3. Wait for the Menu to Appear: After entering the code, the hidden menu should appear automatically. If it doesn't, try pressing the call button. The menu might take a few seconds to load, so be patient.
4. Interpret the Battery Information: Once the menu appears, look for specific codes to understand your battery health:
   • MB_06: This indicates the battery health status. "Good" means your battery is in good condition.
   • MF_02: This shows the date of manufacture, which can help you estimate the battery's age.
   • MF_05: This displays the battery's serial number.
   • MF_06: This indicates the battery model.
   • MB_00: This indicates the battery temperature.
   • MB_01: This indicates the battery voltage.
   • MB_07: This is one of the most important values, indicating the current battery capacity (in mAh).
   • MB_06: This indicates the battery health status. "Good" means your battery is in good condition.
5. Analyze the Results: Compare the MB_07 value (current battery capacity) with the original battery capacity specified by Xiaomi for your phone model. This will give you an idea of how much the battery has degraded over time. For example, if your phone originally had a 4000mAh battery and the current capacity is around 3200mAh, it means your battery has lost 20% of its capacity.
