[Feature Request] Extended Battery support, like charging?

[LeeNX]

Possible add GATT Battery Status (0x2A1A) and Battery Level State (0x2A1B)

On the Bluetooth SIG page, https://www.bluetooth.com/specifications/specs/battery-service/ there is a release for Battery Service 1.1

Which includes some items that might be worth adding, if we want the host to know if the gamepad is charging or other battery health/service properties. It's more a UX thing, but I can see the gamepad been charged, while in use.
