How to check the number of battery cycles on Xiaomi: all ways

The battery is one of the most vulnerable components of a smartphone, and its life depends on the number of charge cycles. Xiaomi, Redmi and POCO say that the lithium polymer batteries in their devices are designed for 400-600 full cycles until a noticeable decrease in capacity. But how do you know how many cycles your battery has already “worked”? This information will help assess the actual wear of the battery, plan a replacement or optimize charging to extend the life of the gadget.

Unlike Apple or Samsung, where charge cycle data is partially available in settings, Xiaomi does not provide this information out of the box. However, there are several proven ways to get it from hidden MIUI menus to specialized applications. In this article, we will analyze all current methods, including nuances for different models, and explain how to interpret the obtained numbers and what to do if the indicators are critical.

⚠️ Important: The number of charge cycles is not the same as the "percentage of battery wear" cycle is considered complete when the battery is discharged to 100% of its capacity (for example, twice 50 times each% = The actual wear depends on the depth of discharge, temperature and other factors.

1.What are charge cycles and why is it important

The charge cycle is the complete process of discharging and then charging the battery to 100%. For example, if you discharged the smartphone from 100% to 50% and then recharged to 100%, this will be considered half a cycle. Modern lithium polymer batteries in Xiaomi smartphones lose about 20-30% of capacity after 500 full cycles, but the real performance depends on the operating conditions.

Why is it critical to know that?

🔋 Replacement planning: if the cycles are already 700+, Battery can suddenly run out of 50% in an hour – better to prepare in advance.
💰 Evaluation of used device: when buying from hand, the number of cycles will show the real age of the battery (even if the case is as new).
⚡ Charging optimization: Knowing current cycles can help you adjust your habits (e.g. avoiding full discharge).

Xiaomi manufacturers don't advertise this information, but it's stored in the battery controller, and you can access it through an engineering menu, service codes, or third-party utilities, and then you can see the detailed instructions for each method.

📊 How often do you check the battery status?

Never.

Six months

Only when the problems start.

Before buying a used phone

The most reliable and versatile method is the use of the hidden MIUI engineering menu, which works on most Xiaomi, Redmi and POCO models (except for some budget devices on MediaTek).

Open the Phone app and enter the code: ##4636## Some firmware may run an alternative code: ##284###.
In the menu that opens, select Battery Information.
Find the lines: Charge counter (mAh); Battery capacity (current capacity); Battery health (if any).

Charge counter

250

⚠️ Note: On some devices (e.g. Redmi Note 10 Pro or POCO X3 Pro) the engineering menu may be blocked, in which case try alternative methods or use ADB (described below).

Charge your phone to at least 50%

Write down the nominal battery capacity (indicated on the box or in the model characteristics)

Connect to Wi-Fi (in case you need to download more data)

Have a calculator on hand to calculate cycles-->

Method 2: AccuBattery Application (for users without root)

If the engineering menu is not available, the third-party AccuBattery app (available on Google Play) will come to the rescue, and it doesn't show the number of cycles directly, but it allows you to estimate battery wear and indirectly calculate cycles based on charging statistics.

Install AccuBattery and provide all the permissions you request.
Charge your phone to 100% and wait for the app to collect data (usually 2-3 charge cycles are required).
Go to the Health tab and pay attention to the: 📊 Capacity assessment - comparison with nominal capacity. 🔄 Charge counter - total amount of charged energy (in mAh).

Divide the charge meter by the nominal battery capacity (for example, 4500 mAh) and multiply by 100 – get an approximate number of cycles.

Example: If AccuBattery shows a meter of 1,800,000 mAh and a battery of 4,500 mAh, then cycles ≈ 400.

⚠️ Limitations of method:

📱 The app does not show exact cycles, only indirect data.
🔄 Time is required to collect statistics (minimum 1-2 weeks of use).
🚫 On some devices (for example, with MIUI 14+) Access to battery data may be blocked.

💡

If AccuBattery doesn't show the charge counter, try calibrating the battery: completely discharge the phone before turning it off, then charge it to 100% without interruption, which sometimes helps wake the sensors up.

Method 3: Through ADB (for advanced users)

If the engineering menu is blocked and the apps don’t give you accurate data, you can use Android Debug Bridge (ADB), a method that requires a computer and minimal command line skills, but provides the most complete information.

Instructions:

Download and install ADB Tools on PC.
Turn on the phone Debugging over USB (Settings → About Phone → MIUI version – press 7 times, then go back to Additional → For Developers).
Connect your phone to your PC and type in the command line: adb shell dumpsys battery
Find the lines in the lead: charge_counter — Charge counter (similar to engineering menu). capacity - current capacity.

Critical information: On some Xiaomi devices (especially those with MIUI 13+), the dumpsys battery command may return incomplete data.

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

It works on parts of devices with Qualcomm chips (for example, Xiaomi 11T or POCO F3).

What if the ADB does not show cycles?

If none of the commands worked, it means that the manufacturer blocked access to the battery data at the firmware level, in which case there are two options: 1. Use root access (described in the next section). 2. Contact the Xiaomi service center - they have specialized diagnostic software.

5. Method 4: With root access (maximum accuracy)

If you're ready to get root rights, you can see the number of charge cycles in their pure form, which is a method that's suitable for enthusiasts, because it requires unlocking the bootloader and installing Magisk or SuperSU.
