2 years ago I would agree I can put that on the 'engineering' screen, and make it clearer. I also suspect the sample time is too short at the moment, it probably only wants to measure the time once a minute or so.
Add an 'engineering' mode which displays voltages, otherwise, just display the battery percentage. Add monitor mode where we attempt to estimate the battery life and generate a graph of the charge history over the last 5 minutes. I've also modified the progress bar to add a border so progress is clearer.
