Smart watches cannot receive information when they leave the APP interface. What happened?

The notice on the bracelet is not displayed on the information screen of the mobile phone because the mobile phone has turned on the power saving mode, or the information screen automatically cleans up the background program.

In this case, Xiaomi's health application was cleaned up, so the bracelet could not receive any information. Therefore, it can be set as background protection and included in the protection white list.
