How to identify and reduce the occurrence of background APP removing while using the Xiaomi Smart Band 9?

To determine whether the APP has been removed in the background by the system, please refer to the following operation:
1. If the Mi Fitness APP has been removed in the background, reopening it will follow these two steps: first, display the APP launch page, then display the APP's homepage;
2. If the Mi Fitness APP has not been removed in the background, reopening the APP will resume the previous operation before exiting.
To reduce the frequency of being removed in the background during normal usage, consider the following two points:
1. Ensure sufficient battery power to avoid overheating of the phone and disable low-power mode. Insufficient battery power, severe overheating or running the phone in low-power mode will significantly increase the frequency of background APP termination;
2. Open [Settings] >> [General] >> [Background APP Refresh] on your phone and enable this feature.
