How to Check Battery Health on Xiaomi Phones (MIUI Hidden Menu Guide)

 The battery is one of the most critical components of any smartphone. Over time, it naturally degrades, affecting performance, charging speed, and overall usability. If you’ve noticed your Xiaomi, Redmi, or POCO device draining faster than usual, or if you simply want to monitor its condition, MIUI includes a hidden diagnostic menu that lets you check battery health, capacity, and charge cycles — all without installing third-party apps.

In this detailed guide, we’ll explain why battery health matters, how to access MIUI’s hidden battery menu, how to interpret the data, and tips to prolong your Xiaomi battery life.

🔹 Why Checking Battery Health Matters

Modern Xiaomi devices use lithium-ion batteries, which degrade gradually with use. Some key points to understand:

  • Charge cycles matter: One full charge cycle equals a full 0% → 100% charge. Over time, repeated cycles reduce maximum battery capacity.

  • Performance impact: A degraded battery may lead to faster battery drain, unexpected shutdowns, or slower charging.

  • Proactive replacement: Knowing your battery’s condition helps determine when to replace it before issues become critical.

Checking your battery health regularly can save you from performance issues and ensure your Xiaomi device lasts longer.

🔹 How to Access the Hidden MIUI Battery Menu

MIUI has a built-in hidden menu that provides detailed technical information about your device’s battery. Follow these steps to access it:

  1. Open the Phone app on your Xiaomi, Redmi, or POCO device.

  2. Dial the hidden code:

    *#*#6485#*#*

  3. A new screen appears with various technical codes. These codes give you a complete overview of your battery’s health, charge cycles, and real capacity.

💡 Note: This menu is hidden for a reason. Be careful not to change settings if you don’t understand their function.

🔹 Key Codes and What They Mean

Here’s a breakdown of the most important battery codes in MIUI’s hidden menu:

CodeDescription
MB_06Current battery health status. If it shows “Good”, your battery is in proper condition.
MF_02Total number of charging cycles since the battery was first used. High numbers indicate aging.
MF_00Real battery capacity as a percentage of the original rated capacity. Helps detect degradation.

By interpreting these values, you can assess whether your battery is healthy, moderately degraded, or in need of replacement.

🔹 How to Interpret Battery Health Data

Understanding the hidden codes is crucial to making informed decisions:

  1. MB_06 = Good:

    • Your battery is functioning normally.

    • No immediate action is needed, but monitoring over time is recommended.

  2. MF_02 (Charge Cycles):

    • Batteries typically start losing efficiency after 300–500 full charge cycles.

    • If MF_02 shows 600–800 cycles or more, expect gradual degradation.

  3. MF_00 (Real Capacity):

    • 100% = Full original capacity.

    • Values below 80–85% indicate significant wear; consider replacement for optimal performance.

💡 Tip: Even if MB_06 shows “Good”, high cycle counts or low MF_00 values can explain faster drain or unexpected shutdowns.

🔹 Additional Tips for Maintaining Xiaomi Battery Health

Checking battery health is just one part of keeping your phone in top shape. Follow these practices to prolong battery lifespan:

  1. Avoid 0–100% full discharges:

    • Lithium-ion batteries perform best when charged between 20–80%.

    • Full discharges and overcharging reduce long-term capacity.

  2. Use the original charger:

    • Xiaomi’s fast chargers optimize voltage and prevent overheating.

    • Third-party or low-quality chargers can harm battery health.

  3. Limit high-temperature exposure:

    • Heat accelerates battery degradation. Avoid leaving your phone in direct sunlight or inside hot cars.

  4. Enable MIUI Battery Saver Features:

    • Go to: Settings → Battery & performance

    • Activate Battery Saver or Adaptive Battery to extend lifespan.

  5. Monitor Apps and Background Usage:

    • Excessive background apps increase heat and drain cycles.

    • Use MIUI’s Battery & performance → Manage apps battery usage to optimize.

🔹 Common Questions About Xiaomi Battery Health

Q1: Can I check battery health without the hidden code?

Yes, some third-party apps like AccuBattery can estimate health, but the MIUI hidden menu gives more precise system-level data.

Q2: Does MIUI show exact battery capacity in mAh?

No, it shows real capacity as a percentage of the original capacity. You can estimate actual mAh based on your model’s rated capacity.

Q3: Will battery replacement reset the cycle count?

Yes. Installing a new Xiaomi battery resets MF_02 to 0 cycles, restoring original capacity and lifespan.

🔹 Summary: Xiaomi Battery Health Check

To check the battery health and charge cycles on Xiaomi, Redmi, or POCO devices:

  1. Open the Phone app.

  2. Dial:

    *#*#6485#*#*

  3. Review the key codes:

    • MB_06 → Battery health (Good / Replace)

    • MF_02 → Charge cycles

    • MF_00 → Real capacity %

Tips:

  • Replace the battery if performance drops or charge cycles are high.

  • Follow best practices to prolong battery lifespan.

  • Regularly monitor health to prevent unexpected shutdowns or fast draining.

This hidden MIUI feature gives you a quick and reliable way to monitor battery health, ensuring your Xiaomi smartphone performs at its best for years.
