If the Redmi Watch 5 fails to connect after being restored to factory settings, please refer to the following details:
1. In disconnected status, unbind on the APP side, the watch does not restore to factory settings, and needs to be restored to factory settings before the next binding, otherwise it cannot be paired with a new phone;
2. After the iOS phone is connected to the watch and the watch is restored to factory settings, the iOS phone system Bluetooth will try to reconnect to the watch, and the new phone will not be able to search for the watch (the iOS phone and the watch will be disconnected all the time, and the new phone cannot search during the connection period; during the disconnection interval, the new phone is just in scanning mode and can search). You need to enter the Bluetooth of the old iOS phone, find the corresponding connected device, and forget this device. At this time, use the new phone to search and pair the connection;
3. After the Android phone is connected to the watch and the watch is restored to factory settings, the Mi Fitness APP will reconnect to the watch and prompt you to delete the device or add. At this time, the new phone cannot search for the device. Delete the device on the old phone and search and connect the watch on the new phone.
