What to do if the device can search for the Redmi Buds 6 Lite but cannot connect to it?

It can be due to abnormal Bluetooth data on the phone. Try deleting the previous connection records on the device or resetting the Redmi Buds 6 Lite. Place the earbuds in the charging case with sufficient power and close the lid for 60 seconds. Then, open the lid and press and hold the button for 10 seconds until the indicator on the charging case flashes 3 times, then release it and use the device to search for earbuds to pair.
Note:
To delete the Bluetooth records on the phone, go to the [Settings] APP on the phone >> select [Bluetooth] >> [Redmi Buds 6 Lite] >> tap the [Unpair] icon at the bottom.
