Xiaomi and Redmi smartphone owners often face a situation where strange characters or icons appear at the top of the screen that do not disappear for a long time. The MIUI or HyperOS shell is full of many visual indicators designed to inform the user about the state of the system, but without proper decryption they can only be confusing. Understanding these signals is critical for effective device management.
Pop-ups can address both banal low battery life and serious system errors or malware actions. Ignoring some of these can lead to data loss or increased traffic consumption, while others simply inform about background processes. In this article, we will detail how to interpret each type of notification.
We’ll look at not only standard communication icons, but also Xiaomi ecosystem-specific statuses, such as optimization modes, game accelerators, and superuser rights, and learn to distinguish important system alerts from regular information noise.
It is important to note that the appearance of icons may vary slightly depending on the version of the firmware and the theme of the design, but the semantic load of the status bar remains unchanged throughout the years of development of the line of Redmi Note and Xiaomi Mi.
Main indicators of communication and network
The most common notification group is mobile connection status indicators, where the top bar displays the current network type: 4G, 5G or H+. If you see an “R” icon next to the signal level, it means that the phone is roaming, which can incur additional costs in the absence of a special tariff.
Special attention should be paid to the VoLTE icons and HD. It is clear that voice transmission is carried out through the network. LTE If the badge is missing, the quality of the calls can decrease and the Internet can become slower during the conversation. SIM-card or malfunction.
- 📶 Signal level: number of stripes shows reception strength, empty circle with a line - no network.
- 🔄 Up/down arrows: Blinking arrows show active data exchange; if they burn constantly without user action, it is possible that the app is rocking the update.
- 📡 Access point: the antenna icon with circles reports on the modem modem, distributing Internet over Wi-Fi.
There is also a specific icon in the form of a lock or key that can appear when using secure connections or corporate profiles. Owners of dual-symbol devices are often confused in the GSM 1 and GSM 2 indicators, which indicate which SIM card is active for data transfer at the moment.

System notifications and battery status
The battery is one of the main components of the smartphone, and Xiaomi’s system carefully monitors its condition.The standard battery icon shows the remaining charge, but the color of the lightning inside matters. Green lightning usually means the fast charging option is turned on, and yellow is the energy saving mode that limits the background activity of applications.
If you see a temperature warning, it's a signal to action. Overheating can occur when you play or charge in the sun for long periods of time. The system can automatically limit charging to 80% or slow down the processor to cool the device. Ignoring such notifications shortens the life of the Li-Pol battery.
⚠️ Warning: If the overheating notification appears at rest (the phone is lying down and not in use), this may indicate a battery malfunction or background mining by a virus.
Do Not Disturb mode is displayed as a crescent, in which the phone will not emit sounds or vibrations when incoming calls, except for selected contacts, and often users do not notice the alarm icon that appears after setting the wake time, and forget to turn it off.
For owners of models with AMOLED-The burnout icon is relevant, and it can appear if a static image is on the screen for too long, and the system automatically shifts the pixels to extend the life of the matrix.

MB_06 show the battery status (Good/Bad), MF_05 — number of full recharge cycles.> Security Notifications and Access Rights Ecosystem MIUI It's famous for its aggressive security policies, which generates a lot of specific notifications, and one of the most common is a security alert that warns you of viruses or risky applications. Even if you just installed a program, the system can flag it as dangerous based on the antivirus database, a separate category is the Root rights notifications. If you have received administrator privileges, any request to access system files will be accompanied by a pop-up requesting confirmation.

Another interesting indicator is "Floating Window" or "Parallel Applications." It can be displayed as a small square inside a square, telling you that the application is running in multi-window mode. This is convenient for multitasking, but consumes more RAM. ☑️ Checking for strange icons Reboot device Check system updates View application rights Run antivirus scan: 0 / 4 Rare symbols are not all symbols are found daily.

MIUI 14/15: the ability to group notifications from one application into one folder, which frees up 80% Notices of security, application updates or critical disk errors should remain visible. Turn off only information noise from games, stores and news aggregators.
