BlueBatt allows you to read the battery level of most Bluetooth headphones, earphones, speakers, and Bluetooth Low Energy (BLE) devices. You can also retrieve other information, such as connection status, from most Bluetooth devices. It is possible to pair new devices and unlink others that are already associated. You can do all of these things in a moment with a very simple experience.
