Why is the REDMI Note 14's activation time different from the battery usage time?

Thank you for your support of Xiaomi products. The differences in activation time and battery usage time, as well as changes after an OTA upgrade, are due to compatibility adjustments with newly added features.
For your reference, the detailed explanation is as follows:
1. The newly introduced features for displaying activation and battery usage times had initial compatibility issues, leading to discrepancies between the two times;
2. The OTA upgrade corrected these discrepancies, ensuring that the recorded activation and battery usage times align more accurately with system operations;
3. The activation time now reflects the correct first-time use. The updated battery usage time is based on the latest system calibration. Please rest assured that these updates do not impact device functionality.
