To test your Xiaomi device’s battery health, use built-in diagnostics like *#*#6485#*#* for battery metrics or navigate to Settings > Battery > Battery health. Third-party apps like AccuBattery or CPU-Z provide detailed analysis. For advanced users, ADB commands or voltage testing tools offer hardware-level insights. Always calibrate the battery after testing for accurate long-term tracking.

How to Interpret Voltage Fluctuation Patterns?
Healthy Xiaomi batteries show:
- 3.7V (nominal) to 4.4V (full charge)
- Stable discharge curve under load
Warning signs:
- Voltage drops >0.5V when launching camera
- Rapid 100%→15% drops indicating dead cells
Voltage readings should maintain consistency across temperature ranges. At 25°C, a healthy battery loses 0.02V per hour during standby. When gaming at maximum brightness, expect 0.15-0.3V drops temporarily. Persistent low voltages (<3.4V) at 40% charge indicate advanced battery wear. Use Xiaomi's diagnostic codes during different usage scenarios:
| Activity | Acceptable Voltage Drop | Critical Threshold |
|---|---|---|
| Video playback | 0.1-0.2V | 0.35V |
| 5G browsing | 0.2-0.3V | 0.45V |
| Camera usage | 0.3-0.4V | 0.55V |
“Xiaomi’s Li-Po batteries typically withstand 800-1000 cycles before hitting 80% health. However, MIUI’s aggressive background task killing skews software readings. Always validate through multiple methods—I recommend cross-checking AccuBattery data with ADB’s
