Owners of Xiaomi, Redmi and Poco smartphones often face a situation where an incomprehensible character appears in the status bar, which can be a small letter next to the signal indicator or a strange icon in the corner of the display. Understanding what these elements mean is critical to monitoring the operation of the device. Some of them signal important notifications, others about active functions that can consume battery power.
The MIUI shell (or its new version of HyperOS) contains dozens of system indicators that inform the user about network operation, connected accessories, battery status and activated system functions. Ignoring some of these can lead to unexpected mobile costs or quick discharge of the gadget. In this article, we will discuss each character group in detail.
Indicators of mobile communication and data transmission
The most important area for the user is the top left corner of the screen, where the status of the SIM card is displayed. Here you can see the letters G, E, 3G, H+ or 4G. These indicate the type of connection used. For example, G (GPRS) and E (EDGE) indicate a very slow Internet, available only for text messages in the messengers without pictures.
If you see an H+ or 4G/LTE icon, it means a high-speed connection. However, if there is an up and down arrow next to these letters, there is an active data exchange. Often users do not notice that the background application is eating traffic while this indicator is on, and you can limit the background data transfer in the settings to save.
Special attention should be paid to icons associated with Dual SIM. Xiaomi screens often display the numbers 1 and 2 next to the signal divisions. This indicates which SIM card is used for calls and which is for the default Internet. The confusion here can lead to calls from the wrong card.
⚠️ Warning: If you see a crossed-out SIM card icon or the words "No" SIM", Don't rush to restart your phone. First, check if the card is tightly mounted in the tray. Frequent vibrations when playing or falling can disrupt contact.
There's also a specific R indicator in a circle, which appears when you're roaming outside the SIM card registration region, in which case mobile internet usage may be charged according to the operator's rates, better to clarify the terms in advance or turn off data transmission.
Wi-Fi and Bluetooth connection symbols
Wireless interfaces have their own designations, which are familiar to most users, but they have nuances. A standard Wi-Fi "scapula" can have an exclamation mark inside or be crossed out. This suggests that there is a connection to the router, but there is no access to the Internet. Often the problem lies in the router or the end of the paid period of the provider.
A Bluetooth icon with a stylized "B" appears when the module is on. If there is no small triangle next to it, the device is simply searchable, but not connected to anything. When actively connected to headphones or watches, the icon can be changed or supplemented by an accessory charge indicator in the notification curtain.
Newer versions of HyperOS have smart indicators for the ecosystem. If you use Xiaomi Buds headphones, when you open a case on the screen, animations with the charge level of each headphone separately can pop up on the screen. It's not a permanent icon in the line, but an important interface element.
- 📶 Wi-Fi with exclamation mark: Internet is not available, check the router.
- 📶 Wi-Fi 6: Connecting to a modern network with high speed.
- 🎧 Bluetooth with letters: Type of codec (AAC, aptX), if supported.
- 📡 Access Point: The phone gives the internet to other devices.
Battery status and energy saving modes
The battery charge indicator in the upper right corner is the most visited item, but its behavior varies depending on the settings. Digital percentage display can be included in the Settings menu → Notifications and status bar → Battery charge. It also selects the display style: inside or next to the icon.
When the Power Saving mode is turned on, the battery icon turns yellow, a signal that the system limits background processes, synchronization and brightness of the screen to extend the operation, and if Super-Saving mode is turned on, the color can turn red and the interface will be simplified to a minimum of functions.
When you plug in the charger, lightning appears. If you use fast charging Xiaomi Turbo Charge or HyperCharge, the locked screen can display special animations and text indicating high input power, which is a normal system reaction to a compatible charger.
Hidden battery codes
There's also an overheating indicator, and if the phone gets too hot, you might see a thermometer warning on the screen, and then the system automatically limits charging and performance, and ignoring that signal can lead to battery degradation.
System Notifications and Missed Events
The status bar serves as the main information center, and it's where the envelopes of the emails, the messages from the messengers and the system reminders appear. It's important to distinguish between the permanent icons (left) and the temporary notifications (right) and the permanent ones hang as long as the function is active, for example, the alarm clock is on.
The alarm sign indicates that the alarm is set and active, and if the alarm goes off and is off, the icon will disappear, and the NFC indicator works, and it only appears when the card is read or when you are actively waiting for payment via Google Pay or Mi Pay.
Do Not Disturb mode is indicated by the moon, and in this mode, calls and notifications won't disturb you with sound or vibration, except for exceptions that you'll manually adjust. It's a useful feature for sleeping or meeting, but it's easy to forget, so you need to monitor the icon.
Also worth mentioning is the microphone or camera icon in the top right corner (green dot or orange indicator).This is an Android security feature that lights up when an app right now uses your camera or microphone. If you haven't started the camera, it's worth checking the apps running.
Special Opportunity and Input modes
The inclusion of features for people with disabilities is also displayed in the status bar. For example, TalkBack has its own specific icon, usually in the form of a man or a sound wave. Randomly turning on this feature can make it very difficult to control the smartphone, as the logic of clicks changes.
One-Hand mode compresses the screen for the convenience of large smartphones, often with an icon or a zoom change, usually triggered by a triple tap on the home button or a swipe at the bottom of the screen.
A virtual keyboard can also leave a mark on the system. If you have dictation enabled (a microphone on the keyboard), there may be a Google microphone icon in the status bar, which means that listening is on all the time for voice activation.
- 👁️ Eye: Reading mode or vision protection is enabled.
- 🧤 Glove: Mode of increased sensitivity of the screen.
- 📐 Line: Developer mode or debugging is enabled USB.
- 🔒 Lock: Screen orientation lock enabled.
⚠️ Attention: Debugging by USB" (A gear or a bug doesn't have to burn all the time unless you're a developer, and having this badge when connected to public charging stations can carry the risk of data theft.
Table of decoding rare and specific icons
Some characters are rare and confusing, and they may refer to specific Xiaomi services, game modes, or third-party launchers, and for convenience, we've spread the major ones.
| Badge | Name of name | Description | How to clean up |
|---|---|---|---|
| 🎮 | Game Turbo | The game mode is activated, optimizing resources. | Get out of the Security app → Game Turbo. |
| 📍 | Geolocation | The app uses GPS in the background. | Disable GPS or access to geo-position in settings. |

| 📶 5G+ | 5G SA/NSA | Connection to the fifth generation network. | Settings → SIM-map → Preferred type of network. |
It is worth mentioning the icon separately. VPN (keyboard VPN). It always appears when activated. VPN-Even if you close your browser while the tunnel is running, the icon will hang in the status bar, signaling that all traffic is going through a third-party server.
How to manage the display of icons in the status bar
You can customize which indicators are visible and which are hidden, so you can remove the visual noise and leave only the really important information, and in MIUI 14 and HyperOS, these settings are more flexible.
To change the settings, go to Settings → Notifications and Status bar, where you can turn on the display of Internet speed, battery percentage, and adjust the behavior of notification icons. Hiding unnecessary icons makes the interface cleaner.
☑️ Setting up the status line
Also in the Advanced Settings section, you can find navigation buttons and gestures management, which indirectly affects how you interact with the bottom of the screen, where pop-up notification icons often appear.
💡
Use the Advanced Settings → Design Elements feature to change the style of battery and network icons to make them more visible or minimalistic.
Remember that some system icons, such as alarms or critically low charges, cannot be removed.This is done for the safety of the user so that important events do not go unnoticed.
💡
Flexible status bar settings allow you to remove visual noise, leaving only those indicators that are really important to your use case.
