Battery module does not find /sys/class/power_supply/BAT0/charge_full

[xdnicoco]

I get an Error in block 'battery': failed to open file /sys/class/power_supply/BAT0/charge_full when trying to add a battery block. Using arch linux 4.13.7-1-ARCH on lenovo yoga 700. Result of ls -l /sys/class/power_supply/BAT0:

It should default to capacity, which you have...

[atheriel]

Having the same issue here, too. I have a capacity file but no charge_full file.

[Razakhel]

Still same issue here, charge_full not found:

$ ls /sys/class/power_supply/BAT0/
alarm     capacity_level  device       energy_full_design  manufacturer  power      present        status     technology  uevent              voltage_now
capacity  cycle_count     energy_full  energy_now          model_name    power_now  serial_number  subsystem  type        voltage_min_design

Using the custom block with the command given in issue #16 works great though.

command = "echo  `cat /sys/class/power_supply/BAT0/capacity`%"

@Razakhel do you mind me asking what kernel version you are running? I've had this issue on 4.11 but not since.

[Razakhel]

I'm on Arch, so I have the latest possible kernel version I guess. This has been updated yesterday so I don't know what its version was, but as of now I run on 4.14.9-1-ARCH and the bug is still there.

[atheriel]

Ok, I think that this is common and annoying enough that we should modify the logic.

I had the same problem, but also energy later disepaired and was replaced with charge.
