On Xiaomi smartphones (including the Redmi and POCO lines), battery status information — the Battery Status — is often hidden from the user. The manufacturer restricts access to detailed data on charging cycle, battery wear and temperature, citing “panic protection” of users.
In this article, we’ll break down all the current ways to access Battery Status on Xiaomi, from standard MIUI settings to hidden engineering menus and ADB commands. The methods have been tested on MIUI 12-15 firmware (including global and Chinese versions) and work on models from Redmi Note 10 to Xiaomi 14 Ultra. Importantly, some features may require unlocking the bootloader or root rights – we’ll warn you about this in advance.
1. Standard method: the menu "Battery status" in MIUI
On most Xiaomi smartphones, basic battery information is available through the standard menu, but the manufacturer often hides critical data such as the number of charging cycles or the exact percentage of wear.
Go to: Settings → Battery and Performance → Battery Status
Here you'll see:
- 🔋 Charge level in percentage (sometimes with the last week's schedule).
- ⚡ Battery temperature – but only if it is above normal (usually hidden at values of 25-40)°C).
- ⚠️ Warnings about severe wear (appear only when the container falls below 70%).
Limitation: no data on charging cycle and exact wear. If you want a full diagnosis, read on.
2. Hidden engineering menu: code ##4636##
Some Xiaomi models (especially older or global firmware) have a universal code for the Android engineering menu:
##4636##After entering, the Testing menu will open, where you need to select the Battery information tab.
What can you see here:
- 📊 Level of charge (level) – exact percentage in increments of 0.1%.
- 🔥 Temperature in degrees Celsius (divide the value by 10).
- ⚡ Voltage – Normal for Li-ion batteries: 3.7–4.2V.
- 🔄 Status: Charging, Discharging or Not charging".
⚠️ Note: New models (e.g. Xiaomi) 13/14, Redmi Note 12) This code can be blocked. If nothing happens after you type in, move on to the next method.
💡
If the engineering menu doesn't open, try entering the code in the Phone app instead of through the lock screen. On some firmware, this works.
3. Application "CIT" (Xiaomi Diagnostic Tool)
CIT (Customer Inspection Tool) is Xiaomi’s official service app used in authorized diagnostic centers, showing the actual battery wear as a percentage and the number of charging cycles — data that is hidden in the standard menu.
How to install and use:
- Download. APK-file CIT from a trusted source (e.g. Xiaomi Firmware Updater).
- Install the application (permission to install from unknown sources may be required).
- Open the CIT, select the Battery Test.
- Press the Start Test and wait for the results (the test takes ~30 seconds).
What the test will show:
| Parameter | Meaning | Norma. |
|---|---|---|
| Capacity (Design Capacity) | 4500 mAh (example) | Complies with passport capacity |
| Full Charge Capacity (Full Charge Capacity) | 3800 mAh | 85% of the original - wear 15% |
| Number of cycles | 312 | Up to 500 - the norm, over - degradation |
| Resistance (Impedance) | 120 m | Up to 200 mOhms - good condition |
⚠️ Attention: Annex CIT It might not work on the firmware. MIUI 14+ If the test doesn't run, try alternative methods.
4. ADB-Teams for Advanced Users
If the standard methods don't work, you can get your battery data through Android Debug Bridge (ADB), which requires a computer and enabled USB debugging, but provides the most accurate information.
Instructions:
- Turn on Developer Mode on your phone: go to Settings → About Phone and click on MIUI Version 7 times.
- Return to Settings → Additional → For developers and activate Debugging over USB.
- Connect your phone to your PC, install ADB-tools and execute the command: adb shell dumpsys battery
In conclusion, find the key parameters:
- 📋 health - battery status (2) = Good, 3. = wear).
- 🔄 charge counter - the amount of charge in mAh (compare with passport capacity).
- 🌡️ Temperature: Temperature in tenths of a degree (e.g, 325 = 32.5°C).
- ⚡ Voltage - voltage in microvolts (divided by 1000 for volts).
For advanced diagnosis, use the command:
adb shell dumpsys batterystatsIt will show the history of discharge and charge over the past day.

5. Third-party applications for battery monitoring
If you don't want to mess with ADB or engineering menus, you can use third-party utilities.
- 📊 AccuBattery shows wear, temperature and charging history. Works without root, but the data is approximate.
- 🔍 CPU-Z — Battery tab displays voltage, charge level and temperature.
- 🛠️ 3C Battery Monitor – Advanced Graphics Analysis (requires root for full data).
- 📈 GSam Battery Monitor – monitors energy consumption by application.
⚠️ Note: Apps without root rights show data based on Android ratings, not real sensors. CIT or ADB.
Why is Xiaomi hiding battery data?
Hardware inspection: multimeter and external testers
If the software methods don't give you a clear picture, you can measure the battery's physical condition.
- 🔧 Multimeter (for voltage measurement).
- 🔋 USB-Tester (e.g. Xiaomi) ZMI Power Monitor).
- 🛠️ Screwdriver for disassembling the phone (if you need to check the contacts).
How to check:
- Connect. USB-Tester between charging and phone. Fully charge the battery and see the actual capacity (in mAh).
- Compare it to passport capacity: if the difference is greater than 20%, the battery degrades.
- Measure the voltage with a multimeter on the battery contacts (when the phone is turned off): the norm is 3.7-4.2V.
⚠️ Warning: Disassembling the phone will void the warranty. If you're not sure about your skills, contact the service center.
💡
USB-Tester is the most reliable way to test the actual capacity of the battery, but requires a full charge/discharge cycle (can take 3-5 hours).
7.When to change the battery: criteria for Xiaomi
Even if you get the battery status, how do you know it's time to replace it?
- 🔋 Capacity fell below 70% of the original (for example, 3150 mAh instead of 4500 mAh).
- 🔄 Number of cycles exceeded 500 (for Li-ion batteries).
- ⚡ Phone turns off at 20-30% charge (calibration failure).
- 🔥 Battery heats up above 45°C in normal use.
- ⏳ Battery life has been cut in half compared to the new phone.
If 2-3 points match, it’s time to change the battery. The official replacement at Xiaomi’s service center will cost 1,500-4000. ₽ (Informal workshops may offer cheaper, but the risk of running into a poor battery is higher.
Tip: After replacing the battery, be sure to recalibrate it – completely discharge the phone before turning off, then charge to 100% without interruptions.
