It isn't that different than when running with the screen on! I think previously on Manjaro (after getting it to work) it would go to the "red" LED when in suspend, and would require the power key to "wake up" but the consumption (during suspend) was "good" (it could "sleep" for a day without going "flat").
But with Armbian all LED go out, it does disconnect wifi (so isn't just "screen off") but will wake when hitting a key. Letting it sit overnight will likely fully drain the battery.
Is there a way to change the suspend / sleep behavior via armbian config or some other config file?
Sleep is delegated to systemd. See /etc/systemd/sleep.conf
If you find a better configuration please share.

At the time of implementation hardware sleep of any kind was unreliable so this mode we're using is just kernel-based sleep.
