How to see the battery status on Xiaomi Redmi: a complete guide with hidden features

Battery status is a key factor in Xiaomi Redmi’s autonomy and performance. Even if the smartphone looks like a new one, a worn-out battery can cut down on 2 to 3 times, cause sudden shutdowns at 20 to 30 percent charge, or overheat while charging. Fortunately, you can check the battery health on Redmi in a number of ways, from hidden engineering menus to third-party apps.

In this article, we will look at all the current diagnostic methods, from standard MIUI tools to professional utilities that show real capacity, the number of charging cycles and even temperature charts. You will also learn what wear indicators are considered critical for battery replacement (spoiler: if the capacity has fallen below 70%, it is time to change the battery).

1. Checking the battery through standard MIUI settings

The easiest way to assess battery health is to use MIUI tools built in, which won’t show the exact capacity per mAh, but will give you an overall picture of the charge consumption and potential problems.

Open the Settings menu → Battery and Performance → Battery status. Here you will see:

📊 Discharge schedule for the last day / week (sharp jumps may indicate a malfunction).
⏱️ Screen time and application activity (if the smartphone discharges in 3-4 hours with moderate use – this is an alarming sign).
⚠️ Warnings about overheating or suboptimal charging (e.g., “Charging suspended due to high temperature").

Note the Battery Use section – if Android System or MIUI Core are the leading systems with a consumption of >15%, this may indicate software failures or battery wear, in which case resetting battery statistics (more on this below) will help.

⚠️ Attention: In some firmware MIUI 14+ The "Battery State" section may not be there. This is not a mistake - Xiaomi sometimes hides it on budget Redmi models (e.g. Redmi). 10A or Redmi Note 11SE). In this case, proceed to the next method.

💡

If the battery status section is not in the settings, try updating the MIUI to the latest version or using alternative diagnostic methods from this article.

2. Hidden engineering codes for battery diagnostics

To test the actual battery capacity, voltage and temperature, you can use hidden service menus, which work on most Xiaomi Redmi models (from Redmi 9 to Redmi Note 13 Pro+), but may vary depending on the firmware version.

Open the Phone app, enter one of the codes and press the call button:

Code.	Appointment	Application
##4636##	Test menu	Shows the battery status, temperature, signal level
##6484##	Battery test	Displays voltage, current, capacity in mAh
##64663##	Information on modules	Includes data on the battery, camera, sensors
##2846579##	Design menu	For experienced users (caution!)

After entering the code ##4636##, select the Information battery.

🔋 Battery level – current charge in percentage.
⚡ Voltage - voltage (normal: 3.7–4.4V; lower 3.5V — battery critically worn).
🌡️ Temperature – Temperature (optimum: 25–40)°C; above 45°C - overheating).
📏 Capacity – current capacity (compare with the passport capacity of your model).

⚠️ Note: Do not enter codes that are not intended for your Redmi model! For example, code ##2846579## on some devices can cause a network reset. If after entering the code the screen is turned off or a warning appears, do not confirm the actions and restart the smartphone.

3. Applications for detailed diagnostics

If the built-in tools aren't enough, third-party utilities will come to the rescue, not only showing the exact capacity, but also plotting discharge graphs, analyzing charging cycles, and predicting the remaining battery life.

Top.-3 Applications for Xiaomi Redmi:

AccuBattery (Play Market) – tracks battery health in real time, shows the number of charging cycles and recommends optimal charge levels to extend life.
CPU-Z – Battery displays voltage, temperature and battery technology (Li-ion or Li-Po).
AIDA64 is a professional tool with detailed battery information, including production date and factory capacity.

Example of data from AccuBattery for Redmi Note 12 Pro:

📉 Health score: 85% (excellent for 1 year old battery).
🔄 Charging cycles: 187 (normal up to 500).
⚡ Discharge rate: 3%/hour in standby mode (norm: 1-2%).

Battery wear |Temperature peaks |Discharge rate to simple |Number of complete charge cycles-->

Important: after installing the app, calibrate the battery — discharge the smartphone to 0% and charge to 100% without interruption.

4.How to reset battery statistics on Redmi

If the smartphone started to discharge quickly after updating MIUI or resetting, the fault may be incorrect battery calibration. the system remembers erroneous data about capacity, which causes the percentage of charge to be displayed incorrectly (for example, from 30% immediately drops to 0%).

To reset the statistics:

Charge Redmi to 100% and disconnect from the network.
Go to Settings → Applications → Application Management.
Find Google Play Services, open Warehouse and click Clear Data.
Reboot the smartphone and discharge it until it is automatically turned off.
Charge to 100% without interruptions (preferably original RAM).

The following is the MIUI 13/14 method:

adb shell dumpsys batterystats --reset

This command must be entered through ADB (instruction below), and after reset, the statistics will be collected again, and the percentage of charge will be displayed more accurately.

⚠️ Attention: Resetting the statistics will not restore the physically worn battery! This only helps with software failures. If after calibration the autonomy has not improved, the problem is the battery itself.

What if the reset didn't help?

If after calibration the battery still discharges in 2-3 hours, check: 1. background processes (c Settings) → Battery → Battery utilization). 2. Optimization MIUI (Turn off Auto Start for unnecessary applications. 3. Connector status USB (If nothing helps, replace the battery (average cost for Redmi: 1,500–3,000) ₽).

5. Signs of critical battery wear

Even without special tools, you might suspect that Xiaomi Redmi battery needs replacement.

🔥 Overheating during charging or when using the camera (temperature above 45)°C).
⚡ Sudden shutdowns at 15-30% charge (indicates a voltage drawdown).
📉 Fast standby discharge (more than 5% per hour without active use).
🔌 Slow charging (for example, from 0% to 100% for 4)+ One hour of using the original scoring).
🔋 Battery bloating (visible from a raised screen or an increased gap between the case and glass).

If you see at least 2-3 signs from the list, it is time to change the battery. It is dangerous to postpone repairs: a bloated battery can damage the motherboard or screen, which will increase the cost of repair by 3-5 times.

For reference, the average battery life in Xiaomi Redmi is 2-3 years (or 500-800 charge cycles), after which the capacity drops to 60-70%, and the autonomy is reduced by 30-50%.

💡

If the battery capacity has fallen below 70% of the factory, it will cost less to replace than repairing a smartphone after an electrolyte swells or leaks.

6. Battery check via ADB (for power users)

For the most accurate data, you can use Android Debug Bridge (ADB), which requires a PC and minimal command line knowledge, but will show real capacity, number of charging cycles, and even temperature history.

Instructions:

Install. ADB-PC drivers.
Turn on USB Debugging on Redmi (Settings → About Phone → MIUI Version → 7 times click on version, then go back to Settings → Additional → For Developers).
Connect your smartphone to your PC and type in the command line:

adb shell


dumpsys battery

In the answer, pay attention to the lines:

Level is the current charge.
Voltage: Voltage (in microvolts, divide by 1000).
Temperature: Temperature (in tenths of a degree, for example 250 = 25.0°C).
charge_counter — current capacity in mkAh (divided by 1000 for mAh).

To get a history of charging cycles, use the command:

adb shell dumpsys batterystats --charged

⚠️ Attention: Teams ADB It may vary depending on the version MIUI. On some firmware (for example, MIUI 14 Global) some data is hidden. If the team returns an error, try updating Platform Tools or using alternative methods from this article.

7.How to extend the life of the Xiaomi Redmi battery

Even if your Redmi battery is still in good condition, these tips will help delay wear and tear by 1-2 years:

🔌 Avoid full discharge (it is optimal to keep the charge between 20% and 80%).
☀️ Do not leave your smartphone in the sun (temperature above 40)°C accelerates degradation).
⚡ Use original RAM (cheap high-current charges reduce the service life).
📵 Turn it off. 5G/LTE, If the signal is weak (constant network search consumes the battery).
🌙 Activate the dark theme (on the AMOLED-The screen saves up to 15% of the charge).
🔄 Update. MIUI (In new versions, the work with the battery is optimized).

For Redmi with fast charging support (33W/67W/120W), it is recommended to:

Do not use turbo mode constantly (it heats the battery).
Charge your smartphone to 80% in 20-30 minutes, then switch to slow charging.

💡

MIUI 14+ has a hidden feature called Optimized Charging. It automatically limits the charge to 80% if you plug in your smartphone overnight. To enable: Settings → Battery → Additional → Optimized Charging.

Frequent questions about Xiaomi Redmi battery
