Bluetooth by Audio (Battery)

Are you short on battery life-span? Do you use a Bluetooth headset/speaker? Do you find yourself manually turning Bluetooth on/off?



This app will enable Bluetooth as long as an app requests audio focus (which means it's about to make a sound).
On my smart watch, it meant saving a lot of battery while allowing me to use my Bluetooth headset. My ROM doesn't even let me manually turn the Bluetooth on when a call is incoming.

Just turn on your Bluetooth headset when someone calls or before calling, or before you start listening to music.
The device will activate Bluetooth and within around 1 second it will connect to the headset, and start playing from there.

Why a notification? Android often kills background services that don't display a notification because it thinks they are not constantly needed. Since this app is mostly required when the device is most stressed, we'll need that to keep the service alive.

Does it consume battery running all the time? No. All this app has is a sleeping service, waiting for applications to request audio focus. It does not do anything while it waits, the operating system will wake it as soon as it's needed.
