Description

From the listing uploaded by “appupdater”.

1. What are the weaknesses of the Bluetooth headset? Bluetooth headsets are becoming more and more popular, because there is no wire, users can enjoy music anytime, anywhere, very convenient. However, Bluetooth headsets use rechargeable batteries, so they need to be recharged frequently. 2. What is Bluetooth Battery Saver? The Bluetooth Battery Saver is a simple widget that forces the Bluetooth headset to work in mono mode, saving battery drain and making playback longer. 3. Does Bluetooth Battery Saver really work? * In mono mode, the amount of wireless data transmission will be reduced (from 328kb/s to 192kb/s), and the consumption of the RF receiver will be less. * In mono mode, less data needs to be decoded, and the DSP load of the Bluetooth headset will be less. 4. Does Bluetooth Battery Saver affect sound quality? Yes, the stereo sound quality is converted to mono sound quality, which is a trade-off of play time and playback effect. 5. How to use Bluetooth Battery Saver * Click "Check Bluetooth Power Mode" to list connected device. * Click "Current Power Mode" to change mode to "Battery Saving" or "Normal".
