This will require changes in UPower, so that it doesn't try to access the Logitech unifying devices via user-space, and uses the data from the kernel. Did you already file a bug? Note that this would also mean losing the "lux" information, but I don't think that's something we're that interested in exposing. For example, for a keyboard that recharges via solar panels, at night: Device: /org/freedesktop/UPower/devices/keyboard_0003o046Do4002x0004 native-path: /sys/devices/pci0000:00/0000:00:14.0/usb3/3-10/3-10:1.2/0003:046D:C52B.0003/0003:046D:4002.0004 vendor: Logitech, Inc. model: K750 serial: 197F3F23 power supply: no updated: Fri 08 Jul 2016 01:17:40 CEST (95 seconds ago) has history: yes has statistics: no keyboard present: yes rechargeable: yes state: discharging warning-level: none luminosity: 16 lx percentage: 89% icon-name: 'battery-full-symbolic'
