--- Comment #3 from ratijas <m...@ratijas.tk> ---
Since Bluetooth devices are part of the real world, and as we know the real
world is all messed up beyond recognition, things may get weird with some
devices.
For example, I happened to have a Sony WH-1000XM4 headset, and it reports its
battery percentage kinda fine but only in increments of 10%. I never knew
before that there is such a flag UP_DEVICE_LEVEL_NONE in Bluetooth, so now I
went to check it in the headphones. And nope, it's not there, even though they
only report their approximate value:
Device: /org/freedesktop/UPower/devices/headset_dev_[[REDACTED]]
native-path: /org/bluez/hci0/dev_[[REDACTED]]
model: WH-1000XM4
serial: [[REDACTED]]
power supply: no
