Title:
[regression][bionic] Bluetooth keyboard battery reports 0%
Status in bluez package in Ubuntu:
Invalid
Status in linux package in Ubuntu:
New
Bug description:
I've recently upgraded to 18.04 from 17.10 and after the upgrade "upower -d"
reports always 0% as battery percentage of the bluetooth Logitech K810
keyboard.
Which is a bit annoying since I get a KDE warning on the battery.
Device: /org/freedesktop/UPower/devices/keyboard_hid_34o88o5do5eo0co2f_battery
native-path: hid-34:88:5d:5e:0c:2f-battery
model: Logitech K810
power supply: no
updated: Fri 04 May 2018 09:20:43 AM CEST (51 seconds ago)
has history: yes
has statistics: yes
keyboard
present: yes
rechargeable: yes
state: unknown
warning-level: none
percentage: 0%
icon-name: 'battery-missing-symbolic'
My guess is that the issue is in the bluetooth rather in the upowerd
since the reporting in the /sys/devices shows battery level of 0
