Noticed this yesterday when I checked my battery usage for the day. Had an app showing 50% of my usage in the past 24 hours, despite only 1 minute of screen time and no drain on the graph. In contrast, other apps with 20+ minutes were showing no battery usage, just the horizontal line when there isn't enough usage yet to calculate. Has anyone else had this issue? It just seems to be missing for certain hours, yet the bars are present on the graph, and the screen time and usage time is as well.
