What to do if the Xiaomi Buds 5 Pro does not automatically reconnect when opening the charging case?

Please refer to the following methods to troubleshoot:
1. The Xiaomi Buds 5 Pro automatically reconnects to the last connected device by default. If the last connection is not your current cell phone, you need to reset the earbuds to reconnect the cell phone;
2. The phone is far away from the earbuds, more than the effective transmission distance (10m), or there are obstacles between the earbuds and the phone;
3. Make sure the Bluetooth of your cell phone is turned on. If Bluetooth is not turned on, please turn on Bluetooth manually;
4. Due to the special characteristics of the Bluetooth earbuds, the electromagnetic wave in your area will interfere with the Bluetooth connection, and the earbuds will be disconnected and can not automatically reconnect in time. Please move to another location to try.
