Public bug reported:
The battery percentage reported by upower for Logitech devices connected
using Unify receiver are wrong. Below are the results for two devices:
Mouse and Keyboard:
* Battery percentages reported by Unify receiver using Solaar:
$ solaar show | grep -iP "^(( \d: )|(.*batt.*))"
1: Wireless Keyboard K270(unifying)
4: BATTERY STATUS {1000}
Battery: 70%, discharging.
2: Wireless Mouse MX Master
7: BATTERY STATUS {1000}
Battery: 20%, discharging.
* Battery percentages reported by upower:
$ upower -i /org/freedesktop/UPower/devices/keyboard_hidpp_battery_0
native-path: hidpp_battery_0
model: Wireless Keyboard K270

Basically the difference is big so I'm getting a lot of notifications
related to low battery even if the battery is OK:
* Mouse, upower: 10% real (Solaar): 20%
* Keyboard: upower: 70% real (Solaar): 55%
