Battery Charge display not working

[mztikk]

Battery Charge is not being displayed in status bar, running the battery.sh also gives following errors

Use of uninitialized value $bat_state in pattern match (m//) at .config/i3/scripts/battery.sh line 46.
Use of uninitialized value $bat_state in concatenation (.) or string at .config/i3/scripts/battery.sh line 47.

After switching back to this version https://github.com/endeavouros-team/endeavouros-i3wm-setup/blob/3c7ced74922a4116bbec21a44d20687c0abefdb3/.config/i3/scripts/battery.sh it works again

@mztikk I created pull request. Could you please confirm, that upower -i /org/freedesktop/UPower/devices/battery_BAT0 returns no data on your PC? Also probably you are using variable env BLOCK_INSTANCE to set value and you get information for other battery then 0.

Hii @killajoe
I am having the same problem. I tried finding solution for this on internet but as I don't have much shell scripting knowledge I couldn't find anything relevant to it. Is there any update on this issue.

Hello @k2s
I tried your script but it is still not working for me.

output of shellscript

Use of uninitialized value $bat_state in pattern match (m//) at .config/i3/scripts/battery.sh line 53.
Use of uninitialized value $bat_state in concatenation (.) or string at .config/i3/scripts/battery.sh line 54.

I also ran the upower -i /org/freedesktop/UPower/devices/battery_BAT0 command on my PC it gave this output.

@HarshalRathore

• make sure you have upower installed
  • the original code, which works for you, was using acpi for the new one requires upowe
• if some other battery number (see ?) works in upower -i /org/freedesktop/UPower/devices/battery_BAT? then it is possible to set this number by adding BLOCK_INSTANCE=? to your i3blocks.conf
