Battery Life Effects

I've been using BTT for a few days now and have found it pretty useful. However, I don't want it to be at the expense of decent battery life.

With conservative BTT usage (for touch bar), with GoldenChaos serving as the standardized setup (in terms of scripting), how big of an impact does it have on your battery life? Let me know. Battery life wasn't horrible for me; going to try without BTT a few days to see if there's a noticeable difference myself.
