The current rhythm of life requires constant monitoring of the state of the smartphone, and for users of Xiaomi, Redmi or POCO it is critical to see the exact level of charge. The standard battery icon in the upper corner of the screen is often too abstract, showing only general segments, which does not allow you to accurately estimate the remaining battery life, which is why the function of output of the numerical value in percentage becomes one of the first settings that are changed after buying a new device.
With MIUI and the new HyperOS, this process is simplified by developers, but because of frequent interface updates, the location of the switches can change. Smartphone owners may find a situation where the usual menu has changed, and finding the desired parameter becomes difficult. In this article, we will discuss in detail all the current ways to activate the indicator, including standard menus, hidden engineering codes and third-party solutions.
And we'll also talk about customizing the look of the battery, because a standard widget isn't the only way to monitor power consumption. Understanding how the energy-saving system works and how it interacts with the interface will help you not only customize the screen, but also extend battery life. Let's look at the basic techniques currently available for devices of any price segment.
Standard method of activation through interface settings
The most common and safe way to enable percentage display is to use a regular menu of system settings. This method is suitable for the vast majority of devices running current firmware versions from Xiaomi. The algorithm of actions is the same for all models, whether it is the flagship Xiaomi 14 or the budget Redmi Note, but the names of items may vary slightly depending on the regional version of the software.
First, you need to unlock the device and find the Settings app on your desktop, which usually looks like a gear. After you log in, you should scroll through the list of options available to the item "Notifications and Status Bar" or simply "Stand bar" if the menu is simplified. This section contains all the parameters responsible for the visual design of the top panel of the screen, including hours, Internet speed and SIM card indicators.
Inside this section, you'll need to find a switch called Battery Charge or Charge Percentage. Activating this switch will instantly change the display of the battery icon by adding a digital value to it. If you use Full-screen Apps mode, the numbers can be displayed directly inside the battery icon itself, rather than next to it, depending on the theme you choose.
⚠️ Warning: If the numbers don't appear after switching on, try changing the theme to the standard one. MIUI Themes can have their own styles and block the system settings of the battery display.
It's worth noting that some versions of the HyperOS shell have changed the logic of the menu layout, so that the setting can be on the Settings path → Wallpaper and Personalization → Status bar, which helps you find the visual customization options you want faster without being distracted by system settings.
Setup of battery widgets on the desktop
If you don't have a standard small indicator in the status bar, the system offers a more advanced tool called widgets, which allow you to display charge information on the main screen in the form of large numbers, graphs or stylized images, which is especially convenient for tablets and smartphones with large displays, which allows you to control energy levels without even unlocking the device completely.
To add a widget, you need to go to desktop editing mode, this is done by long pressing the free area of the screen or pinching two fingers to reduce the scale. In the bottom menu that appears, you need to select the button “Vidgets” or “Add widgets”, after which a library of available system components and installed applications will open.
In the widget list, find the Battery category or search. The system offers a range of design options, from simple digital watches with a percentage of charge to complex discharge schedules by clock. Drag and drop items to your desktop will allow you to place them in a convenient location. Some widgets support resizing, which allows you to adapt them to the design of your interface.
- 🔋 Classic widget shows current percentage and time to full charge.
- 📊 Graphic widget displays the history of energy consumption over the past 24 hours.
- 🎨 Stylized widgets change color depending on the level of charge (green, yellow, red).
- ⚡ Optimization Informer allows you to run memory cleaning directly from the battery widget.
The use of widgets has its own peculiarity: they consume a little more resources, as they require constant updating of data on the screen. However, for modern AMOLED matrices, this consumption is negligible. If you use Always-On Display, some widgets can be adapted to display on a locked screen, if your device model allows.
☑️ Checking widgets
Use of engineering menus and hidden codes
For advanced users who don't have the standard settings, there are special codes for logging into the engineering menu, which allow access to hidden diagnostic and testing functions, including detailed information about the state of the battery, but be extremely careful, because changing some parameters can lead to malfunctioning of the system.
To enter the testing mode, open the Phone app and enter the code ##6484##. This combination is standard for most Xiaomi devices and triggers the CIT (Customer Inspection Test) menu. In this menu, you can check battery voltage, temperature and real capacity, but there is usually no direct setting of the percentage display here, although the information here is much more accurate than in the normal interface.
There's also a code called ##4636## that opens the testing menu. You can see the detailed status in the Battery Information section, but again, this is a diagnostic tool. The only way to change the system file to display percent without root rights through the codes is to use the code ##86583##, which forcibly includes the percentages in the status bar on some older versions of MIUI if the standard switch is hidden by the operator.
⚠️ Warning: Don't try to change the values in the engineering menu unless you're sure they're intended.Resetting battery calibration or changing voltage thresholds can cause the phone to turn off when shown 20-30% charge.
If the code doesn’t work, it could mean that your firmware version or regional build is blocking access to these features, so relying on standard settings or third-party apps is the only safe option.
What if the code doesn't work?
Third-party applications for charge monitoring
When system tools are scarce, Google Play apps come to the rescue. There are many utilities that not only duplicate system percentages, but also provide advanced analytics, time forecasts, and beautiful widgets. These applications often have more flexible design settings, allowing you to change the color, font, and position of the indicator.
A popular solution is Battery Widget Reborn, or AccuBattery, which asks for permission to display on top of other windows, allowing them to draw a charge indicator anywhere on the screen, even on top of other applications. Integrating these widgets into the system requires validation of access rights, but once set up, they work stably and do not drain the battery faster than the system.
One of the benefits of third-party solutions is that you can create a fully customized interface, and you can choose to display a percentage as a ring around an icon, a vertical scale, or even an animated character, which is especially true for users who like to personalize their smartphone and make it unique.
- 📱 AccuBattery – shows the real battery capacity and wear rate.
- 🎨 Battery Widget – allows you to create widgets of any size and color.
- 📈 GSam Battery Monitor – Provides a detailed report on which applications are using up charge.
- 🔔 NotifyBuddy – displays charge percentages in the style of Always-On Display on any screens.
When using third-party applications, it is important to monitor permissions, some of which may request access to contacts or locations that are irrelevant to their functionality, and choose proven programs with high ratings and a large number of installations to avoid installing malware that can, on the contrary, speed up the discharge of the device.
Features of display in the mode of energy saving
The MIUI and HyperOS power saving modes are designed to maximize the device’s performance in critical situations. When activated, the system limits the background activity of applications, reduces screen brightness and turns off some visual effects. Smartphone owners often notice that when power savings are turned on, the appearance of the battery indicator can change.
In Battery or Ultra-Economies mode, the system can force the icon to change color to yellow or gray, and hide unnecessary interface elements to save GPU resources. The percentage of charge is usually visible, since this is critical information. However, if you have a third-party theme installed, it can conflict with the energy saving mode, hiding the numbers.
To check your settings, go to Settings → Battery → Energy Saving. You can choose between the “No”, “Battery” or “Ultra” profiles. In the Ultra profile, the smartphone interface is simplified to the maximum, leaving only calls, messages and basic functions, in which the percentage display becomes larger and more contrasting, so that the user always sees the rest of the time.
| Mode of work | Display % | The color of the icon | Impact on the system |
|---|---|---|---|
| Normal. | Standard. | Depends on the topic. | Full functionality |
| Battery | Seems like it. | Yellow/Orange | Limitation of background processes |
| Ultra | Big and bright. | Monochrome | Just calls and texting. |
| Nighttime | Darkened. | dull | Decrease in brightness and blue |
It is important to understand that the mode of energy saving should not be used constantly. Constant operation in the mode of restriction can lead to the fact that you will miss notifications from messengers or mail, as the system will aggressively "kill" background processes. Use this mode only when there is no charger at hand, and far from the socket.
💡
For quick activation of the power saving mode, add a switch to the "Stork" of notifications, which will allow you to turn on energy savings in one click without going into the deep settings menu.
Diagnostics and calibration of the battery indicator
Sometimes users have a problem when the charging percentages “jump” or show an incorrect value, for example, the phone may show 15%, and after a minute it will suddenly turn off, or the charging stops at 99% and does not go further, this indicates the desynchronization of the power controller and software display, which requires a calibration procedure.
Calibration of the battery on Xiaomi does not require root rights and complex equipment. The procedure is a full cycle of discharge and charge. First, you need to completely discharge the device before you turn off yourself. Then, without turning on the phone, put it on charge and wait until the indicator shows 100%. After that, it is recommended to keep the device on charging for another 1-2 hours.
After full charging, you need to perform a forced reboot, which is done by pressing the power button for 10-15 seconds on most models, a procedure that allows the controller to reset old values and write down new capacity limits. If the problem with jumping percentages persists after 2-3 calibration cycles, it is possible that the physical wear of the battery has reached a critical level.
⚠️ Attention: Do not perform full discharge too often. Deep discharge of lithium polymer batteries is harmful to their chemical structure. Use calibration only when there are obvious faults in the display of charge.
To make a more accurate diagnosis, you can use ADB (Android Debug Bridge) commands by connecting your phone to your computer. The adb shell dumpsys battery will display a detailed log of battery status, including charge level, status, and health, a professional method that allows you to see what the system is seeing at the hardware level.
adb shell dumpsys battery | grep levelThis command in the console will show the current charge level in numerical format, ignoring the graphical interface bugs. If the ADB shows 85% and the screen shows 60%, the problem is exactly in the software or the theme of the design. If the ADB shows incorrect data, most likely, you need to replace the battery or the charging plume.
💡
Calibration only helps with software-based display failures, and if the battery is physically worn out, no adjustments will return it to its previous capacity, but it will need to be replaced at a service center.
