Using `/sys/class/power_supply/*/capacity` instead of `charge_now`

Bug

In recent Linux releases, the /sys/class/power_supply/*/charge_now file no longer exists. I don't seem to find a corresponding article, but seeing https://docs.kernel.org/power/power_supply_class.html#attributes-properties.

We can tell that file was probably reduced to remove confusion, as charge_* are meant to contain capacity in µAh only.

Eitherway, currently this fails at:

FileNotFoundError: [Errno 2] No such file or directory: "/sys/class/power_supply/BAT0/charge_now"

Battery-Jarvis/batteryJarvis.py

Lines 23 to 31 in 7168b30

    
           charge_now_file="/sys/class/power_supply/"+folder+"/charge_now" 
        
           charge_full_file="/sys/class/power_supply/"+folder+"/charge_full" 
        
           charge_status_file="/sys/class/power_supply/"+folder+"/status" 
        
           charge_now=open(charge_now_file) 
        
           charge_full=open(charge_full_file) 
        
           charge_status=open(charge_status_file) 
        
           charge_now_content=charge_now.read()

Solution

Using /sys/class/power_supply/*/capacity if /sys/class/power_supply/*/charge_now is not found.

Also when battery is 100 % my charge status is "full" instead of "charging" .

BAT0 can be BAT1

in some system battery can be at BAT1 instead of BAT0
