How to find out the number of battery charging cycles on a Xiaomi smartphone: all working methods

Have you noticed that Xiaomi's smartphone has become more discharged, even though it used to hold a charge all day? Or are you planning to buy a used device and want to check the actual wear of the battery? The key parameter that will help you assess the state of the battery is the number of charge cycles measured in mAh (milliamp-hours). The higher this value compared to the factory capacity, the stronger the wear.

Unlike iPhones, where battery data is available in settings, Android smartphone manufacturers (including Xiaomi, Redmi and POCO) often hide this information. However, it can be obtained in several ways: through engineering menus, special applications, ADB commands or even a physical inspection of the battery. In this article, a full guide to checking charging cycles with a parsing of each method, including hidden nuances and typical errors.

1.What are charging cycles and why is it important

One charging cycle is a full battery discharge of 100% to 0% and a return charge of 100%. For example, if you discharged your smartphone today from 100% to 50% and tomorrow from 50% to 0%, it still counts as one full cycle. Modern lithium polymer batteries in Xiaomi smartphones are designed for 500-800 cycles to noticeable degradation (loss of 20-30% of capacity).

Why is it critical?

• 🔋 Battery capacity decreases with each cycle. After 500 cycles, a 4,000 mAh battery can only really deliver 3,000-3200 mAh.
• 📉 Fast discharge is the first sign of wear and tear. If a smartphone sits 15-20 percent in an hour on standby, the battery is close to being replaced.
• 💥 Bloating risk: batteries with lots of cycles (>800) are more likely to swell, especially when using non-original chargers.

Xiaomi's manufacturers don't advertise this information, but you can get it yourself, and then you can get it from all the working methods, from simple to advanced.

2. Check through the engineering menu (#4636##)

The quickest way is to use the hidden engineering menu available on most Xiaomi, Redmi and POCO smartphones. It doesn’t require root rights or additional apps.

Instructions:

1. Open the Phone app.
2. Enter the combination: ##4636### (on some models it may not work – see the alternatives below).
3. In the menu that opens, select Battery Information.
4. Note the lines: Level is current charge as a percentage. Health is battery status (if any). Capacity is current capacity in mAh (not all models show).

If #4636### doesn’t work, try the alternative codes:

• 📱 ##6484## - Battery test (on some Redmi Notes).
• 🔧 ##64663## - Hardware testing menu (includes battery data).

⚠️ Note: On new Xiaomi models (e.g. Xiaomi) 13/14, Redmi Note 12) The engineering menu may be blocked, in which case use the methods in the following sections.

Charge your smartphone at least 50% |

Record the factory battery capacity (indicated on the box or in the model characteristics)|

Connect to a stable Wi-Fi network (for alternative methods)|

Have a notebook on hand to record indicators-->

3. applications for battery testing (without root)

If the engineering menu isn't available, use third-party apps that analyze the battery sensor data and show the current capacity, voltage, temperature and approximate number of cycles.

Top.-3 tested applications:

How to use AccuBattery (the most accurate application):

1. Install and open the application.
2. Charge your smartphone to 100% and leave another 1-2 hours on charging (for calibration).
3. Go to the Health tab. It'll show up here: 🔋 Design capacity (in mAh) - compare with the factory. 🔄 Number of cycles (approximate). ⚡ Percentage depreciation.

⚠️ Note: Applications without root rights show approximate data. Access to system files is required for the exact number of cycles (see section on the system). ADB).

💡

If the app is 20 to 30 percent lower than the factory capacity, but the smartphone is holding the charge normally — maybe the battery sensors require calibration. Try to fully discharge and charge the phone 2-3 times in a row.

4. Check through ADB (for advanced users)

The ADB (Android Debug Bridge) method provides accurate battery data, including the number of cycles stored in system logs, requires a computer and minimal command-line skills.

Step-by-step:

1. Download and install ADB Tools on PC.
2. On your smartphone, turn on Developer Mode: Go to Settings → About Phone. Tap 7 times on MIUI Version. Go back to Settings → Additional → Developer. Activate USB Debugging.
3. Connect your smartphone to your PC via USB and confirm the debugging permission.
4. Open the command prompt (Windows) or terminal (macOS/Linux) in the folder with ADB.
5. Type in the command: adb shell dumpsys battery In the answer, find the lines: capacity - current capacity. charge counter - the amount of charge in microamp hours. To translate to mAh, divide by 1000. cycle count - the number of cycles (if supported).

Example of team withdrawal:

current now: 3500000 (mkAh = 3500 mAh)




charge counter: 7800000 (mkAh = 7800 mAh)




cycle count: 215

If the cycle count bar is missing, your Xiaomi model does not store this information in logs, in which case only a physical inspection of the battery (section 6) will help.

💡

ADB-The method is the most accurate, but it doesn't work on all Xiaomi models. If the team doesn't return cycle count, try an alternative command: adb shell cat. /sys/class/power_supply/battery/cycle_count

5. Check through MIUI Hidden Settings (hidden settings)

Some Xiaomi smartphones with MIUI firmware have a hidden MIUI Hidden Settings menu where you can find advanced battery information. This method works on Redmi Note 10/11, Xiaomi Mi 11 and later.

Instructions:

1. Download the MIUI Hidden Settings app.
2. Open the app and provide root rights (if any) or ADB permissions.
3. Go to the Battery section.
4. Find the parameters: Battery Capacity is the current capacity. Charge Cycles is the number of cycles (if available). Battery Health is the state as a percentage.

If the app doesn't show cycles, but there's a Battery Wear parameter, multiply it by 2, which is the approximate number of hundreds of cycles. For example, Battery Wear: 15% ≈ 300 cycles (15% × 2 × 100).

Physical inspection of the battery (for disassembly)

If the software methods don't work, you have to take the smartphone apart and look around the battery, which is suitable for advanced users or in preparation for a battery replacement.

What you'll need:

• 🔧 Set of screwdrivers (cross, flat, suction cup for the screen).
• 🔥 A hair dryer or plastic shoulder blade to separate the screen.
• 📸 Loupe or camera phone for taking small details.

How to check:

1. Turn off your smartphone and remove the tray for SIM-map.
2. Heat the screen edge with a hair dryer (no higher than 60°C!) and gently tuck it with a plastic spatula.
3. Disconnect the battery plume (usually it is under a protective film).
4. Check the battery: 🔍 Marking: the battery may be marked with the date of production (e.g, 2022-05-15). If the battery is older 2–3 years, its capacity is exactly below the factory. 📏 Bloating: if the battery is swelling (see by the curvature of the body), it urgently needs to be replaced. 🔢 Cycles: on some batteries (e.g. from Redmi Note) 9 Pro) may be a sticker with the number of cycles (rarely).

⚠️ Warning: Disassembling your smartphone is warranty-free and can damage your plumes or screen.If you're unsure of your skills, contact your service center.

Estimation of wear on indirect grounds

If none of the methods worked, evaluate the state of the battery on indirect grounds:

Signs of severe wear and tear:

• ⚡ Smartphone discharges by 10-15% in 30 minutes in standby mode.
• 🔥 Overheated when charging (above 40)°C).
• 🛑 Turns off at 10-20% charge (uncalibrated sensor).
• ⏳ Charging up to 100% takes more than 3-4 hours (with the original power supply).

What to do:

• 🔄 Battery calibration: fully discharge the smartphone before turning off, then charge to 100% without interruptions. Repeat 2-3 times.
• 🔧 Battery replacement: if the capacity has fallen below 70% of the factory, the battery should be replaced.
