Battery block broken on Arch

[byezy]

Just started using i3status-rs, great utility.

Have been able to get all blocks of interest working as advertised except battery. Flat out can't get the battery block to work. Battery data is working with i3status fine but I'm unable to get anything reported using i3status-rs (except charge status?).

The block is being evaluated as expected, for example disabling the icons.overrides section shows the battery icon rather than |F| . There is just no state/numbers output.

Have tried with all block defaults, have tried with explicit format and device. No luck. Bug? Documentation lag? MOST LIKELY Something dumb I'm doing? I would really like to get to the bottom of this as I run Arch on a laptop and definitely want to keep using i3status-rs.
