Where to see the battery status on Xiaomi: step-by-step instructions and secret codes

The battery is one of the most vulnerable components of a smartphone, and Xiaomi owners often face the question: how to check its real state? Over time, the battery loses capacity, discharges faster, and the device begins to suddenly turn off even at 20-30% charge. Fortunately, MIUI offers several methods of diagnosis, from built-in tools to hidden engineering menus.

In this article, you will find 5 proven methods to find out how to wear a battery on Redmi, POCO or Mi – from standard settings to professional utilities like AccuBattery. We will also analyze which indicators are considered normal and when it is time to think about replacing a battery.

1. Standard method: the menu "Battery status" in MIUI

The easiest method is to use the built-in MIUI statistics. It is suitable for all modern Xiaomi smartphones (from Redmi Note 10 to Xiaomi 14) and does not require the installation of additional applications.

1. Open the settings → Battery and performance.
2. Slap the gear icon (⚙️) top-right.
3. Select the battery status.

Here you will see three key parameters:

• 🔋 Current capacity is the actual battery capacity per mAh (e.g., 4,800 out of 5,000 mAh).
• ⚡ Charging cycles: how many times the battery has been 100% charged, up to 500 cycles.
• 📉 Wear is the percentage of capacity loss. Up to 20 percent is considered acceptable.

💡

If you don't have Battery Status, upgrade MIUI to the latest version, which may not be available on older firmware (MIUI 11 and below).

⚠️ Note: On some models (e.g, POCO F3 or Redmi 9T) Instead of accurate numbers, you can display a general message like "Good condition", which means that wear is less than 15.

2. Hidden engineering codes for battery diagnostics

If the standard menu doesn't give you enough information, you can use service codes. They work on most Xiaomi devices without root rights, but some operators can block them.

After entering the code ##4636##, select Battery information.

• 🔢 Level - current charge in percentage.
• 🔌 Voltage - voltage (normal: 3.7-4.2 V for Li-Pol).
• 🌡️ Temperature – Temperature (optimum: 25–40)°C).

⚠️ Warning: If you have a "Connection problem" message after you enter the code, your operator has blocked access. INFO ★Samsung★ (It also works on Xiaomi).

3. Detailed analysis applications: AccuBattery and AIDA64

Third-party utilities provide deeper analytics than built-in MIUI tools. We recommend two proven applications:

1. AccuBattery (free, with premium options)

• 📊 Shows real capacity (compared to passport).
• 🔄 Tracks charging cycles and wear rate.
• ⚡ Gives recommendations for optimal charging (for example, do not keep on 100%).

2. AIDA64 (paid version)

• 🔧 Shows battery technology (Li-Ion/Li-Pol).
• 📅 Displays the date of battery production.
• 🌡️ Monitoring the temperature in real time.

⚠️ Warning: Once you install AccuBattery, you need 2-3 full charge-discharge cycles for precise calibration. Don’t delete the app right away – wait until it collects enough data (usually 1-2 days).

4. Verification through ADB: for advanced users

If you want the most accurate data, you can use ADB (Android Debug Bridge), which is suitable for tech-savvy users and requires a computer.

1. Turn on USB Debugging in Settings → About Phone → MIUI version (shap 7 times, then go back to Additional Settings → For Developers).
2. Connect your phone to your PC and start the command: adb shell dumpsys battery
3. Find the lines of capacity, voltage and temperature.

To check the actual capacity, use the command:

adb shell dumpsys batterystats

Look for the option com.android.internal.os.BatteryStatsImpl – there will be information about the energy consumption of applications.

⚠️ Attention: Use ADB It can cause failures if you type the wrong commands. Don't change the system settings of the battery through the adb shell - this can cause the battery to fail.

5. Physical Diagnostics: When to Bring to the Service

If software methods show critical wear (over 30%) but you doubt the accuracy of the data, look for physical signs of battery failure:

• 🔥 The phone overheats even with minimal load (for example, in messengers).
• 📉 Charge drops abruptly (from 50% to 15% in a few minutes).
• 🔌 The device does not turn on without charging, even if it shows 10-20%.
• 💥 The body swelled (seen by the gaps between the screen and the frame).

In such cases, a battery replacement is required. Xiaomi's official service centers use original batteries with a 6-month warranty.

• Redmi Note Series: 1,500–2,500 ₽.
• Xiaomi 11/12/13: 3 000–4 500 ₽.
• POCO F/X: 2 000–3 500 ₽.

💡

Never try to replace the battery yourself on models with adhesive attachment (such as Xiaomi 12 Pro) – this can damage the display plumes.

6.How to extend the life of the battery: 7 rules from Xiaomi

Even if the battery is in good condition, following simple guidelines will help slow down wear by 20 to 30 percent.

1. Avoid full discharge – charge your phone at 15-20% charge.
2. Don’t keep charging all night – turn off after 100% or use smart charging in MIUI.
3. Use the original chargers – cheap cables overheat the battery.
4. Update MIUI – new versions optimize power consumption.
5. Turn off 5G/LTE if the signal is weak (constant network search consumes charge).
6. Keep your phone at 40-60% charge if you don’t use it for a long time (e.g. in a warehouse).
7. Avoid extreme temperatures – do not leave your smartphone in the sun or in the cold.

⚠️ Attention: Quick Charging Function (33W/67W/120W) speed up the battery wear 10–15% If you don't need an emergency charge, turn it off in Settings. → Battery. → Fast charging.
