Why is the battery endurance of the Xiaomi Pad Mini poor after a system update or transferring data from an old device?

After a system update or when transferring data from an old device, the Xiaomi Pad Mini can experience higher-than-normal battery consumption. This is due to intensive CPU tasks such as app pre-compilation, data recovery, and background synchronization. These processes temporarily increase power usage, which can make battery endurance seem lower than usual. The battery will return to normal within 1–2 days once these tasks are completed.
This behavior is expected and ensures that your device fully updates and optimizes Apps and data for smooth performance.
