How to check charging cycles on Xiaomi: official and hidden methods

The smartphone battery is one of the most vulnerable components, which gradually degrades with each charging cycle. Manufacturers, including Xiaomi, often do not advertise the real state of the battery, limiting themselves to vague phrases like “normal wear.” Meanwhile, the number of charge cycles is a key indicator that directly affects the capacity and battery life of the device.

In this article, we’ll look at all the ways you can check charging cycles on Xiaomi, Redmi and POCO smartphones, from standard MIUI tools to hidden engineering menus and ADB commands. You’ll learn how to interpret the data, what values are considered critical, and what to do if the cycle counter resets after firmware. Particular attention is paid to models with Qualcomm Snapdragon and Mediatek, because the methods for them are different.

What are charging cycles and why should they be checked

A charging cycle is the complete process of discharging and then charging the battery from 0% to 100%. For example, if you charge your phone today from 20% to 80% and tomorrow from 80% to 100%, this will be considered one full cycle. Manufacturers usually guarantee that at least 80% of the capacity is saved after 500-800 cycles (depending on the type of battery and fast charging technology).

Why is this important to Xiaomi owners?

• 🔋 Capacity degradation: After 300-400 cycles, the battery may lose 15-20% of capacity, which will lead to a reduction in operating time by 2-3 hours.
• 📉 Impact on productivity: Starting with MIUI 12, the system limits maximum charging to 95-98% over a large number of cycles to extend the life of the battery.
• 💰 Replacement cost: The official battery replacement in the service center costs 3-7 thousand rubles (depending on the model), so monitoring cycles helps to plan the budget.

In practice, users often experience a smartphone that starts to run out of power after 1 to 1.5 years of active use, not only due to natural wear, but also due to incorrect calibration of the power controller, which can reset the cycle counter or show inaccurate data.

Method 1: Standard Battery Status Menu in MIUI

The simplest, but also the most limited method is the use of the built-in MIUI tool. It is available on all Xiaomi smartphones since the MIUI 10 firmware version, but it does not show the number of cycles, but the total battery life and its current capacity.

To open the menu:

1. Go to Settings → Battery and Performance → Battery status.
2. Click on the gear icon (⚙️) top-right.
3. Select Battery Data (on some models - Battery Information).

Here you will see three key parameters:

• 📊 Level of wear (e.g., “Good condition” or “Mediocre wear»).
• ⚡ Current capacity (in mAh) – compare with the passport capacity of your model.
• ⏱️ Operating time – total time of use since first inclusion.

Unfortunately, the number of cycles is not shown here, and this method is only suitable for a superficial assessment of the state of the battery, and for accurate data, alternative methods will have to be used.

💡

If the Battery Status menu does not have Battery Data, upgrade to the latest version or use the ADB method (described below).

Method 2: Engineering menu (#4636###) – not available on all models

The hidden engineering mode allows you to get more information about the battery, including the number of charging cycles. However, on new Xiaomi models (starting with the Redmi Note 10 and Mi 11), this method is often blocked by the manufacturer.

Instructions:

1. Open the Phone app.
2. Enter the combination: ##4636## (no spaces).
3. Select the Battery Information tab.

In this menu, pay attention to the following parameters:

If you see N/A instead of numbers, or if the menu doesn't open, the manufacturer has blocked access, and then move on to the next way.

Method 3: ADB commands are the most accurate method

The Android Debug Bridge (ADB) tool allows you to get full battery information, including hidden options that are not shown in the standard interface.This method works on all Xiaomi models, but requires a connection to a computer.

What you need:

• 🖥️ Computer with Windows, macOS or Linux.
• 📱 USB-cable (preferably original).
• 🔧 Utility. ADB (You can download from the official Android website).
• ⚙️ Included debugging by USB phone-on.

Step-by-step:

1. Activate Developer Mode: Go to Settings → About Phone. Click 7 times on MIUI Version until the notification “You’ve become a developer” appears. Return to Settings → Additional → Developer and enable USB Debugging.

Connect the phone to your computer and confirm the debugging permission.

cmd

Terminal

ADB

adb shell dumpsys battery

In the conclusion of the command, find the lines:

• charge_counter: X = number of charging cycles (if supported).
• Capacity: X is the current capacity in μAh (divided by 1000 to get mAh).
• Health: X is the battery state (e.g. 2 means “good”).

Install Xiaomi drivers on PC|Download Platform Tools with ADB|Enable the developer mode|Connect your phone to the original cable|Allow debugging by USB-->

If the dumpsy battery command does not show charge_counter, Try an alternative command for devices on Qualcomm:

adb shell cat /sys/class/power_supply/battery/cycle_count

On some models (e.g., POCO F3 or Redmi K40), the cycle counter may be stored elsewhere, and the command will help:

adb shell cat /sys/class/power_supply/bms/cycle_count

💡

If the ADB doesn't show the number of cycles, it doesn't mean there aren't any. The manufacturer could have hidden the data in another system file or blocked access.

Method 4: Third-party applications – AccuBattery, CPU-Z, and others

If you don't want to mess with ADB, you can use third-party utilities, which don't always show you the exact number of cycles, but they give you an idea of how much battery wear and capacity it actually is.

Top.-3 apps:

1. AccuBattery (free, with premium features) 📊 Shows the real battery capacity and percentage of wear. ⚡ Tracks the charging/discharge rate. 🔄 Estimates the number of cycles based on the charging history (not an accurate meter, but close to reality).
2. CPU-Z (free-for-free) 📋 Battery Tab Shows Health, Capacity and Technology. 🔍 There is no direct cycle counter, but you can compare the current capacity with the passport.
3. Battery Guru (paid but with trial period) 📈 Builds discharge and charging schedules. 🔋 Charge Cycles (on some models Xiaomi works correctly).

Importantly, these applications don't read the system cycle counter directly, but instead calculate it based on charging data, so they can be 10 to 20 percent different from the real thing. Use the combination of ADB and one of these applications for accuracy.

💡

AccuBattery requires 2-3 full charge/discharge cycles after the first installation so that the application collects enough data for accurate calculations.

Method 5: Reading data via MTK Engineer Mode (for Mediatek)

If your Xiaomi smartphone is powered by a Mediatek processor (such as the Redmi 9A, POCO M3 or Redmi Note 8T), you can use the MTK Engineer Mode app to access hidden battery data.

Instructions:

1. Download and install MTK Engineer Mode from Google Play.
2. Open the app and go to the MTK Settings section.
3. Select Battery Information.
4. Note the parameters: Battery Charge Cycle is the number of cycles. Battery Health is the percentage state. Battery Temperature is the temperature.

Some MIUI firmware may have limited access to this data. If the application doesn't show cycles, try:

• 🔹 Restart the phone and try again.
• 🔹 Install an older version MTK Engineer Mode (for example, 2019).
• 🔹 Use it. ADB (Method 3).

Warning: Do not change any settings in the MTK Engineer Mode unless you are sure of their purpose.Incorrect settings can damage the power controller or even fire the battery.

What to do if the cycle counter resets or shows incorrect data

Sometimes, after a firmware, settings reset, or battery change, the cycle counter is reset or starts showing incorrect values, which is because the data is stored in the EEPROM of the power controller, which can be reset by serious manipulation of the system.

Possible causes and solutions:

If you recently replaced the battery, the cycle counter will start counting again. That's okay, because the new battery has its own controller, but if the battery is used, the actual wear and tear may be higher than the meter indicates.

💡

After replacing the battery in an unofficial service, the cycle counter may show incorrect data. To avoid this, require the wizard to “prescribe” the new battery through special software (for example, Xiaomi Battery Tool).
