Xiaomi TVs are a popular choice among users due to their combination of price, quality and functionality. However, over time, any technology requires diagnostics: whether it is checking before buying a used model, assessing wear before selling or just being curious. One of the key parameters is the total operating time of the device, which can tell about the real “age” of the TV even better than the date of production.
Unlike smartphones, where the performance is often displayed in the battery settings, Xiaomi TVs (including the Mi series) TV, Redmi Smart TV Xiaomi TV A doesn't show this information on the home screen, but that doesn't mean you can't get it. In this article, we'll look at all the ways we can go from the official (via the service menu) to the engineering (using the service menu). ADB You will also learn how to distinguish real time from turn on time and why some methods may give inaccurate results.
1.Official way: Xiaomi TV service menu
The most reliable and safe method is to use the built-in service menu, which is available on all Xiaomi models (including Mi). TV 4A, Mi TV 5 Pro, Redmi Smart TV X and newer), but the path to it may differ depending on the firmware version MIUI TV.
To open the service menu:
- Turn on the TV and go to the main screen.
- On the remote, press sequentially: Settings → The device → About the device → Click on the Software Version 5-7 times in a row until the unblock notification appears.
- After that, a new section will appear in the Settings menu - Service menu (or Engineer Mode on English firmware).
In the service menu, look for the Usage Time tab or Total Power On Time tab.
- 📅 Total working hours (in hours or days).
- ⚡ Number of TVs (how many times the TV has switched from standby to work).
- 🔄 Time of last session (last inclusion time).
⚠️ Note: On some models (e.g. Mi) TV Q1 2021) the service menu may be blocked by the manufacturer, in which case try alternative methods from the following sections.
2. via the "Mi Home" app (for smart TVs)
If your Xiaomi TV is connected to the Mi Home ecosystem (e.g. MiOT models), some of the statistics can be obtained through the mobile app. TV Q2, Xiaomi TV A Pro and other “smart” models.
Instructions:
- Install the Mi Home app on your smartphone (available for Android and iOS).
- Add the TV to your list of devices (if it’s not already connected).
- Go to the TV card and look for the Statistics or Uses section.
- It can display total work hours or activity schedules over the past days.
Limitations of the method:
- 📱 Data is only available for MiOT-enabled TVs (usually 2020 and newer models).
- 📊 Statistics can be reset after firmware updates or reset settings.
- ⏳ Time is displayed rounded (e.g., up to the next hour).
💡
If you don't have your time data in Mi Home, try reconnecting the TV to the app: remove it from the device list and add it again, and sometimes it helps update the statistics.
3.Use of ADB-Teams (for advanced users)
For those willing to work with developer tools, there is a way to get time through ADB (Android Debug Bridge.This method works on all Xiaomi Android TVs TV, but requires pre-configuration.
What you need:
- 🖥️ Computer installed ADB (You can download from the Android Developers website).
- 🔌 USB-cable to connect TV to PC (or wireless Wi-Fi connection).
- ⚙️ Included debugging by USB in the settings of the TV (Settings) → The device → Information on the PO → Build Number – Press 7 times, then return to Developer Settings).
Instructions:
- Connect the TV to your computer and open the command line (cmd on Windows or Terminal on the computer). macOS/Linux).
- Enter the command to check the connection: Adb devices must appear serial number of your TV.
- Run the command for working time: adb shell dumpsys power In the conclusion, find the line total_run_time — This is millisecond time. To translate it into hours, divide it into 3 600 000.
⚠️ Attention: Use ADB It can cause failures if you type the wrong commands. Don't change system settings unless you're sure they're there!
Example of the adb shell dumpsys power command
4. Verification through technical passport and service centers
If you need official data (for example, for a warranty or sale), you can contact the Xiaomi service center, they have access to service logs, which fixes:
- 📝 Date of first inclusion.
- ⏱️ Total working time (within minutes accuracy).
- 🔧 History of updates and resets.
How to request data:
- Find the nearest service center on the Xiaomi Service website.
- Provide the TV serial number (located on the back sticker or in the Settings menu) → The device → About the device).
- Ask for a service time report (may be paid if the TV is not warranty).
Advantages of the method:
- ✅ The data are accurate and confirmed by the manufacturer.
- ✅ You can get a history of repairs (if you have been there).
Disadvantages:
- ❌ It takes time (from 1 to 3 days).
- ❌ Possible costs (if the warranty expires).
| Method | precision | Difficulty | Suitable for models |
|---|---|---|---|
| Service menu | ⭐⭐⭐⭐⭐ | Low. | All models. |
| Mi Home | ⭐⭐⭐ | Low. | Smart TV (2020)+) mit |
| ADB | ⭐⭐⭐⭐ | Tall. | Android TV (model) |
| Service centre | ⭐⭐⭐⭐⭐ | Medium | All models. |
| Logs of the system | ⭐⭐ | Very high. | Only for experienced users |
5. Analysis of system logs (for experienced users)
In the depths of the Android operating system TV It stores event logs where you can find on and off times, and this method requires root access or use of special utilities.
How to get logs:
- Install the Logcat Reader app on your TV (available on Google Play for Android) TV).
- Start log recording and find events with PowerManager or DisplayManager tags
- Filter the entries by keywords: screen on, screen off, boot completed.
Example of the inclusion log:
05-20 12:34:56.789 1234 1234 I PowerManagerService: Going to sleep due to timeout (uid 1000)...
05-20 12:35:01.123 1234 1234 I PowerManagerService: Waking up from sleep (uid 1000)...To calculate the total working time, you need:
- 📋 Export logs to a file (for example, via adb logcat) -d > log.txt).
- 🔍 Find all events on/off the screen.
- ⏱️ Calculate the difference between time stamps.
⚠️ Note: Logs can take up gigabytes of memory and contain sensitive information!
Install Logcat Reader on TV
Connect USB-log-storage
Clear the cache before recording (so as not to clutter the logs)
Use filters to find key events

6. Alternative methods: inclusion counters and matrix wear
If you can not get the exact time of operation, you can assess the wear of the TV by indirect methods:
Inclusion counter
Some Xiaomi models keep count of the number of inclusions (for example, Mi). TV 4X). To find him:
- Open the service menu (see Section 1).
- Go to Panel Info or Display Statistics.
- Find the Power On Count option.
The average TV is turned on 2-4 times a day. Multiply the number of turns on by 3-6 hours (average session time) to roughly estimate the performance.
Wear of matrix illumination
Xiaomi’s modern TVs are used LED-It's a backlight that lasts 50,000 to 100,000 hours, and if it gets dim or it gets spots, it can indicate a long period of operation:
- 🔦 Compared to the new TV (on the same settings).
- 📊 Using test images (e.g., gray gradient to check the uniformity of the backlight).
Temperature sensors
The longer the TV lasts, the more the components heat up. If there's a Temperature section in the service menu, check:
- 🌡️ Temperature of the matrix (Panel Temp).
- 🔥 Processor temperature (CPU Temp).
Exceeding 60-70°C in normal use may indicate long-term operation or dustiness.
💡
Indirect methods only give a rough estimate. For accurate data, use the service menu or ADB.
Frequent Mistakes and How to Avoid Them
When checking the time of the Xiaomi TV, users often face some problems:
1. Reset the counter after the update
Some models (e.g. Redmi Smart) TV X50) The time counter is reset after major firmware updates:
- 📥 Before updating, write down the current indicators (take a picture of the service menu screen).
- 🔄 Use local updates (through the USB), Not automatic air renewal.
2.Confusion between “working time” and “inclusion time”
The service menu may display:
- ⏳ Total Power On Time – Total time when the TV was on (even in standby mode).
- 🖥️ Active Display Time – The time when the screen actually showed the image.
The difference between the two can be as high as 20 to 30 percent (for example, if the TV is often left in sleep mode).
3. Firmware incompatibility
On TVs with global firmware (for example, Mi). TV 4S EU) Service menu may be missing or in English:
- 🌐 Install Russian firmware through Mi TV Updater.
- 🔍 Use an interpreter to navigate the menu.
4 Mistakes ADB
If you are connected through ADB error:
- 🔑 Restart the TV and confirm access on the screen.
- 🔄 Reinstall the drivers ADB computer-based.
