sound and software signs of full charge for Redmi smartphones, POCO and Mi (including models with AMOLED-screens and indicator on the body).
The problem is that the manufacturer doesn't always make the display obvious: some devices don't have an LED, and MIUI has default notifications turned off. We've put together 7 reliable ways, including hidden system features and hardware features that work even when the screen is off, and we'll also explain why sometimes the phone shows 100% but keeps charging -- and what to do about it.
1. Standard charging indicators on the screen
The most obvious way is to look at the lock screen or the status bar. All Xiaomi smartphones (from Redmi 9A to Xiaomi 14 Ultra) when you connect the charge, you get a battery animation with percentages.
- 🔋 Lock screen: displays the current charge percentage and lightning icon. When the charge reaches 100%, the lightning will disappear, and the percentage will change color from orange to green (for example, the color of the lightning). MIUI 12+).
- ⚡ Status line: In the upper right corner, a lightning battery icon appears. At 100%, the lightning disappears, but the icon remains green for another 5-10 minutes (this is normal - this is how recharging works).
- 📱 AMOLED-Screens: On models with Always-On Display (e.g. Xiaomi 13 Pro), the percentage of charge is displayed continuously, even when the screen is “off".
⚠️ Warning: If the screen does not respond to touches while charging, this may indicate a power controller malfunction or failure MIUI. Try restarting your phone or connecting another charger.
2. LED indicator on the body
Many Xiaomi models are equipped with RGB-LED, which signals the charging status, and its location depends on the series:
- 📱 Redmi Note 8/9/10/11, POCO X3/X4: LED to the right of the front camera.
- 📱 Mi 10/11/12, Xiaomi 13: indicator is integrated into the power button (glows through the slit).
- 📱 Redmi A Series A, POCO M3/M4: LED on the back, next to the camera.
Colors of the indicator and their value:
| Colour | Charging status | Note |
|---|---|---|
| Red/orange | Charging (0–80%) | Blinking – low charge (<15%) |
| Yellow. | Charging (80–99%) | Some models are not available |
| Green. | 100% charge | It burns constantly or goes out after 10 minutes. |
| Blue | Notification (not charging) | For example, a new message |
⚠️ Note: On newer models (Xiaomi 14, Redmi Note 13), the LED can be turned off by default. To activate it, go to Settings → Display. → Notification indicator and enable LED indicator option.
3. Sound signals and vibrations
MIUI, by default, emits an audible signal when it reaches 100% charge, but many users do not hear it.
- 🔕 The sound is turned off in the notification settings.
- 📵 Phone in "Do Not Disturb" mode".
- 🔊 Systemic sound volume reduced to 0.
How to turn on the charging sound:
- Open the Settings. → Sound and vibration.
- Select System Sounds.
- Activate the switch Sound of completion of charging.
Some models (POCO F3, Redmi K40) use vibration instead of sound. If you don't feel the vibration, check:
- 🔧 Vibration settings in Settings → Sound and vibration → Vibration on notifications.
- 🔋 Battery condition: under wear >30% of vibration motors may not work properly.
💡
If the charging sound is annoying but you want to receive notifications, install a third-party app like Google Play's Battery Charge Alert that lets you customize the melody, vibration, and even voice alert.
4. Hidden MIUI features: notifications and charging log
MIUI hides useful charging monitoring tools that not all users know, such as a charging log showing the exact time to reach 100% and a voltage schedule.
How to open a magazine:
- Go to Settings → Battery and Performance.
- Slap the icon. ⚡ in the upper right corner (or select Battery Use History).
- Scroll down to the Charging Log section.
Here you'll see:
- 📊 Time of connection/disconnection of charging.
- 🔋 Current charge level as a percentage.
- ⚡ Charging type (Fast, Wireless, Normal).
Another way is to give a full charge notification, which appears in the curtain, but it's easy to skip, to enable a forced charge alert:
adb shell settings put global battery_full_notification 1This command activates the pop-up window at 100% charge (developer rights required).
Enable the charging log in the battery settings | Check notifications in the curtain | Activate the charging completion sound | View the color of the LED (if any)

5. Features of wireless charging and Power Bank
When charging from a wireless station or Power Bank, the indication may work differently.
- 🔄 Wireless charging: an icon appears on the screen ⚡ At 100%, the inscription changes to Charging complete, but the zipper remains for another 5-15 minutes (this is normal for Qi-standard).
- 🔋 Power Bank: If you connect Xiaomi to an external battery, the indication depends on the model of the power bank. for example, Mi Power Bank 3 flashes a white LED when fully charging the phone.
⚠️ Note: When using non-original wireless stations (especially cheap ones), the phone may show 100%, but in fact the charge will be lower. Check the battery level 10-15 minutes after the shutdown - if it fell by 5-10%, the station is incompatible with the Xiaomi Fast Charge.
Also on some models (Xiaomi 13 Pro, Redmi Note 12 Pro+) when wireless charging, battery cooling is turned on - the phone can vibrate slightly due to the fan operation (this is not a malfunction!).
6.Why is the phone showing 100% but still charging?
This is a normal phenomenon associated with multi-stage charging (Trickle Charging) when the battery reaches 100%, the power controller goes into charge maintenance mode:
- 🔋 First 10 minutes: The phone gets minimal current to compensate for self-discharge.
- ⚡ After 10 minutes: Charging is completely off, but the indicator remains green.
- 📉 With long-term connection (>1 hour: if the charge has dropped to 99%, the cycle repeats.
How to distinguish normal charging from malfunction:
| Sign. | Norma. | Problem. |
|---|---|---|
| Recharge time. | 5-15 minutes | >30 minutes. |
| Body temperature | Warm (up to 35°C) | Hot (>40°C) |
| Charge drop after shutdown | 1-2% per hour | >5% in 10 minutes |
If you suspect a malfunction, check:
- Battery condition in Settings → Battery → Battery condition (wear > 20% requires replacement).
- Temperature via AIDA64 (Sensors section).
- Use the original charger (non-original chargers can give unstable voltage).
What if your phone doesn’t shut down 100% of the charger?
7. Checking the charge on the phone turned off
If the screen is not turned on, but the phone is connected to charging, you can determine the status of the battery as follows:
- 🔋 Short press of the power button: on most models (Redmi Note 10, POCO X3) screen for a split second will show the percentage of charge and the icon of the battery.
- 📱 LED indicator: if it is lit green – charge 100% (see table in section 2).
- 🔊 Connection Sound: When you reach 100%, some models emit a short signal even when the switched off state.
⚠️ Warning: If the phone doesn't respond to the power button and doesn't show an indication, it may be:
- 🔋 Deep discharge (you need to hold on charging for 15-30 minutes before turning on).
- 🔌 Failure of the connector (try wireless charging).
- 💥 Hardware failure (diagnosis required).
For removable battery models (Redmi 4X, Redmi 5A), you can remove the battery for 10 seconds, then insert it back and connect the charging – this sometimes helps to “wake up” the power controller.
💡
If the phone doesn’t turn on and shows no signs of charging, never try to light it from another device through a charger. USB-cable, this can cause a short circuit. Use only the original charger.
