Problem phenomenon:
After the phone is connected to Bluetooth and turns on high-quality audio (LDAC decoding), the transmission distance is closer than SBC
Solutions:
Since the audio quality of SBC is relatively low, the amount of data transmitted at the same time is smaller than that of high-quality audio such as LDAC so, the distance that can be transmitted is relatively long and the communication quality can be guaranteed.
High-quality audio such as LDAC has high quality and the data transmitted at the same time greatly increases, requiring greater bandwidth so, a short transmission distance is required to ensure signal strength. When you use a Bluetooth device that is far away from your phone, it is recommended that you click the "i" on the right side of the paired device in Settings > Bluetooth to enter the paired device interface and turn off high-quality audio to ensure communication quality.
