i3status doesn't distinguish between Idle and discharging battery.

[adippl]

At some point i3status on my computer stopped correctly displaying battery status while battery is idle. It is a really annoying bug.
I'm using gentoo linux.

I've looked into the code and discovered that i3status treats Discharging and Not charging states the same way.
Could you please considering merging this small patch to fix it?
This is small change causes i3status to display status_unk string when battery state is detected as Not charging

I get the same issue on a ThinkPad X1 Nano:

$ cat /sys/class/power_supply/BAT0/status    
    
Not charging 

My other devices seem to only use the unknown status.

Would appreciate a bugfix for this.

I currently have i3status installed on 3 lenovo laptops: x270, T550, T480
All 3 laptops use Not charging state.

Example with dual batteries:

$ grep -n "" /sys/class/power_supply/BAT*/status
/sys/class/power_supply/BAT0/status:1:Not charging
/sys/class/power_supply/BAT1/status:1:Charging

Some time ago I run into this, too, and created #486. It adds another status and prints 'IDLE' when a battery is reported as "Not charging" by the driver. I've just rebased it to current main. If you like you could give it a try.
