How to check the battery on your Xiaomi phone: all the ways from hidden menus to apps

Battery status is one of the key factors affecting performance and lifespan of a Xiaomi, Redmi or POCO smartphone. Even if your phone charges quickly and holds a charge all day, the actual battery wear can be 30-40%, which is already critical for durability. Unfortunately, the manufacturer does not display this information on the home screen, but it can be obtained in several ways, from built-in tools to third-party utilities.

In this article, we’ll break down all the current battery testing methods on Xiaomi devices, including hidden engineering menus, service codes, MIUI apps and third-party programs. You’ll learn not only how to view current wear, but also how to interpret temperature, voltage and charging cycles. And finally, practical tips on how to extend battery life by 20-30% without replacing.

1. Check through the hidden MIUI menu (no root)

The fastest way to know battery status is to use the built-in MIUI engineering menu, which is available on all Xiaomi, Redmi and POCO smartphones without having to install additional programs. Importantly, some menu items may differ depending on the firmware version (MIUI 12/13/14 or HyperOS).

Instructions:

• 📱 Open the phone application (calling).
• 🔢 Enter the combination: ##4636### (on some models it may not work – see the alternative below).
• 🔧 In the menu that opens, select Battery Information).
• 📊 Pay attention to the following points: Level - current charge level in %; Health - battery state (ideally - Good); Temperature - temperature in degrees (normal: 25-40°C); Voltage - voltage (normal: 3.7–4.4V).

If the menu doesn't have a Health item, it means your firmware doesn't support displaying it, so move on to the next one.

💡

If the battery temperature is above 45°C in normal use, it is a sign of overheating. Try removing the case, closing the background applications or checking the charger for compatibility.

2. Use of service code for diagnosis

For a deeper diagnosis, you can use a service code that displays advanced information about the battery, including the number of charging cycles and the actual capacity. This method works on most Xiaomi devices with Qualcomm Snapdragon processors (for example, Redmi Note 11 Pro, Xiaomi 12T, POCO X5 Pro).

How to check:

1. Open the Phone app.
2. Enter the code ##284## (on some models, ##6484##).
3. On the menu. MBB Information or Battery Find the Items: 🔋 Battery Charge Cycle – Number of charging cycles (normal up to 500); 📉 Battery Capacity – current capacity in mAh (compare with passport); ⚡ Charging Status (Not Charging, Fast Charging, etc.).

The critical capacity is less than 80% of the factory capacity, for example, if your Redmi Note 10 Pro was originally 5020 mAh and now it is 3800 mAh, the battery is worn out by 24% and needs to be replaced.

3.Security app – official method from Xiaomi

The manufacturer has built-in battery monitoring tool in the Security app, which is suitable for all devices on MIUI 12 and later, including HyperOS. The advantage of the method is that you do not need to enter codes or install third-party programs.

Step-by-step:

• 🛡️ Open the Security app (Icon with shield).
• 🔍 Go to Optimization or Battery (the name may be different).
• 📊 Click on Battery Health (Battery Health).
• 🔋 Percentage of wear (e.g. 88% means battery lost 12% capacity); Recommendations for extending service life; Temperature chart for last day.

If your Security app doesn’t have a battery partition, update it via Google Play or use an alternative method from the next section.

4. Third-party applications for detailed diagnostics

If the built-in MIUI tools don't give you the full picture, you can use specialized applications that show not only wear, but also charging history, discharge rate, real voltage, and even predict the remaining life, we tested 5 popular utilities and selected the best ones for Xiaomi.

Top.-3 applications:

For maximum accuracy, use AccuBattery for 2-3 days, and the app will collect data on your charging habits and give personalized recommendations, for example, it can show that your Xiaomi 13 Lite loses 10% of capacity due to frequent use of fast charging.

💡

Apps like AccuBattery not only show current wear, but also predict how long a battery will last for your use style, which helps you plan a replacement in advance.

5. Check through ADB (for advanced users)

If you're willing to spend 10-15 setup, ADB-The teams will give you the most accurate information about the battery, including data that even specialized applications don't show.

Instructions:

1. 💻 Install. ADB Tools on PC.
2. 📱 On the phone, turn on the debugging. USB: Settings → The phone. → Version. MIUI (press 7 times) Settings → Additionally. → For developers → Debugging by USB
3. 🔌 Connect your phone to your PC and type in the command line: adb shell dumpsys battery
4. 📋 Find the key parameters: health – state (2). = Good, 3. = Poor capacity: current capacity; voltage; technology: battery type (should be Li-ion or LiPo).

Example of output for POCO X3 Pro:

health: 2


level: 85




scale: 100




voltage: 4123 (mV)




temperature: 320 (32°C)




technology: Li-ion




Capacity: 4800 (mAh, originally 5160)

If the health parameter is 3 or 4, the battery is critically worn out and could fail in the coming months.

6. Physical examination and signs of battery wear

Even without special tools, you can suspect battery problems for indirect reasons. If your Xiaomi is behaving suspiciously, check for the following symptoms:

Alert signals:

• 🔋 The phone turns off when 20-30% charge (real wear and tear) >50%).
• ⚡ Charging is jerky or interrupted (problems with the battery controller).
• 🔥 The body warms up in the battery area even without loading.
• 📉 Working hours have been reduced by 30-40% compared to the new device.
• 💥 The battery swelled (seen on the raised screen or body).

If you notice at least 2-3 signs from the list, it is recommended to conduct a full diagnosis with one of the methods described above, or contact the service.

7.How to extend the life of the Xiaomi battery: 5 working tips

Even if your battery is still in good condition, following simple rules will help to keep its capacity on the market. 20-30% These recommendations are based on official Xiaomi guidelines and battery manufacturer research.

Rules of care:

• 🔌 Avoid deep discharge (below). 10%) and recharge (above) 90%). Optimal range — 20-80%.
• ⚡ Use original chargers or certified ones (with Quick Charge support for your model).
• 🌡️ Do not use your phone in temperatures below 0°C and above 35°C (for example, do not leave in the sun or in the car in winter).
• 🔄 If you don’t use your phone for a long time (such as a spare phone), keep it charged. 40-50% off.
• 📵 Turn it off. 5G, GPS background applications, if they are not needed - this reduces the load on the battery.

Compliance with these rules can extend battery life from standard 2-3 years to 4-5 years, especially on models with large-capacity batteries (for example, Redmi Note 12 Pro+ from 5000 mAh).

💡

The most common mistake users make is to keep their phone on charge all night, resulting in micro-recharges that reduce battery life by 15-20% per year.
