How to know the battery capacity on Xiaomi Redmi Note 10 Pro: all ways

The battery is one of the most vulnerable components of the smartphone, and the Xiaomi Redmi Note 10 Pro is no exception. Over time, its capacity inevitably decreases: after 300-500 charging cycles, you may notice that the phone discharges faster and the percentage of charge “jumps” unpredictable. But how to check how worn out the battery is? Official MIUI settings do not show the exact capacity in milliampere hours (mAh), but only the approximate percentage of wear — and then not on all firmware.

In this article, we will explore all the working ways to test the real battery capacity on the Redmi Note 10 Pro (sweet/sweetin models), including hidden engineering menus, specialized applications and even hardware methods. You will learn how to distinguish software wear from physical wear, why data may differ in different utilities, and what to do if capacity has fallen below a critical 80%.

1. Testing capacity through the engineering menu (no root)

The most reliable way to find out the real capacity of the battery is to look at Xiaomi’s engineering menu, which is hidden from ordinary users, but is accessible through secret code. Importantly, this method only works on the original MIUI firmware (including the global and Chinese versions), Castom firmware (such as LineageOS) can block access.

Instructions:

1. Open the phone application (call).
2. Enter the code: ##4636###.
3. In the menu that appears, select Battery Information.
4. Pay attention to the lines: 🔋 Level - current charge in percentage. 📊 Capacity is the actual capacity in mAh (for example, 4850/5020 means that 5020 There's a mh left. 4850). ⚡ Voltage - voltage (normal) 3.7–4.4 V).

⚠️ If you see the unknown or zeros instead of numbers, then:

• 📱 You have an unofficial firmware installed (e.g. Pixel Experience).
• 🔧 Manufacturer has disabled access to the engineering menu in your version MIUI (relevant to some regions).
• 🔋 The battery is not original (Chinese clones often don't transmit data).

💡

If the engineering menu doesn’t open, try entering the code through the Symbols app (preinstalled in MIUI) or use a third-party keyboard with * and # support.

2.Use of applications for battery diagnostics

If the engineering menu isn't available, third-party utilities will come to the rescue, analyzing data from the battery controller and showing capacity, temperature, voltage and even discharge history.

How to use AccuBattery (the most popular option):

1. Download the app from Google Play.
2. Charge your phone to 100% and calibrate (in the app settings, select Calibration → Start).
3. After 2-3 cycles of charging / discharging, open the Health tab - there will be a rating of capacity.

⚠️ Note: Apps without root rights show rated capacity, not accurate. For example, if AccuBattery writes "90% health", it does not mean that the battery has lost exactly 10% of capacity - the error can be as high as 15-20).

3. Checking through ADB (for advanced users)

If you're not afraid of the command line, you can get your battery data through ADB (Android Debug Bridge), which doesn't require root, but you need to install drivers and enable debugging over USB.

Instructions:

1. Turn on Developer Mode: Go to Settings → About Phone. Tap 7 times on MIUI Version. Go back to Settings → Additional → For Developers and activate USB Debugging.

adb shell dumpsys battery

• Capacity: X is the current charge in %.
• charge counter: Y is the remaining charge in μAh (divided by 1000 to get mAh).
• Health: Z is the battery state (e.g. 2 means “good”).

Example of conclusion:

Current Battery Service state:




AC powered: false




USB powered: true




Wireless powered: false




status: 2




health: 2




present: true




level: 85




scale: 100




voltage: 4023




temperature: 290




technology: Li-ion


  charge counter: 3850000 ← is 3850 mAh

⚠️ Note: The charge counter value can be reset after rebooting or turning off the battery. For accurate measurement, repeat the command at 100% charge and compare with passport capacity (5020 mAh for the Redmi Note 10 Pro).

4. Hardware inspection (multimeter or service center)

If the software methods show conflicting results, then there's hardware diagnostics, and you need it in three cases:

• 🔧 You suspect that the battery is swelling (visually the phone case is deformed).
• 📉 The phone turns off at 20-30% charge, although it shows normal capacity.
• 🔄 You bought a used Redmi Note 10 Pro and want to check the originality of the battery.

Methods of hardware verification:

1. Multimeter: Turn off the phone and remove the battery (if possible). Connect the probes to the battery contacts (red to +, black to -). Healthy battery voltage: 3.7-4.2 V. If below 3.5 V, capacity is critically low.
2. USB-Tester: Connect the tester between charging and the phone. Completely discharge and charge the phone, fixing the real capacity (in mAh).

Service centre:

• Xiaomi’s official services use professional analyzers (for example, Cadex C7400).
• The cost of diagnosis: ~ 500-1000 rubles.

⚠️ If you decide to remove the battery yourself, remember:

• 🔥 Risk of short circuit in case of incorrect contact handling.
• 🛠️ On the Redmi Note 10 Pro, the battery is glued to the screen – you need a mediator and a hair dryer to remove it (heating to 60-70).°C).
• ⚠️ Damage to the battery plume can disable the power controller (repair) ~3000-5000 rubles).

5. Battery calibration: when and how to do

If the capacity seems normal, but the phone suddenly turns off or "jumps" the percentage of charge, the problem may be in desynchronizing the battery controller.

How to Calibrate the Battery on Redmi Note 10 Pro:

1. Completely discharge the phone before automatically shutting down.
2. Connect the original charger and do not turn on the phone for 2-3 hours (even if the screen will appear 100%).
3. Turn off the charging, turn on the phone and wait for the full load.
4. Repeat the discharge / charging cycle 1-2 times.

⚠️ Note: Calibration does not restore capacity, but only corrects the readings of the controller. If the battery is physically worn out (capacity below 80%), calibration will not help - you need a replacement.

💡

Calibration should be done 1 time in 3 months or after updating MIUI. It is useless if the battery is swollen or the phone does not hold a charge for more than 2-3 hours.

6.What to do if the battery capacity is critically low

If the test showed that the battery capacity fell below 80% of the original (less than 4000 mAh for the Redmi Note 10 Pro), it is time to think about replacing.

Tips for choosing a new battery:

• 🔍 Buy only batteries with labels. MB-J11 (Original article for Redmi Note 10 Pro).
• 🛒 Avoid sellers with prices below 800 rubles – it is a guaranteed fake.
• 📦 Check to have a new thermal paste and insulation tape in the kit.

After the battery is replaced:

• 🔄 Make 2-3 full charge/discharge cycles for calibration.
• ⚡ Use only original or certified chargers (e.g. Xiaomi) 33W).
• 🌡️ Avoid overheating (do not play heavy games while charging).
