Xiaomi devices, from budget Redmis to flagship Mis and POCOs, hide dozens of technical parameters under their concise interface that can be useful for both fault diagnosis and optimization. But where to look for this data? The average user rarely looks deeper than the About Phone section, while it hides information about the processor, sensors, firmware version and even repair history.
This article will help you understand how to view Xiaomi parameters on any device of the brand – whether it is a smartphone on MIUI, a TV with PatchWall or a fitness bracelet Mi Band. We have collected all the relevant methods: from standard menus to engineering codes and third-party applications.
1. Standard Ways: Where Xiaomi Hides the Basic Parameters
To start with, the obvious is the built-in menus, and even if you've never digged into the settings, those paths work on 99% of Xiaomi devices, including the older MIUI 8-9 models and the new ones with HyperOS.
For smartphones and tablets:
- 📱 Basic information: Settings → It's about the phone. It shows the model, the version. MIUI/HyperOS, build number, RAM and memory capacity, on some devices (e.g, POCO F5) You need to click on the line "version" MIUI» 7 Once to unlock the developer mode.
- 🔍 Full specifications: Settings → The phone. → All settings (or “Full Specifications”). In this section, you’ll find data on the Qualcomm Snapdragon, MediaTek Helio processor, screen resolution, battery capacity, and even serial number.
- 📊 Battery status: Settings → Battery → Battery status: Shows current battery wear (if supported) and discharge schedule. Redmi Note 12 and later, also contains information about the number of charging cycles.
For Xiaomi Mi TV and Redmi Smart TV:
- 📺 Firmware version: Settings → On TV. → Software version. You can check for updates here.
- 🔧 Hardware information: Settings → The device → TV information. Shows panel model, processor type (e.g. Amlogic) T972) PatchWall version.
Important: On HyperOS devices (such as the Xiaomi 14 or Redmi K70), the path to some options may be different. If you can’t find the All Settings section, try searching for settings to search for “specification” or “hardware info.”
⚠️ Note: On fake smartphones (e.g., Xiaomi copies) 13T) About phone section can display false data. Check the serial number through the official Xiaomi website at the link.
2. Engineering menu: hidden options for advanced users
If standard menus aren't enough, welcome to the world of engineering code, which allows you to access technical tests, sensor calibration, even hidden network settings, but beware: changing some parameters can cause you to crash.
The most useful codes for Xiaomi smartphones:
- 📞 ##4636## — Phone and battery information, showing network, Wi-Fi, RAM usage and CPU temperature. POCO X6 Pro here you can test the camera and speakers.
- 🔧 ##225## — Calibrate sensors, test accelerometer, gyroscope and compass, useful if the smartphone is not correctly detecting the orientation of the screen.
- 📡 ##4634## — Information on SIM-map and nets. IMEI, signal level and type of connection (4G/5G). On the Redmi Note. 13 Pro+ You can manually select the frequency ranges here.
For Xiaomi TVs, the engineering menu opens differently:
- Turn off the TV.
- Press the Menu + Volume Down button on the remote and hold for 5 seconds while simultaneously turning on the TV with the power button.
- Release the buttons when the service menu with the panel and matrix parameters appears on the screen.
What happens if you change the parameters in the engineering menu?
Expert advice: Before entering the engineering menu, back up your data via Settings → Additional → Backup. On some models (e.g. Xiaomi 12S Ultra), incorrect changes to the RF Test can block IMEI.
Third-party applications: deep dive into technical data
If there are few built-in tools, third-party tools come to the rescue, not only showing the parameters, but also comparing them to reference values, helping to identify malfunctions or fakes.
Top.-5 Applications for Analysis by Xiaomi:
| Annex | What shows | Link (Google Play) | Features |
|---|---|---|---|
| CPU-Z | Processor, RAM, GPU, sensors, battery | Download | Shows the real clock speed of the cores (useful for checking the trottling on the Snapdragon 8 Gen 2) |
| AIDA64 | Complete Iron Diagnostics + Performance Tests | Download | Can export the report to the file (useful for warranty repair) |
| AccuBattery | Battery condition, charging cycles, wear and tear | Download | Calculates the actual battery capacity (for example, if the Redmi Note 11 shows 5000 mAh, but in fact 4200 mAh) |
| Mi Check | Verification of originality of the device by IMEI and SN | Download | Verifies data with the base Xiaomi (works only on official firmware) |
Critical: Apps like AIDA64 can show incorrect CPU data on smartphones with a bootloader unlocked. For example, MediaTek Helio G99 can be defined as Helio G96 because of the custom core.
Xiaomi TVs are suitable for TV Hardware Info (available on Google Play for Android TV).
- 🖥️ Type of matrix (IPS, VA, OLED) and its manufacturer, for example, BOE or Samsung Display).
- 🔊 Settings of the sound system (number of speakers, Dolby Atmos support).
- 📡 Wi-Fi and Bluetooth versions (important for diagnosing connection issues).
4.Parameter Verification through ADB: for developers and enthusiasts
If you want the most accurate data (for example, to debug or modify firmware), connect the device to your PC and use ADB (Android Debug Bridge), which works on all Xiaomi devices, including those that have disabled access to the engineering menu.
Step-by-step:
Install Platform Tools on PC
Enable USB debugging in the developer settings (Settings → About Phone → MIUI version → tap 7 times)
Connect the device via USB (select File Transfer mode)
Run the command line in the folder with adb.exe
-->
Mainstream ADB-commands to check parameters:
adb shell getprop ro.product.model #Model
adb shell cat /proc/cpuinfo # Processor information
adb shell dumpsys battery # Detailed battery status
adb shell dumpsys power # Energy consumption data
adb shell settings list system # All system settingsFor Xiaomi TVs, the commands are similar, but require a network connection:
adb connect [IP-address TV]:5555
adb shell dumpsys display # Display information
adb shell dumpsys audio # Sound settings⚠️ Note: Adb shell su commands on devices with a locked bootloader lead to a hard brick (complete loss of performance). On Xiaomi with HyperOS, this is especially critical - recovery is possible only through an authorized service center.
5. How to check Xiaomi settings before buying used
When buying a device from hand, checking the parameters helps to avoid cheating.
For smartphones:
- 🔋 Battery status: In Settings → Battery → Battery status, see Capacity if it is below 80% of the declared value (e.g. 3200 mAh instead of 4,000 mAh on Redmi). 9A), battery.
- 📱 Screen originality: In the engineering menu (#225##) run the display test. Xiaomi copies often have cheap ones OGS-color-render.
- 📡 IMEI Serial number: Check it against the data on the box and through the Xiaomi website. IMEI It can be duplicated or belong to another model.
For TVs:
- 🖥️ Matrix Elapse Time: In the engineering menu (see Section 2), look for Panel On Time. If the value exceeds 30,000 hours (≈10 years at 8 hours of work a day, prepare for the imminent replacement of the panel.
- 🔊 Speaker Quality: Enable the test signal through Settings → Sound. → On worn-out TV, sound can wheez or disappear at high frequencies.
💡
Before buying used Xiaomi, ask the seller to take a screenshot of the All Options section and check it through the IMEI.info service. This will help to identify inconsistencies in the characteristics (for example, if the seller claims that this is Xiaomi 13 Pro, and IMEI is determined by POCO X5).
6. Frequent problems and their diagnosis by parameters
Some malfunctions Xiaomi can be detected even before the appearance of obvious symptoms – just know what parameters to check.
Problem: Fast battery discharge
- 🔋 Check the Settings. → Battery → Battery use: If the top consumer is Android System or Mediaserver, it's the software's fault.
- 📉 In AccuBattery, see the discharge graph. Abrupt surges (e.g., from 200 mA to 1000 mA) indicate a malfunction of the power controller.
Problem: Processor overheating
- 🌡️ V CPU-Z or the engineering menu (#4636##) check the temperature.+ Gen 1 under load - up to 70°C. If above, thermopaste replacement is required.
- ⚙️ V ADB Adb shell dumpsys thermalservice will show which areas are overheating (CPU, GPU, battery).
Problem: Bad network signal
- 📡 On the engineering menu (##4634##) look at the parameters RSRP and RSRQ. Optimal values: RSRP: higher -90 dBm (good signal) RSRQ: higher -10 dB (stable connection)
- 📶 If the signal is weak, check if the range is off. 5G customized SIM-maps (Settings) → SIM-maps and mobile networks → Preferred type of network).
💡
If the parameters of the Xiaomi smartphone displays the MediaTek Helio G85 processor, and in fact the device brakes like on the Helio G35, most likely, the seller replaced the motherboard. Check this through AIDA64 (section “CPU”).
