How to find out the screen time on Xiaomi: a full analysis of statistics

Controlling the time of your display is a key aspect of understanding how your smartphone is used up. Owners of Xiaomi, Redmi and POCO devices often face the challenge of figuring out which app or system process consumes the most power, and this information is critical to diagnosing autonomy issues and optimizing the MIUI or HyperOS operating system.

There are several ways to access this data, ranging from standard settings menus to hidden engineering codes. Standard tools allow you to see the big picture, but more advanced methods may be needed for deep analytics. Usage statistics help not only identify "voracious" programs, but also detect background processes that are imperceptibly planting the battery.

In this guide, we'll take a look at all the options available to check screen time, and you'll learn to interpret the data and make decisions based on accurate numbers, not guesses, and this will significantly extend the life of a single battery charge.

Standard energy analyzer

The easiest and most affordable way to know how long the screen has been running is in the basic settings of the system. Xiaomi has implemented a fairly detailed monitoring tool that collects data in the background. To access it, you need to go to Settings → Battery → Statistics. Here you can see the list of applications, sorted by percentage of energy consumption.

Note that this menu often hides screen time behind total discharge percentages. To see the details, click on a specific application. The window that opens will show screen time and background time, and let you know if you're using the program actively or if it's just hanging in your memory.

However, a standard analyzer does not always show the total screen life for the whole day unless the corresponding widget is installed or the statistics have been reset. The data may be inaccurate if the phone has recently restarted, in which case the system starts collecting again.

• 📱 Click on the app icon in the stats list to see the screen time detailing.
• 🔋 Total discharge percentage does not always correlate with display time due to different code optimizations.
• 🔄 Rebooting the device resets the current statistics, so the data is only relevant from the moment of the last switch on.

⚠️ Note: If you see an app you haven’t used but it has a long screen time, it may indicate a system crash or malware action.

It's important to understand the difference between active use and background activity. Some messengers can show significant uptime even if you haven't opened chats, as they maintain a constant connection to receive notifications. This is normal in today's mobile ecosystem.

Digital Well-Being and Parental Control

A more accurate tool for tracking time spent in front of the display is the built-in Digital Wellbeing feature, which is designed to be self-monitoring and shows a detailed timeline of smartphone usage, and can be found by Settings → Digital Wellbeing and Parental Controls → Control Panel.

Here's a pie chart, where each sector corresponds to a particular application. If you click on a sector or select a specific day on the calendar from the top, you'll see the exact time you spent in each application. The sum of the time you spent using all the applications is actually the screen on time for the period you chose.

The advantage of this method is that it tells a long story, a week or even a month, and it allows you to analyze the dynamics of the gadget, you can notice that on weekends the screen time increases significantly, or you can identify days with minimal activity.

It also allows you to set time limits for specific applications, so if you want to reduce your time on social media, the system will block access to them after the set limit has expired, which is a useful tool for increasing productivity.

• 📊 The usage chart shows hourly activity, allowing you to find peak usage hours.
• ⏱️ Application timers can forcefully block program launches after the limit is exhausted.
• 📅 The history is saved for 30 days, after which the old data is automatically deleted.

It is worth noting that time spent in standby mode or with the screen off (for example, listening to music) is not included in these statistics or marked separately, which helps to separate the actual visual consumption of content from the background tasks.

Hidden Testing Menu and Engineering Codes

For users looking for more technical information, there is a hidden Android test menu that contains raw data on battery status and system life, and to get there, you need to open the Phone app and dial ##4636##.

Once you enter the last digit, the menu will open automatically. You are interested in Battery Usage, which displays technical statistics, including the time since the last full charge and the screen time since the last charge, which is not reset during a normal restart unless a full discharge cycle has been completed.

The interface of this menu is spartan and devoid of the graphical decorations that are typical of MIUI. However, the data here is taken directly from the system kernel, which makes it as reliable as possible, and you can see the exact number of seconds of screen operation, which is useful for accurate calculations.

##4636##

If the code doesn’t work, it could mean that the manufacturer has blocked access to this menu in your firmware version or region, and in such cases, you have to resort to third-party solutions or ADB commands.

⚠️ Note: Be careful with other sections of the test menu. Changing the settings of the radio module or resetting statistics can lead to incorrect display of data in the future.

Using ADB commands for accurate statistics

The most professional method of obtaining information is the use of the Android Debug Bridge debugging bridge (ADB). This method requires connecting the smartphone to the computer through USB-It's a cable, and you have a driver installed and platform tools installed on your PC, and it allows you to pull raw data out of your system logs.

First, you need to enable USB debugging. To do this, go to Settings → About Phone and quickly click on the build number seven times until you notice that you have become a developer. Then, in the Additional → For developers, activate Debugging by USB.

Once you connect your phone to your computer, open the command line or terminal in the ADB folder and type a command to get the full battery statistics. the adb shell dumpsys batterystats command will output a huge log where you need to look for lines containing screen or display.

adb shell dumpsys batterystats | grep screen

This method gives the most detailed picture, including the screen time in different brightness modes and in different running processes. However, log analysis requires some technical knowledge. For the average user, this may be redundant, but for enthusiasts it is the best way to diagnose.

• 💻 You need a computer and an installed Android package SDK Platform-Tools.
• 🔌 The cable should be in good working order and support data transfer, not just charging.
• 📝 The output of a command can contain thousands of lines, so it is better to use filtering through grep or findstr.

Using ADB is safe for user data unless you are performing reset commands or writing system partitions. you are only reading the information the system already stores in memory.

Third-party monitoring applications

If built-in tools are not enough, the market offers a lot of analytics applications, and AccuBattery is the leader in this niche, which not only shows the time, but also calculates battery wear, discharge rate and time remaining to fully discharge at the current rate of use.

Other popular utilities, such as Battery Guru or GSam Battery Monitor, provide detailed graphs and allow you to track wakelocks that keep your phone awake. These apps often have desktop widgets that show your current screen time in real time.

The main disadvantage of third-party solutions is that they consume energy themselves. Constantly polling sensors and maintaining logs can increase battery consumption. 2-5%. Therefore, it makes sense to install such applications temporarily, for diagnostics, and not for permanent use.

💡

Install only one battery monitoring application, and running two of these programs simultaneously will lead to data conflicts and a dramatic increase in power consumption.

When choosing an application, pay attention to the permissions it requests. The analyzer needs access to usage statistics and battery status, and the request for contacts, microphones or geolocations should alert you.

Data Interpretation and Impact on Autonomy

Once you get the numbers, it's important to get them right (interpret them). The normal screen life for a modern smartphone with a capacious battery is between 5 and 8 hours of active use. If your phone shows 2-3 hours at moderate load, this is cause for concern.

The screen life is directly affected by the type of matrix. On devices with AMOLED screens (most flagships Xiaomi) black is not illuminated, which saves energy. On IPS screens, the backlight works constantly, regardless of the color of the image. So the same screen time on different models can give a different percentage of discharge.

Also critical is refresh rate: 120Hz or 144Hz mode significantly reduces battery life compared to the standard 60Hz. In the screen settings, you can choose automatic mode or force the frequency to reduce for savings.

When you analyze the statistics, you always correlate the screen time with the percentage of discharge. If the battery is down by 20% in 1 hour of screen operation, this is an alarm signal. If the screen has gone for only 10-12% in an hour of screen operation, then the device is fine.
