Modern Xiaomi smartphones are equipped with powerful batteries, but even they require constant monitoring of energy levels. Users often face a situation when after updating the system or resetting the usual digital indicator of the percentage of charge disappears from the lock screen or status bar.
In this article, we will take a look at all the ways you can activate this useful widget, where the switches are hidden in the new versions of MIUI and HyperOS shells, and the hidden settings available through the engineering menu, and understanding these processes will allow you to fully personalize your gadget’s interface.
We'll also talk about battery styles that fundamentally change the way you see the remaining energy, and sometimes the problem is not the lack of function, but the design style you choose, which by default hides the digital values, and by understanding this, you can customize the screen in a way that suits you.
Basic display settings in MIUI and HyperOS
The easiest and most common way to return percentages to the screen is to use the standard settings menu. Most current Xiaomi firmware versions have this option in a separate subsection dedicated to battery status. The algorithm for actions may vary slightly depending on the version of the shell, but the overall logic remains the same.
You have to open the main menu and find the Settings section, then follow the Battery path, and that's where all the key power-related options are concentrated, and look at the top of the screen or the Battery Settings tab, where the switch you're looking for is usually located.
- 🔋 Open “Settings” and go to the “Battery” section».
- 📱 Find the item “Percentage of battery” or “Display of charge».
- ⚙️ Select the option you want: “Inside the icon” or “Near the icon».
- ✅ Make sure the switch is activated (blue or green).
Note that in some regions, the firmware names may differ, for example, instead of Battery, the section may be called Power and Performance. If you don't find the right item right away, search by settings by typing in "percentage." The system will highlight the option itself, which will greatly speed up the setup process.
⚠️ Warning: If the numbers don't appear on the lock screen after you turn on the option, try unlocking the device and locking it again.
Customize battery styles and lock screen
Often users forget that the display looks like it depends on the battery style they choose. MIUI and HyperOS shells offer multiple options for graphically displaying the charge level. Some styles only show a graphical scale without numbers by default, which can confuse an inexperienced smartphone owner.
To change the style, you need to go to the battery settings menu and find Battery Style, and here you will be offered a few visual options, choose the one that displays the numbers most convenient for you, usually the first or second option on the list, where the digital value is inscribed inside the circuit of the battery.
Also worth checking is the lock screen settings. In newer versions, you can customize the widgets on the locked screen separately. You may have replaced the watch or status widget with another one that doesn't display power information. Go back to the standard view or add the Battery Status widget manually through the lock screen editor.
💡
Try changing the theme in the Topics app. Some third-party themes may force you to hide your charge percentages by ignoring your system settings. Go back to the standard theme to see if it's the problem.
Use of the Engineering Menu for Advanced Diagnostics
For advanced users who haven't found a standard switch or want to access hidden test settings, there's an engineering menu, a special diagnostic interface built into Xiaomi's firmware, that not only checks the actual battery capacity, but also turns on hidden indicators if they've been locked software.
To enter the menu, you need to open the Phone app and enter a special code. Be careful when entering characters, as one error can lead to opening another section or resetting a call. Once you enter the code, the menu will open automatically, you do not need to go anywhere.
##6485##In the list of parameters you are interested in a line with the designation MB_06 (It's a similar, model-dependent menu that shows the current charge level as a percentage, and although this menu is primarily diagnostic, it allows you to check the system with the actual data from the power controller. If the numbers are jumping or are not displayed correctly, the problem may be calibration.
| Parameter | Description | Value normal |
|---|---|---|
| MB_00 | Current charge level (%) | 0-100 |
| MB_01 | Current voltage (mV) | 3700-4400 |
| MB_06 | Percentage of charge (alternative) | 0-100 |
| MB_10 | Battery status | Good |
It is safe to use the engineering menu as long as you do not change the input fields, but only read the data. However, if you decide to calibrate, follow the instructions for your particular model strictly so as not to damage the software part of the power controller.
What if the code doesn't work?
Problems with widgets and third-party launchers
If system settings don’t work, the reason may be the use of a third-party launcher or widgets. Users who have installed alternative shells (for example, Nova Launcher, Lawnchair) or themes often face display conflicts of system indicators.
Check which widgets are installed on your desktop and lock screen. Sometimes the weather or clock widget overlaps the status bar or duplicates it with errors. Try temporarily removing all third-party widgets associated with the battery and leaving only the standard system indicator.
- 🛑 Remove third-party battery widgets from your desktop.
- 🎨 Temporarily switch to standard theme and launcher.
- 🔄 Reboot the device to reset the interface cache.
- 👀 Check if the percentage appears in the status bar.
Also worth paying attention to is screen resolution and zoom. In rare cases, when you set non-standard resolution or enlarged font, the text of the percentage charge can "go" outside the visible area of the screen. Return the font scale and the size of the interface elements to the default values for verification.
⚠️ Note: When using heavily modified launchers (such as root rights), the status bar can be completely replaced. In this case, turn on the percentage display in the launcher settings, not in the Android settings.
Battery calibration and statistics reset
There are situations where the indicator is on, but it shows the wrong data: the phone turns off at 15% or charges to 100% in 10 minutes, this indicates the desynchronization of the software counter and the real capacity of the battery, in which case a calibration procedure is required, which will help the system learn to correctly display charge again.
Calibration doesn't require complicated tools. You need to completely discharge the device before it turns off automatically. Then, without turning the phone on, charge it until it reaches 100%. Then you can turn on the device. If the indicator is not 100%, continue charging when it's off.
☑️ Checklist of correct calibration
After this procedure, the power controller resets old cycle data and starts building a new discharge schedule, especially for devices that have been in use for more than two years. Full calibration helps eliminate the memory effect in the software, although modern Li-Ion batteries do not physically suffer from this.
If calibration didn’t help and the percentages keep jumping, it’s possible that the physical wear of the battery has reached a critical level, in which case software methods won’t help, and a battery replacement at an authorized service center will be required.
💡
Calibration is a software reset of statistics, not a recovery of battery chemistry. If the battery is physically worn out, calibration will only temporarily hide the problem, but will not solve it.
