Error when using battery module on Android Termux: Error in 'StarshipRoot' at 'battery': Unknown key

[nikelborm]

Current Behavior

On my notebook, I have starship installed.
It works without any warnings.
I copied notebook's config into Termux on my Pixel 4 XL.
And after that when I login it shows such warning (and battery percentage indicator doesn't work)

[WARN] - (starship::config): Failed to load config value: Error in 'StarshipRoot' at 'battery': Unknown key

Phone's prompt does not have battery info

u0_a291 in 🌐 localhost in ~ on 🌱 main 
❯ 

Expected Behavior

When I login on termux, warning does not show up and in my prompt I see my battery percentage as on my notebook:

~ on 🌱 main 
💀97% ❯ phone

Motivation for this is when users don't have direct or easy access to their phones, and they log into their phones via ssh to see some info like battery charge percent.

Possible Solution

Termux has the solution to use android APIs from CLI present as termux-api package:

I think this is going to be because the version you are using on your phone has been compiled without support for the battery module (this is an optional feature).

edit yep this has been removed in the termux package because the battery crate doesn't support termux.
