I was being conveniently vague.... I would expect for battery reporting, probably not. Simple, single value being updated every minute or so I also don't expect to have a significant drain on performance, but keep an eye on it.
If you are wanting to keep a closer check on things, have you looked at things like the Hub Information Driver and some of the options for capturing some of the data over time, like in an InfluxDB / Grafana setup, or using WebCore charts?
